Development of a 4D Model-Based Computational Chemistry Practicum Guide: An Evaluation of Its Validity and Practicality

Abstrak

This study aims to develop a Computational Chemistry Practicum Guide using the 4D (Define, Design, Develop, Disseminate) model to evaluate its validity and practicality for Chemistry Education students. This research is a type of Research and Development (R&D) limited to the first three stages of the 4D model. The study involved three expert validators and 20 students of the Chemistry Education program at Khairun University. The data collection instruments included expert validation sheets and student response questionnaires. The data were analyzed using Aiken’s V for validity and percentage analysis for practicality. The results showed that the average Aiken’s V value was 0.892 (very high validity) and the practicality level was 81,56% (very practical). Thus, the developed Computational Chemistry Laboratory Guide is considered feasible and practical for supporting chemistry learning activities.
