  • In this study, we investigated elementary school teachers' and students' perceptions of the reading materials in science textbooks. Participants were 181 teachers from 23 elementary schools who were teaching science and 643 third- to sixth-grade students from 12 elementary schools. A questionnaire for teachers consisted of 18 items and a questionnaire for students consisted of 11 items about their perceptions of the reading materials in science textbooks. Nine to twelve items, according to grades, examining the actual uses of each reading material in science textbooks were also included to both questionnaires. The results indicated that teachers have positive perceptions about reading materials and frequently use them in case of needs for supplement and/or enrichment of science learning. Novice teachers were found to have less positive perceptions about reading materials than expert teachers. Over 70 percent of students responded that they read all reading materials. Fifth- and sixth-grade students were tended to have less positive perceptions about reading materials than third-grade students. Finally, students tended to have more positive perceptions about reading materials than their teachers.

  • The purpose of this study is to develop a science writing teaching strategy, and to apply it to the fourth-graders in elementary science classes. We examined its effect on their motivation, attitude, and understanding of science concept. For the research fourth grade children were grouped into three classes: an experimental class A of 27 children, an experimental class B of 24 and a comparative class of 27. All of them are from H elementary school in Seoul, Korea. Experimental class A learned science writing with a newly developed strategy while experimental class B learned science writing in a traditional method. Comparative class did not learn science writing. As a result, class A showed positive changes on students' science motivation, attitude, and understanding of science concept. In addition, class B with even one science writing task for a chapter had higher achievement in the understanding of science concept than the comparative class had.

  • In this study, the types of inquiry activities in the $5^{th}$ & $6^{th}$ grade science textbooks according to the 2015 revised science national curriculum were analyzed and compared according to grade level and science area. Science textbooks for elementary school $5^{th}$ & $6^{th}$ graders contain quite diverse types of inquiry activities, which are student-centered inquiry activities. There were comparatively higher proportions of inquiry types such as experiment & observation and simulation, but relatively lower of inquiry types of investigation-discourse & presentation, discussion, expression. Elementary science textbooks are expected to cultivate science key competencies for elementary school students. Considering the science area, the motion & energy, substances, earth & space, and integration areas had the most experiment & observation among activity types, while the life area had the most simulation activities. Even in some area of the 6th grade science textbook, there was little or no data interpretation, discussion, and simulation activities. In order to achieve the goal of elementary science education, science textbooks should be developed considering the revision of future elementary science curriculum.

  • In this study, we analyzed the problems of grade 3~4 science textbooks developed for the 2007 revised national curriculum raised by elementary school teachers. 53 elementary school teachers were selected and asked to complete the open questionnaire to find out the problems they experienced or perceived when they taught the corresponding unit of the science textbooks. The responses were coded and categorized through researchers' cross analysis. The result revealed various problems in using the science textbooks in real classroom context. The problems were divided into three dimensions as inquiry activity aspect, science knowledge aspect, and science learning assessment aspect. Each dimension consisted of several categories. We explained the frequency and representative examples of the problems in each category. These can provide some guidelines and implications for new science textbook developers and science education policy makers.

  • The purpose of this study is to analyze the process of creative science problem solving (CSPS) in elementary school students. To do this, 6 graders (n=9) at a elementary school in Seoul were participated. In this study, fixed eye-tracker with 250 Hz sampling and observation camera were used. The results of this study, the students with higher ability to solve creative science problems had a slower saccade, and had more visual attention on core clues and a greater number of eye changes. Therefore, students with higher ability to solve creative science problems showed more effective eye movement and faster information processing to solve problems. The CSPS types of elementary students were classified as 'declarative knowledge type', 'procedural knowledge type', 'conditional knowledge type', 'knowledge lack type'. Because each type appears to be complementary, CSPS process for elementary students who have integrated the four types was devised. The results of this study can be used as basic data for understanding elementary school students' CSPS and will help to develop and guide creative science teaching and learning programs useful to elementary school students and science gifted students.
