This study aimed to develop the STREAM (Science-Technology-Religion-Engineering-Art and Mathematics) teaching model for enhancing grade 8 students' creative and engineering design process skills. The innovative STREAM teaching model consisted six common teaching steps: a) Introduce the STREAM situation; b) Identify the targeted problem; c) Explore and plan to solve the problem; d) Solve the problem and integrate Art; e) Present creatively; and f) Summarize, apply and integrate with moral. Five STREAM lesson plans were designed for teaching the Motion topic. The quality of STREAM lesson plans was established by five experts. After that, the STREAM lesson plans were experimented with 39 Grade 8 students in the first semester of the 2021 academic year at one secondary school located in Songkhla province, Thailand. The research instruments included the Learning Achievement Test and the Engineering Design Process Test. The paired-samples t-test was used to analyze the differences of students' learning achievement and engineering design process skills at the prior and after the STREAM lessons in Motion. The results showed that the STREAM teaching model promoted higher learning achievement and engineering design process skills. The implications of the STREAM for teaching science are finally discussed.
