Video tutorial screencast and sketchup make (VTS-SUM) for low achievers in learning 3d geometry

Abstract

Students’ weaknesses in learning 3-Dimensional (3D) geometry are mostly associated with their low level of geometric thinking. Although a 3D software has been proposed as a manipulative learning tool, they had difficulties using it. Therefore, a suitable learning strategy should be designed to overcome the problems. The purpose of the study was to assess a learning strategy, known as Video Tutorial Screencast SketchUp Make (VTS-SUM), which integrates screencast techniques with a 3D software. VTS-SUM is a know-how video that assists students to visualize steps in drawing the orthogonal projections for 3D objects. A total of 180 students from a secondary school were involved in the study, conducted using a quantitative approach, where, a van Hiele Geometric Thinking (vHGT) test was employed to find out the level of students’ geometric thinking. The findings obtained showed that the majority of the students were at the Lowest Level (Level L1). As for usability test, a total of thirty students were selected from among those below this level. They were given some time to watch the video and perform hands-on activities using the software. A seven-point Likert scale questionnaire, comprising four constructs, namely, usefulness, ease of use, ease of learning and satisfaction, was used to measure the students’ perceptions of the usability test. The results obtained indicated that the students had positive perceptions towards the usage of VTS-SUM in their learning, thus accentuating its good potentials to enhance learning in mathematics.
