Practical instructions in the design adopted a closed practicum/experimental model. The results of expert validation which include aspects of the feasibility of content, presentation, linguistic components, and implementation indicated that the practicum instructions developed were estimated valid with an average score of 4.03 and were suitable for use. On the other hand, the results of the practicality test consisting of components of attractiveness, ease of use, and the benefits of the developed practicum instructions were also considered practical with an average score of 3.93. Moreover, the results of the effectiveness test on the practicum instructions showed that this development product was considered effective for increasing student interest (high category). Thus, it can be concluded that this video tracking-based practicum guide product is valid, practical, effective to be used as a practicum guide, and is able to increase student interest. Keywords: Practical Instructions; video tracking; student interest.
