The purpose of this study is to analyze inquiry tasks of textbooks in middle schools social studies under the information literacy process and find out teacher librarians' educational information service on the side of information literacy education. Results of the analysis show that middle school students who carry out the inquiry tasks of social studies should select sources, seek its' related information and create their products through writing reports or presentation. Compared with information literacy process of the "Library and Information Skills", the First step of task definition and figuring out information needs and the Third step of representation of information are being implemented. For this reason, teacher librarian could reduce social studies teachers' burden of class and promote students' inquiry activities by teaching skills of suitable materials seeking strategies for solving their task, understanding and synthesizing the information and evaluating their process and result. Therefore, it is necessary to activate collaborative teaching between the teacher librarian and the social studies teacher based on the information literacy.

The purpose of this study is to investigate the effects of learning using computer-based science inquiry program. To this end, the three lessons computer-based science inquiry were developed in domain of material's properties. The developed program was put into K middle school located in Seoul and the effects were verified. For the experimental group, the three lessons computer-based science inquiry related to the separation of mixture were introduced, and for the comparison group, the contents presented in the textbook were introduced as a teacher-centered teaching method. To verify the effects of the program, 2-way ANCOVA was performed on positive experiences about science and science core competency, and 2-way ANOVA was performed on academic achievement. As a result of the study, there were significant differences between the two groups in positive experiernces about science and scientific core competencies and academic achievement (p<.05), and group^*gender interaction effect was only significant in academic achievement (p<.05). From the results of this study, we could see the possibility of using a computer-based science inquiry program as a chemistry teaching method that enables sustainable scientific inquiry.

The purpose of this study is to analyze the experiences of teachers who participated in the development of online science class videos in the context of covid-19, their perception of online science class, and the characteristics of the online science class content developed by teachers. A survey and interviews were conducted with ten elementary school teachers who made online science class videos themselves. Also the characteristics of the online science class were investigated by analyzing the online science class video produced by the participants. As a result, participants in the study recognized the lack of production time, difficulty in filming and editing, concerns over misconceptions, the problem of solving copyrights for existing materials, and the burden of external disclosure. Although it was a teacher who had experience producing online science class video contents, no research participants actively answered the merits of online science class. On the other hand, the study participants cited that the shortcomings of online science classes were that students had fewer opportunities for inquiry and lack of communication or interaction. In particular, these shortcomings were thought to have a great influence on the quality of online science classes, especially in making inquiry classes difficult. Some teachers took a negative view that online science classes could not completely replace face-to-face classes. However, if multiple teachers are presented with supplementary teaching activities that complement the content-based online teaching method, the method of combining online science classes and face-to-face classes is not. Through the analysis of the contents of the online science class, the introduction and arrangement steps of the online science class were similar to the process of the face-to-face science class, but the inquiry step and the conceptual explanation step showed a big difference from the face-to-face science class.

Recently, there has been a dramatic increase in the number of cases that have formed and operated teachers' learning communities through cross-curricular consulting at the school level. The purpose of this study is to explore cross-curricular instructional consulting as an activity of teachers' learning communities at the school level, and investigate the effect of cross-curricular instructional consulting on middle school science teaching. We analyzed features and limitations of cross-curricular instructional consulting revealed in three case studies in middle school, including open classes and instructional consulting sessions, and conducted additional instructional consulting on the same videotaped science classes with science experts from outside. According to the results, science inquiry experiments are often replaced with text reading and interpreting, students' misconceptions and exact scientific representations are ignored, and the goal setting as well as class coverage has been questionable and disputable in science classes resulted from cross-curricular instructional consulting. Discussed in the conclusion are the necessity of cross-curricular instructional consulting in middle school, and ways to overcome limitations of the method of cross-curricular instructional consulting, including alternatives to a praise-only policy in cross-curricular instructional consulting, ways to use cross-curricular instructional consulting without compromising the subject's essence, and ways to improve the undue authority of consultants.

