The Effects of Infusion Approach in Engineering Drawing to the Critical Thinking Dispositions Among Technical Students

Teaching engineering drawings that focus only on the mastery of concepts and techniques without training students to manipulate and integrate the concepts and techniques learned preventing the application of critical thinking through this subject. Therefore, a study that determines the teaching method in applying and cultivating critical thinking disposition its effect is required. The two teaching approaches used were the conventional approach for the control group and the compounding approach for the treatment group. A quasi-experimental study with a nonequivalent control group design was carried out for 8 weeks on study groups selected from two different Technical Matriculation Colleges. A total of 31 students were selected for the control group and a total of 29 students were chosen for the treatment group in the sample study. A pretest, followed by an intervention for 8 weeks were carried out. After the intervention, a posttest was carried out on the control and treatment groups. The results of the pretest and posttest of the control group and treatment group were then compared and evaluated. Three instruments was used in the pretest and posttest is Malaysia Critical Thinking Instrument (MACTI). The pretest showed that there was no significant difference in the critical thinking dispositions of the control and treatment groups. However, the results of the posttest showed that the critical thinking dispositions of the treatment group were significantly higher than the control group.
