The aim of this study is to develop a valid and reliable Technological Formation Scale to measure Technological Knowledge (TK) and Technological Pedagogical Knowledge (TPK) which are main components of Technological Pedagogical Content Knowledge (TPACK). Technology seems to have an important place in teacher training and education. It is seen that only Pedagogical Content Knowledge (PCK) is not sufficient today. Therefore, the measurement tools including 21st century requirements which are the information and communication technologies skills, production and productive thinking are needed. Measuring technological and technological pedagogical knowledge of the teachers and teacher candidates is able to be possible by means of this measurement tool. Another aim of this study is to present a measurement tool within the TPACK framework, which is based on productivity for the researchers. The components of Technological Knowledge (TK) and Technological Pedagogical Knowledge (TPK) involve the productive thinking in this scale. Thus, it is aimed to obtain real-like results. The participants were 756 teachers and and teacher
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.
