Analysis of College Students’ Misconception on Geometrical Optics

Abstract

This research aims to analyze college students' misconception on optical concept. Participants were 36 college students of sixth semester from one intact class. College students' misconception of geometrical optics were measured by a three-tier misconception test. From the data collected we were determined the students' misconceptions profile that find students have misconceptions in each sub-chapter. Then from data analysis we found that: (1) percentage of first tier true answer is higher than percentage of second tier true answer for the whole class, but opposite for all students who suffer misconception (2) there is a significant opposite/negative correlation between students' misconception and the score they get (3) there is no significant correlation between students' score and degree of confidence for their answer to the problem.

Level of Students Conceptual Understanding and Resource Theory View: Geometric Optics

“…University students still have many misconceptions on the topic of Geometric Optics (Admoko et al, 2018). A study conducted by Aydin (Aydin, 2012) also obtained the results of misconceptions on the concept of reflection and refraction of light, where students assume that to be able to see objects on a flat mirror, the light source must shine on the mirror, the mirror and the object must be illuminated so that the object can be seen.…”
