The Technological Pedagogical Content Knowledge (TPACK) Instrument in Zelkowski et al. (2013) is a self-efficacy survey that seeks to monitor and assess teachers' development of TPACK and seven interrelated knowedge domains. The measure is primarily aimed towards pre-service secondary mathematics teachers and can be used to “longitudinally study program effectiveness at TPACK development”, and to “conduct large-scale multi-institutional research studies” (Zelkowski, et al., 2013).
