The Interactions of Relationships, Interest, and Self-Efficacy in Undergraduate Physics

NASA Astrophysics Data System (ADS)

Dou, Remy

This collected papers dissertation explores students' academic interactions in an active learning, introductory physics settings as they relate to the development of physics self-efficacy and interest. The motivation for this work extends from the national call to increase participation of students in the pursuit of science, technology, engineering, and mathematics (STEM) careers. Self-efficacy and interest are factors that play prominent roles in popular, evidence-based, career theories, including the Social cognitive career theory (SCCT) and the identity framework. Understanding how these constructs develop in light of the most pervasive characteristic of the active learning introductory physics classroom (i.e., peer-to-peer interactions) has implications on how students learn in a variety of introductory STEM classrooms and settings structured after constructivist and sociocultural learning theories. I collected data related to students' in-class interactions using the tools of social network analysis (SNA). Social network analysis has recently been shown to be an effective and useful way to examine the structure of student relationships that develop in and out of STEM classrooms. This set of studies furthers the implementation of SNA as a tool to examine self-efficacy and interest formation in the active learning physics classroom. Here I represent a variety of statistical applications of SNA, including bootstrapped linear regression (Chapter 2), structural equation modeling (Chapter 3), and hierarchical linear modeling for longitudinal analyses (Chapter 4). Self-efficacy data were collected using the Sources of Self-Efficacy for Science Courses - Physics survey (SOSESC-P), and interest data were collected using the physics identity survey. Data for these studies came from the Modeling Instruction sections of Introductory Physics with Calculus offered at Florida International University in the fall of 2014 and 2015. Analyses support the idea that students' perceptions of one another impact the development of their social network centrality, which in turn affects their self-efficacy building experiences and their overall self-efficacy. It was shown that unlike career theories that emphasize causal relationships between the development of self-efficacy and the subsequent growth of student interest, in this context student interest takes precedence before the development of student self-efficacy. This outcome also has various implications for career theories.

Effects of interactive technology, teacher scaffolding and feedback on university students' conceptual development in motion and force concepts

Stecklein, Jason Jeffrey

The utilization of interactive technologies will affect learning in science classrooms of the future. And although these technologies have improved in form and function, their effective employment in university science classrooms has lagged behind the rapid development of new constructivist pedagogies and means of instruction. This dissertation examines the enlistment of instructional technologies, in particular tablet PCs and DyKnow Interactive Software, in a technologically enhanced, university-level, introductory physics course. Results of this qualitative case study of three university students indicate that (1) the use of interactive technology positively affects both student learning within force and motion and self-reported beliefs about physics, (2) ad hoc use of instructional technologies may not sufficient for effective learning in introductory physics, (3) student learners dictate the leveraging of technology in any classroom, and (4) that purposeful teacher structuring of classroom activities with technologies are essential for student construction of knowledge. This includes designing activities to elicit attention and make knowledge visible for low-level content, while augmenting student interactions and modelling procedural steps for higher-level content.

Discovery of planets outside our solar system, known as extra-solar planets or exoplanets for short, has been at the forefront of astronomical research for over 25 years. Reports of new discoveries have almost become routine; however, the excitement surrounding them has not. Amazingly, as groundbreaking as exoplanet science is, the basic physics is quite accessible to first-year physics students, as discussed in previous TPT articles. To further illustrate this point, we developed an iOS application that generates synthetic exoplanet data to provide students and teachers with interactive learning activities. Using introductory physics concepts, we demonstrate how to estimate exoplanet mass, radius, and density from the app output. These calculations form the basis for a diverse range of classroom activities. We conclude with a summary of exoplanet science resources for teachers.

Reasoning, Attitudes, and Learning: What matters in Introductory Physics?

Bateman, Melissa; Pyper, Brian

2009-05-01

Recent research has been revealing a connection between epistemological beliefs, reasoning ability and conceptual understanding. Our project has been taking data collected from the Fall `08 and Winter `09 semesters to supplement existing data in strengthening the statistical value of our sample size. We administered four tests to selected introductory physics courses: the Epistemological Beliefs Assessment for Physical Science, the Lawson Classroom Test of Scientific Reasoning, The Force Concept Inventory, and the Conceptual Survey in Electricity and Magnetism. With these data we have been comparing test results to demographics to answer questions such as: Does gender affect how we learn physics? Does past physics experience affect how we learn physics? Does past math experience affect how we learn physics? And how do math background successes compare to physics background successes? As we answer these questions, we will be better prepared in the Physics classroom and better identify the struggles of our students and solutions to help them better succeed.

Physics instructors are not blank slates either: An exploratory study of introductory physics instruction

NASA Astrophysics Data System (ADS)

Mitchell, Willyetta Adele

2009-11-01

The purpose of the study was to investigate the views of the nature of science and the classroom practices of instructors who teach introductory physics at a research intensive university. A study of this nature is necessary because calls to change how science is taught have been made since the 1800's, yet the methods of instruction have remained virtually unchanged. The conflict between how science is taught and how students learn science can be remedied by effective professional development at the university. However, training on the change process is virtually nonexistent in teacher education programs and in teacher professional development workshops at all levels. The Views About Science Survey (VASS) was first administered to a sample of twenty-nine physics instructors and graduate assistants who have taught introductory physics courses within the last five years. To assess instructional practices in introductory physics at a research extensive university, a purposeful, stratified sample of 56 classes was observed. The interactions between the students and teachers were analyzed using the Flanders Interaction Analysis. The findings suggest that the physics instructors hold a mixed view of the nature of science. The instructors' views do not necessarily indicate how they teach physics. The results also showed that the professors reported that they use elements of effective teaching practices throughout their instruction. The results of the classroom observations revealed that non interactive lecture is the dominate instructional method used. The Flander's confirms that the majority of the class time is spent with the teacher talking and the student passively listening.

Mylott, Elliot; Kutschera, Ellynne; Dunlap, Justin C.; Christensen, Warren; Widenhorn, Ralf

2016-04-01

We will describe a one-quarter pilot algebra-based introductory physics course for pre-health and life science majors. The course features videos with biomedical experts and cogent biomedically inspired physics content. The materials were used in a flipped classroom as well as an all-online environment where students interacted with multimedia materials online and prior to engaging in classroom activities. Pre-lecture questions on both the medical content covered in the video media and the physics concepts in the written material were designed to engage students and probe their understanding of physics. The course featured group discussion and peer-lead instruction. Following in-class instruction, students engaged with homework assignments which explore the connections of physics and the medical field in a quantitative manner. Course surveys showed a positive response by the vast majority of students. Students largely indicated that the course helped them to make a connection between physics and the biomedical field. The biomedical focus and different course format were seen as an improvement to previous traditional physics instruction.

A Paperless Lab Manual - Lessons Learned

NASA Astrophysics Data System (ADS)

Hatten, Daniel L.; Hatten, Maggie W.

1999-10-01

Every freshman entering Rose-Hulman Institute of Technology is equipped with a laptop computer and a software package that allow classroom and laboratory instructors the freedom to make computer-based assignments, publish course materials in electronic form, etc. All introductory physics laboratories and many of our classrooms are networked, and students routinely take their laptop computers to class/lab. The introductory physics laboratory manual was converted to HTML in the summer of 1997 and was made available to students over the Internet vice printing a paper manual during the 1998-99 school year. The aim was to reduce paper costs and allow timely updates of the laboratory experiments. A poll conducted at the end of the school year showed a generally positive student response to the online laboratory manual, with some reservations.

Preliminary investigation of instructor effects on gender gap in introductory physics

NASA Astrophysics Data System (ADS)

Kreutzer, Kimberley; Boudreaux, Andrew

2012-06-01

Gender differences in student learning in the introductory, calculus-based electricity and magnetism course were assessed by administering the Conceptual Survey of Electricity and Magnetism pre- and postcourse. As expected, male students outgained females in traditionally taught sections as well as sections that incorporated interactive engagement (IE) techniques. In two of the IE course sections, however, the gains of female students were comparable to those of male students. Classroom observations of the course sections involved were made over an extended period. In this paper, we characterize the observed instructor-student interactions using a framework from educational psychology referred to as wise schooling. Results suggest that instructor practices affect differential learning, and that wise schooling techniques may constitute an effective strategy for promoting gender equity in the physics classroom.

Taghizadeh, Sanaz; Lincoln, James

2018-04-01

The introductory physics classroom has long educated students about the properties of the atom and the nucleus. But absent from these lessons has been an informed discussion of magnetic resonance imaging (MRI) and its parent science nuclear magnetic resonance (NMR). Physics teachers should not miss the opportunity to instruct upon this highly relevant application of modern physics, especially with so many of our students planning to pursue a career in medicine. This article provides an overview of the physics of MRI and gives advice on how physics teachers can introduce this topic. Also included are some demonstration activities and a discussion of a desktop MRI apparatus that may be used by students in the lab or as a demo.

The Pythagorean Roots of Introductory Physics

NASA Astrophysics Data System (ADS)

Clarage, James B.

2013-03-01

Much of the mathematical reasoning employed in the typical introductory physics course can be traced to Pythagorean roots planted over two thousand years ago. Besides obvious examples involving the Pythagorean theorem, I draw attention to standard physics problems and derivations which often unknowingly rely upon the Pythagoreans' work on proportion, music, geometry, harmony, the golden ratio, and cosmology. Examples are drawn from mechanics, electricity, sound, optics, energy conservation and relativity. An awareness of the primary sources of the mathematical techniques employed in the physics classroom could especially benefit students and educators at schools which encourage integration of their various courses in history, science, philosophy, and the arts.

Lock, R. M.; Hazari, Z.; Sadler, P. M.; Sonnert, G.

2012-03-01

Compared to the undergraduate population, the number of students obtaining physics degrees has been declining since the 1960s. This trend continues despite the increasing number of students taking introductory physics courses in high school and college. Our work uses an ex-post facto design to study the factors that influence students' decision to pursue a career in physics at the beginning of college. These factors include high school physics classroom experiences, other science-related experiences, and students' career motivations. The data used in this study is drawn from the Persistence Research in Science and Engineering (PRiSE) Project, a large-scale study that surveyed a nationally representative sample of college/university students enrolled in introductory English courses about their interests and prior experiences in science.

Positive Impacts of Modeling Instruction on Self-Efficacy

NASA Astrophysics Data System (ADS)

Sawtelle, Vashti; Brewe, Eric; Kramer, Laird H.

2010-10-01

Analysis of the impact of Modeling Instruction (MI) on the sources of self-efficacy for students in Introductory Physics 1 will be presented. We measured self-efficacy through a quantitative diagnostic (SOSESC) developed by Fencl and Scheel [1] to investigate the impact of instruction on the sources of self-efficacy in all introductory physics classes. We collected both pre- semester data and post-semester data, and evaluated the effect of the classroom by analyzing the shift (Post-Pre). At Florida International University, a Hispanic-serving institution, we find that traditional lecture classrooms negatively impact the self-efficacy of all students, while the MI courses had no impact for all students. Further, when disaggregating the data by gender and sources of self-efficacy, we find that Modeling Instruction positively impacted the Verbal Persuasion source of self-efficacy for women. This positive impact helps to explain high rates of retention for women in the MI classes.

From Syllabus To Diagnostic Exam: Learnings from the New Faculty Workshop Applied In the Intro Physics Classroom

NASA Astrophysics Data System (ADS)

Tanoff, Michael

2009-03-01

Kalamazoo College offers a ``one-size-fits-all'' concept-based introductory physics sequence. The widely varying demographic composition of the class --- including majors in biology, chemistry, pre-med, physics, and math, along with occasional humanities majors --- adds obvious challenges to the successful learning experience. As such, educational techniques that apply across the demographic are required. Several ideas presented at the Fall 2005 New Faculty Workshop apply to the needs of this broad range of students at Kalamazoo College, including an ``organic'' course syllabus that has been allowed to grow to whatever extent necessary to address recurring student concerns and misunderstandings about course expectations, policies, and guidelines, and to provide advice on recurring themes; peer instruction for maximizing classroom value; and hiring teaching assistants with first hand experience in the course and the labs. Details on implementing these techniques, including developing a syllabus with unusual section headings such as ``Attendance and Homework Dramas'' and ``Introductory Physics Survival Requirements,'' will be presented. Success of the techniques, as evidenced by performance on diagnostic exams, class attendance, and comments from course evaluations, will be discussed.

Improving student learning and views of physics in a large enrollment introductory physics class

NASA Astrophysics Data System (ADS)

Salehzadeh Einabad, Omid

Introductory physics courses often serve as gatekeepers for many scientific and engineering programs and, increasingly, colleges are relying on large, lecture formats for these courses. Many students, however, leave having learned very little physics and with poor views of the subject. In interactive engagement (IE), classroom activities encourage students to engage with each other and with physics concepts and to be actively involved in their own learning. These methods have been shown to be effective in introductory physics classes with small group recitations. This study examined student learning and views of physics in a large enrollment course that included IE methods with no separate, small-group recitations. In this study, a large, lecture-based course included activities that had students explaining their reasoning both verbally and in writing, revise their ideas about physics concepts, and apply their reasoning to various problems. The questions addressed were: (a) What do students learn about physics concepts and how does student learning in this course compare to that reported in the literature for students in a traditional course?, (b) Do students' views of physics change and how do students' views of physics compare to that reported in the literature for students in a traditional course?, and (c) Which of the instructional strategies contribute to student learning in this course? Data included: pre-post administration of the Force Concept Inventory (FCI), classroom exams during the term, pre-post administration of the Colorado Learning Attitudes About Science Survey (CLASS), and student work, interviews, and open-ended surveys. The average normalized gain (=0.32) on the FCI falls within the medium-gain range as reported in the physics education literature, even though the average pre-test score was very low (30%) and this was the instructor's first implementation of IE methods. Students' views of physics remained relatively unchanged by instruction. Findings also indicate that the interaction of the instructional strategies together contributed to student learning. Based on these results, IE methods should be adopted in introductory physics classes, particularly in classes where students have low pre-test scores. It is also important to provide support for instructors new to IE strategies.

Does interactive instruction in introductory physics impact long-term outcomes for students?

NASA Astrophysics Data System (ADS)

Gordon, Vernita

Early college classroom experiences contribute greatly to students leaving STEM majors. Peer instruction is a research-based pedagogy in which students, in small groups in the classroom, discuss concepts and work short problems. A single study at Harvard found that taking peer-instruction introductory physics also increases persistence in science majors. To what degree, if at all, peer instruction helps retention and performance for STEM majors at large public institutions (like University of Texas, Austin) is not known. Here I describe the results of a retrospective pilot study comparing outcomes for students who took different sections of the same calculus-based introductory mechanics course in Fall 2012 and Fall 2014. Compared with traditional lecture sections, peer-instruction sections had a 50% lower drop rate, a 40% / 55% higher rate of enrollment in the 2nd/ 3rd courses in the sequence, and, for the Fall 2012 cohort, a 74% / 165% higher rate of graduating from UT Austin / the UT Austin College of Natural Sciences by Fall 2015. I will discuss weaknesses of this retrospective pilot study and present plans for an intentionally-designed study to be implemented beginning Fall 2017.

Hanging an Airplane: A Case Study in Static Equilibrium

NASA Astrophysics Data System (ADS)

Katz, Debora M.

2009-11-01

Our classrooms are filled with engineering majors who take a semester-long course in static equilibrium. Many students find this class too challenging and drop their engineering major. In our introductory physics class, we often breeze through static equilibrium; to physicists equilibrium is just a special case of Newton's second law. While it is difficult to find more time in the syllabus for any one topic, a hands-on case study may help students to develop their physical intuition about static equilibrium and may help them to succeed in their subsequent classes. This article describes a hands-on case study that you may wish to use in your classroom. (You may also wish to check a case study involving a boat published in this journal in the 1990s. ) The hands-on case study presented here can be easily modified to work at the high school or introductory college level. There are three major components: I) planning, II) doing, and III) calculating.

Identifying the elements of physics courses that impact student learning: Curriculum, instructor, peers, and assessment

NASA Astrophysics Data System (ADS)

West, Emily Lincoln Ashbaugh

Prior research across hundreds for introductory physics courses has demonstrated that traditional physics instruction does not generally lead to students learning physics concepts in a meaningful way, but that interactive-engagement physics courses do sometimes promote a great deal more student learning. In this work I analyze a reform effort in a large-enrollment, introductory, physics course. I find that evaluating a curriculum in isolation from other influences, such as the instructor implementation and the student population, is problematical. Instead, I propose a model of classroom culture identifying the curriculum, instructor, and student peer group as key components to creating a learning environment. Assessment, a key influence of classroom culture, is considered a product of the instructor/curriculum interaction. All three aspects of the classroom culture have the potential to influence student learning outcomes. I analyze the implementation of two different reformed physics series in terms of classroom culture. In a calculus-based course, I evaluate a new reform-based curriculum for the first and third quarters of instruction. In the first quarter, mechanics, I find that having an instructor teach in alignment with the philosophy of the reformed curriculum is essential, with students of only certain section instructors having improved outcomes over traditional instruction on measures of conceptual understanding. In the electromagnetism quarter of instruction, student outcomes for all reformed sections are higher than those from traditional sections in spite of variations in instructor implementation. The vast range of instructor-student interactions within such a reformed course are analyzed in an observational study, finding that some types of interactions are characteristic of particular instructors, regardless of the content studied that day. An analysis of assessment proposes an alternative grading method that is superior to the traditional grading practices, which are inadequate to consistently evaluate certain classes of test items. Those taking part in curriculum design or research in the context of physics classrooms must be aware that variations in instructor implementation, the student population, and assessment practices all have tremendous potential to influence student learning outcomes.

An evaluation of teaching methods in the introductory physics classroom

NASA Astrophysics Data System (ADS)

Savage, Lauren Michelle Williams

The introductory physics mechanics course at the University of North Carolina at Charlotte has a history of relatively high DFW rates. In 2011, the course was redesigned from the traditional lecture format to the inverted classroom format (flipped). This format inverts the classroom by introducing material in a video assigned as homework while the instructor conducts problem solving activities and guides discussions during the regular meetings. This format focuses on student-centered learning and is more interactive and engaging. To evaluate the effectiveness of the new method, final exam data over the past 10 years was mined and the pass rates examined. A normalization condition was developed to evaluate semesters equally. The two teaching methods were compared using a grade distribution across multiple semesters. Students in the inverted class outperformed those in the traditional class: "A"s increased by 22% and "B"s increased by 38%. The final exam pass rate increased by 12% under the inverted classroom approach. The same analysis was used to compare the written and online final exam formats. Surprisingly, no students scored "A"s on the online final. However, the percent of "B"s increased by 136%. Combining documented best practices from a literature review with personal observations of student performance and attitudes from first hand classroom experience as a teaching assistant in both teaching methods, reasons are given to support the continued use of the inverted classroom approach as well as the online final. Finally, specific recommendations are given to improve the course structure where weaknesses have been identified.

Explicit reflection in an introductory physics course

NASA Astrophysics Data System (ADS)

Scott, Michael Lee

This dissertation details a classroom intervention that supplements assigned in-class problems in weekly problem sets with reflective activities that are aimed to assist in knowledge integration. Using the framework of cognitive load theory, this intervention should assist in schema acquisition leading to (1) students recognizing the use and appropriately applying physical concepts across different problem contexts, and (2) enhanced physics understanding of students resulting in improved class performance. The intervention was embedded in the discussion component of an introductory, university physics course, and spanned a 14-week period. Evaluation of the intervention was based on the relative performance between a control and treatment group. Instruments used in this study to assess performance included the Force Concept Inventory (FCI), a physics problem categorization test, and four class exams. A full discussion of this implementation and the accompanying measures will be given. Possible limitations to this study and lines of future research will be proposed.

Social network analysis of a project-based introductory physics course

2016-03-01

Research suggests that students benefit from peer interaction and active engagement in the classroom. The quality, nature, effect of these interactions is currently being explored by Physics Education Researchers. Spelman College offers an introductory physics sequence that addresses content and research skills by engaging students in open-ended research projects, a form of Project-Based Learning. Students have been surveyed at regular intervals during the second semester of trigonometry-based course to determine the frequency of interactions in and out of class. These interactions can be with current or past students, tutors, and instructors. This line of inquiry focuses on metrics of Social Network analysis, such as centrality of participants as well as segmentation of groups. Further research will refine and highlight deeper questions regarding student performance in this pedagogy and course sequence.

Modeling the 2004Indian Ocean Tsunami for Introductory Physics Students

NASA Astrophysics Data System (ADS)

DiLisi, Gregory A.; Rarick, Richard A.

2006-12-01

In this paper we develop materials to address student interest in the Indian Ocean tsunami of December 2004. We discuss the physical characteristics of tsunamis and some of the specific data regarding the 2004 event. Finally, we create an easy-to-make tsunami tank to run simulations in the classroom. The simulations exhibit three dramatic signatures of tsunamis, namely, as a tsunami moves into shallow water its amplitude increases, its wavelength and speed decrease, and its leading edge becomes increasingly steep as if to "break" or "crash." Using our tsunami tank, these realistic features were easy to observe in the classroom and evoked an enthusiastic response from our students.

Wheel Diameter and Speedometer Reading

NASA Astrophysics Data System (ADS)

Murray, Clifton

2010-09-01

Most introductory physics students have seen vehicles with nonstandard wheel diameters; some may themselves drive "low-rider" cars or "big-wheel" pickup trucks. But how does changing wheel diameter affect speedometer readout for a given speed? Deriving the answer can be followed readily by students who have been introduced to rotation, and it makes a good illustration of how reasoning in physics can lead to a result that is useful outside the classroom.

Tools, Resources, and Innovations for Active Learning of Solar and Geospace Environment Content in the Undergraduate Classrooms

NASA Astrophysics Data System (ADS)

Knipp, D. J.

2013-12-01

An undergraduate course in solar and geospace (helio) physics should link fundamental principles from introductory physics and astronomy courses to concepts that appear unique, or are uniquely named in the heliophysics course. This paper discusses short topics and activities that can be addressed in an approximately 15-min class segment, that introduce students to aspects of solar, solar wind, and geospace storms that are a step beyond, or a special application of, an introductory physics concept. Some of these activities could be assigned as pre- or post- class activities as well. Many of the actives are aligned with images or diagrams in textbook, "Understanding Space Weather and the Physics Behind It," but could be easily adapted to other texts. We also address activities that link to information from space weather forecasting and/or modeling websites.

Do Active Learning Approaches in Recitation Sections Improve Student Performance? A Case Study from an Introductory Mechanics Course

NASA Astrophysics Data System (ADS)

Tobin, R. G.

2018-01-01

Abundant research leaves little question that pedagogical approaches involving active student engagement with the material, and opportunities for student-to-student discussions, lead to much better learning outcomes than traditional instructor-led, expository instructional formats, in physics and in many other fields. In introductory college physics classes, some departments have departed radically from conventional lecture-recitation-laboratory course structures, but many, including my own, retain the basic format of large-group classroom sessions (lectures) supplemented by smaller-group meetings focused on problem solving (recitations) and separate laboratory meetings. Active student engagement in the lectures is encouraged through approaches such as Peer Instruction and Interactive Lecture Demonstrations, and these approaches have been demonstrably successful.

The "Finding Physics" Project: Recognizing and Exploring Physics Outside the Classroom

NASA Astrophysics Data System (ADS)

Beck, Judith; Perkins, James

2016-11-01

Students in introductory physics classes often have difficulty recognizing the relevance of physics concepts outside the confines of the physics classroom, lab, and textbook. Even though textbooks and instructors often provide examples of physics applications from a wide array of areas, students have difficulty relating physics to their own lives. Encouraging students to apply physics to their own surroundings helps them develop the critical analysis skills of a scientifically literate and competent citizen. Fink, in his book Creating Significant Learning Experiences, emphasizes the importance of constructing opportunities to help students connect what they learn in their academic courses with past and current life experiences and link them to possible future life experiences. Several excellent papers in this journal have presented labs and activities that address this concern by encouraging teachers to bring real-world examples into the classroom or to take students into the field for data collection and observation. Alternatively, Smith suggests a writing exercise in which his students identify and explain an event in terms of their understanding of physics. In this paper we present a multiphase exercise that challenges students to find their own examples of physics from outside the classroom and analyze them using the conceptual understanding and quantitative skills which they are developing in the classroom. The ultimate goal of the "Finding Physics" project is to improve students' learning through enhancing their recognition that, to quote one participant's end-of-course survey, "Physics is everywhere!"

