Teaching genetics can be challenging because of the difficulty of the content and misconceptions students might hold. This thesis focused on using hands-on model activities, problem solving, and inquiry-based teaching/learning methods in order to increase student understanding in an introductory biology class in the area of genetics. Various activities using these three methods were implemented into the classes to address any misconceptions and increase student learning of the difficult concepts. The activities that were implemented were shown to be successful based on pre-post assessment score comparison. The students were assessed on the subjects of inheritance patterns, meiosis, and protein synthesis and demonstrated growth in all of the areas. It was found that hands-on models, problem solving, and inquiry-based activities were more successful in learning concepts in genetics and the students were more engaged than tradition styles of lecture.

The purpose of this quasi-experimental study was to measure the difference in science achievement between students who had been taught with an inquiry-based, hands-on pedagogical approach and those who had not. Improving student academic achievement and standardized test scores is the major objective of teachers, parents, school administrators, government entities, and students themselves. One major barrier to this academic success in Georgia, and the entire United States, has been the paucity of success in middle level science classes. Many studies have been conducted to determine the learning approaches that will best enable students to not only acquire a deeper understanding of science concepts, but to equip them to apply that new knowledge in their daily activities. Inquiry-based, hands-on learning involves students participating in activities that reflect methods of scientific investigation. The effective utilization of the inquiry-based learning approach demands inclusion of learners in a self-directed learning environment, the ability to think critically, and an understanding of how to reflect and reason scientifically. The treatment group using an inquiry-based, hands-on program did score slightly higher on the CRCT. However, the results revealed that there was not a significant difference in student achievement. This study showed that the traditionally instructed control group had slightly higher interest in science than the inquiry-based treatment group. The findings of this research study indicated that the NCLB mandates might need to be altered if there are no significant academic gains that result from the use of inquiry-based strategies.

One of the greatest impacts on the global carbon cycle is changes in land use. Making this concept relevant and inquiry-based for high school students is challenging. Many are familiar with reconstructing paleo-climate from ice core data, but few have a connection to current climate research. Many students ask questions like 'What will our area be like in 20 years?' or 'How much does planting trees help?' while few have the scientific language to engage in a discussion to answer these questions. Our work connects students to climate change research in several ways: first, teacher Keska Kemper engaged in field research with Dr. Heather Throop creating a 'teacher in the field' perspective for students in the classroom. Dr. Throop met with Keska Kemper's students several times to develop an inquiry-based field study. Students predicted and then measured rates of respiration between different soil types in an urban park close to their school. Students then could compare their results from Portland, Oregon to Throop's work across a rain gradient in Australia. Discussions about percent tree cover and soil carbon helped students see connections between land use changes and changes in carbon cycling. Last, students examined satellite imagery to determine percent tree cover and numberss of trees to compare to soil carbon in the same region. Students were able to examine imagery over the last 30 years to visualize land use changes in the greater Portland area.

A large number of American elementary school students are now studying science using the hands-on inquiry curricula developed in the 1990s: Insights; Full Option Science System (FOSS); and Science and Technology for Children (STC). A goal of these programs, echoed in the National Science Education Standards, is that children should gain abilities to do scientific inquiry and understanding about scientific inquiry. We have studied the degree to which students can do inquiries by using four hands-on performance assessments, which required one or three class periods. To be fair, the assessments avoided content that is studied in depth in the hands-on programs. For a sample of about 1000 fifth grade students, we compared the performance of students in hands-on curricula with an equal number of students with textbook curricula. The students were from 41 classrooms in nine school districts. The results show little or no curricular effect. There was a strong dependence on students' cognitive ability, as measured with a standard multiple-choice instrument. There was no significant difference between boys and girls. Also, there was no difference on a multiple-choice test, which used items released from the Trends in International Mathematics and Science Study (TIMSS). It is not completely clear whether the lack of difference on the performance assessments was a consequence of the assessments, the curricula, and/or the teaching.

Adapting a successful inquiry-based immersion program to create an Authentic, Hands-on, Field based Curriculum in Environmental Science at Barnard College T. C. Kenna, S. Pfirman, B. J. Mailloux, M. Stute, R. Kelsey, and P. Bower By adapting a successful inquiry-based immersion program (SEA semester) to the typical college format of classes, we are improving the technical and quantitative skills of undergraduate women and minorities in environmental science and improving their critical thinking and problem-solving by exposing our students to open-ended real-world environmental issues. Our approach uses the Hudson River Estuary as a natural laboratory. In a series of hands-on inquiry-based activities, students use advanced equipment to collect data and samples. Each class session introduces new analytical and data analysis techniques. All classes have the connecting theme of the river. Working with real data is open-ended. Our major findings as indicated by surveys as well as journaling throughout the semester are that the field- based experience significantly contributed to student learning and engagement. Journaling responses indicated that nearly all students discussed the importance and excitement of an authentic research experience. Some students were frustrated with data irregularities, uncertainty in methods and data, and the general challenge of a curriculum with inherent ambiguity. The majority were satisfied with the aims of the course to provide an integrative experience. All students demonstrated transfer of learned skills. This project has had a significant impact on our undergraduate female students: several students have pursued senior thesis projects stemming from grant activities, stating that the field activities were the highlight of their semester. Some students love the experience and want more. Others decide that they want to pursue a different career. All learn how science is conducted and have a better foundation to understand concepts such

A comparison of hands-on inquiry instruction with lecture instruction was presented to 134 Patterns and Process Biology students. Students participated in seven biology lessons that were selected from Biology Survey of Living Things (1992). A pre and post paper and pencil assessment was used as the data collecting instrument. The treatment group was taught using hands-on inquiry strategies while the non-treatment group was taught in the lecture method of instruction. The team teaching model was used as the mode of presentation to the treatment group and the non-treatment group. Achievement levels using specific criterion; novice (0% to 50%), developing proficiency (51% to 69%), accomplished (70% to 84) and exceptional or mastery level (85% to 100%) were used as a guideline to tabulate the results of the pre and post assessment. Rubric tabulation was done to interpret the testing results. The raw data was plotted using percentage change in test score totals versus reading level score by gender as well as percentage change in test score totals versus auditory vocabulary score by gender. Box Whisker plot comparative descriptive of individual pre and post test scores for the treatment and non-treatment group was performed. Analysis of covariance (ANCOVA) using MINITAB Statistical Software version 14.11 was run on data of the seven lessons, as well as on gender (male results individual and combined, and female results individual and combined) results. Normal Probability Plots for total scores as well as individual test scores were performed. The results suggest that hands-on inquiry based instruction when presented to special needs students including; at-risk; English as a second language limited, English proficiency and special education inclusive students' learning may enhance individual student achievement.

We held a series of astronomy workshops for local school teachers using astronomy activities from a course we give for Elementary Education majors. The school teachers provide us with feedback about successes and failures. Then we try the revised activities in the classroom. Via this in-service and pre-service feedback, the astronomy laboratory activities in the course have been completely revised over the last three years. The activities we use are almost entirely hands-on. The activities include use of log book (or journal) for describing outside-of-class observations of sunsets, phases of the moon, portable sundial, and the somewhat unique method we use to teach the constellations. In addition, all laboratory activity records are kept in the log book. Laboratory activities cover the use of fists to measure degrees, constellations, phases of the moon, relative distances and size of planets, Invent an Alien, lenses, images and telescopes, and the making of a comet. In our poster, based roughly on the theme of the seasons, we will describe a portable, multi-user sundial, length of the day display using newspaper data, two temperature/season activities, and a model demonstration of why the sundial shadows behave as they do.

The Lawrence Hall of Science (LHS) is University of California, Berkeley's public science center. Over the last decade, the Center for Technology Innovation at LHS has partnered with many institutions to establish a strong track record of developing successful technology solutions to support STEM teaching and learning within informal environments. Curation by subject-matter experts has been at the heart of many educational technology products from LHS and its partners that are directed at educators and families. This work includes: (1) popular digital libraries for inquiry-based activities at Howtosmile.org (NSF DRL #0735007) and NASA Earth and Space science education resources at NASAwavelength.org; and novel mobile apps like DIY Sun Science (NASA NNX10AE05G) and DIY Human Body (NIH 5R25OD010543) designed to scaffold exploration of STEM phenomena at home. Both NASA Wavelength and DIY Sun Science arose out of long-term collaborations with the Space Sciences Laboratory at UC Berkeley, Institute for Global Environmental Strategies (IGES), and other NASA-funded organizations, in partnership with NASA through cooperative agreements. This session will review the development, formative evaluation, and usage metrics for these two Earth and Space science-themed educational technology products directly relevant to the AGU community. Questions reviewed by presenters will include: What makes a good hands-on activity, and what essential information do educators depend on when searching for programming additions? What content and connections do families need to explore hands-on activities? How can technology help incorporate educational standards into the discovery process for learning experiences online? How do all these components drive the design and user experience of websites and apps that showcase STEM content?

During the summer of 2011, the Mālama Ke Ahupua`a (to care of our watershed) GEARUP summer program provided 25 under-served and under-represented minority public high school students (Hawaiian, part-Hawaiian, Filipino, Pacific Islanders) from Farrington High School (Kalihi, Honolulu) with a hands-on place-based multidiscipline course located within Manoa Valley (Ahupua`a O Kona) with the objective of engaging participants in scientific environmental investigations while exploring Hawaii's linkages between traditional knowledge, culture and science. The 4-week field program enabled students to collect samples along the perennial Manoa Stream and conduct water quality assessments throughout the Manoa watershed. Students collected science quality data from eight different sampling stations by means of field- and laboratory-based quantitative water quality testing equipment and GPS/GIS technology. While earning Hawaii DOE academic credits, students were able to document changes along the stream as related to pollution and urbanization. While conducting the various scientific investigations, students also participated in cultural fieldtrips and activities that highlighted the linkages between historical sustainable watershed uses by native Hawaiian communities, and their connections with natural earth processes. Additionally, students also participated in environmental service-learning projects that highlight the Hawaiian values of laulima (teamwork), mālama (to care for), and imi `ike (to seek knowledge). By contextualizing and merging hands-on place-based earth science inquiry with native Hawaiian traditional knowledge, students experienced the natural-cultural significance of their ahupua`a (watershed). This highlighted the advantages for promoting environmental literacy and geoscience education to under-served and under-represented minority populations in Hawaii from a rich native Hawaiian cultural framework.

The Hands-On Optics project began as a follow-up to the 2001 NSF planning grant "Optics Education -- A Blueprint for the 21st Century", which described the value of informal science programs in addressing the disconnect between the ubiquity of optics in everyday life and the noticeable absence of optics education in K-12 curricula and in informal science education programs. Key partners in the project are NOAO, SPIE-The International Society for Optical Engineering, and the Optical Society of America (OSA). The informal instructional materials created by the project are distributed through science centers nationwide and through the Mathematics, Engineering, Science Achievement Program (MESA) in a number of states, including Arizona, California, Washington, and Maryland. A key part of the project is the involvement, modeled after Project ASTRO, of optics professionals currently engaged in outreach activities and programs. Optics professionals (termed optics resource volunteers) are teamed with MESA and science center educators in implementing the program. These hands-on, high-interest, standards-connected activities and materials provide 6, three-hour-long optics activity modules that can be used in a variety of informal settings. We will describe the techniques used at NOAO to train educators, parents, and optics professionals who will work with the HOO activities as well as the different approaches needed for different informal education programs, ranging from Saturday programs, after-school programs, and science center programs. NOAO is developing the six modules and associated kits as well as competitions that have broad appeal to 12-year olds. Hands-On Optics: Making an Impact with Light (HOO) is a collaborative NSF-funded four-year informal science education program to excite students about science by actively engaging them in optics activities.

This study examines positive dispositions reported by middle school and high school students participating in programs that feature STEM-related activities. Middle school students participating in school-to-home hands-on energy monitoring activities are compared to middle school and high school students in a different project taking part in activities such as an after-school robotics program. Both groups are compared and contrasted with a third group of high school students admitted at the eleventh grade to an academy of mathematics and science. All students were assessed using the same science, technology, engineering and mathematics (STEM) dispositions instrument. Findings indicate that the after-school group whose participants self-selected STEM engagement activities, and the self-selected academy of mathematics and science group, each had highly positive STEM dispositions comparable to those of STEM professionals, while a subset of the middle school whole-classroom energy monitoring group that reported high interest in STEM as a career, also possessed highly positive STEM dispositions comparable to the STEM Professionals group. The authors conclude that several different kinds of hands-on STEM engagement activities are likely to foster or maintain positive STEM dispositions at the middle school and high school levels, and that these highly positive levels of dispositions can be viewed as a target toward which projects seeking to interest mainstream secondary students in STEM majors in college and STEM careers, can hope to aspire. Gender findings regarding STEM dispositions are also reported for these groups.
In brief: it is possible to have students do experiments in very large lecture classes. Evaluations show it works. Hands-on science, while traditional in many other disciplines, has not played a large role in astronomy teaching, though many of the concepts we deal with such as heat and pressure can be explored with simple experiments. 340 students in a large lecture class did an experiment with drink bottles, ice, warm water, and baggies to explore the dependence of pressure on temperature. They worked together in approximately 100 groups, working through a teaching sequence which included both a classic demonstration done by the instructor and a hands-on activity where they did the experiment themselves. This activity was carried out in a rather challenging setting: a large lecture room with fixed seats and no plumbing. Handling and disposing of the materials was only modestly more challenging than teaching a regular class. Student evaluations and student performance on exam questions demonstrated that the activity was successful. This research was part of DISCUS (Delaware Innovative Science/Math Collaborative for Undergraduate Success), an initiative supported by the Delaware Department of Public Instruction and the National Science Foundation (DUE-9553787).

Inquiry science, as called for by reform-minded organizations such as the National Research Council (1996), offers a platform with the potential for introducing all students to the practice of science while maintaining focus on key concepts and theories. This project followed two small groups as they completed an inquiry unit on genetics at a Midwestern high school. I investigated whether levels of student-to-teacher, student-to-student, student-apparatus, and student-concept connections were approximately equal across all students in each of the two groups. I found differences among students in levels of student-to-teacher, student-to-student, and student-concept connections. From a situated idiopathic perspective, these differences may indicate different levels of opportunity-to-learn. At a more abstract (nomothetic) level, these differences may be due to emergent divisions of labor (roles) within the two groups. From the perspective of Activity Theory (Leont'ev, 1978; Engestrom, 1987), roles serve as important mediators that simultaneously allow the social unit to accomplish its objectives, while shaping the development of participants. I describe three roles that capture modes of participation for students interacting in the small groups, and that may contribute to what Engestrom (2001) calls subject-producing activity systems: networked contributor, social member, and isolate. This paper also describes tools for teachers and researchers to use in identifying levels of mediation and roles as they occur in small groups.

The call for inquiry science to be a part of the school science curriculum is popular in many parts of the world. While some research in this area revealed success stories of students' learning when they are engaged in student-directed, open-ended scientific inquiry activities, others are more sceptical about how these activities impact students' learning in and of science. Using the microanalysis of classroom talk in a grade-six science classroom dealing with the conversion of energy, we illustrate the dilemma in communicative approach used by a teacher when using an inductive hands-on activity to teach canonical science content. We unravel the complexity between dialogic-authoritative approaches in establishing learning as well as the need to fulfil the teaching purposes set for each lesson. Here we illustrate how the use of fine grain analysis of classroom talk and interaction can reveal the details of classroom learning, such as mismatch of teaching purposes and adopting appropriate approach to fulfil the intended teaching purpose.

We describe a new inquiry design aimed at teaching advanced high-school to senior college students the basics of stellar populations. The inquiry is designed to have students come up with their own version of the Hertzsprung-Russell diagram as a tool to understand how stars evolve based on their color, mass, and luminosity. The inquiry makes use of pictures and spectra of stars, which the students analyze and interpret to answer the questions they come up with at the beginning. The students undergo a similar experience to real astronomers, using the same tools and methods to figure out the phenomena they are trying to understand. Specifically, they use images and spectra of stars, and organize the data via tables and plots to find trends that will then enable them to answer their questions. The inquiry also includes a "thinking tool" to help connect the trends students observe to the larger picture of stellar evolution. We include a description of the goals of the inquiry, the activity description, the motivations and thoughts that went into the design of the inquiry, and reflections on how the inquiry activity worked in practice.

We are developing various systematic hands on devices for progress of active learning (AL) to improve students' conceptual understanding in physics laws. We are promoting AL methods in physics education for getting deeper conceptual understanding by using various ICT-based hands on devices and using visualizing ICT tools with milliseconds resolution. Here we investigate AL modules on collisions of big balloon pendulum with another known mass pendulum to get directly the air mass in the big balloon. We also discuss on Newton's laws of blowgun darts systems by using tapioca straws where we get definite works and energy just proportional to the length of the pipes of connected tapioca straws. These AL plans by using modules of big balloon system and blowgun-darts system are shown to be very effective for deeper conceptual understanding of Newton's Laws in almost frictionless worlds.

The "Healthy Heart Race" activity provides a hands-on demonstration of cardiovascular function suitable for lay audiences. It was field tested during the United States of America Science and Engineering Festival held in Washington, DC, in October 2010. The basic equipment for the activity consisted of lengths of plastic tubing, a hand pump, collection containers, clamps, and simulated blood prepared by tinting water with red food coloring. Student participants were first asked to experience the effort required to pump through an unaltered tube. A presenter then applied a strong clamp that pinched each tube downstream from the pump, and students were asked to pump against the increased resistance. The students' observations were then used as the basis for discussions of atherosclerosis and coronary heart disease with the presenters. Distribution of informative postcards during the 2 days of the festival indicated that at least 2,500 students completed the Healthy Heart Race activity. Our experiences to date suggest that the Healthy Heart Race activity can be accomplished effectively in the high-volume, high-distraction environment of a science fair or museum.

