The purpose of this study was to test the effects of practical reasoning home economics instruction on middle school students' views of home economics. Thomas(1986) categorized six alternative views of home economics as education for women, manual training, application of science, household management, family development, and an intervention. This study carried a quasi-experiment research with an independent variable of types of instruction and a dependent variable of views of home economics. The experiment was carried with the sample of 137 8th grade students in Gwangju area for ten class hours. Paired t-test was performed to examine the pretest-posttest differences of each experiment group and comparison group. The results showed that practical reasoning instruction improved level of the view of home economics as an intervention, and decreased level of the view of home economics as manual training. From the results of this study, conclusion can be made that practical reasoning home economics instruction is effective in changing to the appropriate views of home economics. Also it is expected that current Korean home economics textbook can lead to the views of home economics as household management and as family development.

This study analyzed the uses of visual representations of particles in the matter units of the middle school science textbooks developed under the 2015 Revised National Curriculum. The material units in four textbooks were divided into explanation, inquiry, and evaluation sections, and visual representations of particles presented in the science textbooks were analyzed by the use type, the activity type, and the level of activity. In the explanation section, the visual representations of particles were mainly presented in the auxiliary use type, and in the inquiry and evaluation section, they were mainly presented in a direct use type. In terms of the activity types of the direct use of visual representations of particles, the interpreting activity was mainly presented in the explanation and evaluation sections, while the generating activity and completing activity were presented in relatively higher proportion in the inquiry section than the other two sections. In terms of activity level, identifying was the most common activity level in the explanation section, and inferring was the most common activity level in the inquiry and evaluation sections. Based on these results, the implications for the presentation and uses of visual representations of particles in science textbooks are discussed.

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 attempts to analyze the causes of low affective achievement of elementary, middle, and high school students in Korea in science. To this end, a total of 27 students, three to four students per grade, were interviewed by grade from the fourth grade of elementary school to the first grade of high school, and a total of nine teachers were interviewed by school level. In the interview, related questions were asked in five sub-areas of the 'Indicators of Positive Experiences about Science': 'Science Academic Emotion', 'Science-Related Self-Concept', 'Science Learning Motivation', 'Science-Related Career Aspiration', and 'Science-Related Attitude'. Interview contents were recorded, transcribed, and categorized. As a result of examining the causes of low science academic emotion, it was found that students experienced negative emotions when experiments are not carried out properly, scientific theories and terms are difficult, and recording the inquiry results is burdensome. In addition, students responded that science-related self-concept changed negatively due to poor science grades, difficult scientific terms, and a large amount of learning. The reasons for the decline in science learning motivation were the lack of awareness of relationship between science class content and daily life, difficulty in science class content, poor science grades, and lack of relevance to one's interest or career path. The main reason for the decline in science-related career aspirations was that they feel their career path was not related to science, and due to poor science performance. Science-related attitudes changed negatively due to difficulties in science classes or negative feelings about science classes, and high school students recognized the ambivalence of science on society. Based on the results of the interview, support for experiments and basic science education, improvement of elementary school supplementary textbook 'experiment & observation', development of teaching and learning materials, and provision of science-related career information were proposed.

The objectives of the study were to. 1) explain the seriousness of environmental problems and the importance of environmental education in rural development , and 2) explore more effective and efficient ways of environmental education for agriculture and rural development in Korea. The world has rapidly changed and concepts such as clientele -centered, efficiency, and globalization are flowing under this change. Agriculture or rural development is not an exception. In order for agriculture as an occupation and rural communities to have competitiveness in efficiency and attractiveness, it is important to develop and execute a well-planned program for agriculture and rural development. Otherwise, farmers and rural inhabitants will continue to leave the agriculture and rural areas. Frequent recent reports of newspapers on nit and water pollution, including nutrients and pesticides have brought attention to the seriousness of environmental problems in Korea. Environmental concerns should consider in planning and executing the rural development program. People want to get contamination-free foods, water and fresh air. They can and are willing to pay their money for high quality food, water and a better living environment, as their incomes have been increasing, Agriculture and rural communities may have competitiveness in these aspects. It is irony that environmental concerns makes the possibility of changes in agriculture and rural development in Korea. Environmental education will have an increasingly important role in agriculture and rural development. Environmental problems relate to the human behavior in various aspects. Many environmental problems are mainly rooted to people's ignorance and spending-habits, and lack of technology related to environment. These human behaviors are the focus that environmental education should teach and change. Environmental education has been carried out through various subjects in school education in Korea, but "Environment" in middle school and "Environmental Science" in high school were separated as a regular subject from 1996. Environmental education still has a lot of room for development from a theoretical frame work. Environmental education should be carried out as action-oriented, student-centered programs. Various teaching materials, programs and proper supporting budget should be developed so that environmental education fulfills its necessary role well in agriculture and rural development. A textbook about the environment alone will not guarantee a high quality environmental education.

