Cross-Grade Comparison of Students' Conceptual Understanding with Lenses in Geometric Optics
Tural, G.
Science Education International, v26 n3 p325-343 2015
Students commonly find the field of physics difficult. Therefore, they generally have learning problems. One of the subjects with which they have difficulties is optics within a physics discipline. This study aims to determine students' conceptual understanding levels at different education levels relating to lenses in geometric optics. A cross-sectional design is used in the study. Participants in the study include one hundred and seventy-seven students at three different education levels from primary and secondary schools, and higher education. Seven open-ended questions, examining participants' conceptual understanding levels in relation to lenses, act as the data collection instrument. It is determined that students hold misconceptions such as, "convex lenses diverge light rays", "concave lenses converge light rays", "a right-side-up image replaces the previously observed inverted image, when a convex lens is removed," "myopia is corrected via convex lens," and "hyperopia is corrected via concave lens." The results show that students from all groups (primary and secondary schools, and higher education) have a lack of knowledge and experience conceptual problems about lenses, although they learned this subject in school.
