A Proposed Teacher Professional Development Program for Promoting Adult Teacher's TPACK in STEM Education

In the context of Teacher Professional Development (TPD), there is a call for a specific and effective professional development program to improve teachers' essential teaching knowledge and facilitate the acquisition of new sets of skills to succeed in technology-enhanced learning. As such, Technological Pedagogical and Content Knowledge (TPACK) framework has been established in this century and played an important role in professional development transformation for teachers, who are currently adult learners. To promote the adult learner's professional development, this research intended to develop a teacher professional development program following the adult learning principles called "andragogy" that particularly addressed TPACK of integrated science, technology, engineering, and mathematics (SIEM) education. For the intervention, a personalized learning system has been strategically created and employed in the proposed TPD program to facilitate individual professional training needs for adult science teachers in Khon Kaen University Smart Learning Academy (KKU-SLA) project. The main finding indicated that the proposed TPD program could enhance science teachers' TPACK of integrated SIEM education significantly, and this implied an innovative TPACK professional development intervention to transform teacher's essential teaching knowledge for today's school science education.
