Multiple case studies of STEM teachers' orientations to science teaching through engineering design

NASA Astrophysics Data System (ADS)

Rupp, Madeline

The following master's thesis is composed of two manuscripts describing STEM teachers' orientations to science teaching through engineering within the context of the Science Learning through Engineering Design (SLED) partnership. The framework guiding both studies was science teaching orientations, a component of pedagogical content knowledge. Data were collected via semi-structured interviews, multi-day classroom observations, pre- and post-observation interviews, implementation plans, and written reflections. Data sources were analyzed to generate two orientations to science teaching through engineering design for each participant. The first manuscript illustrates a single case study conducted with a sixth grade STEM teacher. Results of this study revealed a detailed picture of the teacher's goals, practices, assessments, and general views when teaching science through engineering design. Common themes across the teacher's instruction were used to characterize her orientations to science teaching through engineering design. Overall, the teacher's orientations showed a shift in her practice from didactic to student-centered methods of teaching as a result of integrating engineering design-based curriculum. The second manuscript describes a comparative case study of two sixth grade SLED participants. Results of this study revealed more complex and diverse relationships between the teachers' orientations to teaching science through engineering design and their instruction. Participants' orientations served as filters for instruction, guided by their divergent purposes for science teaching. Furthermore, their orientations and resulting implementation were developed from knowledge gained in teacher education, implying that teacher educators and researchers can use this framework to learn more about how teachers' knowledge is used to integrate engineering and science practices in the K-12 classroom.

2010-12-01

The National Academy of Sciences has created a committee of 18 National Academy of Science and Engineering members, academic scientists, cognitive and learning scientists, and educators, educational policymakers and researchers to develop a framework to guide new K-12 science education standards. The committee began its work in January, 2010, released a draft of the framework in July, 2010, and intends to have the final framework in the first quarter of 2011. The committee was helped in early phases of the work by consultant design teams. The framework is designed to help realize a vision for science and engineering education in which all students actively engage in science and engineering practices in order to deepen their understanding of core ideas in science over multiple years of school. These three dimensions - core disciplinary ideas, science and engineering practices, and cross-cutting elements - must blend together to build an exciting, relevant, and forward looking science education. The framework will be used as a base for development of next generation K-12 science education standards.

Aranda, Maurina L.; Lie, Richard; Selcen Guzey, S.; Makarsu, Murat; Johnston, Amanda; Moore, Tamara J.

2018-03-01

Recent science education reforms highlight the importance for teachers to implement effective instructional practices that promote student learning of science and engineering content and their practices. Effective classroom discussion has been shown to support the learning of science, but work is needed to examine teachers' enactment of engineering design-based science curricula by focusing on the content, complexity, structure, and orchestration of classroom discussions. In the present study, we explored teacher-student talk with respect to science in a middle school curriculum focused on genetics and genetic engineering. Our study was guided by the following major research question: What are the similarities and differences in teacher talk moves that occurred within an engineering design-based science unit enacted by two teachers? Through qualitative and quantitative approaches, we found that there were clear differences in two teachers' use of questioning strategies and presentation of new knowledge that affected the level of student involvement in classroom discourse and the richness and details of student contributions to the conversations. We also found that the verbal explanations of science content differed between two teachers. Collectively, the findings in this study demonstrate that although the teachers worked together to design an engineering designed-based science curriculum unit, their use of different discussion strategies and patterns, and interactions with students differed to affect classroom discourse.

2017-01-01

In the realm of aerospace engineering and the physical sciences, we have developed laws of physics based on empirical and research evidence that reliably guide design, research, and development efforts. For instance, an engineer designs a system based on data and experience that can be consistently and repeatedly verified. This reproducibility depends on the consistency and dependability of the materials on which the engineer works and is subject to physics, geometry and convention. In life sciences and medicine, these apply as well, but individuality introduces a host of variables into the mix, resulting in characteristics and outcomes that can be quite broad within a population of individuals. This individuality ranges from differences at the genetic and cellular level to differences in an individuals personality and abilities due to sex and gender, environment, education, etc.

First-year engineering students' views of the nature of engineering

NASA Astrophysics Data System (ADS)

Karatas, Faik O.

The changing nature of engineering problems and new challenges that result from globalization and new ways of doing business have triggered calls for a revolutionary shift in engineering education. To respond to these challenges, the engineering education paradigm has been revised by adding more design and humanities/social sciences components to it. Philosophy, sociology, and history of engineering are more often cited as a major part of engineering education in this movement. Research on the nature of engineering (NOE), which is derived from philosophy, sociology, and the history of engineering, could have as much potential impact on engineering education as research on the nature of science (NOS) has had on science education. Thus, it is surprising that there has been no noteworthy research on this topic. The purpose of this study is to describe and determine first-year engineering students' views of the NOE and how these students differentiate engineering from science. In this research, an open-ended Views of the Nature of Engineering questionnaire (VNOE) was employed to collect baseline data. Semi-structured interviews based on the VNOE questionnaire were conducted with the second cohort of the participants. Data analysis was guided by a traditional phenomenographic approach, which is a branch of the hermeneutic tradition, coupled to constant comparison technique. The results of this study indicated that the participants' overall views of the nature of engineering were not ill-developed, but rather unarticulated. Moreover, the relationship between engineering and science was considered unidirectional rather than bidirectional. The results of this study could be used to inform engineering educators, first-year engineering coordinators, and policy makers as well as serving as the base for further research and potential implications for future first-year and K-12 engineering education.

STEMujeres: A case study of the life stories of first-generation Latina engineers and scientists

NASA Astrophysics Data System (ADS)

Vielma, Karina I.

Research points to the many obstacles that first-generation, Latina students face when attempting to enter fields in science, technology, engineering, and mathematics, STEM. This qualitative, case study examined the personal and educational experiences of first-generation Latina women who successfully navigated the STEM educational pipeline earning bachelor's, master's, and doctoral degrees in various fields of engineering. Three research questions guided the study: (1) How does a first-generation Latina engineer and scientist describe her life experiences as she became interested in STEM? (2) How does she describe her educational experiences as she navigated the educational pipeline in the physics, mathematics, and/or engineering field(s)? (3) How did she respond to challenges, obstacles and microaggressions, if any, while navigating the STEM educational pipeline? The study was designed using a combination of Critical Race Theory frameworks---Chicana feminist theory and racial microaggressions. Through a life history case study approach, the women shared their stories of success. With the participants' help, influential persons in their educational paths were identified and interviewed. Data were analyzed using crystallization and thematic results indicated that all women in this study identified their parents as planting the seed of interest through the introduction of mathematics. The women unknowingly prepared to enter the STEM fields by taking math and science coursework. They were guided to apply to STEM universities and academic programs by others who knew about their interest in math and science including teachers, counselors, and level-up peers---students close in age who were just a step more advanced in the educational pipeline. The women also drew from previous familial struggles to guide their perseverance and motivation toward educational degree completion. The lives of the women where complex and intersected with various forms of racism including gender, race, class, legality and power. In many instances, the women used their knowledge to help other STEMujeres advance.

Responses to different types of inquiry prompts: college students' discourse, performance, and perceptions of group work in an engineering class

NASA Astrophysics Data System (ADS)

Balgopal, Meena M.; Casper, Anne Marie A.; Atadero, Rebecca A.; Rambo-Hernandez, Karen E.

2017-08-01

Working in small groups to solve problems is an instructional strategy that allows university students in science, technology, engineering, and mathematics disciplines the opportunity to practice interpersonal and professional skills while gaining and applying discipline-specific content knowledge. Previous research indicates that not all group work prompts result in the same experiences for students. In this study we posed two types of prompts (guided and open) to undergraduate engineering students in a statics course as they participated in group work projects. We measured student discourse, student performance, and perceptions of group work. We found that guided prompts were associated with higher-level discourse and higher performance (project scores) than open prompts. Students engaged in guided prompts were more likely to discuss distribution of labour and design/calculation details of their projects than when students responded to open prompts. We posit that guided prompts, which more clearly articulate expectations of students, help students determine how to divide tasks amongst themselves and, subsequently, jump to higher levels of discourse.

Engineering approaches to immunotherapy.

2012-08-22

As the science of immunology grows increasingly mechanistic, motivation for developing quantitative, design-based engineering approaches has also evolved, both for therapeutic interventions and for elucidating immunological pathways in human disease. This has seeded the nascent field of "immunoengineering," which seeks to apply engineering analyses and design approaches to problems in translational immunology. For example, cell engineers are creating ways to tailor and use immune cells as living therapeutics; protein engineers are devising new methods of rapid antibody discovery; biomaterials scientists are guiding vaccine delivery and immune-cell activation with novel constructs; and systems immunologists are deciphering the evolution and maintenance of T and B cell receptor repertoires, which could help guide vaccine design. The field is multidisciplinary and collaborative, with engineers and immunologists working together to better understand and treat disease. We discuss the scientific progress in this young, yet rapidly evolving research area, which has yielded numerous start-up companies that are betting on impact in clinical and commercial translation in the near future.

Kaboli, Saeed; Babazada, Hasan

2018-01-01

The CRISPR (clustered regularly interspaced short palindromic repeat)-Cas9 (CRISPR-associated nuclease 9) method has been dramatically changing the field of genome engineering. It is a rapid, highly efficient and versatile tool for precise modification of genome that uses a guide RNA (gRNA) to target Cas9 to a specific sequence. This novel RNA-guided genome-editing technique has become a revolutionary tool in biomedical science and has many innovative applications in different fields. In this review, we briefly introduce the Cas9-mediated genome-editing tool, summarize the recent advances in CRISPR/Cas9 technology to engineer the genomes of a wide variety of organisms, and discuss their applications to treatment of fungal and viral disease. We also discuss advantageous of CRISPR/Cas9 technology to drug design, creation of animal model, and to food, agricultural and energy sciences. Adoption of the CRISPR/Cas9 technology in biomedical and biotechnological researches would create innovative applications of it not only for breeding of strains exhibiting desired traits for specific industrial and medical applications, but also for investigation of genome function.

!Claro, se puede! Critical resilience: A critical race perspective on resilience in the baccalaureate achievement of Latino/a engineering and life science students

NASA Astrophysics Data System (ADS)

Cruz, Gary Anthony

An under representation of Latino/as in the fields of science, technology, engineering and math (STEM) still persists. In Rising Above the Gathering Storm, the National Academies sounded an alarm in response to data indicating a "troubling decline" in the number of U.S. citizens trained to become scientists and engineers at a time when the number of technical jobs is outpacing the rate of the U.S. workforce. The shrinking technical talent pipeline threatens the country's future in technology innovation, energy alternatives, national security, and education. This study purported to contextualize resilience and discern the cultural capital and persistence behaviors of STEM Latino/a students succeeding in two adverse environments---higher education and science and engineering. Through a critical race perspective the student cuentos were thematically analyzed. Student narratives were then triangulated with the narrative of the researcher---a Mexican American, first-generation college student, who pursued a life science bachelor's degree through the two institutions in this study. The theoretical framework was guided by Critical Race Theory, Resiliency, Persistence Theory, and Social Construction of Technology. The study consisted of a pilot survey and narrative inquiry. The survey contained pilot questions on the use and perception of information technologies in STEM education. The narrative inquiry was guided by critical race that enabled both positionality and storytelling through narratives and counter-narratives. Twenty-two Latino/a graduating seniors majoring in the biological sciences or engineering/engineering technology at a Hispanic-Serving Institution (HSI) and a Predominantly-White Institution (PWI) in Texas were recruited. The narratives of these students were collected through one-time, semi-structured interviews during the last semester of their studies. Results from the study indicate that these Latino/a STEM students are conscious of their ethnicity; however, they are not critically conscious of the master narrative of what it means to be a Latino/a in a STEM discipline. These students have bought into the master narrative of colorblind science and engineering. The students understood that to succeed in STEM, they had to survive based on their proficiency with institutional norms, practices and cultures and then maintain a sense of self through a respect for their Latino culture.

The effects of using guided notes and review of science achievement for male and female students

The National Science Foundation predicts a shortage of scientists and engineers within the next 15 years. Some agree that the participation of women in science will be required to help meet the future demand for scientists (Malcom, 1990). Consequently, conscientious teachers search for learning strategies that provide opportunities for young women to achieve success with others in their science classes. This research concerns a note taking and teaching strategy that involves seventh grade science students. The investigation measured student achievement under three prescribed conditions. The treatment conditions were reviewing, guided notes, and guided notes with reviewing. For this experiment, the Solomon four-group design was utilized. This 2 x 2 factorial design tested for treatment effect and pretest sensitivity. Data was collected on seventh grade boys (n = 119) and seventh grade girls (n = 139) in science. Comparisons were made between the boys and girls groups. The results showed that achievement improved significantly when reviewing car using guided notes independently. The results also shower that significant improvements in achievement were not observed when participants used guided notes and reviewing together. Analysis was completed to measure how well the participants performed according to gender. This research showed that both boys and girls significantly improved their achievement in science equally well for all treatment conditions. This research went a step further by factoring in cognitive ability test scores and comparing them to the treatment results. This provided the researcher with information on which treatment condition worked best for high or low achieving students.

Developing an Engineering Design Process Assessment using Mixed Methods.

PubMed

Wind, Stefanie A; Alemdar, Meltem; Lingle, Jeremy A; Gale, Jessica D; Moore, Roxanne A

Recent reforms in science education worldwide include an emphasis on engineering design as a key component of student proficiency in the Science, Technology, Engineering, and Mathematics disciplines. However, relatively little attention has been directed to the development of psychometrically sound assessments for engineering. This study demonstrates the use of mixed methods to guide the development and revision of K-12 Engineering Design Process (EDP) assessment items. Using results from a middle-school EDP assessment, this study illustrates the combination of quantitative and qualitative techniques to inform item development and revisions. Overall conclusions suggest that the combination of quantitative and qualitative evidence provides an in-depth picture of item quality that can be used to inform the revision and development of EDP assessment items. Researchers and practitioners can use the methods illustrated here to gather validity evidence to support the interpretation and use of new and existing assessments.

Engineering good: how engineering metaphors help us to understand the moral life and change society.

Engineering can learn from ethics, but ethics can also learn from engineering. In this paper, I discuss what engineering metaphors can teach us about practical philosophy. Using metaphors such as calculation, performance, and open source, I articulate two opposing views of morality and politics: one that relies on images related to engineering as science and one that draws on images of engineering practice. I argue that the latter view and its metaphors provide a more adequate way to understand and guide the moral life. Responding to two problems of alienation and taking into account developments such as Fab Lab I then further explore the implications of this view for engineering and society.

Improving Student Writing: Methods You Can Use in Science and Engineering Classrooms

NASA Astrophysics Data System (ADS)

Hitt, S. J.; Bright, K.

2013-12-01

Many educators in the fields of science and engineering assure their students that writing is an important and necessary part of their work. According to David Lindsay, in Scientific Writing=Thinking in Words, 99% of scientists agree that writing is an integral part of their jobs. However, only 5% of those same scientists have ever had formal instruction in scientific writing, and those who are also educators may then feel unconfident in teaching this skill to their students (2). Additionally, making time for writing instruction in courses that are already full of technical content can cause it to be hastily and/or peremptorily included. These situations may be some of the contributing factors to the prevailing attitude of frustration that pervades the conversation about writing in science and engineering classrooms. This presentation provides a summary of past, present, and ongoing Writing Center research on effective writing tutoring in order to give science and engineering educators integrated approaches for working with student writers in their disciplines. From creating assignments, providing instruction, guiding revisions, facilitating peer review, and using assessments, we offer a comprehensive approach to getting your students motivated to improve their writing. Our new research study focuses on developing student writing resources and support in science and engineering institutions, with the goal of utilizing cross-disciplinary knowledge that can be used by the various constituencies responsible for improving the effectiveness of writing among student engineers and scientists. We will will draw upon recent findings in the study of the rhetoric and compositional pedagogy and apply them to the specific needs of the science and engineering classroom. The fields of communication, journalism, social sciences, rhetoric, technical writing, and philosophy of science have begun to integrate these findings into classroom practice, and we will show how these can also benefit educators in science and engineering, with the goal of producing more effective student writing.

Understanding the Role of Academic Language on Conceptual Understanding in an Introductory Materials Science and Engineering Course

NASA Astrophysics Data System (ADS)

Kelly, Jacquelyn

Students may use the technical engineering terms without knowing what these words mean. This creates a language barrier in engineering that influences student learning. Previous research has been conducted to characterize the difference between colloquial and scientific language. Since this research had not yet been applied explicitly to engineering, conclusions from the area of science education were used instead. Various researchers outlined strategies for helping students acquire scientific language. However, few examined and quantified the relationship it had on student learning. A systemic functional linguistics framework was adopted for this dissertation which is a framework that has not previously been used in engineering education research. This study investigated how engineering language proficiency influenced conceptual understanding of introductory materials science and engineering concepts. To answer the research questions about engineering language proficiency, a convenience sample of forty-one undergraduate students in an introductory materials science and engineering course was used. All data collected was integrated with the course. Measures included the Materials Concept Inventory, a written engineering design task, and group observations. Both systemic functional linguistics and mental models frameworks were utilized to interpret data and guide analysis. A series of regression analyses were conducted to determine if engineering language proficiency predicts group engineering term use, if conceptual understanding predicts group engineering term use, and if conceptual understanding predicts engineering language proficiency. Engineering academic language proficiency was found to be strongly linked to conceptual understanding in the context of introductory materials engineering courses. As the semester progressed, this relationship became even stronger. The more engineering concepts students are expected to learn, the more important it is that they are proficient in engineering language. However, exposure to engineering terms did not influence engineering language proficiency. These results stress the importance of engineering language proficiency for learning, but warn that simply exposing students to engineering terms does not promote engineering language proficiency.

2016-12-01

Canadian Indigenous people are an extremely poorly represented group in STEM today due to major barriers in obtaining a high school and then a university education. Approximately 10% of the undergraduate student population out of a total 12,600 students at the University of Regina, Regina, Saskatchewan, is First Nations, Métis or Inuit. The university is located in a catchment region where 30% of the population is First Nations or Métis. Approximately 100 students majoring in the sciences, mathematics and engineering have self-declared themselves to be Indigenous. For the past two years, we have been running a pilot project, the Initiative to Support and Increase the Number of Indigenous Students in the Sciences, Mathematics and Engineering at the Aboriginal Student Centre, with financial support from the Deans of Science and Engineering. We provide student networking lunches, Indigenous scientist and engineer speakers and mentors and supplemental tutoring. Our program is actively supported and guided by Elder Noel Starblanket, former president of the National Indian Brotherhood (now the Assembly of First Nations). Our students are greatly interested in the health and environmental sciences (particularly water quality), with a sprinkling of physics, mathematics and engineering majors. Our students have gone on to graduate work with prestigious scholarships and a paid internship in engineering. We report here on various lessons learned: the involvement of elders is key, as is the acceptance of non-traditional academic paths, and any STEM support program must respect Indigenous culture. There is great interest in science and engineering on the part of these students, if scientists and engineers are willing to listen and learn to talk with these students on their own terms.

Aequilibrium prudentis: on the necessity for ethics and policy studies in the scientific and technological education of medical professionals.

PubMed

Anderson, Misti Ault; Giordano, James

2013-04-23

The importance of strong science, technology, engineering, and mathematics education continues to grow as society, medicine, and the economy become increasingly focused and dependent upon bioscientific and technological innovation. New advances in frontier sciences (e.g., genetics, neuroscience, bio-engineering, nanoscience, cyberscience) generate ethical issues and questions regarding the use of novel technologies in medicine and public life. In light of current emphasis upon science, technology, engineering, and mathematics education (at the pre-collegiate, undergraduate, graduate, and professional levels), the pace and extent of advancements in science and biotechnology, the increasingly technological orientation and capabilities of medicine, and the ways that medicine - as profession and practice - can engage such scientific and technological power upon the multi-cultural world-stage to affect the human predicament, human condition, and perhaps nature of the human being, we argue that it is critical that science, technology, engineering, and mathematics education go beyond technical understanding and directly address ethical, legal, social, and public policy implications of new innovations. Toward this end, we propose a paradigm of integrative science, technology, ethics, and policy studies that meets these needs through early and continued educational exposure that expands extant curricula of science, technology, engineering, and mathematics programs from the high school through collegiate, graduate, medical, and post-graduate medical education. We posit a synthetic approach that elucidates the historical, current, and potential interaction of scientific and biotechnological development in addition to the ethico-legal and social issues that are important to educate and sustain the next generation of medical and biomedical professionals who can appreciate, articulate, and address the realities of scientific and biotechnological progress given the shifting architectonics of the global social milieu. We assert that current trends in science, technology, medicine, and global politics dictate that these skills will be necessary to responsibly guide ethically sound employment of science, technology, and engineering advancements in medicine so as to enable more competent and humanitarian practice within an increasingly pluralistic world culture.

Designing computer learning environments for engineering and computer science: The scaffolded knowledge integration framework

NASA Astrophysics Data System (ADS)

Linn, Marcia C.

1995-06-01

Designing effective curricula for complex topics and incorporating technological tools is an evolving process. One important way to foster effective design is to synthesize successful practices. This paper describes a framework called scaffolded knowledge integration and illustrates how it guided the design of two successful course enhancements in the field of computer science and engineering. One course enhancement, the LISP Knowledge Integration Environment, improved learning and resulted in more gender-equitable outcomes. The second course enhancement, the spatial reasoning environment, addressed spatial reasoning in an introductory engineering course. This enhancement minimized the importance of prior knowledge of spatial reasoning and helped students develop a more comprehensive repertoire of spatial reasoning strategies. Taken together, the instructional research programs reinforce the value of the scaffolded knowledge integration framework and suggest directions for future curriculum reformers.