Motivating students is one of the most challenging things we do as educators. We know that students need to be engaged to fully appreciate and learn what has been taught; the secret consists in nurturing student engagement. One of the newer ways to involve students and foster motivation in their Science learning consists in focusing on their usage and on applying knowledge and skills in their real-life. Students usually are engaged in authentic teaching pathway. Learning focusing on the experience helps teachers to improve classroom management by gathering students around a common organized activity. Hands-on activities support problem-based approaches to learning by focusing on the experience and process of investigating, proposing and creating solutions developing critical thinking skills and enlarge student's scientific glossary. We utilized in our classroom some lab activities that we learned at an ESA/GTTP Teacher training Workshop 2014 program at the Lorentz Center Leiden, Netherlands. "Cooking a comet - Ingredients for life" "Demonstration of the second Kepler's law using marbles" New media equipment, as student's own smartphones, can increase the teaching impact speaking the same language used by the students every day. They can measure magnetic fields, their GPS coordinates (longitude and latitude), and so on. In this way we can measure distances as parallax using mobile devices and simulating distance measurements in the classroom, on the school campus. The smartphone is the device with which the students answer questions, take decisions, and solve quests. Students infact can observe the Universe from their classroom and scientifically they can watch the Sun with "Google sky map" or "Star walk" are excellent tools to learn your way around the night sky .As teachers we used these apps in the classroom when Sun goes through the constellations so our students don't believe in horoscopes. This paper is focused on hands on activities and the effects of the

What color is the sky today? The GLOBE Kids - Anita, Simon, and Dennis want to know why the sky isn't always the same shade of blue and sometimes isn't even blue. Through the new Elementary GLOBE Aerosols Storybook and Learning Activities, the GLOBE Kids learn that there's a lot more than air in the atmosphere, which can affect the colors we see in the sky. There are four hands-on activities in this unit: 1) Sky Observers - Students make observations of the sky, record their findings and share their observation reports with their peers. The activity promotes active observation and recording skills to help students observe sky color, and recognize that sky color changes; 2) Why (Not) So Blue? - Students make predictions about how drops of milk will affect color and visibility in cups of water representing the atmosphere to help them understand that aerosols in the atmosphere have an effect on sky conditions, including sky color and visibility. The activity also introduces the classification categories for daytime sky color and visibility; 3) See the Light - Students use prisms and glue sticks to explore the properties of light. The activity demonstrates that white light is made up of seven colors that represent different wavelengths, and illustrates why the sky is blue during the day and red at sunset; 4) Up in the Air - Students work in groups to make an aerosol sampler, a simple adhesive tool that allows students to collect data and estimate the extent of aerosols present at their school, understanding that, in fact, there are particles in the air we breathe.

Background In order to eliminate the fear-factor associated with learning FluidMechanics, a new instructional method was created. The new method is neatly packaged into hands-on activities (as defined in this dissertation) in order to ease implementation and dissemination into an engineering class. Because of variations in learning and teaching styles of students and lecturers , the hands-on activities are designed to help the lecturer communicate key concepts to a wider spectrum of students. Typically engineering lectures are biased towards intuitive, verbal, reflective and sequential learners whereas few engineering students fall into these categories.  The hands-on activities are meant to bridge the communication gap resulting in a positive educational experience. Purpose In order to assess the impact of the new instructional method, a new engineering education experimental design was created. Engineering Education research is very interdisciplinary in nature and therefore requires cooperation from multiple Colleges including, but not limited to, Engineering, Education, and Science (Statistics). Design/Method Two groups of engineering students were allocated to test the hypothesis, "Does being exposed to hands-on activities (a new instructional method) in a section of MAE 308 - Fluid Mechanics result in higher student achievement?" Comparison of the quiz results between the control group and experimental group assessed the effectiveness of the hands-on activities. The problems within each quiz correlated to a level of Bloom's Taxonomy. A comparison of the results on the problems assessed which level of Bloom's were impacted. NHST was performed to determine statistical significance while the effect size was calculated to determine practical significance. Results The hands-on activities have a positive effect on learning. 3.30% more students per class perform better on each problem on each quiz. The hands-on activity, Rainbow Layer Cake, was a superstar

GeoBus (www.geobus.org.uk) is an educational outreach project that was developed in 2012 by the Department of Earth and Environmental Sciences at the University of St Andrews, and it is sponsored jointly by industry and the UK Research Councils (NERC and EPSRC). The aims of GeoBus are to support the teaching of Earth Science in secondary schools by providing teaching resources that are not readily available to educators, to inspire young learners by incorporating new science research outcomes in teaching activities, and to provide a bridge between industry, higher education institutions, research councils and schools. Since its launch, GeoBus has visited over 160 different schools across the length and breadth of Scotland. Just under 35,000 pupils have been involved in practical hands-on Earth science learning activities since the project began in 2012, including many in remote and disadvantaged regions. The resources that GeoBus brings to schools include all the materials and equipment needed to run 50 - 80 minute workshops, and half- or whole-day Enterprise Challenges and field excursions. Workshops are aimed at a class of up to 30 pupils and topics include minerals, rocks, fossils, geological time, natural resources, climate change, volcanoes, earthquakes, and geological mapping. As with all GeoBus activities, the inclusion of equipment and technology otherwise unavailable to schools substantially increases the engagement of pupils in workshops. Field excursions are increasingly popular, as many teachers have little or no field trainng and feel unable to lead this type of activity. The excursions comprise half or full day sessions for up to 30 pupils and are tailored to cover the local geology or geomorphology. Enterprise Challenge are half or full day sessions for up to 100 pupils. Topics include "Journey to Mars", "Scotland's Rocks", "Drilling for Oil", and "Renewable Energy". Both of the energy Enterprise Challenges were designed to incorporates ideas and

Few research studies have been conducted related to inquiry-based scientific teaching methodologies and NCLB-required state testing. The purpose of this study was to examine the relationship between the strategies used by seventh-grade science teachers in Illinois and student scores on the Illinois Standards Achievement Test (ISAT) to aid in determining best practices/strategies for teaching middle school science. The literature review defines scientific inquiry by placing teaching strategies on a continuum of scientific inquiry methodologies from No Inquiry (Direct Instruction) through Authentic Inquiry. Five major divisions of scientific inquiry: structured inquiry, guided inquiry, learning cycle inquiry, open inquiry, and authentic inquiry, have been identified and described. These five divisions contain eight sub-categories: demonstrations; simple or hands-on activities; discovery learning; variations of learning cycles; problem-based, event-based, and project-based; and student inquiry, science partnerships, and Schwab's enquiry. Quantitative data were collected from pre- and posttests and surveys given to the participants: five seventh grade science teachers in four Academic Excellence Award and Spotlight Award schools and their 531 students. Findings revealed that teachers reported higher inquiry scores for themselves than for their students; the two greatest reported factors limiting teachers' use of inquiry were not enough time and concern about discipline and large class size. Although the correlation between total inquiry and mean difference of pre- and posttest scores was not statistically significant, the survey instrument indicated how often teachers used inquiry in their classes, not the type of inquiry used. Implications arose from the findings that increase the methodology debate between direction instruction and inquiry-based teaching strategies; teachers are very knowledgeable about the Illinois state standards, and various inquiry-based methods

Activities by NASA scientists and teachers focus on integrating Planetary Science activities with existing Earth science, math, and language arts curriculum. The wealth of activities that highlight missions and research pertaining to the exploring the solar system allows educators to choose activities that fit a particular concept or theme within their curriculum. Most of the activities use simple, inexpensive techniques that help students understand the how and why of what scientists are learning about comets, asteroids, meteorites, moons and planets. With these NASA developed activities students experience recent mission information about our solar system such as Mars geology and the search for life using Mars meteorites and robotic data. The Johnson Space Center ARES Education team has compiled a variety of NASA solar system activities to produce an annotated thematic outline useful to classroom educators and informal educators as they teach space science. An important aspect of the outline annotation is that it highlights appropriate science content information and key science and math concepts so educators can easily identify activities that will enhance curriculum development. The outline contains URLs for the activities and NASA educator guides as well as links to NASA mission science and technology. In the informal setting educators can use solar system exploration activities to reinforce learning in association with thematic displays, planetarium programs, youth group gatherings, or community events. Within formal education at the primary level some of the activities are appropriately designed to excite interest and arouse curiosity. Middle school educators will find activities that enhance thematic science and encourage students to think about the scientific process of investigation. Some of the activities offered are appropriate for the upper levels of high school and early college in that they require students to use and analyze data.

Introduction: Activities developed by NASA scientists and teachers focus on integrating Planetary Science activities with existing Earth science, math, and language arts curriculum. Educators may choose activities that fit a particular concept or theme within their curriculum from activities that highlight missions and research pertaining to exploring the solar system. Most of the activities use simple, inexpensive techniques that help students understand the how and why of what scientists are learning about comets, asteroids, meteorites, moons and planets. The web sites for the activities contain current information so students experience recent mission information such as data from Mars rovers or the status of Stardust sample return. The Johnson Space Center Astromaterials Research and Exploration Science education team has compiled a variety of NASA solar system activities to produce an annotated thematic syllabus useful to classroom educators and informal educators as they teach space science. An important aspect of the syllabus is that it highlights appropriate science content information and key science and math concepts so educators can easily identify activities that will enhance curriculum development. The outline contains URLs for the activities and NASA educator guides as well as links to NASA mission science and technology. In the informal setting, educators can use solar system exploration activities to reinforce learning in association with thematic displays, planetarium programs, youth group gatherings, or community events. In both the informal and the primary education levels the activities are appropriately designed to excite interest, arouse curiosity and easily take the participants from pre-awareness to the awareness stage. Middle school educators will find activities that enhance thematic science and encourage students to think about the scientific process of investigation. Some of the activities offered may easily be adapted for the upper

Active engagement has become the focus of many early childhood science education curricula and standards. However, active engagement usually emphasizes getting children engaged with science solely through hands-on activities. Active engagement by way of hands, heads, and hearts are kept separate and rarely discussed in terms of getting all to work together, although inquiry-based education and student interest have been accepted as important in science education. The current study is an inquiry-based research. It aims to describe and examine projects and activity stations for preschoolers in a Turkish preschool classroom bringing together the pieces of the puzzle of science education, called here 'Hands-Heads-Hearts-on Science Education'. The study, conducted from a qualitative-interpretivist paradigm, reveals that activity stations and projects create a context for hands-on (active engagement), heads-on (inquiry based or mental-engagement), and hearts-on (interest based) science education. It is found that activity stations and projects, when maintained by appropriate teacher-support, create a playful context in which children can be actively and happily engaged in science-related inquiry.

There is a major movement in science education towards the inclusion of science inquiry and process. Guided-inquiry instruction is expected to have a positive impact on students' concrete and conceptual knowledge along with their ability to engage in the practices of science. This study examined the impact of inquiry-based teaching on student achievement. The topics of reactions and stoichiometry were taught in two different periods of first-year secondary honors chemistry. Both classes received the same lectures and assignments for this curriculum and both classes performed the same laboratory activities. However, one class received traditional, step-by-step (often called "cookbook") laboratory instructions while the other class developed their own procedures and made decisions about data to complete the laboratory activities. Pre- and post-tests were given to each class, followed by a test of retention after ten weeks. The results of this study indicate that inquiry-based instruction has a positive impact on student achievement. A significant increase between pre- and post- test scores for the experimental group as opposed to the scores for the control group suggests that achievement was correlated with guided inquiry instruction methods. Additionally, a notable trend suggested that guided inquiry instruction has a positive effect on learning retention.

This thesis presents a qualitative investigation of the effects of social competence on the participation of students with learning disabilities (LD) in the science learning processes associated with collaborative, guided inquiry learning. An inclusive Grade 2 classroom provided the setting for the study. Detailed classroom observations were the primary source of data. In addition, the researcher conducted two interviews with the teacher, and collected samples of students' written work. The purpose of the research was to investigate: (a) How do teachers and peers mediate the participation of students with LD in collaborative, guided inquiry science activities, (b) What learning processes do students with LD participate in during collaborative, guided inquiry science activities, and (c) What components of social competence support and constrain the participation of students with LD during collaborative, guided inquiry science activities? The findings of the study suggest five key ideas for research and teaching in collaborative, guided inquiry science in inclusive classrooms. First, using a variety of collaborative learning formats (whole-class, small-group, and pairs) creates more opportunities for the successful participation of diverse students with LD. Second, creating an inclusive community where students feel accepted and valued may enhance the academic and social success of students with LD. Third, careful selection of partners for students with LD is important for a positive learning experience. Students with LD should be partnered with academically successful, socially competent peers; also, this study suggested that students with LD experience more success working collaboratively in pairs rather than in small groups. Fourth, a variety of strategies are needed to promote active participation and positive social interactions for students with and without LD during collaborative, guided inquiry learning. Fifth, adopting a general approach to teaching

Preservice elementary teachers need to begin developing their pedagogical design capacities for inquiry by learning how to translate their conceptions of inquiry into classroom practice through the adaptation and enactment of curriculum materials. Using both qualitative and quantitative research methods, I draw upon cultural-historical activity theory (CHAT) to investigate preservice elementary teachers' curriculum design and development of pedagogical design capacity for inquiry during the final year of their teacher education program. This study involved analysis of curricular artifacts and survey data from 46 prospective elementary teachers in two sections of an undergraduate elementary science teaching methods course, as well as interviews, observational fieldnotes, reflective journals, and other artifacts from four preservice teachers from this larger group studied during the methods and student teaching semesters. Results show that preservice teachers were able to translate their espoused inquiry frameworks into planned and enacted science lessons. This involved adapting existing curriculum materials to better promote specific inquiry practices, but also to fundamentally shift the nature of classroom science. The preservice teachers' curriculum design efforts were constrained, however, by features of their institutional contexts and subject to emergent tensions. In attempting to resolve these tensions through curriculum design for inquiry, the preservice teachers ultimately articulated a fundamental contradiction between two distinct and competing visions for classroom inquiry: traditional classroom science, which promotes students' reproduction of scientific explanations by objectifying students, and a novel form of classroom inquiry that repositions students as contributing community members involved in the co-construction of knowledge through lesson-specific shared problem-spaces. For each of the preservice teachers, this contradiction had important

It is evident that "experientially-based" instruction and "active student engagement" are advantageous for effective science learning. However, "hands-on" and "minds-on" aspects can occur in both inquiry and direct science instruction, and convincing comparative evidence for the superiority of either mode remains rare. Thus, the pertinent question…

This study investigated the impact of three commonly used cardiovascular model-assisted activities on student learning and student attitudes and perspectives about science. College students enrolled in a Human Anatomy and Physiology course were randomly assigned to one of three experimental groups (organ dissections, virtual dissections, or plastic models). Each group received a 15-min lecture followed by a 45-min activity with one of the treatments. Immediately after the lesson and then 2 mo later, students were tested on anatomy and physiology knowledge and completed an attitude survey. Students who used plastic models achieved significantly higher overall scores on both the initial and followup exams than students who performed organ or virtual dissections. On the initial exam, students in the plastic model and organ dissection treatments scored higher on anatomy questions than students who performed virtual dissections. Students in the plastic model group scored higher than students who performed organ dissections on physiology questions. On the followup exam, when asked anatomy questions, students in the plastic model group scored higher than dissection students and virtual dissection students. On attitude surveys, organ dissections had higher perceived value and were requested for inclusion in curricula twice as often as any other activity. Students who performed organ dissections were more likely than the other treatment groups to agree with the statement that "science is fun," suggesting that organ dissections may promote positive attitudes toward science. The findings of this study provide evidence for the importance of multiple types of hands-on activities in anatomy laboratory courses.

In the course of inquiry activities similar to those of real scientists, learners are supposed to develop knowledge both on the level of observable phenomena and on the level of explanatory theories. However, some theories involve theoretical entities (e.g., "Weiss domains") that cannot be observed directly and therefore may be hard to…

The project is collaboration between two scientific societies, the Optical Society of America (OSA) and SPIE - The International Society for Optical Engineering and the National Optical Astronomy Observatory (NOAO). The program is designed to bring science education enrichment to thousands of underrepresented middle school students in more than ten states, including female and minority students, who typically have not been the beneficiaries of science and engineering resources and investments. HOO provides each teacher with up to six activity modules, each containing enough materials for up to 30 students to participate in 6-8 hours of hands-on optics-related activities. Sample activities, developed by education specialists at NOAO, include building kaleidoscopes and telescopes, communicating with a beam of light, and a hit-the-target laser beam challenge. Teachers engage in two days of training and, where possible, are partnered with a local optics professional (drawn from the local rosters of SPIE and OSA members) who volunteers to spend time with the teacher and students as they explore the module activities. Through these activities, students gain experience and understanding of optics principles, as well as learning the basics of inquiry, critical thinking, and problem solving skills involving optics, and how optics interfaces with other disciplines. While the modules were designed for use in informal after- school or weekend sessions, the number of venues has expanded to large and small science centers, Boys and Girls Clubs, Girl Scouts, summer camps, family workshops, and use in the classroom.

Inquiry-based learning is considered a useful technique to strengthen the critical thinking skills of students. The National Science Standards emphasize its use and the complexities and challenge it provides are well suited for meeting the needs of the gifted. While many studies have documented the effectiveness of this type of instruction, there is a lack of research on growth in higher-order thinking through participation in science inquiry. This study investigated such growth among a small group of gifted fifth-grade students. In this study a group of fifth-grade gifted science students completed a series of three forensics inquiry lessons, and documented questions, ideas and reflections as they constructed evidence to solve a crime. From this class of students, one small group was purposely selected to serve as the focus of the study. Using qualitative techniques, the questions and statements students made as they interacted in the activity were analyzed. Videotaped comments and student logs were coded for emerging patterns and also examined for evidence of increased levels of higher-order thinking based on a rubric that was designed using the six levels of Bloom's Taxonomy. Evidence from this study showed marked increase in and deeper levels of higher-order thinking for two of the students. The other boy and girl showed progress using the inquiry activities, but it was not as evident. The social dynamics of the group seemed to hinder one girl's participation during some of the activities. The social interactions played a role in strengthening the exchange of ideas and thinking skills for the others. The teacher had a tremendous influence over the production of higher-level statements by modeling that level of thinking as she questioned the students. Through her practice of answering a question with a question, she gradually solicited more analytical thinking from her students.

