ABSTRACT
Laboratory work is the core of learning chemistry. Research has shown that students who are well prepared for laboratory classes and possess a high level of competency in laboratory skills are more likely to gain the maximum possible benefit. This development uses quantitative analysis by adapting the Kemp Model as an instructional design model. The video skills developed are how to use a thermometer, how to smell gas, how to make a standard solution from the stock solution, and how to make a standard solution from a solid. The results of the feasibility percentage, based on material and language expert tests, media expert tests and students’ evaluations, are 92.27%, 91.45%, and mean 3.79 (SD = 0.463) respectively. The research is conducted in a chemistry education program, which is aimed at the freshmen who take the chemistry practicum I course. It is hoped that using a facilitated video in the pre-laboratory phase can be an aid to delivering prior knowledge, reducing the number of potential mistakes in laboratory skills and undertaking the practical lab work effectively.