From Engineering Hydrology to Earth System Science: Milestones in the Transformation of Hydrologic Science (Alfred Wegener Medal Lecture)

NASA Astrophysics Data System (ADS)

Sivapalan, Murugesu

2017-04-01

Hydrologic science has undergone almost transformative changes over the past 50 years. Huge strides have been made in the transition from early empirical approaches to rigorous approaches based on the fluid mechanics of water movement on and below the land surface. However, further progress has been hampered by problems posed by the presence of heterogeneity, especially subsurface heterogeneity, at all scales. The inability to measure or map subsurface heterogeneity everywhere prevented further development of balance equations and associated closure relations at the scales of interest, and has led to the virtual impasse we are presently in, in terms of development of physically based models needed for hydrologic predictions. An alternative to the mapping of subsurface heterogeneity everywhere is a new earth system science view, which sees the heterogeneity as the end result of co-evolutionary hydrological, geomorphological, ecological and pedological processes, each operating at a different rate, which have helped to shape the landscapes that we see in nature, including the heterogeneity below that we do not see. The expectation is that instead of specifying exact details of the heterogeneity in our models, we can replace it, without loss of information, with the ecosystem function they perform. Guided by this new earth system science perspective, development of hydrologic science is now guided by altogether new questions and new approaches to address them, compared to the purely physical, fluid mechanics based approaches that we inherited from the past. In the emergent Anthropocene, the co-evolutionary view is expanded further to involve interactions and feedbacks with human-social processes as well. In this lecture, I will present key milestones in the transformation of hydrologic science from Engineering Hydrology to Earth System Science, and what this means for hydrologic observations, theory development and predictions.

The University of Texas at San Antonio (UTSA), San Antonio College (SAC), and the University of North Dakota (UND) have partnered with NASA to provide underrepresented undergraduates from UTSA, SAC, and other community colleges climate-related research and education experiences through the Climate Change Communication: Engineer, Environmental science, and Education (C3E3) project. The program aims to develop a robust response to climate change by providing K-16 climate change education; enhance the effectiveness of K-16 education particularly in engineering and other STEM disciplines by use of new instructional technologies; increase the enrollment in engineering programs and the number of engineering degrees awarded by showing engineering's usefulness in relation to the much-discussed contemporary issue of climate change; increase persistence in STEM degrees by providing student research opportunities; and increase the ethnic diversity of those receiving engineering degrees and help ensure an ethnically diverse response to climate change. Students participated in the second summer internship funded by the project. The program is in its third year. More than 75 students participated in a guided research experiences aligned with NASA Science Plan objectives for climate and Earth system science and the educational objectives of the three institutions. The students went through training in modern media technology (webcasts), and in using this technology to communicate the information on climate change to others, especially high school students, culminating in production of webcasts on investigating the aspects of climate change using NASA data. Content developed is leveraged by NASA Earth observation data and NASA Earth system models and tools. Three Colleges were involved in the program: Engineering, Education, and Science.

Sahin, Alpaslan; Gulacar, Ozcan; Stuessy, Carol

2015-12-01

Social cognitive theory guided the design of a survey to investigate high school students' perceptions of factors affecting their career contemplations and beliefs regarding the influence of their participation in the international Science Olympiad on their subject interests and twenty-first century skills. In addition, gender differences in students' choice of competition category were studied. Mixed methods analysis of survey returns from 172 Olympiad participants from 31 countries showed that students' career aspirations were affected most by their teachers, personal interests, and parents, respectively. Students also indicated that they believed that their participation in the Olympiad reinforced their plan to choose a science, technology, engineering, and mathematics (STEM) major at college and assisted them in developing and improving their twenty-first century skills. Furthermore, female students' responses indicated that their project choices were less likely to be in the engineering category and more likely to be in the environment or energy categories. Findings are discussed in the light of increasing the awareness of the role and importance of Science Olympiads in STEM career choice and finding ways to attract more female students into engineering careers.

Girls Entering Technology, Science, Math and Research Training (get Smart): a Model for Preparing Girls in Science and Engineering Disciplines

NASA Astrophysics Data System (ADS)

Mawasha, P. Ruby; Lam, Paul C.; Vesalo, John; Leitch, Ronda; Rice, Stacey

In this article, it is postulated that the development of a successful training program for women in science, math, engineering, and technology (SMET) disciplines is dependent upon a combination of several factors, including (a) career orientation: commitment to SMET as a career, reasons for pursuing SMET as a career, and opportunity to pursue a SMET career; (b) knowledge of SMET: SMET courses completed, SMET achievement, and hands-on SMET activities; (c) academic and social support: diversity initiatives, role models, cooperative learning, and peer counseling; and (d) self-concept: program emphasis on competence and peer competition. The proposed model is based on the GET SMART (Girls Entering Technology, Science, Math and Research Training) workshop program to prepare and develop female high school students as competitive future SMET professionals. The proposed model is not intended to serve as an elaborate theory, but as a general guide in training females entering SMET disciplines.

"Finding the Joy in the Unknown": Implementation of STEAM Teaching Practices in Middle School Science and Math Classrooms

2016-06-01

In response to a desire to strengthen the economy, educational settings are emphasizing science, technology, engineering, and mathematics (STEM) curriculum and programs. Yet, because of the narrow approach to STEM, educational leaders continue to call for a more balanced approach to teaching and learning, which includes the arts, design, and humanities. This desire created space for science, technology, engineering, arts, and mathematics (STEAM) education, a transdisciplinary approach that focuses on problem-solving. STEAM-based curricula and STEAM-themed schools are appearing all over the globe. This growing national and global attention to STEAM provides an opportunity for teacher education to explore the ways in which teachers implement STEAM practices, examining the successes and challenges, and how teachers are beginning to make sense of this innovative teaching practice. The purpose of this paper is to examine the implementation of STEAM teaching practices in science and math middle school classrooms, in hopes to provide research-based evidence on this emerging topic to guide teacher educators.

Machine learning and data science in soft materials engineering

NASA Astrophysics Data System (ADS)

Ferguson, Andrew L.

2018-01-01

In many branches of materials science it is now routine to generate data sets of such large size and dimensionality that conventional methods of analysis fail. Paradigms and tools from data science and machine learning can provide scalable approaches to identify and extract trends and patterns within voluminous data sets, perform guided traversals of high-dimensional phase spaces, and furnish data-driven strategies for inverse materials design. This topical review provides an accessible introduction to machine learning tools in the context of soft and biological materials by ‘de-jargonizing’ data science terminology, presenting a taxonomy of machine learning techniques, and surveying the mathematical underpinnings and software implementations of popular tools, including principal component analysis, independent component analysis, diffusion maps, support vector machines, and relative entropy. We present illustrative examples of machine learning applications in soft matter, including inverse design of self-assembling materials, nonlinear learning of protein folding landscapes, high-throughput antimicrobial peptide design, and data-driven materials design engines. We close with an outlook on the challenges and opportunities for the field.

Our understanding of cell biology and its integration with materials science has led to technological innovations in the bioengineering of tissue-mimicking grafts that can be utilized in clinical and pharmaceutical applications. Bio-engineering of native-like multiscale building blocks provides refined control over the cellular microenvironment, thus enabling functional tissues. In this review, we focus on assembling building blocks from the biomolecular level to the millimeter scale. We also provide an overview of techniques for assembling molecules, cells, spheroids, and microgels and achieving bottom-up tissue engineering. Additionally, we discuss driving mechanisms for self- and guided assembly to create micro-to-macro scale tissue structures. PMID:25796488

Aequilibrium prudentis: on the necessity for ethics and policy studies in the scientific and technological education of medical professionals

PubMed Central

2013-01-01

Background The importance of strong science, technology, engineering, and mathematics education continues to grow as society, medicine, and the economy become increasingly focused and dependent upon bioscientific and technological innovation. New advances in frontier sciences (e.g., genetics, neuroscience, bio-engineering, nanoscience, cyberscience) generate ethical issues and questions regarding the use of novel technologies in medicine and public life. Discussion In light of current emphasis upon science, technology, engineering, and mathematics education (at the pre-collegiate, undergraduate, graduate, and professional levels), the pace and extent of advancements in science and biotechnology, the increasingly technological orientation and capabilities of medicine, and the ways that medicine – as profession and practice – can engage such scientific and technological power upon the multi-cultural world-stage to affect the human predicament, human condition, and perhaps nature of the human being, we argue that it is critical that science, technology, engineering, and mathematics education go beyond technical understanding and directly address ethical, legal, social, and public policy implications of new innovations. Toward this end, we propose a paradigm of integrative science, technology, ethics, and policy studies that meets these needs through early and continued educational exposure that expands extant curricula of science, technology, engineering, and mathematics programs from the high school through collegiate, graduate, medical, and post-graduate medical education. We posit a synthetic approach that elucidates the historical, current, and potential interaction of scientific and biotechnological development in addition to the ethico-legal and social issues that are important to educate and sustain the next generation of medical and biomedical professionals who can appreciate, articulate, and address the realities of scientific and biotechnological progress given the shifting architectonics of the global social milieu. Summary We assert that current trends in science, technology, medicine, and global politics dictate that these skills will be necessary to responsibly guide ethically sound employment of science, technology, and engineering advancements in medicine so as to enable more competent and humanitarian practice within an increasingly pluralistic world culture.

Project-oriented teaching model about specialized courses in the information age

NASA Astrophysics Data System (ADS)

Chen, Xiaodong; Wang, Jinjiang; Tian, Qingguo; Wang, Yi; Cai, Huaiyu

2017-08-01

Specialized courses play a significant role in the usage of basic knowledge in the practical application for engineering college students. The engineering data available has sharply increased since the beginning of the information age in the 20th century, providing much more approaches to study and practice. Therefore, how to guide students to make full use of resources for active engineering practice learning has become one of the key problems for specialized courses. This paper took the digital image processing course for opto-electronic information science and technology major as an example, discussed the teaching model of specialized course in the information age, put forward the "engineering resource oriented model", and fostered the ability of engineering students to use the basic knowledge to innovate and deal with specific project objectives. The fusion of engineering examples into practical training and teaching encourages students to practice independent engineering thinking.

Fault Management Guiding Principles

NASA Technical Reports Server (NTRS)

Newhouse, Marilyn E.; Friberg, Kenneth H.; Fesq, Lorraine; Barley, Bryan

2011-01-01

Regardless of the mission type: deep space or low Earth orbit, robotic or human spaceflight, Fault Management (FM) is a critical aspect of NASA space missions. As the complexity of space missions grows, the complexity of supporting FM systems increase in turn. Data on recent NASA missions show that development of FM capabilities is a common driver for significant cost overruns late in the project development cycle. Efforts to understand the drivers behind these cost overruns, spearheaded by NASA's Science Mission Directorate (SMD), indicate that they are primarily caused by the growing complexity of FM systems and the lack of maturity of FM as an engineering discipline. NASA can and does develop FM systems that effectively protect mission functionality and assets. The cost growth results from a lack of FM planning and emphasis by project management, as well the maturity of FM as an engineering discipline, which lags behind the maturity of other engineering disciplines. As a step towards controlling the cost growth associated with FM development, SMD has commissioned a multi-institution team to develop a practitioner's handbook representing best practices for the end-to-end processes involved in engineering FM systems. While currently concentrating primarily on FM for science missions, the expectation is that this handbook will grow into a NASA-wide handbook, serving as a companion to the NASA Systems Engineering Handbook. This paper presents a snapshot of the principles that have been identified to guide FM development from cradle to grave. The principles range from considerations for integrating FM into the project and SE organizational structure, the relationship between FM designs and mission risk, and the use of the various tools of FM (e.g., redundancy) to meet the FM goal of protecting mission functionality and assets.

Europa Explorer Operational Scenarios Development

Lock, Robert E.; Pappalardo, Robert T.; Clark, Karla B.

2008-01-01

In 2007, NASA conducted four advanced mission concept studies for outer planets targets: Europa, Ganymede, Titan and Enceladus. The studies were conducted in close cooperation with the planetary science community. Of the four, the Europa Explorer Concept Study focused on refining mission options, science trades and implementation details for a potential flagship mission to Europa in the 2015 timeframe. A science definition team (SDT) was appointed by NASA to guide the study. A JPL-led engineering team worked closely with the science team to address 3 major focus areas: 1) credible cost estimates, 2) rationale and logical discussion of radiation risk and mitigation approaches, and 3) better definition and exploration of science operational scenario trade space. This paper will address the methods and results of the collaborative process used to develop Europa Explorer operations scenarios. Working in concert with the SDT, and in parallel with the SDT's development of a science value matrix, key mission capabilities and constraints were challenged by the science and engineering members of the team. Science goals were advanced and options were considered for observation scenarios. Data collection and return strategies were tested via simulation, and mission performance was estimated and balanced with flight and ground system resources and science priorities. The key to this successful collaboration was a concurrent development environment in which all stakeholders could rapidly assess the feasibility of strategies for their success in the full system context. Issues of science and instrument compatibility, system constraints, and mission opportunities were treated analytically and objectively leading to complementary strategies for observation and data return. Current plans are that this approach, as part of the system engineering process, will continue as the Europa Explorer Concept Study moves toward becoming a development project.

Learning to Teach Elementary Science Through Iterative Cycles of Enactment in Culturally and Linguistically Diverse Contexts

NASA Astrophysics Data System (ADS)

Bottoms, SueAnn I.; Ciechanowski, Kathryn M.; Hartman, Brian

2015-12-01

Iterative cycles of enactment embedded in culturally and linguistically diverse contexts provide rich opportunities for preservice teachers (PSTs) to enact core practices of science. This study is situated in the larger Families Involved in Sociocultural Teaching and Science, Technology, Engineering and Mathematics (FIESTAS) project, which weaves together cycles of enactment, core practices in science education and culturally relevant pedagogies. The theoretical foundation draws upon situated learning theory and communities of practice. Using video analysis by PSTs and course artifacts, the authors studied how the iterative process of these cycles guided PSTs development as teachers of elementary science. Findings demonstrate how PSTs were drawing on resources to inform practice, purposefully noticing their practice, renegotiating their roles in teaching, and reconsidering "professional blindness" through cultural practice.

Optimization of a multi-channel parabolic guide for the material science diffractometer STRESS-SPEC at FRM II

NASA Astrophysics Data System (ADS)

Rebelo Kornmeier, Joana; Ostermann, Andreas; Hofmann, Michael; Gibmeier, Jens

2014-02-01

Neutron strain diffractometers usually use slits to define a gauge volume within engineering samples. In this study a multi-channel parabolic neutron guide was developed to be used instead of the primary slit to minimise the loss of intensity and vertical definition of the gauge volume when using slits placed far away from the measurement position in bulky components. The major advantage of a focusing guide is that the maximum flux is not at the exit of the guide as for a slit system but at the focal point relatively far away from the exit of the guide. Monte Carlo simulations were used to optimise the multi-channel parabolic guide with respect to the instrument characteristics of the diffractometer STRESS-SPEC at the FRM II neutron source. Also the simulations are in excellent agreement with experimental measurements using the optimised multi-channel parabolic guide at the neutron diffractometer. In addition the performance of the guide was compared to the standard slit setup at STRESS-SPEC using a single bead weld sample used in earlier round robin tests for residual strain measurements.

Cas9, Cpf1 and C2c1/2/3―What's next?

2017-01-01

ABSTRACT Since the rapid emergence of clustered regulatory interspaced short palindromic repeats (CRISPR)-CRISPR-associated protein 9 (Cas9) system, developed as a genome engineering tool in 2012–2013, most researchers in the life science field have had a fixated interest in this fascinating technology. CRISPR-Cas9 is an RNA-guided DNA endonuclease system, which consists of Cas9 nuclease defining a few targeting base via protospacer adjacent motif complexed with easily customizable single guide RNA targeting around 20-bp genomic sequence. Although Streptococcus pyogenes Cas9 (SpCas9), one of the Cas9 proteins that applications in genome engineering were first demonstrated, still has wide usage because of its high nuclease activity and broad targeting range, there are several limitations such as large molecular weight and potential off-target effect. In this commentary, we describe various improvements and alternatives of CRISPR-Cas systems, including engineered Cas9 variants, Cas9 homologs, and novel Cas proteins other than Cas9. These variations enable flexible genome engineering with high efficiency and specificity, orthogonal genetic control at multiple gene loci, gene knockdown, or fluorescence imaging of transcripts mediated by RNA targeting, and beyond.

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

2017-09-01

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

Asian and Pacific Islander women scientists and engineers: A narrative exploration of model minority, gender, and racial stereotypes

NASA Astrophysics Data System (ADS)

Chinn, Pauline W. U.

2002-04-01

This qualitative study uses narrative methodology to understand what becoming a scientist or engineer entails for women stereotyped as model minorities. Interviews with four Chinese and Japanese women focused on the social contexts in which science is encountered in classrooms, families, and community. Interpretation was guided by theories that individuals construct personal narratives mediated by cultural symbolic systems to make meaning of experiences. Narratives revealed that Confucian cultural scripts shaped gender expectations even in families several generations in America. Regardless of parents' level of education, country of birth, and number of children, educational expectations, and resources were lower for daughters. Parents expected daughters to be compliant, feminine, and educated enough to be marriageable. Findings suggest K-12 gender equity science practices encouraged development of the women's interests and abilities but did not affect parental beliefs. The author's 1999 study of Hawaiians/Pacific Islander and Filipina female engineers is included in implications for teacher education programs sensitive to gender, culture, ethnicity, and language.

There is an urgent need for broad and integrated studies that address the risks of engineered nanomaterials (ENMs) along the different endpoints of the society, environment, and economy (SEE) complex adaptive system. This article presents an integrated science-based methodology to assess the potential risks of engineered nanomaterials. To achieve the study objective, two major tasks are accomplished, knowledge synthesis and algorithmic computational methodology. The knowledge synthesis task is designed to capture "what is known" and to outline the gaps in knowledge from ENMs risk perspective. The algorithmic computational methodology is geared toward the provision of decisions and an understanding of the risks of ENMs along different endpoints for the constituents of the SEE complex adaptive system. The approach presented herein allows for addressing the formidable task of assessing the implications and risks of exposure to ENMs, with the long term goal to build a decision-support system to guide key stakeholders in the SEE system towards building sustainable ENMs and nano-enabled products.

Montaser, Laila M.; Fawzy, Sherin M.

2015-08-01

Tissue engineering and regenerative medicine have been constantly developing of late due to the major progress in cell and organ transplantation, as well as advances in materials science and engineering. Although stem cells hold great potential for the treatment of many injuries and degenerative diseases, several obstacles must be overcome before their therapeutic application can be realized. These include the development of advanced techniques to understand and control functions of micro environmental signals and novel methods to track and guide transplanted stem cells. A major complication encountered with stem cell therapies has been the failure of injected cells to engraft to target tissues. The application of nanotechnology to stem cell biology would be able to address those challenges. Combinations of stem cell therapy and nanotechnology in tissue engineering and regenerative medicine have achieved significant advances. These combinations allow nanotechnology to engineer scaffolds with various features to control stem cell fate decisions. Fabrication of Nano fiber cell scaffolds onto which stem cells can adhere and spread, forming a niche-like microenvironment which can guide stem cells to proceed to heal damaged tissues. In this paper, current and emergent approach based on stem cells in the field of liver tissue engineering is presented for specific application. The combination of stem cells and tissue engineering opens new perspectives in tissue regeneration for stem cell therapy because of the potential to control stem cell behavior with the physical and chemical characteristics of the engineered scaffold environment.

The CASPER Physics Circus was specifically designed to increase student interest in science, technology, engineering and mathematics (STEM) careers where the current generation of scientists and engineers is rapidly approaching retirement age. The Physics Circus followed Waco and LaVega ISD students starting in the sixth grade and ending in the twelfth grade with this cohort group attending the Physics Circus event on the Baylor University campus, interacting with CASPER graduate students and participating in hands-on instructional activities. The event was designed as an informal learning environment intervention and operated under the discovery, project and guided-inquiry base framework wrapped in a learner-center ideology. Participating students were allowed to experiment with hands-on manipulatives while interacting with physicists, science educators and graduate students in both STEM and science education fields. Professional Development was also a part of the Physics Circus for all science teachers within the cohort. This paper presents the results of a seven-year longitudinal study on the Physics Circus and presents future plans to expand the program's effectiveness and impact.

The self-assembly feature of the naturally occurring biopolymer, DNA, has fascinated researchers in the fields of materials science and bioengineering. With the improved understanding of the chemical and structural nature of DNA, DNA-based constructs have been designed and fabricated from two-dimensional arbitrary shapes to reconfigurable three-dimensional nanodevices. Although DNA has been used successfully as a building block in a finely organized and controlled manner, its applications need to be explored. Hence, with the myriad of biological functions, RNA has recently attracted considerable attention to further the application of nucleic acid-based structures. This Review categorizes different approaches of engineering nucleic acid-based structures and introduces the concepts, principles, and applications of each technique, focusing on how DNA engineering is applied as a guide to RNA engineering.

This study investigates the effects of an intensive 1-week Inquiry-Based Science and Technology Enrichment Program (InSTEP) designed for middle school-aged female students. InSTEP uses a guided/open inquiry approach that is deepened and redefined as eight sciences and engineering practices in the Next Generation Science Standards, which aimed at increasing female students' interest in science and science-related careers. This study examined the effectiveness of InSTEP on 123 female students' pre-assessment and post-assessment changes in attitudes toward science and content knowledge of selected science concepts. An attitude survey, a science content test with multiple-choice questions, written assignments, and interviews to collect data were all used to measure students' attitudes and content knowledge. A within-group, repeated measure design was conducted, and the results indicated that at the post-intervention level, InSTEP increased the participants' positive attitudes toward science, science-related careers, and content knowledge of selected science concepts.

It was designed and created by the Engineering is Elementary® team at the Museum of Science in Boston, MA, in collaboration with subject matter experts at the USGS Astrogeology Science Center and teacher professional development experts at Northern Arizona University's Center for Science Teaching and Learning. As part of the NASA-funded PLANETS (Planetary Learning that Advances the Nexus of Engineering, Technology, and Science) project, the goals for this unit are to introduce students to some of the potential hazards that would be faced by astronauts exploring planetary bodies in the solar system, and to engage students in thinking about how to engineer solutions to these challenges. Potential human health hazards in planetary exploration include: little to no breathable oxygen, exposure to extreme temperatures and pressures, radiation, dusty or toxic environments, and/or high velocity debris. First, students experiment with gloves made of different materials to accomplish tasks like picking up paper clips, entering numbers on a calculator, and using simple tools, while also testing for insulating properties, protection from crushing forces, and resistance to dust contamination. Students explore the trade-offs between form and multiple desired functions, and gain an introduction to materials engineering. Students are then presented with three different missions. Mission 1 is to collect and return a sample from Saturn's moon, Titan; Mission 2 is mining asteroids for useful minerals; and Mission 3 is to build a radio tower on the far side of Earth's moon. Each of these missions exhibits different potential hazards. Based on their previous experiments with different types of glove materials, students develop and test glove designs that will protect astronauts from mission-specific hazards, while still retaining basic dexterity and functionality. Educators are given background information and links to in-depth descriptions of the science content, and students are guided through the engineering design process as well as given scientific background on hazards in the solar system in a fun and engaging series of activities.

