Pre‐Service Teachers’ Use Of Content Knowledge To Inform Formative Assessment Strategies In An Integrated Life Sciences Methods Course, Jaime Sabel, Cory Forbes 2014 University of Nebraska - Lincoln

Pre‐Service Teachers’ Use Of Content Knowledge To Inform Formative Assessment Strategies In An Integrated Life Sciences Methods Course, Jaime Sabel, Cory Forbes

DBER Speaker Series

Pre‐service elementary teachers should learn essential science concepts, how to apply those concepts to practice in elementary science learning environments, and how to effectively connect students’ ideas to appropriate instructional strategies. In order to effectively engage students in scientific practices and connect students’ ideas about science to appropriate instructional strategies, teachers should learn to engage in high‐leverage instructional practices, such as formative assessment. However, teachers may not understand formative assessment or possess enough science content knowledge to effectively engage in related instructional practices. To address these needs, we developed an innovative course for elementary pre‐service teachers built ...


Plumbdads And Quarkles: Discussing Modeling Trends With Students Using Fictional Parameters, Timothy Grove 2014 Indiana University – Purdue University Fort Wayne

Plumbdads And Quarkles: Discussing Modeling Trends With Students Using Fictional Parameters, Timothy Grove

Physics Faculty Publications

Helping students develop an understanding of how to interpret experimental data trends is an important part of the introductory physics laboratory. Unfortunately, many of my colleagues have lamented that too many of their students do this poorly. This is a common refrain, and past research has already revealed student difficulties with measurement, uncertainty, and the overall meaning of data.1–3 Like many instructors, I prefer discovery-style labs and in many laboratory investigations students are asked to use curve-fitting tools to discover a relationship.4 But one day in lab, I began to wonder if students were looking at data ...


Thinking It Through: Australian Students’ Skills In Creative Problem Solving, Lisa De Bortoli, Greg Macaskill 2014 Australian Council for Educational Research

Thinking It Through: Australian Students’ Skills In Creative Problem Solving, Lisa De Bortoli, Greg Macaskill

OECD Programme for International Student Assessment (PISA Australia)

In every PISA survey, students from every participating country are assessed in the core domains of mathematics, science and reading literacy. In addition to assessing these literacy domains, the OECD proposes additional assessments in other domains. In PISA 2003, a paper-based assessment of cross- disciplinary problem solving was first assessed, when it was included as a core domain. In PISA 2012, problem solving was once again assessed, this time as an optional computer-based assessment.

The focus of the PISA 2012 assessment of problem solving was: Are today’s 15-year-old students acquiring the problem-solving skills that will prepare them to meet ...

Using Outreach To Inform, Maintain And Evaluate Your Collection [Presentation Slides], Kiyomi D. Deards

Library Conference Presentations and Speeches

Increasing responsibilities, coupled with larger student bodies and corresponding increases in teaching and research faculty and staff, have made it difficult for many librarians and information professionals to spend time on collection development. This presentation will demonstrate how both formal and informal outreach efforts can inform collection development of Chemistry resources, the evaluation of existing resources, and guide collection maintenance efforts.


Statistical Models Of Self-Efficacy In Stem Students, Sarah Painter 2014 Minnesota State University, Mankato

Statistical Models Of Self-Efficacy In Stem Students, Sarah Painter

Journal of Undergraduate Research at Minnesota State University, Mankato

Persistence through undergraduate education may be explained by self-efficacy. It is the belief in one’s self to persevere through challenges. Bandura stated four areas that are thought to influence self-efficacy: mastery experience, social persuasion, vicarious experience, and physiological state. In this study, we focused on general and academic self-efficacy in STEM students, in the hopes of learning more about the relationships between Bandura’s categories, demographics, and self-efficacy. Data was taken from two institutions: one, a large research focused university, and the other, a smaller teaching focused university. In the first phase, surveys on general self-efficacy were taken at ...

Prospective Elementary Mathematics Teacher Content Knowledge: What Do We Know, What Do We Not Know, And Where Do We Go?, Eva Thanheiser, Christine Browning, Alden Edson, Jane-Jane Lo, Ian Whitacre, Dana Olanoff, Crystal Morton

Mathematics and Statistics Faculty Publications and Presentations

The authors reviewed 112 research studies from 1978 to 2012 on prospective elementary teachers' content knowledge in five content areas: whole numbers and operations, fractions, decimals, geometry and measurement, and algebra. Looking across these studies, this final paper identifies the trends and common themes in terms of the counts and types of studies and commonalities among findings. Analyses of the counts show that the number of articles published each year focusing on prospective teacher (PT) content knowledge is increasing. Most articles across the content areas show that PTs tend to rely on procedures rather than concepts. However, the focus of ...


Mathematical Content Knowledge For Teaching Elementary Mathematics: A Focus On Whole-Number Concepts And Operations, Eva Thanheiser, Ian Whitacre, George J. Roy 2014 Portland State University

Mathematical Content Knowledge For Teaching Elementary Mathematics: A Focus On Whole-Number Concepts And Operations, Eva Thanheiser, Ian Whitacre, George J. Roy

Mathematics and Statistics Faculty Publications and Presentations

This report represents part of a recent effort to summarize the state of knowledge of prospective elementary teachers' (PTs') mathematics content knowledge and the development thereof. Extensive reviews of the research literature were conducted by a recent PME-NA Working Group across various content areas. This report focuses on whole number and operations. Research in this area is scarce. What we do know from the literature is that PTs' knowledge of whole number and operations is insufficient and in need of improvement. PTs reason about whole numbers and operations in ways that are tied to the standard algorithms. At the same ...


