This study aims to analyze the direction of the reading education programs based on the 2015 revised curriculum and to seek the plans for the school library and the teacher librarian to be able to contribute them. For this purpose, the types of school-based reading education programs in the report of 100 excellent school curriculum in 2016, which was first applied by the amended curriculum were analyzed through multiple intelligences. Upon the analysis results, the reading education programs in the schools showed to be operated with interpersonal Intelligence. Community-aligned reading was the most frequently operated in the primary schools while student reading club activities were the most common in the middle and high schools. In case of reading education program related to linguistic intelligence, the most commonly operated ways were reading books, writing with literatures, and writing book report, in primary, middle, and high schools, respectively. In case of reading education program related to spatial intelligence, media production type showed the most commonly operated in all types of schools. However, there was no reading program related to naturalist intelligence. Based on these analysis results, the plans to contribute the activation of reading education programs by school libraries under the 2015 amended curriculum were suggested in the aspects of development of connection programs with teachers, students and parents as the center of education community, installation and operation of maker spaces and enhancement of program management and inquiry-based learning competency of teacher librarians.

In this study, the texts of science textbooks of the past 20 years were collected in order to systematically carry out researches on scientific languages and scientific terms that have not been noticed in science education. We have collected all the science textbooks from elementary school to high school in the 6th curriculum, the 7th curriculum, and the 2009 revised curriculum, and constructed a corpus comprising of 132 textbooks in total. Sequentially, a raw corpus, a morphological annotated corpus, and a semantic annotated corpus of science terms, were constructed. The final constructed science textbook corpus was named K-STeC (Korean Science Textbook Corpus). K-STeC is a semantic annotated corpus with semantic classification and classification of scientific terms, together with meta information of bibliographic information such as curriculum, subject, grade, and publisher, location information such as chapter, section, lesson, page, and sentence, and structure information such as main, inquiry activities, reference materials, and titles. Throughout the three-year study period, a new research method was created by integrating the know-how of the three fields of linguistic informatics, computer science and science education, and a large number of experts were put in to produce labor-intensive results. This paper introduces new research methodologies and outcomes by looking at the whole research process and methods, and discusses the possibility of future development of scientific language research and how to use the results.

One of the important competencies in knowledge and information society is the competency of Knowledge information processing. This is closely related to science education and described as one of the core competencies in the 2015 national curriculum revision. Even with a general agreement of the educational necessity of this competency, its practice in class depends mostly on teachers' will. Therefore, we surveyed science teachers' perceptions and classroom condition about the competency of Knowledge information processing, and we analyzed the questionnaires of 64 middle and high school teachers in Seoul and interviewed three teachers. As a result, all teachers shared the importance of Knowledge information processing competency and explained it in terms of social paradigm and goal of the subject. However, there were not many cases of actual practice in class. The teachers answered that time for Knowledge information processing competency is not enough in class and they also lack of PCK on this competency. About half of the teachers had experiences in teacher training about Knowledge information processing competency but most of their experiences are related to information utilization literacy. The importance of Knowledge information processing competency was very high in three factors (collection, analyzation, and utilization), among which information analysis was the highest. Middle school teachers showed higher scores in most questions even though the differences were not significant, and high school teachers showed higher scores in the importance of information sources at a significant level. In order to cultivate competencies, it is necessary to expand the meaning of science inquiry so as to cover this competency and to consider ways of linking with other subjects and develop methods of teaching and learning.

The purpose of this study was to examine the effects of the application time of differentiated instruction in terms of learners' science academic knowledge achievement and their attitudes toward science. The findings of the study were as follows: First, the experimental group was significantly higher than the control group (p<.05). Second, the academic knowledge achievement of high ability students of two subgroups was not different (p>.05), but the achievement of low ability students was higher in experimental group than in control group (p<.05). Third, the experimental group showed higher improvement in attitude toward science than the control group in three areas of the Test of Science Related Attitudes (TOSRA) (p<.05): 'Adaptation of Scientific Attitudes', 'Enjoyment of Science Lessons', and 'Career Interest in Science'. However, there was no significant difference between the experimental and control groups in the area of 'Attitude to Scientific Inquiry' and 'Leisure Interest in Science'.

The purpose of this study is to explore the effects of self-directed field learning practices on student’s academic achievement and self-directed learning characteristics regarding the level of learning ability. To conduct this study, 196 students of high school students in Busan were chosen and parted into either the experimental group (98 students) or control group (98 students). Each group is classified into three categories: high level (24 students), middle level (50 students), and low level (24 students) according to the level of learning ability by the academic achievement pre-test. The areas chosen for experimenting this study range from Dusong peninsula, Molundae in Saha-gu, Songdo in Seo-gu, Pusan. Then the inquiry-model of self-directed field learning which focuses on learner-centered activity was designed based on theories concerning field learning and self-directed learning, and was applied to the experimental group. In conclusion, this teaching method using self-directed field learning is expected to improve academic achievement in science subject and increase students’ self-directed learning characteristics regardless of the students' level of academic achievement.