Opportunities for Scientists to Engage the Public & Inspire Students in Science

Increasingly, research scientists are learning that communicating science to broad, non-specialist audiences, particularly students, is just as important as communicating science to their peers via peer-reviewed scientific publications. This presentation highlights opportunities that scientists in Flagstaff, AZ have to foster public support of science & inspire students to study STEM disciplines. The goal here is to share ideas, personal experiences, & the rewards, for both students & research professionals, of engaging in science education & public outreach. Flagstaff, AZ, "America's First STEM Community," has a uniquely rich community of organizations engaged in science & engineering research & innovation, including the Flagstaff Arboretum, Coconino Community College, Gore Industries, Lowell Observatory, Museum of Northern Arizona, National Weather Service, National Park Service, National Forest Service, Northern Arizona University, Northern Arizona Center for Entrepreneurship & Technology, US Geological Survey, US Naval Observatory, & Willow Bend Environmental Education Center. These organizations connect with the Northern Arizona community during the yearly Flagstaff Festival of Science - the third oldest science festival in the world - a 10 day long, free, science festival featuring daily public lectures, open houses, interactive science & technology exhibits, field trips, & in-school speaker programs. Many research scientists from these organizations participate in these activities, e.g., public lectures, open houses, & in-school speaker programs, & also volunteer as mentors for science & engineering themed clubs in local schools. An example of a novel, innovative program, developed by a local K-12 science teacher, is the "Scientists-in-the-Classroom" mentor program, which pairs all 7th & 8th grade students with a working research scientist for the entire school year. Led by the student & guided by the mentor, they develop a variety of science / technology projects, which the students then present at year's end. From the perspective of an active research scientist, such outreach activities take little time & effort (~ 0.05 FTE), but pay large dividends in the long run, in inciting public support for science & inspiring the next generation of scientists & engineers.

The University of Texas at San Antonio (UTSA), San Antonio College (SAC), and the University of North Dakota (UND) have partnered with NASA to provide underrepresented undergraduates from UTSA, SAC, and other community colleges climate-related research and education experiences through the Climate Change Communication: Engineer, Environmental science, and Education (C3E3) project. The program aims to develop a robust response to climate change by providing K-16 climate change education; enhance the effectiveness of K-16 education particularly in engineering and other STEM disciplines by use of new instructional technologies; increase the enrollment in engineering programs and the number of engineering degrees awarded by showing engineering's usefulness in relation to the much-discussed contemporary issue of climate change; increase persistence in STEM degrees by providing student research opportunities; and increase the ethnic diversity of those receiving engineering degrees and help ensure an ethnically diverse response to climate change. Students participated in the second summer internship funded by the project. More than 60 students participated in guided research experiences aligned with NASA Science Plan objectives for climate and Earth system science and the educational objectives of the three institutions. The students went through training in modern media technology (webcasts), and in using this technology to communicate the information on climate change to others, especially high school students, culminating in production of webcasts on investigating the aspects of climate change using NASA data. Content developed is leveraged by NASA Earth observation data and NASA Earth system models and tools. Several departments are involved in the educational program.

Guided-Inquiry Lessons Raise Scores on the Sixth Grade Georgia Science Test

NASA Astrophysics Data System (ADS)

Page, Purlie M.

At the local level, G Middle School has the highest district-wide percentage of 6th grade science students who are not meeting standards. It is imperative that G middle school take corrective action to reduce the number of students failing to meet state science standards. Dewey's theory of conceptual framework, which involves knowledge constructed on a person's personal experience and mind activity through active forms of learning, guided this study. The goal of the study was to determine whether inquiry-based science modules produce greater 6th grade science achievement, as measured by an equivalent instrument of the science section of the Georgia Criterion-Referenced Competency Test, when compared to traditional instruction among eastern Georgia 6th graders. The sample consisted of 230 students in the nonintervention group and 119 students in the intervention group. All students were from intact classes. At the end of the intervention, an independent t test was conducted to analyze the scores. According to the study t test, (t = 12.33, df = 304.56, p < 0.05), the difference between the means was statistically significant. This project's potential impact on social change includes increasing student motivation towards, comprehension of, and interest in science concepts. At the local level, these inquiry lessons can be shared with science teachers across grade levels and within the district to improve county-wide science scores. An increase in student interest and comprehension of science concepts could ultimately lead to the United States producing more students in the fields of science, technology, engineering, and mathematics (STEM) education.

2018-11-01

Fractional calculus is at this stage an arena where many models are still to be introduced, discussed and applied to real world applications in many branches of science and engineering where nonlocality plays a crucial role. Although researchers have already reported many excellent results in several seminal monographs and review articles, there are still a large number of non-local phenomena unexplored and waiting to be discovered. Therefore, year by year, we can discover new aspects of the fractional modeling and applications. This review article aims to present some short summaries written by distinguished researchers in the field of fractional calculus. We believe this incomplete, but important, information will guide young researchers and help newcomers to see some of the main real-world applications and gain an understanding of this powerful mathematical tool. We expect this collection will also benefit our community.

Atmospheric Risk Assessment for the Mars Science Laboratory Entry, Descent, and Landing System

2010-01-01

In 2012, the Mars Science Laboratory (MSL) mission will pioneer the next generation of robotic Entry, Descent, and Landing (EDL) systems, by delivering the largest and most capable rover to date to the surface of Mars. As with previous Mars landers, atmospheric conditions during entry, descent, and landing directly impact the performance of MSL's EDL system. While the vehicle's novel guided entry system allows it to "fly out" a range of atmospheric uncertainties, its trajectory through the atmosphere creates a variety of atmospheric sensitivities not present on previous Mars entry systems and landers. Given the mission's stringent landing capability requirements, understanding the atmosphere state and spacecraft sensitivities takes on heightened importance. MSL's guided entry trajectory differs significantly from recent Mars landers and includes events that generate different atmospheric sensitivities than past missions. The existence of these sensitivities and general advancement in the state of Mars atmospheric knowledge has led the MSL team to employ new atmosphere modeling techniques in addition to past practices. A joint EDL engineering and Mars atmosphere science and modeling team has been created to identify the key system sensitivities, gather available atmospheric data sets, develop relevant atmosphere models, and formulate methods to integrate atmosphere information into EDL performance assessments. The team consists of EDL engineers, project science staff, and Mars atmospheric scientists from a variety of institutions. This paper provides an overview of the system performance sensitivities that have driven the atmosphere modeling approach, discusses the atmosphere data sets and models employed by the team as a result of the identified sensitivities, and introduces the tools used to translate atmospheric knowledge into quantitative EDL performance assessments.

Materials science. Modeling strain hardening the hard way.

PubMed

Gumbsch, Peter

2003-09-26

The plastic deformation of metals results in strain hardening, that is, an increase in the stress with increasing strain. Materials engineers can provide a simple approximate description of such deformation and hardening behavior. In his perspective, Gumbsch discusses work by Madec et al. who have undertaken the formidable task of computing the physical basis for the development of strain hardening by individually following the fate of all the dislocations involved. Their simulations show that the collinear dislocation interaction makes a substantial contribution to strain hardening. It is likely that such simulations will play an important role in guiding the development of future engineering descriptions of deformation and hardening.

BIOCOMPUTATION: some history and prospects.

PubMed

Cull, Paul

2013-06-01

At first glance, biology and computer science are diametrically opposed sciences. Biology deals with carbon based life forms shaped by evolution and natural selection. Computer Science deals with electronic machines designed by engineers and guided by mathematical algorithms. In this brief paper, we review biologically inspired computing. We discuss several models of computation which have arisen from various biological studies. We show what these have in common, and conjecture how biology can still suggest answers and models for the next generation of computing problems. We discuss computation and argue that these biologically inspired models do not extend the theoretical limits on computation. We suggest that, in practice, biological models may give more succinct representations of various problems, and we mention a few cases in which biological models have proved useful. We also discuss the reciprocal impact of computer science on biology and cite a few significant contributions to biological science. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

The contribution of biological, mathematical, clinical, engineering and social sciences to combatting the West African Ebola epidemic.

Whitty, Christopher J M

2017-05-26

The tragic West African Ebola epidemic claimed many lives, but would have been worse still if scientific insights from many disciplines had not been integrated to create a strong technical response. Epidemiology and modelling triggered the international response and guided where response efforts were directed; virology, engineering and clinical science helped reduce deaths and transmission in and from hospitals and treatment centres; social sciences were key to reducing deaths from funerals and in the community; diagnostic and operational research made the response more efficient; immunology and vaccine research contributed to the final stages of the epidemic and will help prevent future epidemics. These varied scientific contributions had to be integrated into a combined narrative, communicated to policymakers to inform decisions, and used by courageous local and international responders in the field in real time. Not every area of science was optimal, and in particular, clinical trials of simple interventions such as fluid management were slow to be adopted and sharing of data was initially poor. This Ebola epidemic demonstrated how science can respond to a major emergency, but also has lessons for better responses in future infectious emergencies.This article is part of the themed issue 'The 2013-2016 West African Ebola epidemic: data, decision-making and disease control'. © 2017 The Author(s).

Technological innovation in the United States.

Kilgour, F G

1965-01-01

This paper presents nearly three and a half centuries of American invention, and is particularly concerned with primary invention as distinct from development, production, and service engineering. One apparent but not real exception to this statement is that one section will be devoted to the American invention of production engineering. Various factors have stimulated, guided, and inhibited American inventiveness; indeed, colonial status during nearly half the historical period being examined all but stifled technological innovation. It will also become clear that American disenchantment with basic scientific activity diminished the relative magnitude of her innovations after the advent of the technique of applied research in Europe following the middle of the nineteenth century. This circumstance is particularly obvious in the cases of chemical and electrical engineering, the first of the applied sciences.

Science academies were originally created to facilitate science communication and later to recognize excellence. But in the last 20 years some 150 academies of science, engineering,and medicine around the world have united to cooperate in contributing to human welfare, by: 1. Providing evidence-based inputs to national, regional, and global policies addressing human needs, and 2. Conducting cooperative programs to increase the capacity of academies to provide such advice, and to better connect academies to publics and to policy makers. Examples: At the global level, 112 academies of science produce brief common statements on major global issues. They have also created an organization to provide in-depth reports on major issues such as a transition to sustainable energy systems, boosting agricultural productivity in Africa, and a guide to responsible conduct in the global research enterprise. Regional networks of those academies, in Africa, the Americas, Asia, and Europe conduct program on topics such as water, energy, engagement of women in science, and science education. They also help and mentor new academies.

Young Children's Development of Scientific Knowledge Through the Combination of Teacher-Guided Play and Child-Guided Play

NASA Astrophysics Data System (ADS)

Sliogeris, Marija; Almeida, Sylvia Christine

2017-09-01

Play-based approaches to science learning allow children to meaningfully draw on their everyday experiences and activities as they explore science concepts in context. Acknowledging the crucial role of the teacher in facilitating science learning through play, the purpose of this qualitative study was to examine how teacher-guided play, in conjunction with child-guided play, supports children's development of science concepts. While previous research on play-based science learning has mainly focused on preschool settings, this study explores the possibilities of play-based approaches to science in primary school contexts. Using a qualitative methodology grounded in the cultural-historical theoretical perspective, children's learning was examined during a science learning sequence that combined teacher-guided and child-guided play. This study revealed that the teacher-guided play explicitly introduced science concepts which children then used and explored in subsequent child-guided play. However, intentional teaching during the child-guided play continued to be important. Play-based approaches to science allowed children to make sense of the science concepts using familiar, everyday knowledge and activities. It became evident that the expectations and values communicated through classroom practices influenced children's learning through play.

Who Chooses STEM Careers? Using A Relative Cognitive Strength and Interest Model to Predict Careers in Science, Technology, Engineering, and Mathematics.

Wang, Ming-Te; Ye, Feifei; Degol, Jessica Lauren

2017-08-01

Career aspirations in science, technology, engineering, and mathematics (STEM) are formulated in adolescence, making the high school years a critical time period for identifying the cognitive and motivational factors that increase the likelihood of future STEM employment. While past research has mainly focused on absolute cognitive ability levels in math and verbal domains, the current study tested whether relative cognitive strengths and interests in math, science, and verbal domains in high school were more accurate predictors of STEM career decisions. Data were drawn from a national longitudinal study in the United States (N = 1762; 48 % female; the first wave during ninth grade and the last wave at age 33). Results revealed that in the high-verbal/high-math/high-science ability group, individuals with higher science task values and lower orientation toward altruism were more likely to select STEM occupations. In the low-verbal/moderate-math/moderate-science ability group, individuals with higher math ability and higher math task values were more likely to select STEM occupations. The findings suggest that youth with asymmetrical cognitive ability profiles are more likely to select careers that utilize their cognitive strengths rather than their weaknesses, while symmetrical cognitive ability profiles may grant youth more flexibility in their options, allowing their interests and values to guide their career decisions.

Energy balance disorders account for a large public health burden. The obesity epidemic in particular is one of the most rapidly evolving public health problems of our day. At present, two-thirds of American adults and one-sixth of American children and adolescents are considered either overweight or obese. Public health concern about obesity is high because of the increased risk and increased mortality of cardiovascular disease, Type 2 diabetes, many forms of cancer, gallbladder disease, and osteoarthritis. These risks increase with the severity of the obesity. Excess adipose tissue, representing fat storage, ultimately derives from an imbalance between energy intake and energy expenditure. Conversely, undesirable and inadvertent loss of body weight and muscle mass, as seen in aging and cachectic states of chronic diseases such as heart failure and cancer, have serious clinical and functional consequences without satisfactory clinical or behavioral solutions. Innovative engineering technologies could help to address unresolved problems in energy balance, intake, and expenditure. Novel sensors, devices, imaging technologies, nanotechnologies, biomaterials, technologies to detect biochemical markers of energy balance, mathematical modeling, systems biology, and other approaches could be developed, evaluated, and leveraged through multidisciplinary collaborations. Engineers, physical scientists, and mathematicians can work with scientists from other relevant disciplines who possess expertise in obesity and nutrition. Furthermore, the possibility of re-engineering the "built environment" to encourage higher levels of physical activity has been suggested as another promising and important approach to which engineers can contribute (see http://www.obesityresearch.nih.gov). Ultimately, systematic application of the "Engineering Approach" can help in developing the needed technologies and tools to facilitate research and eventually support therapeutic advances and behavioral change. This article summarizes important public health concerns related to disordered energy balance and describes research priorities identified at a recent National Science Foundation-National Institutes of Health workshop. Research funding opportunities are described as posted on the NIH Guide to Grants and Contracts (see http://www.nih.gov/grants/guide).

For the past six years, the NASA Science Education and Public Outreach (E/PO) Forums have supported the NASA Science Mission Directorate (SMD) and its E/PO community by enhancing the coherency and efficiency of SMD-funded E/PO programs. The Forums have fostered collaboration and partnerships between scientists with content expertise and educators with pedagogy expertise. As part of this work, in collaboration with the AAS Division of Planetary Sciences, we have interviewed SMD scientists, and more recently engineers, to understand their needs, barriers, attitudes, and understanding of education and outreach work. Respondents told us that they needed additional resources and professional development to support their work in education and outreach, including information about how to get started, ways to improve their communication, and strategies and activities for their teaching and outreach. In response, the Forums have developed and made available a suite of tools to support scientists and engineers in their E/PO efforts. These include "getting started" guides, "tips and tricks" for engaging in E/PO, vetted lists of classroom and outreach activities, and resources for college classrooms. NASA Wavelength (http://nasawavelength.org/), an online repository of SMD funded activities that have been reviewed by both educators and scientists for quality and accuracy, provides a searchable database of resources for teaching as well as ready-made lists by topic and education level, including lists for introductory college classrooms. Additionally, we have also supported scientists at professional conferences through organizing oral and poster sessions, networking activities, E/PO helpdesks, professional development workshops, and support for students and early careers scientists.

Clapp, Brian R.; Ramsey, Patrick R.; Wirzburger, John H.; Smith, Daniel C.; VanArsadall, John C.

2008-01-01

Following gyro failures in April 2001 and April 2003, HST Pointing Control System engineers designed reduced-gyro control laws to extend the spacecraft science mission. The Two-Gyro Science (TGS) and One-Gyro Science (OGS) control laws were designed and implemented using magnetometers, star trackers, and Fine Guidance Sensors in succession to control vehicle rate about the missing gyro axes. Both TGS and OGS have demonstrated on-orbit pointing stability of 7 milli-arcseconds or less, which depends upon the guide star magnitude used by the Fine Guidance Sensor. This paper describes the design, implementation, and on-orbit performance of the TGS and OGS control law fine-pointing modes using Fixed Head Star Trackers and Fine Guidance Sensors, after successfully achieving coarse-pointing control using magnetometers.

Undergraduate Students as Climate Communicators

NASA Astrophysics Data System (ADS)

Sharif, H. O.; Joseph, J.; Mullendore, G. L.

2012-12-01

The University of Texas at San Antonio (UTSA), San Antonio College (SAC), and the University of North Dakota (UND) are partnering with NASA to provide underrepresented undergraduates from UTSA, SAC, and other community colleges climate-related research and education experiences. The program aims to develop a robust response to climate change by providing K-16 climate change education; enhance the effectiveness of K-16 education particularly in engineering and other STEM disciplines by use of new instructional technologies; increase the enrollment in engineering programs and the number of engineering degrees awarded by showing engineering's usefulness in relation to the much-discussed contemporary issue of climate change; increase persistence in STEM degrees by providing student research opportunities; and increase the ethnic diversity of those receiving engineering degrees and help ensure an ethnically diverse response to climate change. Students will have the opportunity to participate in guided research experiences aligned with NASA Science Plan objectives for climate and Earth system science and the educational objectives of the three institutions. An integral part of the learning process will include training in modern media technology (webcasts), and in using this technology to communicate the information on climate change to others, especially high school students, culminating in production of a webcast about investigating aspects of climate change using NASA data. Content developed is leveraged by NASA Earth observation data and NASA Earth system models and tools. Several departments are involved in the educational program.

Physical Chemistry of Nanomedicine: Understanding the Complex Behaviors of Nanoparticles in Vivo

NASA Astrophysics Data System (ADS)

Lane, Lucas A.; Qian, Ximei; Smith, Andrew M.; Nie, Shuming

2015-04-01

Nanomedicine is an interdisciplinary field of research at the interface of science, engineering, and medicine, with broad clinical applications ranging from molecular imaging to medical diagnostics, targeted therapy, and image-guided surgery. Despite major advances during the past 20 years, there are still major fundamental and technical barriers that need to be understood and overcome. In particular, the complex behaviors of nanoparticles under physiological conditions are poorly understood, and detailed kinetic and thermodynamic principles are still not available to guide the rational design and development of nanoparticle agents. Here we discuss the interactions of nanoparticles with proteins, cells, tissues, and organs from a quantitative physical chemistry point of view. We also discuss insights and strategies on how to minimize nonspecific protein binding, how to design multistage and activatable nanostructures for improved drug delivery, and how to use the enhanced permeability and retention effect to deliver imaging agents for image-guided cancer surgery.

Inductively guided circuits for ultracold dressed atoms

PubMed Central

Sinuco-León, German A.; Burrows, Kathryn A.; Arnold, Aidan S.; Garraway, Barry M.

2014-01-01

Recent progress in optics, atomic physics and material science has paved the way to study quantum effects in ultracold atomic alkali gases confined to non-trivial geometries. Multiply connected traps for cold atoms can be prepared by combining inhomogeneous distributions of DC and radio-frequency electromagnetic fields with optical fields that require complex systems for frequency control and stabilization. Here we propose a flexible and robust scheme that creates closed quasi-one-dimensional guides for ultracold atoms through the ‘dressing’ of hyperfine sublevels of the atomic ground state, where the dressing field is spatially modulated by inductive effects over a micro-engineered conducting loop. Remarkably, for commonly used atomic species (for example, 7Li and 87Rb), the guide operation relies entirely on controlling static and low-frequency fields in the regimes of radio-frequency and microwave frequencies. This novel trapping scheme can be implemented with current technology for micro-fabrication and electronic control. PMID:25348163

Human Systems Integration (HSI) Practitioner's Guide

NASA Technical Reports Server (NTRS)

Zumbado, Jennifer Rochlis

2015-01-01

The NASA/SP-2015-3709, Human Systems Integration (HSI) Practitioner's Guide, also known as the "HSIPG," provides a tool for implementing HSI activities within the NASA systems engineering framework. The HSIPG is written to aid the HSI practitioner engaged in a program or project (P/P), and serves as a knowledge base to allow the practitioner to step into an HSI lead or team member role for NASA missions. Additionally, this HSIPG is written to address the role of HSI in the P/P management and systems engineering communities and aid their understanding of the value added by incorporating good HSI practices into their programs and projects. Through helping to build a community of knowledgeable HSI practitioners, this document also hopes to build advocacy across the Agency for establishing strong, consistent HSI policies and practices. Human Systems Integration (HSI) has been successfully adopted (and adapted) by several federal agencies-most notably the U.S. Department of Defense (DoD) and the Nuclear Regulatory Commission (NRC)-as a methodology for reducing system life cycle costs (LCCs). These cost savings manifest themselves due to reductions in required numbers of personnel, the practice of human-centered design, decreased reliance on specialized skills for operations, shortened training time, efficient logistics and maintenance, and fewer safety-related risks and mishaps due to unintended human/system interactions. The HSI process for NASA establishes how cost savings and mission success can be realized through systems engineering. Every program or project has unique attributes. This HSIPG is not intended to provide one-size-fits-all recommendations for HSI implementation. Rather, HSI processes should be tailored to the size, scope, and goals of individual situations. The instructions and processes identified here are best used as a starting point for implementing human-centered system concepts and designs across programs and projects of varying types, including manned and unmanned, human spaceflight, aviation, robotics, and environmental science missions. The practitioner using this guide should have expertise in Systems Engineering or other disciplines involved in producing systems with anticipated human interactions. (See section 1.6 of this guide for further discussion on HSI discipline domains.) The HSIPG provides an "HSI layer" to the NASA Systems Engineering Engine (SEE), detailed in NASA Procedural Requirement (NPR) 7123.1B, NASA Systems Engineering Processes and Requirements, and further explained in NASA/SP-2007-6105, Systems Engineering Handbook (see HSIPG Table 2.2-1, NASA Documents with HSI Content, for specific references and document versions).

