<![CDATA[This study aims to investigate the impact of interactive electronic worksheets combining three chemical representation levels on students’ critical thinking skills in learning voltaic cells. This research utilises an R&D (Research and Development) method featuring a one-group pretest-posttest design. The participants in this study were 12th-grade high school students. The tools used in this research included validation sheets, pretest-posttest assessments, and feedback questionnaires. Validation data indicated that the e-worksheets were suitable for testing, achieving a median score of ≥ 4. The pretest-posttest results were analysed using the N-Gain score, which fell within the range of 0.7 to 0.9. Additionally, a paired t-test was conducted using the Minitab software, yielding a p-value of less than 0.05, signifying a meaningful enhancement in students’ critical thinking skills. The feedback from students regarding this media resulted in a practicality rating of ≥ 61%. In summary, interactive e-worksheets based on the three levels of chemical representation have been demonstrated to improve students’ critical thinking skills.]]>
