This study investigated the impact of grouping methods on free inquiry implementation through the use of mixed research methods. Some 113 7th graders and 2 science teachers in two middle schools participated in this study. The 113 students who participated in this study were grouped by homogeneity and heterogeneity according to scientific inquiry skills and personality types respectively, and performed free inquiry activities on the same subject for three weeks. Data were collected by means of a test on science inquiry skills and from focus group interviews with 36 students and in-depth interviews with 2 teachers. The quantitative results of this study showed that homogeneous grouping was more effective than heterogeneous grouping in improvement of scientific inquiry skills. Meanwhile, the qualitative results revealed both the students and teachers perceived that it was effective to compose a small group according to their affective quality than their cognitive quality. Particularly, most of the students preferred the method of small group from the personality types. Some students and both teachers proposed that it is necessary to collect enough information on students and to use them in mixture with the method of small group according to the affective quality.

The purpose of this study is to provide the basic data for morality of education in home economics education. Through research on the state of morality of education, the following criteria can be achieved ; recognition of the importance, and the level of teaching performance regarding the contents of morality education in home economics instruction. The basic data were obtained by looking at the differences between the recognized importance and the level of teaching performance. Data were collected from the survey mailed to the teachers responsible for home economics area in $\lceil$Technology${\cdot}$Home Economics$\rfloor$ in middle schools in Korea. The 335 questionnaires collected were used for final analysis. SPSS/WIN 10.0program was used for calculating and analysis the frequency, percentage, average. standard deviation. Firstly, most of the home economics teachers show that they continually try to implement morality education through each home economics lesson plan. They focus their attention on the main theme of the lesson of a particular nit, that deals with family life. For example, an excerpt from a particular unit may be the 'Understanding of myself and family members'. Most home economics teachers believe that a family setting and/or schools, whether private or public institutions, are appropriate places for productive education. As well, each of these educational settings, should take complete responsibility for teaching morality of education. As a way to activate the morality education, teachers believe that working with the students and understanding the needs of their students, along with the cooperation of parents, are key factors in the teaming process. Another way is the change of teacher's perceptions and educational conditions or environment. Secondly. home economics teachers in middle school. are showing a higher level of understanding on the importance regarding the contents of morality education, which can be noticed through the high level of their teaching performances. Regarding the importance of morality education, the first priority goes to showing respect for parents and the elderly, as well as sexual ethics and respect for life must always be taken into consideration. In regards to the level of teaching performance, the first priority goes to responsibility and co-operation. Secondly. showing respect for parents and the elderly and sexual ethics will be the third. Through data achieved through this study, the majority of home economics education teachers believe that morality education in home economics education is very important and a key factor in their teaching practices.

This study aimed to examine the operation of the Home Economics education courses in the graduate schools of education, and to find out how graduate students perceive them. Data were collected with the use of handbooks issued by 11 graduate schools of education located in Seoul, and through telephone conversations with the administrative staff. To determine how graduate students majoring in Home Economics perceive their Home Economics courses, a survey was conducted among the graduate students in 10 graduate schools of education, and a total of 131 accomplished questionnaires were used for data analysis. The results of the study are as follows. First, all 11 graduate schools aimed to retrain their teachers, enhance their professionalism, and produce home economics education experts. The Home Economics Education courses come in two strands; a teacher's course and a major course. Most of the schools require a total of 30 credits. All Schools lack professors. Only 3 graduate schools have a home Economics Department in the College of Education. All graduate schools are offering a teacher's course based on a teacher's certification system. In a major course, Home Economics education has the largest number of subjects, with Clothing and Textiles and Food and Nutrition being given greater emphasis, and Consumer Economics, Home Economics Management, Child Care, and Family and Housing Studies being given less emphasis. Second, they mostly regard the graduate school of education as producer of experts, followed by producers of teachers and teacher re-trainers. Those who were majoring in Home Economics Education in college, and the teachers, are more interested in teacher re-training, while the non-teachers and those who were not majoring in Home Economics Education are more interested in producing teachers. They are less satisfied with the operation of the graduate school of education. But they are generally satisfied with the Home Economics Education course. Graduate students registered the lowest satisfaction with a major course, especially experimental subjects. For a teacher's course, the graduate students who are not teachers exhibited higher satisfaction, whereas the teachers showed lower satisfaction. But teachers registered more satisfaction with the practical use of major subjects in the educational field, thinking that their major was a big help in their work at a school. As for what has to be improved with regard to the Home Economics Education course, many cited the necessity of securing a good faculty and expanding the major subjects.

The purpose of this study is to prepare basic data to reflect polar literacy education in the school curriculum. The perception about the polar regions, teaching experience, and polar-related cognitive and affective characteristics of teachers were investigated. The survey was conducted among 56 elementary, middle, and high school teachers from schools from 10 major cities and surrounding regions, based on their perceptions of the polar region, current teaching status, polar knowledge, and beliefs and attitudes toward polar region and climate change. Results showed that although teachers' polar information efficacy was low, they positively evaluated the status of educators in resolving polar and climate change problems, and prioritized global citizenship values over practical purposes. The experience of teaching polar region and climate change issues at schools varied across subjects and non-subjects, but showed a passive aspect in teaching development, such as wanting to be provided with consolidated learning materials. On the cognitive aspect, teachers revealed an ambiguous understanding of the mechanisms and processes by which polar change and climate influence each other. On the affective aspect, most teachers showed strong beliefs and attitudes for polar-related issues beyond the school level, but their behavior choices were relatively lower. Based on the results, we propose the following as recommendations: providing opportunities and materials to promote polar knowledge, discovering educational materials in various contexts to form values and attitudes, developing educational materials from polar research materials, identifying misconceptions about polar knowledge among students and teachers, strengthening elementary school teachers' polar literacy, and cultivating positive attitudes and values toward polar issues.