A Primer for Education/Outreach to the Classroom and Community

As one example of successful cooperation among major plasma/fusion research laboratories in the United States and Europe, we discuss the development of the well-known classroom teaching chart, "Fusion - Physics of a Fundamental Energy Source", and associated materials produced by the Contemporary Physics Education Project(CPEP). CPEP is a not-for-profit organization of physicists and teachers incorporated to develop teaching materials on contemporary physics topics suitable for use in the introductory (high school and college) classroom. The Fusion Chart is currently available in 7 languages: English, Flemish, French, German, Italian, Portuguese, and Spanish. The series of supporting materials include a Teacher's Guide, 7 hands-on classroom activities, and a Web supplement at http://FusEdWeb.pppl.gov/CPEP/chart.html. All materials are being used successfully in high school teacher training workshops across North America under the auspices of APS/DPP, AAPT, and PTRA (Physics Teaching Resource Agents) programs. Though the materials were developed primarily for use by classroom teachers, they are also valuable resources for individual experts who have the opportunity to make presentations to educational or civic groups. This talk will illustrate various teaching strategies which increase the effectiveness of the materials, including demonstrations of two of the classroom activities, with audience participation invited.

Information-theoretic metric as a tool to investigate nonclassical correlations

Rudolph, Alexander L.; Lamine, Brahim; Joyce, Michael; Vignolles, Hélène; Consiglio, David

2014-06-01

We report on a project to introduce interactive learning strategies (ILS) to physics classes at the Université Pierre et Marie Curie, one of the leading science universities in France. In Spring 2012, instructors in two large introductory classes, first-year, second-semester mechanics, and second-year introductory electricity and magnetism, enrolling approximately 500 and 250 students, respectively, introduced ILS into some, but not all, of the sections of each class. The specific ILS utilized were think-pair-share questions and Peer Instruction in the main lecture classrooms, and University of Washington Tutorials for Introductory Physics in recitation sections. Pre- and postinstruction assessments [Force Concept Inventory (FCI) and Conceptual Survey of Electricity and Magnetism (CSEM), respectively] were given, along with a series of demographic questions. Since not all lecture or recitation sections in these classes used ILS, we were able to compare the results of the FCI and CSEM between interactive and noninteractive classes taught simultaneously with the same curriculum. We also analyzed final exam results, as well as the results of student and instructor attitude surveys between classes. In our analysis, we argue that multiple linear regression modeling is superior to other common analysis tools, including normalized gain. Our results show that ILS are effective at improving student learning by all measures used: research-validated concept inventories and final exam scores, on both conceptual and traditional problem-solving questions. Multiple linear regression analysis reveals that interactivity in the classroom is a significant predictor of student learning, showing a similar or stronger relationship with student learning than such ascribed characteristics as parents’ education, and achieved characteristics such as grade point average and hours studied per week. Analysis of student and instructor attitudes shows that both groups believe that ILS improve student learning in the physics classroom and increase student engagement and motivation. All of the instructors who used ILS in this study plan to continue their use.

Instructional strategies for online introductory college physics based on learning styles

NASA Astrophysics Data System (ADS)

Ekwue, Eleazer U.

The practical nature of physics and its reliance on mathematical presentations and problem solving pose a challenge toward presentation of the course in an online environment for effective learning experience. Most first-time introductory college physics students fail to grasp the basic concepts of the course and the problem solving skills if the instructional strategy used to deliver the course is not compatible with the learners' preferred learning styles. This study investigates the effect of four instructional strategies based on four learning styles (listening, reading, iconic, and direct-experience) to improve learning for introductory college physics in an online environment. Learning styles of 146 participants were determined with Canfield Learning Style inventory. Of the 85 learners who completed the study, research results showed a statistically significant increase in learning performance following the online instruction in all four learning style groups. No statistically significant differences in learning were found among the four groups. However, greater significant academic improvement was found among learners with iconic and direct-experience modes of learning. Learners in all four groups expressed that the design of the unit presentation to match their individual learning styles contributed most to their learning experience. They were satisfied with learning a new physics concept online that, in their opinion, is either comparable or better than an instructor-led classroom experience. Findings from this study suggest that learners' performance and satisfaction in an online introductory physics course could be improved by using instructional designs that are tailored to learners' preferred ways of learning. It could contribute toward the challenge of providing viable online physics instruction in colleges and universities.

Some Surprising Introductory Physics Facts and Numbers

NASA Astrophysics Data System (ADS)

Mallmann, A. James

2016-04-01

In the entertainment world, people usually like, and find memorable, novels, short stories, and movies with surprise endings. This suggests that classroom teachers might want to present to their students examples of surprising facts associated with principles of physics. Possible benefits of finding surprising facts about principles of physics are opportunities to expand beyond traditional presentations—and, in some cases, to achieve a deeper and broader understanding of those principles. I believe, moreover, that some of the facts presented here may inspire physics teachers to produce some challenge problems for students.

A gender study investigating physics self-efficacy

NASA Astrophysics Data System (ADS)

Sawtelle, Vashti

The underrepresentation of women in physics has been well documented and a source of concern for both policy makers and educators. My dissertation focuses on understanding the role self-efficacy plays in retaining students, particularly women, in introductory physics. I use an explanatory mixed methods approach to first investigate quantitatively the influence of self-efficacy in predicting success and then to qualitatively explore the development of self-efficacy. In the initial quantitative studies, I explore the utility of self-efficacy in predicting the success of introductory physics students, both women and men. Results indicate that self-efficacy is a significant predictor of success for all students. I then disaggregate the data to examine how self-efficacy develops differently for women and men in the introductory physics course. Results show women rely on different sources of self-efficacy than do men, and that a particular instructional environment, Modeling Instruction, has a positive impact on these sources of self-efficacy. In the qualitative phase of the project, this dissertation focuses on the development of self-efficacy. Using the qualitative tool of microanalysis, I introduce a methodology for understanding how self-efficacy develops moment-by-moment using the lens of self-efficacy opportunities. I then use the characterizations of self-efficacy opportunities to focus on a particular course environment and to identify and describe a mechanism by which Modeling Instruction impacts student self-efficacy. Results indicate that the emphasizing the development and deployment of models affords opportunities to impact self-efficacy. The findings of this dissertation indicate that introducing key elements into the classroom, such as cooperative group work, model development and deployment, and interaction with the instructor, create a mechanism by which instructors can impact the self-efficacy of their students. Results from this study indicate that creating a model to impact the retention rates of women in physics should include attending to self-efficacy and designing activities in the classroom that create self-efficacy opportunities.

P3: a practice focused learning environment

Irving, Paul W.; Obsniuk, Michael J.; Caballero, Marcos D.

2017-09-01

There has been an increased focus on the integration of practices into physics curricula, with a particular emphasis on integrating computation into the undergraduate curriculum of scientists and engineers. In this paper, we present a university-level, introductory physics course for science and engineering majors at Michigan State University called P3 (projects and practices in physics) that is centred around providing introductory physics students with the opportunity to appropriate various science and engineering practices. The P3 design integrates computation with analytical problem solving and is built upon a curriculum foundation of problem-based learning, the principles of constructive alignment and the theoretical framework of community of practice. The design includes an innovative approach to computational physics instruction, instructional scaffolds, and a unique approach to assessment that enables instructors to guide students in the development of the practices of a physicist. We present the very positive student related outcomes of the design gathered via attitudinal and conceptual inventories and research interviews of students’ reflecting on their experiences in the P3 classroom.

Video analysis for insight and coding: Examples from tutorials in introductory physics

NASA Astrophysics Data System (ADS)

Scherr, Rachel E.

2009-12-01

The increasing ease of video recording offers new opportunities to create richly detailed records of classroom activities. These recordings, in turn, call for research methodologies that balance generalizability with interpretive validity. This paper shares methodology for two practices of video analysis: (1) gaining insight into specific brief classroom episodes and (2) developing and applying a systematic observational protocol for a relatively large corpus of video data. These two aspects of analytic practice are illustrated in the context of a particular research interest but are intended to serve as general suggestions.

The effect of the flipped model on achievement in an introductory college physics course

NASA Astrophysics Data System (ADS)

Winter, Joshua Brian

The flipped or inverted classroom model is one in which the time and place for traditional lecture and homework are reversed. Traditional lecture is replaced by online videos assigned as homework. This frees up time in class to be spent with more student centered activities such as discussion based concept questions and group problem solving. While growing in popularity, research on the effectiveness of this format is sparse. In this quasi-experimental study, two sections of an introductory algebra-based college physics course were examined over a five week period. Each section was taught with either the traditional or flipped model and physics knowledge achieved was compared using independent samples t-tests on both the instructor's unit exam and the Mechanics Baseline Test pre/posttest normalized gain. Results indicated that there was no statistically significant difference between the flipped model and the traditional lecture format. Avenues for further research are discussed.

Using a dual safeguard web-based interactive teaching approach in an introductory physics class

Li, Lie-Ming; Li, Bin; Luo, Ying

2015-06-01

We modified the Just-in-Time Teaching approach and developed a dual safeguard web-based interactive (DGWI) teaching system for an introductory physics course. The system consists of four instructional components that improve student learning by including warm-up assignments and online homework. Student and instructor activities involve activities both in the classroom and on a designated web site. An experimental study with control groups evaluated the effectiveness of the DGWI teaching method. The results indicate that the DGWI method is an effective way to improve students' understanding of physics concepts, develop students' problem-solving abilities through instructor-student interactions, and identify students' misconceptions through a safeguard framework based on questions that satisfy teaching requirements and cover all of the course material. The empirical study and a follow-up survey found that the DGWI method increased student-teacher interaction and improved student learning outcomes.

Gender Gaps in Achievement and Participation in Multiple Introductory Biology Classrooms

PubMed Central

Brownell, Sara E.; Wenderoth, Mary Pat

2014-01-01

Although gender gaps have been a major concern in male-dominated science, technology, engineering, and mathematics disciplines such as physics and engineering, the numerical dominance of female students in biology has supported the assumption that gender disparities do not exist at the undergraduate level in life sciences. Using data from 23 large introductory biology classes for majors, we examine two measures of gender disparity in biology: academic achievement and participation in whole-class discussions. We found that females consistently underperform on exams compared with males with similar overall college grade point averages. In addition, although females on average represent 60% of the students in these courses, their voices make up less than 40% of those heard responding to instructor-posed questions to the class, one of the most common ways of engaging students in large lectures. Based on these data, we propose that, despite numerical dominance of females, gender disparities remain an issue in introductory biology classrooms. For student retention and achievement in biology to be truly merit based, we need to develop strategies to equalize the opportunities for students of different genders to practice the skills they need to excel.

A GeoWall with Physics and Astronomy Applications

NASA Astrophysics Data System (ADS)

Dukes, Phillip; Bruton, Dan

2008-03-01

A GeoWall is a passive stereoscopic projection system that can be used by students, teachers, and researchers for visualization of the structure and dynamics of three-dimensional systems and data. The type of system described here adequately provides 3-D visualization in natural color for large or small groups of viewers. The name ``GeoWall'' derives from its initial development to visualize data in the geosciences.1 An early GeoWall system was developed by Paul Morin at the electronic visualization laboratory at the University of Minnesota and was applied in an introductory geology course in spring of 2001. Since that time, several stereoscopic media, which are applicable to introductory-level physics and astronomy classes, have been developed and released into the public domain. In addition to the GeoWall's application in the classroom, there is considerable value in its use as part of a general science outreach program. In this paper we briefly describe the theory of operation of stereoscopic projection and the basic necessary components of a GeoWall system. Then we briefly describe how we are using a GeoWall as an instructional tool for the classroom and informal astronomy education and in research. Finally, we list sources for several of the free software media in physics and astronomy available for use with a GeoWall system.

Teaching the history of science in physics classrooms—the story of the neutrino

NASA Astrophysics Data System (ADS)

Demirci, Neset

2016-07-01

Because there is little connection between physics concepts and real life, most students find physics very difficult. In this frontline I have provided a timely link of the historical development using the basic story of neutrino physics and integrated this into introductory modern physics courses in high schools or in higher education. In this way an instructor may be able to build on students’ curiosity in order to enhance the curriculum with some remarkable new physics. Using the history of science in the classroom shapes and improves students’ views and knowledge of the nature of science and increase students’ interest in physics.

Analysis of GPS Data Using Near Real-Time Data from the Volcano Exploration Project in the Community College Classroom (Invited)

NASA Astrophysics Data System (ADS)

House, M.; Nagy-Shadman, E.; Wilbur, B.

2010-12-01

Using real-time data or near-real-time data in the classroom is an exciting prospect in Introductory Physical Geology courses, especially since it promises to offer students a chance to experience the excitement and uncertainty associated with the study of the natural world that appeals to so many of their instructors. However, there are several obstacles to this approach in the community college. Namely, many introductory level community college earth science courses have no mathematics prerequisites; as such, a typical classroom may include a wide range of mathematical skills and many students may be unable to participate in the analysis of “real” data. Further, reliable computer access to websites offering real-time data can be spotty at some institutions and for some students on home computers. In response to this problem we have created a multipart volcano monitoring activity based on the USGS Volcano Exploration Project: Pu`u `O`o (VEPP) website. This activity is designed for freshman or sophomore level courses in Introductory Geology or Geological Hazards for non-majors. No prior math skills are assumed; the activity can be completed without prior knowledge of GPS data, volcano monitoring or Hawaiian geology. The activity consists of three parts: (1) a background lecture on basic geology of volcanoes like Kilauea and use of GPS in volcano monitoring; (2) a lab activity or a homework assignment based on near real-time data downloaded from the VEPP website; and (3) a group wrap-up that focuses on real-time data by exploring other aspects of the VEPP website. The lab activity requires examination of downloaded GPS time series data for a specified time period (this can be modified as desired by the instructor), computation of displacements, graphing of displacement vectors for identified time intervals and determination of actual motion vectors, followed by a discussion of the displacements observed. These activities are interspersed by guided questions. This activity will be tested for the first time in Introductory Physical Geology courses at Pasadena City College during Fall 2010.

Active Learning in the Physics Classroom

NASA Astrophysics Data System (ADS)

Naron, Carol

Many students enter physics classes filled with misconceptions about physics concepts. Students tend to retain these misconceptions into their adult lives, even after physics instruction. Constructivist researchers have found that students gain understanding through their experiences. Researchers have also found that active learning practices increase conceptual understanding of introductory physics students. This project study sought to examine whether incorporating active learning practices in an advanced placement physics classroom increased conceptual understanding as measured by the force concept inventory (FCI). Physics students at the study site were given the FCI as both a pre- and posttest. Test data were analyzed using two different methods---a repeated-measures t test and the Hake gain method. The results of this research project showed that test score gains were statistically significant, as measured by the t test. The Hake gain results indicated a low (22.5%) gain for the class. The resulting project was a curriculum plan for teaching the mechanics portion of Advanced Placement (AP) physics B as well as several active learning classroom practices supported by the research. This project will allow AP physics teachers an opportunity to improve their curricular practices. Locally, the results of this project study showed that research participants gained understanding of physics concepts. Social change may occur as teachers implement active learning strategies, thus creating improved student understanding of physics concepts.

2016-06-01

Problem solving is a complex process valuable in everyday life and crucial for learning in the STEM fields. To support the development of problem-solving skills it is important for researchers and curriculum developers to have practical tools that can measure the difference between novice and expert problem-solving performance in authentic classroom work. It is also useful if such tools can be employed by instructors to guide their pedagogy. We describe the design, development, and testing of a simple rubric to assess written solutions to problems given in undergraduate introductory physics courses. In particular, we present evidence for the validity, reliability, and utility of the instrument. The rubric identifies five general problem-solving processes and defines the criteria to attain a score in each: organizing problem information into a Useful Description, selecting appropriate principles (Physics Approach), applying those principles to the specific conditions in the problem (Specific Application of Physics), using Mathematical Procedures appropriately, and displaying evidence of an organized reasoning pattern (Logical Progression).

2010-10-01

In Spring 2010, the Oregon State University physics department instituted a SCALE-UP (Student-Centered Active Learning Environment for Undergraduate Programs) style studio classroom in the introductory, calculus-based physics series. In our initial implementation, comprised of two hours lecture, two hours of studio, and two hours lab work, the studio session was lead by a faculty member and either 2 GTAs or 1 GTA and 1 LA. We plan to move to a model where senior GTAs can lead studio sections after co-teaching with the faculty member. It is critical that we know how to prepare and support the instructional team in facilitating student learning in this setting. We examine GTA and LA pedagogical beliefs through reflective journaling, interviews, and personal experience of the authors. In particular, we examine how these beliefs changed over their first quarter of instruction, as well as the resources used to adapt to the new classroom environment.

We present a general physics laboratory exercise that centres around the use of the electrocardiogram sensor as an application of circuits and electronic signal filtering. Although these topics are commonly taught in the general physics classroom, many students consider topics such as alternating current as unrelated to their future professions.

Assessing gender differences in response system questions for an introductory physics course

NASA Astrophysics Data System (ADS)

Richardson, Chris T.; O'Shea, Brian W.

2013-03-01

In this work, we investigate whether gender differences are present in the iClicker student response system during introductory physics lectures in an engaged environment. We find that men and women are equally likely to respond to questions correctly and in the same amount of time. We also find that both genders make use of multiple responses in the same timescale, however, the average number of responses for a given question is significantly higher for men than women. Upon analyzing these responses, we also find men are slightly more likely than women to change their response, while the response base station is open. Both genders benefit from peer instruction by answering more quickly and correctly. The connection between previously documented timescale differences, differences in ungraded responses, and their implications for the classroom environment are discussed.

Bringing Artificial Gravity into the Classroom

NASA Astrophysics Data System (ADS)

Thompson, Grant; Aning, Isaac

2018-01-01

We recently conducted an experimental test of artificial gravity by placing various species of plants in centrifuges and analyzed the plants’ germination and growth. This research project incorporated several topics covered in undergraduate astronomy, biology, and physics courses. Given the interest of introductory astronomy students in artificial gravity and their pre-existing images of applications such as rotating spacecraft from pop culture, the results of the experiment may provide a gateway to discuss artificial gravity beyond teaching the traditional examples of Newton’s laws. We will discuss the experiment in detail and provide suggestions for how the experiment could be incorporated into your classroom.

Care and Feeding of a Paperless, Calculus-based Physics Course

Moore, Christopher; Fuller, Robert; Plano-Clark, Vicki L.; Dunbar, Steven R.

1997-04-01

Technology is playing an increasing role in our lives at home, at work, and in the classroom. We have begun a calculus-based introductory physics course to integrate mathematics and multimedia with the traditional physics content. This course relies on the use of technology to teach physics. We formulated the following rule for the conduct of the course: ''No paper is transferred between instructional staff and students that contains course information or assignments for grading.'' Implementing and maintaining this physics course within the context of the instructor goals will be discussed. Preliminary results of feedback from the students and an evaluation team will be presented.

Teaching About Racial Equity in Introductory Physics Courses

NASA Astrophysics Data System (ADS)

Daane, Abigail R.; Decker, Sierra R.; Sawtelle, Vashti

2017-09-01

Even after you have decided to tackle a problem like racial equity, it may seem daunting to broach the subject in a physics classroom. After all, the idea of a (typically White) instructor in power tackling a sensitive topic such as social justice can be scary in any (mostly White) classroom. Not only that, but physics is typically viewed as a "culture with no culture." The physicist's quest for objectivity, along with a general focus on a fixed set of laws and formulae, support the treatment of this subject as untouched by people. Sometimes it is easier to ignore the problem and just focus on the Conservation of Energy Principle. However, ignoring the striking underrepresentation of ethnic/racial minorities and women in both the physics classroom and the field at large is a great disservice to all our students. We take the position that the persistence of representation disparities in physics is evidence that culture plays a role in who and what is involved in physics. Instructors have an opportunity to explicitly address the absence of equitable circumstances in classrooms and highlight the obstacles that contribute to the disparity (e.g., varied access to learning opportunities and support structures, dominant cultural norms, stereotype threat, implicit bias, hidden curricula, etc.). We acknowledge that incorporating these discussions in a physics classroom is fraught with difficulty, but we also believe that trying to lead these discussions is better than ignoring the problem. Furthermore, a set of resources for teachers interested in leading these discussions has been developing in the physics teacher community. Rifkin offers resources for leading a two-week unit on equity designed for secondary science classrooms. Here we describe another possible pathway for integrating a shorter equity unit into the traditional content of a (predominantly White) university physics classroom, addressing racial inequity and sharing common student responses that may arise.

Patterns of Incorrect Responses on the FCI and Course Success

NASA Astrophysics Data System (ADS)

Wells, James; Mokaya, Fridah; Valente, Diego

The Force Concept Inventory (FCI) is often used to measure the effectiveness of instructional pedagogy in introductory physics courses both at the algebra- and calculus-based level. Scores on the FCI are correlated with the performance of students in a class, as measured by their final course grade. We have collected data from several semesters of first-semester introductory mechanics courses at a public 4-year university, taught in large-scale classrooms with pedagogy including elements of Just-in-Time Teaching pedagogy along with active learning course components. The data collected includes pre- and post-test FCI scores, midterm exam grades, and final course grades. We examine whether certain patterns of incorrect answers on the FCI post-test are predictive of course grades, indicating whether certain specific student preconceptions are more detrimental than others to the success of students in an introductory mechanics course.

Evolution of Student Knowledge in a Traditional Introductory Classroom

NASA Astrophysics Data System (ADS)

Sayre, Eleanor C.; Heckler, Andrew F.

2008-10-01

In the physics education research community, a common format for evaluation is pre- and post-tests. In this study, we collect student test data many times throughout a course, allowing for the measurement of the changes of student knowledge with a time resolution on the order of a few days. The data cover the first two quarters (mechanics, E&M) of a calculus-based introductory sequence populated primarily by first- and second-year engineering majors. To avoid the possibility of test-retest effects, separate and quasi-random subpopulations of students are evaluated every week of the quarter on a variety of tasks. Unsurprisingly for a traditional introductory course, there is little change on many conceptual questions. However, the data suggest that some student ideas peak and decay rapidly during a quarter, a pattern consistent with memory research yet unmeasurable by pre-/post-testing.

Role of Pre-Course Student Characteristics on Student Learning in Interactive Teaching Environments

NASA Astrophysics Data System (ADS)

Miller, Kelly Anne

The goal of this dissertation is to broaden our understanding of interactive teaching strategies, in the context of the introductory physics classroom at the undergraduate level. The dissertation is divided into four main projects, each of which investigates a specific aspect of teaching physics interactively. All four projects look towards improving the effectiveness of interactive teaching by understanding how pre-course student characteristics affect the way students learn interactively. We first discuss lecture demonstrations in the context of an interactive classroom using Peer Instruction. We study the role of predictions in conceptual learning. We examine how students' predictions affect what they report having seen during a demonstration. We also examine how student predictions affect what they recall as the outcome of the demonstration at the end of the semester. We then analyze student response patterns to conceptual questions posed during Peer Instruction. We look at the relationship between a student's tendency to switch their answer and pre-course student characteristics like science self-efficacy. Next we elucidate response timing to conceptual questions posed over the course of the semester, in two introductory physics classes taught using Peer Instruction. We look at the relationship between student response times and student characteristics like pre-course physics knowledge, science self-efficacy and gender. We study response times as a way of gaining insight into students thinking in Peer Instruction environments as well as to improve the implementation of Peer Instruction. Finally, we present work on the role of NB, an online collaborative textbook annotation tool, in a flipped, project based, physics class. We analyze the relationship between students' level of online engagement and traditional learning metrics to understand the effectiveness of NB in the context of flipped classrooms. We also report the results of experiments conducted to explore ways to steer discussion forums to produce high-quality learning interactions.

Pedagogical approaches, contextual variables, and the development of student self-efficacy in undergraduate physics courses

NASA Astrophysics Data System (ADS)

Fencl, Heidi S.; Scheel, Karen R.