This study of online science teachers' opinions addressed the use of virtual labs in online courses. A growing number of schools use virtual labs that must meet mandated laboratory standards to ensure they provide learning experiences comparable to hands-on labs, which are an integral part of science curricula. The purpose of this qualitative case study was to examine teachers' perceptions of the quality and effectiveness of high school virtual labs. The theoretical foundation was constructivism, as labs provide student-centered activities for problem solving, inquiry, and exploration of phenomena. The research questions focused on experienced teachers' perceptions of the quality of virtual vs. hands-on labs. Data were collected through survey questions derived from the lab objectives of The Next Generation Science Standards . Eighteen teachers rated the degree of importance of each objective and also rated how they felt virtual labs met these objectives; these ratings were reported using descriptive statistics. Responses to open-ended questions were few and served to illustrate the numerical results. Many teachers stated that virtual labs are valuable supplements but could not completely replace hands-on experiences. Studies on the quality and effectiveness of high school virtual labs are limited despite widespread use. Comprehensive studies will ensure that online students have equal access to quality labs. School districts need to define lab requirements, and colleges need to specify the lab experience they require. This study has potential to inspire positive social change by assisting science educators, including those in the local school district, in evaluating and selecting courseware designed to promote higher order thinking skills, real-world problem solving, and development of strong inquiry skills, thereby improving science instruction for all high school students.

In the Environmental Literacy and Inquiry middle school Climate Change curriculum we focus on essential climate literacy principles with an emphasis on weather and climate, Earth system energy balance, greenhouse gases, paleoclimatology, and how human activities influence climate change (http://www.ei.lehigh.edu/eli/cc/). It incorporates a related set of a framework and design principles to provide guidance for the development of the geospatial technology-integrated Earth and environmental science curriculum materials. Students use virtual globes, Web-based tools including an interactive carbon calculator and geologic timeline, and inquiry-based lab activities to investigate climate change topics. The curriculum includes educative curriculum materials that are designed to promote and support teachers' learning of important climate change content and issues, geospatial pedagogical content knowledge, and geographic spatial thinking. The curriculum includes baseline instructional guidance for teachers and provides implementation and adaptation guidance for teaching with diverse learners including low-level readers, English language learners and students with disabilities. In the curriculum, students use geospatial technology tools including Google Earth with embedded spatial data to investigate global temperature changes, areas affected by climate change, evidence of climate change, and the effects of sea level rise on the existing landscape. We conducted a designed-based research implementation study with urban middle school students. Findings showed that the use of the Climate Change curriculum showed significant improvement in urban middle school students' understanding of climate change concepts.

Most high school and introductory college physics classes study simple harmonic motion and various wave phenomena. With the majority of states adopting the Next Generation Science Standards1 and pushing students to explore the scientific process for themselves, there is a growing demand for hands-on inquiry activities that involve and develop more data analysis and computational thinking skills. This article outlines several options for using an engaging standing wave phenomenon, Faraday waves, in physics classes. These options include the instructor using Faraday waves as a class demonstration of interesting fluid and wave properties, students doing an inquiry lab to investigate several properties of Faraday waves on water droplets, and the possibility of smaller numbers of students using Faraday waves as an independent research topic.

A semester-long, standards-based, hands-on physics curriculum appropriate for the fifth grade was developed. Previously available curricula were successful in using hands-on activities to teach basic fifth-grade physics skills and concepts, but did not attempt to foster understanding of the fundamental underlying physics. We expanded the role of inquiry-based instruction to expose students to the fundamental physics behind electricity, forces, energy, light and sound. Central to the course, the Bohr model of the atom was used as a key tool both to motivate exploration of these topics as well as to develop basic conceptual understanding of fundamental ideas in quantum and electromagnetic physics. The curriculum was designed to be compatible with both district and state-mandated standards in a high-stakes test environment. This work was supported by NSF grant DGE-0231909.

Hands-on Universe is a project born at UC@Berkeley. A project devoted to enrich the teaching of Astronomy within the classroom environment with a different approach, more connected to the new technologies. Its main goals are not only to promote the use of such technologies but also to reawaken on students the taste for STEM (Science, technologies, engineering and math) related issues and also to increase their scientific culture. Eight countries in Europe decided to adopt the method and, funded by MINERVA, formed the European Hands-on Universe. Several resources were produced and a data reduction software developed http://www.euhou.net/.Other European countries are interested and should join this coordinated effort in the near future. At an international level there are 20 countries using this approach. There are plans to develop scientific cooperation among these countries. Pilot scientific research projects in schools are being tested in EU-HOU schools, Russia and USA. There is also a game being developed to be used as a new tool for teaching scientific content in the classroom environment. An effort to develop an international network of scientific / educational collaboration is the next step.

Recent research reveals that students' interest in school science begins to decline at an early age. As this lack of interest could result in fewer individuals qualified for scientific careers and a population unprepared to engage with scientific societal issues, it is imperative to investigate ways in which interest in school science can be increased. Studies have suggested that inquiry learning is one way to increase interest in science. Inquiry learning forms the core of the primary syllabus in Singapore; as such, we examine how inquiry practices may shape students' perceptions of science and school science. This study investigates how classroom inquiry activities relate to students' interest in school science. Data were collected from 425 grade 4 students who responded to a questionnaire and 27 students who participated in follow-up focus group interviews conducted in 14 classrooms in Singapore. Results indicate that students have a high interest in science class. Additionally, self-efficacy and leisure-time science activities, but not gender, were significantly associated with an increased interest in school science. Interestingly, while hands-on activities are viewed as fun and interesting, connecting learning to real-life and discussing ideas with their peers had a greater relation to student interest in school science. These findings suggest that inquiry learning can increase Singaporean students' interest in school science; however, simply engaging students in hands-on activities is insufficient. Instead, student interest may be increased by ensuring that classroom activities emphasize the everyday applications of science and allow for peer discussion.

The action of the enzyme catalase on aqueous hydrogen peroxide to generate oxygen gas is a well-established demonstration (1-3). Catalase is typically obtained by aqueous extraction of a potato, and the potato extract is mixed together with 3% hydrogen peroxide. The oxygen that is produced can be collected over water. Variations on the procedure can demonstrate the dependence of catalytic activity on temperature or the presence of inhibitors (1, 2). The University of Colorado at Denver has used a version of this procedure as a laboratory in its second-semester course for nonmajors. Recently, students have been allowed to expand upon the procedures prescribed in the laboratory handout in an open-ended project format. We explored some of these variations in detail, and the results provided here offer ideas, centered around this laboratory, for open-ended projects that can be used in an inquiry-based approach.

Research in science education suggests that teachers' beliefs are linked to the use of inquiry-based instruction; teachers holding a constructivist belief are more likely to engage in student-centered activities in the classroom. However, there is currently little research on the ways in which teachers' beliefs change over time, and in particular, the relationship between instructional activities in teacher education programs and their impact on teachers' beliefs. We examined shifts in secondary preservice teachers' belief orientations as they progressed through a science methods course. We found that overall many of the preservice teachers progressed in their orientation beliefs from a teacher-centered orientation to more student-centered orientation. We characterized four trajectories of change or clusters that describe how preservice teachers' beliefs changed over the course of the semester (15 weeks). We also describe the different ways in which preservice teachers reacted to specific instructional activities, and how those activities influenced their belief orientation. In particular, we found that preservice teachers in a cluster that exhibited a particular trajectory (progression or regression toward/away from student-centered belief orientation) reacted differently to some activities compared to preservice teachers in some other clusters. We discuss these shifts as reflecting changes in priorities of beliefs within belief systems. We argue that teacher educators need to think carefully about the interplay of these beliefs when designing activities so that they can respond (i.e., to a reversal in beliefs) during the course rather than waiting until the end.

Initiated by Frank Oppenheimer in 1969, the Exploratorium in San Francisco has been the model for hands-on science museums throughout the world. The key idea has been to bring people with all levels of scientific background in contact with interesting and attractive exhibits that require the active participation of the visitor. Unfortunately, many science museums are now forced to cater primarily to very young audiences, often 8 years old or less, with predictable constraints on the intellectual depth of their exhibits. To counter this trend, the author has constructed several hands-on displays for the University of Michigan Physics Department that demonstrate: (1) magnetic levitation of pyrolytic graphite, (2) the varied magnetic induction effects in aluminum, copper and air, (3) chaotic motion of a double pendulum, (4) conservation of energy and momentum in a steel ball magnetic accelerator, (5) the diffraction pattern of red and green laser pointer beams created by CDs and DVDs, (6) a magnetic analog of the refraction of light at a dielectric boundary and (7) optical rotation of light in an aqueous fructose solution. Each of these exhibits can be constructed for something like $1000 or less and are robust enough to withstand unsupervised public use. The dynamic behavior of these exhibits will be shown in accompanying video sequences. The following story has a history that goes back quite a few years. In the late 70's, I was spending time at the Stanford Linear Accelerator Center accompanied by my family that included our two grade school children. Needless to say, we much enjoyed weekend excursions to all sorts of interesting sites in the Bay Area, especially the Exploratorium, an unusual science museum created by Frank Oppenheimer that opened in 1969. The notion that exhibits would be designed specifically for "hands-on" interactions was at that time quite revolutionary. This idea captivated a number of people everywhere including a friend in Ann Arbor, Cynthia

The vision science activity was originally designed for the 2007 Center for Adaptive Optics (CfAO) Summer School. Participants were graduate students, postdoctoral researchers, and professionals studying the basics of adaptive optics. The majority were working in fields outside vision science, mainly astronomy and engineering. The primary goal of the activity was to give participants first-hand experience with the use of a wavefront sensor designed for clinical measurement of the aberrations of the human eye and to demonstrate how the resulting wavefront data generated from these measurements can be used to assess optical quality. A secondary goal was to examine the role wavefront measurements play in the investigation of vision-related scientific questions. In 2008, the activity was expanded to include a new section emphasizing defocus and astigmatism and vision testing/correction in a broad sense. As many of the participants were future post-secondary educators, a final goal of the activity was to highlight the inquiry-based approach as a distinct and effective alternative to traditional laboratory exercises. Participants worked in groups throughout the activity and formative assessment by a facilitator (instructor) was used to ensure that participants made progress toward the content goals. At the close of the activity, participants gave short presentations about their work to the whole group, the major points of which were referenced in a facilitator-led synthesis lecture. We discuss highlights and limitations of the vision science activity in its current format (2008 and 2009 summer schools) and make recommendations for its improvement and adaptation to different audiences.

Emphasis on improving higher level biology education continues. A new two-step approach to the experimental phases within an outreach gene technology lab, derived from cognitive load theory, is presented. We compared our approach using a quasi-experimental design with the conventional one-step mode. The difference consisted of additional focused discussions combined with students writing down their ideas (step one) prior to starting any experimental procedure (step two). We monitored students' activities during the experimental phases by continuously videotaping 20 work groups within each approach ( N = 131). Subsequent classification of students' activities yielded 10 categories (with well-fitting intra- and inter-observer scores with respect to reliability). Based on the students' individual time budgets, we evaluated students' roles during experimentation from their prevalent activities (by independently using two cluster analysis methods). Independently of the approach, two common clusters emerged, which we labeled as `all-rounders' and as `passive students', and two clusters specific to each approach: `observers' as well as `high-experimenters' were identified only within the one-step approach whereas under the two-step conditions `managers' and `scribes' were identified. Potential changes in group-leadership style during experimentation are discussed, and conclusions for optimizing science teaching are drawn.

The purpose of this study was to find how the teacher could help students formulate scientific hypotheses. Data came from two microteaching episodes in which two groups of pre-service secondary science teachers taught high school students as they were engaged in abductive inquiry activities of earth science. Multiple data sources including video recordings of the microteaching, the pre-service teachers' oral and written reports, student worksheets, and instructional materials were examined. The analysis identified four categories of teaching strategies which could be used by science teachers to help students in hypothesis-generating inquiry. These included: (1) expanding and activating students' background knowledge, (2) providing analogies, (3) questioning, and (4) encouraging students to use alternative forms of representation. Implications for science education as well as for further research are suggested.

Inquiry-based activities that utilize the Cool Cosmos image galleries have been designed and developed by K12 teachers enrolled in The Invisible Universe Online for Teachers course. The exploration activities integrate the Our Infrared World Gallery (http://coolcosmos.ipac.caltech.edu/image_galleries/our_ir_world_gallery.html) with either the Infrared Zoo gallery (http://coolcosmos.ipac.caltech.edu/image_galleries/ir_zoo/index.html) or the Infrared Yellowstone image http://coolcosmos.ipac.caltech.edu/image_galleries/ir_yellowstone/index.html) and video (http://coolcosmos.ipac.caltech.edu/videos/ir_yellowstone/index.html) galleries. Complete instructor guides have been developed for the activities and will be presented by the authors in poster and CD form. Although the activities are written for middle and highschool learners, they can easily be adapted for college audiences. The Our Infrared World Gallery exploration helps learners think critically about visible light and infrared light as they compare sets of images (IR and visible light) of known objects. For example: by taking a regular photograph of a running faucet, can you tell if it is running hot or cold water? What new information does the IR image give you? The Infrared Zoo activities encourage learners to investigate the differences between warm and cold blooded animals by comparing sets of IR and visible images. In one activity, learners take on the role of a pit viper seeking prey in various desert and woodland settings. The main activities are extended into the real world by discussing and researching industrial, medical, and societal applications of infrared technologies. The Infrared Yellowstone lessons give learners a unique perspective on Yellowstone National Park and it's spectacular geologic and geothermal features. Infrared video technology is highlighted as learners make detailed observations about the visible and infrared views of the natural phenomena. The "Cool Cosmos" EPO activities are

This qualitative investigation extends the study of self-regulation to examine young children's developing self-regulated learning competencies. The framework for this research draws upon social cognitive, developmental, and sociocultural perspectives on self-regulation and research on children's scientific thinking. Taking a multiple case study approach, this study examines six kindergarten children's emerging self-regulatory competencies during inquiry-based science instruction. Data were collected during two inquiry-based science programs of study, one pertaining to light and shadow and a second pertaining to motion on inclined planes. Data sources included: videotaped records of the instruction, transcriptions of the videotapes, interviews with the children and teacher, student work, and field notes. Taking an inductive approach to analysis, patterns in the children's activity were identified through a recursive process of defining and refining categories that characterized the children's verbal and behavioral activity. Each case study examines a child's behavior within each phase of the inquiry for evidence of emerging self-regulatory competence. Analysis revealed nascent forms of goal-setting and planning, monitoring, resource management, seeking social assistance, and evaluating. Monitoring activity occurred more frequently than planning or evaluating. For several children, animating materials served to promote motivation. Children's efforts to support peers' activity and monitor the meaning of ongoing discourse contrast with common assumptions about children's attention to others' thinking. Variations in self-regulatory activity were found across phases of instruction. The children exhibited interpersonal self-regulatory efforts, in which monitoring and control of the self was entwined with the activity of others. Joint participation also played a critical role in supporting the metacognitive demands of self-regulation and prompting metacognitive awareness

Science education professionals generally agree that hands-on, inquiry-based science potentially benefits all students, yet there are few specific guidelines for helping students with learning disabilities (LD) achieve success in general education science classrooms. This study compared the effects of two approaches to hands-on science--supported inquiry science (SIS) and activity-based science--in six urban and two suburban fourth-grade general education classrooms. Participants included 172 students, 33 of whom had learning disabilities. The study found that students with and without LD demonstrated greater concept learning in the SIS classrooms, which focused on eliciting and reworking students' misconceptions and co-constructing knowledge under the guidance of a teacher-coach.

Many of the most important questions studied in science touch on fundamental issues with a great popular appeal, such as: How was the world created? How did life arise? Are we alone? How does it all end? Communication of science to the public is important and will play an even greater role in the coming years. The communication of achieved results is more and more often seen as a natural and mandatory activity to inform the public, attract funding, and attract science students. In some countries university statutes are even being rewritten in these years to include communication with the public as the third mandatory function besides research and education. A number of interesting "lessons learned" from the daily work at the Education and Outreach (EPO) office of the European Space Agency's Hubble Space Telescope will be presented. The topics include conventional as well as unconventional issues such as: • How does the flow of communication from scientist to public work, which actors are involved, and which pitfalls are present in their interaction? How can possible problems be avoided? • What are the criteria that determine whether press releases "make it" or not? • How can a commercial approach benefit an EPO office? • What is the right skills base in a modern EPO office? • How can modern technology be used to communicate science more efficiently?

Inquiry-based science teaching is an inductive approach to science instruction that originated in constructivist learning theory and requires students to be active participants in their own learning process. In an inquiry-based classroom, students actively construct their knowledge of science through hands-on, engaged practices and inquiry-based approaches. Inquiry-based teaching stands in contrast to more traditional forms of teaching that see students as empty vessels to be filled by the teacher with rote facts. Despite calls from the NSF, the NRC, and the AAAS for more inquiry-based approaches to teaching science, research has shown that many teachers still do not use inquiry-based approaches. Teachers have cited difficulties including lack of time, high-stakes testing, a shortage of materials, problems with school-wide logistics, rigid science curricula, student passivity, and lack of prerequisite skills. The objective of this mixed-methods study was to examine to what extent specific, identifiable personality traits contribute to the likelihood that a teacher will use inquiry in the science classroom, and what factors figure predominantly as teachers' reasons for implementing inquiry. The findings of the study showed that the null hypotheses were not rejected. However, reduced conscientiousness and increased openness may be significant in indicating why teachers use inquiry-based teaching methods and avenues for further research. In addition, the qualitative results aligned with previous findings that showed that lack of resources (e.g., time and money) and peer support act as powerful barriers to implementing inquiry-based teaching. Inquiry teachers are flexible, come to teaching as a second or third career, and their classrooms can be characterized as chaotic, fun, and conducive to learning through engagement. The study suggests changes in practice among administrators and teachers. With adjustments in methods and survey instruments, additional research

The Hands-On Optics project offers an example of a set of instructional modules that foster active prolonged engagement. Developed by SPIE, OSA, and NOAO through funding from the U.S. National Science Foundation, the modules were originally designed for afterschool settings and museums. However, because they were based on national standards in mathematics, science, and technology, they were easily adapted for use in classrooms. The philosophy and implementation strategies of the six modules will be described as well as lessons learned in training educators. The modules were implementing with the help of optics industry professionals who served as expert volunteers to assist educators. A key element of the modules was that they were developed around an understanding of optics misconceptions and used culminating activities in each module as a form of authentic assessment. Thus student achievement could be measured by evaluating the actual product created by each student in applying key concepts, tools, and applications together at the end of each module. The program used a progression of disciplinary core concepts to build an integrated sequence and crosscutting ideas and practices to infuse the principles of the modern electro-optical field into the modules. Whenever possible, students were encouraged to experiment and to create, and to pursue inquiry-based approaches. The result was a program that had high appeal to regular as well as gifted students.

