Using Inquiry To Teach Microscope Skills, Susan Styer Oct 2012

Using Inquiry To Teach Microscope Skills, Susan Styer

Faculty Publications & Research

One of the first lab activities often done in a high school biology course is learning to use the microscope. As it is typically described in laboratory manuals, there is no inquiry involved in this activity. Students learn the parts of the microscope and information explaining its operation. There may be a review of the metric system. Then students examine cells, often to observe the difference between plant and animal cells. Students may be instructed to prepare wet mounts and do simple staining. All of these are important skills to have in order to use the microscope correctly, but it …

The Tower Builders: A Consideration Of Stem, Stse And Ethics In Science Education, Astrid Steele, Christine R. Brew, Brenda R. Beatty Oct 2012

The Tower Builders: A Consideration Of Stem, Stse And Ethics In Science Education, Astrid Steele, Christine R. Brew, Brenda R. Beatty

Australian Journal of Teacher Education

The call for the integration of ethical considerations in the teaching of science is now firmly on the agenda. Taking as illustrative a science lesson in a pre-service teacher class, the authors consider the roles of STSE (science, technology, society and environment) and the increasingly influential heavily funded STEM (science, technology, engineering and mathematics) education initiatives. The origins and foci of both initiatives are discussed, as are their disparate ontological foundations. The use of Habermas’ knowledge theories in conjunction with ethical frameworks is posited as a way of considering both STSE and STEM perspectives and their implications for strengthening science …


Two Sides Of The Megalopolis: Educating For Sustainable Citizenship, Alexander Pope, Timothy Patterson Oct 2012

Two Sides Of The Megalopolis: Educating For Sustainable Citizenship, Alexander Pope, Timothy Patterson

Education Faculty Publications

Despite widespread focus on literacy and math at the expense of other subjects, citizenship and environmental education have an important role in American public education. Citizenship and environmental education are broadly tasked with helping students develop the knowledge, skills, and attitudes needed to shepherd the body politic and natural world, respectively, into the future. For educators and administrators concerned with instructional efficiency, educational farm visits offer one means of pairing these two approaches into a unified learning experience. This paper presents findings from a qualitative case study analysis of two such programs, incorporating interviews with and observations of visiting students, …


Instructor Use Of Tablet Pcs In A College Pre-Calculus Course: Implementation & Assessment, Julianna Connelly Stockton, Peter Gregory Oct 2012

Instructor Use Of Tablet Pcs In A College Pre-Calculus Course: Implementation & Assessment, Julianna Connelly Stockton, Peter Gregory

Mathematics Faculty Publications

A group of six math instructors used tablet PCs to teach their individual sections of a high enrollment gateway Pre-Calculus course in a diverse urban four-year college. Student performance in the experimental sections were compared to those in 31 other sections in terms of student retention, pass rates, and score on the department-wide standardized final exam. Student performance was higher in Tablet PC sections across all three measures, although in some cases the improvement was not substantial enough to improve students’ overall course grades. Surveys of students and faculty in classes using a Tablet PC reflected overall positive impressions of …


Number Sense Mediated By Mathematics Self-Concept In Impacting Middle School Mathematics Achievement, Lara K. Geronime Oct 2012

Number Sense Mediated By Mathematics Self-Concept In Impacting Middle School Mathematics Achievement, Lara K. Geronime

Dissertations (1934 -)

The purpose of the current study was to extend the research on number sense to the middle school level and to simultaneously consider socioemotional elements related to the construct at this developmental stage. Its genesis was initially rooted in an ongoing and dramatic emphasis by U.S. policymakers, researchers, and educators on improving mathematics achievement in order to compete globally in technology and innovation. Despite debates about optimal curriculum and instruction, tremendous support exists for the construct of number sense. However, middle school research examining the phenomena has been limited to intervention protocols targeting specific skillsets and better measurement of its …

Young Children’S Understanding Of Conservation Concepts, Julia C. Torquati

Discipline-Based Education Research Group Speaker Series

This presentation will summarize an investigation of young children’s conservation knowledge and reasoning. Eighty‐two preschool aged children (3‐5 years) were interviewed at two points in time six months apart using a semi‐structured interview. The interview protocol developed by Peter Kahn (2001) was used to assess children’s conservation attitudes. This was the first time the interview was used with preschool aged children. Children were asked questions about the importance of animals, plants, parks, and gardens, and whether it is acceptable to litter (and why or why not). Fifty‐seven of the children attended a preschool located at a nature center, ten children …

An Item Response Curves Analysis Of The Force Concept Inventory, Gary A. Morris, Nathan Harshman, Lee Branum-Martin, Eric Mazur, Taha Mzoughi, Stephen D. Baker Sep 2012

An Item Response Curves Analysis Of The Force Concept Inventory, Gary A. Morris, Nathan Harshman, Lee Branum-Martin, Eric Mazur, Taha Mzoughi, Stephen D. Baker

Faculty Articles

Several years ago, we introduced the idea of item response curves (IRC), a simplistic form of item response theory (IRT), to the physics education research community as a way to examine item performance on diagnostic instruments such as the Force Concept Inventory (FCI). We noted that a full-blown analysis using IRT would be a next logical step, which several authors have since taken. In this paper, we show that our simple approach not only yields similar conclusions in the analysis of the performance of items on the FCI to the more sophisticated and complex IRT analyses but also permits additional …

General Aviation Weather Encounter Case Studies, John M. Lanicci, Massoud Bazargan, Daniel Halperin, Scott Shappell, Jaclyn Baron, Rebecca Iden, Carla Hackworth, Kali Holcomb

