Table 2 Organization of this project’s research questions and participation by 287 observed instructors
Research Questions | RQ1: What are the effects of teaching with ITG on the use of Student-Centered instructional strategies? | RQ2: Can anyone, regardless of their level of participation with ITG, teach with ITG materials and have a student-centered class? | RQ3: Do different instructors using the same ITG materials teach with similar levels of reform? |
|---|---|---|---|
Participant types (see text for definitions) | a. All observations (n = 345 b. Paired instructors (observed when teaching with and without ITG), n = 33 | All paired instructors (materials developers, mentored users, unmentored users) | All ITG users (materials developers, mentored users, unmentored users) |
Analysis | a. Welch’s unequal variance t test comparing scores of observations with ITG vs. scores of observations without ITG b. Two-tailed t test | Two-way mixed ANOVA compares RTOP scores across three participation categories | Comparison of RTOP scores for ITG units taught by more than one observed instructor |