2004-09-01

Self-efficacy, or a person's situation-specific belief that s/he can succeed in a given task, has been successful in a variety of educational studies for predicting behaviors such as perseverance and success (grades), and for understanding which behaviors are attempted or avoided. The focus of this study was to examine if classroom factors such as teaching strategies and classroom climate contribute to students' physics self-efficacy. 121 undergraduates in first semester, calculus-based introductory physics courses completed surveys assessing course experiences, self-efficacy and other outcome variables, and demographic information. Students in sections including a mix of teaching strategies did significantly better than students in the traditional section on outcome variables including self-efficacy. When individual strategies were examined, the strongest relationships were found between cooperative learning strategies and all sources of self-efficacy, and between climate variables and all sources of efficacy.

Using research to enhance student learning in intermediate mechanics

NASA Astrophysics Data System (ADS)

Ambrose, Bradley

2011-03-01

For many undergraduate physics majors the sophomore/junior level course in intermediate mechanics represents their first step beyond the introductory sequence. Over the past several years research has shown that intermediate mechanics students often encounter conceptual and reasoning difficulties similar to those that arise at the introductory level. Many difficulties suggest deeply-seated alternate conceptions, while others suggest loosely or spontaneously connected intuitions. Furthermore, students often do not connect the physics to the more sophisticated mathematics they are expected to use. This presentation will highlight results from research conducted at Grand Valley State University, the University of Maine (by co-PI Michael Wittmann) and pilot sites in the Intermediate Mechanics Tutorials project. These results, taken from the analysis of pretests (ungraded quizzes), written exams, and classroom observations, will illustrate specific student difficulties as well as examples of guided-inquiry teaching strategies that appear to address these difficulties.

Learning about the scale of the solar system using digital planetarium visualizations

NASA Astrophysics Data System (ADS)

Yu, Ka Chun; Sahami, Kamran; Dove, James

2017-07-01

We studied the use of a digital planetarium for teaching relative distances and sizes in introductory undergraduate astronomy classes. Inspired in part by the classic short film The Powers of Ten and large physical scale models of the Solar System that can be explored on foot, we created lectures using virtual versions of these two pedagogical approaches for classes that saw either an immersive treatment in the planetarium or a non-immersive version in the regular classroom (with N = 973 students participating in total). Students who visited the planetarium had not only the greatest learning gains, but their performance increased with time, whereas students who saw the same visuals projected onto a flat display in their classroom showed less retention over time. The gains seen in the students who visited the planetarium reveal that this medium is a powerful tool for visualizing scale over multiple orders of magnitude. However the modest gains for the students in the regular classroom also show the utility of these visualization approaches for the broader category of classroom physics simulations.

Physics of Health Sciences

NASA Astrophysics Data System (ADS)

Baublitz, Millard; Goldberg, Bennett

A one-semester algebra-based physics course is being offered to Boston University students whose major fields of study are in allied health sciences: physical therapy, athletic training, and speech, language, and hearing sciences. The classroom instruction incorporates high-engagement learning techniques including worksheets, student response devices, small group discussions, and physics demonstrations instead of traditional lectures. The use of pre-session exercises and quizzes has been implemented. The course also requires weekly laboratory experiments in mechanics or electricity. We are using standard pre- and post-course concept inventories to compare this one-semester introductory physics course to ten years of pre- and post-course data collected on students in the same majors but who completed a two-semester course.

Teaching Physics from a Reduced Gravity Environment

NASA Astrophysics Data System (ADS)

Benge, Raymond D.; Young, C.; Davis, S.; Worley, A.; Smith, L.; Gell, A.

2010-01-01

This poster reports on an educational experiment flown in January 2009 as part of NASA's Microgravity University program. The experiment flown was an investigation into the properties of harmonic oscillators in reduced gravity. Harmonic oscillators are studied in every introductory physics class. The equation for the period of a harmonic oscillator does not include the acceleration due to gravity, so the period should be independent of gravity. However, the equation for the period of a pendulum does include the acceleration due to gravity, so the period of a pendulum should appear longer under reduced gravity (such as lunar or Martian gravity) and shorter under hyper-gravity. Typical homework problems for introductory physics classes ask questions such as "What would be the period of oscillation if this experiment were performed on the Moon or Mars?” This gives students a chance to actually see the effects predicted by the equations. These environments can be simulated aboard an aircraft. Video of the experiments being performed aboard the aircraft is to be used in introductory physics classes. Students will be able to record information from watching the experiment performed aboard the aircraft in a similar manner to how they collect data in the laboratory. They can then determine if the experiment matches theory. Video and an experimental procedure are being prepared based upon this flight, and these materials will be available for download by faculty anywhere with access to the internet who wish to use the experiment in their own classrooms in both college and high school physics classes.

Examining gender differences on FCI performance in algebra and calculus based physics courses

Kreutzer, Kimberley; Boudreaux, Andrew

2009-05-01

The Force Concept Inventory (FCI) has been widely used to asses student understanding of Newtonian principles. Studies have shown a marked difference in the performance of men and women on both pre- and post-tests [1,2] and also indicate that experiential based instruction may lead to a reduction in this gender gap [1,3]. This poster presents FCI data collected at Western Washington University. Initial analysis of gender differences are consistent with those reported nationally. We also discuss factors that may contribute to the differences in performance and propose instructional strategies that are designed to address the gender gap. [4pt] [1] M.

The Impact of NSF-funded Physics Education Research at the University of Washington

NASA Astrophysics Data System (ADS)

Heron, Paula

2015-03-01

It is now well known that many students who complete introductory physics courses are unable to apply fundamental concepts in situations that involve qualitative reasoning. Systematic investigations have helped researchers understand why so many students fail to develop robust and coherent conceptual frameworks, and have led to the development of new teaching practices and materials that are far more effective than conventional ones. The Physics Education Group at the University of Washington has played a leading role in raising awareness of the need to improve instruction, and in supporting physics faculty in their efforts to do so. With support from the National Science Foundation, the group has helped build a research base that instructors can draw on, and has produced practical, flexible instructional materials that promote deeper learning in physics classrooms. Both ``Tutorials in Introductory Physics'' (Pearson, 2002) and ``Physics by Inquiry'' (Wiley, 1996) have been developed in an iterative process in which ongoing assessment of student learning plays an integral role. These materials have had a widespread and significant impact on physics teaching and on student learning from kindergarten through graduate school. In this talk I will describe the role of research in curriculum development, and speculate on the next generation of tools and resources to support physics teaching and learning.

Examining the development of knowledge for teaching a novel introductory physics curriculum

NASA Astrophysics Data System (ADS)

Seung, Eulsun

The purpose of this study was to investigate how graduate physics teaching assistants (TAs) develop professional knowledge for teaching a new undergraduate introductory physics curriculum, Matter and Interactions (M&I ). M&I has recently been adopted as a novel introductory physics course that focuses on the application of a small number of fundamental physical principles on the atomic and molecular nature of matter. In this study, I examined the process of five TAs' development of knowledge for implementing the M&I course---from the time they engaged in an M&I content and methods workshop through their first semester as TAs for the course. Through a qualitative, multiple case study research design, data was collected from multiple sources: non-participant observations, digitally recorded video, semi-structured interviews, TAs' written reflections, and field notes. The data were analyzed using the constant comparative method. The TAs' knowledge for teaching M&I was identified in three domains: pedagogical content knowledge, pedagogical knowledge, and subject matter knowledge. First, the three components of TAs' pedagogical content knowledge were identified: knowledge of the goals of M&I, knowledge of instructional strategies, and knowledge of students' learning. Second, pedagogical knowledge that the TAs demonstrated during the study fell predominantly into the category of classroom management and organization. The knowledge of classroom management and organization was categorized into two components: time management skills and group composition. Last, the TAs' subject matter knowledge that they developed through their M&I teaching experience was described in terms of the conceptual structure of the M&I curriculum, the new approach of the M&I curriculum, and specific topic knowledge. The TAs' knowledge for teaching developed from propositional knowledge to personal practical knowledge, and the process of knowledge development consisted of three phases: accepting, actualizing, and internalizing. In addition, the TAs' knowledge developed by combining various components of knowledge for teaching. Two factors that influenced the TAs' knowledge development were identified. First, the TAs' goals in the recitation class and their goals for the checkpoints in the laboratory class influenced their knowledge development. Second, various dilemmas that the TAs encountered during their teaching practice affected the TAs' knowledge development.

Without applications of physics such as counter-weighted sets and backdrops, inclined planes, stage lighting instruments, and other mechanisms for deus ex machina, dramatic productions would revert to the words only—fine for Shakespeare and Becket, but not good for audiences who are accustomed to experiencing plays with the eye as well as the ear. Pepper's Ghost is a 19th-century stage illusion, based on basic optical principles, that can find its way into your introductory classroom.

Interactive Lecture Experiments in Large Introductory Physics Classes

NASA Astrophysics Data System (ADS)

Milner-Bolotin, Marina M.; Kotlicki, A.; Rieger, G.; Bates, F.; Moll, R.; McPhee, K.; Nashon, S.

2006-12-01

We describe Interactive Lecture Experiments (ILE), which build on Interactive Lecture Demonstrations proposed by Sokoloff and Thornton (2004) and extends it by providing students with the opportunity to analyze experiments demonstrated in the lecture outside of the classroom. Real time experimental data is collected, using Logger Pro combined with the digital video technology. This data is uploaded to the Internet and made available to the students for further analysis. Student learning is assessed in the following lecture using conceptual questions (clickers). The goal of this project is to use ILE to make large lectures more interactive and promote student interest in science, critical thinking and data analysis skills. We report on the systematic study conducted using the Colorado Learning Attitudes about Science Survey, Force Concept Inventory, open-ended physics problems and focus group interviews to determine the impact of ILE on student academic achievement, motivation and attitudes towards physics. Three sections of students (750 students) experienced four ILE experiments. The surveys were administered twice and academic results for students who experienced the ILE for a particular topic were compared to the students, from a different section, who did not complete the ILE for that topic. Additional qualitative data on students’ attitudes was collected using open ended survey questions and interviews. We will present preliminary conclusions about the role of ILEs as an effective pedagogy in large introductory physics courses. Sokoloff, D.R. and R.K. Thornton (2004).

Using Research-Based Interactive Video Vignettes to Enhance Out-of-Class Learning in Introductory Physics

NASA Astrophysics Data System (ADS)

Laws, Priscilla W.; Willis, Maxine C.; Jackson, David P.; Koenig, Kathleen; Teese, Robert

2015-02-01

Ever since the first generalized computer-assisted instruction system (PLATO1) was introduced over 50 years ago, educators have been adding computer-based materials to their classes. Today many textbooks have complete online versions that include video lectures and other supplements. In the past 25 years the web has fueled an explosion of online homework and course management systems, both as blended learning and online courses. Meanwhile, introductory physics instructors have been implementing new approaches to teaching based on the outcomes of Physics Education Research (PER). A common theme of PER-based instruction has been the use of active-learning strategies designed to help students overcome alternative conceptions that they often bring to the study of physics.2 Unfortunately, while classrooms have become more active, online learning typically relies on passive lecture videos or Kahn-style3 tablet drawings. To bring active learning online, the LivePhoto Physics Group has been developing Interactive Video Vignettes (IVVs) that add interactivity and PER-based elements to short presentations. These vignettes incorporate web-based video activities that contain interactive elements and typically require students to make predictions and analyze real-world phenomena.

Active Learning in a Large General Physics Classroom.

Trousil, Rebecca

2008-04-01

In 2004, we launched a new calculus-based, introductory physics sequence at Washington University. Designed as an alternative to our traditional lecture-based sequence, the primary objectives for this new course were to actively engage students in the learning process, to significantly strengthen students' conceptual reasoning skills, to help students develop higher level quantitative problem solving skills necessary for analyzing ``real world'' problems, and to integrate modern physics into the curriculum. This talk will describe our approach, using The Six Ideas That Shaped Physics text by Thomas Moore, to creating an active learning environment in large classes as well as share our perspective on key elements for success and challenges that we face in the large class environment.

Gamification: using elements of video games to improve engagement in an undergraduate physics class

NASA Astrophysics Data System (ADS)

Rose, J. A.; O'Meara, J. M.; Gerhardt, T. C.; Williams, M.

2016-09-01

Gamification has been extensively implemented and studied in corporate settings and has proven to be more effective than traditional employee-training programs, however, few classroom studies of gamification have been reported in the literature. Our study explored the potential of gamified on-line undergraduate physics content as a mechanism to enhance student learning and motivation. Specifically, the main objective of this work was to determine whether extrinsic motivation indicators commonly used in video games could increase student engagement with course content outside of the classroom. Life Science students taking an introductory physics course were provided access to gamified multiple choice quizzes as part of their course assessment. The quizzes incorporated common gaming elements such as points, streaks, leaderboards and achievements, as well as some gamified graphical enhancements and feedback. Student attitudes and performance among those using the gamified quizzes were examined and compared to non-gamified control groups within the same course. Student engagement was quantified through examining student participation above and beyond the minimum course requirements. The results showed that gaming techniques are significantly correlated with increased engagement with course material outside of the classroom. These results may assist instructors in engaging and motivating students outside the classroom through carefully designed online and distance-delivered undergraduate physics content. Furthermore, the gaming elements incorporated in this study were not specifically tied to the physics content and can be easily translated to any educational setting.

Physics learning identity of a successful student: A plot twist

NASA Astrophysics Data System (ADS)

Li, Sissi L.; Demaree, Dedra

2013-01-01

Classroom interactions provide learning opportunities for understanding others and developing agency in a community of learners. Student learning identities were measured using a survey instrument targeting physics learning self-efficacy, expectations of classroom roles, and attitude toward social learning as components of physics learning identity. From a selection of students who scored relatively high or low on the survey sub scales, an academically successful student in an introductory physics course using an active engagement curriculum was selected to examine identity development. Findings indicate he didn't develop a sense of agency, nor did he feel a need to alter his participation, although there were ample opportunities to do so in the learning community. These results suggest that being a successful physics student in the traditional sense doesn't necessarily mean the student is successful at adopting meta-goals which are the non-content course goals of learning to think like a physicist. This student was prompted to engage meaningfully but didn't feel it was required for success which suggests that structural alignment is required to motivate students to achieve meta-goals.

Teaching assistant-student interactions in a modified SCALE-UP classroom

NASA Astrophysics Data System (ADS)

DeBeck, George; Demaree, Dedra

2012-02-01

In the spring term of 2010, Oregon State University (OSU) began using a SCALE-UP style classroom in the instruction of the introductory calculus-based physics series. Instruction in this classroom was conducted in weekly two-hour sessions facilitated by the primary professor and either two graduate teaching assistants (GTAs) or a graduate teaching assistant and an undergraduate learning assistant (LA). During the course of instruction, two of the eight tables in the room were audio and video recorded. We examine the practices of the GTAs in interacting with the students through both qualitative and quantitative analyses of these recordings. Quantitatively, significant differences are seen between the most experienced GTA and the rest. A major difference in confidence is also observed in the qualitative analysis of this GTA compared to a less experienced GTA.

Diversity of Students' background as a source for improving teaching Physics at a Liberal Arts Institution

Agrest, Mikhail

2001-11-01

Presented work is dedicated to improvement of teaching-learning process and classroom time utilization. What should students carry with them from the classroom? Enthusiasm of their teacher, understanding of the basic concepts, understanding of what they should work on at home and, of course, some notes Teaching materials, which relate concepts of Physics to each other and to a variety of concepts in other areas of knowledge and human activity were developed. This approach is based on my experience of interacting with students with diversity of backgrounds, educational goals and objectives. Those include Business and Politics, Literature and Media, everyday family and College life, etc. A supplement workbook based on teaching materials was developed to be available for students to make notes during the lectures. This method was tested in Introductory Physics classes at the College of Charleston during some past years. The teaching-learning effectiveness has been increased and positive feedback was received from students and faculty at the College and some other Universities.

PEER DEVELOPMENT OF UNDERGRADUATE ASTRONOMERS AND PHYSICISTS AT THE UNIVERSITY OF WISCONSIN - MADISON

Abler, Melissa; UW-Madison, Physics Club of

2014-01-01

The physics club at the University of Wisconsin - Madison is actively engaged in many peer-led activities that foster development of career-oriented skills. The Garage Physics program utilizes old, unwanted laboratory equipment to enable students’ in-depth exploration of classroom experiments and to investigate their own ideas. The ability to explore individual interests independently further develops research skills and assists in students’ retention of classroom knowledge. The finished products are then presented to the public at various science education and outreach events throughout the community. Sharing self-motivated projects with the public not only enhances public knowledge, understanding, and interest, but also develops valuable communication skills in the students. A self-developed introductory research guidebook helps younger club members find a mentor in the astronomy or physics departments and begin working in a research group. Senior undergraduate students also facilitate a panel each semester to discuss their experiences in acquiring and maintaining an undergraduate research position.

Development of the Modes of Collaboration framework

NASA Astrophysics Data System (ADS)

Pawlak, Alanna; Irving, Paul W.; Caballero, Marcos D.

2018-01-01

Group work is becoming increasingly common in introductory physics classrooms. Understanding how students engage in these group learning environments is important for designing and facilitating productive learning opportunities for students. We conducted a study in which we collected video of groups of students working on conceptual electricity and magnetism problems in an introductory physics course. In this setting, students needed to negotiate a common understanding and coordinate group decisions in order to complete the activity successfully. We observed students interacting in several distinct ways while solving these problems. Analysis of these observations focused on identifying the different ways students interacted and articulating what defines and distinguishes them, resulting in the development of the modes of collaboration framework. The modes of collaboration framework defines student interactions along three dimensions: social, discursive, and disciplinary content. This multidimensional approach offers a unique lens through which to consider group work and provides a flexibility that could allow the framework to be adapted for a variety of contexts. We present the framework and several examples of its application here.

Do-It-Yourself Whiteboard-Style Physics Video Lectures

NASA Astrophysics Data System (ADS)

Douglas, Scott Samuel; Aiken, John Mark; Greco, Edwin; Schatz, Michael; Lin, Shih-Yin

2017-01-01

Video lectures are increasingly being used in physics instruction. For example, video lectures can be used to "flip" the classroom, i.e., to deliver, via the Internet, content that is traditionally transmitted by in-class lectures (e.g., presenting concepts, working examples, etc.), thereby freeing up classroom time for more interactive instruction. To date, most video lectures are live lecture recordings or screencasts. The hand-animated "whiteboard" video is an alternative to these more common styles and affords unique creative opportunities such as stop-motion animation or visual "demonstrations" of phenomena that would be difficult to demo in a classroom. In the spring of 2013, a series of whiteboard-style videos were produced to provide video lecture content for Georgia Tech introductory physics instruction, including flipped courses and a MOOC. This set of videos (which also includes screencasts and live recordings) can be found on the "Your World is Your Lab" YouTube channel. In this article, we describe this method of video production, which is suitable for an instructor working solo or in collaboration with students; we explore students' engagement with these videos in a separate work. A prominent example of whiteboard animation is the "Minute Physics" video series by Henry Reich, whose considerable popularity and accessible, cartoony style were the original inspiration for our own video lectures.

Pond, Jarrad W. T.; Chini, Jacquelyn J.

2017-06-01

In this study, we explore the strategic self-regulatory and motivational characteristics of students in studio-mode physics courses at three universities with varying student populations and varying levels of success in their studio-mode courses. We survey students using questions compiled from several existing questionnaires designed to measure students' study strategies, attitudes toward and motivations for learning physics, organization of scientific knowledge, experiences outside the classroom, and demographics. Using a person-centered approach, we utilize cluster analysis methods to group students into learning profiles based on their individual responses to better understand the strategies and motives of algebra-based studio physics students. Previous studies have identified five distinct learning profiles across several student populations using similar methods. We present results from first-semester and second-semester studio-mode introductory physics courses across three universities. We identify these five distinct learning profiles found in previous studies to be present within our population of introductory physics students. In addition, we investigate interactions between these learning profiles and student demographics. We find significant interactions between a student's learning profile and their experience with high school physics, major, gender, grade expectation, and institution. Ultimately, we aim to use this method of analysis to take the characteristics of students into account in the investigation of successful strategies for using studio methods of physics instruction within and across institutions.

Although the flipped classroom model has been widely adopted in medical education, reports on its use in graduate-level public health programs are limited. This study describes the design, implementation, and evaluation of a flipped classroom redesign of an introductory epidemiology course and compares it to a traditional model. One hundred fifty Masters-level students enrolled in an introductory epidemiology course with a traditional format (in-person lecture and discussion section, at-home assignment; 2015, N = 72) and a flipped classroom format (at-home lecture, in-person discussion section and assignment; 2016, N = 78). Using mixed methods, we compared student characteristics, examination scores, and end-of-course evaluations of the 2016 flipped classroom format and the 2015 traditional format. Data on the flipped classroom format, including pre- and post-course surveys, open-ended questions, self-reports of section leader teaching practices, and classroom observations, were evaluated. There were no statistically significant differences in examination scores or students' assessment of the course between 2015 (traditional) and 2016 (flipped). In 2016, 57.1% (36) of respondents to the end-of-course evaluation found watching video lectures at home to have a positive impact on their time management. Open-ended survey responses indicated a number of strengths of the flipped classroom approach, including the freedom to watch pre-recorded lectures at any time and the ability of section leaders to clarify targeted concepts. Suggestions for improvement focused on ways to increase regular interaction with lecturers. There was no significant difference in students' performance on quantitative assessments comparing the traditional format to the flipped classroom format. The flipped format did allow for greater flexibility and applied learning opportunities at home and during discussion sections.

Graduate teaching assistants in a reformed introductory physics course: Synthesis of quantitative analyses of instructor action and qualitative analyses of instructor attitudes and perspectives

NASA Astrophysics Data System (ADS)

Calder, Austin Michael

Physics Education Research (PER) has shown us that when students have opportunities to make sense of concepts they tend to remember them better and can apply them more appropriately to new situations. PER has also revealed that an interactive, cooperative, small group environment is more conducive to achieving this than traditional lecture and recitation sections. It is useful to consider the aims of reformed instruction from the point of view of the graduate teaching assistants (GTAs) in physics, who are facilitating the instruction. The data in this dissertation comes from audio-recordings of GTAs teaching in an algebra-based introductory course; I develop a rubric for assessing the teaching practices of the GTAs which separates teaching into five categories according to the reformed practices present. The rubric and technique developed here could be used as a diagnostic for GTAs new to a reformed classroom. I also conducted surveys of the GTA participants, as well as semi-structured interviews to gain more information about the attitudes and perspectives toward reformed physics instruction. Results from this work include: (1) A diagnostic tool for teaching improvement and (2) a detailed understanding of the GTA facilitators' teaching practices in the reformed physics laboratory.

Quantitative critical thinking: Student activities using Bayesian updating

NASA Astrophysics Data System (ADS)

Warren, Aaron R.

2018-05-01

One of the central roles of physics education is the development of students' ability to evaluate proposed hypotheses and models. This ability is important not just for students' understanding of physics but also to prepare students for future learning beyond physics. In particular, it is often hoped that students will better understand the manner in which physicists leverage the availability of prior knowledge to guide and constrain the construction of new knowledge. Here, we discuss how the use of Bayes' Theorem to update the estimated likelihood of hypotheses and models can help achieve these educational goals through its integration with evaluative activities that use hypothetico-deductive reasoning. Several types of classroom and laboratory activities are presented that engage students in the practice of Bayesian likelihood updating on the basis of either consistency with experimental data or consistency with pre-established principles and models. This approach is sufficiently simple for introductory physics students while offering a robust mechanism to guide relatively sophisticated student reflection concerning models, hypotheses, and problem-solutions. A quasi-experimental study utilizing algebra-based introductory courses is presented to assess the impact of these activities on student epistemological development. The results indicate gains on the Epistemological Beliefs Assessment for Physical Science (EBAPS) at a minimal cost of class-time.

Good teaching requires thoughtful planning and creative thinking, especially when trying to engage students in material that is unfamiliar to them or encumbered by stereotypes, like aging. Classic and contemporary media can provide unique teaching opportunities in gerontology classrooms. Popular films can have a powerful influence over viewers' attitudes and perceptions, and spur in-depth discussions of aging-related topics common to introductory aging courses (e.g., ageism, abuse, inequality, caregiving, healthy aging, and intimate relationships). Additionally, films appeal to multiple learning styles, engaging a variety of learners. This article examines the value of using films in introductory aging courses, offers strategies for incorporating films in the gerontology classroom, suggests sample activities and assignments that pair popular films with aging course topics, identifies challenges of using film in various classrooms settings, and provides a detailed typology of films on each of the following aging topics: ageism and stereotypes, cognitive impairment, death and dying, diversity, family relationships, health and wellness, sexuality and intimacy, and work and retirement.

