Keywords:
Convex Lens, Pine-Zodiac, Ray DiagramsAbstract
This study was carried out due to the concern of the researchers after observing the students' poor performances in mastering the ray diagrams for convex lens involving various positions of objects and the impact on changes in the position of images, characteristics and examples of optical equipment. The objectives of the research are to increase students' performance in this topic, to attract students’ interest in learning a difficult topic, and to develop interesting and effective Teaching Aids. The study was conducted on 40 students in the second year of the Sijil Vokasional Malaysia (SVM) at Kolej Vokasional Seri Manjung. This study involved the technique of drawing convex lens ray diagrams using the Pine- Zodiac (PZ) Technique as well as the use of PZ model. Research methodology used is the Kemmis & McTaggart model (1988) through Pre and Post-test instruments, interviews and surveys. The PZ Technique is used as an intervention. Statistical analyses were performed using SPSS 27.0 software. Significant difference pre- and post- intervention were determined using T-Test while significant difference in groups were determined by Spearman Test for the Likert Scale, with significance accepted at p<0.05. The higher mean score after using the PZ technique which is -58.325. In conclusion, the PZ Technique is really beneficial for both students and teachers as students’ achievement can be enhanced, students’ confidence can be increased, and the Teaching Aids alternative. Hence, this technique can be developed through blended-learning involving face-to-face and virtual lesson in the future.
