University science teachers' technological pedagogical and content knowledge (TPACK) is crucial for effective teaching. Although there has been a plethora of studies investigating pre-service and in-service teachers' TPACK, few studies have examined university instructors' TPACK and university students' perceptions of instructors' TPACK. The main purpose of this study was to examine the TPACK questionnaire differences between university students' perceptions and instructors' self-perceptions, and assess differences in university physics instructors' TPACK according to gender, academic degrees and teaching experience in Taiwan. This study adopted and revised an instrument for measuring university students' perceptions of science instructors' TPACK. The sample was randomly selected from the physics instructors of universities in the northern, central, and southern regions of Taiwan. Exploratory factor analysis was conducted to examine the dimensions of the instrument. The results revealed that the TPACK questionnaire of university physics instructors' views were different from the university students' perceptions. University physics instructors' results indicated statistical significance in overall TPACK according to teaching experience. The research implications of this study are provided along with suggestions.
Technological Pedagogical and Content Knowledge (TPACK) has been gaining traction among educational researchers; however, studies documenting university students' perceptions of their teachers' TPACK remain limited. This study intends to investigate the professional development of two physics instructors through the lens of the TPACK framework. Moreover, this study spans an 18-week semester within both the contexts of Taiwan and China. Multiple data were collected and analyzed, including the pretest and posttest TPACK surveys, instructor interviews, in-class observations and students' feedback and opinions. The results revealed that John's instructional representations and strategies and technology integration and application scores increased significantly, as well as Mike's knowledge of students' understanding score showing a significant increase from the middle to the end of semester. John (Taiwan) emphasized life examples and the use of multimedia while Mike (China) chose to emphasize students' knowledge and evaluation. Such results showed different teaching characteristics in the two contexts. Implications and suggestions are put forward based on the results of this study.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