Improving Critical Skills Using Wikis and CGPS in a Physics Classroom

We report the combined use of Wikispaces (wikis) and collaborative group problem solving (CGPS) sessions conducted in introductory-level calculus-based physics classes. As a part of this new teaching tool, some essay-type problems were posted on the wiki page on a weekly basis and students were encouraged to participate in problem solving without providing numerical final answers but only the steps. Each week students were further evaluated on problem solving skills, opening up more opportunity for peer interaction through CGPS. Students developed a set of skills in decision making, problem solving, communication, negotiation, critical and independent thinking, and teamwork through the combination of wikis and CGPS.

Student anxiety in introductory biology classrooms: Perceptions about active learning and persistence in the major.

2017-01-01

Many researchers have called for implementation of active learning practices in undergraduate science classrooms as one method to increase retention and persistence in STEM, yet there has been little research on the potential increases in student anxiety that may accompany these practices. This is of concern because excessive anxiety can decrease student performance. Levels and sources of student anxiety in three introductory biology lecture classes were investigated via an online survey and student interviews. The survey (n = 327) data revealed that 16% of students had moderately high classroom anxiety, which differed among the three classes. All five active learning classroom practices that were investigated caused student anxiety, with students voluntarily answering a question or being called on to answer a question causing higher anxiety than working in groups, completing worksheets, or answering clicker questions. Interviews revealed that student anxiety seemed to align with communication apprehension, social anxiety, and test anxiety. Additionally, students with higher general anxiety were more likely to self-report lower course grade and the intention to leave the major. These data suggest that a subset of students in introductory biology experience anxiety in response to active learning, and its potential impacts should be investigated.

Learning in a Physics Classroom Community: Physics Learning Identity Construct Development, Measurement and Validation

NASA Astrophysics Data System (ADS)

Li, Sissi L.

At the university level, introductory science courses usually have high student to teacher ratios which increases the challenge to meaningfully connect with students. Various curricula have been developed in physics education to actively engage students in learning through social interactions with peers and instructors in class. This learning environment demands not only conceptual understanding but also learning to be a scientist. However, the success of student learning is typically measured in test performance and course grades while assessment of student development as science learners is largely ignored. This dissertation addresses this issue with the development of an instrument towards a measure of physics learning identity (PLI) which is used to guide and complement case studies through student interviews and in class observations. Using the conceptual framework based on Etienne Wenger's communities of practice (1998), I examine the relationship between science learning and learning identity from a situated perspective in the context of a large enrollment science class as a community of practice. This conceptual framework emphasizes the central role of identity in the practices negotiated in the classroom community and in the way students figure out their trajectory as members. Using this framework, I seek to understand how the changes in student learning identity are supported by active engagement based instruction. In turn, this understanding can better facilitate the building of a productive learning community and provide a measure for achievement of the curricular learning goals in active engagement strategies. Based on the conceptual framework, I developed and validated an instrument for measuring physics learning identity in terms of student learning preferences, self-efficacy for learning physics, and self-image as a physics learner. The instrument was pilot tested with a population of Oregon State University students taking calculus based introductory physics. The responses were analyzed using principal component exploratory factor analysis. The emergent factors were analyzed to create reliable subscales to measure PLI in terms of physics learning self-efficacy and social expectations about learning. Using these subscales, I present a case study of a student who performed well in the course but resisted the identity learning goals of the curriculum. These findings are used to support the factors that emerged from the statistical analysis and suggest a potential model of the relationships between the factors describing science learning and learning identity in large enrollment college science classes. This study offers an instrument with which to measure aspects of physics learning identity and insights on how PLI might develop in a classroom community of practice.

The effect of introducing computers into an introductory physics problem-solving laboratory

McCullough, Laura Ellen

2000-10-01

Computers are appearing in every type of classroom across the country. Yet they often appear without benefit of studying their effects. The research that is available on computer use in classrooms has found mixed results, and often ignores the theoretical and instructional contexts of the computer in the classroom. The University of Minnesota's physics department employs a cooperative-group problem solving pedagogy, based on a cognitive apprenticeship instructional model, in its calculus-based introductory physics course. This study was designed to determine possible negative effects of introducing a computerized data-acquisition and analysis tool into this pedagogy as a problem-solving tool for students to use in laboratory. To determine the effects of the computer tool, two quasi-experimental treatment groups were selected. The computer-tool group (N = 170) used a tool, designed for this study (VideoTool), to collect and analyze motion data in the laboratory. The control group (N = 170) used traditional non-computer equipment (spark tapes and Polaroid(TM) film). The curriculum was kept as similar as possible for the two groups. During the ten week academic quarter, groups were examined for effects on performance on conceptual tests and grades, attitudes towards the laboratory and the laboratory tools, and behaviors within cooperative groups. Possible interactions with gender were also examined. Few differences were found between the control and computer-tool groups. The control group received slightly higher scores on one conceptual test, but this difference was not educationally significant. The computer-tool group had slightly more positive attitudes towards using the computer tool than their counterparts had towards the traditional tools. The computer-tool group also perceived that they spoke more frequently about physics misunderstandings, while the control group felt that they discussed equipment difficulties more often. This perceptual difference interacted with gender, with the men in the control group more likely to discuss equipment difficulties than any other group. Overall, the differences between the control and quasi-experimental groups were minimal. It was concluded that carefully replacing traditional data collection and analysis tools with a computer tool had no negative effects on achievement, attitude, group behavior, and did not interact with gender.

A comparative study of traditional lecture methods and interactive lecture methods in introductory geology courses for non-science majors at the college level

NASA Astrophysics Data System (ADS)

Hundley, Stacey A.

In recent years there has been a national call for reform in undergraduate science education. The goal of this reform movement in science education is to develop ways to improve undergraduate student learning with an emphasis on developing more effective teaching practices. Introductory science courses at the college level are generally taught using a traditional lecture format. Recent studies have shown incorporating active learning strategies within the traditional lecture classroom has positive effects on student outcomes. This study focuses on incorporating interactive teaching methods into the traditional lecture classroom to enhance student learning for non-science majors enrolled in introductory geology courses at a private university. Students' experience and instructional preferences regarding introductory geology courses were identified from survey data analysis. The information gained from responses to the questionnaire was utilized to develop an interactive lecture introductory geology course for non-science majors. Student outcomes were examined in introductory geology courses based on two teaching methods: interactive lecture and traditional lecture. There were no significant statistical differences between the groups based on the student outcomes and teaching methods. Incorporating interactive lecture methods did not statistically improve student outcomes when compared to traditional lecture teaching methods. However, the responses to the survey revealed students have a preference for introductory geology courses taught with lecture and instructor-led discussions and students prefer to work independently or in small groups. The results of this study are useful to individuals who teach introductory geology courses and individuals who teach introductory science courses for non-science majors at the college level.

Investigating and accounting for physics graduate students' tutorial classroom practice

NASA Astrophysics Data System (ADS)

Goertzen, Renee Michelle

Physics Education researchers have been working to understanding how students learn physics, which has led to the creation of a body of research-based curricula. It is equally important to study novice instructors, graduate teaching assistants (TAs), who often teach these students. The study of TAs has similarities to how students have been studied: it is important to identify what preconceptions they often enter the classroom with, what resources they may have that they could apply to their physics teaching, and how both the classroom environment and past experiences affect what they are doing in the classroom. Although TAs are responsible for a significant portion of students' instruction at many universities, science TAs and their teaching have not been the focus of any significant amount of study. This dissertation begins to fill this gap by examining physics graduate students who teach discussion sections for introductory courses using tutorials, which are guided worksheets completed by groups of students. While assisting students with their conceptual understanding of physics, TAs are also expected to convey classroom norms of constructing arguments and listening and responding to the reasoning of others. Physics graduate students enter into the role of tutorial TA having relative content expertise but minimal or no pedagogical expertise. This analysis contends that considering the broader influences on TAs can account for TA behavior. Observations from two institutions (University of Colorado, Boulder and University of Maryland, College Park) show that TAs have different valuations (or buy-in) of the tutorials they teach, which have specific, identifiable consequences in the classroom. These differences can be explained by differences in the TAs' different teaching environments. Next, I examine cases of a behavior shared by three TAs, in which they focus on relatively superficial indicators of knowledge. Because the beliefs that underlie their teaching decisions vary, I argue that understanding and addressing the TAs individual beliefs will lead to more effective professional development. Lastly, this analysis advocates a new perspective on TA professional development: one in which TAs' ideas about teaching are taken to be interesting, plausible, and potentially productive.

Students' network integration as a predictor of persistence in introductory physics courses

Zwolak, Justyna P.; Dou, Remy; Williams, Eric A.; Brewe, Eric

2017-06-01

Increasing student retention (successfully finishing a particular course) and persistence (continuing through a sequence of courses or the major area of study) is currently a major challenge for universities. While students' academic and social integration into an institution seems to be vital for student retention, research into the effect of interpersonal interactions is rare. We use network analysis as an approach to investigate academic and social experiences of students in the classroom. In particular, centrality measures identify patterns of interaction that contribute to integration into the university. Using these measures, we analyze how position within a social network in a Modeling Instruction (MI) course—an introductory physics course that strongly emphasizes interactive learning—predicts their persistence in taking a subsequent physics course. Students with higher centrality at the end of the first semester of MI are more likely to enroll in a second semester of MI. Moreover, we found that chances of successfully predicting individual student's persistence based on centrality measures are fairly high—up to 75%, making the centrality a good predictor of persistence. These findings suggest that increasing student social integration may help in improving persistence in science, technology, engineering, and mathematics fields.

2017-02-01

Although the advent and popularization of the "flipped classroom" tends to center around at-home video lectures, teachers are increasingly turning to at-home labs for enhanced student engagement. This paper describes two simple at-home experiments that can be accomplished in the kitchen. The first experiment analyzes the density of four liquids using a waterproof case and a smartphone barometer in a container, sink, or tub. The second experiment determines the relationship between pressure and temperature of an ideal gas in a constant volume container placed momentarily in a refrigerator freezer. These experiences provide a ripe opportunity both for learning fundamental physics concepts as well as to investigate a variety of error analysis techniques that are frequently overlooked in introductory physics courses.

Why do they not answer and do they really learn? A case study in analysing student response flows in introductory physics using an audience response system

NASA Astrophysics Data System (ADS)

Jääskeläinen, Markku; Lagerkvist, Andreas

2017-07-01

In this paper we investigate teaching with a classroom response system in introductory physics with emphasis on two issues. First, we discuss retention between question rounds and the reasons why students avoid answering the question a second time. A question with declining response rate was followed by a question addressing the student reasons for not answering. We find that there appear to be several reasons for the observed decline, and that the students need to be reminded. We argue that small drops are unimportant as the process appears to work despite the drops. Second, we discuss the dynamics of learning in a concept-sequence in electromagnetism, where a majority of the students, despite poor statistics in a first round, manage to answer a followup question correctly. In addition, we analyse the response times for both situations to connect with research on student reasoning on situations with misconception-like answers. From the combination of the answer flows and response time behaviours we find it plausible that conceptual learning occurred during the discussion phase.

Ubiquitous Presenter (UP)* is a digital presentation system that facilitates spontaneity and interactivity in the classroom. Using the system, an instructor with a Tablet PC can spontaneously modify prepared slides. Furthermore, students with web-enabled devices can add digital 'ink' or text to the instructor's slides and submit them to the instructor during class. We have used this system to facilitate interactive engagement techniques in an introductory physics class where approximately one-third of the students had access to a Tablet PC during class. Class time was used for Interactive Lecture Demonstrations, Peer Instruction, and group problem solving. We describe the implementation of these active learning activities with UP and Tablet PCs, show examples of student contributions, and describe the impact on the classroom setting. *http://up.ucsd.edu/about/

Gender gaps in achievement and participation in multiple introductory biology classrooms.

PubMed

Eddy, Sarah L; Brownell, Sara E; Wenderoth, Mary Pat

2014-01-01

Although gender gaps have been a major concern in male-dominated science, technology, engineering, and mathematics disciplines such as physics and engineering, the numerical dominance of female students in biology has supported the assumption that gender disparities do not exist at the undergraduate level in life sciences. Using data from 23 large introductory biology classes for majors, we examine two measures of gender disparity in biology: academic achievement and participation in whole-class discussions. We found that females consistently underperform on exams compared with males with similar overall college grade point averages. In addition, although females on average represent 60% of the students in these courses, their voices make up less than 40% of those heard responding to instructor-posed questions to the class, one of the most common ways of engaging students in large lectures. Based on these data, we propose that, despite numerical dominance of females, gender disparities remain an issue in introductory biology classrooms. For student retention and achievement in biology to be truly merit based, we need to develop strategies to equalize the opportunities for students of different genders to practice the skills they need to excel. © 2014 S.

Evolving Roles For Teaching Assistants In Introductory Courses

NASA Astrophysics Data System (ADS)

Dunbar, R. W.; Egger, A. E.; Schwartz, J. K.

2008-12-01

As we bring new research-based learning approaches, curricular innovations, and student engagement practices into the introductory science classroom, expectations of teaching assistants (TAs) should have, and have, changed. Similarly, the 21st century teaching assistant has different expectations of us. Maintaining relevance in this context means bringing TAs into an integrated teaching team that supports effective learning for students and provides structured professional development opportunities for TAs. A number of support efforts on our campus, with counterparts at many other universities, seek to optimize the instructional impact of faculty and teaching assistants, thus opening the door to enhanced student engagement (e.g. the quality of effort students put forth, their persistence in science and/or engineering courses, and their perception of scientific relevance in everyday life). Among these efforts, School of Earth Sciences course development TAs work 1:1 in advance of the term with introductory course faculty to design exercises and course materials that meet clearly articulated student learning goals or pedagogical challenges. Throughout the process, TAs are mentored by the faculty as well as science pedagogy experts. Initially funded by a major teaching award, the School is now moving to institutionalize this successful program which has broadened the definition of the TA role. Another area of optimization, reflecting Shulman's concept of pedagogical content knowledge, is our campus mandate that TA development take place within a departmental, as well as general, context. Both Chemistry and Physics expect introductory course TAs to lead interactive, guided-inquiry or tutorial-style sections. Integrating these sections with lecture and positively reinforcing course goals requires TA buy-in and a set of pedagogical facilitation skills cultivated through course-specific training and active mentoring while teaching. To better support the mentoring process in these and other departments, the MinT (Mentors in Teaching) program provides resources and a learning community for advanced graduate students who mentor TAs. There is clearly more to do, but we have come a long way from sink or swim toward an enriched infrastructure of support for teaching and learning in the introductory science classroom.

Now is an exciting time for physics students, because they have access to technology and experiments all over the world that were unthinkable a generation ago. Therefore, now is also the ideal time to bring these experiments into the classroom, so students can see what cutting edge science looks like, both in terms of the underlying physics and in terms of the technology used to gather data. With the continued running of the Large Hadron Collider at CERN, and the lab's continued dedication to providing open, worldwide access to their data, there is a unique opportunity for students to use these data in a manner very similar to how it's done in the particle physics community. In this session, we will explore ways for students to analyze real data from the CMS experiment at the LHC, plot these data to discover patterns and signals, and use these plots to determine quantities such as the invariant masses of the W, Z and Higgs bosons. Furthermore, we will show how such activities already fit well into standard introductory physics classes, and can in fact enhance already-existing lessons in the topics of momentum, kinematics, energy and electromagnetism.

Can we build a more efficient airplane? Using applied questions to teach physics

NASA Astrophysics Data System (ADS)

Bhatia, Aatish

2014-03-01

For students and for the science-interested public, applied questions can serve as a hook to learn introductory physics. Can we radically improve the energy efficiency of modern day aircraft? Are solar planes like the Solar Impulse the future of travel? How do migratory birds like the alpine swift fly nonstop for nearly seven months? Using examples from aeronautical engineering and biology, I'll discuss how undergraduate physics can shed light on these questions about transport, and place fundamental constraints on the flight properties of flying machines, whether birds or planes. Education research has shown that learners are likely to forget vast content knowledge unless they get to apply this knowledge to novel and unfamiliar situations. By applying physics to real-life problems, students can learn to build and apply quantitative models, making use of skills such as order of magnitude estimates, dimensional analysis, and reasoning about uncertainty. This applied skillset allows students to transfer their knowledge outside the classroom, and helps build connections between traditionally distinct content areas. I'll also describe the results of an education experiment at Rutgers University where my colleagues and I redesigned a 100+ student introductory physics course for social science and humanities majors to address applied questions such as evaluating the energy cost of transport, and asking whether the United States could obtain all its energy from renewable sources.

How can we help students appreciate physics education?

NASA Astrophysics Data System (ADS)

Lin, Jia-Ling; Zaki, Eman; Schmidt, Jason; Woolston, Don

2004-03-01

Helping students appreciate physics education is a formidable task, considering that many students struggle to pass introductory physics courses. Numerous efforts have been made for this undertaking because it is an important step leading to successful learning. In an out-of-classroom academic program, the Supplemental Instruction (SI) Program, we have used the approach, INSPIRE (inquiry, network, skillfulness, perseverance, intuition, reasoning, and effort), to help more students value their experiences in these courses. The method basically includes key elements outlined by experts in physics education [1]. Student responses have been encouraging. Having undergraduates as facilitators in the program is advantageous in promoting principles of physics education. Their training emphasizes tenacity, resourcefulness, understanding, support, and teamwork, i.e. TRUST. We present the organization and focus of the SI Program, and discuss how these improve learning atmosphere and facilitate learning. [1] Edward F. Redish et al, Am J. Phys. 66(3), March 1998.

Teaching from a Microgravity Environment: Harmonic Oscillator and Pendulum

NASA Astrophysics Data System (ADS)

Benge, Raymond; Young, Charlotte; Davis, Shirley; Worley, Alan; Smith, Linda; Gell, Amber

2009-04-01

This presentation reports on an educational experiment flown in January 2009 as part of NASA's Microgravity University program. The experiment flown was an investigation into the properties of harmonic oscillators in reduced gravity. Harmonic oscillators are studied in every introductory physics class. The equation for the period of a harmonic oscillator does not include the acceleration due to gravity, so the period should be independent of gravity. However, the equation for the period of a pendulum does include the acceleration due to gravity, so the period of a pendulum should appear longer under reduced gravity (such as lunar or Martian gravity) and shorter under hyper-gravity. These environments can be simulated aboard an aircraft. Video of the experiments being performed aboard the aircraft is to be used in introductory physics classes. Students will be able to record information from watching the experiment performed aboard the aircraft in a similar manner to how they collect data in the laboratory. They can then determine if the experiment matches theory. Video and an experimental procedure are being prepared based upon this flight, and these materials will be available for download by faculty anywhere with access to the internet who wish to use the experiment in their own classrooms.

A tale of two slinkies: learning about scientific models in a student-driven classroom

NASA Astrophysics Data System (ADS)

Gandhi, Punit; Berggren, Calvin; Livezey, Jesse; Olf, Ryan

2014-11-01

We describe a set of conceptual activities and hands-on experiments based around understanding the dynamics of a slinky that is hung vertically and released from rest. The motion, or lack thereof, of the bottom of the slinky after the top is dropped sparks students' curiosity by challenging their expectations and provides context for learning about scientific model building. This curriculum helps students learn about the model building process by giving them an opportunity to enlist their collective intellectual and creative resources to develop and explore two different physical models of the falling slinky system. By engaging with two complementary models, students not only have the opportunity to understand an intriguing phenomenon from multiple perspectives, but also learn deeper lessons about the nature of scientific understanding, the role of physical models, and the experience of doing science. The activities we present were part of a curriculum developed for a week-long summer program for incoming freshmen as a part of the Compass Project at UC Berkeley, but could easily be implemented in a wide range of classrooms at the high school or introductory college level.

Analysis of the Impact of Introductory Physics on Engineering Students at Texas A&M University

NASA Astrophysics Data System (ADS)

Perry, Jonathan; Bassichis, William

Introductory physics forms a major part of the foundational knowledge of engineering majors, independent of discipline and institution. While the content of introductory physics courses is consistent from institution to institution, the manner in which it is taught can vary greatly due to professor, textbook, instructional method, and overall course design. This work attempts to examine variations in student success, as measured by overall academic performance in an engineering major, and matriculation rates, based on the type of introductory physics a student took while enrolled in an engineering degree at Texas A&M University. Specific options for introductory physics at Texas A&M University include two calculus based physics courses, one traditional (UP), and one more mathematically rigorous (DP), transfer credit, and high school (AP or dual) credit. In order to examine the impact of introductory physics on a student's degree progression, data mining analyses are performed on a data set of relatively comprehensive academic records for all students enrolled as an engineering major for a minimum of one academic term. Student data has been collected for years of entering freshman beginning in 1990 and ending in 2010. Correlations will be examined between freshman level courses, including introductory physics, and follow on engineering courses, matriculation rates, and time to graduation.

Comparing the influence of physical and virtual manipulatives in the context of the Physics by Inquiry curriculum: The case of undergraduate students' conceptual understanding of heat and temperature

NASA Astrophysics Data System (ADS)

Zacharia, Zacharias C.; Constantinou, Constantinos P.

2008-04-01

We compare the effect of experimenting with physical or virtual manipulatives on undergraduate students' conceptual understanding of heat and temperature. A pre-post comparison study design was used to replicate all aspects of a guided inquiry classroom except the mode in which students performed their experiments. This study is the first on physical and virtual manipulative experimentation in physics in which the curriculum, method of instruction, and resource capabilities were explicitly controlled. The participants were 68 undergraduates in an introductory course and were randomly assigned to an experimental or a control group. Conceptual tests were administered to both groups to assess students' understanding before, during, and after instruction. The result indicates that both modes of experimentation are equally effective in enhancing students' conceptual understanding. This result is discussed in the context of an ongoing debate on the relative importance of virtual and real laboratory work in physics education.

Developing and validating a conceptual survey to assess introductory physics students’ understanding of magnetism

NASA Astrophysics Data System (ADS)

Li, Jing; Singh, Chandralekha

2017-03-01

Development of validated physics surveys on various topics is important for investigating the extent to which students master those concepts after traditional instruction and for assessing innovative curricula and pedagogies that can improve student understanding significantly. Here, we discuss the development and validation of a conceptual multiple-choice survey related to magnetism suitable for introductory physics courses. The survey was developed taking into account common students’ difficulties with magnetism concepts covered in introductory physics courses found in our investigation and the incorrect choices to the multiple-choice questions were designed based upon those common student difficulties. After the development and validation of the survey, it was administered to introductory physics students in various classes in paper-pencil format before and after traditional lecture-based instruction in relevant concepts. We compared the performance of students on the survey in the algebra-based and calculus-based introductory physics courses before and after traditional lecture-based instruction in relevant magnetism concepts. We discuss the common difficulties of introductory physics students with magnetism concepts we found via the survey. We also administered the survey to upper-level undergraduates majoring in physics and PhD students to benchmark the survey and compared their performance with those of traditionally taught introductory physics students for whom the survey is intended. A comparison with the base line data on the validated magnetism survey from traditionally taught introductory physics courses and upper-level undergraduate and PhD students discussed in this paper can help instructors assess the effectiveness of curricula and pedagogies which is especially designed to help students integrate conceptual and quantitative understanding and develop a good grasp of the concepts. In particular, if introductory physics students’ average performance in a class is significantly better than those of students in traditionally taught courses described here (and particularly when it is comparable to that of physics PhD students’ average performance discussed here), the curriculum or pedagogy used in that introductory class can be deemed effective. Moreover, we discuss the use of the survey to investigate gender differences in student performance.