Societal benefit depends on the general public's understandings of biotechnology (Betsch in World J Microbiol Biotechnol 12:439-443, 1996; Dawson and Cowan in Int J Sci Educ 25(1):57-69, 2003; Schiller in Business Review: Federal Reserve Bank of Philadelphia (Fourth Quarter), 2002; Smith and Emmeluth in Am Biol Teach 64(2):93-99, 2002). A National Science Foundation funded survey of high school biology teachers reported that hands-on biotechnology education exists in advanced high school biology in the United States, but is non-existent in mainstream biology coursework (Micklos et al. in Biotechnology labs in American high schools, 1998). The majority of pre-service teacher content preparation courses do not teach students appropriate content knowledge through the process of inquiry. A broad continuum exists when discussing inquiry-oriented student investigations (Hanegan et al. in School Sci Math J 109(2):110-134, 2009). Depending on the amount of structure in teacher lessons, inquiries can often be categorized as guided or open. The lesson can be further categorized as simple or authentic (Chinn and Malhotra in Sci Educ 86(2):175-218, 2002). Although authentic inquiries provide the best opportunities for cognitive development and scientific reasoning, guided and simple inquiries are more often employed in the classroom (Crawford in J Res Sci Teach 37(9):916-937, 2000; NRC in Inquiry and the national science education standards: a guide for teaching and learning, 2000). For the purposes of this study we defined inquiry as "authentic" if original research problems were resolved (Hanegan et al. in School Sci Math J 109(2):110-134, 2009; Chinn and Malhotra in Sci Educ 86(2):175-218, 2002; Roth in Authentic school science: knowing and learning in open-inquiry science laboratories, 1995).

This study examines Saudi Arabian middle school science textbooks' coverage of the essential features of scientific inquiry. All activities in the middle school science textbooks and workbooks were analyzed by using the scientific inquiry `essential features' rubric. The results indicated that the essential features are included in about 59 % of the analyzed science activities. However, feature 2, `making learner give priority to evidence in responding to questions' and feature 3, `allowing learner to formulate explanations from evidence' appeared more frequently than the other three features (feature 1: engaging learner in scientifically oriented questions, feature 4: helping learner connect explanations to scientific knowledge, and feature 5: helping learner communicate and justify explanations to others), whether in the activities as a whole, or in the activities included in each of the four science domains (physical science, Earth science, life science and chemistry). These features are represented in almost all activities. This means that almost all activities in the middle school science textbooks and the workbooks include features 2 and 3. Meanwhile, the mean level of inclusion of the five essential features of scientific inquiry found in the middle school science textbooks and workbooks as a whole is 2.55. However, results found for features 1, 4, 5 and for in-level inclusion of the inquiry features in each of the science domains indicate that the inclusion of the essential inquiry features is teacher-centred. As a result, neither science textbooks nor workbooks provide students with the opportunity or encouragement to develop their inquiry skills. Consequently, the results suggest important directions for educational administrators and policy-makers in the preparation and use of science educational content.

The purposes of this study were to (a) gain an understanding of the views of inquiry held by faculty members involved in undergraduate science teaching and (b) describe the challenges, constraints, and opportunities that they perceived in designing and teaching inquiry-based laboratories. Participants included 19 college professors, representing both life and physical science disciplines, from (a) 2-year community college, (b) small, private nonprofit liberal arts college, (c) public master's granting university, and (d) public doctoral/research extensive university. We collected data through semistructured interviews and applied an iterative data analysis process. College science faculty members held a full and open inquiry view, seeing classroom inquiry as time consuming, unstructured, and student directed. They believed that inquiry was more appropriate for upper level science majors than for introductory or nonscience majors. Although faculty members valued inquiry, they perceived limitations of time, class size, student motivation, and student ability. These limitations, coupled with their view of inquiry, constrained them from implementing inquiry-based laboratories. Our proposed inquiry continuum represents a broader view of inquiry that recognizes the interaction between two dimensions of inquiry: (a) the degree of inquiry and (b) the level of student directedness, and provides for a range of inquiry-based classroom activities.

From the late 1950s through today, hands-on science has been promoted as a method of science instruction. Currently, recent national science reform efforts seek to temper its role. However, no consensus has been reached on the relationship of hands-on science to student achievement though this topic has been researched since the turn of the 20th century using various methods. To improve upon the literature, this work addresses three major limitations of past research---the lack of data on performance assessments of student achievement, the need to control for factors affecting both hands-on science and test scores, and the potential for a differential relationship by student ability. This work focuses on three research questions: (1) whether hands-on science is positively related to student achievement as measured by standardized test scores using both multiple choice and performance tests, (2) whether this relationship is stronger when using performance tests, and (3) whether this relationship differs by student ability. We apply regression analysis to two data sources. The primary data set is the 1994 RAND Survey of 1400 8th grade students and their teachers in Southern California which includes multiple choice and performance test scores. A second data source is the nationally representative NELS:88 with a focus on the 8th grade student sample. The initial findings vary by source of report, student or teacher, on the level of hands-on science. When accounting for the quality of the reports, the results show an association between the level of handson science and student test scores for both multiple choice and performance tests. The results find little difference for this relationship by type of test. Nor do they show strong evidence for a differential relationship due to student ability. These findings support the promotion of hands-on science at the middle school/junior high level while raising a concern about current science reform attempts to reduce and

A long-term exposition focused on optics and photonics was created in Institute of Atomic Physics and Spectroscopy at University of Latvia in 2010. Considering unpopularity of science in Latvia and lack of broadly accessible hands-on outreach activities for school children, as well as rapid development of advanced photonic technologies, this exposition was meant to involve more students to the natural sciences and modern technologies. Exposition covers 10 topics of optics - colors, diffraction, interference, polarization, reflection, liquid crystals, gas discharge, lasers, fluorescence, infrared and ultraviolet radiation. Students' visits are organized as an exciting adventure, which differs from ordinary school lessons. The visit mainly includes own actions with hands-on exhibits, lecturer's explanations about the most difficult topics and some demonstrations shown by the lecturer. The main accent is made on hands-on experiments due to the fact that students, who had performed hands-on experiments, will be emboldened to choose their career in the field of science and technologies. The exposition now is running and is part of Riga Photonics Center. Nearly 300 students from the 8th till 12th grades visited it during academic years 2011/2012 and 2012/2013 and their generally positive feedback has been analyzed.

We compared learning cycle and expository formats for teaching about plant biodiversity in an inquiry-oriented university biology lab class (n = 465). Both formats had preparatory lab activities, a hands-on lab, and a postlab with reflection and argumentation. Learning was assessed with a lab report, a practical quiz in lab, and a multiple-choice exam in the concurrent lecture. Attitudes toward biology and treatments were also assessed. We used linear mixed-effect models to determine impacts of lab style on lower-order cognition (LO) and higher-order cognition (HO) based on Bloom's taxonomy. Relative to the expository treatment, the learning cycle treatment had a positive effect on HO and a negative effect on LO included in lab reports; a positive effect on transfer of LO from the lab report to the quiz; negative impacts on LO quiz performance and on attitudes toward the lab; and a higher degree of perceived difficulty. The learning cycle treatment had no influence on transfer of HO from lab report to quiz or exam; quiz performance on HO questions; exam performance on LO and HO questions; and attitudes toward biology as a science. The importance of LO as a foundation for HO relative to these lab styles is addressed.

Learning was assessed with a lab report, a practical quiz in lab, and a multiple-choice exam in the concurrent lecture. Attitudes toward biology and treatments were also assessed. We used linear mixed-effect models to determine impacts of lab style on lower-order cognition (LO) and higher-order cognition (HO) based on Bloom's taxonomy. Relative to the expository treatment, the learning cycle treatment had a positive effect on HO and a negative effect on LO included in lab reports; a positive effect on transfer of LO from the lab report to the quiz; negative impacts on LO quiz performance and on attitudes toward the lab; and a higher degree of perceived difficulty. The learning cycle treatment had no influence on transfer of HO from lab report to quiz or exam; quiz performance on HO questions; exam performance on LO and HO questions; and attitudes toward biology as a science. The importance of LO as a foundation for HO relative to these lab styles is addressed. PMID:25185232

NSF-funded GeoMapApp Learning Activities (http://serc.carleton.edu/geomapapp) provide self-contained learning opportunities that are centred around the principles of guided inquiry. The activities allow students to interact with and analyse research-quality geoscience data to explore and enhance student understanding of underlying geoscience content and concepts. Each activity offers ready-to-use step-by-step student instructions and answer sheets that can be downloaded from the web page. Also provided are annotated teacher versions of the worksheets that include teaching tips, additional content and suggestions for further work. Downloadable pre- and post- quizzes tied to each activity help educators gauge the learning progression of their students. Short multimedia tutorials and details on content alignment with state and national teaching standards round out the package of material that comprises each "grab-and-go" activity. GeoMapApp Learning Activities expose students to content and concepts typically found at the community college, high school and introductory undergraduate levels. The activities are based upon GeoMapApp (http://www.geomapapp.org), a free, easy-to-use map-based data exploration and visualisation tool that allows students to access a wide range of geoscience data sets in a virtual lab-like environment. Activities that have so far been created under this project include student exploration of seafloor spreading rates, a study of mass wasting as revealed through geomorphological evidence, and an analysis of plate motion and hotspot traces. The step-by-step instructions and guided inquiry approach lead students through each activity, thus reducing the need for teacher intervention whilst also boosting the time that students can spend on productive exploration and learning. The activities can be used, for example, in a classroom lab with the educator present and as self-paced assignments in an out-of-class setting. GeoMapApp Learning Activities

The purpose of this quasi-experimental study was to determine the effects on community college student physics conceptual achievement and attitudes about learning physics due to the use of inquiry-based laboratory activities versus cookbook laboratory activities. An analysis of covariance (ANCOVA) was performed to test for differences in mean post-test Force Concept Inventory (FCI) score for two different types of physics lab instruction (IL versus CBL). Results of the ANCOVA, F (1, 35) = 0.761, p < 0.389, supported the null hypothesis that no significant difference was found in the post-test FCI scores of the two groups. An ANCOVA was performed to test for differences in mean post-test Mechanics Baseline Test (MBT) score for two different types of physics lab instruction (IL versus CBL)., however, the covariate and the dependent variable were shown to not be linearly related. Therefore, a one-way analysis of variance (ANOVA) was used to compare MBT scores. The results of the ANOVA, F (1, 36) = 0.066, p < 0.798, supported the null hypothesis that there was no significant difference in MBT scores of the two groups. A step-wise multiple linear regression was used to analyze the relationships between the FCI post-test score and the type of instruction, FCI pre-test score, and American College Test (ACT) science reasoning sub-scores. The FCI pre-test score and ACT science score were shown to be the best predictors of FCI post-test score. Another step-wise multiple linear regression was used to analyze the relationships between the MBT post-test score and type of instruction, MBT pre-test score, and ACT science reasoning sub-scores. The ACT Science sub-scores were determined to be the best predictor of MBT post-test score. An independent t-test was used to compare the mean lecture test grades for the lab groups taught using inquiry and cookbook methods. The mean lecture test scores of the inquiry-based lab group (M = 81.39, S.D. = 8.15) were found to be significantly
Science and technology are widely recognized as major drivers of innovation and industry (e.g. Rising above the Gathering Storm, 2006). While the focus for education reform is on school improvement, there is considerable research that supports the role that out-of-school experiences can play in student achievement and public understanding of STEM disciplines. Libraries provide an untapped resource for engaging underserved youth and their families in fostering an appreciation and deeper understanding of science and technology topics. Designed spaces, like libraries, allow lifelong, life-wide, and life-deep learning to take place though the research basis for learning in libraries is not as developed as other informal settings like science centers. The Space Science Institute’s National Center for Interactive Learning (NCIL) in partnership with the American Library Association (ALA), the Lunar and Planetary Institute (LPI), and the National Girls Collaborative Project (NGCP) have received funding from NSF to develop a national education project called the STAR Library Education Network: a hands-on learning program for libraries and their communities (or STAR-Net for short). STAR stands for Science-Technology, Activities and Resources. The overarching goal of the project is to reach underserved youth and their families with informal STEM learning experiences. This project will deepen our knowledge of informal/lifelong learning that takes place in libraries and establish a learning model that can be compared to the more established free-choice learning model for science centers and museums. The project includes the development of two STEM hands-on exhibits on topics that are of interest to library staff and their patrons: Discover Earth and Discover Tech. In addition, the project will produce resources and inquiry-based activities that libraries can use to enrich the exhibit experience. Additional resources will be provided through partnerships with relevant

In this paper, we describe the design and implementation of an inquiry-based laboratory unit on the Polymerase Chain Reaction (PCR). This unit was designed and taught for the undergraduate Eukaryotic Genetics Laboratory class (Bio105L) at the University of California, Santa Cruz. Our activity utilizes an authentic molecular biology research question to teach the underlying molecular mechanisms and experimental technique of PCR, as well as fundamental scientific process skills such as planning experiments, making predictions and interpreting data. In particular, the activity prompts students to use PCR to determine which gene has been deleted in a region of the Drosophila genome. During this activity, students also gained technical experience in common molecular biology techniques, learned about additional applications of PCR and used a hands-on approach to model each step of PCR.

Developing students' skills to pose and respond to questions and actively engage in inquiry behaviours enables students to problem solve and critically engage with learning and society. The aim of this study was to analyse the impact of providing teachers with an intervention in inquiry pedagogy alongside inquiry science curriculum in comparison to an intervention in non-inquiry pedagogy alongside inquiry science curriculum on student questioning and other inquiry behaviours. Teacher participants in the comparison condition received training in four inquiry-based science units and in collaborative strategic reading. The experimental group, the community of inquiry (COI) condition, received training in facilitating a COI in addition to training in the same four inquiry-based science units. This study involved 227 students and 18 teachers in 9 primary schools across Brisbane, Australia. The teachers were randomly allocated by school to one of the two conditions. The study followed the students across years 6 and 7 and students' discourse during small group activities was recorded, transcribed and coded for verbal inquiry behaviours. In the second year of the study, students in the COI condition demonstrated a significantly higher frequency of procedural and substantive higher-order thinking questions and other inquiry behaviours than those in the comparison condition. Implementing a COI within an inquiry science curriculum develops students' questioning and science inquiry behaviours and allows teachers to foster inquiry skills predicated by the Australian Science Curriculum. Provision of inquiry science curriculum resources alone is not sufficient to promote the questioning and other verbal inquiry behaviours predicated by the Australian Science Curriculum.

A project has been started in 2005 to design innovative curriculum for the intro physics courses at McMurry University. The project is rooted in science education research and ideas from the NFW. The goal is to achieve better integration of traditional course components by means of instructional design and technology. First, a system of flexible curriculum modules with emphasis on inquiry-based teaching has been introduced. Second, technology is used to improve continuity among module components (lecture/lab/discussion) and stimulate active learning. Enabling technology suite incorporates Tablet PC's and software applications including java-based Physlets, tablet-adapted personal response systems, and PASCO data acquisition systems. Lab curriculum has been modified to accommodate for different learning styles, and levels of baseline knowledge. Activity options and pre-lab Physlet-based assignments were added. To enhance knowledge generalization, multiple experiments are used to illustrate different aspects of the same physics phenomenon. Physlet-based problems were adapted for student peer group discussions. Student feedback showed that modifications were beneficial. Student knowledge assessment, performed with the FCI test, indicated improvement in student learning.

While evolution education has received a great deal of attention within the science education research community it still poses difficult teaching and learning challenges. Understanding evolutionary biology has been given high priority in national science education policy because of its role in coordinating our understanding of the life sciences, its importance in our intellectual history, its role in the perception of humans' position in nature, and its impact on our current medical, agricultural, and conservation practices. The rhetoric used in evolution education policy statements emphasizes familiarity with the nature of scientific inquiry as an important learning outcome associated with understanding evolution but provide little guidance with respect to how one might achieve this goal. This dissertation project explores the nature of evolutionary inquiry and how understanding the details of disciplinary reasoning can inform evolution education. The first analysis involves recasting the existing evolution education research literature to assess educational outcomes related to students ability to reason about data using evolutionary biology methods and models. This is followed in the next chapter by a detailed historical and philosophical characterization of evolutionary biology with the goal of providing a richer context for considering what exactly it is we want students to know about evolution as a discipline. Chapter 4 describes the development and implementation of a high school evolution curriculum that engages students with many aspects of model based reasoning. The final component of this reframing of evolution education involves an empirical study characterizing students' understanding of evolutionary biology as a modeling enterprise. Each chapter addresses a different aspect of evolution education and explores the implications of foregrounding disciplinary reasoning as an educational outcome. The analyses are coordinated with one another in the sense

The GLOBE Program (www.globe.gov) engages K-12 students through scientific discovery to learn about the Earth as a system and provides a curricular example for the Next Generation Science Standards (NGSS). A key component of GLOBE is its inquiry-based, hands-on activities, which align with the eight practices found in Dimension 1 of the Standards. GLOBE teachers currently address the crosscutting concepts from Dimension 2 in the Standards by engaging students in data analysis and application through GLOBE Investigations, such as GPS, hydrology and atmosphere. Hands-on activities align to the disciplinary core ideas of Dimension 3 of the Standards through the implementation of protocols in air, water, soil, land cover, and seasons in over 25,000 schools in more than 110 countries worldwide. Integration of technology, engineering, and the application of science have played a central role in The GLOBE Program since its inception in 1995. The GLOBE Program provides a venue for students to report their own scientific investigations to scientists, teachers, and other students through student research reports, as well as a variety of student conference opportunities. This presentation will provide samples of how The GLOBE Program and GLOBE teachers encourage inquiry-based learning for student achievement of the NGSS through the review of student reports. These reports serve as artifacts illustrating the scientific practices, crosscutting concepts, and disciplinary core ideas students engage in while participating in GLOBE. This review will illustrate the extent to which GLOBE protocols and activities support NGSS, indicate gaps or mismatches in scope and sequence, provide recommendations for new materials development, and demonstrate a process that can be repeated by other science education programs to review their own current alignment to NGSS.

