The Relationship Between Middle Level School Science Programs And A Residential Environmental Learning Center, Ryan Mathew Walker

Graduate Theses and Dissertations

A multiple case study investigation examines the relationship between a residential environmental learning center and six schools that attend their program. Pre-experience interviews were conducted with teachers to gain understanding of how they integrate the residential experience with formal classroom instruction. On-site observations of teacher participation during the program provided insight into how they foster student learning during the experience. A student questionnaire was used to reveal students' perceptions of three areas of interest: 1) most meaningful aspects of the experience, 2) most confusing aspects of the experience and 3) topics they would like to know more about. These data …

Using The R Library Rpanel For Gui-Based Simulations In Introductory Statistics Courses, Ryan M. Allison

Statistics

As a student, I noticed that the statistical package R (http://www.r-project.org) would have several benefits of its usage in the classroom. One benefit to the package is its free and open-source nature. This would be a great benefit for instructors and students alike since it would be of no cost to use, unlike other statistical packages. Due to this, students could continue using the program after their statistical courses and into their professional careers. It would be good to expose students while they are in school to a tool that professionals use in industry. R also has powerful …

Teacher Certification And Student Achievement, Patricia Lewis Moss

Dissertations

The purpose of this mixed-method study was to determine if there is a significant difference between the achievement of students who are taught by traditionally prepared teachers and that of students who are taught by alternatively prepared teachers. The study further addressed the perspectives of both groups of teachers regarding selected dimensions of teaching.

The findings indicated that, overall, no significant difference existed in student achievement on MCT2 math scores for teachers who were alternatively prepared or traditionally prepared. However, there were significant differences in student achievement in grades 6 and 7 when examined by teacher preparation type. There was …

Team-Teaching Experiences Of A Mathematician And A Mathematics Teacher Educator: An Interpretative Phenomenological Case Study, Sarah K. Bleiler

USF Tampa Graduate Theses and Dissertations

In recent years, experts and organizations involved in mathematics education have emphasized the importance of collaboration between mathematicians and mathematics teacher educators as a means of improving the professional preparation of mathematics teachers. While several such collaborative endeavors have been documented in the extant literature, most research reports have focused on the products, rather than the process, of collaboration. The purpose of this interpretative phenomenological case study is to gain an understanding of the lived experiences of a mathematician and a mathematics teacher educator as they engaged in a team-teaching collaboration within the context of prospective secondary mathematics teacher preparation. …