Exploring the Universe Together: Cooperative Quizzes With and Without a Classroom Performance System in Astronomy 101

NASA Astrophysics Data System (ADS)

Byrd, Gene G.; Coleman, Susanna; Werneth, Charles

Our University of Alabama introductory astronomy course has large enrollments, with the usual problems of low attendance and students putting off studying until just before major exams--with predictable consequences. We tried one strategy--cooperatively answering quiz questions--during our May 2002 interim term. Classes were long: three hours a day over three weeks. Before midclass break, we presented a multiple-choice open-book-and-notes quiz to be answered after the break. Quizzes could increase grades without excessively diluting the importance of closed-book major exams. The interim 2002 final exam average was 80%, much better than the 2001 class average of 57%. During a regular semester, handing out and taking up papers would take up much time during the more frequent classes. It's also more interesting if students vote for different answers together, then see the correct answer. We obtained funds for a Classroom Performance System (CPS) consisting of two computer receiver units, a hub, and 128 TV remote-style response pads. We used the CPS during interim 2003. Ease of giving quizzes and grading permitted two shorter quizzes a day. Improvement was maintained, with a slight 3% increase. In addition, students graded the "cooperative quiz" 2002 and 2003 courses higher than the 2001 course. We also used the CPS for public astronomy events and introductory physics courses.

Implementing active-learning strategies to improve physics learning in Latin America

Alarcon, Hugo; Zavala, G.; Fernandez, R.; Benegas, J.

2006-12-01

It is evident that the most effective active-learning strategies to improve physics learning at the college level have been developed in the United States. Recently, some universities in Latin America have begun adopting such methods as a part of institutional projects, or motivated by national projects led by education authorities. In this work we will present two cases, a large-scale implementation of Tutorials in Introductory Physics (1) in Mexico supported by the institution as a part of a change in its educational model, and a medium-scale implementation of this method in Chile supported by the national government. In both experiences, the professors involved in the educational experience have previously participated in a training workshop that prepared them for implementing this strategy in the classroom. The training workshop, described elsewhere (2), was designed also under active learning premises, so teachers completed the proposed activities in the same way as their students will do. We will present the first results of these two projects. References: (1) McDermott, L. C., Shaffer, P. S., & PER (1998).

SU-E-E-02: The Use of Social Media in a Medical Physics Classroom.

PubMed

Starkschall, G

2012-06-01

The purpose of this presentation is to provide an example of how Facebook has been used in a medical physics classroom. Facebook was used in an introductory course in radiation interactions taken by graduate students in a CAMPEP-accredited medical physics program. Facebook served two major functions in the class, as a means for communicating announcements to students, and as a forum for discussion of unclear points in the course. At the end of every class, students were prompted to fill out a questionnaire asking them to identify points that were not clear. After class, all questions were posted by the instructor (so students maintained anonymity and did not have to be embarrassed by lack of knowledge). Students had 24 hr to post responses to their peers' questions. Students who responded correctly to peers' questions received additional in- class credit for their response, thus encouraging them to respond. After 24 hr, the instructor or a teaching assistant posted a response to the question. 12/16 students participated in discussions. The students who did not respond were all postdoctoral fellows (3/4 foreign) auditing the course. From 3 to 9 students typically responded to questions. Students responding to questions received credit for their responses (0.4 points per response up to a maximum of 5 points added to an in-class grade that counted for 10% of their final grade). Student evaluations of the use of Facebook were generally positive. Furthermore, use of Facebook for this application extended the time students were interacting with each other in medical physics. The use of social media in a medical physics classroom appears to be an effective tool to incorporate into a teaching methodology. © 2012 American Association of Physicists in Medicine.

Surveying college introductory physics students’ attitudes and approaches to problem solving

NASA Astrophysics Data System (ADS)

Mason, Andrew J.; Singh, Chandralekha

2016-09-01

Students’ attitudes and approaches to problem solving in physics can greatly impact their actual problem solving practices and also influence their motivation to learn and ultimately the development of expertise. We developed and validated an attitudes and approaches to problem solving (AAPS) survey and administered it to students in the introductory physics courses in a typical large research university in the US. Here, we discuss the development and validation of the survey and analysis of the student responses to the survey questions in introductory physics courses. The introductory physics students’ responses to the survey questions were also compared with those of physics faculty members and physics PhD students. We find that introductory students are in general less expert-like than the physics faculty members and PhD students. Moreover, on some AAPS survey questions, the responses of students and faculty have unexpected trends. Those trends were interpreted via individual interviews, which helped clarify reasons for those survey responses.

Buxner, S.; Meinke, B. K.; Brain, D.; Schneider, N. M.; Schultz, G. R.; Smith, D. A.; Grier, J.; Shipp, S. S.

2014-12-01

The NASA Science Mission Directorate (SMD) Science Education and Public Outreach (E/PO) community and Forums work together to bring the cutting-edge discoveries of NASA Astrophysics and Planetary Science missions to the introductory astronomy college classroom. These mission- and grant-based E/PO programs are uniquely poised to foster collaboration between scientists with content expertise and educators with pedagogy expertise. We present two new opportunities for college instructors to bring the latest NASA discoveries in Space Science into their classrooms. The NASA Science Mission Directorate (SMD) Astrophysics Education and Public Outreach Forum is coordinating the development of a pilot series of slide sets to help Astronomy 101 instructors incorporate new discoveries in their classrooms. The "Astro 101 slide sets" are presentations 5-7 slides in length on a new development or discovery from a NASA Astrophysics mission relevant to topics in introductory astronomy courses. We intend for these slide sets to help Astronomy 101 instructors include new developments (discoveries not yet in their textbooks) into the broader context of the course. In a similar effort to keep the astronomy classroom apprised of the fast moving field of planetary science, the Division of Planetary Sciences (DPS) has developed the Discovery slide sets, which are 3-slide presentations that can be incorporated into college lectures. The slide sets are targeted at the Introductory Astronomy undergraduate level. Each slide set consists of three slides which cover a description of the discovery, a discussion of the underlying science, and a presentation of the big picture implications of the discovery, with a fourth slide includes links to associated press releases, images, and primary sources. Topics span all subdisciplines of planetary science, and sets are available in Farsi and Spanish. The NASA SMD Planetary Science Forum has recently partnered with the DPS to continue producing the Discovery slides and connect them to NASA mission science.

Roadrunner physics: using cartoons to challenge student preconceptions

NASA Astrophysics Data System (ADS)

Huxford, Rachael; Ridge, Mathew; Overduin, James; Selway, Jim

The cartoon universe is governed by laws that differ radically from those in the real world, but also mirror some of our preconceptions of how the world ``should'' work. We all know that Wile E. Coyote will never be able to catch the Roadrunner with a fan attached to a sailboard, or an outboard motor submerged in a pail of water--but why, exactly? Can we attach some numbers to this knowledge? We have designed some classroom demonstrations accompanied by personal-response-type questions that use classic cartoon clips to challenge student thinking in introductory courses, prompting them to rediscover the truths of physics for themselves. We extend this idea to intermediate-level modern physics, showing that some phenomena in the cartoon universe can be reconciled with standard physics if the values of fundamental constants such as c , G and h differ radically from those in the real world. Such an approach can both heighten student interest and deepen understanding in various physics topics.

Interactive, Collaborative, Electronic Learning Logs in the Physics Classroom

NASA Astrophysics Data System (ADS)

Gosling, Chris

2006-12-01

I describe my experiences using Hickman's Interactive Collaborative Electronic Learning Logs teaching HS Physics. ICE Learning Logs are written in student groups to answer questions posed by the instructor, who then in turn responds to each group’s entry before the next class. These logs were used with non-physics majors in both algebra and calculus-based introductory physics courses, and also at the high school level. I found ICE Learning Logs were found to be a clear improvement over traditional student journals. Excerpts from group entries will be presented to demonstrate the group identities that formed as well as the utility of the journals to probe for conceptual understanding. In addition, the ICE Learning Logs served as an excellent resource for students to review before exams and also to examine for critical moments to reflect on in formal essays. Hickman, P. (2000).

Contrasting grading approaches in introductory physics and quantum mechanics: The case of graduate teaching assistants

NASA Astrophysics Data System (ADS)

Marshman, Emily; Sayer, Ryan; Henderson, Charles; Singh, Chandralekha

2017-06-01

At large research universities, physics graduate teaching assistants (TAs) are often responsible for grading in courses at all levels. However, few studies have focused on TAs' grading practices in introductory and advanced physics courses. This study was designed to investigate whether physics graduate TAs grade students in introductory physics and quantum mechanics using different criteria and if so, why they may be inclined to do so. To investigate possible discrepancies in TAs' grading approaches in courses at different levels, we implemented a sequence of instructional activities in a TA professional development course that asked TAs to grade student solutions of introductory physics and upper-level quantum mechanics problems and explain why, if at all, their grading approaches were different or similar in the two contexts. We analyzed the differences in TAs' grading approaches in the two contexts and discuss the reasons they provided for the differences in their grading approaches in introductory physics and quantum mechanics in individual interviews, class discussions, and written responses. We find that a majority of the TAs graded solutions to quantum mechanics problems differently than solutions to introductory physics problems. In quantum mechanics, the TAs focused more on physics concepts and reasoning and penalized students for not showing evidence of understanding. The findings of the study have implications for TA professional development programs, e.g., the importance of helping TAs think about the difficulty of a problem from an introductory students' perspective and reflecting on the benefits of formative assessment.

A collaborative learning approach for service-oriented introductory physics

NASA Astrophysics Data System (ADS)

Smith, Michael R.

1997-03-01

I have taught algebra-based introductory physics for six years to liberal arts students. It was primarily a service course for students majoring in Athletic Training, Physical Therapy, Geology, Biology, and Pre-Med. The typical student was characterized by having a minimal math and problem-solving proficiency. There also was a pattern of students being predisposed to memorizing facts and formulas, and attempting to solve problems by finding the correct formula and "plugging in" numbers to get an answer. The students seemed to have a minimal ability in deductive reasoning and problem solving, starting from basic principles. It is no wonder that they entered the introductory physics service course with extreme trepidation, based upon a strongly perceived physics phobia. A standard lecture format was used for the class size of approximately 25-30 students; and an attempt was always made to engage the students through the Socratic approach, by asking leading questions during the course of the lecture. The students were relatively unprepared and couldn't participate in the class, and often responded antagonistically. They indicated they didn't want to be asked to think about an issue, but would rather just be told the facts so they could take specific notes for subsequent memorization. It was clear from the results of the open book exams given during the semester that the majority of students could not approach problem solving using deductive reasoning based on basic principles, but relied on attempting to force-fit the problem into a worked example in the text (often out of context, with illogical results). The absentee rate in the classroom was usually around 30-40%. The academic administration of my liberal arts university has the policy of formal course evaluations by the students at the end of each semester. The evaluation questionnaire appears to be primarily a measurement of the stress level of the student during the course, and the evaluation score I received for the service physics course was typically on the order of 3 out of a possible 5; a score considered unsatisfactory by the administration.

High-Speed Video Analysis in a Conceptual Physics Class

NASA Astrophysics Data System (ADS)

Desbien, Dwain M.

2011-09-01

The use of probe ware and computers has become quite common in introductory physics classrooms. Video analysis is also becoming more popular and is available to a wide range of students through commercially available and/or free software.2,3 Video analysis allows for the study of motions that cannot be easily measured in the traditional lab setting and also allows real-world situations to be analyzed. Many motions are too fast to easily be captured at the standard video frame rate of 30 frames per second (fps) employed by most video cameras. This paper will discuss using a consumer camera that can record high-frame-rate video in a college-level conceptual physics class. In particular this will involve the use of model rockets to determine the acceleration during the boost period right at launch and compare it to a simple model of the expected acceleration.

Just-in-Time Teaching Exercises to Engage Students in an Introductory-Level Dinosaur Course

Guertin, Laura A.; Zappe, Sarah E.; Kim, Heeyoung

2007-12-01

The Just-in-Time Teaching (JiTT) technique allows students to be engaged in course material outside of the classroom by answering web-based questions. The responses are summarized and presented to students in class with a follow-up active learning exercise. College students enrolled in an introductory-level general education geoscience course were surveyed over a two-semester period on their engagement level during lecture and perceived learning of course content. Data show that students are able to reflect on their prior knowledge and construct new knowledge with weekly graded JiTT exercises. Despite increasing and competing pressures outside of the classroom, students reported increased learning and engagement in a course with required weekly assignments.

Second teaching: An exploration of cognitive factors in small group physics learning

NASA Astrophysics Data System (ADS)

Novemsky, Lisa Forman

This inquiry was focused on an exploration of introductory physics teaching. Alan Van Heuvelen's Overview Case Study (OCS) physics was the pedagogical approach involving guided small group problem solving and stressing concepts first, before mathematics. Second teaching is a new pedagogical construct based on Vygotsky's ideas. Structured small group activity follows traditional instruction facilitating learning for non-traditional students. It is a model of structured small group activity designed to follow traditional instruction to facilitate the learning process for students who find a physics optic (way of seeing) and physics language foreign. In informal small group settins students describe, explain, elaborate, test, and defend ideas in their own familiar vernacular as they collaborate in solving problems. Collective wisdom of a collaborative group, somewhat beyond the level for each individual member, is created then recreated through self-correction. Students improved significantly in physics knowledge. In a classroom setting, small groups of non-traditional physics students engaged in second teaching were observed. Written explanations to conceptual physics questions were analyzed. Development of language usage in relationship to introductory physics concept learning was studied. Overall physics learning correlated positively with gains in language clarity thus confirming the hypothesis that language development can be linked with gains in physics knowledge. Males and females were found to be significantly different in this respect. Male gains in language clarity were closely coupled with physics learning whereas female gains in the two measures were not coupled. Physics discourse, particularly in relationship to force and motion, seems to resonate with natural developmentally acquired sex-typical male but not female discourse. Thus, for males but not for females, physics learning proceeds in a seamless fashion wherein knowledge gains are coupled with language development. Average frequency in use of the indeterminate pronoun it per person decreased. Reificiation of qualifying terms appeared in the form of a word-form problem. In the process of reifying adjectival properties students may be recapitulating the language-bound history of natural science.

Enabling Field Experiences in Introductory Geoscience Classes through the Use of Immersive Virtual Reality

NASA Astrophysics Data System (ADS)

Moysey, S. M.; Smith, E.; Sellers, V.; Wyant, P.; Boyer, D. M.; Mobley, C.; Brame, S.

2015-12-01

Although field experiences are an important aspect of geoscience education, the opportunity to provide physical world experiences to large groups of introductory students is often limited by access, logistical, and financial constraints. Our project (NSF IUSE 1504619) is investigating the use of immersive virtual reality (VR) technologies as a surrogate for real field experiences in introductory geosciences classes. We are developing a toolbox that leverages innovations in the field of VR, including the Oculus Rift and Google Cardboard, to enable every student in an introductory geology classroom the opportunity to have a first-person virtual field experience in the Grand Canyon. We have opted to structure our VR experience as an interactive game where students must explore the Canyon to accomplish a series of tasks designed to emphasize key aspects of geoscience learning. So far we have produced two demo products for the virtual field trip. The first is a standalone "Rock Box" app developed for the iPhone, which allows students to select different rock samples, examine them in 3D, and obtain basic information about the properties of each sample. The app can act as a supplement to the traditional rock box used in physical geology labs. The second product is a fully functioning VR environment for the Grand Canyon developed using satellite-based topographic and imagery data to retain real geologic features within the experience. Players can freely navigate to explore anywhere they desire within the Canyon, but are guided to points of interest where they are able to complete exercises that will be aligned with specific learning goals. To this point we have integrated elements of the "Rock Box" app within the VR environment, allowing players to examine 3D details of rock samples they encounter within the Grand Canyon. We plan to provide demos of both products and obtain user feedback during our presentation.

Variation in external representations as part of the classroom lecture:An investigation of virtual cell animations in introductory photosynthesis instruction.

Goff, Eric E; Reindl, Katie M; Johnson, Christina; McClean, Phillip; Offerdahl, Erika G; Schroeder, Noah L; White, Alan R

2017-05-01

The use of external representations (ERs) to introduce concepts in undergraduate biology has become increasingly common. Two of the most prevalent are static images and dynamic animations. While previous studies comparing static images and dynamic animations have resulted in somewhat conflicting findings in regards to learning outcomes, the benefits of each have been shown individually. Using ERs developed by the Virtual Cell Animation project, we aim to further investigate student learning using different ERs as part of an introductory biology lecture. We focus our study on the topic of photosynthesis as reports have noted that students struggle with a number of basic photosynthesis concepts. Students (n = 167) in ten sections of introductory biology laboratory were introduced to photosynthesis concepts by instructional lectures differing only in the format of the embedded ERs. Normalized gain scores were calculated, showing that students who learned with dynamic animations outperformed students who learned from static images on the posttest. The results of this study provide possible instructional guidelines for those delivering photosynthesis instruction in the introductory biology classroom. © 2016 by The International Union of Biochemistry and Molecular Biology, 45(3):226-234, 2017. © 2016 The International Union of Biochemistry and Molecular Biology.

Examining issues of underrepresented minority students in introductory physics

NASA Astrophysics Data System (ADS)

Watkins, Jessica Ellen

In this dissertation we examine several issues related to the retention of under-represented minority students in physics and science. In the first section, we show that in calculus-based introductory physics courses, the gender gap on the FCI is diminished through the use of interactive techniques, but in lower-level introductory courses, the gap persists, similar to reports published at other institutions. We find that under-represented racial minorities perform similar to their peers with comparable academic preparation on conceptual surveys, but their average exam grades and course grades are lower. We also examine student persistence in science majors; finding a significant relationship between pedagogy in an introductory physics course and persistence in science. In the second section, we look at student end-of-semester evaluations and find that female students rate interactive teaching methods a full point lower than their male peers. Looking more deeply at student interview data, we find that female students report more social issues related to the discussions in class and both male and female students cite feeling pressure to obtain the correct answer to clicker questions. Finally, we take a look an often-cited claim for gender differences in STEM participation: cognitive differences explain achievement differences in physics. We examine specifically the role of mental rotations in physics achievement and problem-solving, viewing mental rotations as a tool that students can use on physics problems. We first look at student survey results for lower-level introductory students, finding a low, but significant correlation between performance on a mental rotations test and performance in introductory physics courses. In contrast, we did not find a significant relationship for students in the upper-level introductory course. We also examine student problem-solving interviews to investigate the role of mental rotations on introductory problems.

Labatorials in introductory physics courses

NASA Astrophysics Data System (ADS)

Sobhanzadeh, Mandana; Kalman, Calvin S.; Thompson, R. I.

2017-11-01

Traditional lab sections in introductory physics courses at Mount Royal University were replaced by a new style of lab called ‘labatorials’ developed by the Physics Education Development Group at the University of Calgary. Using labatorials in introductory physics courses has lowered student anxiety and strengthened student engagement in lab sessions. Labatorials provide instant feedback to the students and instructors. Interviews with students who had completed Introductory Physics labatorials as well as the anonymous comments left by them showed that labatorials have improved student satisfaction. Students improved their understanding of concepts compared to students who had taken traditional labs in earlier years. Moreover a combination of labatorials and reflective writing can promote positive change in students’ epistemological beliefs.

Development and calibration of a concept inventory to measure introductory college astronomy and physics students' understanding of Newtonian gravity

NASA Astrophysics Data System (ADS)

Williamson, Kathryn Elizabeth

The topic of Newtonian gravity offers a unique vantage point from which to investigate and encourage conceptual change because it is something with which everyone has daily experience, and because it is taught in two courses that reach a wide variety of students - introductory-level college astronomy ("Astro 101") and physics ("Phys 101"). Informed by the constructivist theory of learning, this study characterizes and measures Astro 101 and Phys 101 students' understanding of Newtonian gravity within four conceptual domains - Directionality, Force Law, Independence of Other Forces, and Threshold. A phenomenographic analysis of Astro 101 student-supplied responses to open-ended questions about gravity results in the characterization of students' alternative mental models and misapplications of the scientific model. These student difficulties inform the development of a multiple-choice assessment instrument, the Newtonian Gravity Concept Inventory (NGCI). Classical Test Theory (CTT) statistics, student interviews, and expert review show that the NGCI is a reliable and valid tool for assessing both Astro 101 and Phys 101 students' understanding of gravity. Furthermore, the NGCI can provide extensive and robust information about differences between Astro 101 and Phys 101 students and curricula. Comparing and contrasting the Astro 101 and Phys 101 CTT values and student response patterns shows qualitative differences in each of the four conceptual domains. Additionally, performing an Item Response Theory (IRT) analysis of NGCI student response data calibrates item parameters for all Astro 101 and Phys 101 courses and provides Newtonian gravity ability estimates for each student. Physics students show significantly higher pre-instruction and post-instruction IRT abilities than astronomy students, but they show approximately equal gains. To investigate the differential effect of Astro 101 compared to Phys 101 curricula on students' overall post-instruction Newtonian gravity ability, linear regression models control for student characteristics and classroom dynamics. Results show that differences in post-instruction abilities are most influenced by students' pre-instruction abilities and the level of interactivity in the classroom, rather than the astronomy curriculum compared to the physics curriculum. These analyses show that the NGCI has broad capabilities.

Are you a ``physics person''? Understanding students' experiences, identities, and beliefs

NASA Astrophysics Data System (ADS)

Potvin, Geoff

2015-03-01

For several years, there has been much attention paid to the dearth of women in physics. Discussion has centered on various explanatory frameworks as to why women do not pursue physics in college as a career and on their persistence in such pursuits. In this talk, I will summarize efforts by our group to investigate recruitment and persistence issues for women in high school and undergraduate physics. Viewed through the lens of identity, we have repeatedly seen the importance of high school students' beliefs about the recognition they receive as a ``physics person'' to their identity development (especially so for women) and, ultimately, their physics-related career choices. Separately, we have studied the ways in which students evaluate their male and female physics teachers, which is an avenue to unravel students' beliefs and (possible) gender biases towards competency in physics. We have found statistically significant and replicable bias (in repeated independent measurements) against female physics teachers, exhibited by both male and female students. Lastly, I will report on a series of interventions that we have implemented in introductory college physics classrooms as attempts to positively affect women's attitudes towards physics, and their physics identities specifically.

Reducing the gender achievement gap in college science: a classroom study of values affirmation.

PubMed

Miyake, Akira; Kost-Smith, Lauren E; Finkelstein, Noah D; Pollock, Steven J; Cohen, Geoffrey L; Ito, Tiffany A

2010-11-26

In many science, technology, engineering, and mathematics disciplines, women are outperformed by men in test scores, jeopardizing their success in science-oriented courses and careers. The current study tested the effectiveness of a psychological intervention, called values affirmation, in reducing the gender achievement gap in a college-level introductory physics class. In this randomized double-blind study, 399 students either wrote about their most important values or not, twice at the beginning of the 15-week course. Values affirmation reduced the male-female performance and learning difference substantially and elevated women's modal grades from the C to B range. Benefits were strongest for women who tended to endorse the stereotype that men do better than women in physics. A brief psychological intervention may be a promising way to address the gender gap in science performance and learning.

Function plot response: A scalable system for teaching kinematics graphs

NASA Astrophysics Data System (ADS)

Laverty, James; Kortemeyer, Gerd

2012-08-01

Understanding and interpreting graphs are essential skills in all sciences. While students are mostly proficient in plotting given functions and reading values off graphs, they frequently lack the ability to construct and interpret graphs in a meaningful way. Students can use graphs as representations of value pairs, but often fail to interpret them as the representation of functions, and mostly fail to use them as representations of physical reality. Working with graphs in classroom settings has been shown to improve student abilities with graphs, particularly when the students can interact with them. We introduce a novel problem type in an online homework system, which requires students to construct the graphs themselves in free form, and requires no hand-grading by instructors. Initial experiences using the new problem type in an introductory physics course are reported.

Toward understanding writing to learn in physics: Investigating student writing

NASA Astrophysics Data System (ADS)

Demaree, Dedra

It is received wisdom that writing in a discipline helps students learn the discipline, and millions of dollars have been committed at many universities to supporting such writing. We show that evidence for effectiveness is anecdotal, and that little data-based material informs these prejudices. This thesis begins the process of scientific study of writing in the discipline, in specific, in physics, and creates means to judge whether such writing is effective. The studies culminating in this thesis are an aggressive start to addressing these complex questions. Writing is often promoted as an activity that, when put into classrooms in specific disciplines, not only helps students learn to write in the methods of that discipline but also helps students learn content knowledge. Students at the Ohio State University are being asked to write more in introductory courses, and the Engineering schools want their students to have more writing skills for the job market. Combined with the desire of many educators to have students be able to explain the course content knowledge clearly, it would seem that writing activities would be important and useful in physics courses. However, the question of whether writing helps learning or whether students learn writing within a non-English classroom helps learning in the discipline are open to debate, and data are needed before such claims can be made. This thesis presents several studies aimed at understanding the correlation of writing and content, and tracking and characterizing student writing behaviors to see how they are impacted by writing in physics courses. It consists of four parts: summer and autumn 2005 focus on writing in introductory physics labs with and without explicit instruction, while winter and spring 2006 focus on tracking and analyzing student writing and revising behavior in Physics by Inquiry (PbI). With these related projects, we establish three main results. First, there is a need for quantitative studies of Writing to Learn, and in specific of Writing to Learn within physics. Second, we have also made progress in characterizing student behaviors in an effort to quantify the study of writing: the link between writing and learning content is not obvious, and we have shown that students may not even be learning to write through practice in the context of physics. Third, we have developed a valuable new tool, a novel program to track and analyze student writing, that supplies quantitative information about student writing. (Abstract shortened by UMI.)