Research into the process of learning, and learning astronomy, can be informative for the development of a course. Students are better able to incorporate and make sense of new ideas when they are aware of their own prior knowledge (Resnick et al. 1989; Confrey 1990), have the opportunity to develop explanations from their own experience in their own words (McDermott 1991; Prather et al. 2004), and benefit from peer instruction (Mazur 1997; Green 2003). Students in astronomy courses often have difficulty understanding many different concepts as a result of difficulties with spatial reasoning and a sense of scale. The Hands-on-Science program at UT Austin incorporates these research-based results into four guided-inquiry, integrated science courses (50 students each). They are aimed at pre-service K-5 teachers but are open to other majors as well. We find that Hands-on-Science students not only attain more favorable changes in attitude towards science, but they also outperform students in traditional lecture courses in content gains. Workshop Outcomes: Participants experienced a research-based, guided-inquiry lesson about the motion of objects in the sky and discussed the research methodology for assessing students in such a course.

The current vision of science education in myriad educational contexts encourages students to learn through the process of science inquiry. Science inquiry has been used to promote conceptual learning and engage learners in an active process of meaning-making and investigation to understand the world around them. The science inquiry process typically involves asking questions and defining problems; constructing explanations and designing solutions; planning and carrying out investigations; analyzing and interpreting data; and engaging in argument from evidence. Despite the importance and provision of new directions and standards about science inquiry, ambiguities in conceptualizations of inquiry still exist. These conceptualizations may serve as barriers to students learning science. In this article, we detail three main concerns related to teachers' conceptualization of science inquiry in the context of a Singapore classroom—concerns that may be similarly faced by teachers elsewhere.

At the core of the movement for twenty-first century skills are students. The growing efforts to increase programs leveraging out-of-school time are focused on giving American youth everything they need to compete in this increasingly complex world. The author is one of many students who have been well served by initiatives imparting twenty-first century skills during after-school hours. Now a senior at Boston Latin School, the author has been helped along the way by Citizen Schools, an after-school education program focused on hands-on learning apprenticeships and homework help. While enrolled in the program as a middle school student, the author took part in projects that exemplified hands-on, inquiry-based learning that helped her develop twenty-first century skills. For example, along with dozens of other students, she advanced her data analysis skills by analyzing statistics about Boston Public high schools, which also helped her select and enroll in one of the city's premier exam schools. Also, she and her peers worked with corporate attorneys who served as writing coaches and whose expertise the author drew from in producing a published essay and greatly improving her writing skills. The author now finds that the public speaking, leadership, organizational, social, and management abilities she built through her participation in Citizen Schools are a great asset to her in high school. The confidence with which she tackles her responsibilities can also be traced back to her experiences in the program. As she looks toward college, the author reflects and realizes that being actively involved in a quality after-school program put her on track for a successful future.

The Minority Access to Research Careers (MARC) and Minority Biomedical Research Support (MBRS) are programs at the University of California at Santa Cruz designed to support minority undergraduate students majoring in the sciences. Each summer MARC/MBRS sponsors a Summer Institute that involves week long "rotations" with different faculty mentors. In 2008, the Center for Adaptive Optics (CfAO) Professional Development Program (PDP) was responsible for overseeing one week of the Summer Institute, and designed it to be a Biomedical Short Course. As part of this short course, we designed a four-hour activity in which students collected their own data and explored relationships between the basic biomolecules DNA, RNA, and protein. The goal was to have the students use experimental data to support their explanation of the "Central Dogma" of molecular biology. Here we describe details of our activity and provide a post-teaching reflection on its success.

The effects of the level of inquiry of situated secondary science laboratory activities on students' understanding of concepts and the nature of science, ability to use process skills and attitudes toward problem solving
Dana, Lisa Ann
Although there has been over thirty years of studies on the effects of inquiry-based science instruction on students' understanding of concepts and the nature of science, ability to use process skills, and attitudes toward problem solving and subsequent meta-analyses of these studies, little is conclusive because of the inability of researchers to adequately describe the various levels of inquiry-based science instruction being utilized. In many of these past studies inquiry-based science instruction was vaguely defined. Past descriptions of inquiry have mainly focused on the teacher vs. student responsibility in the parts of a laboratory activity (Herron 1971, Pella, 1961, and Schwab, 1962) and although others have since focused on other various aspects (Luft, 1999; Priestley, Priestley, Sutman, Schumuckler, Hilosky, & White 1998), none have been complete in scope to describe the classroom interactions between teacher and student, before, during and after manipulation of laboratory materials and to clearly define the various levels of inquiry-based science instruction occurring in a classroom. Utilizing some of these previous theoretical frameworks, this study created the Situated Laboratory Activity Instrument (SLAI) that clearly defines various levels of inquiry based upon specific categories of teacher-student behaviors. The term, situated laboratory activities, more clearly represents the time before, during and after the actual manipulation of material. Validity and reliability were established for the SLAI. The instrument was derived from both historical and current instruments for looking at inquiry. The data for the creation and revision of this instrument were collected through initial reliability measures and observing the situated laboratory activities in four secondary physics classrooms during the study. The SLAI was utilized in a preliminary study in a public high school of the effects of various levels of inquiry teaching on students' understanding

An important aspect of developing science literacy for all students is developing science-literate teachers. With the implementation of the No Child Left Behind Act, many middle school teachers found themselves in a position where they were no longer qualified to teach middle school science. This study was designed to help science teachers increase their science content knowledge, identify and resolve misconceptions/errors they may have, and assist them in their teaching by providing strategies for inquiry-based teaching, science laboratory exercises, and science equipment. Teachers enrolled in biology courses offered by the Rocky Mountain Middle School Math and Science Partnership participated in this study. They were required to take pre-, post-, and follow-up assessments over course concepts, complete a survey over their background and teaching pedagogy, and be observed teaching in their classrooms for three class periods followed by an interview after each observation. The results included key findings: (1) These assessments indicated that science teachers can increase their science content knowledge by attending high-quality professional development courses designed to help increase basic science content knowledge on science content. (2) Teachers held numerous misconceptions as shown by the assessments and classroom observations. Some were resolved, some that appeared to be resolved at the time of the post test reappeared again on the follow-up test, and some were not resolved. (3) Teacher observations showed that they did use science equipment provided by the course instructors and they taught the content from the Biology course where appropriate. Teachers teaching classes other than biology demonstrated their ability to teach inquiry science by employing inquiry activities and teaching with a "scientific method" approach.

By the time students are ready to enter the workforce they have been exposed to up to 20 years of ergonomics risk factors. As technology evolves, it provides more opportunities for intensive repetitive motion and with computers, cell phones, personal digital assistants (PDAs), and electronic games. The average student engages in fewer active physical activities, sit stationary in mismatched furniture in schools for hours and carry heavy backpacks. While long-term effects remain to be identified, increasingly ergonomists and others concerned with musculoskeletal health and wellness, see a need for early ergonomics education. This interactive session provides a hands-on approach to introducing ergonomics to students. Although different approaches may effectively introduce ergonomics at even early stages of development, this program was designed for youth at the middle to high school age. Attendees will participate in four activities designed to introduce ergonomics at an experiential level. The modules focus on grip strength, effective breathing, optimizing your chair, and backpack safety. The workshop will include presentation and worksheets designed for use by teachers with minimal ergonomics training. Feedback from the participants will be sought for further refining the usability and safety of the training package.

To describe an inquiry-based learning activity and discuss the advantages of using such activities to demonstrate research design to undergraduate psychology students the authors presented students with the research problem of eyewitness memory recall and asked students to solve the problem, using the information provided by the course. Working in small groups, students reviewed eyewitness studies and designed their own research materials, including a videotaped theft and a CD-ROM version of the eyewitness survey and potential suspect line-up. Poststudy interviews showed that the students enjoyed the activity and felt that they had a better understanding of experimental research design than they had before the exercise. It is proposed that this activity may be a useful hands-on tool for instructors who have difficulty teaching students fundamental topics such as literature reviews, hypothesis testing, reliability and validity of research measures, and experimental design.

The present study reports the elaboration, application and evaluation of a problem-based learning (PBL) program that aims to evaluate the effectiveness in students learning the Rock Cycle theme. Prior research on both PBL and Rock Cycle was conducted within the context of science education so as to elaborate and construct the intervention program. Findings from these studies indicated both the PBL methodology and Rock Cycle as helpful for teachers and students. PBL methodology has been adopted in this study since it is logically incorporated in a constructivism philosophy application and it was expected that this approach would assist students towards achieving a specific set of competencies. PBL is a student-centered method based on the principle of using problems as the starting point for the acquisition of new knowledge. Problems are based on complex real-world situations. All information needed to solve the problem is initially not given. Students will identify, find, and use appropriate resources to complete the exercise. They work permanently in small groups, developing self-directed activities and increasing participation in discussions. Teacher based guidance allows students to be fully engaged in knowledge building. That way, the learning process is active, integrated, cumulative, and connected. Theme "Rock Cycle" was introduced using a problematic situation, which outlined the geological processes highlighted in "Foz do Douro" the next coastline of the school where the study was developed. The questions proposed by the students were solved, using strategies that involved the use of hands-on activities and virtual labs in Geology. The systematization of the selected theme was performed in a field excursion, implemented according to the organizational model of Nir Orion, to The "Foz do Douro" metamorphic complex. In the evaluation of the learning process, data were obtained on students' development of knowledge and competencies through the application of

teachers to convey moderately complex computer science, optical, geographic, mathematical, informational and physical principles through hands-on telescope operations. In addition to the general studies aspects of classroom internet-based astronomy, Tzec Maun supports real science by enabling operators precisely point telescopes and acquire extremely faint, magnitude 19+ CCD images. Thanks to the creative Team of Photometrica (photometrica.org), my teams now have the ability to process and analyze images online and produce results in short order. Normally, astronomical data analysis packages cost greater than thousands of dollars for single license operations. Free to my team members, Photometrica allows students to upload their data to a cloud computing server and read precise photometric and/or astrometric results. I’m indebted to Michael and Geir for their support. The efficacy of student-based research is well documented. The Council on Undergraduate Research defines student research as, "an inquiry or investigation conducted by an undergraduate that makes an original intellectual or creative contribution to the discipline." (http://serc.carleton.edu/introgeo/studentresearch/What. Teaching from Tzec Maun in the classroom is the most original teaching research I can imagine. I very much look forward to presenting this program to the convened body.

In the Society of our days there is a major increasing need of an in depth quality education in Science and Technology. Science teaching at school should be generalized aiming not only the sound establishment of a "Science" culture in our societies but also to guarantee a steady basis for the improvement of Science and its technological applications. The European Commission, under the program Socrates, Comenus 3 action (project n°. 110157-CP-1-2003-1-PT-COMENIUS-C3) supports the network "Hands-on Science". The activities of our network focus on the development and or diffusion at European scale of positive hands-on experimental practices on teaching science at basic secondary and vocational training schools, by leading the students to an active volunteer and committed participation in the teaching/learning process through hands-on practice and experimentation, making intensive use of the new instruments and resources of the Information Society.

Collaborative inquiry learning is one of the most challenging and exciting ventures for today's schools. It aims at bringing a new and promising culture of teaching and learning into the classroom where students in groups engage in self-regulated learning activities supported by the teacher. It is expected that this way of learning fosters students' motivation and interest in science, that they learn to perform steps of inquiry similar to scientists and that they gain knowledge on scientific processes. Starting from general pedagogical reflections and science standards, the article reviews some prominent models of inquiry learning. This comparison results in a set of inquiry processes being the basis for cooperation in the scientific network NetCoIL. Inquiry learning is conceived in several ways with emphasis on different processes. For an illustration of the spectrum, some main conceptions of inquiry and their focuses are described. In the next step, the article describes exemplary computer tools and environments from within and outside the NetCoIL network that were designed to support processes of collaborative inquiry learning. These tools are analysed by describing their functionalities as well as effects on student learning known from the literature. The article closes with challenges for further developments elaborated by the NetCoIL network.

In this thesis, we investigate an informal after-school science program. We examine two inquiry curricula used in this program; one more guided and the other more open. We have developed new methods to analyze middle school children's scientific notebooks, and we measure how the children exhibit agency, how the children communicate, and the mechanistic reasoning children use. We compare the two curricula and find that the children exhibit more agency in the open curriculum, write and draw more in the open curriculum, demonstrate a wide variety of scientific communication, and use more varied types of mechanistic reasoning in the open curriculum. These aspects can be linked to science identity, and we conclude that the more open curriculum supports the development of positive science identity.

The power of music to resonate within us transcends conventional boundaries established in cultural, geographic, and political contexts. In our world, as physics educators, so does the resonating of physics phenomena. Secondary level physics is a perfect place to blend these two genres. While advocating for STEM-based education is at the forefront of pedagogical reform, seldom do we use this cross-boundary vision as the foundation to teach and learn in true collaboration of science and arts classrooms. As music enthusiasts, and physics educators, we developed new resources for a blended music and physics class through inquiry-based learning activities. Punctuated with modern technology, we aimed our activities for an engaging learning experience towards developing conceptual understandings of sound and harmonics at the grade 11 level. The umbrella activity shared here was designed to engage a wide range of students through the universal language of music, and provide them a hands-on and minds-on experience to explore harmonics through both music and physics lenses. It is our intention to provide readers with an overview of the activity, a description of exemplar student-designed inquiry-based investigations, and helpful suggestions for potential for use in reader’s classrooms.

The use of virtual laboratories has the potential to change physics education. These low-cost, interactive computer activities interest students, allow for easy setup, and give educators a way to teach laboratory based online classes. This study investigated whether virtual laboratories could replace traditional hands-on laboratories and whether students could retain the same long-term knowledge in virtual laboratories as compared to hands-on laboratories. This study is a quantitative quasi-experiment that used a multiple posttest design to determine if students using virtual laboratories would retain the same knowledge as students who performed hands-on laboratories after 9 weeks. The study was composed of 336 students from 14 school districts. Students had their performances on the laboratories and their retention of the laboratories compared to a series of factors that might have affected their retention using a pretest and two posttests, which were compared using a t test. The results showed no significant difference in short-term learning between the hands-on laboratory groups and virtual laboratory groups. There was, however, a significant difference (p = .005) between the groups in long-term retention; students in the hands-on laboratory groups retained more information than those in the virtual laboratory groups. These results suggest that long-term learning is enhanced when a laboratory contains a hands-on component. Finally, the results showed that both groups of students felt their particular laboratory style was superior to the alternative method. The findings of this study can be used to improve the integration of virtual laboratories into science curriculum.

Integration of technology ( e.g. measuring with sensors, video measurement, and modeling) into secondary-school science teaching is a need globally recognized. A central issue of incorporating these technologies in teaching is how to turn manipulations of equipment and software into manipulations of ideas. Therefore, preparation for pre-service teachers to apply ICT tools should be combined with the issues of minds-on inquiring and meaning-making. From this perspective, we developed a course within the post-graduate teacher-education program in the Netherlands. During the course, pre-service teachers learnt not only to master ICT skills but also to design, teach, and evaluate an inquiry-based lesson in which the ICT tool was integrated. Besides three life sessions, teachers' learning scenario also consisted of individual tasks which teachers could carry out mostly in the school or at home with support materials and online assistance. We taught three iterations of the course within a design-research framework in 2013, 2014 and collected data on the teacher learning processes and outcomes. The analyses of these data from observation, interviews, questionnaires, and documents were to evaluate implementation of the course, then suggest for revisions of the course set-up, which was executed and then assessed again in a subsequent case study. Main outcomes of the three case studies can be summarized as follows: within a limited time (3 life sessions spread over 2-3 months), the heterogeneous groups of pre-service teachers achieved a reasonable level of competence regarding the use of ICT tools in inquiry-based lessons. The blended set-up with support materials, especially the Coach activities and the lesson-plan form for an ICT-integrated inquiry-based lesson, contributed to this result under the condition that the course participants really spent considerable time outside the life sessions. There was a need for more time for hands-on, in-group activities in life

The Adler Planetarium's "Far Horizons" high-altitude ballooning effort serves as the focus for a diverse set of educational activities, including middle school summer camps, a high school summer program (the Astro-Science Workshop), school-year internships for high school students, summer internships for undergraduates, a NSF-funded graduate fellowship, and a thriving public volunteer program. The relatively low costs of both the reusable hardware (less than $1000) and expendable supplies (around $150 per launch) allow us to mount frequent missions throughout the year - and make such a program ideal for replication at institutions of any size. The rapid development schedule for each individual mission permits the cradle-to-grave involvement of short-term participants, making it easy to draw in a wide audience. Students are involved literally in a hands-on manner in all aspects of the construction, launch, tracking, and recovery of simple experimental payloads, which typically include sensors for temperature, pressure, light intensity, and radiation. Stunning imagery provided by onboard cameras can attract significant media interest, which can bring outreach efforts to a very broad audience. Future plans include the design and construction of CubeSats - decimeter-sized picosatellites carried to orbit as secondary payloads. Our first satellite will be a relatively simple Earth-imager, built from commercial, off-the-shelf components. As in the ballooning program, students and volunteers will be involved in all stages of this effort. Once operational, imagery and other data from the satellite will be incorporated into a museum exhibit that will allow visitors to submit target requests. This material is based in part upon work supported by the National Science Foundation under Grant No. 0525995.

Hands-On Optics (HOO) was funded by the National Science Foundation Informal Science Education program to bring optics education to traditionally underserved middle school students. We developed a series of six optics modules each covering a different topic in optics. During the four-year grant, we brought the program to the Mathematics, Science and Engineering Achievement (MESA) programs in seven states as well as 8 major science centers. We continue to support our established sites as well as expand our program. One of our expansion efforts involves continuing our partnership with the International Society for Optical Engineering (SPIE). We have been working closely with SPIE to present workshops for student chapter leaders at SPIE meetings. The student chapter leaders use HOO materials in their outreach activities. SPIE has teamed with us to bring HOO to Europe. We have received a grant from the Science Foundation of Arizona to expand HOO in Arizona. This program builds on our successful programs at the South Tucson Boys and Girls Club as well as the Sells Boys and Girls Club by expanding HOO to other sites around the state with an emphasis on rural locations such as Bisbee, Safford, Prescott Valley and the Tohon O'odham Nation. We have been working with a variety of Boys and Girls Clubs around the state. Several programs are underway and we hope to add more sites in the coming year. We continue to host local events at Kitt Peak National Observatory as well as special events for the community and students in the Tucson area. Our events include science nights at local schools, optics festivals and competitions, career days and teacher fairs. We will describe the current state of the program as well as lessons learned as we expand the program in a variety of settings.