The purpose of this study is to investigate the effects of lessons adopting portfolio assessment regarding feedback on elementary school student's scientific knowledges, inquiry abilities and their perceptions of it. For this study, two classes of 5th grade elementary school in suburb were selected. As an experimental group, one class was selected to apply the lessons adopting portfolio assessment regarding feedback, and the other class as a control group was selected to apply the lessons adopting portfolio assessment without feedback. The investigator taught and assessed both group students. The results showed a significant difference in scientific knowledge between the experimental group and the control group (p<.05). More detailed analysis of scientific knowledge found that the feedback effect was statistically positive in the memory and the understanding domain, but there was no effect in the application domain. No statistical difference was identified in inquiry abilities. The results of the questionnaire on the perceptions of portfolio assessment showed that students of the experimental group had higher positive responses on the 'perception about the effects of lesson' and on the 'perception in scientific attitudes' than the control group. However, the control group students had higher positive responses on the 'perception about self-evaluate of their own portfolio' and the 'perception about need of feedback' than the experimental group.

This study is on the teaching method for the students who belong to the same school (one, the gifted class, passed gifted education of Science High school ), 1-1, face-to-face learning (two, good students in regular classroom) with a teacher, paired learning teams (4 people, gifted classes), and group lessons (20 people, gifted classes) and using the justification analysis framework tool(PIRSO) of Kim(2010) analyzes the justification element of the students in the group classes regular polygons paper was to explore ways to improve the justification of the folding maps activities. As a result, the width of the largest polygon difficulty level appropriate to the class for gifted elementary school classes but the individual learning style of the 1-1 face-to-face with a teacher or discussion with colleagues and cooperative approach is justified, rather than the material of the study of origami activities it turned out to be more effective in improving the level of justification. Unlike the individual learning activities, the exploration for class is the need to strain in parallel to the student is selected as needed, rather than serial manner was confirmed that it is necessary to clearly present problems even from the beginning. Development of teaching through the implications obtained from this method of reconstruction activities and proposed improvement measures for questioning.

Understanding about the Nature of Science (NOS) is element of scientific literacy. Its importance is emphasized, especially understanding about NOS was presented as goal of science education on the fifth curriculum in Korea. Attempt of teaching NOS has been continuous in school, that was limited by method of using History of Science. Except method of using History of Science, Experimenting is appropriate for method of teaching NOS. We expected that is effective to apply reflective approach method for understanding the NOS and composite lesson to emphasize reflection and discussion to general experiment class in the school. We applied experiment class to emphasize reflection and discussion to second grade students in the middle school and researched whether positive reflection and discussion is helpful understanding the NOS in science experiment class or not, through questionnaire about NOS and analysis of observation and interview. As a result, experiment class to emphasize reflection and discussion was effective for scientific inquiry skills and sociality of scientific inquiry, particularly for relation observation with deduction and possibility of variable analysis to experiment result. Therefore, experiment class to emphasize reflection and discussion is effective for understanding the NOS.

The effects of learning using Information Communication Technology(ICT) on the students' scientific inquiry ability and science-related affective characteristics were analyzed in Earth History and Crust Movement units of science textbook for eighth graders. For this study, two classes of middle school second students in Chung-nam were selected and taught for six week under different teaching methods. One class is the test class taught with ICT applied teaching materials and the other class is the control class instructed by a conventional method. One week before the experiment, both classes were given tests on scientific inquiry ability and science-related affective characteristics, and they were tested again after the experiment. The results of scientific inquiry test showed statistically meaningful differences in the experimental class and the control class. The experimental class showed statistically meaningful difference in scientific inquiry test. Science-related affective characteristics test showed no statistically meaningful difference in the experimental class. Among three scientific science-related affective characteristics, especially the one fields of interests showed statistically meaningful differences which suggest that learning using ICT has a positive effect on the expanding of students' science-related affective characteristics.