Introductory labs; what they don't, should, and can teach (and why)

NASA Astrophysics Data System (ADS)

Wieman, Carl

2016-03-01

Introductory physics labs are widely used and expensive. They have a wide variety of potential learning goals, but these are seldom specified and less often measured if they are achieved. We cover three different research projects on introductory labs: 1) We have done cognitive task analyses of both experimental research in physics and instructional labs. The striking differences explain much of the unhappiness expressed by students with labs: 2) We have measured the effectiveness of two introductory physics lab courses specifically intended to teach the physics content covered in standard introductory courses on mechanics and E & M. As measured by course exams, the benefit is 0 +/-2% for both. 3) We show how it is possible to use lab courses to teach students to correctly evaluate physical models with uncertain data. Such quantitative critical thinking is an important skill that is not learned in typical lab courses, but is well learned by our modified lab instruction.

The Role of Introductory Geosciences in Students' Quantitative Literacy

NASA Astrophysics Data System (ADS)

Wenner, J. M.; Manduca, C.; Baer, E. M.

2006-12-01

Quantitative literacy is more than mathematics; it is about reasoning with data. Colleges and universities have begun to recognize the distinction between mathematics and quantitative literacy, modifying curricula to reflect the need for numerate citizens. Although students may view geology as 'rocks for jocks', the geosciences are truthfully rife with data, making introductory geoscience topics excellent context for developing the quantitative literacy of students with diverse backgrounds. In addition, many news items that deal with quantitative skills, such as the global warming phenomenon, have their basis in the Earth sciences and can serve as timely examples of the importance of quantitative literacy for all students in introductory geology classrooms. Participants at a workshop held in 2006, 'Infusing Quantitative Literacy into Introductory Geoscience Courses,' discussed and explored the challenges and opportunities associated with the inclusion of quantitative material and brainstormed about effective practices for imparting quantitative literacy to students with diverse backgrounds. The tangible results of this workshop add to the growing collection of quantitative materials available through the DLESE- and NSF-supported Teaching Quantitative Skills in the Geosciences website, housed at SERC. There, faculty can find a collection of pages devoted to the successful incorporation of quantitative literacy in introductory geoscience. The resources on the website are designed to help faculty to increase their comfort with presenting quantitative ideas to students with diverse mathematical abilities. A methods section on "Teaching Quantitative Literacy" (http://serc.carleton.edu/quantskills/methods/quantlit/index.html) focuses on connecting quantitative concepts with geoscience context and provides tips, trouble-shooting advice and examples of quantitative activities. The goal in this section is to provide faculty with material that can be readily incorporated into existing introductory geoscience courses. In addition, participants at the workshop (http://serc.carleton.edu/quantskills/workshop06/index.html) submitted and modified more than 20 activities and model courses (with syllabi) designed to use best practices for helping introductory geoscience students to become quantitatively literate. We present insights from the workshop and other sources for a framework that can aid in increasing quantitative literacy of students from a variety of backgrounds in the introductory geoscience classroom.

Teaching Electrostatics and Entropy in Introductory Physics

NASA Astrophysics Data System (ADS)

Reeves, Mark

Entropy changes underlie the physics that dominates biological interactions. Indeed, introductory biology courses often begin with an exploration of the qualities of water that are important to living systems. However, one idea that is not explicitly addressed in most introductory physics or biology courses is important contribution of the entropy in driving fundamental biological processes towards equilibrium. I will present material developed to teach electrostatic screening in solutions and the function of nerve cells where entropic effects act to counterbalance electrostatic attraction. These ideas are taught in an introductory, calculus-based physics course to biomedical engineers using SCALEUP pedagogy. Results of student mastering of complex problems that cross disciplinary boundaries between biology and physics, as well as the challenges that they face in learning this material will be presented.

Bouncing Back From "Deflategate"

NASA Astrophysics Data System (ADS)

DiLisi, Gregory A.; Rarick, Richard A.

2015-09-01

Halfway through the 2015 AFC Championship game between the New England Patriots and Indianapolis Colts, game officials discovered that the Patriots were using underinflated footballs on their offensive snaps. A controversy ensued because the Patriots had actually supplied these balls to the game's referee just hours before kickoff. Athletes and physicists have since agreed that using underinflated footballs gives several unfair advantages to the offensive team. Media outlets have focused their attention on two possible culprits behind the deflationary debacle: either the Patriots had intentionally underinflated their supply of footballs, or the climatic conditions, coupled with the various impacts to which the balls were subjected during the course of the game, had somehow altered the internal air pressure of the balls. This controversy soon became known as "Deflategate" (the moniker makes an obvious connection to the 1970s "Watergate" scandal). The purpose of this article is to bring Deflategate into the laboratory activities of high school and undergraduate introductory physics courses. First, we provide some background information on the actual 2015 AFC Championship game and subsequent media blitz surrounding the controversy. When used in an introductory mechanics class, this information can help students contextualize Deflategate as a real-word application of the material they are learning. Next, we recast the spotlight on Deflategate from its current focus, the ideal gas law, to a new one—namely, the physics of a bouncing ball. We then use this scenario as a motivation for a fun but informative set of experiments that can be carried out using equipment already in most high school or college laboratories. The subsequent data analysis relies on three basic principles: projectile motion, conservation of energy, and linear impulse/momentum. The analysis showcases the application of introductory physics to the world of sports, brings current events into the classroom, and demonstrates how multiple problem-solving strategies can be used to examine different aspects of a single event. Finally, some experimental results are presented and discussed.

There are many difficulties in teaching science and technology in developing countries. Several different teaching strategies have to be applied in these cases. More specifically, for developing countries competencies in teaching science in the introductory classroom has attracted much attention. As a specific example we will consider the Moroccan system. In most developing countries everything is moving so slowly that the progress stays static for development. Also, any change needs time, effort and engagement. In our case we discovered that many teachers feel uncomfortable when introducing new teaching methods and evaluation in classes at introductory physics. However, the introduction of an Active Learning in our curricula showed difficulties that students have in understanding physics and especially concepts. Students were interested in having Active Learning courses much more than passive and traditional ones. Changing believes on physical phenomena and reality of the world students become more attractive and their way of thinking Science changed. The main philosophy of fostering modern hands-on learning techniques -adapted to local needs and availability of teaching resources- is elaborated. The Active Learning program provides the teachers with a conceptual evaluation instrument, drawn from relevant physics education research, giving teachers an important tool to measure student learning. We will try to describe the UNESCO Chair project in physics created in 2010 at Cadi Ayyad University since our first experience with UNESCO ALOP program. Many efforts have been done so far and the project helps now to develop more national and international collaborations between universities and Regional Academies of Education and Training. As a new result of these actions and according to our local needs, the translation of the ALOP program into Arabic is now available under the auspice of UNESCO and encouragement of international partners SPIE, ICTP, ICO and OSA.

Classroom-Based Science Research at the Introductory Level: Changes in Career Choices and Attitude

PubMed Central

Harrison, Melinda; Dunbar, David; Ratmansky, Lisa; Lopatto, David

2011-01-01

Our study, focused on classroom-based research at the introductory level and using the Phage Genomics course as the model, shows evidence that first-year students doing research learn the process of science as well as how scientists practice science. A preliminary but notable outcome of our work, which is based on a small sample, is the change in student interest in considering different career choices such as graduate education and science in general. This is particularly notable, as previous research has described research internships as clarifying or confirming rather than changing undergraduates’ decisions to pursue graduate education. We hypothesize that our results differ from previous studies of the impact of engaging in research because the students in our study are still in the early stages of their undergraduate careers. Our work builds upon the classroom-based research movement and should be viewed as encouraging to the Vision and Change in Undergraduate Biology Education movement advocated by the American Association for the Advancement of Science, the National Science Foundation, and other undergraduate education stakeholders.

The effectiveness of using multimedia computer simulations coupled with social constructivist pedagogy in a college introductory physics classroom

NASA Astrophysics Data System (ADS)

Chou, Chiu-Hsiang

Electricity and Magnetism is legendarily considered a subject incomprehensible to the students in the college introductory level. From a social constructivist perspective, learners are encouraged to assess the quantity and the quality of prior knowledge in a subject domain and to co-construct shared knowledge and understanding by implementing and building on each other's ideas. They become challenged by new data and perspectives thus stimulate a reconceptualization of knowledge and to be actively engaged in discovering new meanings based on experiences grounded in the real-world phenomena they are expected to learn. This process is categorized as a conceptual change learning environment and can facilitate learning of E & M. Computer simulations are an excellent tool to assist the teacher and leaner in achieving these goals and were used in this study. This study examined the effectiveness of computer simulations within a conceptual change learning environment and compared it to more lecture-centered, traditional ways of teaching E & M. An experimental and control group were compared and the following differences were observed. Statistic analyses were done with ANOVA (F-test). The results indicated that the treatment group significantly outperformed the control group on the achievement test, F(1,54) = 12.34, p <.05 and the treatment group had a higher rate of improvement than the control group on two subscales: Isolation of Variables and Abstract Transformation. The results from the Maryland Physics Expectations Survey (MPEX) showed that the treatment students became more field independent and were aware of more fundamental role played by physics concepts in complex problem solving. The protocol analysis of structured interviews revealed that students in the treatment group tended to visualize the problem from different aspects and articulated what they thought in a more scientific approach. Responses to the instructional evaluation questionnaire indicated overwhelming positive ratings of appropriateness and instructional effectiveness of computer simulation instruction. In conclusion, the CSI developed and evaluated in this study provided opportunities for students to refine their preconceptions and practice using new understandings. It suggests substantial promise for the computer simulation in a classroom environment.

Interpreting Assessments of Student Learning in the Introductory Physics Classroom and Laboratory

NASA Astrophysics Data System (ADS)

Dowd, Jason Edward

Assessment is the primary means of feedback between students and instructors. However, to effectively use assessment, the ability to interpret collected information is essential. We present insights into three unique, important avenues of assessment in the physics classroom and laboratory. First, we examine students' performance on conceptual surveys. The goal of this research project is to better utilize the information collected by instructors when they administer the Force Concept Inventory (FCI) to students as a pre-test and post-test of their conceptual understanding of Newtonian mechanics. We find that ambiguities in the use of the normalized gain, g, may influence comparisons among individual classes. Therefore, we propose using stratagrams, graphical summaries of the fraction of students who exhibit "Newtonian thinking," as a clearer, more informative method of both assessing a single class and comparing performance among classes. Next, we examine students' expressions of confusion when they initially encounter new material. The goal of this research project is to better understand what such confusion actually conveys to instructors about students' performance and engagement. We investigate the relationship between students' self-assessment of their confusion over material and their performance, confidence in reasoning, pre-course self-efficacy and several other measurable characteristics of engagement. We find that students' expressions of confusion are negatively related to initial performance, confidence and self-efficacy, but positively related to final performance when all factors are considered together. Finally, we examine students' exhibition of scientific reasoning abilities in the instructional laboratory. The goal of this research project is to explore two inquiry-based curricula, each of which proposes a different degree of scaffolding. Students engage in sequences of these laboratory activities during one semester of an introductory physics course. We find that students who participate in the less scaffolded activities exhibit marginally stronger scientific reasoning abilities in distinct exercises throughout the semester, but exhibit no differences in the final, common exercises. Overall, we find that, although students demonstrate some enhanced scientific reasoning skills, they fail to exhibit or retain even some of the most strongly emphasized skills.

Using multimedia learning modules in a hybrid-online course in electricity and magnetism

NASA Astrophysics Data System (ADS)

Sadaghiani, Homeyra R.

2011-06-01

We have been piloting web-based multimedia learning modules (MLMs), developed by the Physics Education Research Group at the University of Illinois at Urbana Champaign (UIUC), as a “prelecture assignment” in several introductory physics courses at California State Polytechnic University at Pomona. In this study, we report the results from a controlled study utilizing modules on electricity and magnetism as a part of a blended hybrid-online course. We asked students in the experimental section to view the MLMs prior to attending the face-to-face class, and to make sure this would not result in additional instructional time, we reduced the weekly class time by one-third. We found that despite reduced class time, student-learning outcomes were not hindered; in fact, the implementation of the UIUC MLMs resulted in a positive effect on student performance on conceptual tests and classroom discussion questions.

Transversality of Electromagnetic Waves in the Calculus--Based Introductory Physics Course

NASA Astrophysics Data System (ADS)

Burko, Lior M.

2009-05-01

Introductory calculus--based physics textbooks state that electromagnetic waves are transverse and list many of their properties, but most such textbooks do not bring forth arguments why this is so. Both physical and theoretical arguments are at a level appropriate for students of courses based on such books, and could be readily used by instructors of such courses. Here, we discuss two physical arguments (based on polarization experiments and on lack of monopole electromagnetic radiation), and the full argument for the transversality of (plane) electromagnetic waves based on the integral Maxwell equations. We also show, at a level appropriate for the introductory course, why the electric and magnetic fields in a wave are in phase and the relation of their magnitudes. We have successfully integrated this approach in the calculus--based introductory physics course at the University of Alabama in Huntsville.

The Conceptual Astronomy and Physics Education Research (CAPER) Team, based at the University of Arizona but drawing on the collective expertise of astronomy educators around the world, is conducting scholarly research and developing instructional strategies in an effort to support high-quality astronomy teaching. One avenue of research is focused on creating and validating conceptual inventories that instructors can use to measure the effectiveness of their instructional interventions. We have recently completed new inventories in the topic areas of (1) light and spectra; (2) stars and stellar formation; and (3) planetary atmospheres and the greenhouse effect. In addition, we are using results from research on students’ naive beliefs and reasoning difficulties to development instructional strategies that promote a learner centered classroom. Our research into the effectiveness of two such curriculum projects (Lecture-Tutorials for Introductory Astronomy and Ranking Tasks for Introductory Astronomy) show that these curriculum result in statistically significant gains in student understanding across a broad range of topics, much greater than lecture alone. A third avenue of research centers on improving how ASTRO 101 is taught on a national level. Informed by our continual evaluation and fine tuning of different forms of collaborative group learning and peer instruction teaching strategies, we have developed a multi-day series of workshops that are designed to help faculty better implement innovative teaching strategies that promote a learner-centered teaching environment in the ASTO 101 large lecture course. The workshops are being assessed and iteratively improved through formative evaluation approaches aimed at determining to what extent they have a positive impact on classroom practice.

We measured the personality type of the students in a large introductory physics course of mostly life science students using the True Colors instrument. We found large correlations of personality type with performance on the precourse Force Concept Inventory (FCI), both term tests, the postcourse FCI, and the final examination. We also saw correlations with the normalized gain on the FCI. The personality profile of the students in this course is very different from the profile of the physics faculty and graduate students, and also very different from the profile of students taking the introductory physics course intended for physics majors and specialists.

Fostering the Development of Quantitative Life Skills through Introductory Astronomy: Can it be Done?

NASA Astrophysics Data System (ADS)

Follette, Katherine B.; McCarthy, D. W.

2012-01-01

We present preliminary results from a student survey designed to test whether the all-important life skill of numeracy/quantitative literacy can be fostered and improved upon in college students through the vehicle of non-major introductory courses in Astronomy. Many instructors of introductory science courses for non-majors would state that a major goal of our classes is to teach our students to distinguish between science and pseudoscience, truth and fiction, in their everyday lives. It is difficult to believe that such a skill can truly be mastered without a fair amount of mathematical sophistication in the form of arithmetic, statistical and graph reading skills that many American college students unfortunately lack when they enter our classrooms. In teaching what is frequently their "terminal science course in life” can we instill in our students the numerical skills that they need to be savvy consumers, educated citizens and discerning interpreters of the ever-present polls, studies and surveys in which our society is awash? In what may well be their final opportunity to see applied mathematics in the classroom, can we impress upon them the importance of mathematical sophistication in interpreting the statistics that they are bombarded with by the media? Our study is in its second semester, and is designed to investigate to what extent it is possible to improve important quantitative skills in college students through a single semester introductory Astronomy course.

Gender differences in introductory university physics performance: The influence of high school physics preparation and affect

NASA Astrophysics Data System (ADS)

Hazari, Zahra Sana

The attrition of females studying physics after high school is a concern to the science education community. Most undergraduate science programs require introductory physics coursework. Thus, success in introductory physics is necessary for students to progress to higher levels of science study. Success also influences attitudes; if females are well-prepared, feel confident, and do well in introductory physics, they may be inclined to study physics further. This quantitative study using multilevel modeling focused on determining factors from high school physics preparation (content, pedagogy, and assessment) and the affective domain that influenced female and male performance in introductory university physics. The study controlled for some university/course level characteristics as well as student demographic and academic background characteristics. The data consisted of 1973 surveys from 54 introductory physics courses within 35 universities across the US. The results highlight high school physics and affective experiences that differentially influenced female and male performance. These experiences include: learning requirements, computer graphing/analysis, long written problems, everyday world examples, community projects, cumulative tests/quizzes, father's encouragement, family's belief that science leads to a better career, and the length of time students believed that high school physics would help in university physics. There were also experiences that had a similar influence on female and male performance. Positively related to performance were: covering fewer topics for longer periods of time, the history of physics as a recurring topic, physics-related videos, and test/quiz questions that involved calculations and/or were drawn from standardized tests. Negatively related to performance were: student-designed projects, reading/discussing labs the day before performing them, microcomputer based laboratories, discussion after demonstrations, and family's belief that science is a series of courses to pass. This study is a unique and noteworthy addition to the literature. The results paint a dynamic picture of the factors from high school physics and within the affective domain that influence students' future physics performance. The implication is that there are many aspects to the teaching of physics in high school that, although widely used and thought to be effective, need reform in their implementation in order to be beneficial to females and males in university.

Ideas for Use of an IPad in Introductory Physics Education

NASA Astrophysics Data System (ADS)

Aurora, Tarlok S.

2014-03-01

Mobile devices such as an IPad, tablet computers and smartphones offer an opportunity to collect information to facilitate physics teaching and learning. The data collected with built-in sensors, such as a video camera, may be analyzed on the mobile device itself or on a desktop computer. In this work, first, the circular motion of a steel ball rolling in a cereal bowl was analyzed to show that it consisted of two simple harmonic motions, in perpendicular directions. Secondly, motion of two balls-one dropped vertically down, and the other one launched as a projectile - was analyzed. Data was analyzed with Logger Pro software, and value of g was determined graphically. Details of the work, its limitations and additional examples will be described. The material so obtained may be used as a demonstration, in a classroom, to clarify physics concepts. In a school, where students are required to have such portable devices, one may assign such activities as homework, to enhance student engagement in learning physics. The author is thankful to USciences for the IPad; and Rich Cosgriff, Phyllis Blumberg and Elia Eschenazi for useful discussions.

Discussing underrepresentation as a means to facilitating female students' physics identity development

NASA Astrophysics Data System (ADS)

Lock, Robynne M.; Hazari, Zahra

2016-12-01

Despite the fact that approximately half of high school physics students are female, only 21% of physics bachelor's degrees are awarded to women. In a previous study, drawn from a national survey of college students in introductory English courses, five factors commonly proposed to positively impact female students' choice of a physical science career were tested using multivariate matching methods. The only factor found to have a positive effect was the explicit discussion of the underrepresentation of women in physics. In order to explore this further, a case study of the classes of one teacher reported to discuss the underrepresentation of women was conducted. Two classroom underrepresentation discussions were recorded, students and teacher were interviewed, and relevant student work was collected. Analyzing the case study data using a figured worlds framework, we found that discussing the underrepresentation of women in science explicitly creates an opportunity for students' figured worlds of professional and school science to change, and facilitates challenging their own implicit assumptions about how the world functions. Subsequently, the norms in students' figured worlds may change or become less rigid allowing for a new openness to physics identity development amongst female students.

Aesthetic Physics Education: A Symmetry Based, Physics and Fine Arts Curriculum

NASA Astrophysics Data System (ADS)

van der Veen, Jatila; Lubin, P. M.; Cook-Gumperz, J.; Raley, J. D.; Mazur, E.

2006-12-01

Physics education research in the past two decades has focused almost entirely on pedagogical methods, but the curriculum content remains unchanged. In a recent editorial in Physics Today (July, 2006, p. 10) the ability of physicists to “imagine new realities” is correlated with what are traditionally considered non-scientific skills, including imagination and creativity, qualities which are usually associated with fine arts. In view of the new developments in physics of the 21st Century, the importance of developing creativity and imagination through education is gaining recognition. We are investigating the effectiveness of teaching introductory physics from the viewpoint of symmetry, including the foundations of General Relativity and modern cosmology, without the need for the full tensor treatment. We will pilot a new course at UCSB in Winter Quarter, 2007 entitled Symmetry and Aesthetics in Introductory Physics. Our pedagogical model is based on three premises: that the introductory curriculum needs to be modernized; that mathematics should be presented as a language; and that theoretical physics has, at its core, a great deal in common with music, art, and dance. In this talk we will present the contents of our new course, and the means by which we plan to evaluate it in comparison to “regular” introductory courses. It is our hope that this modernized and integrated approach to introductory physics can also serve as a course for future teachers of primary and secondary school. This work is supported by NASA grant #20070268 and the Planck Explorer Mission.

Mediating relationship of differential products in understanding integration in introductory physics

2018-01-01

In the context of introductory physics, we study student conceptual understanding of differentials, differential products, and integrals and possible pathways to understanding these quantities. We developed a multiple choice conceptual assessment employing a variety of physical contexts probing physical understanding of these three quantities and administered the instrument to over 1000 students in first and second semester introductory physics courses. Using a regression-based mediation analysis with conceptual understanding of integration as the dependent variable, we found evidence consistent with a simple mediation model: the relationship between differentials scores and integral scores may be mediated by the understanding of differential products. The indirect effect (a quantifiable metric of mediation) was estimated as a b =0.29 , 95% CI [0.25, 0.33] for N =1102 Physics 1 students, and a b =0.27 , 95% CI [0.14, 0.48] for N =65 Physics 2 students. We also find evidence that the physical context of the questions can be an important factor. These results imply that for introductory physics courses, instructional emphasis first on differentials then on differential products in a variety of contexts may in turn promote better integral understanding.

del Carlo, Dawn I.; Bodner, George M.

2004-01-01

Although the literature on both academic dishonesty and scientific misconduct is extensive, research on academic dishonesty has focused on quizzes, exams, and papers, with the virtual exclusion of the classroom laboratory. This study examined the distinctions undergraduate chemistry majors made between academic dishonesty in the classroom laboratory and scientific misconduct in the research laboratory. Across the spectrum of undergraduate chemistry courses, from the introductory course for first-semester chemistry majors to the capstone course in instrumental analysis, we noted that students believe the classroom lab is fundamentally different from a research or industrial lab. This difference is so significant that it carries over into students' perceptions of dishonesty in these two environments.

Introductory physics in biological context: An approach to improve introductory physics for life science students

NASA Astrophysics Data System (ADS)

Crouch, Catherine H.; Heller, Kenneth

2014-05-01

We describe restructuring the introductory physics for life science students (IPLS) course to better support these students in using physics to understand their chosen fields. Our courses teach physics using biologically rich contexts. Specifically, we use examples in which fundamental physics contributes significantly to understanding a biological system to make explicit the value of physics to the life sciences. This requires selecting the course content to reflect the topics most relevant to biology while maintaining the fundamental disciplinary structure of physics. In addition to stressing the importance of the fundamental principles of physics, an important goal is developing students' quantitative and problem solving skills. Our guiding pedagogical framework is the cognitive apprenticeship model, in which learning occurs most effectively when students can articulate why what they are learning matters to them. In this article, we describe our courses, summarize initial assessment data, and identify needs for future research.