Hands On Optics and Informal Science Education PartnershipsHands-On Optics (HOO) is a collaborative four-year program to create and sustain a unique, national, informal science education program to excite students about science by actively engaging them in optics activities. Key partners in the project are NOAO, SPIE-The International Society for Optical Engineering, and the Optical Society of America (OSA). A vital component of HOO is the partnerships that are being formed with a variety of science centers around the country. We will describe the current partnerships with science centers and the current impact of the programs. We will also describe the challenges of integrating Hands On Optics into existing science center programs. Science centers have different needs than traditional classroom teachers and we will discuss the lessons learned from our science center programs. Our current partners include the New York Hall of Science, the Adventure Science Center, the Orlando Science Center and the Maryland Science Center. We are expanding our efforts to include smaller science and nature centers by partnering Astronomical Society of the Pacific’s program, Astronomy From the Ground Up (AFGU). AFGU will train staff members from 300 small to medium science and nature centers over the next three years, all of which will include some HOO materials.The Hands On Optics Project is funded by the National Science Foundation ISE program. NOAO is operated by the Association of Universities for Research in Astronomy (AURA), Inc. under cooperative agreement with the National Science Foundation.

We designed a 2-day inquiry activity where students learned about error analysis and coding practices in Python. Inquiry-based lessons provide students with opportunities to independently investigate scientific concepts and tools. A general structure is developed ahead of time and minimal, careful guidance provided during the activity, but students are given as much freedom as possible to explore the concepts at their own pace. We designed our activity to help students learn to write flexible, re-usable, and readable code. I will describe the lesson structure we initially designed, as well as what aspects worked for our students (or didn't) and our experience leading the activity.

The Laboratorio Didattica e Divulgazione Scientifica of the Istituto Nazionale di Geofisica e Vulcanologia (INGV's Educational and Outreach Laboratory) organized activity with kids to convey scientific knowledge and to promote research on Earth Science, focusing on volcanic and seismic hazard. The combination of games and learning in educational activity can be a valuable tool for study of complex phenomena. Hands-on activity may help in engage kids in a learning process through direct participation that significantly improves the learning performance of children. Making learning fun motivate audience to pay attention on and stay focused on the subject. We present the experience of the hand-on laboratory "Laboratorio goloso per bambini curiosi di scienza (a delicious hands-on laboratory for kids curious about science)", performed in Frascati during the 2013 European Researchers' Night, promoted by the European Commission, as part of the program organized by the Laboratorio Didattica e Divulgazione Scientifica in the framework of Associazione Frascati Scienza (http://www.frascatiscienza.it/). The hand-on activity were designed for primary schools to create enjoyable and unusual tools for learning Earth Science. During this activity kids are involved with something related to everyday life, such as food, through manipulation, construction and implementation of simple experiments related to Earth dynamics. Children become familiar with scientific concepts such as composition of the Earth, plates tectonic, earthquakes and seismic waves propagation and experience the effect of earthquakes on buildings, exploring their important implications for seismic hazard. During the activity, composed of several steps, participants were able to learn about Earth inner structure, fragile lithosphere, waves propagations, impact of waves on building ecc.., dealing with eggs, cookies, honey, sugar, polenta, flour, chocolate, candies, liquorice sticks, bread, pudding and sweets.

Ergonomics risk factors apply to everybody. Numerous adults have experienced disabling injuries related to use of computers and other forms of technology. Now children are using technology even more than adults. Increasingly ergonomics risk factors are being recognized as present in the world of children. Outreach to schools and the surrounding community by employers may help protect the future work force. A growing body of researchers believe that children can benefit from the early introduction of ergonomics awareness and preventative measures. While individual representatives of the educational system may embrace the concept of introducing ergonomics into the classroom, a number of barriers can prevent implementation of integrated programs. Some of the barriers to introducing ergonomics in schools have been absence of a tie to educational standards, the existing demands on teaching hours, and the absence of easily executable lesson plans. Ergonomics is rarely included in teacher training and professional ergonomics expertise is needed for the development of a class-based program. As part of Strategic Vision plan for 2025, a National Laboratory identified community outreach and the future workforces as key areas for initiatives. A series of hands-on interactive modules have been developed by professional ergonomics specialists. They are being tested with elementary, middle and high school students. Where possible, the content has been tied to the educational standards in the State of California in the USA. Currently the modules include grip strength, effective breathing, optimal keyboard and mouse positions, optimizing chairs, posture and movement, backpack safety and safe lifting. Each module takes the students through a related activity or experience. An individual worksheet asks them questions about the experience and guides them to consider implications in their activities of daily living. A module on hearing is under development.

As part of newly funded initiative, the Wolfson OpenScience Laboratory, we are linking a tool for inquiry based learning, nQuire (http://www.nquire.org.uk) with the virtual microscope for Earth science (http://www.virtualmicroscope.co.uk) to allow students to undertake projects and gain from inquiry based study thin sections of rocks without the need for a laboratory with expensive petrological microscopes. The Virtual Microscope (VM) was developed for undergraduate teaching of petrology and geoscience, allowing students to explore rock hand specimens and thin sections in a browser window. The system is based on HTML5 application and allows students to scan and zoom the rocks in a browser window, view in ppl and xpl conditions, and rotate specific areas to view birefringence and pleochroism. Importantly the VM allows students to gain access to rare specimens such as Moon rocks that might be too precious to suffer loss or damage. Experimentation with such specimens can inspire the learners' interest in science and allows them to investigate relevant science questions. Yet it is challenging for learners to engage in scientific processes, as they may lack scientific investigation skills or have problems in planning their activities; for teachers, managing inquiry activities is a demanding task (Quintana et al., 2004). To facilitate the realization of inquiry activities, the VM is being integrated with the nQuire tool. nQuire is a web tool that guides and supports students through the inquiry process (Mulholland et al., 2011). Learners are encouraged to construct their own personally relevant hypothesis, pose scientific questions, and plan the method to answer them. Then, the system enables users to collect and analyze data, and share their conclusions. Teachers can monitor their students' progress through inquiries, and give them access to new parts of inquiries as they advance. By means of the integration of nQuire and the VM, inquiries that involve collecting data

Land snails are common invertebrates that fascinate children. Unfortunately, they are seldom used for activities in the science classroom. Snails are inexpensive, take up little space in the classroom, and require only low maintenance, and their learning dividends can be enormous. For example, students can use them in inquiry-based activities that…

The purpose of this research was to examine the effects of summer science enrichment on eighth-graders' science process skills knowledge, attitude toward science and perceptions of scientists. A single group pre- and post-test design was used to test participants in a summer science enrichment camp, which took place over a three-week period in the summer of 2000. Participants, all of whom were residents of the Mississippi area known as the Delta, lived on the campus of Mississippi Valley State University for the entire course of the camp. Activities included several guided inquiry-based projects such as water rocket design and solar or battery-powered car design. Participants also took trips to an environmental camp in north Mississippi and to the Stennis Space Center on the Mississippi Gulf Coast. Participants worked on their projects in groups, supervised by an undergraduate student "mentor". Participants were encouraged to keep journals of their experiences throughout the camp, and the researcher developed a rubric to evaluate student journals for process knowledge, evidence of planning, reflective thought, and disposition toward science. Tests were used to evaluate student knowledge of process skills, attitude toward science, and perceptions of scientists. On the Test of Integrated Process Skills (Dillashaw & Okey, 1983), the students showed significant improvement overall, but when evaluated separately, males showed significant improvement while females did not. On the Attitude toward Science in School Assessment (Germane, 1988), data indicated that attitude toward science improved significantly for the group as a whole, but upon closer inspection, indicated a significant improvement for the female students only. On Chamber's Draw-a-Scientist Test (1983), analysis of student drawings indicated no significant change in stereotypical images of scientists for the group overall. However, boys' scores indicated a significant improvement when analyzed separately

Hydrological and geomorphologic characteristics of local watersheds are being investigated by undergraduate students in different Geoscience classes at California University of Pennsylvania. Local stream assessments, water quality monitoring, assessment of drinking water supply, non-point source pollution, stream bank erosion, mass wasting, environmental impact of different land use practices are among topics of laboratory reports, individual and group course long projects of students in the Department of Earth Sciences at California University of Pennsylvania. These projects have two folded educational benefits. Students gain unique educational opportunities being involved into service-learning projects, residents of the community are being educated as students present results of their studies on the website and in the Newsletter. Local environmental groups benefit from students projects as student contribute their time to organizational activities, collect and analyze data, make recommendations, propose future study designs, and staying involved with organizations as officers after the course of study or though internship programs. This paper will present several examples of inquiry-based hands-on educational opportunities conducted by students within local watersheds in Southwestern Pennsylvania.

The Department of Neuroscience at the University of Minnesota and the Science Museum of Minnesota have developed and implemented a successful program for middle school (grades 5-8) science teachers and their students, called Brain Science on the Move. The overall goals have been to bring neuroscience education to underserved schools, excite students about science, improve their understanding of neuroscience, and foster partnerships between scientists and educators. The program includes BrainU, a teacher professional development institute; Explain Your Brain Assembly and Exhibit Stations, multimedia large-group presentation and hands-on activities designed to stimulate student thinking about the brain; Class Activities, in-depth inquiry-based investigations; and Brain Trunks, materials and resources related to class activities. Formal evaluation of the program indicated that teacher neuroscience knowledge, self-confidence, and use of inquiry-based strategies and neuroscience in their classrooms have increased. Participating teachers increased the time spent teaching neuroscience and devoted more time to "inquiry-based" teaching versus "lecture-based teaching." Teachers appreciated in-depth discussions of pedagogy and science and opportunities for collegial interactions with world-class researchers. Student interest in the brain and in science increased. Since attending BrainU, participating teachers have reported increased enthusiasm about teaching and have become local neuroscience experts within their school communities.

Society becomes increasingly dependent on photonics technologies; however there is an alarming lack of technological awareness among secondary school students. They associate photonics with experiments and components in the class room that seem to bear little relevance to their daily life. The Rocard Report  highlights the need for fostering students' scientific skills and technological awareness and identifies inquiry based learning (IBL) as a means to achieve this. Students need to actively do science rather than be silent spectators. The `Photonics Explorer' kit was developed as an EU funded project to equip teachers, free-of-charge, with educational material designed to excite, engage and educate European secondary school students using guided inquiry based learning techniques. Students put together their own experiments using up-to-date versatile components, critically interpret results and relate the conclusions to relevant applications in their daily life. They work hands-on with the material, thus developing and honing their scientific and analytical skills that are otherwise latent in a typical class room situation. A qualitative and quantitative study of the impact of the kit in the classroom was undertaken with 50 kits tested in 7 EU countries with over 1500 students in the local language. This paper reports on the results of the EU wide field tests that show the positive impact of the kit in raising the self-efficacy, scientific skills and interest in science among students and the effectiveness of the kit in implementing IBL strategies in classrooms across EU.

Astronomy and space sciences have always been instrumental in attracting young students to physical sciences. While the lectures/demonstrations and exhibitions pertaining to space sci-ences capture the imagination of young students, these alone are not sufficient to induce them to join scientific research. In countries like India, where a large number of students take to physical sciences for under-graduate education, complex sociological factors are key issues in translating this large body of students to potential researchers. While lectures and exhibition lead to an increase in scientific awareness for these students, these do not give a feel for scien-tific research and bridge the gap between high school/college science education and high end research. In this context, a hands-on approach to astronomy education, in science research environments or closely connected to scientific institutions, offers a promising alternative. This approach has been used in optical astronomy, where inexpensive small telescopes are available, often coupling a vast network of amateur astronomy clubs to leading astronomy institutes. The non-visual and relatively more technical nature of radio astronomy has limited a similar approach in past for connecting students to space sciences using radio waveband. The tech-nological explosion in communication industry and radio connectivity in the last decade along with an expansion in engineering education makes this possible now using a hands-on approach in teaching radio astrophysics. In this presentation, the sociological factors affecting the student choice are discussed followed by a review of the efforts to bridge the above mentioned gap by various groups in the world in the last decade with a view to enumerate the best practices in a hands-on approach. A program using this approach at National Center for Radio Astrophysics is described, where the students are exposed to simple hands-on radio astronomy experiments such as spectral line
Recent initiatives in the laboratory curriculum have encouraged an inquiry-based approach to learning and teaching in the laboratory. It has been argued that laboratory instruction should not just be hands-on, but it should portray the essence of inquiry through the process of experiential learning and reflective engagement in collaboration with peers and in facilitation by the instructor. A student-centered active learning approach may be an effective way to enhance student understanding of concepts in the laboratory. The dissertation research work explores the impact of laboratory instruction and its relevance for college-level chemistry. Each chapter is different from the preceding chapter in terms of the purpose of the study and the research questions asked. However, the overarching idea is to address the importance of guided-inquiry based laboratory instruction in chemistry and its relevance in helping students to make connections with the chemistry content and in imparting skills to students. Such skills include problem solving, collaborative group work and critical thinking. The first research study (Chapter 2) concerns the impact of first year co-requisite general chemistry laboratory instruction on the problem-solving skills of students. The second research study (Chapter 3) examines the impact of implementing student roles also known as Student-Led Instructor Facilitated Guided-Inquiry based Laboratories, SLIFGIL) by modifying the Science Writing Heuristic approach of laboratory instruction. In the third research study (Chapter 4), critical thinking skills of first semester general chemistry laboratory students were compared to advanced (third or fourth year) chemistry laboratory students based on the analysis of their laboratory reports.

The University of South Florida, College of Marine Science Oceans: GK-12 Teaching Fellowship Program is successfully enriching science learning via the oceans. Funded by the National Science Foundation, the program provides a unique opportunity among scientists and K-12 teachers to interact with the intention of bringing ocean science concepts and research to the classroom environment enhance the experience of learning and doing science, and to promote `citizen scientists' for the 21st century. The success of the program relies heavily on the extensive summer training program where graduate students develop teaching skills, create inquiry based science activities for a summer Oceanography Camp for Girls program and build a relationship with their mentor teacher. For the last year and a half, two graduate students from the College of Marine Science have worked in cooperation with teachers from the Pinellas county School District, Southside Fundamental Middle School. Successful lesson plans brought into a 6th grade Earth Science classroom include Weather and climate: Global warming, The Geologic timescale: It's all about time, Density: Layering liquids, and Erosion processes: What moves water and sediment. The school and students have benefited greatly from the program experiencing hands-on inquiry based science and the establishment of an after school science club providing opportunities for students to work on their science fair projects and pursuit other science interests. Students are provided scoring rubrics and their progress is creatively assessed through KWL worksheets, concept maps, surveys, oral one on one and classroom discussions and writing samples. The year culminated with a series of hands on lessons at the nearby beach, where students demonstrated their mastery of skills through practical application. Benefits to the graduate student include improved communication of current science research to a diverse audience, a better understanding of the

Inquiry is a teaching strategy in which student work mirrors authentic scientific research: students have ownership over their learning path, and learning scientific concepts (e.g., properties of light, motion in a gravitational field) is intertwined with learning scientific practices (e.g., asking questions, planning an investigation, constructing explanations). I will describe inquiry and education research showing its effectiveness; and I will present inquiry-based astronomy curricula and assessment strategies we have designed for undergraduate and graduate courses in Nigeria and Canada: an activity on the cosmic distance ladder (part of a short course in Abuja); a course on order-of-magnitude astronomy problem solving (Toronto); and new education research from the Carl Wieman Science Education Initiative at the University of British Columbia (where I am a new postdoc).

The field of environmental health requires the knowledge of many facts and terms, and it also requires mastery of an array of concepts that can be difficult for many students to thoroughly comprehend. Guided-inquiry learning is a process by which students "discover" basic concepts through active investigation. In this article, the authors describe several guided-inquiry learning modules used in their undergraduate environmental health program and their experience in using them. Some modules are used in professional courses while others are used in a general education course. Overall, the authors experienced increased student engagement and interest with guided-inquiry learning. Students are able to comprehend some abstract concepts more quickly and seem to retain the concepts longer.

Students identified as gifted come from varying socio-economic strata and nationalities with a range of talents and temperaments comprising a diverse community. They may experience stress for a variety of reasons. Although a certain amount of stress can enhance the learning process, too much stress can impede learning, especially memory. Strategies have been offered for relieving stress, yet the benefits of physical activities as stress reducers for the gifted have frequently been overlooked. The purpose of this study was to investigate the relationship among aerobic activity, stress, and memory ability in students in an elementary school gifted program. An exceptional aspect of this research was that the students were an integral part of their own study. As co-researchers they had a vested interest in what they were doing, enhancing the significance of the experience and heightening learning. This action research project conducted in a mid-western school district with fourth and fifth grade students examined the impact of aerobic movement on physical indicators of stress and memory. The study lasted twelve weeks with data collected on physical indicators of stress, memory test scores, parent observations, interviews with students, a parent focus group session, observational data, student comments, and investigator/teacher journal. By infusing regular exercise into curricula, stress levels in students identified as gifted were examined. Students' scores on declarative memory tasks conducted with and without an accompanying aerobic activity were documented. Students learned of the delicate relationship between stress and memory as they studied the physiology of the brain. Twenty-four hour retention rates of declarative memory items were higher when a 20-minute aerobic activity intervention preceded the memory activity. Perceived stress levels were lowered for 14 of the 16 co-researchers. Students indicated a positive attitude toward physical activity and its

Hands-On Optics (HOO) is a collaborative four-year program to create and sustain a unique, national, informal science education program to excite students about science by actively engaging them in optics activities. The standards based activities and demonstrations have been successfully used in a variety of settings including formal classrooms, after school clubs, and science centers. One of the themes for the International Year of Astronomy (IYA) is "Looking Through a Telescope". We intend to use HOO activities in conjunction with the IYA to reinforce this important area. In this workshop, participants completed a series of activities involving refraction, lenses, telescopes, and ultraviolet light and took home a kit containing all the materials required to do the activities with a small group of students. Participants explored the basic properties of positive lenses to create images through the use of hands-on activities, exciting experiments, and educator-lead demonstrations, culminating with the building of a small refracting telescope. Several prototype telescopes were examined in the workshop for use in the International Year of Astronomy.

