Model-Based Teaching and Learning: An Experiential Research of Teaching Engineering Drawing for First Year Engineering Students

Abstract

Technology plays a major role in the easement of teaching and learning in engineering education. Novel techniques adopted in the recent days, have resulted in a huge success on the part of educators. These techniques create a great difference in the instructional delivery, with real-time impact on the understanding and learning of students. In this context, Model Based Teaching and Learning (MBTL) is identified as one such resourceful method to teach certain educational concepts which require imagination. Use of models within the pedagogy of engineering education promotes meta cognitive thinking skills of students. The purpose of this research was to examine the advantages of adopting model – based teaching and learning for the course, Engineering Drawing for first year engineering students. A class of 120 Engineering students during the second semester participated in the research. The students were randomly grouped into two groups of each 60 in order to receive different treatments. The first group was identified as the Control group (CG) which was taught concepts of Engineering Drawing using traditional lecture method, while the second group, the Experimental Group (EG) was facilitated with models related to projection of lines and orthographic projections. The results revealed that using models had a significant impact on the academic achievement of the students. Based on their performance in the continuous assessment, it was concluded that models were very helpful in improving the marks, and also played an effective role in the comprehension of concepts.
