This study focuses on the impact of teachers’ teaching strategies on students’ motivation in Science, Technology, Engineering, and Mathematics (STEM) classrooms at Sekolah Kebangsaan (SK) Dato’ Ishak and SJK (C) Chung Cheng in Perak. The independent variable for this study is teaching strategies, and students’ motivation is the dependent variable. This study is focused on twelve respondents (teachers) in SK Dato’ Ishak and SJK (C) Chung Cheng, Perak, and employs a qualitative research approach. The interview was conducted via an online platform through Google Forms (open-ended questions). The Google Forms were distributed through E-mail to teachers in both schools with the permission of the school heads. Researchers received twelve responses, and the data were analysed using thematic analysis by identifying patterns and recurring themes based on the responses given by respondents. The findings show that teachers’ teaching strategies will impact students’ motivation in STEM classrooms. Based on the research, teachers focus on implementing cooperative learning (student-centered approach) and using technology during the teaching and learning process in STEM classrooms. It is a 21st-century teaching process that has a good impact on students’ motivation. The findings of this study underscore the importance of adopting thoughtful teaching strategies, particularly highlighting the benefits of student-centered approaches and positive reinforcement for enhancing student motivation and engagement.
