Purpose: The purpose of this study was to analyze the concept of vision in optometric point of view described in 7th science curriculum and 48 science textbooks for elementary, middle and high schools in Korea.
Methods: Literature analysis method was used for the analysis, which is within the category of qualitative study.
Results: There were duplicative explanations of refractive error correction by convex and concave lenses at the Unit ‘Light’ in 7th grade and at the Unit ‘Stimulus and Response’ in 8th grade textbooks. Although there was no problem in a curriculum at the Unit ‘Light’, it was a conceptual leap for teaching principles of refractive error correction using eye glasses. There were difficulties in understanding the mechanisms of light and shade control of iris and near and distance control of ciliary muscle because of the oversimplified explanation. At the Unit ‘Mirror and Lens’ for 7th grade, it was not proper to explain the principles of refractive error correction right after learning convergence and divergence of light. Furthermore, the reason of refractive error was not consistent with the analysis of principles of refractive errors and their correction. Some textbooks explained the level of concept in reverse order. There were vague explanations at 5th grade textbooks about focal distance and at 7th and 8th grade textbooks about formation process of retinal image. Also, there was an oversimplified explanation of forming image as if it were a pinhole camera. The reason of refractive errors of myopia and hyperopia was inconsistent with explaining the principles of refractive error correction using eye glasses between Physics I and Biology I for 7th, 8th, 10th, and 11th grade. Lastly, there was an oversimplification in describing the mechanisms of light and shade control of iris and near and distance control of ciliary muscle. It only explained the role of a transparent cornea as a route of light regardless of its power.
Conclusion: It is needed to keep the appropriateness and connectedness of learning concept through conferences and examinations from the beginning stage of textbook development. Because it is important to connect Physics with Biology in explaining the concept of optometry in science textbooks.
