Evaluation Reports
During its first funding cycle (2001-2006), IRIS sought to gauge the effectiveness of our resources and materials by conducting, facilitating, and supporting small studies. The purpose of these studies was to determine whether the use of IRIS Modules improved the learning outcomes of college students enrolled in coursework leading to initial licensure or of practicing educators participating in PD activities.
- Learning Outcomes of Factual Knowledge: A Comparison of module and No Module Conditions (PDF)
During the 2004–2005 academic year, a study of the learning outcomes associated with the use of an IRIS Module was conducted at a large urban campus with a diverse student body.
- Gains in Factual and Applied Knowledge: College Students Using IRIS Modules Assigned as Homework or in Class (PDF)
During the 2005–2006 academic year, the impact of IRIS Modules on student learning was conducted to examine how factors related to instructor application of the principles of the How People Learn theory (HPL) affect student learning.
- Online Learning and Teacher Education: Knowledge Acquisition, Application Skills, and Reported Confidence (PDF)
A pair of studies found that the performance of college students improved significantly after their use of free, online instructional modules produced by the IRIS Center.
