Teachers' perceptions of teaching science with technology-enhanced self-regulated learning strategies through the DECODE model

This study investigates the nuanced interplay between self-regulated learning (SRL) and technological pedagogical content knowledge (TPACK) among 192 Taiwanese voluntary pre-service and in-service teachers, seeking to understand how teachers perceive the integration of technology with SRL strategies in science education. The participants were recruited in workshops based on the DECODE model, which demonstrated a micro-unit of evolution incorporated in SRL strategies, involved them in co-reflected, and summarized what they had experienced in technology-enhanced environments. Participants self-reported measures of SRL and TPACK were subjected to path analysis. Results indicated that SRL positively influenced technological pedagogical knowledge (TPK) and technological content knowledge (TCK), subsequently fully mediating the relationship between SRL and TPACK; namely, TCK and TPK acted as mediatory factors. Furthermore, this study delved into teachers' perceptions of technology-enhanced instruction and SRL through their responses in workshops. We identified five main themes through thematic analysis. The findings highlighted the pivotal role of technology in cultivating interactive learning environments, offering real-time feedback, and integrating multimedia into teaching. Teachers' perceptions were expanded and refined after demonstrating a micro-unit with SRL strategies and subsequent reflective prompts. Participants acknowledged the imperative of teacher preparation in effectively leveraging technology and emphasized the crucial role of adaptive scaffolding in promoting SRL strategies. In summary, these findings present a viable path for augmenting teachers' TPACK through SRL and provides insights into teachers' perceptions of technology-enhanced SRL. The study has implication on the potential of the DECODE model and incorporation of SRL strategies for science educator's professional development of TPACK.