The aim of this study was to explore science teachers' perceptions of good science teaching. To this end, the Korean Teaching Observation Protocol (KTOP), which was developed for the purpose of observing and improving science teaching, was utilized. In the first survey, teachers were asked whether they thought each item in the KTOP was important for good science teaching, the extent to which they implemented these items, and the level of difficulty in implementing them. The second survey asked teachers what they believed to be the reasons and solutions for the KTOP items that they had responded as difficult to implement. The responses obtained from 63 teachers in the first survey and 35 teachers in the second survey were categorized based on the characteristics of the responses. The categorized contents were then summarized and discussed for their features. As a result, science teachers responded that all items in KTOP, except for one, are important for good science teaching. However, it was also shown that the level of execution was low in cases where implementation was difficult. For the 13 KTOP items that were considered important but difficult to implement and showed relatively low implementation level, many respondents (69%) attributed the reason to both students and teachers. However, the most common response (60%) was that the teacher should solve those difficulties. From this, it was found that understanding and supporting teachers, as well as enhancing their competencies, are more important for good science teaching than external factors. We hope that this research findings will help to better understand the specific difficulties that science teachers face in their classes and contribute to practical efforts that aim to address these challenges.

We have investigated the recognition for the gifted science education program of middle school students being educated at the local center for the gifted. We developed a questionnaire that includes items for contents of the program, learning environments, participation attitude, effects of the program and improvements, and consists of it5-point Likert items and related descriptive items. 161 students at the local centers for the gifted responded to the questionnaire. The total score was 3.70 on a 5-point Likert scale. The score of effects of the program was highest, learning environments was the lowest. Most of the students referred that the participation of the programs help their schoolwork because of schoolwork preparations & review, learning the process of the solving problem and principle. On the contrary, difficult contents and long lesson hours interrupted their schoolwork. Students recognized that the programs are mainly composed of students' self-activities and the role of teachers is subsidiary. The programs have a good effect on them to increase interest in science and creative thinking. It is necessary that the program be improved in lesson hours, contents of the program, school facilities, and full service.

In this paper, a case of deep learning artificial neural network education was studied for artificial intelligence literacy education for preservice teachers and incumbent teachers. In addition, through the proposed educational case, we tried to explore the contents of artificial neural network principle education that elementary, middle and high school students can experience. To this end, first, an example of training on the principle of operation of an artificial neural network that recognizes two types of images is presented. And as an artificial neural network extension application education case, an artificial neural network education case for recognizing three types of images was presented. The number of output layers was changed according to the number of images to be recognized by the artificial neural network, and the cases implemented in a spreadsheet were divided and explained. In addition, in order to experience the operation results of the artificial neural network, we presented the educational contents to directly write the learning data necessary for the artificial neural network of the supervised learning method. In this paper, the implementation of the artificial neural network and the recognition test results are visually presented using a spreadsheet.

This study investigated the condition of chemistry teacher's student competency assessment based on the inquiry report. To this end, an inquiry report was collected for chemistry teachers who took the training at two universities that conducted the 2020 first-class chemistry teacher training. The science subject competencies presented in NAEA analysis framework was used to analyze what kind of competencies teachers assess students through inquiry reports. A total of 63 chemistry teachers submitted inquiry reports, which were analyzed by competency, sub-element of each competency, and detail element to analyze the actual situation. As a result of the study, most chemistry teachers reflected their 'scientific inquiry and problem-solving ability' in their evaluation through inquiry reports. 'Ability to understand and apply scientific principles', which is mainly evaluated through paper-based evaluation, was partially used as confirmation of prerequisite learning at the beginning of the inquiry and the weight of evaluating 'scientific communication skill' was not large. In 'scientific inquiry and problem-solving ability' through inquiry report, 'design and conduct explorations', 'data analysis and interpretation' and 'drawing conclusion and suggesting solution' were mainly assessed. However, 'discover and recognize problems' and 'development and use of model' were hardly assessed.

The purpose of this study is to categorize specific factors and characteristics of positive science experience by qualitatively analyzing the positive science experience cases in the memories of pre-service elementary school teachers. For this purpose, 101 essays written by pre-service teachers on the theme of 'my enjoyable science class experience' were analyzed. The collected data were analyzed using an inductive analysis method, and as a result, the characteristics of positive science experience cases in the memories of pre-service teachers were categorized into 4 categories and 12 topic groups. Specifically, 'experience of exploratory activities using special materials', such as long-term raising and observation of animals and plants, experiments using edible materials, and using special experimental tools had a positive effect on scientific experience. In addition, 'experience of activities emphasizing scientific inquiry' such as emphasizing observation activities, experiments accompanied by clear experimental results, making activities, and using various materials also had a positive effect on science experience. In addition, 'student-centered activity experience' such as strengthening student autonomy, emphasizing collaboration between students, and performing science activities outside of the curriculum also had a positive influence on the science experience. Lastly, 'positive influence of teachers', such as teachers' encouragement and enthusiasm, helped to positively recognize science.
