Abstract

Abstract. This study aims to develop a learning medium in the form of student worksheets based on the Microcomputer-Project Based Learning (MPjBL) model, to meet the needs of mechanics courses. The developed MPjBL-student worksheets is intended to be valid, practical, and effective in enhancing students^ mastery of mechanics concepts pre-service physics teacher students. The study was conducted using the Research and Development (R&D) method, following the Borg and Gall model. Validation of the MPjBL-student worksheets was carried out by four experts, including subject matter experts, media experts, and evaluation experts, using a questionnaire instrument, with data analyzed through Aiken^s V. Preliminary field testing was conducted to assess the attractiveness, usability, and effectiveness of the MPjBL-student worksheets through learning activities involving ten pre-service physics teacher students. The improvement in conceptual mastery was employing Normalizaed Gain (N-Gain) analysis. The results showed that, according to the experts, the developed MPjBL-student worksheets was categorized as highly valid. Based on the users^ responses, the MPjBL-student worksheets was found to be very interesting, very easy to use, and effective in improving both the mastery of mechanics concepts. The distribution of shifts in conceptual mastery for most students falls within the moderate to high categories.

Keywords: mechanics learning, MPjBL-student worksheets, project based learning.