Inquiry teaching often rests upon the assumption that through the use of questioning and response strategies, teachers can stimulate students to actively construct knowledge. Based on this hypothesis, middle-school science lessons were observed and questioning and response strategies were identified that are related to inquiry-based instruction. Twenty-four science lessons were observed, videotaped, and ranked by inquiry characteristics other than questioning strategy. The video and audio portions of the recordings were analyzed to determine the student and teacher's questioning and response strategies in each classroom. These strategies were then compared to teaching style, along a continuum from traditional to inquiry, to identify questioning and response strategies that stimulate students to ask questions, solve problems, analyze evidence, consider alternative explanations, and other similar inquiry behaviors. The analyses indicated several questioning strategies of teachers that are related to inquiry teaching and learning and might be used as indicators of inquiry teaching in middle school science lessons. These include the number of content-related questions asked by teachers, the number of divergent questions asked by teachers, the number of times teachers probe for the intended response, the number of times teachers answer students' questions, and the number questions per concept asked by teachers. Perhaps more important was the observation that even after several decades of emphasizing the importance of inquiry methods in science education, neither students nor teachers participating in this study are asking higher-level cognitive questions deemed to be an important facet in the effective teaching and learning of science.

Hands-On Optics (HOO) is a collaborative four-year program to create and sustain a unique, national, informal science education program to excite students about science by actively engaging them in optics activities. It will reach underrepresented middle school students in after-school programs and at hands-on science centers nationwide. Project partners with NOAO are SPIE-The International Society for Optical Engineering, the Optical Society of America (OSA), and the Mathematics, Engineering, Science Achievement Program (MESA) of California. This program builds on the 2001 National Science Foundation planning grant (number ESI-0136024), Optics Education - A Blueprint for the 21st Century, undertaken to address the disconnect between the ubiquity of optics in everyday life and the noticeable absence of optics education in K-12 curricula and in informal science education. NOAO - with expertise in teaching optics, developing optics kits, and in science-educator partnerships is designing the HOO instructional materials by adapting well-tested formal education activities on light, color, and optical technology for the informal setting. These hands-on, high-interest, standards-connected activities and materials serve as the basis for 6, three-hour-long optics activity modules that will be used in informal education programs at 23 HOO host sites. NOAO also will train the educators, parents, and optics professionals who will work in teams to lead the HOO activities. A key component of the project will be the optics professionals from the two optical societies who currently are engaged in outreach activities and programs. Optics professionals will serve as resource agents teamed with science center and MESA educators, a model very successfully used by the Astronomical Society of the Pacific's Project ASTRO. The six modules and associated challenges and contests address reflection from one or many mirrors, image formation, colors and polarization, ultraviolet and infrared

Transitioning to a new discipline can be challenging because of the need to quickly assimilate new skills and knowledge that others brought up in the field took years to develop. While reading and taking classes help to add knowledge, hands-on experience is key to developing your new skill set. Fieldwork is one obvious way to gain experience. Fieldwork provides intimate knowledge of your new found discipline, which is one component of your skill set. However, fieldwork is normally for a short period of time and very focused, which does not quickly provide the second component of your skill set, that is, insight into how your discipline fits in the big picture of solving problems. Academic workshops and internships can help provide the additional experience to bring any young researcher into this higher level of understanding. As a specific example, I'll talk about a summer workshop I recently attended called CIDER (Cooperative Institute for Dynamic Earth Research), which is open for students to apply for every year. This workshop provided the opportunity to learn a working knowledge of other disciplines in geology, and helped to expand my view of geophysics' place in solving real problems. The workshop is a month long, the first two weeks of which were lectures and tutorials of every discipline represented. The second two weeks consisted of new research on projects that were proposed by the attendees. The attendees select which of those projects to participate in, and join a team to work vigorously for two weeks. Teams may continue work after the CIDER workshop for presentations at AGU (as in my case) and has potential for publication later. Why this workshop succeeds in advancing young researchers' understanding is that different disciplines work side by side on their research project. Students need to be made aware of this workshop, and other workshops and internships like it, to provide this added hands-on experience.

Intracellular and extracellular communication is conducted through an intricate and interwoven network of signal transduction pathways. The mechanisms for how cells speak with one another are of significant biological importance to both basic and industrial scientists from a number of different disciplines. We have therefore developed and implemented a new laboratory-intensive course that teaches students the theory and techniques used to study cell signaling pathways. Students learn these methodologies as they conduct a hypothesis-driven research project where they elucidate the mechanism of breast cancer cell death caused by a cancer chemotherapeutic agent. While each lab experiment can be conducted independently, the findings build upon one another to form the beginnings of a signaling pathway. In the lecture component of the course, students investigate different signaling pathways and the methods employed to study them. In addition, students actively participate in journal article discussions where they assess the primary scientific literature. We evaluated the course over two semesters and found that in both semesters learning outcomes were met by both undergraduate and graduate students. The evaluation of the course was based on a number of instructor assessments of student work, including lab reports, experimental results, journal article discussions, and a final cumulative exam. Furthermore, students' self-assessments revealed gains in perceived confidence in both conceptual knowledge and technical skills

Science education reforms worldwide call on teachers to engage students in investigative approaches to instruction, like inquiry. Studies of teacher self-reported enactment indicate that inquiry is used frequently in the classroom, suggesting a high level of proficiency with inquiry that would be amenable to inquiry reform. However, it is unclear whether the high frequency of self-report is based on sound knowledge inquiry. In the absence of sound knowledge, high rates of self-reported enactment would be suspect. We conducted a study to measure teachers' knowledge of inquiry as it related to the known, high frequency of reported enactment. We developed a multidimensional survey instrument using US reform documents and administered it to 149 K-12 teachers at a national science teachers' conference. The majority of the teachers surveyed did not report inquiry enactment based on well-structured knowledge of inquiry. Interviews with participants showed how teachers could readily map non-inquiry activities onto inquiry statements taken directly from reform documents. From these results we argue that teachers often believed they were enacting inquiry, when likely they were not. We further reason that teachers may struggle to interpret and enact inquiry-related requirements of science education reform and will need support distinguishing inquiry from non-inquiry practices.

The Graduate K-12 (GK12) program has been developed by NSF to support the national effort to advance scientific knowledge through educational partnerships. This paper highlights research conducted during the 2006-2007 school year with the Texas A&M University GK12 project. Two elementary schools with very high numbers of at risk students - those who are poor, speak English as their second language, and have a history of failing state-mandated tests were identified to be the field site for the GK12 project. In these two, high-minority (97% and 40% African American and Hispanic) schools, 80% and 56% of the children have been identified by the state as at risk; 94% and 52% are classified as economically disadvantaged; and 46% and 2% are limited English proficient, respectively. In the past year, 30% and 73% of fifth grade students in these schools passed the science portion of the Texas Assessment of Knowledge and Skills (TAKS) test. Data collected during a three- week period where GK12 fellows taught the fifth graders Earth science-related topics is presented. During the implementation, students were engaged in technology-, inquiry-, and game-based activities. Students were divided into low-, medium-, and high-abilities in one school, and regular and bilingual groups in the other. Pre- post open-ended multiple choice tests indicated that all but the low performing students' conceptual understanding (CU) significantly (p < 0.05) improved during the IT activity. The low and high student groups' CU significantly improved during the inquiry activity, and the high and bilingual students' CU significantly improved for the game activities. Classroom observation assessments showed that there was a significant (p < 0.10) positive (0.347) correlation between on-task behavior and CU. Significant differences between student groups' CU and on-task behavior indicated that technology-based activities showed greatest differences between the low- ability learners and the other

We have developed a set of laboratories and hands on activities to accompany a new two-semester interdisciplinary physics course that has been successfully implemented as the required physics course for premeds at the University of Maryland. The laboratories include significant content on physics relevant to cellular scales, from chemical interactions to random motion and charge screening in fluids. We also introduce the students to research-grade equipment and modern physics analysis tools in contexts relevant to biology, while maintaining the pedagogically valuable open-ended laboratory structure of reformed laboratories.

In this paper, the effect of introducing visible spectrometry concepts through hands-on laboratory work upon student learning within four vocational programs are discussed. All together, 118 students, average 18.6 years old, participated in the study. The results showed no correlation between students' motivational components (intrinsic, regulated, and controlled), chemistry self-concept and their achievement on an experiential knowledge test and knowledge gained from this hands-on approach. Statistically significant differences were found for academic achievement among students in a biotechnology technical program (School 1), food processing program (School 2), laboratory biomedicine program (School 3), and a biotechnology general program (School 4). Differences in academic achievement are further reflected in students' perception of particular knowledge gained through their hands-on experiences and in their expressed attitude toward different didactical characteristics. All students, regardless of their study program, highly evaluated the relaxed atmosphere that contributed to their self-confidence in completing their laboratory activities. PMID:23841355

Science education research has recommended cooperative inquiry based science in the primary science context for more than two decades but after more than 20 years, student achievement in science has not substantially improved. This study, through direct observation and analysis, investigated content-related student interactions in an authentic inquiry based primary science class setting. Thirty-one upper primary students were videotaped working in cooperative inquiry based science activities. Cooperative talk and negotiation of the science content was analysed to identify any high-level group interactions. The data show that while all groups have incidences of high-level content-related group interactions, the frequency and duration of these interactions were limited. No specific pattern of preceding events was identified and no episodes of high-level content-related group interactions were immediately preceded by the teacher's interactions with the groups. This in situ study demonstrated that even without any kind of scaffolding, specific skills in knowing how to implement cooperative inquiry based science, high-level content-related group interactions did occur very briefly. Support for teachers to develop their knowledge and skills in facilitating cooperative inquiry based science learning is warranted to ensure that high-level content-related group interactions and the associated conceptual learning are not left to chance in science classrooms.

This presentation provides an overview of a hands-on modeling tool developed for students in civil engineering and earth science disciplines to help them learn the fundamentals of hydrologic processes, model calibration, sensitivity analysis, uncertainty assessment, and practice conceptual thinking in solving engineering problems. The toolbox includes two simplified hydrologic models, namely HBV-EDU and HBV-Ensemble, designed as a complement to theoretical hydrology lectures. The models provide an interdisciplinary application-oriented learning environment that introduces the hydrologic phenomena through the use of a simplified conceptual hydrologic model. The toolbox can be used for in-class lab practices and homework assignments, and assessment of students' understanding of hydrological processes. Using this modeling toolbox, students can gain more insights into how hydrological processes (e.g., precipitation, snowmelt and snow accumulation, soil moisture, evapotranspiration and runoff generation) are interconnected. The educational toolbox includes a MATLAB Graphical User Interface (GUI) and an ensemble simulation scheme that can be used for teaching more advanced topics including uncertainty analysis, and ensemble simulation. Both models have been administered in a class for both in-class instruction and a final project, and students submitted their feedback about the toolbox. The results indicate that this educational software had a positive impact on students understanding and knowledge of hydrology.
Version 00 The U.S. Nuclear Regulatory Commission (NRC) has developed a powerful personal computer (PC) software application for performing probabilistic risk assessments (PRAs), called Systems Analysis Programs for Hands-on Integrated Reliability Evaluations (SAPHIRE) Version 8. Using SAPHIRE 8 on a PC, an analyst can perform a PRA for any complex system, facility, or process. Regarding nuclear power plants, SAPHIRE can be used to model a plant's response to initiating events, quantify associated core damage frequencies,more » and identify important contributors to core damage (Level 1 PRA). It can also be used to evaluate containment failure and release models for severe accident conditions, given that core damage has occurred (Level 2 PRA). It can be used for a PRA assuming that the reactor is at full power, at low power, or at shutdown conditions. Furthermore, it can be used to analyze both internal and external initiating events, and it has special features for transforming models built for internal event analysis to models for external event analysis. It can also be used in a limited manner to quantify risk for release consequences to both the public and the environment (Level 3 PRA). For all of these models, SAPHIRE can evaluate the uncertainty inherent in the probabilistic models. SAPHIRE has evolved with advances in computer technology.« less

The major failures reported in the Bristol inquiry have been highlighted in most hospital inquiry reports over the past 30 years. The tendency to victimise the whistleblower has characterised virtually all inquiries. Inadequate leadership, isolation, system failures, poor communication and disempowerment of staff and service users are the common themes. While organisational reform is essential, the real challenge is to change behaviour. And this depends on the example of senior staff.

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 textbooks is important contribution of the entropy in driving fundamental biological processes towards equilibrium. From diffusion to cell-membrane formation, to electrostatic binding in protein folding, to the functioning of nerve cells, entropic effects often act to counterbalance deterministic forces such as electrostatic attraction and in so doing, allow for effective molecular signaling. A small group of biology, biophysics and computer science faculty have worked together for the past five years to develop curricular modules (based on SCALEUP pedagogy). This has enabled students to create models of stochastic and deterministic processes. Our students are first-year engineering and science students in the calculus-based physics course and they are not expected to know biology beyond the high-school level. In our class, they learn to reduce complex biological processes and structures in order model them mathematically to account for both deterministic and probabilistic processes. The students test these models in simulations and in laboratory experiments that are biologically relevant such as diffusion, ionic transport, and ligand-receptor binding. Moreover, the students confront random forces and traditional forces in problems, simulations, and in laboratory exploration throughout the year-long course as they move from traditional kinematics through thermodynamics to electrostatic interactions. This talk will present a number of these exercises, with particular focus on the hands-on experiments done by the students, and will give examples of the tangible material that our students work with throughout the two-semester sequence of their course on introductory
Student achievement in the Twenty First Century demands a new rigor in student science knowledge, since advances in science and technology require students to think and act like scientists. As a result, students must acquire proficient levels of knowledge and skills to support a knowledge base that is expanding exponentially with new scientific advances. This study examined the effects of hands-on-science instruction on the science achievement of middle school students. More specifically, this study was concerned with the influence of hands-on science instruction versus traditional science instruction on the science test scores of middle school students. The subjects in this study were one hundred and twenty sixth-grade students in six classes. Instruction involved lecture/discussion and hands-on activities carried out for a three week period. Specifically, the study ascertained the influence of the variables gender, ethnicity, and socioeconomic status on the science test scores of middle school students. Additionally, this study assessed the effect of the variables gender, ethnicity, and socioeconomic status on the attitudes of sixth grade students toward science. The two instruments used to collect data for this study were the Prentice Hall unit ecosystem test and the Scientific Work Experience Programs for Teachers Study (SWEPT) student's attitude survey. Moreover, the data for the study was treated using the One-Way Analysis of Covariance and the One-Way Analysis of Variance. The following findings were made based on the results: (1) A statistically significant difference existed in the science performance of middle school students exposed to hands-on science instruction. These students had significantly higher scores than the science performance of middle school students exposed to traditional instruction. (2) A statistically significant difference did not exist between the science scores of male and female middle school students. (3) A statistically

Incomprehension and denial of the theory of evolution among high school students has been observed to also occur when teachers are not equipped to deliver a compelling case also for human evolution based on fossil evidence. This paper assesses the outcomes of a novel inquiry-based paleoanthropology lab teaching human evolution to high-school students. The inquiry-based Be a Paleoanthropologist for a Day lab placed a dozen hominin skulls into the hands of high-school students. Upon measuring three variables of human evolution, students explain what they have observed and discuss findings. In the 2013/14 school year, 11 biology classes in 7 schools in the Greater New Orleans area participated in this lab. The interviewed teacher cohort unanimously agreed that the lab featuring hominin skull replicas and stimulating student inquiry was a pedagogically excellent method of delivering the subject of human evolution. First, the lab’s learning path of transforming facts to data, information to knowledge, and knowledge to acceptance empowered students to themselves execute part of the science that underpins our understanding of deep time hominin evolution. Second, although challenging, the hands-on format of the lab was accessible to high-school students, most of whom were readily able to engage the lab’s scientific process. Third, the lab’s exciting and compelling pedagogy unlocked higher order thinking skills, effectively activating the cognitive, psychomotor and affected learning domains as defined in Bloom’s taxonomy. Lastly, the lab afforded students a formative experience with a high degree of retention and epistemic depth. Further study is warranted to gauge the degree of these effects. PMID:27513927

Social digital gaming is an explosive phenomenon where youth and adults are engaged in inquiry for the sake of fun. The complexity of learning evidenced in social digital games is attracting the attention of educators. Martian Boneyards is a proof-of-concept game designed to study how a community of voluntary gamers can be enticed to engage in sustained, high-quality scientific inquiry. Science educators and game designers worked together to create an educational game with the polish and intrigue of a professional-level game, striving to attract a new audience to scientific inquiry. Martian Boneyards took place in the high-definition, massively multiplayer online environment, Blue Mars, where players spent an average of 30 hours in the game over the 4-month implementation period, with some exceeding 200 hours. Most of the players' time was spent in scientific inquiry activities and about 30% of the players' in-game interactions were in the analysis and theory-building phases of inquiry. Female players conducted most of the inquiry, in particular analysis and theory building. The quality of scientific inquiry processes, which included extensive information gathering by players, and the resulting content were judged to be very good by a team of independent scientists. This research suggests that a compelling storyline, a highly aesthetic environment, and the emergent social bonds among players and between players and the characters played by designers were all responsible for sustaining high quality inquiry among gamers in this free-choice experience. The gaming environment developed for Martian Boneyards is seen as an evolving ecosystem with interactions among design, players' activity, and players' progress.

Enactment of scientific inquiry in classroom has attracted a great attention of science educators around the world. In this study, we examined two competent teachers' (one Grade 9 chemistry teacher and one Grade 4 science teacher) enactment of scientific inquiry in selected teaching units to reveal the characteristics of enacted inquiry at different grade levels by analyzing lesson sequence videos. The coding schemes for enacted inquiry consist of ontological properties and instructional practices. Pre-topic and post-topic teacher interviews and the two teachers' responses to a questionnaire were adopted to identify the factors influencing teacher's enactment. The results indicate that the two case teachers' enactment involved a range of inquiry activities. The enacted inquiry at fourth-grade level covered all the inquiry elements, tending to engage students in the whole procedure of inquiry. The ninth-grade chemistry class placed emphasis on the elements "making plans" to solve problems in authentic context. Important factors influencing the enactment include teacher's understanding about scientific inquiry, textbooks, assessment, students and resource. Implications for inquiry enactment and instruction improvement have been provided.

