Identifying Productive Resources In Secondary School Students' Discourse About Energy, Benedikt Walter Harrer

Electronic Theses and Dissertations

A growing program of research in science education acknowledges the beginnings of disciplinary reasoning in students’ ideas and seeks to inform instruction that responds productively to these disciplinary progenitors in the moment to foster their development into sophisticated scientific practice. This dissertation examines secondary school students’ ideas about energy for progenitors of disciplinary knowledge and practice. Previously, researchers argued that students’ ideas about energy were constrained by stable and coherent conceptual structures that conflicted with an assumed unified scientific conception and therefore needed to be replaced. These researchers did not attend to the productive elements in students’ ideas about energy. …

Evolving Minds: Helping Students With Cognitive Dissonance, Terry L. Bramschreiber

Electronic Theses and Dissertations

Even 150 years after Charles Darwin published On the Origin of Species, public school teachers still find themselves dealing with student resistance to learning about biological evolution. Some teachers deal with this pressure by undermining, deemphasizing, or even omitting the topic in their science curriculum. Others face the challenge and deliver solid scientific instruction of evolutionary theory despite the conflicts that may arise. The latter were the topic of this study.

I interviewed five teachers that had experience dealing with resistance to learning evolution in their school community. Through these in-depth interviews, I examined strategies these teachers use when …

Formative Assessment: Benefit For All, William Wallace

Electronic Theses and Dissertations

This study investigated how formative assessment implemented in a fifth grade mathematics classroom with a student response system and a student self-evaluative tool affected student self-assessment. Data were collected through individual student and focus group interviews, self-assessment sheets, and teacher reflections. Formative assessment is a low stakes classroom assessment that is an assessment for learning. This study used a student response system to convey feedback from the formative assessment to both students and teacher during instruction. The student self-assessment sheet was implemented to provide a more dynamic level of feedback for students than what could be provided through the student …

As a means to support teachers’ facilitating specific student engagement practices, professional development was provided. This study is situated in the growing body of research associated with student engagement and cultural identity. The case of two …

Secondary And Postsecondary Calculus Instructors' Expectations Of Student Knowledge Of Functions: A Multiple-Case Study, Cheryl Avila

Electronic Theses and Dissertations

This multiple-case study examines the explicit and implicit assumptions of six veteran calculus instructors from three types of educational institutions, comparing and contrasting their views on the iteration of conceptual understanding and procedural fluency of pre-calculus topics. There were three components to the research data recording process. The first component was a written survey, the second component was a "think-aloud" activity of the instructors analyzing the results of a function diagnostic instrument administered to a calculus class, and for the third component, the instructors responded to two quotations. As a result of this activity, themes were found between and among …

Pre-Service Elementary Teachers' Self-Efficacy Beliefs About Science Using Critical Incident Technique: A Case Study Approach., Meera Ravikumar

Electronic Theses and Dissertations

The primary goal of this case study using qualitative and quantitative methods was to investigate pre-service elementary teachers’ initial self-efficacy beliefs about science and science teaching by exploring the K-12 science experiences of these prospective elementary teachers. Of the 108 participants who completed the science teaching efficacy belief survey (STEBI-B) (Enochs & Riggs, 1990), 12 participants were selected to be interviewed using Flanagan’s (1954) critical incident technique. Participants were asked to share their past positive and negative incidents during their K- 12 years with science and science teachers. They were also asked to report how past incidents affected them at …

Inquiry, Efficacy, And Science Education, Heather Christa Scott

Electronic Theses and Dissertations

Developing learners who are equipped to think critically about the vast information circulating around them is essential in their preparation for a role in society today. The use of effective inquiry-based instruction is not a widespread practice among K-12 classrooms. Many secondary and post-secondary science instructors see the valuable link between students asking questions and the development of critical thinking. Inquiry-based instruction provides student opportunities to ask questions, design methods of investigation, gather information, and finally reach conclusions based on evidence. However, this instruction style is rarely used in the classroom, particularly in elementary classrooms. This study examines the relationships …

Knowledge, Attitudes And Practices Of Environmental Justice In Higher Education, Marjorie M. Nussbaum

Electronic Theses and Dissertations

Research suggests that issues of environmental justice are not being routinely included in the curriculum of the K-12 classroom and that teachers in those grades do not feel prepared to teach it. Likewise, little has been written about the addition of these topics to higher education coursework, leaving the question of inclusion at this level of education as well. This apparent lacuna may point to at least one reason why K-12 teachers are neither knowledgeable about environmental justice nor prepared to teach it. To discover the current state of inclusion in higher education, a mixed methods study was conducted to …
