Development of Learning Media using Model Based for Load and Failure Behavior of Precast Concrete Joints

Abstract

The objectives of this research were 1) to develop a learning material on the failure behavior of precast concrete joints 2) to evaluate the effectiveness of these learning materials, and 3) to study the satisfaction of using the learning materials. This preliminary experimental study employed a single-group pre- and post-test design. The research tools were physical concrete models, visual models, mathematical models, and a satisfaction assessment. The sample consisted of 25 third-year civil engineering undergraduates from Rajamangala University of Technology Srivijaya. The findings indicated: (1) high content of the pre- and post-tests, with Index of Item-Objective Congruence (IOC) values of 0.965; (2) a statistically significant (p < .05) improvement in post-test scores (36.2) compared to pre-test scores (13.2); (3) the model-based learning materials demonstrated an E1/E2 effectiveness ratio of 33.0/88.2 which is based on the assumption of only the E2 efficiency value because it is higher than 80, and (4) a high level of satisfaction with the learning materials, with mean scores ranging from 4.4 to 4.8, indicating good to very good satisfaction.
