Latent Transition Analysis of Pre-service Teachers' Efficacy in Mathematics and Science

This study modeled changes in pre-service teacher efficacy in mathematics and science over the course of the final year of teacher preparation using latent transition analysis (LTA), a longitudinal form of analysis that builds on two modeling traditions (latent class analysis (LCA) and auto-regressive modeling). Data were collected using the STEBI-B, MTEBI-r, and the ABNTMS instruments. The findings suggest that LTA is a viable technique for use in teacher efficacy research. Teacher efficacy is modeled as a construct with two dimensions: personal teaching efficacy (PTE) and outcome expectancy (OE). Findings suggest that the mathematics and science teaching efficacy (PTE) of pre-service teachers is a multi-class phenomena. The analyses revealed a four-class model of PTE at the beginning and end of the final year of teacher training. Results indicate that when pre-service teachers transition between classes, they tend to move from a lower efficacy class into a higher efficacy class. In addition, the findings suggest that time-varying variables (attitudes and beliefs) and time-invariant variables (previous coursework, previous experiences, and teacher perceptions) are statistically significant predictors of efficacy class membership. Further, analyses suggest that the measures used to assess outcome expectancy are not suitable for LCA and LTA procedures.

Constructing Transformative Experiences Through Problem Posing in a High School English Research Project. (open access)

Constructing Transformative Experiences Through Problem Posing in a High School English Research Project.

This dissertation chronicles my search to engage high school English students in inquiry as part of a formal research process. The perspective of critical literacy theory is used to describe the four phases of the problem posing process in shaping student research and action. Grounded in Freire's approach and consistent with Dewey and others who advocate inquiry, action and relevance, Wink's process is built into the instructional plan described in this study. Because of the real-life context of the classroom and the complex social phenomena being considered, a case study methodology was utilized in which multiple sources of data converged to develop the themes. Data sources included the work and artifacts of ten students in a tenth grade English class during the spring semester of 2008. The analysis focuses on the supports, the constraints and the impact of problem posing on the high school research assignment. The analysis, findings, and conclusions contribute to the literature in three areas: audience, reflection and grading.
