  • To present the suggestions for improvement in science textbooks of high school, scientific inquiry activities in geology of earth science textbooks of Korea and the U.S. were assessed in the areas of the contents, processes and contexts. Regarding the contents of inquiry activities, Korean textbooks contain more number of inquiry activities (5.8 per section) than the U.S. curriculums (4 per section). Inquiry activities of Korean textbooks mostly fall on the interpretation of diagrams and graphs whereas those of the U.S. textbooks more hands-on experiment, data transformation and self designing. As for the number of inquiry process skills per inquiry activity, Korean curriculums contain an average of 1.8 whereas the American ones 3. It suggests that the U.S. textbooks require more integrated process skills than the Korean earth science curriculums. In the process skills of all textbooks studied, the highest frequent elements were inferring and data interpretation; the percentage of these two elements was an average of 73.3% in Korean textbooks and 46.2% in the U.S. This suggests that the Korean textbooks emphasize the process skill on particular area, and uneven distribution of elements of process skills may hinder the development of integration ability of students. particularly in the integrated process skills, the U.S. textbooks presented all 7 elements, while Korean ones presented only 2 to 4 elements, indicating that the Korean textbooks may have weak points in providing various inquiry activities for students compared to the American textbooks. In inquiry context analysis, Korean curriculums provide simplistic inquiry contexts and low applicability to real life whereas the U.S. curriculums provide more integrated inquiry contexts and high applicability to real life.

  • The types of inquiry activities included in Life Science II textbooks under the 2015 revised science curriculum were extracted and compared with those of six major and five different publishing companies. The fact that the number of investigation discussions and presentations (IP) increased and the expressions (EX) were included in each unit was interpreted as sufficient to transform the classroom instruction in the 2015 revised science curriculum into student-centered activities. The type of inquiry activities in student-centered activities such as experiment observation, simulation activities, investigation discussions, and presentations accounted for about 41% more than the 27% of 2009 revised science curriculum. However, since data interpretation type is still the largest, it is necessary to reduce the types of data interpretation and to increase the number of types of simulation activities and expressions in order to expand students' creativity and thinking ability when textbook development is needed in the future. In addition to the development of biotechnology, teachers need to reconstruct diverse science materials for each textbook and then use them for students to induce balanced thinking, and try to expand expressive power, creativity, logic, and critical thinking skills.

  • This study explore characteristics of teaching orientation and pck of science teachers in online-offline mixed learning environment. Data consisted of open-ended survey, semi-structured interview, class observation, field notes from 12 science teachers. We categorized teaching orientation considering both science education goals and science teaching·learning orientation. There were 8 different teaching orientations such as 'understanding science concepts-lecture centered' 'constructing science concepts-inquiry based' 'applying science concepts and inquiry-inquiry based' 'applying science concepts and inquiry-lectured centered' 'analyzing and judging science information-inquiry based' 'developing scientific attitude-inquiry based' 'developing scientific attitude-lecture centered' and 'developing perception of interrelationships among science, technology, and society-inquiry based'. Teachers with inquiry based teaching·learning orientation seemed to have knowledge of science curriculum specific to online learning environment for student inquiry. While teachers with 'understanding science concepts-lecture centered' teaching orientation appeared to have questioning strategy of checking student understanding and strategy of repeating a lecture, teachers with 'constructing science concepts-inquiry based' teaching orientation appeared to have knowledge of instructional strategies to perform online group activities targeting student construction of knowledge and to replace face-to-face group activities with virtual experiments and individual experiments. While teachers with 'understanding science concepts-lecture centered' teaching orientation did not show knowledge of student science learning, teachers with 'constructing science concepts-inquiry based' teaching orientation appeared to have knowledge of student difficulties in inquiry based learning.

  • The purpose of this study was to examine the effects of argument structure on students' writing in implementation of argument-based inquiry using the Science Writing Heuristic (SWH) approach. Participants of this study were 108 8th grade students (three classes). Two classes (68 students) were assigned to an experimental group, and the other class (35 students) was assigned to a comparative group. The experimental group was taught argument-based inquiry using the Science Writing Heuristic (SWH) approach, while the comparative group was taught with the traditional teaching strategy. After implementing this program, the two groups were asked to write summaries using structured argumentation in their writing. The result of this study showed that the experimental group used better argument structure and multimodal representation such as pictures, graphs and examples in evidence than the comparative group. The quality of evidence used in the students' writing was different between two groups. Students of the comparative group only listed fragments of science concepts for evidence to support their claims, but students of the experimental group explained science concepts by giving specific examples. The findings show that argument-based inquiry using the SWH approach was effective on argument structure in students' writing.

  • The purpose of this study was to analyze 'how STEAM activities affect students' science process skills and science-related attitudes'. For more accurate, we have set 31 sixth-grade students from Gyeong-gi Province as an experiment group, and another 31 as a comparative group. We developed a STEAM program based on the educational concepts: Creative Design and Emotional Touch. Through pre-post experiment design, we have introduced TSPS, and Test of Affective Aspects. For TSPS, the comparative group scored higher average grade before the process. After the process, however, the experiment group exceeded the other. The result was considerable enough to verify that the science process skills were bolstered through the STEAM program(p<.05), Similar result was derived regarding the science related attitude. Students in the comparative group originally showed higher degree of interest to science. When the STEAM program was carried out, the standing reversed. The increase in the number of science related attitude indicates the program valid(p<.001). Furthermore, when we asked the students who participated in the experiment how they recognized the STEAM activity, we received positive answers: they consider the program efficient and well suited to the class environment. Conclusively, the STEAM program was proven to be effective for improving science process skills and attitude, and was perceived affirmative.

  • This study explored the effects of pre-service elementary teachers' inquiries into science class dilemmas. By closely examining the characteristics of the pre-service teachers' inquiry processes and changes in their educational decisions, the effectiveness of using dilemmas as part of teacher education was determined. Twenty fourth-year university pre-service teachers participated and conducted inquiries into science class dilemmas over seven weeks. Based on pre- and post-questionnaires, KWHL tables, inquiry reports, discussions, and group class presentations, the major factors that influence the pre-service teacher's decision-making changes were extracted. The pre-service teachers found the science inquiry process meaningful when exploring the science topics covered in the dilemmas, and claimed that elementary school students would be able to engage in meaningful science explorations if they learned science through inquiry. Furthermore, the pre-service teachers explored the thinking processes and background knowledge of the students in different ways. Documents such as teacher's guides and the curriculum were examined and the students' thought processes were identified through interviews with the teachers and students, which were found to reflect their educational decision-making. Moreover, it was recognized by the pre-service teachers that depending on the situation, alternative teaching methods were possible. The focus on the unstructured dilemma problems provided the pre-service teachers with problem-solving situations that triggered scientific inquiry and exploration of student thinking and revealed the complexity of science teaching and learning. Based on these results, the teacher education implications for using dilemma cases are discussed.
