There are difficulties for first-year chemistry students to adapt to chemistry laboratory activities due to their lack of experience in their schools. As a result, it affects their confidence and also their safety awareness in the laboratory. One of the very basic required skills in a chemistry laboratory is undertaking titration. This multi-year study aims to design and develop chemistry pre-laboratory demonstration videos to make students familiar with the required laboratory skills before they start laboratory activities. The data were collected by paper-based and online questionnaires, observation, and inverview. According to the evaluation by users and experts, the usability and feasibility of the videos were categorized as very high. Moreover, corrections and suggestions were implemented to improve the quality of the videos.
