Chemistry Graduate Teaching Assistants' Experiences In Academic Laboratories And Development Of A Teaching Self-Image, Todd Adam Gatlin
Chemistry Graduate Teaching Assistants' Experiences In Academic Laboratories And Development Of A Teaching Self-Image, Todd Adam Gatlin
USF Tampa Graduate Theses and Dissertations
Graduate teaching assistants (GTAs) play a prominent role in chemistry laboratory instruction at research based universities. They teach almost all undergraduate chemistry laboratory courses. However, their role in laboratory instruction has often been overlooked in educational research. Interest in chemistry GTAs has been placed on training and their perceived expectations, but less attention has been paid to their experiences or their potential benefits from teaching.
This work was designed to investigate GTAs' experiences in and benefits from laboratory instructional environments. This dissertation includes three related studies on GTAs' experiences teaching in general chemistry laboratories. Qualitative methods were used for each …
Student Identity Considerations And Implications Associated With Socioscientific Issues Instruction, Mitchel James Ruzek
Student Identity Considerations And Implications Associated With Socioscientific Issues Instruction, Mitchel James Ruzek
USF Tampa Graduate Theses and Dissertations
The purpose of this investigation was to explore how aspects of identity, perceived levels of controversy, and the strength of a student's attachment to their controversial identity relate to conceptual understanding and knowledge acquisition during socioscientific issues (SSI) based instruction in a biology classroom. The knowledge gained from this study will have the capacity to enhance our understanding of the role that attachment to identity plays during SSI negotiation. Additionally, insight was gained into the role played by aspects of identity in conceptual understanding of scientifically controversial topics during SSI based instruction.
This study contributed to the existing knowledge base …
The Effect Of Teachers' Epistemological Beliefs On Practice, Milton David Huling
The Effect Of Teachers' Epistemological Beliefs On Practice, Milton David Huling
USF Tampa Graduate Theses and Dissertations
Unfortunately, for the most part, teachers do not teach the Nature of Science (NOS). Even when teachers have adequate NOS knowledge, their knowledge still does not make its way into practice. While there are various reasons for this happening, this study has isolated other, more typical, constraints to teaching in order to look more closely at the influence of personal epistemological beliefs, understandings of NOS, and their effects on practice. In an effort to minimize typical constraints of time for the teaching of NOS, a sixth grade physical science course was chosen as a way to minimize this constraint. Within …
