Detailed, concise techniques videos designed in accordance with principles of multimedia learning aid student learning and utilization of new techniques in laboratory courses. In this work, a technique video for thin layer chromatography was developed and its impact on laboratory courses in both Organic and General Chemistry were studied. Additionally, to assess the physical aptitudes of the students, and to ensure experimental and control similarities, a novel hand-steadiness test was developed from an Operation Rescue Kit board game. The test was found to be both reliable and valid with p values of 0.007 and 0.012 respectively. The impact of manual dexterity on student laboratory performance was found to be statistically insignificant. The technique video was found to improve general chemistry student performance in accuracy, time, and amount of waste.
