Pre-Service Teachers Learning To Generate Evidence-Based Hypotheses On The Effects Of Teaching On Student Learning, Cathery Yeh, Rossella Santagata
Pre-Service Teachers Learning To Generate Evidence-Based Hypotheses On The Effects Of Teaching On Student Learning, Cathery Yeh, Rossella Santagata
Education Faculty Articles and Research
This study examines the development of a specific sub-skill for studying and improving teaching—the generation of hypotheses about the effects of teaching on student learning. Two groups of elementary preservice teachers (PSTs) were compared: one group that attended a typical mathematics-methods course and one that attended a course integrating analysis skills for learning from teaching. Data consist of PSTs’ comments on video clips of mathematics instruction administered before and after course completion. Findings reveal that PSTs at the beginning of the program struggled to generate hypotheses with relevant evidence, often equating teacher behavior or student correct answers as evidence of …

Seeking Research-Enhanced Geoscience Outreach That Complements Subject Knowledge With Pedagogical Expertise (Book Review), Elizabeth Lewis
Department of Teaching, Learning, and Teacher Education: Faculty Publications
This new volume in Springer’s series on Innovations in Science Education and Technology, edited by Tong, provides a window into geoscience education outreach projects and programs developed and implemented by geoscientists for the public, schools, teachers and students, and community members. In his introduction, Tong advocates for geoscientists to employ a ‘research-enhanced outreach model’ versus a ‘research-dissemination model’, in which both scientific and educational research findings inform outreach to schools and the general public. Tong proposes a long-term goal of inclusiveness when building relationships among geoscientists, educational systems and programs, and the public in response to his own critique of …

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 …

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.

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

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 …

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

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 …

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 …

Supporting Representation-Rich Problem-Solving In High School Physics, Lyrica L. Lucas
Department of Teaching, Learning, and Teacher Education: Dissertations, Theses, and Student Research
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 …

The Magnetopause: Bringing Space Physics Into A Junior Lab, Jim Crumley, Ari Palczewski,, Stephen Kaster
MapCores Faculty Publications
Undergraduate students often have minimal exposure to many subfields
of physics which are active areas of research. Space physics
is an area that is particularly difficult to expose students to since
it builds off of another area that most undergraduates see little of,
plasma physics. The magnetopause is convenient entry point
into space physics, since it can be modeled as a pressure balance, which is
a concept familiar from introductory physics. We use the Earth's
magnetopause as the basis for a lab for junior physics majors. In
the lab students analyze results from a NASA MHD simulation and
data from …
How Do They Know It Is A Parallelogram? Analysing Geometric Discourse At Van Hiele Level 3, Sasha Wang, Margaret Kinzel
How Do They Know It Is A Parallelogram? Analysing Geometric Discourse At Van Hiele Level 3, Sasha Wang, Margaret Kinzel
Mathematics Faculty Publications and Presentations
In this article, we introduce Sfard's discursive framework and use it to investigate prospective teachers' geometric discourse in the context of quadrilaterals. In particular, we focus on describing and analysing two participants' use of mathematical words and substantiation routines related to parallelograms and their properties at van Hiele level 3 thinking. Our findings suggest that a single van Hiele level of thinking encompasses a range of complexity of reasoning and differences in discourse and thus a deeper investigation of students' mathematical thinking within assigned van Hiele levels is warranted.

Mathematics Education has at its core a conception of the mathematical performances that represent the aspirations of the mathematics classroom and curriculum. These performances are constituted through teacher and student participation in the activities stimulated by mathematical tasks selected by the teacher for the realization of an instructional purpose. In this nexus of activity, intention, interpretation and consequence, the mathematical task occupies a central place. This Research Forum provides an opportunity to explore and reflect upon the role that mathematical tasks play in the achievement of the goals of the international mathematics education community. Further, consistent with current curricular and …

Developing A Measure Of Scientific Literacy For Middle School Students, Helenrose Fives, Mark Nicolich, Amanda Birnbaum, Wendy Huber
Department of Public Health Scholarship and Creative Works
Scientific literacy reflects “a broad and functional understanding of science for general education purposes” (DeBoer, 2000, p. 594). Herein, we present the ongoing development of the Scientific Literacy Assessment (SLA), a work‐in‐progress measure to assess middle school students' (ages 11–14) scientific literacy. The SLA includes a selected response measure of students’ demonstrated scientific literacy (SLA‐D) and a motivation and beliefs scale based on existing measures of self‐efficacy, subjective task value, and personal epistemology for science (SLA‐MB). Our theoretical conceptualization of scientific literacy guided the development of our measure. We provide details from three studies: Pilot Study 1 (n = …

Being an educator in the twenty-first century is exciting, stimulating, fun, challenging, and dynamic - with a great emphasis on the challenging and dynamic. The scope and depth of the materials we teach, or can teach, to our students is overwhelming and increasing exponentially every year. The list of challenges for science educators is formidable. We have found that one logical piece of the puzzle to help address these challenges is for educators to invite practicing and real-world researchers, engineers, doctors, business owners, and other STEM (science, technology, engineering, mathematics) professionals into the classroom, or take students on field trips …

Carl F. Craver And Lindley Darden: In Search Of Mechanisms: Discoveries Across The Life Sciences, Stuart Glennan
Carl F. Craver And Lindley Darden: In Search Of Mechanisms: Discoveries Across The Life Sciences, Stuart Glennan
Scholarship and Professional Work - LAS
Carl Craver and Lindley Darden are two of the foremost proponents of a recent approach to the philosophy of biology that is often called the New Mechanism. In this book they seek to make available to a broader readership insights gained from more than two decades of work on the nature of mechanisms and how they are described and discovered. The book is not primarily aimed at specialists working on the New Mechanism, but rather targets scientists, students and teachers who are looking for a broad, philosophically and historically informed image of discovery in the life sciences.