Nuclear Engine System Simulation (NESS). Volume 1: Program user's guide

1993-03-01

A Nuclear Thermal Propulsion (NTP) engine system design analysis tool is required to support current and future Space Exploration Initiative (SEI) propulsion and vehicle design studies. Currently available NTP engine design models are those developed during the NERVA program in the 1960's and early 1970's and are highly unique to that design or are modifications of current liquid propulsion system design models. To date, NTP engine-based liquid design models lack integrated design of key NTP engine design features in the areas of reactor, shielding, multi-propellant capability, and multi-redundant pump feed fuel systems. Additionally, since the SEI effort is in the initial development stage, a robust, verified NTP analysis design tool could be of great use to the community. This effort developed an NTP engine system design analysis program (tool), known as the Nuclear Engine System Simulation (NESS) program, to support ongoing and future engine system and stage design study efforts. In this effort, Science Applications International Corporation's (SAIC) NTP version of the Expanded Liquid Engine Simulation (ELES) program was modified extensively to include Westinghouse Electric Corporation's near-term solid-core reactor design model. The ELES program has extensive capability to conduct preliminary system design analysis of liquid rocket systems and vehicles. The program is modular in nature and is versatile in terms of modeling state-of-the-art component and system options as discussed. The Westinghouse reactor design model, which was integrated in the NESS program, is based on the near-term solid-core ENABLER NTP reactor design concept. This program is now capable of accurately modeling (characterizing) a complete near-term solid-core NTP engine system in great detail, for a number of design options, in an efficient manner. The following discussion summarizes the overall analysis methodology, key assumptions, and capabilities associated with the NESS presents an example problem, and compares the results to related NTP engine system designs. Initial installation instructions and program disks are in Volume 2 of the NESS Program User's Guide.

Rising against a gathering storm: a biopolitical analysis of citizenship in STEM policy

NASA Astrophysics Data System (ADS)

Hoeg, Darren; Bencze, Larry

2017-12-01

Science, technology, engineering and mathematics (STEM) is a form of education seen by many governments and educators as a preparation of the types of students needed for the future. STEM education is being developed in many countries without the support of official policy, such as is the case in Canada. In the United States, the National Science Foundation (NSF), and a private non-profit organisation, Achieve Inc.™, have been enlisted to develop policy to guide the development on STEM nationally. Due to its influence in global politics and economy, many countries, including Canada, are interested in how the United States is preparing its citizens for the future through STEM education. In this paper we present a critical discourse analysis on STEM policy from the United States as a basis to discuss: biopolitics in science education; notions of citizenship in contemporary school education and science education; and citizenship and STEM education.

Writing-to-learn in undergraduate science education: a community-based, conceptually driven approach.

PubMed

Reynolds, Julie A; Thaiss, Christopher; Katkin, Wendy; Thompson, Robert J

2012-01-01

Despite substantial evidence that writing can be an effective tool to promote student learning and engagement, writing-to-learn (WTL) practices are still not widely implemented in science, technology, engineering, and mathematics (STEM) disciplines, particularly at research universities. Two major deterrents to progress are the lack of a community of science faculty committed to undertaking and applying the necessary pedagogical research, and the absence of a conceptual framework to systematically guide study designs and integrate findings. To address these issues, we undertook an initiative, supported by the National Science Foundation and sponsored by the Reinvention Center, to build a community of WTL/STEM educators who would undertake a heuristic review of the literature and formulate a conceptual framework. In addition to generating a searchable database of empirically validated and promising WTL practices, our work lays the foundation for multi-university empirical studies of the effectiveness of WTL practices in advancing student learning and engagement.

Liang, Huakang; Zhang, Shoujian; Su, Yikun

2018-03-29

Recently, construction safety management (CSM) practices and systems have become important topics for stakeholders to take care of human resources. However, few studies have attempted to map the global research on CSM. A comprehensive bibliometric review was conducted in this study based on multiple methods. In total, 1172 CSM-related papers from the Web of Science Core Collection database were examined. The analyses focused on publication year, country-institute, publication source, author and research topics. The results indicated that the USA, China, Australia and the UK took leading positions in CSM research. Two branches of journals were identified, namely the branch of engineering science and that of safety science and social science. Additionally, seven themes together with 28 specific topics were detected to allow researchers to track the main structure and temporal evolution of CSM research. Finally, the main research trends and potential research directions were discussed to guide the future research.

Integration of Research Into Grade Nine-Graduate Level Curricula

Bonner, J.; Callicott, K.; Page, C.

Research on the Kolb Learning Cycle, engineering education, and recent cognitive learning research indicates that learning occurs through knowledge application. Moreover, experts in a given discipline will differ from novices with regard to their ability to transfer their knowledge by application to new contexts. We have developed a suite of educational opportunities to bridge the gap between research and the classroom, with activities spanning the educational spectrum from high school through graduate school. One mechanism for transferring of research into undergraduate/graduate curricula is through our National Science Foundation (NSF) funded Combined Research-Curriculum Development (CRCD) project ("Environmental Informatics in Coastal Margins"). This project modifies engineering curricula to provide the nation with the next generation of engineers who can utilize the latest environmental modeling tools. The project revises/creates three undergraduate courses forming the environmental informatics (EI) track of the civil engineering curriculum and two graduate courses integrating GIS and environmental measurements. Curriculum development efforts are guided by an expert team drawn from nearby campuses and both regional and national industry, and includes an expert in assessing the pedagogical value of the curriculum and developing suitable metrics to evaluate student learning experiences. Another NSF-funded project integrating research into an undergraduate educational setting is our Research Experience for Undergraduates (REU) project ("Undergraduate Research in Biodiversity and Ecological Processes in Fluctuating Environments"). Research includes overlapping topics in environmental engineering and life sciences. The summer research experience provides students an opportunity to integrate engineering and life science technologies and to the study of ecological processes associated with biodiversity and environmental quality. Students orally present their project and submit in-depth papers. Over twenty publications/proceedings papers have been generated thus far. A third project involves our collaborations with the ITS Center ("Information Technology in Science Center for Teaching and Learning") on the A&M campus. As an investment in "project team growing", the Center is collaborating with us to collect data on implementation of an engineering science and math enhancement module in Hearne Independent School District. The specific activity involves a CRCD engineering class and an educational psychology undergraduate class. The engineering students give group presentations, where each presentation addresses a scenario that focuses on an environmental topic presented in the class. The students present the technical material to the education students who serve as a non-technical lay audience, emulating a city council, for example. The education students adapt the material for presentation to high school students, working with mentor teachers to enhance content, relevance and hands on experience while learning to apply teaching pedagogy.

A turbofan gas turbine engine includes a forward fan section with a row of fan rotor blades, a core engine, and a fan bypass duct downstream of the forward fan section and radially outwardly of the core engine. The forward fan section has only a single stage of variable fan guide vanes which are variable fan outlet guide vanes downstream of the forward fan rotor blades. An exemplary embodiment of the engine includes an afterburner downstream of the fan bypass duct between the core engine and an exhaust nozzle. The variable fan outlet guide vanes are operable to pivot from a nominal OGV position at take-off to an open OGV position at a high flight Mach Number which may be in a range of between about 2.5-4+. Struts extend radially across a radially inwardly curved portion of a flowpath of the engine between the forward fan section and the core engine.

Targeting CD8+ T-cell tolerance for cancer immunotherapy.

2014-01-01

In the final issue of Science in 2013, the American Association of Science recognized progress in the field of cancer immunotherapy as the 'Breakthrough of the Year.' The achievements were actually twofold, owing to the early success of genetically engineered chimeric antigen receptors (CAR) and to the mounting clinical triumphs achieved with checkpoint blockade antibodies. While fundamentally very different, the common thread of these independent strategies is the ability to prevent or overcome mechanisms of CD8(+) T-cell tolerance for improved tumor immunity. Here we discuss how circumventing T-cell tolerance has provided experimental insights that have guided the field of clinical cancer immunotherapy to a place where real breakthroughs can finally be claimed.

The rapid increase of available scientific knowledge is largely due to the introduction of novel research strategies. The application of these strategies, both in fundamental and in translational scientific research, leads to bursts of technological innovations. In order to fulfill the justified public request for sustainability of technological innovations that contribute to the shaping of the future, increasing attention should be given to science-based technology and policy assessment. These requests are illustrated by benefit/risk evaluations of relevance for the use of genetic engineering as an efficient and effective research strategy. Expected benefits of a responsibly planned introduction of GM crops are outlined as a prospective example for the guiding theme "Biotechnology for sustainability of human society".

The research summarized here has the goal of developing a fundamental understanding of how catalysts work. These materials are demonstrably essential to our daily life, from the cars we drive to the clothes we wear. Our Center advances the science behind how we prepare, analyze, and describe catalysts. This has been identified by one of the documents guiding Federal research objectives (Directing Matter and Energy: Five Challenges for Science and the Imagination): “Major challenges in heterogeneous catalysis are to more clearly define the nature of the active sites, to engineer at the molecular level catalysis with designed properties in threemore » dimensions, and to create new catalysts for new transformations.” This directly addresses this objective.« less

Process oriented guided inquiry learning (POGIL®) marginally effects student achievement measures but substantially increases the odds of passing a course.

PubMed

Walker, Lindsey; Warfa, Abdi-Rizak M

2017-01-01

While the inquiry approach to science teaching has been widely recommended as an epistemic mechanism to promote deep content understanding, there is also increased expectation that process and other transferable skills should be integral part of science pedagogy. To test the hypothesis that coupling process skills to content teaching impacts academic success measures, we meta-analyzed twenty-one studies (n = 21) involving 7876 students that compared Process Oriented Guided Inquiry Learning (POGIL), a pedagogy that provides opportunities for improving process skills during content learning through guided-inquiry activities, to standard lecture conditions. Based on conventional measures of class performance, POGIL had a small effect on achievement outcomes (effect size = 0.29, [95% CI = 0.15-0.43]) but substantially improved the odds of passing a class (odds ratio = 2.02, [95% CI: 1.45-2.83]). That is, participants in the POGIL pedagogy had higher odds of passing a course and roughly performed 0.3 standard deviations higher on achievement measures than participants in standard lectures. In relative risk terms, POGIL reduced the risk of failing a course by 38%. These findings suggest providing opportunities to improve process skills during class instruction does not inhibit content learning but enhances conventional success measures. We compare these findings with those of recent large meta-analysis that examined the effects of global active learning methods on achievement outcomes and course failure rates in science, technology, engineering, and mathematics (STEM) fields.

Visible Light Laser Guidestar Experiments (ViLLaGEs) is a new Micro-Electro Mechanical Systems (MEMS) based visible-wavelength adaptive optics (AO) testbed on the Nickel 1-meter telescope at Lick Observatory. Closed loop Natural Guide Star (NGS) experiments were successfully carried out during engineering during the fall of 2007. This is a major evolutionary step, signaling the movement of AO technologies into visible light with a MEMS mirror. With on-sky Strehls in I-band of greater than 20% during second light tests, the science possibilities have become evident. Described here is the advanced engineering used in the design and construction of the ViLLaGEs system, comparing it to the LickAO infrared system, and a discussion of Nickel dome infrastructural improvements necessary for this system. A significant portion of the engineering discussion revolves around the sizable effort that went towards eliminating flexure. Then, we detail upgrades to ViLLaGEs to make it a facility class instrument. These upgrades will focus on Nyquist sampling the diffraction limited point spread function during open loop operations, motorization and automation for technician level alignments, adding dithering capabilities and changes for near infrared science.

NASA Technical Reports Server (NTRS)

Caton, Randall H.; Pinelli, Thomas E.; Giersch, Christopher E.; Holmes, Ellen B.; Lambert, Matthew A.

2005-01-01

NASA CONNECT is an Emmy-award-winning series of instructional (distance learning) programs for grades 6-8. Produced by the NASA Center for Distance Learning, the nine programs in the 2003-2004 NASA CONNECT series are research-, inquiry-, standards-, teacher-, and technology-based and include a 30-minute program, an educator guide containing a hands-on activity, and a web-based component. The 1,500 randomly selected NASA CONNECT registered users were invited to complete an electronic (self-reported) survey that employed a 5-point Likert-type scale. Regarding NASA CONNECT, respondents reported that the programs (1) enhance the teaching of mathematics, science, and technology (4.53); (2) are aligned with the national mathematics, science, and technology standards (4.52); (3) raise student awareness of careers requiring mathematics, science, and technology (4.48); (4) demonstrate the application of mathematics, science, and technology (4.47); and (5) present women and minorities performing challenging engineering and science tasks (4.50).

Earth Science Education Plan: Inspire the Next Generation of Earth Explorers

NASA Technical Reports Server (NTRS)

2004-01-01

The Education Enterprise Strategy, the expanding knowledge of how people learn, and the community-wide interest in revolutionizing Earth and space science education have guided us in developing this plan for Earth science education. This document builds on the success of the first plan for Earth science education published in 1996; it aligns with the new framework set forth in the NASA Education Enterprise Strategy; it recognizes the new educational opportunities resulting from research programs and flight missions; and it builds on the accomplishments th'at the Earth Science Enterprise has made over the last decade in studying Earth as a system. This document embodies comprehensive, practicable plans for inspiring our children; providing educators with the tools they need to teach science, technology, engineering, and mathematics (STEM); and improving our citizens' scientific literacy. This plan describes an approach to systematically sharing knowledge; developing the most effective mechanisms to achieve tangible, lasting results; and working collaboratively to catalyze action at a scale great enough to ensure impact nationally and internationally. This document will evolve and be periodically reviewed in partnership with the Earth science education community.

Integration of Engineering Education by High School Teachers to Meet Standards in the Physics Classroom

NASA Astrophysics Data System (ADS)

Kersten, Jennifer Anna

In recent years there has been increasing interest in engineering education at the K-12 level, which has resulted in states adopting engineering standards as a part of their academic science standards. From a national perspective, the basis for research into engineering education at the K-12 level is the belief that it is of benefit to student learning, including to "improve student learning and achievement in science and mathematics; increase awareness of engineering and the work of engineers; boost youth interest in pursuing engineering as a career; and increase the technological literacy of all students" (National Research Council, 2009a, p. 1). The above has led to a need to understand how teachers are currently implementing engineering education in their classrooms. High school physics teachers have a history of implementing engineering design projects in their classrooms, thus providing an appropriate setting to look for evidence of quality engineering education at the high school level. Understanding the characteristics of quality engineering integration can inform curricular and professional development efforts for teachers asked to implement engineering in their classrooms. Thus, the question that guided this study is: How, and to what extent, do physics teachers represent quality engineering in a physics unit focused on engineering? A case study research design was implemented for this project. Three high school physics teachers were participants in this study focused on the integration of engineering education into the physics classroom. The data collected included observations, interviews, and classroom documents that were analyzed using the Framework for Quality K-12 Engineering Education (Moore, Glancy et al., 2013). The results provided information about the areas of the K-12 engineering framework addressed during these engineering design projects, and detailed the quality of these lesson components. The results indicate that all of the design projects contained components of the indicators central to engineering education, although with varied degrees of success. In addition, each design project contained aspects important to the development of students' understanding of engineering and that promote important professional skills used by engineers. The implications of this work are discussed at the teacher, school, professional development, and policy levels.

Teaching Rocks and Minerals in the Context of Dynamic Earth Systems and Interactions: Using the Three Dimensions of the Next Generation Science Standards as an Organizing Framework to Engage Learners in Teacher Preparation Courses

NASA Astrophysics Data System (ADS)

Brady, M. E.; Nelson, F.

2014-12-01

The Next Generation Science Standards (NGSS) call for a shift from science learning as a fixed body of decontextualized facts toward a deliberate integration of three dimensions that transcend instructional level: 1) Disciplinary Core Ideas, 2) Crosscutting concepts, and 3) Science & Engineering Practices. This new approach to K-12 science education requires a dedicated effort to address teacher preparation in ESS. Here, we present an instructional model that explicitly integrates the three dimensions of the NGSS as an organizing framework in large-enrollment, undergraduate introductory geoscience courses targeted toward future teachers. This curriculum development is part of a campus-wide collaboration among science, engineering, and education faculty to enhance science teacher preparation. This approach reflects NGSS conceptual shifts and promotes a learner-centered environment where students regularly engage with each other and course material as part of the course: 1) In terms of content, Earth systems and interactions, are emphasized; rocks and minerals are discussed in the context of their use to understand and predict changes over Earth's past, present, and future; and engineering and technology are incorporated into discussions of mediating human impacts on Earth systems. 2) Cross-cutting concepts, such as cycles and flows, are explicitly referenced throughout the course to promote connections between and application of prior knowledge and new information or situations. 3) Guided by explicit prompts for partner discussions in class, students regularly engage in scientific practices, such as arguing by evidence and constructing an explanation. We will provide examples of student learning assessment, including in-class responses pre- and post- partner discussions, short written reflections, and cumulative projects. Ongoing evaluation of this instructional approach will include pre- and post- Geoscience Concept Inventory responses.

Engineering behaviour change in an epidemic: the epistemology of NIH-funded HIV prevention science.

PubMed

Green, Adam; Kolar, Kat

2015-05-01

Social scientific and public health literature on National Institutes of Health-funded HIV behavioural prevention science often assumes that this body of work has a strong biomedical epistemological orientation. We explore this assumption by conducting a systematic content analysis of all NIH-funded HIV behavioural prevention grants for men who have sex with men between 1989 and 2012. We find that while intervention research strongly favours a biomedical orientation, research into the antecedents of HIV risk practices favours a sociological, interpretive and structural orientation. Thus, with respect to NIH-funded HIV prevention science, there exists a major disjunct in the guiding epistemological orientations of how scientists understand HIV risk, on the one hand, and how they engineer behaviour change in behavioural interventions, on the other. Building on the extant literature, we suggest that the cause of this disjunct is probably attributable not to an NIH-wide positivist orientation, but to the specific standards of evidence used to adjudicate HIV intervention grant awards, including randomised controlled trials and other quantitative measures of intervention efficacy. © 2015 The Authors.

Guide to solar reference spectra and irradiance models

NASA Astrophysics Data System (ADS)

Tobiska, W. Kent

The international standard for determining solar irradiances was published by the International Standards Organization (ISO) in May 2007. The document, ISO 21348 Space Environment (natural and artificial) - Process for determining solar irradiances, describes the process for representing solar irradiances. We report on the next progression of standards work, i.e., the development of a guide that identifies solar reference spectra and irradiance models for use in engineering design or scientific research. This document will be produced as an AIAA Guideline and ISO Technical Report. It will describe the content of the reference spectra and models, uncertainties and limitations, technical basis, data bases from which the reference spectra and models are formed, publication references, and sources of computer code for reference spectra and solar irradiance models, including those which provide spectrally-resolved lines as well as solar indices and proxies and which are generally recognized in the solar sciences. The document is intended to assist aircraft and space vehicle designers and developers, heliophysicists, geophysicists, aeronomers, meteorologists, and climatologists in understanding available models, comparing sources of data, and interpreting engineering and scientific results based on different solar reference spectra and irradiance models.

User engineering: A new look at system engineering

NASA Technical Reports Server (NTRS)

Mclaughlin, Larry L.

1987-01-01

User Engineering is a new System Engineering perspective responsible for defining and maintaining the user view of the system. Its elements are a process to guide the project and customer, a multidisciplinary team including hard and soft sciences, rapid prototyping tools to build user interfaces quickly and modify them frequently at low cost, and a prototyping center for involving users and designers in an iterative way. The main consideration is reducing the risk that the end user will not or cannot effectively use the system. The process begins with user analysis to produce cognitive and work style models, and task analysis to produce user work functions and scenarios. These become major drivers of the human computer interface design which is presented and reviewed as an interactive prototype by users. Feedback is rapid and productive, and user effectiveness can be measured and observed before the system is built and fielded. Requirements are derived via the prototype and baselined early to serve as an input to the architecture and software design.

Designing and Evaluating a Climate Change Course for Upper-Division Engineers and Scientists

2002-12-01

AOSS 300, GLOBAL ENVIRONMENTAL IMPACT OF TECHNOLOGICAL CHANGE, was created to provide a mechanism for scientific exploration of the unexpected global environmental side effects of technological innovation with emphasis on issues of the atmosphere and oceans. The course is specifically designed to contribute to the desired Accreditation Board for Engineering and Technology (ABET) outcomes that engineering and science graduates possess "the broad education necessary to understand the impact of solutions in a global and societal context." To facilitate this new course a new suite of coupled Flash/PHP/MySQL tools have been created that allow personalization of the students' learning space and interaction with faculty. Using these tools students are challenged to actively participate in the construction of knowledge through development of on-line portfolios that influence course content. This paper reports on lessons learned in the first semester that will guide further course development.

Receptor control in mesenchymal stem cell engineering

Dalby, Matthew J.; García, Andrés J.; Salmeron-Sanchez, Manuel

2018-03-01

Materials science offers a powerful tool to control mesenchymal stem cell (MSC) growth and differentiation into functional phenotypes. A complex interplay between the extracellular matrix and growth factors guides MSC phenotypes in vivo. In this Review, we discuss materials-based bioengineering approaches to direct MSC fate in vitro and in vivo, mimicking cell-matrix-growth factor crosstalk. We first scrutinize MSC-matrix interactions and how the properties of a material can be tailored to support MSC growth and differentiation in vitro, with an emphasis on MSC self-renewal mechanisms. We then highlight important growth factor signalling pathways and investigate various materials-based strategies for growth factor presentation and delivery. Integrin-growth factor crosstalk in the context of MSC engineering is introduced, and bioinspired material designs with the potential to control the MSC niche phenotype are considered. Finally, we summarize important milestones on the road to MSC engineering for regenerative medicine.