An Interpretive Plan Guide For Wilderness Park In Lincoln, Nebraska, Rachel J. Ward 2014 University of Nebraska - Lincoln

An Interpretive Plan Guide For Wilderness Park In Lincoln, Nebraska, Rachel J. Ward

Community and Regional Planning Program: Professional Projects

Wilderness Park, located in Lancaster County, Nebraska, is a public park of unique ecological and historical value to the city of Lincoln and to the surrounding region. The natural and historical features of the park present an opportunity to communicate environmental and historical topics that are relevant on local, national, and global levels, as well as inspire a lively sense of pride in the community. The problem is that many topics relevant to Wilderness Park are not currently being interpreted at the park, and that there are relatively few interpretive resources available to park visitors.

The purpose of this project ...


Assessment Of Educational Expectations, Outcomes And Benefits From Small Satellite Program Participation, Jeremy Straub, Ronald Marsh 2014 SelectedWorks

Assessment Of Educational Expectations, Outcomes And Benefits From Small Satellite Program Participation, Jeremy Straub, Ronald Marsh

Jeremy Straub

This paper begins to characterize the educational outcomes that can be produced from student participation in a small spacecraft development program. We asked students what benefits they expected to receive from program participation and we asked them, at the end of the semester, what benefits they had received. We also characterized student performance through the use of post-participation Likert-like scale questions and the use of a widely-used questionnaire for assessing student research participation outcomes. We compare benefit expectation and attainment, characterize the level of benefits received across multiple types of participation and assess the effect of program participation on subject-specific ...

STEM Teacher and Researcher (STAR) Program Posters

The Air Force Research Laboratory (AFRL) is undertaking a program to improve the development of a gas-centered swirl coaxial liquid injector. The injector in a liquid rocket engine atomizes and mixes the fuel with the oxidizer to produce efficient and stable combustion that will improve stability performance and provide the required thrust for the rocket engine without endangering hardware durability. The rocket injector has been experimentally investigated by using a combination of methodologies called cold-flow and hot-fire testing which have been scaled by other laboratory facilities. The AFRL identified few condition parameters for hot-firing testing that could be simulated through ...


Energy Surety For Us Army Buildings In Afghanistan, Eric D. Reisweber 2014 California Polytechnic State University

Energy Surety For Us Army Buildings In Afghanistan, Eric D. Reisweber

STEM Teacher and Researcher (STAR) Program Posters

Energy access and reliability are high priorities at the U.S. Army bases in Afghanistan. Using photovoltaic (PV) arrays can help diversify the systems that supply energy to a given area increasing energy safety, security, reliability and sustainability—and thus improving energy surety. PV systems, which convert incoming solar radiation into usable electric power, may be a wise choice for bases in the Middle East because the solar resource is relatively constant and abundant. Solar resource refers to the amount of solar radiation a given location on earth’s surface receives. The solar resource for two locations were investigated in ...

Wind Speed And Seismic Motion Data Analysis, Margarita Vidrio

STEM Teacher and Researcher (STAR) Program Posters

The Laser Interferometer Gravitational Wave Observatory (LIGO) was developed to exploit Einstein's prediction of gravitational waves to develop a new way to study the universe. Gravitational waves are detected by observing changes less than 1/10000 of the diameter of a proton in the distances between hanging mirrors that are four kilometers apart within two perpendicular evacuated tubes. These changes in distances between mirrors are produced by gravitational waves from large masses in space, such as colliding black holes. Many factors affect the sensitivity of the interferometer. LIGO’s Physical Environment Monitoring subsystem (PEM) is one method of both ...


Mother Convict Cichlids Inflict More Bites Upon An Intruder In Hot Temperatures, Jesse L. Heckendorf 2014 California Polytechnic State University

Mother Convict Cichlids Inflict More Bites Upon An Intruder In Hot Temperatures, Jesse L. Heckendorf

STEM Teacher and Researcher (STAR) Program Posters

Convict cichlids (Archocentrus nigrofasciatus) have developed to be extremely good parents by protecting their brood. Parental care leads to aggressive biting, chasing, and gill flaring to intimidate known predators. In this experiment, we show that environmental factors, such as the changing of temperature in this case, affect a female convict cichlid’s aggression toward caring for her offspring when an intruder is introduced. Females attack more in warmer water.


Supporting Representation-Rich Problem-Solving In High School Physics, Lyrica L. Lucas 2014 University of Nebraska - Lincoln

Supporting Representation-Rich Problem-Solving In High School Physics, Lyrica L. Lucas

Theses, Student Research, and Creative Activity: Department of Teaching, Learning and Teacher Education

The literature on physics education research (PER) promotes the use of multiple representations (such as pictures, diagrams, written explanations, and mathematical expressions) to enhance the problem-solving ability of students through instruction. The purpose of this study was to explore the use of a scaffolding strategy that involved the use of multiple representation tasks in problem-solving in a modeling physics class in high school. Another class with similar background was selected as a comparison group. In 12 in-depth problem-solving interviews of students drawn from the two classes, I investigated in detail how the students responded to the multiple representations tasks and ...
