Students perceive chemistry as a complex subject resulting in low academic performance. Education systems shall support students in bridging the gap between traditional learning and online set-up using technology-based materials. The Electronic Strategic Intervention Material (E-SIM) is a new learning method to help improve the learner’s performance in the least mastered competencies. This study focuses on determining how the E-SIM for “Ganyan Ang Bonding” (in English: Bonding Goes Like This) topic will improve the Grade 11 students’ knowledge about chemical bonding. The researchers used a one-group pretest-posttest control design. The population was pooled using simple random sampling and out of the randomly selected sections, twenty-two students were qualified after the voluntary response sampling. Pretest and posttest, which underwent validation, were given before and after the intervention respectively. The material was validated by experts prior to its utilization. The analysis showed a 0.01 normalized gain score, which is confirmed by the paired sample t-test with a result of -3.17 and p-value of 0.0023, hence presenting that there is a significant increase between the pretest and posttest scores. The student perception survey was used to further determine the efficiency of the material, which showed that the students perceived the E-SIM as an effective tool as review material.
