  • The purpose of this study is to develope the more effective chemistry teaching strategy through analyzing the demanded cognitive levels of contents in high school chemistry I textbooks and the cognitive levels of students who learn these textbooks. For this purpose, the levets of cognitive development stages of 821 second grade students of high schools in Seoul City were anaIyzed using the GALT short version test. The demanded cognitive levels of understanding the contents of chemistry I textbooks in high school were analyzed using the curriculum analysis taxonomy developed by CSMS (Concept in Secondaly Mathematics and Science) program of the Great Britain. The resuIts showed that the proportion of students in the concrete operational stage, the transition stage, and the formal operational stage was l0.7%, 43.0% and 46.3%, respectively. The demanded levels of textbook contents were mostly the early formal operational stages. The concepts demanded the level of the late formal operational stage were 'atomic and molecular weight', 'stoichiometry of chemical reaction', and 'periodic properties of elements'. The results will be helpful for teachers in knowing what concepts are difficult for students to understand and in planning strategies for teaching those concepts. To demonstrate the application of the results obtained in this study, an example of developing teaching strategy which includes the adjustment of cognitive level of contents was shown.

  • In this study, we analyzed he computer operating system curriculum in primary and middle schools and suggested the content framework for them through review of previous research. After surveying primary and middle school teachers, we developed the framework based on the spiral curriculum. Through these surveys, we were able to determine when and how students should be introduced to the as curriculum. The content framework focuses on two areas: understanding and practicing computer OS. Each area has 4 levels which are based on the students' grade. We suggested developing textbooks and materials about computer OS; establishing Information Science as a part of the primary school curriculum: and offering lectures about computer OS to student teachers at the National Universities of Education.

  • As the 2015 revised curriculum is being implemented from 2018, efforts are being made to cultivate scientific literacy among students in the field of science. Scientific experiments help students to develop their interest in Science and their scientific attitudes. Learning through experimentation rather than learning scientific facts increases learners' understanding, and can be remembered longer. Therefore, experiments in Science subject are very important. However, in middle schools, scientific experiments are not performed due to the lack of time, budget and experimental material. In this research, we analyze middle school science textbooks, conduct questionnaires for students of science pre-service teachers, select the most important science experiments, and develop a mobile App to simulate and experience scientific experiments with the App. The proposed App is developed in a game format using quest-based learning methods to gain learning enhancement. It is also made using Unity. In this paper, after developing the app, we propose the direction of STEAM contents development through analyzing the difference from existing apps and the feedback from users.

  • In this research, we analysed definitions and examples of conductor and electrolysis concept in middle school science textbooks. We also surveyed 9 senior pre-service teachers' understanding of the concept definitions and appropriate examples. From the analysis of the textbooks, we found that the possibility of misunderstanding of learners is high because of the broad definition concept and narrow list of examples. After confirming the differences among pre-service teachers' understanding of the subject through questionnaires and interviews, they also debated for a need to an agreement on scientific concepts. The pre-service teachers recognized the meaning of social constructivism and the need for an agreement process in teaching science concepts.

  • A questionnaire was administered, and all responses were analyzed to examine prospective teachers' conceptual understanding of the relationship between dew point temperature and absolute humidity in air parcels. The responses revealed that many prospective teachers have substantial misconceptions about the relationship. For example, some thought that the absolute humidity and the dew point temperature are proportional to each other, and that the dew point temperature is proportional to the water vapor mass in the parcel. The misconceptions seemingly stemmed from inadequate descriptions on the relationship in middle-school science textbooks of the 7th and 2007 revised curricula. The study notes that the first year students' textbook of the 2015 revised curriculum introduced the concepts of evaporation, condensation, and volume changes as a function of gaseous pressure and temperature, from a perspective of molecular motion. It is suggested that keeping this perspective in the middle school curriculum, while introducing water vapor pressure as the measure of water vapor amount and dew point temperature, should help prevent middle school teachers and students from having misconceptions. There should be a concerted effort to make the science curriculum more consistent and coherent across the grade levels.

  • The purpose of this study is to examine the text and learning activities of Korean and American home economics textbooks from the perspective of building adolescent empowerment and to suggest an alternative framework for the textbook. An in-depth content analysis was conducted for the Korean and American home economics textbooks. We analyzed the text and learning activities in the textbook on three levels of empowerment: Micro, Meso, and Macro. Major findings are as follows. First, in the case of Korean textbooks, the results showed that the three levels of empowerment were off-balance (Individual Empowerment: 55%, Group E: 37%, Organizational E: 8%). The educational contents in Korean textbooks were described at the Meso-level. In the case of the American textbooks, the result showed that the educational contents of IE(43%), GE(40%), and OE(17%) were relatively balanced. Therefore, the educational contents of the American textbooks were described at the Macro-level. Second, the learning activities in the Korean textbooks put a greater weight on IE at 66%, followed by GE at 25%, but OE at 9% only. The results showed that learning activities in Korean textbooks were presented at the Meso-level, but that the three levels of empowerment were significantly off-balance. In the case of the American textbooks, the results showed that the learning activities were comparatively well balanced at IE(36%), GE(40%) and OE(23%). Therefore, learning activities in the American textbooks were presented at the Macro-level. Based on the results, we suggested an alternative framework for 'understanding of self as an adolescent' unit, to build adolescent empowerment at the Macro-level.