Chen, Yi-Bu; Chattopadhyay, Ansuman; Bergen, Phillip; Gadd, Cynthia; Tannery, Nancy

2007-01-01

To bridge the gap between the rising information needs of biological and medical researchers and the rapidly growing number of online bioinformatics resources, we have created the Online Bioinformatics Resources Collection (OBRC) at the Health Sciences Library System (HSLS) at the University of Pittsburgh. The OBRC, containing 1542 major online bioinformatics databases and software tools, was constructed using the HSLS content management system built on the Zope Web application server. To enhance the output of search results, we further implemented the Vivísimo Clustering Engine, which automatically organizes the search results into categories created dynamically based on the textual information of the retrieved records. As the largest online collection of its kind and the only one with advanced search results clustering, OBRC is aimed at becoming a one-stop guided information gateway to the major bioinformatics databases and software tools on the Web. OBRC is available at the University of Pittsburgh's HSLS Web site (http://www.hsls.pitt.edu/guides/genetics/obrc).

2012-05-01

We present initial in-lab and on-sky results of a natural guide star adaptive optics instrument, KAPAO-Alpha, being deployed on Pomona College’s 1-meter telescope at Table Mountain Observatory. The instrument is an engineering prototype designed to help us identify and solve design and integration issues before building KAPAO, a low-cost, dual-band, natural guide star AO system currently in active development and scheduled for first light in 2013. The Alpha system operates at visible wavelengths, employs Shack-Hartmann wavefront sensing, and is assembled entirely from commercially available components that include: off-the-shelf optics, a 140-actuator BMC deformable mirror, a high speed SciMeasure Lil’ Joe camera, and an EMCCD for science image acquisition. Wavefront reconstruction operating at 1-kHz speeds is handled with a consumer-grade computer running custom software adopted from the Robo-AO project. The assembly and integration of the Alpha instrument has been undertaken as a Pomona College undergraduate thesis. As part of the larger KAPAO project, it is supported by the National Science Foundation under Grant No. 0960343.

Targeting CD8+ T-cell tolerance for cancer immunotherapy

PubMed Central

Jackson, Stephanie R; Yuan, Jinyun; Teague, Ryan M

2014-01-01

In the final issue of Science in 2013, the American Association of Science recognized progress in the field of cancer immunotherapy as the ‘Breakthrough of the Year.’ The achievements were actually twofold, owing to the early success of genetically engineered chimeric antigen receptors (CAR) and to the mounting clinical triumphs achieved with checkpoint blockade antibodies. While fundamentally very different, the common thread of these independent strategies is the ability to prevent or overcome mechanisms of CD8+ T-cell tolerance for improved tumor immunity. Here we discuss how circumventing T-cell tolerance has provided experimental insights that have guided the field of clinical cancer immunotherapy to a place where real breakthroughs can finally be claimed.

Watson, Michael D.; Farrington, Phillip A.

2016-01-01

The NASA Systems Engineering Research Consortium was formed at the end of 2010 to study the approaches to producing elegant systems on a consistent basis. This has been a transformative study looking at the engineering and organizational basis of systems engineering. The consortium has engaged in a variety of research topics to determine the path to elegant systems. In the second year of the consortium, a systems engineering framework emerged which structured the approach to systems engineering and guided our research. This led in the third year to set of systems engineering postulates that the consortium is continuing to refine. The consortium has conducted several research projects that have contributed significantly to the understanding of systems engineering. The consortium has surveyed the application of the NASA 17 systems engineering processes, explored the physics and statistics of systems integration, and considered organizational aspects of systems engineering discipline integration. The systems integration methods have included system exergy analysis, Akaike Information Criteria (AIC), State Variable Analysis, Multidisciplinary Coupling Analysis (MCA), Multidisciplinary Design Optimization (MDO), System Cost Modelling, System Robustness, and Value Modelling. Organizational studies have included the variability of processes in change evaluations, margin management within the organization, information theory of board structures, social categorization of unintended consequences, and initial looks at applying cognitive science to systems engineering. Consortium members have also studied the bidirectional influence of policy and law with systems engineering.

The NASA Astrophysics Science Education and Public Outreach Forum (SEPOF) coordinates the work of NASA Science Mission Directorate (SMD) Astrophysics EPO projects and their teams to bring cutting-edge discoveries of NASA missions to the introductory astronomy college classroom. The Astrophysics Forum assists scientist and educator involvement in SMD E/PO (uniquely poised to foster collaboration between scientists with content expertise and educators with pedagogy expertise) and makes SMD E/PO resources and expertise accessible to the science and education communities. We present three new opportunities for college instructors to bring the latest NASA discoveries in Astrophysics into their classrooms.To address the expressed needs of the higher education community, the Astrophysics Forum collaborated with the Astrophysics E/PO community, researchers, and Astronomy 101 instructors to place individual science discoveries and learning resources into context for higher education audiences. Among these resources are two Resource Guides on the topics of cosmology and exoplanets, each including a variety of accessible sources.The Astrophysics Forum also coordinates the development of the Astro 101 slide set series--5 to 7-slide presentations on new discoveries from NASA Astrophysics missions relevant to topics in introductory astronomy courses. These sets enable Astronomy 101 instructors to include new discoveries not yet in their textbooks into the broader context of the course: http://www.astrosociety.org/education/astronomy-resource-guides/.The Astrophysics Forum also coordinated the development of 12 monthly Universe Discovery Guides, each featuring a theme and a representative object well-placed for viewing, with an accompanying interpretive story, strategies for conveying the topics, and supporting NASA-approved education activities and background information from a spectrum of NASA missions and programs: http://nightsky.jpl.nasa.gov/news-display.cfm?News_ID=611.These resources help enhance the Science, Technology, Engineering, and Mathematics (STEM) experiences of undergraduates.

Teacher Research Programs = Increased Student Achievement

NASA Astrophysics Data System (ADS)

Dubner, J.

2011-12-01

Columbia University's Summer Research Program for Science Teachers (SRP), founded in 1990, is one of the largest, best known university professional development programs for science teachers in the U.S. For eight weeks in each of two consecutive summers, teachers participate as a member of a research team, led by a member of Columbia University's research faculty. In addition to the laboratory experience, all teachers meet weekly during the summer for a series of pedagogical activities to assist them in transferring the experience to their classrooms. The primary goal of the program is to provide K-12 science teachers with opportunities to work at the cutting edge of science and engineering, and thus to revitalize their teaching and help them to appreciate the use of inquiry-based methods in their classroom instruction. The secondary goals of the program are to give the pre-college teacher the ability to guide their students toward careers in science and engineering, to develop new teaching strategies, and to foster long-term scholarly collaborations. The last is especially important as it leads to a model of the teacher as active in science yet committed to the pre-college classroom. Since its inception, SRP has focused on an objective assessment of the program's impact on attitudes and instructional practices of participating teachers, on the performance of these teachers in their mentors' laboratories, and most importantly, on the impact of their participation in the program has on student interest and performance in science.

Revisiting software specification and design for large astronomy projects

NASA Astrophysics Data System (ADS)

Wiant, Scott; Berukoff, Steven

2016-07-01

The separation of science and engineering in the delivery of software systems overlooks the true nature of the problem being solved and the organization that will solve it. Use of a systems engineering approach to managing the requirements flow between these two groups as between a customer and contractor has been used with varying degrees of success by well-known entities such as the U.S. Department of Defense. However, treating science as the customer and engineering as the contractor fosters unfavorable consequences that can be avoided and opportunities that are missed. For example, the "problem" being solved is only partially specified through the requirements generation process since it focuses on detailed specification guiding the parties to a technical solution. Equally important is the portion of the problem that will be solved through the definition of processes and staff interacting through them. This interchange between people and processes is often underrepresented and under appreciated. By concentrating on the full problem and collaborating on a strategy for its solution a science-implementing organization can realize the benefits of driving towards common goals (not just requirements) and a cohesive solution to the entire problem. The initial phase of any project when well executed is often the most difficult yet most critical and thus it is essential to employ a methodology that reinforces collaboration and leverages the full suite of capabilities within the team. This paper describes an integrated approach to specifying the needs induced by a problem and the design of its solution.

How to implement the Science Fair Self-Help Development Program in schools

DOE Office of Scientific and Technical Information (OSTI.GOV)

Menicucci, D.

1994-01-01

This manual is intended to act as a working guide for setting up a Science Fair Volunteer Support Committee at your school. The Science Fair Volunteer Support Committee, or SFVSC, is the key component of the Science Fair Self-Help program, which was developed by Sandia National Laboratories and is designed to support a school`s science activities. The SFVSC is a team of parents and community volunteers who work in concert with a school`s teaching staff to assist and manage all areas of a school Science and Engineering Fair. The main advantage of creating such a committee is that it freesmore » the science teachers from the organizational aspects of the fair and lets them concentrate on their job of teaching science. This manual is based on information gained through a Self-Help Development pilot program that was developed by Sandia National Laboratories during the 1991--92 school year at three Albuquerque, NM, middle schools. The manual describes the techniques that were successful in the pilot program and discusses how these techniques might be implemented in other schools. This manual also discusses problems that may be encountered, including suggestions for how they might be resolved.« less

Technology Readiness Level Assessment Process as Applied to NASA Earth Science Missions

NASA Technical Reports Server (NTRS)

Leete, Stephen J.; Romero, Raul A.; Dempsey, James A.; Carey, John P.; Cline, Helmut P.; Lively, Carey F.

2015-01-01

Technology assessments of fourteen science instruments were conducted within NASA using the NASA Technology Readiness Level (TRL) Metric. The instruments were part of three NASA Earth Science Decadal Survey missions in pre-formulation. The Earth Systematic Missions Program (ESMP) Systems Engineering Working Group (SEWG), composed of members of three NASA Centers, provided a newly modified electronic workbook to be completed, with instructions. Each instrument development team performed an internal assessment of its technology status, prepared an overview of its instrument, and completed the workbook with the results of its assessment. A team from the ESMP SEWG met with each instrument team and provided feedback. The instrument teams then reported through the Program Scientist for their respective missions to NASA's Earth Science Division (ESD) on technology readiness, taking the SEWG input into account. The instruments were found to have a range of TRL from 4 to 7. Lessons Learned are presented; however, due to the competition-sensitive nature of the assessments, the results for specific missions are not presented. The assessments were generally successful, and produced useful results for the agency. The SEWG team identified a number of potential improvements to the process. Particular focus was on ensuring traceability to guiding NASA documents, including the NASA Systems Engineering Handbook. The TRL Workbook has been substantially modified, and the revised workbook is described.

Noesis: Ontology based Scoped Search Engine and Resource Aggregator for Atmospheric Science

NASA Astrophysics Data System (ADS)

Ramachandran, R.; Movva, S.; Li, X.; Cherukuri, P.; Graves, S.

2006-12-01

The goal for search engines is to return results that are both accurate and complete. The search engines should find only what you really want and find everything you really want. Search engines (even meta search engines) lack semantics. The basis for search is simply based on string matching between the user's query term and the resource database and the semantics associated with the search string is not captured. For example, if an atmospheric scientist is searching for "pressure" related web resources, most search engines return inaccurate results such as web resources related to blood pressure. In this presentation Noesis, which is a meta-search engine and a resource aggregator that uses domain ontologies to provide scoped search capabilities will be described. Noesis uses domain ontologies to help the user scope the search query to ensure that the search results are both accurate and complete. The domain ontologies guide the user to refine their search query and thereby reduce the user's burden of experimenting with different search strings. Semantics are captured by refining the query terms to cover synonyms, specializations, generalizations and related concepts. Noesis also serves as a resource aggregator. It categorizes the search results from different online resources such as education materials, publications, datasets, web search engines that might be of interest to the user.

Writing-to-Learn in Undergraduate Science Education: A Community-Based, Conceptually Driven Approach

PubMed Central

Reynolds, Julie A.; Thaiss, Christopher; Katkin, Wendy; Thompson, Robert J.

2012-01-01

Despite substantial evidence that writing can be an effective tool to promote student learning and engagement, writing-to-learn (WTL) practices are still not widely implemented in science, technology, engineering, and mathematics (STEM) disciplines, particularly at research universities. Two major deterrents to progress are the lack of a community of science faculty committed to undertaking and applying the necessary pedagogical research, and the absence of a conceptual framework to systematically guide study designs and integrate findings. To address these issues, we undertook an initiative, supported by the National Science Foundation and sponsored by the Reinvention Center, to build a community of WTL/STEM educators who would undertake a heuristic review of the literature and formulate a conceptual framework. In addition to generating a searchable database of empirically validated and promising WTL practices, our work lays the foundation for multi-university empirical studies of the effectiveness of WTL practices in advancing student learning and engagement.

To achieve an environment less dependent on the flow of paper, automated techniques of data storage and retrieval must be utilized. The prototype under development seeks to demonstrate the ability of a knowledge-based, hypertext computer system. This prototype is concerned with the logical links between two primary NASA support documents, the Science Requirements Document (SRD) and the Engineering Requirements Document (ERD). Once developed, the final system should have the ability to guide a principal investigator through the documentation process in a more timely and efficient manner, while supplying more accurate information to the NASA payload developer.

Standing at the crossroads: Identity and recognition of the Applied Science Technologist in British Columbia

NASA Astrophysics Data System (ADS)

Roemer, Thomas

Modern technical education in British Columbia has been affected by two societal trends: in industry, engineering technology evolved as a discipline to bridge the increasing chasm between the process-oriented skill sets of tradespersons/technicians, and the declarative knowledge focus of engineering; in education, the provincial college and institute system was created to address the need for a new post-secondary credential situated between trades certificates and university degrees. The Applied Science Technologist arguably forms the intersection of these two concepts. Almost forty years after its inception, it is timely to ask if the original model has matured into a distinct occupational category in industry, education, and in the public mind. The thesis proposes three environments, the Formative, Market and Public Domain, respectively. Interviews, surveys and personal experience afforded insights into the dynamics of these domains with respect to a fledgling occupational category, while the socio-philosophical concepts of culture, habitus and social imaginary provide the tools to interpret the findings. The thesis postulates that an emerging occupational category will not only challenge existing cultures and habitus, but that over time it will influence the imaginaries of each domain and society as a whole. Ultimately, the occupational category will be truly successful only when the general public is able to distinguish it from related disciplines. Charles Taylor's writings on multiculturalism are used to discuss identity and recognition of the Applied Science Technologist in each domain while Pierre Bourdieu's perspectives on the existence of habitus and self-proliferating elites form the framework to examine the relationships between technologists and engineers. Taylor's theory of multiple concurrent social imaginaries guides the comparison of divergent expectations among academic, career and vocational instructors at British Columbia's colleges. The thesis concludes with recommendations for the sustainability of the Applied Science Technologist as distinct occupational category.

Understanding women's choices to enroll in engineering: A case study

NASA Astrophysics Data System (ADS)

Young, Eileen

The underrepresentation of women in science, technology, engineering and mathematics (STEM) college programs is a troublesome local, national and global phenomenon. The topic of this doctoral thesis specifically focused on the underrepresentation of women in the field of engineering and more specifically on the factors that women may perceive as chiefly motivating them to choose engineering as a college major. By not choosing to major in engineering, women forego intellectual opportunities and the financial rewards that engineering careers can provide. Their absence means that the field of engineering also suffers from the lack of contributions from a diverse workforce. Women who graduated from a specific community college's engineering program in the United States were the focus of this qualitative study. Grounded in achievement motivation theory, and in particular expectancy-value theory of academic and career choice, this research was guided by two questions: How do women perceive their academic self-efficacies and expectations for success as influencing their decisions to enroll in engineering? How do women perceive their subjective task values as influencing their decisions to enroll in engineering? This single, holistic case study with one main unit of analysis incorporated a written questionnaire, individual interviews and a focus group meeting as the three instruments used to collect data. The qualitative data, cyclically coded, shed light on the complex mechanisms of academic and career choice.

Development of a NASA Integrated Technical Workforce Career Development Model Entitled Requisite Occupation Competencies and Knowledge -- the ROCK

NASA Technical Reports Server (NTRS)

Menrad, Robert J.; Larson, Wiley J.

2008-01-01

This paper shares the findings of NASA's Integrated Learning and Development Program (ILDP) in its effort to reinvigorate the HANDS-ON practice of space systems engineering and project/program management through focused coursework, training opportunities, on-the job learning and special assignments. Prior to March 2005, NASA responsibility for technical workforce development (the program/project manager, systems engineering, discipline engineering, discipline engineering and associated communities) was executed by two parallel organizations. In March 2005 these organizations merged. The resulting program-ILDP-was chartered to implement an integrated competency-based development model capable of enhancing NASA's technical workforce performance as they face the complex challenges of Earth science, space science, aeronautics and human spaceflight missions. Results developed in collaboration with NASA Field Centers are reported on. This work led to definition of the agency's first integrated technical workforce development model known as the Requisite Occupation Competence and Knowledge (the ROCK). Critical processes and products are presented including: 'validation' techniques to guide model development, the Design-A-CUrriculuM (DACUM) process, and creation of the agency's first systems engineering body-of-knowledge. Findings were validated via nine focus groups from industry and government, validated with over 17 space-related organizations, at an estimated cost exceeding $300,000 (US). Masters-level programs and training programs have evolved to address the needs of these practitioner communities based upon these results. The ROCK reintroduced rigor and depth to the practitioner's development in these critical disciplines enabling their ability to take mission concepts from imagination to reality.

Experimental investigation of in-cylinder air flow to optimize number of helical guide vanes to enhance DI diesel engine performance using mamey sapote biodiesel

NASA Astrophysics Data System (ADS)

Kumar, A. Raj; Janardhana Raju, G.; Hemachandra Reddy, K.

2018-03-01

The current research work investigates the influence of helical guide vanes in to the intake runner of a D.I diesel engine operating by the high viscous Mamey Sapote biodiesel to enhance in-cylinder suction air flow features. Helical guide vanes of different number of vanes are produced from 3D printing and placed in the intake manifold to examine the air flow characteristics. Four different helical guide vane devices namely 3, 4, 5 and 6 vanes of the same dimensions are tested in a D.I diesel engine operating with Mamey Sapote biodiesel blend. As per the experimental results of engine performance and emission characteristics, it is found that 5 vanes helical guide vane swirl device exhibited in addition number of increased improvements such as the brake power and bake thermal efficiency by 2.4% and 8.63% respectively and the HC, NOx, Carbon monoxide and, Smoke densities are reduced by 15.62%, 4.23%, 14.27% and 9.6% at peak load operating conditions as collate with normal engine at the same load. Hence this investigation concluded that Helical Guide Vane Devices successfully enhanced the in-cylinder air flow to improve better addition of Mamey Sapote biodiesel with air leading in better performance of the engine than without vanes.

Engineers and Active Responsibility.

PubMed

Pesch, Udo

2015-08-01

Knowing that technologies are inherently value-laden and systemically interwoven with society, the question is how individual engineers can take up the challenge of accepting the responsibility for their work? This paper will argue that engineers have no institutional structure at the level of society that allows them to recognize, reflect upon, and actively integrate the value-laden character of their designs. Instead, engineers have to tap on the different institutional realms of market, science, and state, making their work a 'hybrid' activity combining elements from the different institutional realms. To deal with this institutional hybridity, engineers develop routines and heuristics in their professional network, which do not allow societal values to be expressed in a satisfactory manner. To allow forms of 'active' responsibility, there have to be so-called 'accountability forums' that guide moral reflections of individual actors. The paper will subsequently look at the methodologies of value-sensitive design (VSD) and constructive technology assessment (CTA) and explore whether and how these methodologies allow engineers to integrate societal values into the design technological artifacts and systems. As VSD and CTA are methodologies that look at the process of technological design, whereas the focus of this paper is on the designer, they can only be used indirectly, namely as frameworks which help to identify the contours of a framework for active responsibility of engineers.

Development of CRISPR/Cas9 mediated virus resistance in agriculturally important crops.

PubMed

Khatodia, Surender; Bhatotia, Kirti; Tuteja, Narendra

2017-05-04

Clustered regulatory interspaced short palindromic repeats (CRISPR)/CRISPR associated nuclease 9 (Cas9) system of targeted genome editing has already revolutionized the plant science research. This is a RNA guided programmable endonuclease based system composed of 2 components, the Cas9 nuclease and an engineered guide RNA targeting any DNA sequence of the form N20-NGG for novel genome editing applications. The CRISPR/Cas9 technology of targeted genome editing has been recently applied for imparting virus resistance in plants. The robustness, wide adaptability, and easy engineering of this system has proved its potential as an antiviral tool for plants. Novel DNA free genome editing by using the preassembled Cas9/gRNA ribonucleoprotein complex for development of virus resistance in any plant species have been prospected for the future. Also, in this review we have discussed the reports of CRISPR/Cas9 mediated virus resistance strategy against geminiviruses by targeting the viral genome and transgene free strategy against RNA viruses by targeting the host plant factors. In conclusion, CRISPR/Cas9 technology will provide a more durable and broad spectrum viral resistance in agriculturally important crops which will eventually lead to public acceptance and commercialization in the near future.

Mathematically precocious and female: Self-efficacy and STEM course choices among high achieving middle grade students

NASA Astrophysics Data System (ADS)

Burt, Stacey M.

The problem addressed in this project is the lack of mathematically gifted females choosing to pursue advanced science, technology, engineering, and mathematics (STEM) courses in secondary education due to deficiencies in self-efficacy. The purpose of this project was to study the effects of a child-guided robotics program as it relates to the self-efficacy of mathematically gifted 6th grade female students and their future course choices in the advanced STEM content areas. This mixed-model study utilized a STEM attitude survey, artifacts, interviews, field notes, and standardized tests as measurement tools. Significance was found between genders in the treatment group for the standardized science scores, indicating closure in the achievement gap. Research suggests that STEM enrichment is beneficial for mathematically gifted females.

