<![CDATA[Practical difficulties often hinder students' understanding of simple electrical circuits. Confirmative practicums limit creativity as they do not provide opportunities for students to explore experiments independently. Furthermore, traditional practicums fail to accommodate diverse conceptual levels, including high and low electrical flow comprehension. To address these challenges, this study aimed to develop a virtual lab supplemented with an alternative solution worksheet for teaching simple electrical circuits to elementary school students. The research employed the Alessi & Trollip development model, encompassing three stages: planning, designing, and developing. Each stage involved continuous evaluations to ensure the quality of the developed product. Data collection methods included observations, interviews, and questionnaires, with validation performed by material and media experts. Data analysis utilized qualitative descriptive techniques to assess the product's effectiveness. The results indicated that the material validation test achieved an average score classified as "very good," with a percentage of 85.00%. Similarly, media validation results demonstrated an average percentage of 80.11%, also categorized as "very good." The implementation of the virtual lab showed significant improvements in students' understanding, as reflected in their test scores. The average pre-test score was 31.63, which increased substantially to an average post-test score of 70.51. These findings suggest that the virtual lab, combined with alternative solution worksheets, effectively enhances students' conceptual understanding and creativity in learning simple electrical circuits. This approach offers a promising alternative to traditional practicums for improving science education in elementary schools.]]>
