In the typical high school chemistry curriculum, chemical bonding precedes the chemical reactions. This study has investigated the resequenced effect of learning chemical bonding when chemical reactions are introduced first among Grade 9 learners. A learning module with resequenced intervention in chemical bonding was developed and evaluated by students and teachers. This study assessed the formative scores and differences in proficiency levels between the control and experimental groups. The resequenced module was evaluated as very satisfactory by teachers. Although some respondents voiced negative preconceived notions about the subject, the majority of the evaluations were positive, agreeing with its effectiveness. Moreover, formative scores from the experimental group displayed a slightly higher overall satisfaction percentage (99.06%) compared to the control group (94.74%). Both groups demonstrated significant improvements in competency levels from pre-tests to post-tests; however, the experimental group has significantly higher scores (M = 49.3, SD = 19.4)  compared to the control group (M = 41.4, SD = 15.3), with a p value of 0.016 and a d value of 0.37. Furthermore, there was no significant association between competency levels and respondents' evaluations of the module, suggesting that baseline competency may be independent of attitudes or behaviours towards the module. Findings suggest that the resequenced learning module was successful in improving student learning outcomes. The module was well-received and led to significant gains in student competency. Hence, the intervention itself has resulted in a valuable tool for enhancing understanding of concepts in chemical bonding.