In 1994, the Clinton Administration issued a report, 'Science in the National Interest', which identified new national science goals. Two of the five goals are related to science communications: produce the finest scientists and engineers for the 21st century, and raise scientific and technological literacy of all Americans. In addition to the guidance and goals set forth by the Administration, NASA has been mandated by Congress under the 1958 Space Act to 'provide for the widest practicable and appropriate dissemination concerning its activities and the results thereof'. In addition to addressing eight Goals and Plans which resulted from a January 1994 meeting between NASA and members of the broader scientific, education, and communications community on the Public Communication of NASA's Science, the Science Communications Working Group (SCWG) took a comprehensive look at the way the Agency communicates its science to ensure that any changes the Agency made were long-term improvements. The SCWG developed a Science Communications Strategy for NASA and a plan to implement the Strategy. This report outlines a strategy from which effective science communications programs can be developed and implemented across the agency. Guiding principles and strategic themes for the strategy are provided, with numerous recommendations for improvement discussed within the respective themes of leadership, coordination, integration, participation, leveraging, and evaluation.

"Water in the Solar System" is an out-of-school time (OST) science education activity for middle school students that was developed as part of the Planetary Learning that Advances the Nexus of Engineering, Technology, and Science (PLANETS) project. The PLANETS project was selected in support of the NASA Science Mission Directorate's Science Education Cooperative Agreement Notice, with the goal of developing and disseminating OST curriculum and related professional development modules that integrate planetary science, technology, and engineering. "Water in the Solar System" is a science activity that addresses the abundance and availability of water in the solar system. The activity consists of three exercises based on the following guiding questions: 1) How much water is there on the Earth? 2) Where can you find water in the solar system? and 3) What properties affect whether or not water can be used by astronauts? The three exercises involve a scaling relationship demonstration about the abundance of useable water on Earth, a card game to explore where water is found in the solar system, and a hands-on exercise to investigate pH and salinity. Through these activities students learn that although there is a lot of water on Earth, most of it is not in a form that is accessible for humans to use. They also learn that most water in the solar system is actually farther from the sun, and that properties such as salinity and pH affect whether water can be used by humans. In addition to content for students, the activity includes background information for educators, and links to in-depth descriptions of the science content. "Water in the Solar System" was developed through collaboration between subject matter experts at the USGS Astrogeology Science Center, and curriculum and professional development experts in the Center for Science Teaching and Learning at Northern Arizona University. Here we describe our process of curriculum development, education objectives of "Water in the Solar System" and lessons learned.

Science Outside the Lab: Helping Graduate Students in Science and Engineering Understand the Complexities of Science Policy.

PubMed

Bernstein, Michael J; Reifschneider, Kiera; Bennett, Ira; Wetmore, Jameson M

2017-06-01

Helping scientists and engineers challenge received assumptions about how science, engineering, and society relate is a critical cornerstone for macroethics education. Scientific and engineering research are frequently framed as first steps of a value-free linear model that inexorably leads to societal benefit. Social studies of science and assessments of scientific and engineering research speak to the need for a more critical approach to the noble intentions underlying these assumptions. "Science Outside the Lab" is a program designed to help early-career scientists and engineers understand the complexities of science and engineering policy. Assessment of the program entailed a pre-, post-, and 1 year follow up survey to gauge student perspectives on relationships between science and society, as well as a pre-post concept map exercise to elicit student conceptualizations of science policy. Students leave Science Outside the Lab with greater humility about the role of scientific expertise in science and engineering policy; greater skepticism toward linear notions of scientific advances benefiting society; a deeper, more nuanced understanding of the actors involved in shaping science policy; and a continued appreciation of the contributions of science and engineering to society. The study presents an efficacious program that helps scientists and engineers make inroads into macroethical debates, reframe the ways in which they think about values of science and engineering in society, and more thoughtfully engage with critical mediators of science and society relationships: policy makers and policy processes.

Avoid, Control, Succumb, or Balance: Engineering Students' Approaches to a Wicked Sustainability Problem

NASA Astrophysics Data System (ADS)

Lönngren, Johanna; Ingerman, Åke; Svanström, Magdalena

2017-08-01

Wicked sustainability problems (WSPs) are an important and particularly challenging type of problem. Science and engineering education can play an important role in preparing students to deal with such problems, but current educational practice may not adequately prepare students to do so. We address this gap by providing insights related to students' abilities to address WSPs. Specifically, we aim to (I) describe key constituents of engineering students' approaches to a WSP, (II) evaluate these approaches in relation to the normative context of education for sustainable development (ESD), and (III) identify relevant aspects of learning related to WSPs. Aim I is addressed through a phenomenographic study, while aims II and III are addressed by relating the results to research literature about human problem solving, sustainable development, and ESD. We describe four qualitatively different ways of approaching a specific WSP, as the outcome of the phenomenographic study: A. Simplify and avoid, B. Divide and control, C. Isolate and succumb, and D. Integrate and balance. We identify approach D as the most appropriate approach in the context of ESD, while A and C are not. On this basis, we identify three learning objectives related to students' abilities to address WSPs: learn to use a fully integrative approach, distinguish WSPs from tame and well-structured problems, and understand and consider the normative context of SD. Finally, we provide recommendations for how these learning objectives can be used to guide the design of science and engineering educational activities.

Re-engineering of Bacterial Luciferase; For New Aspects of Bioluminescence.

PubMed

Kim, Da-Som; Choi, Jeong-Ran; Ko, Jeong-Ae; Kim, Kangmin

2018-01-01

Bacterial luminescence is the end-product of biochemical reactions catalyzed by the luciferase enzyme. Nowadays, this fascinating phenomenon has been widely used as reporter and/or sensors to detect a variety of biological and environmental processes. The enhancement or diversification of the luciferase activities will increase the versatility of bacterial luminescence. Here, to establish the strategy for luciferase engineering, we summarized the identity and relevant roles of key amino acid residues modulating luciferase in Vibrio harveyi, a model luminous bacterium. The current opinions on crystal structures and the critical amino acid residues involved in the substrate binding sites and unstructured loop have been delineated. Based on these, the potential target residues and/or parameters for enzyme engineering were also suggested in limited scale. In conclusion, even though the accurate knowledge on the bacterial luciferase is yet to be reported, the structure-guided site-directed mutagenesis approaches targeting the regulatory amino acids will provide a useful platform to re-engineer the bacterial luciferase in the future.

The Impact of Design-Based STEM Integration Curricula on Student Achievement in Engineering, Science, and Mathematics

NASA Astrophysics Data System (ADS)

Selcen Guzey, S.; Harwell, Michael; Moreno, Mario; Peralta, Yadira; Moore, Tamara J.

2017-04-01

The new science education reform documents call for integration of engineering into K-12 science classes. Engineering design and practices are new to most science teachers, meaning that implementing effective engineering instruction is likely to be challenging. This quasi-experimental study explored the influence of teacher-developed, engineering design-based science curriculum units on learning and achievement among grade 4-8 students of different races, gender, special education status, and limited English proficiency (LEP) status. Treatment and control students ( n = 4450) completed pretest and posttest assessments in science, engineering, and mathematics as well as a state-mandated mathematics test. Single-level regression results for science outcomes favored the treatment for one science assessment (physical science, heat transfer), but multilevel analyses showed no significant treatment effect. We also found that engineering integration had different effects across race and gender and that teacher gender can reduce or exacerbate the gap in engineering achievement for student subgroups depending on the outcome. Other teacher factors such as the quality of engineering-focused science units and engineering instruction were predictive of student achievement in engineering. Implications for practice are discussed.

Generation of a conditional analog-sensitive kinase in human cells using CRISPR/Cas9-mediated genome engineering.

PubMed

Moyer, Tyler C; Holland, Andrew J

2015-01-01

The ability to rapidly and specifically modify the genome of mammalian cells has been a long-term goal of biomedical researchers. Recently, the clustered, regularly interspaced, short palindromic repeats (CRISPR)/Cas9 system from bacteria has been exploited for genome engineering in human cells. The CRISPR system directs the RNA-guided Cas9 nuclease to a specific genomic locus to induce a DNA double-strand break that may be subsequently repaired by homology-directed repair using an exogenous DNA repair template. Here we describe a protocol using CRISPR/Cas9 to achieve bi-allelic insertion of a point mutation in human cells. Using this method, homozygous clonal cell lines can be constructed in 5-6 weeks. This method can also be adapted to insert larger DNA elements, such as fluorescent proteins and degrons, at defined genomic locations. CRISPR/Cas9 genome engineering offers exciting applications in both basic science and translational research. Copyright © 2015 Elsevier Inc. All rights reserved.

2018-01-01

Genome editing mediated by Clustered Regularly Interspaced Palindromic Repeats (CRISPR) and its associated proteins (Cas) has recently been considered to be used as efficient, rapid and site-specific tool in the modification of endogenous genes in biomedically important cell types and whole organisms. It has become a predictable and precise method of choice for genome engineering by specifying a 20-nt targeting sequence within its guide RNA. Firstly, this review aims to describe the biology of CRISPR system. Next, the applications of CRISPR-Cas9 in various ways, such as efficient generation of a wide variety of biomedically important cellular models as well as those of animals, modifying epigenomes, conducting genome-wide screens, gene therapy, labelling specific genomic loci in living cells, metabolic engineering of yeast and bacteria and endogenous gene expression regulation by an altered version of this system were reviewed.

Science Teachers' Misconceptions in Science and Engineering Distinctions: Reflections on Modern Research Examples

NASA Astrophysics Data System (ADS)

Antink-Meyer, Allison; Meyer, Daniel Z.

2016-10-01

The aim of this exploratory study was to learn about the misconceptions that may arise for elementary and high school science teachers in their reflections on science and engineering practice. Using readings and videos of real science and engineering work, teachers' reflections were used to uncover the underpinnings of their understandings. This knowledge ultimately provides information about supporting professional development (PD) for science teachers' knowledge of engineering. Six science teachers (two elementary and four high school teachers) participated in the study as part of an online PD experience. Cunningham and Carlsen's (Journal of Science Teacher Education 25:197-210, 2014) relative emphases of science and engineering practices were used to frame the design of PD activities and the analyses of teachers' views. Analyses suggest misconceptions within the eight practices of science and engineering from the US Next Generation Science Standards in four areas. These are that: (1) the nature of the practices in both science and engineering research is determined by the long-term implications of the research regardless of the nature of the immediate work, (2) engineering and science are hierarchical, (3) creativity is inappropriate, and (4) research outcomes cannot be processes. We discuss the nature of these understandings among participants and the implications for engineering education PD for science teachers.

On intergenerational equity and its clash with intragenerational equity and on the need for policies to guide the regulation of disposal of wastes and other activities posing very long-term risks

DOE Office of Scientific and Technical Information (OSTI.GOV)

Okrent, D.

1999-10-01

This article begins with some history of the derivation of 40 CFR Part 191, the US Environmental Protection Agency (EPA) standard that governs the geologic disposal of spent nuclear fuel and high-level and transuranic radioactive wastes. This is followed by criticisms of the standard that were made by a Sub-Committee of the EPA Science Advisory Board, by the staff of the US Nuclear Regulatory Commission, and by a penal of the National Academies of Science and Engineering. The large disparity in the EPA approaches to regulation of disposal of radioactive wastes and disposal of hazardous, long-lived, nonradioactive chemical waste ismore » illustrated. An examination of the intertwined matters of intergenerational equity and the discounting of future health effects follows, together with a discussion of the conflict between intergenerational equity and intragenerational equity. Finally, issues related to assumptions in the regulations concerning the future state of society and the biosphere are treated, as is the absence of any national philosophy or guiding policy for how to deal with societal activities that pose very long-term risks.« less

Engaging Parents and Pupils in Astronomy

NASA Astrophysics Data System (ADS)

Stevenson, Rod

2016-04-01

"The British National Space Centre partnership has recognised for some time that Space and Astronomy are particularly attractive subjects for school students and that including these in the science curriculum can have a positive effect on student interest in science. Drivers are that the number of young people studying science and engineering subjects at A-level and beyond is declining; young people should have an understanding of the importance of science and technology to the world around them; and that UK space industry (including technology, engineering, space science, Earth observation science) must renew itself." BRINGING SPACE INTO SCHOOL Professor Martin Barstow, University of Leicester Published by PPARC on behalf of the British National Space Centre Partnership October 2005 "It has become more and more difficult to persuade young people to follow a career in STEM (Science, Technology, Engineering & Mathematics) subjects. Across the EU, the number of graduates in STEM subjects has dropped from 24.3% in 2002 to 22.6% in 2011" (Source EUSTAT) It was Martin Barstow's report in 2005 that started my attempt to interest people in Science and Technology, At Ormiston Victory Academy (OVA) for the past two years, we have embarked on a program to enthuse pupils to study science related subject through the medium of Astronomy. We teach Edexcel GCSE Astronomy to a joint parent and pupil group. They study together and at the end of the course, both take the GCSE examination. The idea is that the pupils see that science is important to their parents and that a very practical facet of science is also fun. Astronomy is a multidisciplinary course bringing together elements of Science, Maths, Technology, Geography and History. It is hoped that the enthusiasm shown by the pupils will spill over into the mainstream subjects including maths. The parents get an idea of the work and level of knowledge required by their children to complete a GCSE level subject. They also report back that they find it a confidence raising activity that they can still learn new information. It is also an opportunity to take Science out into the community as an outreach event. Spaceschool.org.uk is a company that takes space and rocket themed activities out to primary and secondary schools in East Anglia along with youth and adult groups such as Rainbow, Brownies, Guides, Cubs, Scouts and Aeronautical and Engineering interest groups. It also provides advice to TV, film and museums in the area. Future plans include launching a mobile digital planetarium scheme to interested parties in East Anglia to replace the current holes in a dome system available for only three months of the year at present. East Anglia is often viewed as behind the times in terms of infrastructure and outlook by the rest of the UK. I want to show that we can have cutting edge resources along with all of the UK.

Becoming an engineer: Doctoral women's perspectives on identity and learning in the culture of engineering

NASA Astrophysics Data System (ADS)

Wood, Shaunda L.

Women face many obstacles in their academic careers but there is a gap in the research with regards to their perceptions of science and engineering education and how non/participation in the culture of engineering affects their identities. Moreover, little research has been conducted with female Ph.D. students especially with regard to the reasons they have continued their studies, and their level of satisfaction with their career and lives. This study was guided by the sociocultural approach and theories of learning and identity. Methodologically, the design adopted is a naturalistic qualitative inquiry using two open-ended interviews with participant verification after the first interview. The life history narratives (Mishler, 1999) obtained from the seven doctoral electrical and mechanical women engineers, at various stages in their programs, were the primary source of data. By examining the path of becoming a doctoral woman engineer, this study makes the educational experiences of women intelligible to the general public as well as policy makers. It gives voice to the women engineers whose perspectives are rarely heard in academic settings or mainstream society. The findings of the study lend insight to the importance and necessity of more inclusive engineering education, incorporating not only women's studies courses into the curriculum but anti-racism education as well as including the perspective of 'Other' people of difference. Moreover, multi-perspective approaches to increasing enrolment and retention of women in engineering were more effective and in keeping with addressing notions of 'difference' in engineering populations.

An Engineering Technology Skills Framework that Reflects Workforce Needs on Maui and the Big Island of Hawai'i

Seagroves, S.; Hunter, L.

2010-12-01

The Akamai Workforce Initiative (AWI) is an interdisciplinary effort to improve science/engineering education in the state of Hawai'i, and to train a diverse population of local students in the skills needed for a high-tech economy. In 2009, the AWI undertook a survey of industry partners on Maui and the Big Island of Hawai'i to develop an engineering technology skills framework that will guide curriculum development at the U. of Hawai'i - Maui (formerly Maui Community College). This engineering skills framework builds directly on past engineering-education developments within the Center for Adaptive Optics Professional Development Program, and draws on curriculum development frameworks and engineering skills standards from the literature. Coupling that previous work with reviews of past Akamai Internship projects and information from previous conversations with the local high-tech community led to a structured-interview format where engineers and managers could contribute meaningful commentary to this framework. By incorporating these local high-tech companies' needs for entry-level engineers and technicians, a skills framework emerges that is unique and illuminating. Two surprising features arise in this framework: (1) "technician-like" skills of making existing technology work are on similar footing with "engineer-like" skills of creating new technology; in fact, both engineers and technicians at these workplaces use both sets of skills; and (2) project management skills are emphasized by employers even for entry-level positions.

The Galileoscope was developed by a team of educators, astronomers and optical engineers as one of the cornerstone projects for the International Year of Astronomy 2009 (IYA). Over 230,000 Galileoscopes have been distributed.The National Optical Astronomy Observatory (NOAO) has developed a variety of educational materials to accompany the Galileoscope. The Galileoscope Optics Guide contains a variety of experiments and demonstrations (adapted from the National Science Foundation funded Hands-On Optics program) to help students understand how a telescope focuses light and produces an image. The Teaching With Telescopes kit developed at NOAO contains a variety of materials teachers can use to teach about light and optics. The Teaching With Telescopes kit is a basis for teacher professional development. The Galileoscope Observing Guide (updated annually) contains a variety of observing tips and information on the best objects to observe with the Galileoscope.NOAO has used Galileoscopes in a wide variety of educational environments. NOAO received a grant from Science Foundation Arizona to bring the Hands-On Optics program to Boys and Girls Clubs in Arizona. All the Boys and Girls Clubs received Galileoscopes as part of the grant. Edelman Financial made a donation that allowed us to distribute 15,000 Galileoscopes to Project ASTRO sites, members of the National Earth Science Teacher’s Association and individual teachers. Science Foundation Arizona partnered with NOAO in the Arizona Galileoscope program to conduct star parties in Yuma, Flagstaff, Safford, Globe and Payson. NOAO partnered with Raytheon in the MathMovesU program to build Galileoscopes with over 2,000 students in Tucson. NOAO has used Galileoscopes in professional development workshops with teachers at meetings including the American Astronomical Society, the Astronomical Society of the Pacific, and the National Science Teachers Association.

A new biology for a new century.

PubMed

Woese, Carl R

2004-06-01

Biology today is at a crossroads. The molecular paradigm, which so successfully guided the discipline throughout most of the 20th century, is no longer a reliable guide. Its vision of biology now realized, the molecular paradigm has run its course. Biology, therefore, has a choice to make, between the comfortable path of continuing to follow molecular biology's lead or the more invigorating one of seeking a new and inspiring vision of the living world, one that addresses the major problems in biology that 20th century biology, molecular biology, could not handle and, so, avoided. The former course, though highly productive, is certain to turn biology into an engineering discipline. The latter holds the promise of making biology an even more fundamental science, one that, along with physics, probes and defines the nature of reality. This is a choice between a biology that solely does society's bidding and a biology that is society's teacher.

Practical Strategy on the Subject of “Science and Ethics” for Overcoming Hybrid Engineering Ethics Education

NASA Astrophysics Data System (ADS)

Yasui, Yoshiaki

The issue of economic globalization and JABEE (Japan Accreditation Board for Engineering Education) mean that education on engineering ethics has now become increasingly important for science-engineering students who will become the next generation of engineers. This is clearly indicated when engineers are made professionally responsible for various unfortunate accidents that happen during daily life in society. Learning hybrid engineering ethics is an essential part of the education of the humanities and sciences. This paper treats the contents for the subject of “Science and Ethics” drawing on several years of practice and the fruits of studying science and engineering ethics at the faculty of science-engineering in university. This paper can be considered to be a practical strategy to the formation of morality.

The Effect of Guided-Inquiry Instruction on 6th Grade Turkish Students' Achievement, Science Process Skills, and Attitudes Toward Science

NASA Astrophysics Data System (ADS)

Koksal, Ela Ayse; Berberoglu, Giray

2014-01-01

The purpose of this study is to investigate the effectiveness of guided-inquiry approach in science classes over existing science and technology curriculum in developing content-based science achievement, science process skills, and attitude toward science of grade level 6 students in Turkey. Non-equivalent control group quasi-experimental design was used to investigate the treatment effect. There were 162 students in the experimental group and 142 students in the control group. Both the experimental and control group students took the Achievement Test in Reproduction, Development, and Growth in Living Things (RDGLT), Science Process Skills Test, and Attitudes Toward Science Questionnaire, as pre-test and post-test. Repeated analysis of variance design was used in analyzing the data. Both the experimental and control group students were taught in RDGLT units for 22 class hours. The results indicated the positive effect of guided-inquiry approach on the Turkish students' cognitive as well as affective characteristics. The guided inquiry enhanced the experimental group students' understandings of the science concepts as well as the inquiry skills more than the control group students. Similarly, the experimental group students improved their attitudes toward science more than the control group students as a result of treatment. The guided inquiry seems a transition between traditional teaching method and student-centred activities in the Turkish schools.

Effects of Engineering Design-Based Science on Elementary School Science Students' Engineering Identity Development across Gender and Grade

NASA Astrophysics Data System (ADS)

Capobianco, Brenda M.; Yu, Ji H.; French, Brian F.

2015-04-01

The integration of engineering concepts and practices into elementary science education has become an emerging concern for science educators and practitioners, alike. Moreover, how children, specifically preadolescents (grades 1-5), engage in engineering design-based learning activities may help science educators and researchers learn more about children's earliest identification with engineering. The purpose of this study was to examine the extent to which engineering identity differed among preadolescents across gender and grade, when exposing students to engineering design-based science learning activities. Five hundred fifty preadolescent participants completed the Engineering Identity Development Scale (EIDS), a recently developed measure with validity evidence that characterizes children's conceptions of engineering and potential career aspirations. Data analyses of variance among four factors (i.e., gender, grade, and group) indicated that elementary school students who engaged in the engineering design-based science learning activities demonstrated greater improvements on the EIDS subscales compared to those in the comparison group. Specifically, students in the lower grade levels showed substantial increases, while students in the higher grade levels showed decreases. Girls, regardless of grade level and participation in the engineering learning activities, showed higher scores in the academic subscale compared to boys. These findings suggest that the integration of engineering practices in the science classroom as early as grade one shows potential in fostering and sustaining student interest, participation, and self-concept in engineering and science.

Designing an ultrafast laser virtual laboratory using MATLAB GUIDE

NASA Astrophysics Data System (ADS)

Cambronero-López, F.; Gómez-Varela, A. I.; Bao-Varela, C.

