Creating Science Simulations Through Computational Thinking Patterns, Ashok Ram Basawapatna 2012 University of Colorado at Boulder

Creating Science Simulations Through Computational Thinking Patterns, Ashok Ram Basawapatna

Computer Science Graduate Theses & Dissertations

Computational thinking aims to outline fundamental skills from computer science that everyone should learn. As currently defined, with help from the National Science Foundation (NSF), these skills include problem formulation, logically organizing data, automating solutions through algorithmic thinking, and representing data through abstraction. One aim of the NSF is to integrate these and other computational thinking concepts into the classroom. End-user programming tools offer a unique opportunity to accomplish this goal. An end-user programming tool that allows students with little or no prior experience the ability to create simulations based on phenomena they see in-class could be a first step ...


Undergraduate Students’ Conceptions Of Natural And Anthropogenic Climate Change: A Case Study Approach, Thien-Kim Leckie Trenbath 2012 University of Colorado at Boulder

Undergraduate Students’ Conceptions Of Natural And Anthropogenic Climate Change: A Case Study Approach, Thien-Kim Leckie Trenbath

Atmospheric & Oceanic Sciences Graduate Theses & Dissertations

This dissertation shows the evolution of five undergraduate students' ideas of natural and anthropogenic climate change throughout a lecture hall course on climate change. This research was informed by conceptual change theory and students' inaccurate ideas of climate change. Subjects represented different levels of climate change understanding at the beginning of the course and were selected based on their scores on a climate change questionnaire. The study was designed to research how students' ideas changed throughout the course and compare trajectories of lower and higher achieving students. At the beginning, students had different levels of understanding, but as the semester ...

Response To Griffiths, Matthew S. Leifer 2012 Chapman University

Response To Griffiths, Matthew S. Leifer

Mathematics, Physics, and Computer Science Faculty Articles and Research

"First of all, I would like to thank Prof. Griffith for his comments. The exchange has reminded me of the series of letters that appeared in Physics Today following the publication of an article by Chandralekha Singh, Mario Belloni, and Wolfgang Christian on improving the teaching of undergraduate quantum mechanics (see http://ptonline.aip.org/ journals/doc/PHTOAD-ft/vol_60/iss_3/8_1.shtml). In those responses, both Griffiths and Travis Norsen argued that students’ understanding of quantum mechanics would be vastly improved if they were taught more about the foundations of quantum theory, and I wholeheartedly agree with that sentiment. The ...

The Let’s Count pilot early mathematics program was implemented in five early childhood educational contexts across Australia during 2011. The program used specifically formulated materials and workshops to enlist the assistance of early childhood educators to work with parents and other family members of children in their settings to help develop these children’s awareness, confidence and skills in early mathematics. The pilot program was evaluated by the authors of this paper using a multi-methods approach. The evaluation was focused on the success of the Let’s Count program in bringing early childhood educators, parents and other family members ...


Comparing Fossil Instruction With And Without Analogy Use For Gifted Middle-School Students, Tabatha J. Klopp 2012 University of Northern Iowa

Comparing Fossil Instruction With And Without Analogy Use For Gifted Middle-School Students, Tabatha J. Klopp

Graduate Research Papers

Twenty-eight identified gifted elementary to middle school students (n=28) (16 female, 12 male; 26 Caucasian, 1 Hispanic, and 1 Native American), participated in the study of Iowa fossils through form and function analogy compared to self-research of information on the Internet, and practiced new concepts through technology-rich or hands-on craft projects. This study compared using analogical thinking skills along with technology skills to determine the effects on science learning in the elementary gifted classroom. Analogical thinking or teaching is a method recognized as a valuable source of new ideas, a way to transfer previous knowledge to solve new problems ...


