Reimagining chemistry lessons through the BrainSTEMTA module for teaching the acid-base topic

Abstract

The topic of acid-base is one of the most challenging topics in chemistry that contains many abstract and complex concepts. To address the persistent challenge, the Whole Brain STEM Teaching Approach (BRAINSTEMTA) Module is systematically developed using the ADDIE instructional design model and incorporates seven Whole Brain Teaching (WBT) strategies: Class-Yes, Five Classroom Rules, Teach-Okay, The Scoreboard, Hand and Eyes, Switch, and Mirror. The STEM-based approach is embedded in alignment with the STEM Teaching and Learning (T&L) Framework introduced by the Ministry of Education Malaysia. BRAINSTEMTA Module is evaluated and validated by 12 experts based on five criteria: (1) effectiveness of WBT strategies, (2) quality of STEM integration, (3) suitability for students, (4) potential to enhance achievement in the acid-base topic, and (5) potential to enhance scientific creativity in the acid-base topic. The quantitative data are analysed using the Content Validity Index (CVI). The results indicated that the value of CVI for the scale (S-CVI/Ave) is 1.00 and is within the accepted range. The scores highlighted BRAINSTEMTA Module strengths in enhancing achievement and scientific creativity in the acid-base topic. These findings also advocated the module’s quality and potential for classroom implementation and future empirical testing.
