This study was designed to investigate the effect of a dynamic geometry learning environment on performance in the context of similarity tasks. The study population consisted of 52 preservice elementary teachers attending a southeastern American university and enrolled on three sections of a mathematics methods course in the College of Education.

520 $a This study was designed to investigate the effect of a dynamic geometry learning environment on performance in the context of similarity tasks. The study population consisted of 52 preservice elementary teachers attending a southeastern American university and enrolled on three sections of a mathematics methods course in the College of Education.
520 $a The design of the study was a pretest-posttest control group design with random assignment. Participants were randomly assigned to two groups within each course section. The timeline consisted of the pretest, three sessions, and the posttest. Sessions for the control group were held in the traditional mathematics laboratory and involved use of manipulatives, ruler, and protractor; the sessions for the experimental group were held in a computer laboratory on campus and involved use of the dynamic geometric construction software Geometer's Sketchpad (Jackiw, 1995).
520 $a To analyze the data collected during the study, analysis of covariance (ANCOVA) was conducted. The research instrument served as the covariate to statistically analyze hypotheses related to the first question. For the second question, prior mathematical knowledge, as measured by a standardized achievement test, served to adjust for initial differences in the two treatment groups.
520 $a Based on the analyses, there exists supportive evidence that the difference in learning environment between the two treatment groups had a significant effect upon performance on similarity tasks as measured by the research instrument. Fundamentally, the participants in the experimental group outperformed the participants in the control group even though initial variability was taken into consideration.
520 $a In addition to the quantitative statistical component, written reflections were collected from all participants at the end of each and every session. The purpose of this exercise was to gain further insight regarding the preservice elementary teachers' perspective of the instructional environment and to ascertain what had been learned during the session.
