Since the inception of 3D printing, an evolutionary process has taken place in which specific user and customer needs have crossed paths with the capabilities of a growing number of machines to create value-added businesses. Even today, over 30 years later, the growth of 3D printing and its utilization for the good of society is often limited by the various users' understanding of the technology for their specific needs. This article presents an overview of current 3D printing technologies and shows numerous examples from a multitude of fields from manufacturing to education.

Oh, Behave! Behavior As An Interaction Between Genes & The Environment, Emily G. Weigel, Michael Denieu, Andrew J. Gall

The lesson is targeted to meet the educational goals of undergraduate introductory biology, evolution, and animal behavior courses, but it is also suitable for advanced high school biology students. This lesson meets the criteria for the Next Generation Science Standard HS-LS4, Biological Evolution: Unity and Diversity (NGSS Lead States, 2013).

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 the …

Science Teachers' Understandings Of Science Practices Before And After The Participation In An Environmental Engineering Research Experiences For Teachers (Ret) Program, Dilek Özalp

USF Tampa Graduate Theses and Dissertations

In 2012, National Research Council published a new science education framework that explains the science practices and its importance in understanding the process of knowledge development. The students were expected to engage in all the practices by grade 12. All science teachers need some kind of support to improve their understandings of these science practices (NRC, 2012). An important key component of engaging teachers in scientific investigations is to have the teacher participate in a research laboratory experience (NRC, 1996). Research Experiences for Teachers programs (RET) serve as a promising form of professional development to achieve this goal. These programs …

Using Music-Related Concepts To Teach High School Math, Vytas Nagisetty

Dissertations and Theses

The purpose of this research was to test a strategy which uses music-related concepts to teach math. A quasi-experimental study of two high school remedial geometry sections was conducted during a review lesson of ratio, proportion, and cross multiplication. A pretest was given to both groups. Then, Group A received normal textbook instruction while Group B received the treatment, Get the Math in Music, which is an online activity involving proportional reasoning in a music-related context. Afterwards, a posttest was given to both groups. Pretest and posttest scores were used to compare gains in subject knowledge between the groups. Then …

Providing The Fuel (And Passing The Flame), Todd Pagano

Journal of Science Education for Students with Disabilities

At the risk of opening with a cliché statement- at the heart of the most effective mentor is a burning passion. The fuel for this passion is a desire to convince, not just try to, but actually convince your mentee that you care about their success (be it in the classroom, career, or personal life). I am guilty of believing in, and living by, this cliché. However, despite passion being my primary motivator, I am not unwilling to admit that rationale for mentoring can sometimes transcend this ethically normative line of thinking. I believe that there are also sometimes quantitative, …

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

University of Nebraska-Lincoln Libraries: Presentations

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

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 both institutions …

Engaging Non-Science Majors In The Chemistry Around Us Through Information Literacy, Theresa M. Nawalaniec, Reiko M. Simmons

Michael Schwartz Library Publications

Everyone knows that teaching chemistry to non-science majors can be a special challenge! In “Chemistry in Context”, published by ACS, a heavy emphasis is placed on helping students to appreciate “chemistry” in every part of their daily lives. In our attempts to find a balance between teaching the typical basic chemistry topics and related societal issues, a program was developed to involve students in group, mini-research projects. The major purpose of this “project” was to: encourage students to search out chemistry-related information in their areas of interest, recognize the connections between scientific knowledge and our modern everyday lives, and to …

Gender And Mathematics: Quality And Equity, Sue Thomson

2009 - 2019 ACER Research Conferences

Over the past two decades, there have been no gender differences in mathematics achievement in Australia in large-scale international surveys such as the Trends in International Mathematics and Science Study (TIMSS). Similarly, when mathematical literacy was measured in the Programme for International Student Assessment (PISA) in 2003, there were no gender differences. However, PISA 2012 found that, while average scores in mathematics had declined in Australia, males in Australia were significantly outperforming females, and females had significantly higher average levels of anxiety about and significantly lower levels of confidence in mathematics. In light of the recent report of the Australian …

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

STAR Program Research Presentations

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 this study using …

Using Remote Sensing Data To Predict The Spread Of Mosquito Borne Disease, Mary Ellen O'Donnell, Erika Podest

STAR Program Research Presentations

There is interest in how environmental variables derived from satellite data such as temperature, vegetation cover, and precipitation correlate to vector borne disease occurrence such as malaria and dengue fever. This study will be carried out using a decision tree based open source software called Random Forests to find correlations between the remote sensing variables and mosquito abundance. Software will be written in C# to take large amounts of data from the NASA satellite database and automatically format it for the Random Forest Software input. Correlations found, using Random Forests, between disease incidence and the variables can be used as …

Wind Speed And Seismic Motion Data Analysis, Margarita Vidrio

STAR Program Research Presentations

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 eliminating noise and …

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

STAR Program Research Presentations

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.