Beyond performance metrics: Examining a decrease in students' physics self-efficacy through a social networks lens

NASA Astrophysics Data System (ADS)

Dou, Remy; Brewe, Eric; Zwolak, Justyna P.; Potvin, Geoff; Williams, Eric A.; Kramer, Laird H.

2016-12-01

The Modeling Instruction (MI) approach to introductory physics manifests significant increases in student conceptual understanding and attitudes toward physics. In light of these findings, we investigated changes in student self-efficacy while considering the construct's contribution to the career-decision making process. Students in the Fall 2014 and 2015 MI courses at Florida International University exhibited a decrease on each of the sources of self-efficacy and overall self-efficacy (N =147 ) as measured by the Sources of Self-Efficacy in Science Courses-Physics (SOSESC-P) survey. This held true regardless of student gender or ethnic group. Given the highly interactive nature of the MI course and the drops observed on the SOSESC-P, we chose to further explore students' changes in self-efficacy as a function of three centrality measures (i.e., relational positions in the classroom social network): inDegree, outDegree, and PageRank. We collected social network data by periodically asking students to list the names of peers with whom they had meaningful interactions. While controlling for PRE scores on the SOSESC-P, bootstrapped linear regressions revealed post-self-efficacy scores to be predicted by PageRank centrality. When disaggregated by the sources of self-efficacy, PageRank centrality was shown to be directly related to students' sense of mastery experiences. InDegree was associated with verbal persuasion experiences, and outDegree with both verbal persuasion and vicarious learning experiences. We posit that analysis of social networks in active learning classrooms helps to reveal nuances in self-efficacy development.

Conceptual question response times in Peer Instruction classrooms

NASA Astrophysics Data System (ADS)

Miller, Kelly; Lasry, Nathaniel; Lukoff, Brian; Schell, Julie; Mazur, Eric

2014-12-01

Classroom response systems are widely used in interactive teaching environments as a way to engage students by asking them questions. Previous research on the time taken by students to respond to conceptual questions has yielded insights on how students think and change conceptions. We measure the amount of time students take to respond to in-class, conceptual questions [ConcepTests (CTs)] in two introductory physics courses taught using Peer Instruction and use item response theory to determine the difficulty of the CTs. We examine response time differences between correct and incorrect answers both before and after the peer discussion for CTs of varying difficulty. We also determine the relationship between response time and student performance on a standardized test of incoming physics knowledge, precourse self-efficacy, and gender. Our data reveal three results of interest. First, response time for correct answers is significantly faster than for incorrect answers, both before and after peer discussion, especially for easy CTs. Second, students with greater incoming physics knowledge and higher self-efficacy respond faster in both rounds. Third, there is no gender difference in response rate after controlling for incoming physics knowledge scores, although males register significantly more attempts before committing to a final answer than do female students. These results provide insight into effective CT pacing during Peer Instruction. In particular, in order to maintain a pace that keeps everyone engaged, students should not be given too much time to respond. When around 80% of the answers are in, the ratio of correct to incorrect responses rapidly approaches levels indicating random guessing and instructors should close the poll.

Examining the Gender Gap in Introductory Physics

NASA Astrophysics Data System (ADS)

Kost, Lauren; Pollock, Steven; Finkelstein, Noah

2009-05-01

Our previous research[1] showed that despite the use of interactive engagement techniques in the introductory physics course, the gap in performance between males and females on a mechanics conceptual learning survey persisted from pre- to post-test, at our institution. Such findings were counter to previously published work[2]. Follow-up studies[3] identified correlations between student performance on the conceptual learning survey and students' prior physics and math knowledge and their incoming attitudes and beliefs about physics and learning physics. The results indicate that the gender gap at our institution is predominantly associated with differences in males' and females' previous physics and math knowledge, and attitudes and beliefs. Our current work extends these results in two ways: 1) we look at the gender gap in the second semester of the introductory sequence and find results similar to those in the first semester course and 2) we identify ways in which males and females differentially experience several aspects of the introductory course.

GETSI (Geodesy Tools for Societal Issues) is an NSF-funded partnership program between UNAVCO, Indiana University, Mt. San Antonio College, and the Science Education Resource Center (SERC). We present results from classroom testing and assessment of the GETSI Ice Mass and Sea Level Changes module that utilizes geodetic data to teach about ice sheet mass loss in introductory undergraduate courses. The module explores the interactions between global sea level rise, Greenland ice mass loss, and the response of the solid Earth. It brings together topics typically addressed in introductory Earth science courses (isostatic rebound, geologic measurements, and climate change) in a way that highlights the interconnectivity of the Earth system and the interpretation of geodetic data. The module was tested 3 times at 3 different institution types (R1 institution, comprehensive university, and community college), and formative and summative assessment data were obtained. We will provide an overview of the instructional materials, describe our teaching methods, and discuss how formative and summative assessment data assisted in revisions of the teaching materials and changes in our pedagogy during subsequent implementation of the module. We will also provide strategies for faculty who wish to incorporate the module into their curricula. Instructional materials, faculty and student resources, and implementation tips are freely available on the GETSI website.

Arion, D. N.; Crosby, K. M.; Murphy, E. A.

2000-09-01

Carthage College added inquiry-based case study activities to the traditional introductory physics laboratory. Student teams designed, constructed, and executed their own experiments to study real-world phenomena, through which they gained understanding both of physic principles and methods of physics research. Assessment results and student feedback through teacher evaluations indicate that these activities improved student attitudes about physics as well as their ability to solve physics problems relative to previous course offerings that did not include case study.

Implementing Inclusive Design for Learning in an introductory geology laboratory

Robert, G.; Merriman, J. D.; Ceylan, G. M.

2013-12-01

As an expansion of universal design for learning, IDL provides a framework for opening up and adapting classroom interaction systems, minimizing barriers through promoting perception, engagement, expression, and accommodation for diverse learners. We implemented an introductory-level laboratory for communicating the concept of magma viscosity using the guidelines and principles of IDL. We developed the lab as a mini-implementation project for an IDL course offered by the University of Missouri (MU) Graduate School. The laboratory was subsequently taught during the summer session of Principles of Geology in our Department of Geological Sciences. Traditional geology laboratories rely heavily on visual aids, either physical (rocks and minerals) or representative (idealized cartoons of processes, videos), with very few alternative representations and descriptions made available to the students. Our main focus for this new lab was to diversify the means of representation available to the students (and instructor) to make the lab as equitable and flexible as possible. We considered potential barriers to learning arising from the physical lab environment, from the means of representation, engagement and expression, and tried to minimize them upfront. We centred the laboratory on the link between volcano shape and viscosity as an applied way to convey that viscosity is the resistance to flow. The learning goal was to have the students observe that more viscous eruptives resulted in steeper-sided volcanoes through experimentation. Students built their own volcanoes by erupting lava (foods of various viscosities) onto the Earth's surface (a piece of sturdy cardboard with a hole for the 'vent') through a conduit (pastry bag). Such a hands on lab exercise allows students to gain a tactile and visual, i.e., physical representation of an abstract concept. This specific exercise was supported by other, more traditional, means of representation (e.g., lecture, videos, cartoons, 3D models, online resources, textbook) in lecture and lab. We will discuss the details of the design, the implementation experience, and the insights for lab improvement in future iterations. This exercise represents the initial steps toward (re)designing introductory geoscience labs to more effectively include diverse learners.

Escape the Black Hole of Lecturing: Put Collaborative Ranking Tasks on Your Event Horizon

At the University of Arizona, we have been developing and testing a new type of introductory astronomy curriculum material called Ranking Tasks. Ranking Tasks are a form of conceptual exercise that presents students with four to six physical situations, usually by pictures or diagrams, and asks students to rank order the situations based on some resulting effect. Our study developed design guidelines for Ranking Tasks based on learning theory and classroom pilot studies. Our research questions were: Do in-class collaborative Ranking Task exercises result in student conceptual gains when used in conjunction with traditional lecture-based instruction? And are these gains sufficient to justify implementing them into the astronomy classroom? We conducted a single-group repeated measures experiment across eight core introductory astronomy topics with 250 students at the University of Arizona in the Fall of 2004. The study found that traditional lecture-based instruction alone produced statistically significant gains - raising test scores to 61% post-lecture from 32% on the pretest. While significant, we find these gains to be unsatisfactory from a teaching and learning perspective. The study data shows that adding a collaborative learning component to the class structured around Ranking Task exercises helped students achieve statistically significant gains - with post-Ranking Task scores over the eight astronomy topic rising to 77%. Interestingly, we found that the normalized gain from the Ranking Tasks was equal to the entire previous gain from traditional instruction. Further analysis of the data revealed that Ranking Tasks equally benefited both genders; they also equally benefited both high and low-scoring median groups based on their pretest scores. Based on these results, we conclude that adding collaborative Ranking Task exercises to traditional lecture-based instruction can significantly improve student conceptual understanding of core topics in astronomy.

Gender Differences in Introductory University Physics Performance: The Influence of High School Physics Preparation and Affect

NASA Astrophysics Data System (ADS)

Hazari, Zahra

2006-12-01

The attrition of females studying physics after high school has been a continuing concern for the physics education community. If females are well prepared, feel confident, and do well in introductory college physics, they may be inclined to study physics further. This quantitative study uses HLM to identify factors from high school physics preparation (content, pedagogy, and assessment) and the affective domain that predict female and male performance in introductory college physics. The study includes controls for student demographic and academic background characteristics, and the final dataset consists of 1973 surveys from 54 introductory college physics classes. The results highlight high school physics and affective experiences that differentially predict female and male performance. These experiences include: learning requirements, computer graphing/analysis, long written problems, everyday world examples, community projects cumulative tests/quizzes, father's encouragement, family's belief that science leads to a better career, and the length of time students believe that high school physics would help in university physics. There were also experiences that similarly predict female and male performance. The results paint a dynamic picture of the factors from high school physics and the affective domain that influence the future physics performance of females and males. The implication is that there are many aspects to the teaching of physics in high school that, although widely used and thought to be effective, need reform in their implementation in order to be fully beneficial to females and/or males in college.

First order error corrections in common introductory physics experiments

NASA Astrophysics Data System (ADS)

Beckey, Jacob; Baker, Andrew; Aravind, Vasudeva; Clarion Team

As a part of introductory physics courses, students perform different standard lab experiments. Almost all of these experiments are prone to errors owing to factors like friction, misalignment of equipment, air drag, etc. Usually these types of errors are ignored by students and not much thought is paid to the source of these errors. However, paying attention to these factors that give rise to errors help students make better physics models and understand physical phenomena behind experiments in more detail. In this work, we explore common causes of errors in introductory physics experiment and suggest changes that will mitigate the errors, or suggest models that take the sources of these errors into consideration. This work helps students build better and refined physical models and understand physics concepts in greater detail. We thank Clarion University undergraduate student grant for financial support involving this project.

MAUVE: A New Strategy for Solving and Grading Physics Problems

NASA Astrophysics Data System (ADS)

Hill, Nicole Breanne

2016-05-01

MAUVE (magnitude, answer, units, variables, and equations) is a framework and rubric to help students and teachers through the process of clearly solving and assessing solutions to introductory physics problems. Success in introductory physics often derives from an understanding of units, a command over dimensional analysis, and good bookkeeping. I developed MAUVE for an introductory-level environmental physics course as an easy-to-remember checklist to help students construct organized and thoughtful solutions to physics problems. Environmental physics is a core physics course for environmental and sustainability science (ESS) majors that teaches principles of radiation, thermodynamics, and mechanics within the context of the environment and sustainable energy systems. ESS student concentrations include environmental biology, applied ecology, biogeochemistry, and natural resources. The MAUVE rubric, inspired by nature, has encouraged my students to produce legible and tactical work, and has significantly clarified the grading process.

Looking for radio waves with a simple radio wave detector

NASA Astrophysics Data System (ADS)

Sugimoto (Stray Cats), Norihiro

2011-11-01

I created a simple device that can detect radio waves in a classroom. In physics classes I tell students that we live in a sea of radio waves. They come from TV, radio, and cell phone signals as well as other sources. Students don't realize this because those electromagnetic waves are invisible. So, I wondered if I could come up with a way to detect the waves and help students to understand them better. Electromagnetic wave meters, which measure intensity of radio waves quantitatively, are commercially available. However, to students most of these are black boxes, and at the introductory level it is more effective to detect radio waves in a simpler way. This paper describes my device and how I have used it in my classes.

Diversity of faculty practice in workshop classrooms

NASA Astrophysics Data System (ADS)

Franklin, Scott V.; Chapman, Tricia

2013-01-01

We present a temporally fine-grained characterization of faculty practice in workshop-style introductory physics courses. Practice is binned in five minute intervals and coded through two complementary observational protocols: the Reform Teaching Observation Protocol provides a summative assessment of fidelity to reform-teaching principles, while the Teaching Dimensions Observation Protocol records direct practice. We find that the TDOP's direct coding of practice explains nuances in the holistic RTOP score, with higher RTOP scores corresponding to less lecture, but not necessarily more student-directed activities. Despite using similar materials, faculty show significant differences in practice that manifests in both TDOP and RTOP scores. We also find a significant dependence of practice on course subject reflected in both RTOP and TDOP scores, with Electricity & Magnetism using more instructor-centered practices (lecture, illustration, etc.) than Mechanics courses.

Students' network integration vs. persistence in introductory physics courses

NASA Astrophysics Data System (ADS)

Zwolak, Justyna; Brewe, Eric

2017-01-01

Society is constantly in flux, which demands the continuous development of our educational system to meet new challenges and impart the appropriate knowledge/skills to students. In order to improve student learning, among other things, the way we are teaching has significantly changed over the past few decades. We are moving away from traditional, lecture-based teaching towards more interactive, engagement-based strategies. A current, major challenge for universities is to increase student retention. While students' academic and social integration into an institution seems to be vital for student retention, research on the effect of interpersonal interactions is rare. I use of network analysis to investigate academic and social experiences of students in and beyond the classroom. In particular, there is a compelling case that transformed physics classes, such as Modeling Instruction (MI), promote persistence by the creation of learning communities that support the integration of students into the university. I will discuss recent results on pattern development in networks of MI students' interactions throughout the semester, as well as the effect of students' position within the network on their persistence in physics.

Assessing the Impacts of a Hybrid ``Flipped'' Approach to University Physics.

NASA Astrophysics Data System (ADS)

Hughes, Chris; Paulson, Scott

2015-03-01

Over the course of several years, the physics faculty at James Madison University has been gradually reforming the introductory calculus-based physics sequence to a hybrid model using a ``flipped classroom'' approach. The content traditionally delivered during lecture was divided into approximately 150 short (5-10 minute) videos. For homework, students are assigned 3-5 videos to watch before each class session. These assignments are combined with in-class activities including gouger problem solving and the tutorials developed by the University of Washington group to provide the students with focused guidance on concepts and skills that students traditionally have left our classes not having mastered. For the fall semester course on mechanics, the Force Concept Inventory (FCI) was used to evaluate student outcomes. For the spring semester course on E&M and optics, the Conceptual Survey of Electricity and Magnetism (CSEM) was used. Student reaction to the course structure was generally positive though there were some complaints in the student evaluations at the end of each semester. However, a positive impact on student outcomes was observed based on the Hake gains on the FCI.

Addressing Gender Disparity in Introductory Physics Courses: Are existing reforms enough?

NASA Astrophysics Data System (ADS)

Finkelstein, Noah; Pollock, Steven; Dubson, Michael

2007-03-01

Previously researchers have reported that by transforming teaching practices in introductory physics, it is possible to eliminate the disparity in achievement of males and females on measures of conceptual learning. [1] We follow-up on the studies of the original researchers by comparing achievement of male and female students on measures of conceptual learning in the introductory physics courses at a large public research university. Just as the original authors find, we observe that reform teaching practices, such as the use of Peer Instruction [2] increase the learning gains of all students in introductory physics. Additionally, we observe a significant reduction in this gender gap in learning gains in some but not all of our transformed courses. Notably, however, the gender gap does not completely disappear in any of our courses. In addition to discussing learning gains, we analyze shifts in student beliefs [3] and examine correlations between student beliefs and learning gains. [1] Lorenzo, M et al. (2006).Am. J.

Lo Presto, Michael C.

2003-07-01

With the aid of microcomputer hardware and software for the introductory physics laboratory, I have developed several experiments dealing with the properties of brass musical instruments that could be used when covering sound anywhere from an introductory physics laboratory to a course in musical acoustics, or even independent studies. The results of these experiments demonstrate in a quantitative fashion the effects of the mouthpiece and bell on the frequencies of the sound waves and thus the musical pitches produced. Most introductory sources only discuss these effects qualitatively.

Replicating effective pedagogical approaches from introductory physics to improve student learning of quantum mechanics

NASA Astrophysics Data System (ADS)

Sayer, Ryan Thomas

Upper-level undergraduate students entering a quantum mechanics (QM) course are in many ways similar to students entering an introductory physics course. Numerous studies have investigated the difficulties that novices face in introductory physics as well as the pedagogical approaches that are effective in helping them overcome those difficulties. My research focuses on replicating effective approaches and instructional strategies used in introductory physics courses to help advanced students in an upper-level QM course. I have investigated the use of Just-in-time Teaching (JiTT) and peer discussion involving clicker questions in an upper-level quantum mechanics course. The JiTT approach including peer discussions was effective in helping students overcome their difficulties and improve their understanding of QM concepts. Learning tools, such as a Quantum Interactive Learning Tutorial (QuILT) based on the Doubleslit Experiment (DSE) which I helped develop, have been successful in helping upper-level undergraduate students improve their understanding of QM. Many students have also demonstrated the ability to transfer knowledge from a QuILT based on the Mach-Zehnder interferometer while working on the DSE QuILT. In addition, I have been involved in implementing research-based activities during our semester-long professional development course for teaching assistants (TAs). In one intervention, TAs were asked to grade student solutions to introductory physics problems first using their choice of method, then again using a rubric designed to promote effective problem-solving approaches, then once more at the end of the semester using their choice of method. This intervention found that many TAs have ingrained beliefs about the purposes of grading which include placing the burden of proof on the instructor as well as a belief that grading cannot serve as a formative assessment. I also compared TAs grading practices and considerations when grading student solutions to QM problems versus when grading student solutions to introductory physics. Many TAs penalized students for not explicating the problem solving process more often in the QM context than in the introductory physics context. The implications of these interventions for promoting student learning in QM are discussed.

Transversality of electromagnetic waves in the calculus-based introductory physics course

NASA Astrophysics Data System (ADS)

Burko, Lior M.

2008-11-01

Introductory calculus-based physics textbooks state that electromagnetic waves are transverse and list many of their properties, but most such textbooks do not bring forth arguments why this is so. Both physical and theoretical arguments are at a level appropriate for students of courses based on such books, and could be readily used by instructors of such courses. Here, we discuss two physical arguments (based on polarization experiments and on lack of monopole electromagnetic radiation) and the full argument for the transversality of (plane) electromagnetic waves based on the integral Maxwell equations. We also show, at a level appropriate for the introductory course, why the electric and magnetic fields in a wave are in phase and the relation of their magnitudes.

Kinematics Card Sort Activity: Insight into Students' Thinking

NASA Astrophysics Data System (ADS)

Berryhill, Erin; Herrington, Deborah; Oliver, Keith

2016-12-01

Kinematics is a topic students are unknowingly aware of well before entering the physics classroom. Students observe motion on a daily basis. They are constantly interpreting and making sense of their observations, unintentionally building their own understanding of kinematics before receiving any formal instruction. Unfortunately, when students take their prior conceptions to understand a new situation, they often do so in a way that inaccurately connects their learning. We were motivated to identify strategies to help our students make accurate connections to their prior knowledge and understand kinematics at a deeper level. To do this, we integrated a formative assessment card sort into a kinematic graphing unit within an introductory high school physics course. Throughout the activities, we required students to document and reflect upon their thinking. This allowed their learning to build upon their own previously held conceptual understanding, which provided an avenue for cognitive growth. By taking a more direct approach to eliciting student reasoning, we hoped to improve student learning and guide our assessment of their learning.

Alpha Particle Induced X-ray Emission in the Classroom

We report on an experimental demonstration in an introductory modern physics course to elucidate the X-ray line spectra, and how they arise from transitions of electrons to inner shells. We seek to determine the effect of limited use of an interactive component as a supplement to a traditional lecture, and how it would improve the student achievement. In this preliminary study the students were exposed to traditional lectures on X-ray production and Bohr's model, they then were given a homework on the abc of X-ray spectra, after which they were given a pre-test on the materials, followed by an in-classmore » demonstration, and a final post-exam. The gain, as measured from pre- to post-exams appears to remark the differences in how students approached the subject before and after the use of the demonstration. This initial study shows the validity of in-class demonstrations as teaching tools and opens a wide new area of research in modern physics teaching.« less

Verification of causal influences of reasoning skills and epistemology on physics conceptual learning

NASA Astrophysics Data System (ADS)

Ding, Lin

2014-12-01

This study seeks to test the causal influences of reasoning skills and epistemologies on student conceptual learning in physics. A causal model, integrating multiple variables that were investigated separately in the prior literature, is proposed and tested through path analysis. These variables include student preinstructional reasoning skills measured by the Classroom Test of Scientific Reasoning, pre- and postepistemological views measured by the Colorado Learning Attitudes about Science Survey, and pre- and postperformance on Newtonian concepts measured by the Force Concept Inventory. Students from a traditionally taught calculus-based introductory mechanics course at a research university participated in the study. Results largely support the postulated causal model and reveal strong influences of reasoning skills and preinstructional epistemology on student conceptual learning gains. Interestingly enough, postinstructional epistemology does not appear to have a significant influence on student learning gains. Moreover, pre- and postinstructional epistemology, although barely different from each other on average, have little causal connection between them.

Mathematization in introductory physics

NASA Astrophysics Data System (ADS)

Brahmia, Suzanne M.

Mathematization is central to STEM disciplines as a cornerstone of the quantitative reasoning that characterizes these fields. Introductory physics is required for most STEM majors in part so that students develop expert-like mathematization. This dissertation describes coordinated research and curriculum development for strengthening mathematization in introductory physics; it blends scholarship in physics and mathematics education in the form of three papers. The first paper explores mathematization in the context of physics, and makes an original contribution to the measurement of physics students' struggle to mathematize. Instructors naturally assume students have a conceptual mastery of algebra before embarking on a college physics course because these students are enrolled in math courses beyond algebra. This paper provides evidence that refutes the validity of this assumption and categorizes some of the barriers students commonly encounter with quantification and representing ideas symbolically. The second paper develops a model of instruction that can help students progress from their starting points to their instructor's desired endpoints. Instructors recognize that the introductory physics course introduces new ideas at an astonishing rate. More than most physicists realize, however, the way that mathematics is used in the course is foreign to a large portion of class. This paper puts forth an instructional model that can move all students toward better quantitative and physical reasoning, despite the substantial variability of those students' initial states. The third paper describes the design and testing of curricular materials that foster mathematical creativity to prepare students to better understand physics reasoning. Few students enter introductory physics with experience generating equations in response to specific challenges involving unfamiliar quantities and units, yet this generative use of mathematics is typical of the thinking involved in doing physics. It contrasts with their more common experience with mathematics as the practice of specified procedures to improve efficiency. This paper describes new curricular materials based on invention instruction provide students with opportunities to generate mathematical relationships in physics, and the paper presents preliminary evidence of the effectiveness of this method with mathematically underprepared engineering students.

Testing The Scale-up Approach To Introductory Astronomy

NASA Astrophysics Data System (ADS)

Kregenow, Julia M.; Keller, L.; Rogers, M.; Romero, D.

2008-09-01

Ithaca College physics department has begun transforming our general education astronomy courses into hands-on, active-learning courses from the previous lecture-based format. We are using the SCALE-UP model (Student Centered Activities for Large Enrollment University Programs) pioneered at North Carolina State University. Expanding on the successes of Studio Physics (developed at RPI), which exchanges traditionally separate lecture/recitation/ laboratory sessions for one dynamic, active-learning environment for approximately 40 students, SCALE-UP extends this model to accommodate 100+ students by using large round tables creating naturally smaller groups of students. Classes meet three times per week with each class blending lecture, hands-on activities, group problem solving, and the use of student polling devices. We are testing whether this mode of teaching astronomy will lead to a better understanding of astronomy and the nature of science. Applying this approach in both the SCALE-UP classroom (90 students) and a traditional lecture classroom (45 students) in spring 2008, we report on our early results and lessons learned after one semester. We also discuss some of our lingering implementation questions and issues, such as: whether to use the same or different instructor in two parallel sections, requiring textbook reading, reading quizzes, on-line homework and activities, how much math to include, development of hands-on activities, and culling the typically overpacked intro astronomy syllabus.

