This study utilized KAPLA assembling courses for 4 preservice preschool teachers and caregivers in order to apply computational thinking. Some instructional reflection and the course suggestion via action research method were discussed towards the pre-service STEAM education. The KAPLA course in this study was composed of 3-step processes for the preservice students to draw, assemble and share based on STEAM learning. Students not only used scientific knowledge, mathematical knowledge and technical tools but also used technology to design, solve problems, and make products. Besides, the instructor also provided types of scaffolding for the students to assemble KAPLA, such as oral questioning, demonstration and icon representation according to Synergistic scaffolds model (Tabak, 2005). Finally, after the students built up KAPLA topics of ‘traffic tools’, ‘department stores’ and ‘animals’ via different scaffoldings, the field notes and the interview transcripts during the assembling activities were analysed to explore the practice of computational thinking. In the end of the research, the researchers tried to propose the scaffolding model of KAPLA assembling for the procedure of imagination, decomposition, and pattern recognition.