Injector Configuration And Development Of A Methodology To Scale Between Cold-Flow And Hot-Fire Evaluations, Ilian Angel Rojas, Nils Sedano

STAR Program Research Presentations

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 …

Experiential Learning At The Illinois Mathematics And Science Academy, Michelle Kolar, Dora Phillips, Christopher G. Kolar

Publications & Research

“Am I ever going to use this in the real world?” is a common question in science and math middle school and high school classrooms. Students taught using experiential learning techniques, however, already know the answer. They learn content by solving real world problems through hands-on activities. In other words, they learn science, technology, engineering, and math (STEM) the same way professionals do every day—by doing, sharing, and improving. Experiential learning provides the promise that the U.S. can reverse the trend of students losing interest in STEM subjects during middle school and create life-long learners who apply the scientific thought …

The Effects Of Combining Looping, Cognitively Guided Instruction, And Ethnicity: How They Can Collectively Improve Academic Achievement, Matthew Brandon Wilson

Graduate Theses and Dissertations

The purpose of this quantitative study is to gain an understanding of the powerful instructional potential of combining the practice of looping, Cognitively Guided Instruction (CGI) professional development strategies, and the impact these practices have in addition to ethnicity in elementary education. The study focused on research questions pertaining to student's Measure of Academic Progress (MAP) scores and the implementation of looping, CGI strategies, and how ethnicity impacted student achievement.

This study emphasizes two types of statistical tests to determine how significant CGI and looping practices impacted growth in mathematics on the MAP test for different ethnic groups. A Chi-Square …

The Relationship Between Teaching Approaches And Student Science Achievement For Four Racial Groups In Us Eighth Grade Classes, Su Gao

UNLV Theses, Dissertations, Professional Papers, and Capstones

Lower science achievement and substantial racial performance gaps persist among students in the US. In the current reform of science teaching, inquiry-based science teaching is assumed effective in improving all student science learning in both scientific content and process and reducing learning gaps across racial groups. Conversely, traditional didactic science teaching is believed to be the most popular and has contributed to lower science achievement and the racial gap. These two assumptions, although central to science teaching reforms, cannot be empirically sustained in the existing literature on science teaching. Framed through the theoretical perspectives of inquiry-based instruction and culturally relevant …

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

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 …

The Experiences Of Women In Post Graduate Physics And Astronomy Programs: The Roles Of Support, Career Goals, And Gendered Experiences, Ramón S. Barthelemy

Dissertations

In physics and astronomy the low representation of women is obvious at every stage of the educational pathway from undergraduate students to full professors. These low numbers perpetuate themselves by failing to create new mentors to foster the next generation of women. Women and men also have different experiences as they traverse into physics and astronomy careers. Women often experience chilly climates, discrimination, and challenges coordinating the demands of young families with their careers. In the literature exploring this topic, little focus is put on the experiences of women graduate students in physics and no focus is put on women …

Evaluating The Use Of The Math Reasoning Inventory For Improvement In Fraction Instruction, Kathy Huffman Boyer

Dissertations

In an attempt to close the mathematic achievement gap between students from the United States and students from other countries, a new national set of standards, the Common Core State Standards for Mathematics, was developed and adopted by the state of Michigan in 2010. These standards emphasize mathematical reasoning and application, rather than the previous emphasis on performing calculations. Unfortunately, teachers generally have had little training in how to assess students’ mathematical reasoning, how to teach mathematical reasoning, or how to provide remediation to those students who show need. The purpose of this study was to see if use of …

Instructional Change In Academic Departments: An Analysis From The Perspective Of Two Environment-Focused Change Strategies, Kathleen M. Quardokus

Dissertations

Numerous reports demand changes in college and university teaching practices. This is especially true for science, technology, engineering and mathematics (STEM) disciplines. STEM stakeholders are concerned about student retention within STEM majors, as well as the lack of sufficient graduates with the knowledge to advance these fields. A common conclusion of these reports is that teaching practices must change. Although these calls for change have occurred for decades, STEM fields have yet to experience widespread change. Thus, there is a need for more effective change strategies. Recently, researchers have suggested that effective change strategies should focus on changing the environments …