A Framework for Understanding the Patterns of Student Difficulties in Quantum Mechanics

NASA Astrophysics Data System (ADS)

Singh, Chandralekha

2015-04-01

Compared with introductory physics, relatively little is known about the development of expertise in advanced physics courses, especially in the case of quantum mechanics. We describe a theoretical framework for understanding the patterns of student reasoning difficulties and how students develop expertise in quantum mechanics. The framework posits that the challenges many students face in developing expertise in quantum mechanics are analogous to the challenges introductory students face in developing expertise in introductory classical mechanics. This framework incorporates the effects of diversity in students' prior preparation, goals and motivation for taking upper-level physics courses in general as well as the ``paradigm shift'' from classical mechanics to quantum mechanics. The framework is based on empirical investigations demonstrating that the patterns of reasoning, problem-solving, and self-monitoring difficulties in quantum mechanics bear a striking resemblance to those found in introductory classical mechanics. Examples from research in quantum mechanics and introductory classical mechanics will be discussed to illustrate how the patterns of difficulties are analogous as students learn to unpack the respective principles and grasp the formalism in each knowledge domain during the development of expertise. Embracing such a theoretical framework and contemplating the parallels between the difficulties in these two knowledge domains can enable researchers to leverage the extensive literature for introductory physics education research to guide the design of teaching and learning tools for helping students develop expertise in quantum mechanics.

Characterizing, modeling, and addressing gender disparities in introductory college physics

NASA Astrophysics Data System (ADS)

Kost-Smith, Lauren Elizabeth

2011-12-01

The underrepresentation and underperformance of females in physics has been well documented and has long concerned policy-makers, educators, and the physics community. In this thesis, we focus on gender disparities in the first- and second-semester introductory, calculus-based physics courses at the University of Colorado. Success in these courses is critical for future study and careers in physics (and other sciences). Using data gathered from roughly 10,000 undergraduate students, we identify and model gender differences in the introductory physics courses in three areas: student performance, retention, and psychological factors. We observe gender differences on several measures in the introductory physics courses: females are less likely to take a high school physics course than males and have lower standardized mathematics test scores; males outscore females on both pre- and post-course conceptual physics surveys and in-class exams; and males have more expert-like attitudes and beliefs about physics than females. These background differences of males and females account for 60% to 70% of the gender gap that we observe on a post-course survey of conceptual physics understanding. In analyzing underlying psychological factors of learning, we find that female students report lower self-confidence related to succeeding in the introductory courses (self-efficacy) and are less likely to report seeing themselves as a "physics person". Students' self-efficacy beliefs are significant predictors of their performance, even when measures of physics and mathematics background are controlled, and account for an additional 10% of the gender gap. Informed by results from these studies, we implemented and tested a psychological, self-affirmation intervention aimed at enhancing female students' performance in Physics 1. Self-affirmation reduced the gender gap in performance on both in-class exams and the post-course conceptual physics survey. Further, the benefit of the self-affirmation was strongest for females who endorsed the stereotype that men do better than women in physics. The findings of this thesis suggest that there are multiple factors that contribute to the underperformance of females in physics. Establishing this model of gender differences is a first step towards increasing females' participation and performance in physics, and can be used to guide future interventions to address the disparities.

Using isomorphic problems to learn introductory physics

NASA Astrophysics Data System (ADS)

Lin, Shih-Yin; Singh, Chandralekha

2011-12-01

In this study, we examine introductory physics students’ ability to perform analogical reasoning between two isomorphic problems which employ the same underlying physics principles but have different surface features. Three hundred sixty-two students from a calculus-based and an algebra-based introductory physics course were given a quiz in the recitation in which they had to first learn from a solved problem provided and take advantage of what they learned from it to solve another problem (which we call the quiz problem) which was isomorphic. Previous research suggests that the multiple-concept quiz problem is challenging for introductory students. Students in different recitation classes received different interventions in order to help them discern and exploit the underlying similarities of the isomorphic solved and quiz problems. We also conducted think-aloud interviews with four introductory students in order to understand in depth the difficulties they had and explore strategies to provide better scaffolding. We found that most students were able to learn from the solved problem to some extent with the scaffolding provided and invoke the relevant principles in the quiz problem. However, they were not necessarily able to apply the principles correctly. Research suggests that more scaffolding is needed to help students in applying these principles appropriately. We outline a few possible strategies for future investigation.

Toward equity through participation in Modeling Instruction in introductory university physics

NASA Astrophysics Data System (ADS)

Brewe, Eric; Sawtelle, Vashti; Kramer, Laird H.; O'Brien, George E.; Rodriguez, Idaykis; Pamelá, Priscilla

2010-06-01

We report the results of a five year evaluation of the reform of introductory calculus-based physics by implementation of Modeling Instruction (MI) at Florida International University (FIU), a Hispanic-serving institution. MI is described in the context of FIU’s overall effort to enhance student participation in physics and science broadly. Our analysis of MI from a “participationist” perspective on learning identifies aspects of MI including conceptually based instruction, culturally sensitive instruction, and cooperative group learning, which are consistent with research on supporting equitable learning and participation by students historically under-represented in physics (i.e., Black, Hispanic, women). This study uses markers of conceptual understanding as measured by the Force Concept Inventory (FCI) and odds of success as measured by the ratio of students completing introductory physics and earning a passing grade (i.e., C- or better) by students historically under-represented in physics to reflect equity and participation in introductory physics. FCI pre and post scores for students in MI are compared with lecture-format taught students. Modeling Instruction students outperform students taught in lecture-format classes on post instruction FCI (61.9% vs 47.9%, p<0.001 ), where these benefits are seen across both ethnic and gender comparisons. In addition, we report that the odds of success in MI are 6.73 times greater than in lecture instruction. Both odds of success and FCI scores within Modeling Instruction are further disaggregated by ethnicity and by gender to address the question of equity within the treatment. The results of this disaggregation indicate that although ethnically under-represented students enter with lower overall conceptual understanding scores, the gap is not widened during introductory physics but instead is maintained, and the odds of success for under-represented students is not different from majority students. Women, similarly enter with scores indicating lower conceptual understanding, and over the course of MI this understanding gap increases, yet we do not find differences in the odds of success between men and women. Contrasting these results with the participationist view on learning indicates a movement toward greater equity in introductory physics but also indicates that the instructional environment can be improved.

Beyond the Biology: A Systematic Investigation of Noncontent Instructor Talk in an Introductory Biology Course

PubMed Central

Seidel, Shannon B.; Reggi, Amanda L.; Schinske, Jeffrey N.; Burrus, Laura W.; Tanner, Kimberly D.

2015-01-01

Instructors create classroom environments that have the potential to impact learning by affecting student motivation, resistance, and self-efficacy. However, despite the critical importance of the learning environment in increasing conceptual understanding, little research has investigated what instructors say and do to create learning environments in college biology classrooms. We systematically investigated the language used by instructors that does not directly relate to course content and defined the construct of Instructor Talk. Transcripts were generated from a semester-long, cotaught introductory biology course (n = 270 students). Transcripts were analyzed using a grounded theory approach to identify emergent categories of Instructor Talk. The five emergent categories from analysis of more than 600 quotes were, in order of prevalence, 1) Building the Instructor/Student Relationship, 2) Establishing Classroom Culture, 3) Explaining Pedagogical Choices, 4) Sharing Personal Experiences, and 5) Unmasking Science. Instances of Instructor Talk were present in every class session analyzed and ranged from six to 68 quotes per session. The Instructor Talk framework is a novel research variable that could yield insights into instructor effectiveness, origins of student resistance, and methods for overcoming stereotype threat. Additionally, it holds promise in professional development settings to assist instructors in reflecting on the learning environments they create. PMID:26582237

Efficacy of a Meiosis Learning Module Developed for the Virtual Cell Animation Collection

PubMed Central

Goff, Eric E.; Reindl, Katie M.; Johnson, Christina; McClean, Phillip; Offerdahl, Erika G.; Schroeder, Noah L.; White, Alan R.

2017-01-01

Recent reports calling for change in undergraduate biology education have resulted in the redesign of many introductory biology courses. Reports on one common change to course structure, the active-learning environment, have placed an emphasis on student preparation, noting that the positive outcomes of active learning in the classroom depend greatly on how well the student prepares before class. As a possible preparatory resource, we test the efficacy of a learning module developed for the Virtual Cell Animation Collection. This module presents the concepts of meiosis in an interactive, dynamic environment that has previously been shown to facilitate learning in introductory biology students. Participants (n = 534) were enrolled in an introductory biology course and were presented the concepts of meiosis in one of two treatments: the interactive-learning module or a traditional lecture session. Analysis of student achievement shows that students who viewed the learning module as their only means of conceptual presentation scored significantly higher (d = 0.40, p < 0.001) than students who only attended a traditional lecture on the topic. Our results show the animation-based learning module effectively conveyed meiosis conceptual understanding, which suggests that it may facilitate student learning outside the classroom. Moreover, these results have implications for instructors seeking to expand their arsenal of tools for “flipping” undergraduate biology courses. PMID:28188282

Taking "The Math You Need When You Need It" Modules Beyond Introductory Geology Courses

NASA Astrophysics Data System (ADS)

Baer, E. M.; Wenner, J. M.; Burn, H. E.

2012-12-01

"The Math You Need, When You Need It" (TMYN) modules are finding use well beyond the courses for which they were originally written. However, faculty survey responses indicate that the modules are used in similar ways, suggesting that the overall design of the modules is effective. TMYN modules are online resources designed to help students develop quantitative skills in conjunction with introductory geology courses. Since 2010, 29 faculty members at 26 institutions used these asynchronous resources at in 68 different courses nationwide, impacting about 3000 students. After each use of the modules, instructors responded to a survey about their use of the modules and the impact on each course and student cohort. Of the 29 instructors, 16 responded with a total of 36 implementations, a 52% response rate. Survey responses indicate use of TMYN modules in classes well beyond their original design. The modules were originally designed for students in introductory geology classes, especially those targeted at non-geoscience majors. Sixty-nine percent (22/32) of TMYN courses included introductory geology courses such as Physical Geology, Earth System Science and Environmental Geology. The remainder of courses included multiple uses in oceanography and meteorology courses and more specialized geoscience courses such as geomorphology, structural geology and hydrology. Surveys suggest that only 63% of courses that used TMYN (20/32) were targeted to students in general education courses. Nine percent (3/32) of courses were targeted to STEM majors and 19% (6/32) were specifically targeted to geoscience majors, including upper-level courses. Despite the wide variety of institutions, instructors, classes, and student educational goals, faculty incorporated the modules into their curriculum in as originally designed, indicating that the overall design of the modules is effective. Twenty-two respondents indicate that modules were assigned immediately prior to using a skill in the classroom (either in lab exercises or a lecture period). Almost all instructors employed pre- and posttests to gauge learning. More than ¾ of survey respondents introduced the modules within the first week of class. In all but one instance, students were instructed to complete an online quiz immediately after working through the online modules and most (77%) designed these post-module quizzes as formative assessments allowing at least 3 attempts. The grades on these modules contributed to students' grades but were relatively low stakes with 88% reporting that the modules contributed to less than 10% of a student's course grade. Given the use beyond the introductory geology classroom and the similarity of the use of these modules in a wide variety of courses, it appears that the design of the modules is sound. However, previous studies have indicated that mathematical skills are not easily transferred (e.g. Bassok. and Holyoak, 1989) suggesting the adaptation of the modules for use outside the geosciences.

Integrating writing research with curricular development in large-enrollment introductory physics

NASA Astrophysics Data System (ADS)

Demaree, Dedra

2008-05-01

Multiple research projects have been undertaken as part of an ongoing study to develop methods to do quantitative assessment of writing to learn within physics. The ability to make use of writing to learn at first glance appears limited in large-enrollment courses due to the time-intensive nature of essay writing and grading. However, effective ways to implement writing are quite possible. One study that will be discussed required students to do textbook summary writing in introductory physics in the 2007 spring semester of the ``Foundation Physics Course'' at the University of Cape Town. This course is a component of the special access program which contains mostly second language English speakers. Another use of writing will be reported that is currently being used in the introductory physics course at Oregon State University as a way to enhance problem solving. This project is also aimed at scaffolding students toward goals in our upper division courses. This talk will report on some of what we know about writing to learn, how we are working to improve ways to study it quantitatively, and how we are incorporating some aspects of it in accessible ways in large-enrollment introductory courses.

Persistence of physics and engineering students via peer mentoring, active learning, and intentional advising

NASA Astrophysics Data System (ADS)

McCavit, K.; Zellner, N. E. B.

2016-11-01

Albion College, a private, undergraduate-only, liberal arts college in Michigan, USA, has developed and implemented a low-cost peer-mentoring programme that blends personal and academic support to help students achieve academic success in the introductory courses required for the Physics Major or the Dual-Degree Program in Engineering. This enhanced mentoring programme provides much-needed assistance for undergraduate students to master introductory physics and mathematics coursework, to normalise the struggle of learning hard material, and to accept their identity as physics or engineering students (among other goals). Importantly, this programme has increased retention among entering science, technology, engineering and mathematics students at Albion College as they move through the introductory classes, as shown by a 20% increase in retention from first-semester to third-semester physics courses compared to years when this programme was not in place.

Framework for understanding the patterns of student difficulties in quantum mechanics

NASA Astrophysics Data System (ADS)

Marshman, Emily; Singh, Chandralekha

2015-12-01

[This paper is part of the Focused Collection on Upper Division Physics Courses.] Compared with introductory physics, relatively little is known about the development of expertise in advanced physics courses, especially in the case of quantum mechanics. Here, we describe a framework for understanding the patterns of student reasoning difficulties and how students develop expertise in quantum mechanics. The framework posits that the challenges many students face in developing expertise in quantum mechanics are analogous to the challenges introductory students face in developing expertise in introductory classical mechanics. This framework incorporates both the effects of diversity in upper-level students' prior preparation, goals, and motivation in general (i.e., the facts that even in upper-level courses, students may be inadequately prepared, have unclear goals, and have insufficient motivation to excel) as well as the "paradigm shift" from classical mechanics to quantum mechanics. The framework is based on empirical investigations demonstrating that the patterns of reasoning, problem-solving, and self-monitoring difficulties in quantum mechanics bear a striking resemblance to those found in introductory classical mechanics. Examples from research in quantum mechanics and introductory classical mechanics are discussed to illustrate how the patterns of difficulties are analogous as students learn to unpack the respective principles and grasp the formalism in each knowledge domain during the development of expertise. Embracing such a framework and contemplating the parallels between the difficulties in these two knowledge domains can enable researchers to leverage the extensive literature for introductory physics education research to guide the design of teaching and learning tools for helping students develop expertise in quantum mechanics.

Efforts to Recruit Secondary STEM Teachers at Columbus State University

NASA Astrophysics Data System (ADS)

Webster, Zodiac T.; MaSST Preparation Council

2006-12-01

Physics as a discipline is not alone in having difficulty finding qualified teachers. Under-qualified teachers are present in high school Mathematics, Chemistry, Biology, and Earth-science classrooms as well. Columbus State University (CSU) has formed the Mathematics and Science Secondary Teachers (MaSST) Preparation Council to recruit more majors into our existing secondary teaching programs: Mathematics, Biology, Chemistry, and Geology. College of Education and College of Science faculty are working together to create a higher profile for these majors at our institution within the state of Georgia. In addition, we are planning an aggressive campaign to recruit from within by implementing a peer-tutoring program using outstanding students who have completed introductory math and science courses. Our group’s organization and initiatives can serve as a model for other institutions concerned about recruiting more high-school teachers.

How gender and reformed introductory physics impacts student success in advanced physics courses and continuation in the physics major

NASA Astrophysics Data System (ADS)

Rodriguez, Idaykis; Potvin, Geoff; Kramer, Laird H.

2016-12-01

[This paper is part of the Focused Collection on Gender in Physics.] Active-learning approaches to teaching introductory physics have been found to improve student learning and affective gains on short-term outcomes [S. Freeman et al., Proc. Natl. Acad. Sci. U.S.A. 111, 8410 (2014)]; however, whether or not the benefits of active learning impact women to the same degree as men has been a point of concern [A. Madsen, S. B. McKagan, and E. C. Sayre, Phys. Rev. ST Phys. Educ. Res. 9, 020121 (2013)]. Further, the long-term impacts of active-learning experiences are also understudied. At Florida International University, a Hispanic-majority institution, we have implemented Modeling Instruction (MI) and the Integrated Science Learning Environment (ISLE) in introductory physics classes for the past decade. In this empirical paper, we report on a longitudinal investigation of student performance and persistence in upper level physics courses after having previously experienced MI or ISLE in their introductory physics courses, and disaggregate students by gender. Using survival analysis methods, we find women who declare physics as a major are more likely than men to graduate with a physics degree. Women are also just as likely as men to pass through the upper division courses, with the highest failure risk for both men and women occurring in the first semester of upper-division course taking. These results reinforce the need to expand considerations of performance outcomes to be longitudinal to measure the effectiveness of the entire physics experience.

Sixteen years of collaborative learning through active sense-making in physics (CLASP) at UC Davis

NASA Astrophysics Data System (ADS)

Potter, Wendell; Webb, David; Paul, Cassandra; West, Emily; Bowen, Mark; Weiss, Brenda; Coleman, Lawrence; De Leone, Charles

2014-02-01

This paper describes our large reformed introductory physics course at UC Davis, which bioscience students have been taking since 1996. The central feature of this course is a focus on sense-making by the students during the 5 h per week discussion/labs in which the students take part in activities emphasizing peer-peer discussions, argumentation, and presentations of ideas. The course differs in many fundamental ways from traditionally taught introductory physics courses. After discussing the unique features of CLASP and its implementation at UC Davis, various student outcome measures are presented that show increased performance by students who took the CLASP course compared to students who took a traditionally taught introductory physics course. Measures we use include upper-division GPAs, MCAT scores, FCI gains, and MPEX-II scores.

The Solar-Terrestrial Environment

NASA Astrophysics Data System (ADS)

Hargreaves, John Keith

1995-05-01

The book begins with three introductory chapters that provide some basic physics and explain the principles of physical investigation. The principal material contained in the main part of the book covers the neutral and ionized upper atmosphere, the magnetosphere, and structures, dynamics, disturbances, and irregularities. The concluding chapter deals with technological applications. The account is introductory, at a level suitable for readers with a basic background in engineering or physics. The intent is to present basic concepts, and for that reason, the mathematical treatment is not complex. SI units are given throughout, with helpful notes on cgs units where these are likely to be encountered in the research literature. This book is suitable for advanced undergraduate and graduate students who are taking introductory courses on upper atmospheric, ionospheric, or magnetospheric physics. This is a successor to The Upper Atmosphere and Solar-Terrestrial Relations, published in 1979.

Fourier Analysis in Introductory Physics

NASA Astrophysics Data System (ADS)

Huggins, Elisha

2007-01-01

In an after-dinner talk at the fall 2005 meeting of the New England chapter of the AAPT, Professor Robert Arns drew an analogy between classical physics and Classic Coke. To generations of physics teachers and textbook writers, classical physics was the real thing. Modern physics, which in introductory textbooks "appears in one or more extra chapters at the end of the book, … is a divertimento that we might get to if time permits." Modern physics is more like vanilla or lime Coke, probably a fad, while "Classic Coke is part of your life; you do not have to think about it twice."

Cognitive development in introductory physics: A research-based approach to curriculum reform

NASA Astrophysics Data System (ADS)

Teodorescu, Raluca Elena

This project describes the research on a classification of physics problems in the context of introductory physics courses. This classification, called the Taxonomy of Introductory Physics Problems (TIPP), relates physics problems to the cognitive processes required to solve them. TIPP was created for designing and clarifying educational objectives, for developing assessments that can evaluate individual component processes of the problem-solving process, and for guiding curriculum design in introductory physics courses, specifically within the context of a "thinking-skills" curriculum. TIPP relies on the following resources: (1) cognitive research findings adopted by physics education research, (2) expert-novice research discoveries acknowledged by physics education research, (3) an educational psychology taxonomy for educational objectives, and (4) various collections of physics problems created by physics education researchers or developed by textbook authors. TIPP was used in the years 2006--2008 to reform the first semester of the introductory algebra-based physics course (called Phys 11) at The George Washington University. The reform sought to transform our curriculum into a "thinking-skills" curriculum that trades "breadth for depth" by focusing on fewer topics while targeting the students' cognitive development. We employed existing research on the physics problem-solving expert-novice behavior, cognitive science and behavioral science findings, and educational psychology recommendations. Our pedagogy relies on didactic constructs such as the GW-ACCESS problem-solving protocol, learning progressions and concept maps that we have developed and implemented in our introductory physics course. These tools were designed based on TIPP. Their purpose is: (1) to help students build local and global coherent knowledge structures, (2) to develop more context-independent problem-solving abilities, (3) to gain confidence in problem solving, and (4) to establish connections between everyday phenomena and underlying physics concepts. We organize traditional and research-based physics problems such that students experience a gradual increase in complexity related to problem context, problem features and cognitive processes needed to solve the problem. The instructional environment that we designed allows for explicit monitoring, control and measurement of the cognitive processes exercised during the instruction period. It is easily adaptable to any kind of curriculum and can be readily adjusted throughout the semester. To assess the development of students' problem-solving abilities, we created rubrics that measure specific aspects of the thinking involved in physics problem solving. The Colorado Learning Attitudes about Science Survey (CLASS) was administered pre- and post-instruction to determine students' shift in dispositions towards learning physics. The Force Concept Inventory (FCI) was administered pre- and post-instruction to determine students' level of conceptual understanding. The results feature improvements in students' problem-solving abilities and in their attitudes towards learning physics.

NEXUS/Physics: An interdisciplinary repurposing of physics for biologists

2014-05-01

In response to increasing calls for the reform of the undergraduate science curriculum for life science majors and pre-medical students (Bio2010, Scientific Foundations for Future Physicians, Vision & Change), an interdisciplinary team has created NEXUS/Physics: a repurposing of an introductory physics curriculum for the life sciences. The curriculum interacts strongly and supportively with introductory biology and chemistry courses taken by life-science students, with the goal of helping students build general, multi-discipline scientific competencies. NEXUS/Physics stresses interdisciplinary examples and the content differs markedly from traditional introductory physics to facilitate this: it extends the discussion of energy to include interatomic potentials and chemical reactions, the discussion of thermodynamics to include enthalpy and Gibbs free energy and includes a serious discussion of random vs coherent motion including diffusion. The development of instructional materials is coordinated with careful education research. Both the new content and the results of the research are described in a series of papers for which this paper serves as an overview and context.

Promoting Collaborative Classrooms: The Impacts of Interdependent Cooperative Learning on Undergraduate Interactions and Achievement.

PubMed

Premo, Joshua; Cavagnetto, Andy; Davis, William B; Brickman, Peggy

2018-06-01

Collaboration is an important career skill and vital to student understanding of the social aspects of science, but less is known about relationships among collaborative-learning strategies, classroom climate, and student learning. We sought to increase the collaborative character of introductory undergraduate laboratory classrooms by analyzing a 9-week intervention in 10 classrooms ( n = 251) that participated in cooperative-learning modules (promoting interdependence via a modified jigsaw technique). Students in an additional 10 classrooms ( n = 232) completed the same material in an unstructured format representative of common educational practice. Results showed that, when between-class variance was controlled for, intervention students did not score higher on weekly quizzes, but science interest and prior science experience had a reduced relationship to quiz performance in intervention classrooms. Also, intervention classrooms showed increased collaborative engagement at both whole-class and individual levels (24 students at three time points), but the intervention was only one of several factors found to account for late-intervention classroom collaborative engagement (prosocial behavior and discussion practices). Taken together, findings suggest that integrating interdependence-based tasks may foster collaborative engagement at both small-group and whole-classroom levels, but by itself may not be enough to promote increased student achievement.
