PINE-ZODIAC: Methods of Mastering Ray Diagrams for Convex Lens Among Students of Kolej Vokasional Seri Manjung
Keywords:
Pine-Zodiac, ray diagrams, convex lensAbstract
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
equipments. 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 analysed 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.
