Abstract:

“The implementation of effective professional development courses for K-12 teachers on computational thinking (CT) in relation to programming remains a challenge. There is a lack of high-quality empirical research on teacher development in CT in relation to programming. This study addressed that situation by providing empirical evidence of the design and evaluation of such a teacher development program in primary schools. Seventy-six in-service teachers participated in a program comprising two 39-h courses. One course focused on the fundamental subject knowledge of programming for CT development together with pedagogy. The other focused on the development of advanced knowledge while providing opportunities to practice teaching in the classroom and to reflect on the practice. The results indicate that the participants developed a better understanding of CT concepts and practices and improved in three of the four content knowledge related dimensions of technological pedagogical content knowledge (TPACK) across the two courses. The three dimensions were content knowledge of programming for CT development, technological content knowledge of the use of block-based programming environments for programming for CT development, and use of the environment to teach programming for CT development with the appropriate pedagogy in context. Analysis of the participants’ self-reported reflections suggested that the two courses and the teaching experience acquired during the prolonged second course were the two main sources of improvement. This study demonstrates the importance of providing an effective teacher development program with a focus on CT concepts and practices. The program offers teachers a sustained period in which to practice in the classroom and reflect on their teaching while developing their capacity to implement CT in relation to programming. • A teacher development program for CT in relation to programming was designed and evaluated. • Teachers’ CT concepts and practices improved consistently in the program. • In-service teachers attended the program and improved in all content-knowledge related TPACK dimensions. • A sustained period of active participation in programming activities was essential. • Opportunities to reflect on pedagogy in practicing CT in programming activities was important.”