Recently it has been claimed that character education should be applied not only in ethics but also in other disciplines including science education. With several attempts at character education in previous research on science education, the examination of its requisite and components is needed. This research investigates the necessity and elements of character education to be improved upon in science classes through questionnaires and focus interviews of experts in the field of science education such as secondary school teachers, professors, and researchers. They recognize that character education should be adopted in science education with three backgrounds: scientist activities, the field of secondary school, and inquiry education. Based on moral education and citizenship, elements of character education in science class are comprised of four essential character elements including honesty, sympathy, tolerance, and self-esteem, and seven practical character elements that are divided into personal qualities: sincerity, responsibility, and self-control and social qualities: consideration, openness, communication, and cooperation. Their validity and importance are accepted by experts.

The purpose of the study was to produce resources to help develop instructional methods and programs for school science to reduce gender differences in science achievement by analyzing TIMSS-R results according to item type, benchmark, and content category. Korean male students performed higher than Korean female students and gender differences of Korean students were higher than international means in all item types including multiple-choice, short answer, and extended response type. GDI(Gender Difference Index) of Korean students was lower than international mean in top 10% benchmark but higher than international means in other benchmarks. Korean male students also exhibited higher performance than Korean female students in all content categories except scientific inquiry and the nature of science category. Regarding items that GDIs were higher than 10, the number of items belonged to life science and earth science category was relatively larger and a high percentage of them was not included in school science curriculum. In addition, the items were equally distributed in each performance category. In sum, the study showed various gender differences according to item type, benchmark, and content category. The results could be used to find appropriate instructional methods to reduce gender differences in science achievement.

The purpose of this study was to investigate the perceptions and practices of secondary science teachers who participated in an Earth science teachers' research roup about teaching geologic field trips. Four Earth science teachers participated in this study. Data included field trip observations, semi-structured interviews with teachers and students, and analysis of instructional materials and students' reports from the field trip. Field trip observations and interviews were video- and audio-taped and transcribed. Results indicated that teacher participants focused more on aesthetic objectives for geologic field trip. The participants' instruction tended to show rather teacher-centered explanation due to limited time at each field site though various teaching strategies were used at times to engage students in a scientific inquiry. This group of teachers strived to develop their professional ability to guide geologic field trip by working with a small study group with colleagues, participating geologic field trips, and enrolling graduate programs.

The objective of this study is to examine the cognitive process that undergoes a middle student’s conceptual change about the universe by the cognitive conflict, using science history materials as a teaching strategy. Four eighth graders were selected and classified by three cognitive level. Students were interviewed and conducted to an inquiry activities regarding their viewpoint about the universe after each class, and their conceptual change patterns were analysed from pre-test and post-test. This study showed that each student held dissimilar astronomical preconceptions and various misconceptions about celestial motion. Students at the formal operational stage and transitional stage experienced the conceptual change from geocentricism to heliocentricism by instructional model upon the science history materials. Student at the concrete operational stage had either unscientific conception, no conception, or could not have a conceptual change even when being presented with an environment that arouses cognitive conflict ($R^2$: Phase change of Venus and its Rise and set time). They ended up having a cognitive change from geocentricism to heliocentricism by solving another problem ($R^2$: Relation between visible diameter and position of Mars). After the instruction, a conceptual achievement progress was reported with a $10\%$ improvement. Therefore, the instruction model based upon science history was effective on student’s scientific conceptual change.

The TIMSS assessment is conducted every four years, and Korean fourth grade cohort in TIMSS 2011 participated in TIMSS 2015 again as eighth graders, which produced the first achievement data of the cohort group of elementary and middle schools. In this study, in order to investigate the causes of the decline in Korean students' science achievement with grade changes from the fourth to the eighth grade, we analyzed educational context variables such as characteristics of students, teachers, and classroom instructions of the top 5 achievement countries participated in both TIMSS 2011 and TIMSS 2015. According to the results, students' sense of school belonging increased, whereas students' positive attitudes toward science teaching decreased with the grade change from the fourth to the eighth. As for the teacher characteristics, the teacher's professional development activity increased, and the teacher's confidence in science teaching showed similar tendency to the international average. Regarding classroom instruction characteristics, the frequency of inquiry-related science activities was highest at the fourth grade, and lower than the international average at the eighth grade. Based the results, we suggested implications for science teaching and learning as well as further studies including development of differentiated strategy by the school level to improve students' achievement, the necessity of converting into more student-engaging science classes, and the necessity of in-depth study on the teacher related educational contextual variables.
