A Study Of The Teaching Beliefs Of The Modern Post Secondary Science Instructor And Implications They May Hold For The Future Of Science Education, Michael Charles Howard

Dissertations

It was the purpose of this study to examine the teaching beliefs of community college science instructors and discover whether their teaching beliefs were student oriented or instructor oriented. In addition, this study sought to examine demographic factors and find their relation, if any, to these teaching beliefs, as well as explore topics that may be useful in the future to helping community colleges science instructors’ curricula and beliefs come together and work in unison. To do this, the study built on the foundation laid by Sampson et al., in their creation of the Beliefs about Reformed Science Teaching and …

A Novel Approach To Using Personal Response Systems And Diagrams To Foster Student Engagement In Large Lecture: Case Study Of Instruction For Model-Based Reasoning In Biology, Johanna M. Fitzgerald

Doctoral Dissertations

At UMass Amherst a method of personal response system (clickers) use in large lecture biology called Guided Application of Model-based Reasoning (GAMBR) has been designed to give students experiences in reasoning like expert biologists: In large lecture biology many instructors appear to use clickers mainly as a quizzing and attendance tool. Less well documented and examined are uses of clickers to facilitate cognitive engagement in learning scientific models and skills. In GAMBR, clicker questions ask students to apply and perturb biological models; this is designed to engage them in model-based reasoning. In an attempt to understand such a course, an …

The Effects Of Emotive Reasoning On Secondary School Students' Decision-Making In The Context Of Socioscientific Issues, Wardell Anthony Powell

USF Tampa Graduate Theses and Dissertations

The discrepancy between what students are being taught within K-12 science classrooms and what they experience in the real world has been well documented. This study sought to explore the ways a high school biology curriculum, which integrates socioscientific issues, impacts students' emotive reasoning and their ability to evaluate evidence, make informed decisions on contemporary scientific dilemmas, and integrate scientific content knowledge in their reasoning on SSI. Both quantitative and qualitative methods were used to examine differences within and between an SSI treatment group and a comparison group as well as individual differences among students' responses over a semester of …

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 …

Describing Students' Talk About Physical Science Phenomena Outside And Inside The Classroom: A Case Of Secondary School Students From Maragoli, Western Region Of Kenya, Grace Nyandiwa Orado

Dissertations - ALL

Because of cultural and linguistic influences on science learning involving students from diverse cultural and linguistic backgrounds, calls have been made for teachers to enact teaching that is sensitive to these students' backgrounds. However, most of the research involving such students has tended to focus on students at elementary grade levels from predominantly two linguistic backgrounds, Hispanic and Haitian Creole, learning science concepts mainly in the life sciences. Also, most of the studies examined classroom interactions between teachers and the students and among students. Not much attention had been paid to how students talk about ideas inherent in scientific phenomena …

Comparison Of The Conceptual Understanding Of Newton's Laws In An Online And Traditional Introductory Physical Science Course, Rex Robert Moak

Dissertations

The purposes of this study were to (a) determine if taking the Physical Science Survey I course in face-to-face (F2F) and online format statistically significantly improves Newtonian conceptual comprehension as measured by the FCI; (b) determine which course format, if any, has statistically significantly higher FCI post-means; and (c) determine if students’ satisfaction with learning is statistically significantly different in the two course formats.

Data for this study was collected from students and faculty in various course formats during the Fall semester of 2012 and the Spring semester of 2013. The researcher used two research tools: the Force Concepts Inventory …

Ideology And Interdisciplinary Science Graduate Education Reform, Benjamin Harrison Allen

Masters Theses

Over the past few decades, a variety of science education reform publications have emerged from both public and private entities, alongside graduate programs established to provide training for integrating multiple disciplines in research activities. Several documents concerning federal education policy have explored the socioeconomic impacts of reforming graduate education in the sciences and have made recommendations for funding interdisciplinary traineeship programs at U.S. universities. On the other hand, much of the current academic literature concerning interdisciplinary graduate science education considers the subject from functionalist perspectives, aiming to contribute best practices for assessment and curricular programming. In contrast to both of …

Novice Science Teachers' Thinking About The Purpose Of Teachers' Questions, Gwyndolyn Crittenden

Electronic Theses and Dissertations

Effective teacher questioning during whole group instruction remains an important pedagogy in science education, especially the importance of helping novice teachers to guide student thinking using effective questions. This study examined how novice secondary science teachers’ understand the relationship between student thinking and teacher questioning. The sample was seven novice secondary science teachers’ enrolled in the University of Central Florida’s job embedded Resident Teacher Professional Preparation Program (RTP3 ). All participants received instruction and guided practice with the use of questions to elicit, probe, and challenge student ideas in the secondary science pedagogy class. Participants completed a questionnaire describing their …

Science Youth Action Research: Promoting Critical Science Literacy Through Relevance And Agency, Elizabeth Coleman

Dissertations

This three-article dissertation presents complementary perspectives on Science Youth Action Research (Sci-YAR), a K-12 curriculum designed to emphasize relevance and agency to promote youth's science learning. In Sci-YAR, youth conduct action research projects to better understand science-related issues in their lives, schools, or communities, while they simultaneously document, analyze, and reflect upon their own practices as researchers. The first article defines Sci-YAR and argues for its potential to enhance youth's participation as citizens in a democratic society. The second article details findings from a case study of youth engaged in Sci-YAR, describing how the curriculum enabled and constrained youth's identity …

Multilevel Analysis Of Fifth Grade Teacher Qualifications And Their Students' Science Achievement, Nigel Noll

ETD Archive

The No Child Left Behind Act mandated every student be taught by a highly qualified teacher (HQT). Criteria to determine if teachers meet the HQT mandate fail to account for differences in grade levels, subject areas, and student demographics. This study posited that the relationship between measures of teacher quality and student achievement vary according to contextual factors. Fifth grade is unique in that it marks students' transition from upper elementary to middle school grade levels thus, fifth grade may be classified as either an upper elementary grade or middle grade. This classification determines HQT requirements specifically, classification affects the …

Meaningful Encounters: Creating A Multi-Method Site For Interacting With Nonhuman Life Through Bioarts Praxis, Donna Franklin

Theses: Doctorates and Masters

This research advocates a multi-method approach to bioarts praxis, reflexively and critically questioning the contemporary contexts that frame our engagement with nonhuman life. In doing so, the research aims to generate further community engagement with nonhuman life and the environment, and engender critical discourse on the implications of developing biotechnologies.

Hegemonic institutions influence the way culture is produced and how information is constructed and understood. Habermas (1987) suggests that these institutions will inevitably influence the individual’s lifeworld as they shape lived experience through the process of systemic colonisation. I assert that this process also shapes how individuals engage with or …
