Abstract

The purpose of this research was to design a Visualization-based Learning Approach (VAL) in learning Engineering Drawing (ED) specifically for the topic auxiliary view (AV). The research comprises three phases, that is, (i) Phase I is to determine students’ levels of difficulties in ED topics, (ii) Phase II is to identify students’ cognitive visual levels and AV problem solving methods which is then used to develop the pattern of problem solving methods in ED among students of various cognitive visual levels; (iii) Phase III is the development of VAL. The fundamental theories used in this research are Wiley Visual Cognition Stage, Auxiliary View Problem Solving Approach and Visual Literacy. Both qualitative and quantitative approaches are used to collect the data. The research samples consist of 43 Engineering Drawing teachers in Phase I and 350 students in Phase II . The research instruments used for data collection include questionnaires, tests and interviews. Quantitative data were analyzed using SPSS while qualitative data were analyzed using triangulation method in single-case and cross-cases. Results were presented as percentages, frequencies, means and transcripts. The findings of Phase I showed that the topic of AV is one of the topics in Engineering Drawing with high level difficulty. Results of Phase II showed the descending order of students’ visual cognition levels from visual memory, visual perception to visualization. The results also showed that the students used a combination of principles of projections, imagination and sketching to solve Engineering Drawing problems. The evaluation of the effects of using Visualization-based Learning Approach will be conducted to enhance students learning ED especially for the topics requiring visualization skills.