School of Graduate Studies - Daytona Beach

This study presents a compilation of 24 cases involving general aviation (GA) pilots’ weather encounters over the continental U.S. The project team interviewed pilots who had experienced a weather encounter, and we examined their backgrounds, flight experience, and weather encounter details. Results from meteorological data analysis for each weather encounter were consistent with findings of larger GA weather accident studies in terms of the types of hazards encountered and flight phase during which the encounters occurred. Investigation of pilot weather products and the sources from which they were obtained revealed a lack of uniformity of pre-flight data sources and underutilization …


The Relationship Between The Level Of Special Education Instructional Support Segments And The Academic Achievement Of Students With Emotional Behavior Disorders, Marykay Berry Sep 2012

The Relationship Between The Level Of Special Education Instructional Support Segments And The Academic Achievement Of Students With Emotional Behavior Disorders, Marykay Berry

Doctoral Dissertations and Projects

Researchers have extensively studied the effects of placement on academic and behavioral interventions for students with disabilities and have found varying results. A correlational research design was used to determine if there was a relationship between the level of special education support (amount of time spent with special education support) for students with emotional behavior disorders (EBD) and student achievement in reading and math as measured by performance on the Georgia Criterion Referenced Competency Test (CRCT). The study included 81 students with EBD in a small rural school district in Georgia in grades six through eight over the 2007-2008, 2008-2009, …


Links And Distinctions Among Citizenship, Science, And Citizen Science. A Reponse To "The Future Of Citizen Science.", Caren B. Cooper Aug 2012

Links And Distinctions Among Citizenship, Science, And Citizen Science. A Reponse To "The Future Of Citizen Science.", Caren B. Cooper

Democracy & Education

Mueller, Tippins, and Bryan (2012) presented a new conceptualization of citizen science that is meant to facilitate emerging trends in the democratization of science and science education to produce civically engaged students. I review some relevant trends in the field of citizen science, for clarity here referred to as public participation in scientific research (PPSR), and present overlooked styles and outcomes of PPSR. Education efforts should seize the opportunity to emphasize the key and distinct roles students can play in both the science and the values elements that inform decision-making processes.


Citizen(S’) Science. A Response To "The Future Of Citizen Science", Angela M. Calabrese Barton Aug 2012

Citizen(S’) Science. A Response To "The Future Of Citizen Science", Angela M. Calabrese Barton

Democracy & Education

Citizen science is fundamentally about participation within and for communities. Attempts to merge citizen science with schooling must call not only for a democratization of schooling and science but also for the democratization of the ways in which science is taken up by, with, and for citizen participants. Using this stance, along with critical studies of place, I build on the criticisms of citizen science outlined in "The Future of Citizen Science" to argue for the centrality of place. Using a case of urban youths working toward transparency and cross-cultural dialogue regarding energy production in their community, I complicate the …


Student Teachers' Interactive Decisions With Respect To Student Mathematics Thinking, Jonathan J. Call Aug 2012

Student Teachers' Interactive Decisions With Respect To Student Mathematics Thinking, Jonathan J. Call

Theses and Dissertations

Teaching mathematics is a difficult and complicated task. For student teachers, who are extremely new to the mathematics classroom, this difficulty is magnified. One of the biggest challenges for student teachers is learning how to effectively use the student thinking that emerges during mathematics lessons. I report the results of a case study of two mathematics education student teachers. I focus on how they make decisions while teaching in order to use their students' mathematical thinking. I also present analysis of the student teachers' discourse patterns, the reasons they gave to justify these patterns, and how their reasons affected how …

A Genetic Survey Of English Sole Populations In The Salish Sea, Elizabeth S. Gutierrez, Gary A. Winans, Jon Baker, Amanda Cope

STAR Program Research Presentations

This summer I interned at the Northwest Fisheries Science Center in Seattle, WA and participated in NOAA’s Salish Sea Project. The Salish Sea Project’s goal is to identify genetically distinctive groups of species in the Salish Sea that may have unique evolutionary and/or adaptive backgrounds. These findings will allow NOAA to promote and monitor the natural production of species in the Salish Sea, to select representative populations for experimental work regarding pollution, ocean acidification and climate change, to contribute to managing the ecosystem for intra- and inter-species diversity, and to help make informed decisions about adaptive management and marine protected …


Agent Based Modeling As An Educational Tool, Jonathan H. Fuller, Rodger Johnson, Vic Castillo Aug 2012

Agent Based Modeling As An Educational Tool, Jonathan H. Fuller, Rodger Johnson, Vic Castillo

STAR Program Research Presentations

Motivation is a key element in high school education. One way to improve motivation and provide content, while helping address critical thinking and problem solving skills, is to have students build and study agent based models in the classroom. This activity visually connects concepts with their applied mathematical representation. “Engaging students in constructing [models] may provide a bridge between frequently disconnected conceptual and mathematical forms of knowledge.” (Levy and Wilensky, 2011)

Don’T I Know You? A Misstep In Teaching Mathematics With And For Social Justice In A Rural Context, Joel Amidon Aug 2012

Don’T I Know You? A Misstep In Teaching Mathematics With And For Social Justice In A Rural Context, Joel Amidon

Journal of Contemporary Research in Education

In this paper, I document my own struggles and insights in moving toward a pedagogy of teaching mathematics with and for social justice within a rural high school. Teaching mathematics for social justice has been presented as a way to address the inequities present in the classroom, and the world at large, by having students work with mathematics to question and analyze inequities in their world (Gutstein, 2006). Inclusive education has been presented as a means for providing all students, regardless of their needs, abilities and interests, access to engaging content in the classroom (Villa & Thousand, 2005). These approaches …
