The purpose of this study was to develop the Life Science I instruction programs using 3D modeling software to improve the students’ mental model and to investigate the effect of these programs. In order to develop the programs, the topics and 3D modeling software were selected, and lesson plan and worksheets were designed. The lessons were applied to 68 11th grade students, the mental model test was administrated before and after lessons, and the survey on students’ perception about these lessons was carried out after lessons. As a result, the Life Science I instruction programs using 3D modeling software have 4 topics; ‘structure of brain’, ‘structure of spinal cord and spinal nerve’, ‘structure of chromosomes’, and ‘mitosis’. ‘TinkerCAD’ was selected as 3D modeling software. And class activities were composed of the steps of ‘model generation’, ‘model evaluation’, and ‘model modification’ based on the GEM cycle, and the step of ‘expression of the result of observation and description of the change of mental model’. In the result of mental model test, the posttest score was higher than the pretest score(p<.001), and the students expressed the structure of brain, spinal cord, spinal nerve, and chromosome more elaborately. Most students replied to survey that they were interested and participated actively in these classes, willing to participate these classes continuously and got some help to study these topics. Based on these results, the Life ScienceⅠ instruction programs using 3D modeling software are effective in improving high school students’ mental model, and the students had positive thoughts about these programs. It is necessary to conduct research on how to use 3D modeling software on various topics of Life ScienceⅠ.