  • Eisner emphasized the importance of problem-solving objectives and expressive objectives in addition to behavioral objectives, and communication through multiple modalities including linguistic, visual, aural, spatial, gestural modes. This study analyzes 'Libraries and Information Life,' a textbook developed for information literacy instruction, by dividing it into educational objectives types(behavioral, problem-solving, expressive) and multimodal modes(linguistic, visual, auditory, spatial, and gestural), and seeks to derive implications for setting educational objectives for information literacy instruction and developing textbooks. The textbook has four volumes for elementary low-grade, elementary high-grade, middle school, and high school levels. Educational objectives were extracted from the textbooks, and 3 librarian-teachers were engaged in the analysis of these objectives. The main findings and implications of this study are as follows. First, when looking at the types of educational objectives, the proportion of behavioral objectives was found to be excessively high, and there is a need to strengthen the proportion of problem-solving objectives and expressive objectives. Second, problem-solving objectives tend to overlap with behavioral objectives, indicating a need to develop problem-solving objectives with defined conditions and solution requirements. Third, expressive objectives concentrated in specific units need to be placed evenly in other units. Fourth, in the case of multi-modality mode, the proportion of the linguistic mode must be reduced, the proportion of the visual, auditory, spatial, and gestural modes must be increased, and it is necessary to set educational objectives with clear characteristics of each mode.

  • This study examines how prospective earth science teachers perceive the concept of "equilibrium" and "interaction between Earth's spheres" in understanding Earth's radiative equilibrium and tries to identify their misconceptions. For this purpose, a questionnaire was designed and put to them to look into their thought flow based on the items that appeared in the national level evaluation. As a result of analyzing their answers, even though all the prospective teachers correctly described the concept of radiative equilibrium, about 90% of them did not apply the concept of radiative equilibrium to the new environment of the Earth without atmosphere. They do not seem to be able to smoothly derive the concept of a new 'interaction' between the changed regions and a new 'equilibrium' that will be reached over a long period of time. In this respect, it is likely that the textbooks had some influence on the formation of their concepts. In particular, high school Earth Science textbooks describe the Earth's radiation equilibrium in a quantitative manner, focusing on the heat budget of the equilibrium state rather than the process of reaching radiation equilibrium. Such an approach of textbooks might be an obstacle to fostering students into creative convergence-type talents pursued in the 2015 revised curriculum. Meanwhile, in order to eliminate the misconceptions of students often found in the understanding of Earth's radiation equilibrium, this study suggests that the core concepts need to be dealt with more attention even in college courses for training prospective teachers.

  • Purpose: The purpose of this study was to analyze and assess the current situation of Korea's school health education program and to establish measures to efficiently carry out school health education in Korea. Method: The survey was conducted through the internet with the health educators of elementary, middle, and high schools nationwide to assess the current condition of school health education programs, and 2,459 samples were collected which accounted for 23.4% of the total respondents. Results: According to school health educators on the enforcement of health education, the higher the education became, the less the health education was enforced. The enforcement rate was 96.9% in elementary schools, 76.7% in middle schools, and 67.3% in high schools. The major reasons were found as difficulty in securing class time (54.5%) and other excessive workloads (20.9%). As a result of the health education awareness survey, over 99% answered that health education is needed, over 80% answered that the education requires independent health textbooks, and over 95% answered that health educators are suitable for the person in charge of the education. Conclusion: This study will be a useful in establishing a detailed policy on enhancing school health education in the future.

  • The purpose of this study was to analyze the relevance of the school science contents that have been implemented for the 7-10th grade students in Korea since 2001. To fulfill the purpose of the study, we 1) analyzed the 7th national science curriculum of Korea, California science standards, the national science curriculum of England, Japanese national science curriculum, and current Korean and Japanese science textbooks, 2) conducted a nationwide survey in order to gather opinions from students, teachers, and science specialists. The main findings of this research were as follows: First, the number of topics presented at each grade level should be reduced and similar topics and themes should be integrated for students' deeper understanding. Second, science contents were excessive compared to the allotted teaching time and to foreign countries. Thus, the excessive overlapping and repetition of science contents should be avoided among the primary, middle and high school level, and the number of science concepts and activities should be reduced to an appropriate level considering time allotment for science classes, teachers' workload, laboratory conditions, etc. Third, to cope with the decreasing students' understanding and interests in science as school level and school year goes up, the science curriculum and textbooks should be developed to allow for student to learn science concepts by solving problems confronted in their daily lives. Fourth, a differentiated curriculum such as in-depth and supplementary course should be described not in science contents, but in teaching and learning strategy.
