This study at a large midwestern university evaluated the use of a web-based simulated classroom, simSchool, with pre-service and in-service special education students, to determine if use of the simulated classroom influences students' perceptions of inclusion and teacher preparation. The project used a nonequivalent comparison group, quasi-experimental design. The Effective Inclusion Instrument and Teacher Preparation Survey were used to gather research data. The primary purpose of this study was to examine the effectiveness of simSchool in improving participants' scores in teacher preparation and attitudes toward inclusion. Additionally, data were collected regarding the instructional delivery method of the simulation training, comparing face-to-face training sessions with watching online videos. Findings revealed that students who participated in the teaching simulation scored higher on the teacher preparation survey and valued simulations and computer games more.