In order to investigate the differentiation for gifted students, we studied the present condition of differentiation applied in science classes at regular schools, private educational institutes, and gifted education centers. A questionnaire regarding differential instruction was administered to 90 eighth graders enrolled in university- based gifted centers in Seoul. The results of chi-square testing based on the questions and educational institutions showed that students used only a textbook at regular schools and several workbooks at private educational institutes, while students could use various specialty publications at gifted education centers. Students frequently took post-test at regular schools and private education institutes. Further, at regular schools and private education institutes, students who completed curricular activities early spent their time performing unrelated tasks or reviewing the lessons or solving problems. Gifted students tend to develop their interests by themselves through science classes at regular schools. However, efforts to group students according to their interests were predominant at the gifted education centers. The response rate for students' choice of curricular activities and teachers' preparation for advanced learners were the lowest in all questions.

In this study, the illustrations in the 27 middle school science textbooks developed under the 2009 Revised National Curriculum were analyzed in the aspect of gender-role stereotype, and the results were compared with those of the 2007 Revised National Curriculum. The results of the analyses revealed that male pupils in the illustrations appeared more frequently than female pupils at all grades, and that the gender gap of pupils appeared in the illustrations slightly increased in comparison with those of the precedent curriculum. Similar to those of the precedent curriculum, the gender gap in other activities were particularly large regardless of publishers. In the illustrations of adults, the frequencies of male outnumbered female, and highly gender biased compared with those of pupils to mean that gender bias in the illustrations of adults were not improved at all. While the ratio of female was high in house works, that of male was high in outdoor activities regardless of publishers. The gender gap in outdoor activities increased in comparison with that of the precedent curriculum. Most occupations illustrated were male-dominated, and the majority of scientists were portrayed as male.

The purpose of this study was to analyze the dietary life units of Korean and American high school home economics textbook according to Habermas's three systems of action and to find out how the three systems of action are reflected in the learning objectives and activity tasks of the textbook. To achieve this purpose, this study analyzed the learning objectives and activity tasks of the dietary life units in the textbooks of 'technology & home economics' and 'home economics science' in Korea, and 'succeeding in life and career' in America using a content analysis technique based on Habermas's three systems of action. In analyzing the content, each learning objective or activity was matched with one of the three systems of action by examining the context. In some cases, two or more systems of actions were integrated in one activity. This is a case where a series of learning tasks that involve different action system were grouped into one. The numbers of learning objectives and activities of the units of 'technology & home economics', 'home economics science' textbooks of Korean high schools and 'succeeding in life and career' dietary life of American high schools were 3, 26, and 248, respectively. In Korean textbooks, the percentage of communicative action was highest among the three systems, that is, 66.7% for 'technology & home economics' textbooks and 50% for 'home economics science' textbooks. In comparison technical action was the highest in American textbooks at 66.5%. Activities related to technical action included cooking, conducting research on health and food, or conducting experiments. The activities related to communicative action included role play related to health and table manners, or writing reports after conducting surveys or interviewing professionals. The activities related to emancipative action were to social participation activities such as service project in relation to health and food, or to find problems that occur in dietary life and think about be best solution through practical reasoning.

This study was to investigate the effective order of instruction for students learning the concepts of chemical change. Chemical change was considered as the important area in 8th grade chemistry part. The study consisted of 168 8th grade students, two classes of boys and girls each, from a middle school in Seoul. They were divided into two groups, the experimental group and the control group. The control group was taught in the order, which was presented in the science textbook; chemical change, atom, and molecule (CAM). For the experimental group, the order was molecule, atom, and chemical change (MAC). From the results of the study, there was a statistically significant difference between the control group and the experimental group. But the interviews indicated that the students were confused with the MAC method in spite of the effective learning. Therefore, for more effective concepts learning without a confusion, we need to provide our students with various learning sequences of science textbooks rather than fixed learning sequences.
