Investigating The Impact Of A Preservice Program On Beliefs About Science Teaching And Learning, Christopher Scott Soldat Dec 2009

Investigating The Impact Of A Preservice Program On Beliefs About Science Teaching And Learning, Christopher Scott Soldat

Theses and Dissertations

There has been much attention about improving the skills and abilities of students in Science. One critical factor is the quality of teacher education programs for preparing science teachers. There has been little research and much debate about what constitutes an effective science teacher education program. Teacher beliefs are thought to be important factors which influence how science teachers teach. This is a three year longitudinal study which explores changes in twelve teachers using a mixed method design. Semi-structured interviews were used to explore the beliefs about teaching, learning, and the Nature of Science. Four cohorts of teachers represented the ...


Student Perceptions About Learning Anatomy, Andrew John Notebaert Jul 2009

Student Perceptions About Learning Anatomy, Andrew John Notebaert

Theses and Dissertations

This research study was conducted to examine student perceptions about learning anatomy and to explore how these perceptions shape the learning experience. This study utilized a mixed-methods design in order to better understand how students approach learning anatomy. Two sets of data were collected at two time periods; one at the beginning and one at the end of the academic semester. Data consisted of results from a survey instrument that contained open-ended questions and a questionnaire and individual student interviews. The questionnaire scored students on a surface approach to learning (relying on rote memorization and knowing factual information) scale and ...


The Impact Of Embedding Multiple Modes Of Representation On Student Construction Of Chemistry Knowledge, Mark Andrew Mcdermott May 2009

The Impact Of Embedding Multiple Modes Of Representation On Student Construction Of Chemistry Knowledge, Mark Andrew Mcdermott

Theses and Dissertations

This study was designed to examine the impact of embedding multiple modes of representing science information on student conceptual understanding in science. Multiple representations refer to utilizing charts, graphs, diagrams, and other types of representations to communicate scientific information. This study investigated the impact of encouraging students to embed or integrate the multiple modes with text in end of unit writing-to-learn activities. A quasi-experimental design in which four separate sites consisting of intact chemistry classes taught by a separate teacher at each site was utilized. At each site, approximately half of the classes were designated treatment classes and students in ...