2017-05-01

In this work we present a virtual simulator developed using the MATLAB GUIDE environment based on the numerical resolution of the nonlinear Schrödinger equation (NLS) and using the split step method for the study of the spatial-temporal propagation of nonlinear ultrashort laser pulses. This allows us to study the spatial-temporal propagation of ultrafast pulses as well as the influence of high-order spectral phases such as group delay dispersion and third-order dispersion on pulse compression in time. The NLS can describe several nonlinear effects, in particular in this paper we consider the Kerr effect, cross-polarized wave generation and cubic-quintic propagation in order to highlight the potential of this equation combined with the GUIDE environment. Graphical user interfaces are commonly used in science and engineering teaching due to their educational value, and have proven to be an effective way to engage and motivate students. Specifically, the interactive graphical interfaces presented provide the visualization of some of the most important nonlinear optics phenomena and allows users to vary the values of the main parameters involved.

Advances and Challenges In Uncertainty Quantification with Application to Climate Prediction, ICF design and Science Stockpile Stewardship

NASA Astrophysics Data System (ADS)

Klein, R.; Woodward, C. S.; Johannesson, G.; Domyancic, D.; Covey, C. C.; Lucas, D. D.

2012-12-01

Uncertainty Quantification (UQ) is a critical field within 21st century simulation science that resides at the very center of the web of emerging predictive capabilities. The science of UQ holds the promise of giving much greater meaning to the results of complex large-scale simulations, allowing for quantifying and bounding uncertainties. This powerful capability will yield new insights into scientific predictions (e.g. Climate) of great impact on both national and international arenas, allow informed decisions on the design of critical experiments (e.g. ICF capsule design, MFE, NE) in many scientific fields, and assign confidence bounds to scientifically predictable outcomes (e.g. nuclear weapons design). In this talk I will discuss a major new strategic initiative (SI) we have developed at Lawrence Livermore National Laboratory to advance the science of Uncertainty Quantification at LLNL focusing in particular on (a) the research and development of new algorithms and methodologies of UQ as applied to multi-physics multi-scale codes, (b) incorporation of these advancements into a global UQ Pipeline (i.e. a computational superstructure) that will simplify user access to sophisticated tools for UQ studies as well as act as a self-guided, self-adapting UQ engine for UQ studies on extreme computing platforms and (c) use laboratory applications as a test bed for new algorithms and methodologies. The initial SI focus has been on applications for the quantification of uncertainty associated with Climate prediction, but the validated UQ methodologies we have developed are now being fed back into Science Based Stockpile Stewardship (SSS) and ICF UQ efforts. To make advancements in several of these UQ grand challenges, I will focus in talk on the following three research areas in our Strategic Initiative: Error Estimation in multi-physics and multi-scale codes ; Tackling the "Curse of High Dimensionality"; and development of an advanced UQ Computational Pipeline to enable complete UQ workflow and analysis for ensemble runs at the extreme scale (e.g. exascale) with self-guiding adaptation in the UQ Pipeline engine. This work was performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under Contract DE-AC52-07NA27344 and was funded by the Uncertainty Quantification Strategic Initiative Laboratory Directed Research and Development Project at LLNL under project tracking code 10-SI-013 (UCRL LLNL-ABS-569112).

One more thing: Faculty response to increased emphasis on project teams in undergraduate engineering education

NASA Astrophysics Data System (ADS)

Hunter, Jane

Tenured and tenure-track faculty members at institutions of higher education, especially those at Research I institutions, are being asked to do more than ever before. With rapidly changing technology, significant decreases in public funding, the shift toward privately funded research, and the ever increasing expectations of students for an education that adequately prepares them for professional careers, engineering faculty are particularly challenged by the escalating demands on their time. In 1996, the primary accreditation organization for engineering programs (ABET) adopted new criteria that required, among other things, engineering programs to teach students to function on multidisciplinary teams and to communicate effectively. In response, most engineering programs utilize project teams as a strategy for teaching these skills. The purpose of this qualitative study of tenured and tenure track engineering faculty at a Research I institution in the southwestern United States was to explore the variety of ways in which the engineering faculty responded to the demands placed upon them as a result of the increased emphasis on project teams in undergraduate engineering education. Social role theory and organizational climate theory guided the study. Some faculty viewed project teams as an opportunity for students to learn important professional skills and to benefit from collaborative learning but many questioned the importance and feasibility of teaching teamwork skills and had concerns about taking time away from other essential fundamental material such as mathematics, basic sciences and engineering sciences. Although the administration of the College of Engineering articulated strong support for the use of project teams in undergraduate education, the prevailing climate did little to promote significant efforts related to effective utilization of project teams. Too often, faculty were unwilling to commit sufficient time or effort to make project teamwork a truly valuable learning opportunity because those efforts were not perceived to be valuable and were rarely rewarded. Few formal professional development opportunities were available and few incentives were in place to encourage other informal efforts to develop the necessary skills. Those who committed significant effort to project teams were challenged by concerns about team composition, student accountability and assigning individual grades for group teamwork.

Science-based stockpile stewardship at Los Alamos National Laboratory

I would like to start by working from Vic Reis`s total quality management diagram in which he began with the strategy and then worked through the customer requirements-what the Department of Defense (DoD) is hoping for from the science-based stockpile stewardship program. Maybe our customer`s requirements will help guide some of the issues that we should be working on. ONe quick answer to {open_quotes}why have we adopted a science-based strategy{close_quotes} is that nuclear weapons are a 50-year responsibility, not just a 5-year responsibility, and stewardship without testing is a grand challenge. While we can do engineering maintenance and turn overmore » and remake a few things on the short time scale, without nuclear testing, without new weapons development, and without much of the manufacturing base that we had in the past, we need to learn better just how these weapons are actually working.« less

2017-01-01

For the past decade, the Hawaii Student / Teacher Astronomy Research program (HI STAR) at UH Manoa’s Institute for Astronomy has trained astronomy-enthusiastic high school students in research, data analysis and science presentation skills. Every summer, a selected group of 8th-to-12th-grade students attend a week-long residential astronomy "camp" in Honolulu, Hawaii. The students experience the profession of astronomy by learning scientific skills such as imaging and spectroscopy, data-reduction, and data analysis. The week culminates with presention of a research project guided by professional astronomer mentors. During the following six months, each student continues to work with a mentor to complete a research project for submission to their local science fair. From 2012 - 2015, ~80% of students completed their long-term projects. Many have performed well; in each of 2015 and 2016, 5 alumni progressed to the International Science and Engineering Fair. Here we present the current structure of HI STAR and plans for the future.

Astrobiobound! Search for Life in the Solar System: Scientists and Engineers Bringing their Challenges to K-12 Students

NASA Astrophysics Data System (ADS)

Klug Boonstra, S. L.; Swann, J.; Manfredi, L.; Zippay, A.; Boonstra, D.

2014-12-01

The Next Generation Science Standards (NGSS) brought many dynamic opportunities and capabilities to the K-12 science classroom - especially with the inclusion of engineering. Using science as a context to help students engage in the engineering practices and engineering disciplinary core ideas is an essential step to students' understanding of how science drives engineering and how engineering enables science. Real world examples and applications are critical for students to see how these disciplines are integrated. Furthermore, the interface of science and engineering raise the level of science understanding, and facilitate higher order thinking skills through relevant experiences. Astrobiobound! is designed for the NGSS (Next Generation Science Standards) and CCSS (Common Core State Standards). Students also practice and build 21st Century Skills. Astrobiobound! help students see how science and systems engineering are integrated to achieve a focused scientific goal. Students engage in the engineering design process to design a space mission which requires them to balance the return of their science data with engineering limitations such as power, mass and budget. Risk factors also play a role during this simulation and adds to the excitement and authenticity. Astrobiobound! presents the authentic first stages of NASA mission design process. This simulation mirrors the NASA process in which the science goals, type of mission, and instruments to return required data to meet mission goals are proposed within mission budget before any of the construction part of engineering can begin. NASA scientists and engineers were consulted in the development of this activity as an authentic simulation of their mission proposal process.

Programmatic Efforts Affect Retention of Women in Science and Engineering

NASA Astrophysics Data System (ADS)

Hathaway, Russel S.; Sharp, Sally; Davis, Cinda-Sue

This article presents findings from a study that investigated the impact of a women in science and engineering residence program (WISE-RP) on the retention of women in science and engineering disciplines. From a matched sample of 1,852 science and engineering students, the authors compared WISE-RP participants with male and female control students for science and engineering retention. The findings suggest a strong connection between WISE-KP participation and science retention, but not engineering retention. The results also indicate that a WISE-RP is more effective in retaining White and Asian students than underrepresented students of color. The authors highlight the importance of combining academic and personal support in a residential learning program and draw implications for retaining women т science, mathematics, and engineering disciplines.

A phenomenographic study of students' experiences with transition from pre-college engineering programs to first-year engineering

NASA Astrophysics Data System (ADS)

Salzman, Noah

Recent national dialogues on the importance of preparing more students for careers in Science, Technology, Engineering, and Mathematics has driven the development of formal and informal learning opportunities for children and adolescents to explore engineering. Despite the growth of these programs, relatively little research exists on how participation in these programs affects students who choose to pursue further study in engineering. The present study addressed this gap through an exploration of the different ways that First-Year Engineering students experience the transition from pre-college engineering to undergraduate engineering studies. Given the focus of this research on students' experiences, phenomenography was chosen to explore the phenomenon of transition from pre-college to first-year engineering at a large, public Midwestern university. This facilitated understanding the range of variation in the ways that students experienced this transition. Twenty-two students with different amounts of participation in a variety of different engineering programs were selected to be interviewed using a purposeful maximum variation sampling strategy. The interviews were guided by a semi-structured interview protocol that encouraged the participants to reflect on their pre-college engineering experiences, their experiences in First-Year Engineering, and the transition between the two domains. The interviews were analyzed using phenomenographic methods to develop an outcome space consisting of five qualitatively different but related ways of experiencing the transition from pre-college to First-Year Engineering. These categories of description included Foreclosure, Frustration, Tedium, Connection, and Engaging Others. With the exception of the first category which was characterized by a lack of passion and commitment to engineering, the remaining four categories formed a hierarchical relationship representing increasing integration in First-Year Engineering. The outcome space that emerged from this study captured a variety of positive and negative ways that the participants experienced their transitions to First-Year Engineering. Positive outcomes included increased familiarity and confidence with the material being taught in First-Year Engineering, a stronger commitment and drive to be successful in engineering, and the ability to encourage and incorporate input from others in the design process. Negative outcomes included less interest in First-Year Engineering projects, disappointment at the lack of alignment with pre-college engineering, and a struggle to connect with their peers. While not initially guided by Self-Determination Theory, the results of this study align with aspects of Self-Determination Theory, and the relationships between the results of this study and the motivational factors of competence, autonomy, and relatedness are explored. Finally, implications for First-Year and pre-college engineering instructional practices are presented, along with a plan for future work.

The purpose of this study was to identify student's conceptual change of global warming after integrated science learning based guided inquiry through conceptual metaphors. This study used a quasi-experimental with a nonequivalent control group design. The subject was students of two classes of one of MTsN Salido. Data was collected using conceptual change test (pretest and posttest), observation sheet to observe the learning processes, questionnaire sheet to identify students responses, and interview to identifyteacher'srespons of science learning with conceptual metaphors. The results showed that science learning based guided inquiry with conceptual metaphors is better than science learning without conceptual metaphors. The average of posttest experimental class was 79,40 and control class was 66,09. The student's conceptual change for two classes changed significantly byusing mann whitney U testwith P= 0,003(P less than sig. value, P< 0,05). This means that there was differenceson student's conceptual changebeetwen integrated science learning based guided inquiry with conceptual metaphors class and integrated science learning without conceptual metaphors class. The study also showed that teachers and studentsgive positive responsesto implementation of integrated science learning based guided inquiry with conceptual metaphors.

Tanamatayarat, J.; Sujarittham, T.; Wuttiprom, S.; Hefer, E.

2017-09-01

In higher education, lecturing has been found to be the most prevalent teaching format for large classes. Generally, this format tends not to result in effective learning outcomes. Therefore, to support student learning in these large lecture classes, we developed guided notes containing quotations, blank spaces, pictures, and problems. A guided note taking strategy was selected and has been used in our introductory physics course for many years. In this study, we investigated the results of implementing the guided note taking strategy to promote student learning on electrostatics. The samples were three groups of first-year students from two universities: 163 and 224 science students and 147 engineering students. All of the students were enrolled in the introductory physics course in the second semester. To assess the students’ understanding, we administered pre- and post-tests to the students by using the electrostatics test. The questions were selected from the conceptual survey of electricity and magnetism (CSEM) and some leading physics textbooks. The results of the students’ understanding were analyzed by the average normalized gains (). The value of each group was 0.61, 0.55, and 0.54, respectively. Furthermore, the students’ views on learning with the guided note taking strategy were explored by using the five-point rating scale survey. Most students perceived that the strategy helped support their active learning and engagement in the lectures.

Computational and structure guided methods can make significant contributions to the development of solutions for difficult protein engineering problems, including the optimization of next generation of engineered antibodies. In this paper, we describe a contemporary industrial antibody engineering program, based on hypothesis-driven in silico protein optimization method. The foundational concepts and methods of computational protein engineering are discussed, and an example of a computational modeling and structure-guided protein engineering workflow is provided for the design of best-in-class heterodimeric Fc with high purity and favorable biophysical properties. We present the engineering rationale as well as structural and functional characterization data on these engineered designs. Copyright © 2013 Elsevier Inc. All rights reserved.

A systems theory approach to career development: Exploring factors that affect science as a career choice

NASA Astrophysics Data System (ADS)

Liskey, Brian K.

This research project was designed to examine the factors that affect students' choice in a career. Specifically, the factors of (a) achievement, (b) interest, (c) self-efficacy, (d) perceived preparation for a career, and (e) being informed about a career will be under investigation. Of key importance to the study is how these factors can affect a student's perception about choosing a science career. A quantitative analysis of secondary data from the 2006 and 2009 Program for International Student Assessment (PISA) international assessment and attitudinal questionnaire provided data on student perceptions and aptitude in science. The sample from PISA included over 400,000 15 year-old students from 57 countries. From the 57 countries, 30 countries, comprised by Organization for Economic and Cooperative Development (OECD), were isolated for analysis. Within this group of 30, 11 were selected for comparison based on their questionnaire response to expectations for a career in science at age 30. The Institute for Educational Science's, International Data Explorer was utilized to acquire and analyze data from the 2006 and 2009 PISA international tests and questionnaires to determine significance between scaled scores and PISA indices. Variables were chosen as factors affecting student's perception on various systems outlined by the Systems Theory of Career Development (Patton & McMahon, 1997) and the Systems Theory of Career Development Framework (Patton & McMahon, 1999). Four country groups were established based on student responses to question 30a from the 2006 PISA attitudinal questionnaire, which asks what career students expected to have at age 30. The results from comparing country groups showed that countries in Group A, which showed the highest values for students expecting a career in science, also had the highest average values for achievement on the PISA science literacy assessment. Likewise, countries that had the lowest values for expecting a career in science (Group B) also had the lowest average values for achievement in science as assessed by science literacy score according to PISA. The United States (Group C) and the International Average (Group D) were both intermediate in each of the two categories. The analysis also showed an identical country group sequence from highest responses to lowest responses for the "systems" or variables of a) self-efficacy, b) preparation for a science career, and c) information about a career in science. The group sequence from high to low values was Group C, Group B, Group D, Group A. When comparing this country group sequence there appears to be a weak negative association between students in countries that expect a career in science and the values for self-efficacy, being prepared for, and informed about a career in science. The findings from this study indicate that the greatest factor affecting students' perception for expecting a career in science is high achievement in science. These results provide key insight on the Systems Theory of Career Development missing from the existing body of literature. Leaders in the fields of education and educational policy can use this information to guide practices and promote programs that will aid in higher achievement in science and engineering. This research can also be used by leaders in career counseling to advise students on appropriate career paths and prepare students for future careers in science and technology. Finally, leadership within state and federal institutions can utilize results from this study to guide future research and funding that encourages students on career pathways in the fields of Science Technology Engineering and Mathematics (STEM).

Genome Editing with CRISPR-Cas9: Can It Get Any Better?

PubMed

Haeussler, Maximilian; Concordet, Jean-Paul

2016-05-20

The CRISPR-Cas revolution is taking place in virtually all fields of life sciences. Harnessing DNA cleavage with the CRISPR-Cas9 system of Streptococcus pyogenes has proven to be extraordinarily simple and efficient, relying only on the design of a synthetic single guide RNA (sgRNA) and its co-expression with Cas9. Here, we review the progress in the design of sgRNA from the original dual RNA guide for S. pyogenes and Staphylococcus aureus Cas9 (SpCas9 and SaCas9). New assays for genome-wide identification of off-targets have provided important insights into the issue of cleavage specificity in vivo. At the same time, the on-target activity of thousands of guides has been determined. These data have led to numerous online tools that facilitate the selection of guide RNAs in target sequences. It appears that for most basic research applications, cleavage activity can be maximized and off-targets minimized by carefully choosing guide RNAs based on computational predictions. Moreover, recent studies of Cas proteins have further improved the flexibility and precision of the CRISPR-Cas toolkit for genome editing. Inspired by the crystal structure of the complex of sgRNA-SpCas9 bound to target DNA, several variants of SpCas9 have recently been engineered, either with novel protospacer adjacent motifs (PAMs) or with drastically reduced off-targets. Novel Cas9 and Cas9-like proteins called Cpf1 have also been characterized from other bacteria and will benefit from the insights obtained from SpCas9. Genome editing with CRISPR-Cas9 may also progress with better understanding and control of cellular DNA repair pathways activated after Cas9-induced DNA cleavage.

How the Discovery Channel Television Show Mythbusters Accurately Depicts Science and Engineering Culture

NASA Astrophysics Data System (ADS)

Zavrel, Erik A.

2011-04-01

High school science teachers, of course, want to motivate their students to consider studying science and engineering (S&E) in college. However, many high school students are not familiar with what science and engineering actually entail. They may know science as little more than "systematic discovery" and engineering as nothing but "math-intensive design." Without appreciation for the rich culture of science and engineering, students will be unlikely to choose such a field of study. The Discovery Channel television show Mythbusters helps remedy the lack of understanding many people, especially young people, have about S&E. Mythbusters presents a highly accurate vignette of the culture of science and engineering. Episodes of the show were analyzed for instances in which the culture of science and engineering was accurately depicted. Many resources, including several publications of the National Research Council, informed the media analysis. To encourage more high school students to pursue S&E in college, they need to be exposed to the culture of S&E. Mythbusters provides a window into the often unseen realm of science and engineering, allowing its viewers, who are disproportionately represented among the young adult age bracket, to see what it means to conduct science and engineering on a routine basis. High school science instructors should look to Mythbusters to provide insight into the culture of S&E that textbooks often have difficulty conveying to students.

Using FIRST LEGO League Robotics Competitions to Engage Middle School Students in Physics

NASA Astrophysics Data System (ADS)

Rosen, Jeffrey

2009-11-01

As the nation and world grapple with looming crises in sectors such as energy, health care and the environment, it is critical that we keep today's youth interested in careers in science, technology, engineering and math (STEM). Studies indicate that many students lose interest in the sciences by ages 10-13, when they are in grades 4-8 in the U.S. educational system. Many of the interventions to counteract this trend focus on boosting interest in STEM in secondary schools and universities. However the case can be made that the greater need is actually earlier in the education of the child. How can we work with this age group in an exciting way that will promote the study of science? Student robotics competitions might be one effective answer. Programs are currently being run around the country and the world that engage young people in the study of science through robotic competition. Many of these programs rely on mentors to guide the students through the process, which in the most effective programs includes the study of physic concepts through engineering design. During this presentation we will discuss the options for participating in programs that help the students and teachers better understand the science, specifically the physics, which underlies robotics. In particular, we will focus on the international program called FIRST LEGO League (FLL), in which students ages 9-14 are challenged every year to construct a LEGO robot that can navigate and complete a course of theme-related missions. The FLL program is currently operating in almost every state in the U.S. and relies on recruiting qualified mentors and judges who want to impact young people's interest in STEM.

The U.S. Geological Survey (USGS) serves the Nation by providing reliable scientific information and tools to build resilience in communities exposed to subduction zone earthquakes, tsunamis, landslides, and volcanic eruptions. Improving the application of USGS science to successfully reduce risk from these events relies on whole community efforts, with continuing partnerships among scientists and stakeholders, including researchers from universities, other government labs and private industry, land-use planners, engineers, policy-makers, emergency managers and responders, business owners, insurance providers, the media, and the general public.Motivated by recent technological advances and increased awareness of our growing vulnerability to subduction-zone hazards, the USGS is uniquely positioned to take a major step forward in the science it conducts and products it provides, building on its tradition of using long-term monitoring and research to develop effective products for hazard mitigation. This science plan provides a blueprint both for prioritizing USGS science activities and for delineating USGS interests and potential participation in subduction zone science supported by its partners.The activities in this plan address many USGS stakeholder needs:High-fidelity tools and user-tailored information that facilitate increasingly more targeted, neighborhood-scale decisions to mitigate risks more cost-effectively and ensure post-event operability. Such tools may include maps, tables, and simulated earthquake ground-motion records conveying shaking intensity and frequency. These facilitate the prioritization of retrofitting of vulnerable infrastructure;Information to guide local land-use and response planning to minimize development in likely hazardous zones (for example, databases, maps, and scenario documents to guide evacuation route planning in communities near volcanoes, along coastlines vulnerable to tsunamis, and built on landslide-prone terrain);New tools to assess the potential for cascading hazards, such as landslides, tsunamis, coastal changes, and flooding caused by earthquakes or volcanic eruptions;Geospatial models of permanent, widespread land- and sea-level changes that may occur in the immediate aftermath of great (M ≥8.0) subduction zone earthquakes;Strong partnerships between scientists and public safety providers for effective decision making during periods of elevated hazard and risk;Accurate forecasts of far-reaching hazards (for example, ash clouds, tsunamis) to avert catastrophes and unnecessary disruptions in air and sea transportation;Aftershock forecasts to guide decisions about when and where to re-enter, repair, or rebuild buildings and infrastructure, for all types of subduction zone earthquakes.