Male Students' Perspectives Concerning The Relevance Of Mathematics: Pilot Study Findings, Michael Easey, Elizabeth A. Warren, Vincent Geiger 2012 Australian Catholic University

Male Students' Perspectives Concerning The Relevance Of Mathematics: Pilot Study Findings, Michael Easey, Elizabeth A. Warren, Vincent Geiger

Faculty of Education and Arts Publications

A pilot study was conducted with Year 10 males (N = 154) preparing to make their senior mathematics subject choice. Survey data revealed that students did not understand the different dimensions of relevance of mathematics. Additionally, a statistically significant difference in the level of agreement concerning relevance was identified between students choosing Mathematics A and those choosing both Mathematics B and C. Students choosing both Mathematics B and C perceived mathematics as relevant for facilitating their career pathway, while Mathematics A aspirants acknowledged the relevance of mathematics was less influential, reporting their choice was guided by their mathematical ability.


Student Perception Of Relevance Of Biology Content To Everyday Life: A Study In Higher Education Biology Courses, Agnes Rose Himschoot 2012 Olivet Nazarene University

Student Perception Of Relevance Of Biology Content To Everyday Life: A Study In Higher Education Biology Courses, Agnes Rose Himschoot

Faculty Scholarship – Biology

The purpose of this mixed method case study was to examine the effects of methods of instruction on students’ perception of relevance in higher education non-biology majors’ courses. Nearly ninety percent of all students in a liberal arts college are required to take a general biology course. It is proposed that for many of those students, this is the last science course they will take for life. General biology courses are suspected of discouraging student interest in biology with large enrollment, didactic instruction, covering a huge amount of content in one semester, and are charged with promoting student disengagement with ...


The Effectiveness Of Blended Instruction In Core Postsecondary Mathematics Courses, Anna E. Bargagliotti, Fernanda Botelho, Jim Gleason, John Haddock, Alistair Windsor 2012 Loyola Marymount University

The Effectiveness Of Blended Instruction In Core Postsecondary Mathematics Courses, Anna E. Bargagliotti, Fernanda Botelho, Jim Gleason, John Haddock, Alistair Windsor

Mathematics Faculty Works

Most students in U.S. universities are required to take a collection of core courses regardless of their degree or major. These courses are known as "general education" courses. The general education requirements typically include at least one mathematics course. Unfortunately each year hundreds of thousands of students in the US do not succeed in these general education mathematics courses causing them to act as a barrier to degree completion. Low student success rates in these courses are pervasive, and it is well documented that the U.S. needs to improve student success and retention in general education mathematics courses ...

A Descriptive, Survey Research Study Of The Student Characteristics Influencing The Four Theoretical Sources Of Mathematical Self-Efficacy Of College Freshmen, Tonja Motley Locklear 2012 University of Kentucky

A Descriptive, Survey Research Study Of The Student Characteristics Influencing The Four Theoretical Sources Of Mathematical Self-Efficacy Of College Freshmen, Tonja Motley Locklear

Theses and Dissertations--Science, Technology, Engineering, and Mathematics (STEM) Education

The Sources of Middle School Mathematics Self-Efficacy Scale (Usher & Pajares, 2009) was adapted for use in this study investigating the impact that gender, race, sexual orientation, hometown location (rural, suburban, or urban), high school GPA, college GPA and letter grade of a mathematics course in the previous semester had on the four sources of mathematical self-efficacy of 102 college freshmen attending three small, private, liberal arts institutions. Even though this study found no interaction effects between the student characteristics, the four sources of mathematical self-efficacy, or the three subcategories of the vicarious experience construct, this study did find statistically significant ...


Distrusting Climate Science: A Problem In Practical Epistemology For Citizens, Thomas Atchison 2012 Metropolitan State University

Distrusting Climate Science: A Problem In Practical Epistemology For Citizens, Thomas Atchison

Iowa State University Summer Symposium on Science Communication

I briefly present empirical findings suggesting that citizens in contemporary democracies face great difficulties in arriving at an accurate picture of the world and of the relevant policy options and in identifying trustworthy sources of information. Unfortunately, these difficulties do not seem to diminish with more education or with more effort and attention. I argue that a highly polluted information environment can defeat the sorts of strategies generally recommended to individuals under the label 'critical thinking.’ Finally, I consider what sort of institutional or systemic conditions would be necessary to provide citizens with a manageable epistemic task.


