Abstract: Conventional teaching and learning methods, along with memorization, lead to weak mastery of scientific process skills (SPS), resulting in students becoming passive, disinterested, and discouraged with SPS. Most of them struggle with mastering skills such as controlling variables and defining them operationally. Therefore, an action research study was conducted on 16 students in a school in Kuala Lumpur to improve these two SPS through the InKooNik intervention. InKooNik is a series of teaching and learning activities consisting of three experimental activities and worksheets related to these two SPS. This intervention incorporates the concepts of inquiry, cooperation, and mnemonics.