The 16-meter diffraction limited lunar telescope incorporates a primary mirror with 312 one-meter segments; 3 nanometer active optics surface control with laser metrology and hexapod positioners; a space frame structure with one-millimeter stability; and a hexapod mount for pointing. The design data needed to limit risk in this development can be obtained by building a smaller engineering telescope on the moon with all of the features of the 16-meter design. This paper presents a 4.33-meter engineering telescope concept developed by the Summer 1990 Student Program of the NASA/JHU Space Grant Consortium Lunar Telescope Project. The primary mirror, made up of 18 one-meter hexagonal segments, is sized to provide interesting science as well as engineering data. The optics are configured as a Ritchey-Chretien with a coude relay to the focal plane beneath the surface. The optical path is continuously monitored with 3-nanometer precision interferometrically. An active optics processor and piezoelectric actuators operate to maintain the end-to-end optical configuration established by wave front sensing using a guide star. The mirror segments, consisting of a one-centimeter thick faceplate on 30-cm deep ribs, maintain the surface figure to a few nanometers under lunar gravity and thermal environment.

A Social Responsibility Guide for Engineering Students and Professionals of all Faith Traditions: An Overview.

PubMed

Punzi, Vito L

2017-07-18

The development of the various themes of Catholic Social Teaching (CST) is based on numerous papal documents and ecclesiastical statements. While this paper provides a summary of a number of these documents, this paper focuses on two themes: the common good and care of the environment, and on three documents authored by Pope John Paul II in 1990, by Pope Benedict XVI in 2010, and by Pope Francis in 2015. By analyzing these documents from an engineer's perspective, the author proposes a model for Socially Responsible Engineering. The proposed model is intended to serve as a guide for engineering students and practicing engineers of all faith traditions and to those with no faith tradition at all who wish to incorporate CST in the daily conduct of their personal and professional lives; to provide guidance for the professional the author terms the aspiring Socially Responsible Engineer; and to offer engineers a preferred alternative to the undesirable aspects of the technocratic paradigm. While intended primarily for engineers, this document also serves as a guide for those with expertise in social justice and who, by gaining a better understanding of the thought processes of engineers, can become better mentors for engineering students and practicing engineers seeking to incorporate CST into their daily lives.

From engineering hydrology to Earth system science: milestones in the transformation of hydrologic science

NASA Astrophysics Data System (ADS)

Sivapalan, Murugesu

2018-03-01

Hydrology has undergone almost transformative changes over the past 50 years. Huge strides have been made in the transition from early empirical approaches to rigorous approaches based on the fluid mechanics of water movement on and below the land surface. However, progress has been hampered by problems posed by the presence of heterogeneity, including subsurface heterogeneity present at all scales. The inability to measure or map the heterogeneity everywhere prevented the development of balance equations and associated closure relations at the scales of interest, and has led to the virtual impasse we are presently in, in terms of development of physically based models needed for hydrologic predictions. An alternative to the mapping of heterogeneity everywhere is a new Earth system science view, which sees the heterogeneity as the end result of co-evolutionary hydrological, geomorphological, ecological, and pedological processes, each operating at a different rate, which help to shape the landscapes that we find in nature, including the heterogeneity that we do not readily see. The expectation is that instead of specifying exact details of the heterogeneity in our models, we can replace it (without loss of information) with the ecosystem function that they perform. Guided by this new Earth system science perspective, development of hydrologic science is now addressing new questions using novel holistic co-evolutionary approaches as opposed to the physical, fluid mechanics based reductionist approaches that we inherited from the recent past. In the emergent Anthropocene, the co-evolutionary view has expanded further to involve interactions and feedbacks with human-social processes as well. In this paper, I present my own perspective of key milestones in the transformation of hydrologic science from engineering hydrology to Earth system science, drawn from the work of several students and colleagues of mine, and discuss their implication for hydrologic observations, theory development, and predictions.

Corrosion chemistry closing comments: opportunities in corrosion science facilitated by operando experimental characterization combined with multi-scale computational modelling.

PubMed

Scully, John R

2015-01-01

Recent advances in characterization tools, computational capabilities, and theories have created opportunities for advancement in understanding of solid-fluid interfaces at the nanoscale in corroding metallic systems. The Faraday Discussion on Corrosion Chemistry in 2015 highlighted some of the current needs, gaps and opportunities in corrosion science. Themes were organized into several hierarchical categories that provide an organizational framework for corrosion. Opportunities to develop fundamental physical and chemical data which will enable further progress in thermodynamic and kinetic modelling of corrosion were discussed. These will enable new and better understanding of unit processes that govern corrosion at the nanoscale. Additional topics discussed included scales, films and oxides, fluid-surface and molecular-surface interactions, selected topics in corrosion science and engineering as well as corrosion control. Corrosion science and engineering topics included complex alloy dissolution, local corrosion, and modelling of specific corrosion processes that are made up of collections of temporally and spatially varying unit processes such as oxidation, ion transport, and competitive adsorption. Corrosion control and mitigation topics covered some new insights on coatings and inhibitors. Further advances in operando or in situ experimental characterization strategies at the nanoscale combined with computational modelling will enhance progress in the field, especially if coupling across length and time scales can be achieved incorporating the various phenomena encountered in corrosion. Readers are encouraged to not only to use this ad hoc organizational scheme to guide their immersion into the current opportunities in corrosion chemistry, but also to find value in the information presented in their own ways.

FY04 Engineering Technology Reports Laboratory Directed Research and Development

DOE Office of Scientific and Technical Information (OSTI.GOV)

Sharpe, R M

2005-01-27

This report summarizes the science and technology research and development efforts in Lawrence Livermore National Laboratory's Engineering Directorate for FY2004, and exemplifies Engineering's more than 50-year history of developing the technologies needed to support the Laboratory's missions. Engineering has been a partner in every major program and project at the Laboratory throughout its existence and has prepared for this role with a skilled workforce and the technical resources developed through venues like the Laboratory Directed Research and Development Program (LDRD). This accomplishment is well summarized by Engineering's mission: ''Enable program success today and ensure the Laboratory's vitality tomorrow''. Engineering's investmentmore » in technologies is carried out through two programs, the ''Tech Base'' program and the LDRD program. LDRD is the vehicle for creating those technologies and competencies that are cutting edge. These require a significant level of research or contain some unknown that needs to be fully understood. Tech Base is used to apply technologies to a Laboratory need. The term commonly used for Tech Base projects is ''reduction to practice''. Therefore, the LDRD report covered here has a strong research emphasis. Areas that are presented all fall into those needed to accomplish our mission. For FY2004, Engineering's LDRD projects were focused on mesoscale target fabrication and characterization, development of engineering computational capability, material studies and modeling, remote sensing and communications, and microtechnology and nanotechnology for national security applications. Engineering's five Centers, in partnership with the Division Leaders and Department Heads, are responsible for guiding the long-term science and technology investments for the Directorate. The Centers represent technologies that have been identified as critical for the present and future work of the Laboratory, and are chartered to develop their respective areas. Their LDRD projects are the key resources to attain this competency, and, as such, nearly all of Engineering's portfolio falls under one of the five Centers. The Centers and their Directors are: (1) Center for Computational Engineering: Robert M. Sharpe; (2) Center for Microtechnology and Nanotechnology: Raymond P. Mariella, Jr.; (3) Center for Nondestructive Characterization: Harry E. Martz, Jr.; (4) Center for Precision Engineering: Keith Carlisle; and (5) Center for Complex Distributed Systems: Gregory J.

Using the CLEAN educational resource collection for building three-dimensional lessons to teach the climate system

The impacts of climate change are a critical societal challenge of the 21st century. Educating students about the globally connected climate system is key in supporting the development of mitigation and adaptation strategies. Systems thinking is required for students to understand the complex, dynamic climate systems and the role that humans play within them. The interdisciplinary nature of climate science challenges educators, who often don't have formal training in climate science, to identify resources that are scientifically accurate before weaving them together into units that teach about the climate system. The Climate Literacy and Energy Awareness Network (CLEAN) supports this work by providing over 700 peer-reviewed, classroom-ready resources on climate and energy topics. The resource collection itself provide only limited instructional guidance, so educators need to weave the resources together to build multi-dimensional lessons that develop systems thinking skills. The Next Generation Science Standards (NGSS) science standards encourage educators to teach science in a 3-dimensional approach that trains students in systems thinking. The CLEAN project strives to help educators design NGSS-style, three-dimensional lessons about the climate system. Two approaches are currently being modeled on the CLEAN web portal. The first is described in the CLEAN NGSS "Get Started Guide" which follows a step-by-step process starting with the Disciplinary Core Idea and then interweaves the Cross-Cutting Concepts (CCC) and the Science and Engineering Practices (SEP) based on the teaching strategy chosen for the lesson or unit topic. The second model uses a climate topic as a starting place and the SEP as the guide through a four-step lesson sequence called "Earth Systems Investigations". Both models use CLEAN reviewed lessons as the core activity but provide the necessary framework for classroom implementation. Sample lessons that were developed following these two approaches are provided on the CLEAN web portal (cleanet.org).

Moses, John F.; Behnke, Jeanne; Durachka, Christopher D.

2016-01-01

At Goddard, engineers and scientists with a range of experience in science data systems are needed to employ new technologies and develop advances in capabilities for supporting new Earth and Space science research. Engineers with extensive experience in science data, software engineering and computer-information architectures are needed to lead and perform these activities. The increasing types and complexity of instrument data and emerging computer technologies coupled with the current shortage of computer engineers with backgrounds in science has led the need to develop a career path for science data systems engineers and architects.The current career path, in which undergraduate students studying various disciplines such as Computer Engineering or Physical Scientist, generally begins with serving on a development team in any of the disciplines where they can work in depth on existing Goddard data systems or serve with a specific NASA science team. There they begin to understand the data, infuse technologies, and begin to know the architectures of science data systems. From here the typical career involves peermentoring, on-the-job training or graduate level studies in analytics, computational science and applied science and mathematics. At the most senior level, engineers become subject matter experts and system architect experts, leading discipline-specific data centers and large software development projects. They are recognized as a subject matter expert in a science domain, they have project management expertise, lead standards efforts and lead international projects. A long career development remains necessary not only because of the breadth of knowledge required across physical sciences and engineering disciplines, but also because of the diversity of instrument data being developed today both by NASA and international partner agencies and because multidiscipline science and practitioner communities expect to have access to all types of observational data.This paper describes an approach to defining career-path guidance for college-bound high school and undergraduate engineering students, junior and senior engineers from various disciplines.

Immune-mediated tissue regeneration driven by a biomaterial scaffold is emerging as an innovative regenerative strategy to repair damaged tissues. We investigated how biomaterial scaffolds shape the immune microenvironment in traumatic muscle wounds to improve tissue regeneration. The scaffolds induced a pro-regenerative response, characterized by an mTOR/Rictor-dependent T helper 2 pathway that guides interleukin-4-dependent macrophage polarization, which is critical for functional muscle recovery. Manipulating the adaptive immune system using biomaterials engineering may support the development of therapies that promote both systemic and local pro-regenerative immune responses, ultimately stimulating tissue repair.

Wu, Hualong; Kamran Siddiqui, Muhammad; Zhao, Bo; Gan, Jianhou; Gao, Wei

2017-06-01

From the earlier studies in physical and chemical sciences, it is found that the physico-chemical characteristics of chemical compounds are internally connected with their molecular structures. As a theoretical basis, it provides a new way of thinking by analyzing the molecular structure of the compounds to understand their physical and chemical properties. In our article, we study the physico-chemical properties of certain molecular structures via computing the Ediz eccentric connectivity index from mathematical standpoint. The results we yielded mainly apply to the techniques of distance and degree computation of mathematical derivation, and the conclusions have guiding significance in physical engineering.

CRISPR/Cas9 advances engineering of microbial cell factories.

Jakočiūnas, Tadas; Jensen, Michael K; Keasling, Jay D

2016-03-01

One of the key drivers for successful metabolic engineering in microbes is the efficacy by which genomes can be edited. As such there are many methods to choose from when aiming to modify genomes, especially those of model organisms like yeast and bacteria. In recent years, clustered regularly interspaced palindromic repeats (CRISPR) and its associated proteins (Cas) have become the method of choice for precision genome engineering in many organisms due to their orthogonality, versatility and efficacy. Here we review the strategies adopted for implementation of RNA-guided CRISPR/Cas9 genome editing with special emphasis on their application for metabolic engineering of yeast and bacteria. Also, examples of how nuclease-deficient Cas9 has been applied for RNA-guided transcriptional regulation of target genes will be reviewed, as well as tools available for computer-aided design of guide-RNAs will be highlighted. Finally, this review will provide a perspective on the immediate challenges and opportunities foreseen by the use of CRISPR/Cas9 genome engineering and regulation in the context of metabolic engineering.

The 1995 NASA guide to graduate support

NASA Technical Reports Server (NTRS)

1994-01-01

The future of the United States is in the classrooms of America and tomorrow's scientific and technological capabilities are derived from today's investments in research. In 1980, NASA initiated the Graduate Student Researchers Program (GSRP) to cultivate additional research ties to the academic community and to support promising students pursuing advanced degrees in science and engineering. Since then, approximately 1300 students have completed the program's requirements. In 1987, the program was expanded to include the Underrepresented Minority and Disabled Focus (UMDF) Component. This program was designed to increase participation of underrepresented groups in graduate study and research and, ultimately, in space science and aerospace technology careers. Approximately 270 minority students have completed the program's requirements while making significant contributions to the nation's aerospace efforts. Continuing to expand fellowship opportunities, NASA announced the Graduate Student Fellowships in Global Change Research in 1990. Designed to support the rapid growth in the study of earth as a system, more than 250 fellowships have been awarded. And, in 1992, NASA announced opportunities in the multiagency High Performance Computing and Communications (HPCC) Program designed to accelerate the development and application of massively parallel processing. Approximately five new fellowships will be awarded yearly. This booklet will guide you in your efforts to participate in programs for graduate student support.

We describe KAPAO, our project to develop and deploy a low-cost, remote-access, natural guide star adaptive optics (AO) system for the Pomona College Table Mountain Observatory (TMO) 1-meter telescope. We use a commercially available 140-actuator BMC MEMS deformable mirror and a version of the Robo-AO control software developed by Caltech and IUCAA. We have structured our development around the rapid building and testing of a prototype system, KAPAO-Alpha, while simultaneously designing our more capable final system, KAPAO-Prime. The main differences between these systems are the prototype's reliance on off-the-shelf optics and a single visible-light science camera versus the final design's improved throughput and capabilities due to the use of custom optics and dual-band, visible and near-infrared imaging. In this paper, we present the instrument design and on-sky closed-loop testing of KAPAO-Alpha as well as our plans for KAPAO-Prime. The primarily undergraduate-education nature of our partner institutions, both public (Sonoma State University) and private (Pomona and Harvey Mudd Colleges), has enabled us to engage physics, astronomy, and engineering undergraduates in all phases of this project. This material is based upon work supported by the National Science Foundation under Grant No. 0960343.

The purpose of this research is to describe the effectiveness of guided inquiry-based learning material to improve students’ science literacy skills on solubility and solubility product concepts. This study used Research and Development (R&D) design and was implemented to the 11th graders of Muhammadiyah 4 Senior High School Surabaya in 2016/2017 academic year with one group pre-test and post-test design. The data collection techniques used were validation, observation, test, and questionnaire. The results of this research showed that the students’ science literacy skills are different after implementation of guided inquiry-based learning material. The guided inquiry-based learning material is effective to improve students’ science literacy skills on solubility and solubility product concepts by getting N-gain score with medium and high category. This improvement caused by the developed learning material such as lesson plan, student worksheet, and science literacy skill tests were categorized as valid and very valid. In addition, each of the learning phases in lesson plan has been well implemented. Therefore, it can be concluded that the guided inquiry-based learning material are effective to improve students’ science literacy skills on solubility and solubility product concepts in senior high school.

PubMed

Tate, Denise G; Pledger, Constance

2003-04-01

Advances in research on disability and rehabilitation are essential to creating equal opportunity, economic self-sufficiency, and full participation for persons with disabilities. Historically, such initiatives have focused on separate and specific areas, including neuroscience, molecular biology and genetics, gerontology, engineering and physical sciences, and social and behavioral sciences. Research on persons with disabilities should examine the broader context and trends of society that affect the total environment of persons with disabilities. This article examines the various disability paradigms across time, assessing the relative contribution of the socioecological perspective in guiding research designed to improve the lives of persons with disabilities. The authors recommend new research directions that include a focus on life span issues, biomedicine, biotechnology, the efficacy and effectiveness of current interventions, an emphasis on consumer-driven investigations within a socioecological perspective of disability, and the implications for research and practice.

Sanders, Gary H.

2008-07-01

TMT is a big science project and its scale is greater than previous ground-based optical/infrared telescope projects. This paper will describe the ideal "linear" project and how the TMT project departs from that ideal. The paper will describe the needed adaptations to successfully manage real world complexities. The progression from science requirements to a reference design, the development of a product-oriented Work Breakdown Structure (WBS) and an organization that parallels the WBS, the implementation of system engineering, requirements definition and the progression through Conceptual Design to Preliminary Design will be summarized. The development of a detailed cost estimate structured by the WBS, and the methodology of risk analysis to estimate contingency fund requirements will be summarized. Designing the project schedule defines the construction plan and, together with the cost model, provides the basis for executing the project guided by an earned value performance measurement system.

Capillary optics for radiation focusing

DOE Office of Scientific and Technical Information (OSTI.GOV)

Peurrung, A.J.; Reeder, P.L.; Bliss, M.

Capillary lens technology may ultimately bring benefits to neutron and x-ray-based science like conventional lenses with visible light. Although the technology is not yet 10 years old, these lenses have already had a significant impact in engineering, science, and medicine. Capillary lenses are advantageous when it is desirable to increase the radiation flux at a location without regard to its angular divergence. PNNL has worked to improve the technology in several ways. A single, optimally tapered capillary was manufactured, which allows intensity gains of a factor of 270 for an initially parallel, incident x-ray beam. Feasibility of constructing neutron lensesmore » using {sup 58}Ni (particularly effective at reflecting neutrons) has been explored. Three applications for capillary optics have been identified and studied: neutron telescope, Gandolphi x-ray diffractometry, and neutron radiotherapy. A brief guide is given for determining which potential applications are likely to be helped by capillary optics.« less

Optical character recognition: an illustrated guide to the frontier

Nagy, George; Nartker, Thomas A.; Rice, Stephen V.

1999-12-01

We offer a perspective on the performance of current OCR systems by illustrating and explaining actual OCR errors made by three commercial devices. After discussing briefly the character recognition abilities of humans and computers, we present illustrated examples of recognition errors. The top level of our taxonomy of the causes of errors consists of Imaging Defects, Similar Symbols, Punctuation, and Typography. The analysis of a series of 'snippets' from this perspective provides insight into the strengths and weaknesses of current systems, and perhaps a road map to future progress. The examples were drawn from the large-scale tests conducted by the authors at the Information Science Research Institute of the University of Nevada, Las Vegas. By way of conclusion, we point to possible approaches for improving the accuracy of today's systems. The talk is based on our eponymous monograph, recently published in The Kluwer International Series in Engineering and Computer Science, Kluwer Academic Publishers, 1999.

A three-year high school science research program has been taught in Woodbridge Township School District - Woodbridge, New Jersey, since 1987. The program's focus is to foster originial science research projects for high school students that have shown an aptitude and an interest in science. Students are instructed in basic research skills, including developing and conducting original research projects, statistical analysis, scientific writing, and presentation of research at local and national symposia, and science fairs. Upon completion of the third year all students are required to submit a paper, suitable for journal publication, detailing their research. Participating students have gone on to win awards with Westinghouse, Intel, The National Junior Science and Humanities Symposium, the International Science and Engineering Fair, New Jersey Academy of Sciences, and local and regional science fairs and symposia. Participating teachers have been recoginized by the Sigma Xi Research Society of Rutgers University for excellence in science teaching. New Jersey awarded the curriulum a Best Practice Award for 2003. Goals and strategies of the curriculum are detailed in a guide written for the courses. Professional development for the courses and resources for mentoring programs are the responsibility of the District Science Supervisor, and have been fostered over the years with the assistance of local colleges and universities including Rutgers Univesity, Monmouth University, University of Medicine and Dentistry of New Jersey, Liberty Science Center of New Jersey's Partners in Science Program, as well as local industries including Hatco Corporation, Merck Corporation, Englehard Corporation, and Lucent Technologies. Science Research teachers have conducted developmental workshops for school districts interested in implementing similar curricula.

Elementary Teachers' Perceptions of Teaching Science to Improve Student Content Knowledge

NASA Astrophysics Data System (ADS)

Stephenson, Robert L.

The majority of Grade 5 students demonstrate limited science knowledge on state assessments. This trend has been documented since 2010 with no evidence of improvement. Because state accountability formulas include proficiency scores and carry sanctions against districts that fail to meet proficiency thresholds, improved student performance in science is an important issue to school districts. The purpose of this study was to explore elementary teachers' perceptions about their students' science knowledge, the strategies used to teach science, the barriers affecting science teaching, and the self-efficacy beliefs teachers maintain for teaching science. This study, guided by Vygotsky's social constructivist theory and Bandura's concept of self-efficacy, was a bounded instrumental case study in which 15 participants, required to be teaching K-5 elementary science in the county, were interviewed. An analytic technique was used to review the qualitative interview data through open coding, clustering, and analytical coding resulting in identified categorical themes that addressed the research questions. Key findings reflect students' limited content knowledge in earth and physical science. Teachers identified barriers including limited science instructional time, poor curricular resources, few professional learning opportunities, concern about new state standards, and a lack of teaching confidence. To improve student content knowledge, teachers identified the need for professional development. The project is a professional development series provided by a regional education service agency for K-5 teachers to experience science and engineering 3-dimensional learning. Area students will demonstrate deeper science content knowledge and benefit from improved science instructional practice and learning opportunities to become science problem solvers and innovative contributors to society.
