Testing An Instrument Using Structured Interviews To Assess Experienced Teachers’ Tpack, Judith B. Harris, Neal Grandgenett, Mark Hofer

In 2010, the authors developed, tested, and released a reliable and valid instrument that can be used to assess the quality of inexperienced teachers’ TPACK by examining their detailed written lesson plans. In the current study, the same instrument was tested to see if it could be used to assess the TPACK evident in experienced teachers’ planning in the form of spoken responses to semi-structured interview questions. Interrater reliability was computed using both Intraclass Correlation (.870) and a score agreement (93.6%) procedure. Internal consistency (using Cronbach’s Alpha) was .895. Test-retest reliability (score agreement) was 100%. Taken together, these results demonstrate …

Although there is ever-increasing emphasis on integrating technology in teaching, there are few well-tested and refined assessments to measure the quality of this integration. The few measures that are available tend to favor constructivist approaches to teaching, and thus do not accurately assess the quality of technology integration across a range of different teaching approaches. We have developed a more “pedagogically inclusive” instrument that reflects key TPACK concepts and that has proven to be both reliable and valid in two successive rounds of testing. The instrument’s interrater reliability coefficient (.857) was computed using both Intraclass Correlation and a score agreement …

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 …