Co-Evolving Expertise In Environmental Policy Debates: Rethinking Values And Participants Through An Ecological Model Of Rhetoric, Piper Corp 2012 University of Pittsburgh

Co-Evolving Expertise In Environmental Policy Debates: Rethinking Values And Participants Through An Ecological Model Of Rhetoric, Piper Corp

Iowa State University Summer Symposium on Science Communication

Environmental policy controversies reflect a struggle between “subjective” (human) and “objective” (scientific) knowledge, which a more rhetorical science could reconcile. I draw from actor network theory and rhetorical identification to suggest a model of ecological rhetoric, which I apply to two science policy projects: ecosystem service markets and adaptive management.


What Is “Responsible Advocacy” In Science? Good Advice., Jean Goodwin 2012 Iowa State University

What Is “Responsible Advocacy” In Science? Good Advice., Jean Goodwin

Iowa State University Summer Symposium on Science Communication

Debates over scientists’ appropriate contributions to policy-making are prominent in a variety of natural resources fields. The issue is often presented as one of “responsible advocacy.” But this framing locks us into a paradox: Scientists who advocate aim to be effective in the policy arena, but by advocating lose their credibility. In this preliminary review of the issue, I argue that we can avoid the paradox by acknowledging a wider range of speech acts structuring scientists’ obligations in the policy process. Scientists can advocate–but they can also report, give their assessments, make recommendations, and especially, offer good advice.


Using Delphi To Track Shifts In Meanings Of Scientific Concepts In A Long-Term, Expert-Lay Collaboration On Sustainable Agriculture Research In The Midwest, Nancy Grudens-Schuck, G. L. Drake Larsen 2012 Iowa State University

Using Delphi To Track Shifts In Meanings Of Scientific Concepts In A Long-Term, Expert-Lay Collaboration On Sustainable Agriculture Research In The Midwest, Nancy Grudens-Schuck, G. L. Drake Larsen

Iowa State University Summer Symposium on Science Communication

Dilemmas for ongoing expert-lay collaborations for agricultural conservation include divergence of meaning of new scientific concepts. Delphi method documented stakeholders’ understandings of a new term, “ecosystem services.” Flood mitigation and pest management benefits as ecosystem service attributes were ranked lower by stakeholders than anticipated by scientists. Recreation and aesthetics, and food production, were ranked higher.


Examples, Illustrations, Inductions, Anecdotes, Analogies, Precedents, Narratives, And Personal Testimonies: Are They Essentially Different?, Dale Hample 2012 University of Maryland

Examples, Illustrations, Inductions, Anecdotes, Analogies, Precedents, Narratives, And Personal Testimonies: Are They Essentially Different?, Dale Hample

Iowa State University Summer Symposium on Science Communication

This essay addresses the question of whether these argument schemes—example, illustration, induction, anecdote, analogy, precedent, narrative, and personal testimony—are distinct from one another. Each of them is essentially based on a single case (although the cases can be multiplied, perhaps converging into an informal induction). “Example” is the prototypical scheme. The critical questions for “example” apply to the other argument schemes as well.


Authority In An Age Of Expertise, Catherine E. Hundleby 2012 University of Windsor

Authority In An Age Of Expertise, Catherine E. Hundleby

Iowa State University Summer Symposium on Science Communication

The potential for experts to exploit their positions of authority requires attention to the role of epistemic work as part of the social division of labour. Expertise has not become so distant from social hierarchy as we sometimes fancy, and evaluating expertise requires political analysis.


Deliberative Systems View Of Efforts To Democratize Energy In Arizona, Travis Johnson 2012 Arizona State University

Deliberative Systems View Of Efforts To Democratize Energy In Arizona, Travis Johnson

Iowa State University Summer Symposium on Science Communication

Science often struggles to find answers in a world of complexity and uncertainty and deliberative democracy has been used as a way to bring in public values to help guide the scientific process. This study looks at Arizona’s energy system through a theoretical lens and three separate efforts to democratize dialogue around energy in Arizona. The Arizona Town Hall, Emerge and the Solar Summit are all efforts to engage a more diverse range of stakeholders and keep dialogue progressing.