This study investigated scaffolding elementary school students' formulation of explanations through an 8-week biodiversity curriculum. Authentic inquiry situations in the curriculum provided opportunities for students to conduct elements of scientists' practices in hands-on investigations driven by the students' interests. Three support features-modeled explanations, direct content prompts, and sentence starters-were designed to help students focus on salient features of the inquiry situations. These three support features were placed differently in two treatments. In the consistent support treatment, three support features were present throughout eleven authentic inquiry situations. In the fading support treatment, three support features were gradually withdrawn over the same inquiry situations. The manipulation of the fading dimension of the scaffolding concept was based on the idea that students can learn more effectively when they take more responsibility to complete the learning task as they gain knowledge and experience. Forty-eight students in two 5th/6th combined classes participated. This study was quasi-experimental with two treatment variations. Based on students' prior knowledge and explanation ability, block strategies were used to assign students into the two treatments. Data sources included a multiple-choice test and an open-ended test administered before and after the treatments. Students' written explanations in the eleven inquiry situations were collected. Eighteen students were interviewed after the treatments. Results demonstrate that both groups improved on the multiple-choice and open-ended tests. While these two tests were not sensitive to the treatment differences, students' explanations were a much better indicator of the treatment effects. The consistent support group included fewer valid warrants in explanations before the treatments but gradually outperformed the fading support group as certain support features were withdrawn in the

The need for improving the representation of cloud processes in climate models has been one of the most important limitations of the reliability of climate-change simulations. Now in its fourth year, the National Science Foundation-funded Center for Multi-scale Modeling of Atmospheric Processes (CMMAP) at Colorado State University (CSU) is addressing this problem through a revolutionary new approach to representing cloud processes on their native scales, including the cloud-scale interaction processes that are active in cloud systems. CMMAP has set ambitious education and human-resource goals to share basic information about the atmosphere, clouds, weather, climate, and modeling with diverse K-12 and public audiences. This is accomplished through collaborations in resource development and dissemination between CMMAP scientists, CSU’s Little Shop of Physics (LSOP) program, and the Windows to the Universe (W2U) program at University Corporation for Atmospheric Research (UCAR). Little Shop of Physics develops new hands on science activities demonstrating basic science concepts fundamental to understanding atmospheric characteristics, weather, and climate. Videos capture demonstrations of children completing these activities which are broadcast to school districts and public television programs. CMMAP and LSOP educators and scientists partner in teaching a summer professional development workshops for teachers at CSU with a semester's worth of college-level content on the basic physics of the atmosphere, weather, climate, climate modeling, and climate change, as well as dozens of LSOP inquiry-based activities suitable for use in classrooms. The W2U project complements these efforts by developing and broadly disseminating new CMMAP-related online content pages, animations, interactives, image galleries, scientists’ biographies, and LSOP videos to K-12 and public audiences. Reaching nearly 20 million users annually, W2U is highly valued as a curriculum enhancement
The purpose of this phenomenographic study was to: (a) understand how beginning science teachers recruited from various science disciplines and prepared in an Alternative Teacher Certification Program (ATCP) implemented inquiry during their initial years of teaching; (b) describe constraints and needs that these beginning science teachers perceived in implementing inquiry-based science instruction; and (c) understand the relation between what they learned in their ATCP and their practice of teaching science through inquiry. The participants of this study consisted of four ATCP teachers who are in their beginning years of teaching. Semi-structured interviews, classroom observation, field notes, and artifacts used as source of data collection. The beginning science teachers in this study held incomplete views of inquiry. These views of inquiry did not reflect inquiry as described in NRC (2000)---essential features of inquiry,---nor did they reflect views of faculty members involved in teaching science methods courses. Although the participants described themselves as reform-oriented, there were inconsistencies between their views and practices. Their practice of inquiry did not reflect inquiry either as outlined by essential features of inquiry (NRC, 2000) or inquiry as modeled in activities used in their ATCP. The research participants' perceived constraints and needs in their implementation of inquiry-based activities. Their perceived constraints included logistical and student constraints and school culture. The perceived needs included classroom management, pedagogical skills, practical knowledge, discipline, successful grade-specific models of inquiry, and access to a strong support system. Prior professional work experience, models and activities used in the ATCP, and benefits of inquiry to student learning were the declared factors that facilitated the research participants' practice of inquiry-based teaching.

Decades of discussion and debate about how science is most effectively taught and learned have resulted in a number of similar but competing inquiry models. These aim to develop students learning of science through approaches which reflect the authenticity of science as practiced by professional scientists while being practical and manageable within the school context. This paper offers a collection of our current reflections and suggestions concerning inquiry and its place in science education. We suggest that many of the current models of inquiry are too limited in their vision concerning themselves, almost exclusively, with producing a scaffold which reduces the complex process of inquiry into an algorithmic approach based around a sequence of relatively simple steps. We argue that this restricts students' experience of authentic inquiry to make classroom management and assessment procedures easier. We then speculate that a more integrated approach is required through an alternative inquiry model that depends on three dimensions (conceptual, procedural and personal) and we propose that it will be more likely to promote effective learning and a willingness to engage in inquiry across all facets of a students' school career and beyond.

With increased concern over the environment, all Ontario students now study soils, energy conservation, water systems, and climate change & the greenhouse effect in Grades 3, 5, 7, 8 and 10. Unfortunately, many prospective teachers at the elementary and intermediate levels come to teacher education programs with little or no formal science education beyond their own experiences as students in the K-12 system. We devised a series of concept tests (some binary choice, some multiple choice) designed to assess teacher candidates' conceptual understandings of soils, energy, water systems, and climate change and the greenhouse effect - the very content they are expected to teach their future students in the school system. We administered a pre-test to our students at two institutions to establish a baseline of their understanding. Then, we specifically devoted class time to exploring each of these themes in our science curriculum methods courses in order using research-based principles of teaching devoted to promoting conceptual change through the use of hands-on, inquiry approaches in science. After a few months had passed, we again administered the same tests to teacher candidates to measure candidates' conceptual gain. Some teacher candidates also participated in follow-up focus group interviews so that they could have the opportunity to articulate their understandings of concepts in environmental science using their own words. In this poster we will report on data collected for this project over the past two academic years. We have reached two broad conclusions. First, teacher candidates know a considerable amount about the four environmental topics that were selected, despite the fact that most participants in the research did not have post-secondary training in science. For example, participants tended to know that planting different crops on the soil in different years helps to maintain fertile soils and that warmer oceans will cause an increase in the severity of

The purpose of this study was to examine the role professional development takes in fostering change in the pedagogical practices of K--5 classroom teachers, specifically in teaching science through inquiry. Michael Fullan's three elements essential for change: curriculum, instruction, and philosophy, were used as the lens through which to observe and analyze the impact of an intervention for changing teaching practices in K--5 classrooms. The intervention that assisted in creating an environment for change in behaviors was a morphed version of the Exploratorium's Institute for Inquiry, the ASSET Institute for Inquiry, in Pittsburgh, Pennsylvania. During a three year period 208 teachers attended the five day Institute. It modeled the pedagogy, philosophy and related curriculum strategies indigenous to teaching science through inquiry. Each teacher was sent a questionnaire. The questionnaire was a compilation of Horizon Research, National Science Education Standards, and the National Science Education Inquiry Standard. The analysis of the statistical relationships between the Institute and change in the use of curriculum, instruction, or beliefs in action was done. The results indicate a statistically significant relationship between the Institute for Inquiry and change in teaching practices. There was an increase in the use and implementation of hands-on inquiry-based curricula: STC, FOSS, and INSIGHTS. There was an increase in those instructional strategies and classroom practices supportive of science through inquiry. There was a statistical relationship between the intervention and the NSES indicators of inquiry in practice. Further research was done with regard to teaching experience (i.e., number of years teaching), time interval between completion of the intervention and implementation of the philosophy and strategies indigenous to inquiry, and the relationship a resource teacher (e.g., teacher teaching teacher) develops with classroom teachers and the

Two seemingly complementary trends stand out currently in school science education in the United States: one is the increased emphasis on inquiry activities in classrooms, and the other is the high level of attention given to student understanding of the nature of science. This essay looks at the range of activities that fall within the first trend, noting, in particular, the growing popularity of inquiry activities that engage students in engineering-type tasks. The potential for public disengagement from science and technology issues is described as a result of the continued juxtaposition of these sorts of inquiry activities with our current, idealized portrayals of the nature of science - the emphasis of the second trend. Drawing on Dewey's instrumental theory of knowledge, an alternative way of thinking about science is offered that would not only provide for a more authentic understanding of science, but also invite much needed public participation in the broad governance of science in modern-day democratic societies.

This exercise sets up a collaborative activity that challenges students to develop a chromatographic solvent with the appropriate polarity to separate leaf chlorophyll and anthocyanin pigments by TLC. The suggested activity has been tested with both high-school advanced-chemistry students and with undergraduate students in an introductory biochemistry class. It includes a demonstration introducing the basic principles of partitioning and differential distribution based on solubility. For the student activity, the materials to be used are leaves of the variegated Coleus plant, plastic-backed silica TLC plates, 2-propanol, acetone, and methanol. Students may work collaboratively within a set of boundary parameters to optimize the chromatographic solvent through a series of rapid iterations of chromatography. Students can also use these chromatography systems to carry out independent projects.

The purpose of this study was to determine if there was a difference in the perception of scientific inquiry between experts and practitioners, and, if a difference was shown to exist, to analyze those perceptions in order to better understand the extent of that difference or gap. A disconnect was found between how experts and practitioners perceived scientific inquiry. The practitioners differed from both the experts and the literature in three key areas. First, although the teachers indicated that students would be manipulating materials, there was no direct reference to this manipulation actually being performed for the purpose of investigating. Second, the practitioners implied active physical engagement with materials, but they did not tie this to active mental engagement or direct involvement in their own learning. Third, teachers omitted their role in laying the foundation for inquiry. Though classroom teachers lacked a complete understanding of true inquiry and its place in the K-12 classroom, most of them actually believed they were practicing the art of teaching via inquiry. Additionally, two other points of interest arose. First, an examination of the national standards for a number of curricular areas established that the process skills of scientific inquiry are mirrored in those standards, implying that inquiry is not limited to the sciences. Second, a definition of inquiry was formulated based upon interviews with experts in the field. Although the literature and the experts were in unison in their definition, there was a disparity between the accepted definition and that provided by the teachers. The struggle for a comprehensive understanding of inquiry continues to this day. It might very well be that the concept still remains elusive partly because the teacher behaviors associated with it run counter to more traditional methods of instruction...methods that most teachers have experienced throughout their own educational careers. The most pervasive

Created in 1994 in the wake of the closure of the Space Camp of Patrick Baudry in Cannes, Classes Azur Astro Espace (AAE) provide a world's unique combination of space and astronomy courses, as given by active and retired professionals of two of the best space and astronomical facilities extant: Alcatel Space in Cannes and Observatoire de la Côte d'Azur (OCA) in Nice, Grasse and Caussols. Fifteen space modules, of 30 to 60 minutes each, have been established, giving simple and clear explanations on launchers, satellites, their applications, their development, together with an historical background. Basic experiments are included, such as an unique small catapult to explain gravity, or more classical water rockets. The basic AAE sojourn extends over 3 days: one day for space (including a visit of Alcatel Space, the biggest satellite manufacturer outside the US and Russia), one day for astronomy (including a visit of the biggest observatory in Europe) and one day à-la-carte (Côte d'Azur offers much, such as the Oceanographic Museum in Monaco). More and more groups are adding a fourth day, with a visit to the nice old village of Perinaldo in Italy, where famous astronomer Cassini was born. Lycée de Cachan, near Paris, even takes 12-day sojourns every year. The public has been extremely wide, from age 5 to 70, from students to enthusiasts. Coming initially all over from France, participants now include since 2001 German and Italian pupils and teachers. In 2001 also, ESA came in the shape of a Space Camp. ISU's Master of Space Studies participates to a shortened version of AAE every even-year. Up to the end of 2001, 62 classes with 2,025 participants from 20 countries had thus come to enjoy space education on Côte d'Azur. Such success is due in no small part to the very attractive price and flexibility of these activities, notably thanks to the support of ESA, CNES, Rectorat d'Académie de Nice, Conseil Général des Alpes-Maritimes, Ville de Cannes, AAAF, TDF

Older adults’ preferences to remain independent in their own homes along with the high costs of nursing home care have motivated the development of Ambient Assisted Living (AAL) technologies which aim at improving the safety, health conditions and wellness of the elderly. This paper reports hands-on experiences in designing, implementing and operating UbiCare, an AAL based prototype system for elderly home care monitoring. The monitoring is based on the recording of environmental parameters like temperature and light intensity as well as micro-level incidents which allows one to infer daily activities like moving, sitting, sleeping, usage of electrical appliances and plumbing components. The prototype is built upon inexpensive, off-the-shelf hardware (e.g., various sensors, Arduino microcontrollers, ZigBee-compatible wireless communication modules) and license-free software, thereby ensuring low system deployment costs. The network comprises nodes placed in a house’s main rooms or mounted on furniture, one wearable node, one actuator node and a centralized processing element (coordinator). Upon detecting significant deviations from the ordinary activity patterns of individuals and/or sudden falls, the system issues automated alarms which may be forwarded to authorized caregivers via a variety of communication channels. Furthermore, measured environmental parameters and activity incidents may be monitored through standard web interfaces. PMID:26094631

In this work, various alternative teaching methods and activities for chemical education are developed, presented, and evaluated. In the first study, an original hands-on activity using LEGO® blocks to model ionic chemical formulas is presented together with quantitative and qualitative data regarding its educational effectiveness. Students explore cation to anion ratios using LEGO® blocks to represent trivalent, divalent and monovalent cations and anions. High school chemistry students who participated in the LEGO® lab showed significantly higher post-test scores than other students. The second study grows out of the creation of a computational lab module that is shown to significantly increase student learning in the subject of molecular orbital theory in first semester college General Chemistry. The third and final study presented is a course redesign project for college CHEM 1100, Preparation for General Chemistry. In this project the classroom is “flipped”. Students watch video lectures at home, and spend class time working with peers and the instructor on problem solving activities. The results presented here are one of the first quantitative studies showing the effectiveness of “flipping the classroom”. Students who were taught using the Reverse-Instruction (RI) method had significantly higher success in both the Preparation for General Chemistry course and traditionally taught General Chemistry I the following semester.

In the Budding Science and Literacy project, we explored how working with an integrated inquiry-based science and literacy approach may challenge and support the teaching and learning of science at the classroom level. By studying the inter-relationship between multiple learning modalities and phases of inquiry, we wished to illuminate possible dynamics between science inquiry and literacy in an integrated science approach. Six teachers and their students were recruited from a professional development course for the current classroom study. The teachers were to try out the Budding Science teaching model. This paper presents an overall video analysis of our material demonstrating variations and patterns of inquiry-based science and literacy activities. Our analysis revealed that multiple learning modalities (read it, write it, do it, and talk it) are used in the integrated approach; oral activities dominate. The inquiry phases shifted throughout the students' investigations, but the consolidating phases of discussion and communication were given less space. The data phase of inquiry seems essential as a driving force for engaging in science learning in consolidating situations. The multiple learning modalities were integrated in all inquiry phases, but to a greater extent in preparation and data. Our results indicate that literacy activities embedded in science inquiry provide support for teaching and learning science; however, the greatest challenge for teachers is to find the time and courage to exploit the discussion and communication phases to consolidate the students' conceptual learning.

Abstract Scientific inquiry represents a multifaceted approach to explore and understand the natural world. Training students in the principles of scientific inquiry can help promote the scientific learning process as well as help students enhance their understanding of scientific research. Here, we report on the development and implementation of a learning module that introduces astrobiology students to the concepts of creative and scientific inquiry, as well as provide practical exercises to build critical thinking skills. The module contained three distinct components: (1) a creative inquiry activity designed to introduce concepts regarding the role of creativity in scientific inquiry; (2) guidelines to help astrobiology students formulate and self-assess questions regarding various scientific content and imagery; and (3) a practical exercise where students were allowed to watch a scientific presentation and practice their analytical skills. Pre- and post-course surveys were used to assess the students' perceptions regarding creative and scientific inquiry and whether this activity impacted their understanding of the scientific process. Survey results indicate that the exercise helped improve students' science skills by promoting awareness regarding the role of creativity in scientific inquiry and building their confidence in formulating and assessing scientific questions. Together, the module and survey results confirm the need to include such inquiry-based activities into the higher education classroom, thereby helping students hone their critical thinking and question asking skill set and facilitating their professional development in astrobiology.

Elementary school students' understanding of both science content and processes are enhanced by the higher level thinking associated with inquiry-based science investigations. Informal science setting personnel, elementary school teachers, and curriculum specialists charged with designing inquiry-based investigations would be well served by an understanding of the varying influence of certain present factors upon the students' willingness and ability to delve into such higher level inquiries. This study examined young children's use of inquiry-based materials and factors which may influence the level of inquiry they engaged in during informal science activities. An informal science setting was selected as the context for the examination of student inquiry behaviors because of the rich inquiry-based environment present at the site and the benefits previously noted in the research regarding the impact of informal science settings upon the construction of knowledge in science. The study revealed several patterns of behavior among children when they are engaged in inquiry-based activities at informal science exhibits. These repeated behaviors varied in the children's apparent purposeful use of the materials at the exhibits. These levels of inquiry behavior were taxonomically defined as high/medium/low within this study utilizing a researcher-developed tool. Furthermore, in this study adult interventions, questions, or prompting were found to impact the level of inquiry engaged in by the children. This study revealed that higher levels of inquiry were preceded by task directed and physical feature prompts. Moreover, the levels of inquiry behaviors were haltered, even lowered, when preceded by a prompt that focused on a science content or concept question. Results of this study have implications for the enhancement of inquiry-based science activities in elementary schools as well as in informal science settings. These findings have significance for all science educators
