Abstract: This study was carried out due to the concern of the researchers after observing the students' poor performance 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. The findings were analyzed using the method of finding mean and percentage. The findings showed an increment in students’ achievement after implementing PZ Technique in lesson as they applied it in the Final Assessment, whereby students achieving excellent results increased from 1% to 93%. There was also an increase in students' interest towards the topic which is considered challenging, and interesting Teaching Aids for the Teaching and using PZ Technique that showed a mean of 4.58, which is at a fun level as the question asked to students is whether they enjoy using the PZ Technique. 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. Keywords: Pine-Zodiac, ray diagrams, convex lens
