In Search For Instructional Techniques To Maximize The Use Of Germane Cognitive Resources: A Case Of Teaching Complex Tasks In Physics, Yekaterina Sliva

STEMPS Theses & Dissertations

The purpose of this study was to introduce an instructional technique for teaching complex tasks in physics, test its effectiveness and efficiency, and understand cognitive processes taking place in learners' minds while they are exposed to this technique. The study was based primarily on cognitive load theory (CLT). CLT determines the amount of total cognitive load imposed on a learner by a learning task as combined intrinsic (invested in comprehending task complexity) and extraneous (wasteful) cognitive load. Working memory resources associated with intrinsic cognitive load are defined as germane resources caused by element interactivity that lead to learning, in contrast …

Infusing Problem-Based Learning (Pbl) Into Science Methods Courses Across Virginia, K. R. Thomas, P. L. Horne, S. M. Donnelly, C. T. Berube

Journal of Mathematics and Science: Collaborative Explorations

This article outlines the results of a collaborative study of the effects of infusing problem-based learning (PBL) into K-12 science methods courses across four universities in Virginia. Changes in pre-service teachers' attitudes surrounding science teaching were measured before and after completing a science methods course in which they experienced PBL first-hand as participants, and then practiced designing their own PBL units for use in their future classrooms. The results indicate that exposure to PBL enhances pre-service teachers' knowledge of inquiry methods and self-efficacy in teaching science.

Grappling With Issues Of Learning Science From Everyday Experiences: An Illustrative Case Study, A.-L. Tan, M. Kim, F. Talaue

Journal of Mathematics and Science: Collaborative Explorations

There are different perceptions among researchers with regard to the infusion of everyday experience in the teaching of science: 1) it hinders the learning of science concepts; or, 2) it increases the participation and motivation of students in science learning. This article attempts to contemplate those different perspectives of everyday knowledge in science classrooms by using everyday contexts to teach grade 3 science in Singapore. In this study, two groups of grade 3 students were presented with a scenario that required them to apply the concept of properties of materials to design a shoe. Subsequently, the transcripts of classroom discussions …

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

College of Graduate Studies: Theses & 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 …

The Cultural Studies Of Science Education, Karen D. Chassereau

College of Graduate Studies: Theses & Dissertations

In an age of accountability, the demands and constraints placed on science teachers seem insurmountable. Teachers are challenged to provide students with authentic scientific experiences, yet the need to prepare students for high-stakes tests remains. The problem of attrition and job stress in the field of science teaching is growing. As pressures rise, it becomes necessary to understand what the culture of science education is like from the perspective of the science teacher. This study sought to define the culture of science education and determine how this culture informs teacher practice in the secondary science classroom. This qualitative case study …

Inquiry, Efficacy, And Science Education, Heather Christa Scott

College of Graduate Studies: Theses & 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 …
