  • In this study, visually impaired secondary students' conception of "changes of state of water" was explored. Science inquiry activity for students with visual impairments was implemented to 16 middle school students and 15 high school students from school for the blind. 14 of them were totally blind, 13 had low vision and the others were not identified. Inquiry activities were conducted by communicating with the researcher while students were individually exploring the molecular models of water and ice developed for the study. After the exploration, students were asked to explain the concept of changes of state of water with the model they explored. Opinion on the need and the usability of this kind of tactile model was also asked to them. All conversations were recorded, transcribed, and analyzed. As a result, students with visual impairments answered exactly about the materials used for the model and their numbers. However, they didn't know what the model stood for. They had experiences of learning molecule of water and changes of state of water, but it was a phenomenon and superficial understanding. Students got to understand the molecular structures of water and ice, and had a positive perception on the need and the usability of the model. Based on these results, educational implications were discussed.

  • This study was conducted to develop a plan for a large-scale implementation of the Girl Friendly Science Program based on the results of analysis and investigation of its current pilot implementation, Girl Friendly Science Program materials, which was first developed in 1999 with the support from Ministry of Gender Equality, consist of 1) five theme-based units that are specifically targeted individual students' unique ability, aptitude, and career choice, and 2) differentiated learning materials for 7th through 10th grade female students. All the materials are available at the homepage (http://tes.or.kr/gfsp.cgi) of 'Teachers for Exciting Science(the organization of science teachers in Seoul area)'. Since the materials are well organized by topic and grade level and presented in both Korean word process document and html format, anyone can easily access to the materials for their own instructional use. Ever since its launch the number of visitors to the homepage has been constantly increasing. The evaluation results of the current pilot implementation of the materials that targeted individual students' ability and aptitude showed that it scored high in terms of its alignment to the original purpose, content, level, and effectiveness to implement in classrooms. However, its evaluation scores were low in terms of the convenience for teachers to guide the materials, and its organization and operation. The results also showed a significant change in students' perception of science, and students' positive experiences of science through various interdisciplinary activities. On the other hand, the evaluation of students' experiences with the materials showed that students' assessment about an activity was largely depending on a success or failure of their experiences. Overall, students' evaluation of activities scores were low for simple activities such as cutting off or pasting papers. According to students' achievement test results, differences between pre and post test scores in the Affective Domain was statistically significant (p<0.05), but not in Inquiry Domain. Based on teachers observations, numerous schools where have run this program reported that students' abilities to cooperate, discuss, observe and reason with evidences were improved. In order to implement this program in a larger scale, it is critical to have a strong support of teachers and induce them to change their teaching strategy through building a community of teachers and developing ongoing teacher professional development programs. Finally, there still remain strong needs to develop more programs, and actively discover and train more domestic woman scientists and engineers and collaborate with them to develop more educational materials for girls in all ages.

  • The purpose of this study is to analyze how optics concepts and activities have changed according to the revision of the national science curriculum. For this purpose, the optics achievement standards presented in the middle-school science curriculum of the 7th curriculum, 2007 revised curriculum, 2009 revised curriculum, and 2015 revised curriculum, and the optics content presented in the textbooks developed for each curriculum, were compared and analyzed. The optics content is classified into four concepts: the process of viewing an object; light and color; reflection and refraction; and the image from a mirror and a lens. The main results are as follows: First, according to the revision of curriculum, some optics concepts have been added or removed. In particular, big changes have appeared in the concepts of "process of viewing the object", "dispersion", "reflection and refraction" and so on. Second, the content for 'image formation by a mirror and a lens' was gradually reduced, according to the revision of curriculum, and the level of activity was also adjusted. Third, attempts to present the content of textbooks in conjunction with the phenomena and tools that students can experience in everyday life have increased gradually. In addition, based on the analysis of the content of curriculum and textbooks, the implications for optics education have been discussed.
