This study was focused on the effect of pre-service teaching utilizing a co-teaching model on student achievement at an elementary school in a large, urban school district in central Florida. The contribution of university student teachers (i.e., interns) to elementary school achievement was investigated. Specifically explored was the difference between student achievement scores in classes with interns who participated in a co-teaching model and interns in classes that did not employ any structured approach to intern teaching. The researcher compared seven classes that employed co-teaching, where the university intern teacher and master teacher remained in the class conducting instruction, to seven classes that had a more traditional approach to the intern teaching. The co-teaching intern model did not exert a significant effect, either positive or negative, on student achievement. Also investigated was the effect of an intern, utilizing any model, on student achievement scores, when compared to similar classes without the presence of an intern. The study utilized 14 classes with interns and 13 classes without interns; each group had populations of approximately 285 students. The presence of an intern did not exert a significant effect, either positive or negative, on student achievement. However, the data indicated that the presence of an intern could positively influence mathematics scores. Additionally, the impact of teacher quality and socio-economic status on student achievement in reading and mathematics were explored. The data revealed the value of the individual teacher significantly affected student success in reading and mathematics. In reading, socio-economic status also significantly affected student achievement.

The purpose of this study is to determine the impact on student achievement of elementary school teachers who participated in professional development in the content area of mathematics. Teachers participated in professional development courses and have accumulated a range from three to eighteen total credits from the summers of 1998 through 2007. The impact is measured by student achievement data collected on standardized tests.
