Testing a TPACK-Based Technology Integration Observation Instrument
Thursday, March 10 4:00-4:30 PM
Teachers’ knowledge for technology integration – conceptualized as technological pedagogical content knowledge, or TPACK (Mishra & Koehler 2006) – is difficult to discern, much less assess. Given the complexity, situatedness and interdependence of the types of knowledge represented by the TPACK construct, well-triangulated ways to assess demonstrated technology integration knowledge are needed. In 2009, three of the authors created and tested a rubric that was found to be a valid and reliable instrument to assess the TPACK evident in teachers’ written lesson plans (Harris, Grandgenett & Hofer 2010). We have now also developed a TPACK-based observation rubric that testing has shown to be robust. The instrument’s interrater reliability coefficient (.802) was computed using both Intraclass Correlation and a percent score agreement (90.8%) procedure. Internal consistency (Cronbach’s Alpha) was .914. Test-retest reliability (score agreement) was 93.9%.
