The recent Korean mathematics curriculum stresses to teach mathematics focusing on mathematical process composed of problem solving, reasoning and communication. To be successful in applying the rationale of the process-focused mathematics education, the assessment practice in classrooms should be also centered on mathematical process. In this study we conducted a large-scale survey on teachers' perspectives about the process-focused mathematics assessment. First, we surveyed teachers' opinion on current assessment practices in school mathematics related to regular school exams and performance assessments. Second, we investigated teachers' perception on mathematical process components such as problem solving, reasoning, and communication regarding how they should be assessed. Finally, we examined the difference of teachers' opinion according to their teaching experience, city size, and the type of school. Based on the results, we discussed implications for mathematics assessment and process-focused mathematical assessment.

This study evaluated middle school teachers' perceptions and demands for changing in Food and Nutrition sections of Home Economics and also identified variables related. Teachers expressed unfavorable attitudes to the usefulness of contents in real life, and clearly perceived the importance of a basic theory of nutrition in general and adolescency among 12 items related with Food and Nutrition section. Most of the teachers pointed the way in which textbooks are described and organized were heavily oriented into lectures, more than creative discussion and diverse activities. The insufficient materials for teaching-learning were also pointed as barriers in improving the level of quality of Food and Nutrition sections in middle school Home Economics textbooks. Teachers had strong beliefs that textbooks, based on 7th National Curriculum, should be changed and improved not only in contents but also in organizations. Cognition of teachers on the appropriateness, in terms of quantity of contents, competitiveness for developing students' capacity. level of quality, and interests among students and teachers, was consistent and independent indicator of their needs for changing. These results suggest that the next textbook should include more materials for teaching-learning designed to expand students' capacities and develop critical thinking skills. Effective educational curriculum should integrate sufficient activities together with detailed instructions. Creative activities may allow students to learn and connect these activities to the contents in Food and Nutrition section of Home Economics curriculum.

In this study, we investigated teachers' experiences in teaching with the science museum as well as their confidence, their perceptions, educational needs, and their willingness to practice the instructions using science museum. A survey was administered to 225 elementary and secondary school teachers. The analyses of the results revealed that few teachers had training for the instructions using the science museum and not many teachers had experience in teaching with the science museum. Many teachers were also found to have low confidence in teaching with the science museum. Although the teachers had a relatively good understanding of the educational effects, nature and teaching strategies for the instructions using the science museum, they tended to apply the formal views on science teaching/learning to learning with the science museum. The levels of willingness to use the science museum in their instructions and educational needs of the instructions using the science museum were high. They wanted the information about practical aspects to use in the instructions using science museum most. Educational implications of these findings are discussed.

A school library is where students develop their skills to cope with future uncertainty and can utilize various information materials to build their capability and response abilities to changes. Teachers' perception is crucial as their guidance is essential for the student to use the school library. Most studies, however, focused on quantitative measurement of the importance of the teachers' perception as an external environment, and there is a lack of specific categorization of different types of perceptions on the role of the school library. This study aims to examine types of perceptions about the school library among elementary school teachers. To do so, this study used Latent Profile Analysis (LPA), a person-centered approach, to identify teachers' complex perceptions about the role and importance of the school library, which were difficult to review in previous studies, and the teachers' most representative types of perceptions. Based on the findings from the above, this study is meaningful in proposing customized measures to operate and promote the school library depending on teachers' perceptions.

The purpose of this study is to investigate elementary students' perception on science-related career and teachers' perception on science-related career education. The subjects of this study were 196 5^th and 6^th elementary students and 100 elementary teachers. The results show that 28% of the students desire to have science-related career. More Boys desire science-related careers than girls, and more students with higher level of perception in their science achievement also do than lower level students. The reason students did not desired science-related career were that they were not interested in science and did not have fun in science. Students' perceptions in the factors of science-related career choice were mostly negative except socio-cultural factors. The results of teacher's perception show that 42% of the teachers conducted science-related career education. A lot of teacher did not conduct science-related career education since they perceived the career education were not necessary or important. Students' negative perception on the factors of science-related career choice and the teachers' low perception on necessity of science-related career education can negatively influence students' science-related career choice. The more efforts were required in order to increase positive perception on science-related career.

The purpose of this study was to analyse the teachers' perception about the applying the history of Korean science in elementary science class. To research the educational value and application of the history of Korean Science in Elementary science class, 202 teachers of elementary school were asked to reply the questionnaire of 5-point Likert scale and Elementary science textbooks were analysed. The results of this study indicated that 4th grade science textbooks does not include the history of Korean Science, and a majority of teachers perceived positively about its educational value. 4th grade teachers showed relatively negative perception on the educational value of the history of Korean Science and Elementary school teachers were very positive about including it as the main classes of the curriculum.

This study was conducted to find out how many secondary school science teachers are aware and ready to implement new science curriculum as well as its revision process. For the purpose of this study, teachers had been asked to fill in a questionnaire. The results showed that teachers' overall understanding and readiness was low and that the implementation of new curriculum was a burden to a large number of teachers. Some teachers even expressed a negative opinion. Furthermore, it turned out that teachers didn't have an important role in revising the curriculum as a only small number of teachers participated. So, the second questionnaire and interviews were provided in order to ask for various opinions as to how new science curriculum should be communicated to schools and when school teachers should participate in the revision of curriculum, along with their role and participation methods.

As the era of solving various and complex problems in the real world using artificial intelligence and big data appears, problem-solving competencies that can solve realistic problems through a mathematical approach are required. In fact, the 2015 revised mathematics curriculum and the 2022 revised mathematics curriculum emphasize mathematical modeling as an activity and competency to solve real-world problems. However, the real-world problems presented in domestic and international textbooks have a high proportion of artificial problems that rarely occur in real-world. Accordingly, domestic and international countries are paying attention to the reality of mathematical modeling tasks and suggesting the need for authentic tasks that reflect students' daily lives. However, not only did previous studies focus on theoretical proposals for reality, but studies analyzing teachers' perceptions of reality and their competency to reflect reality in the task are insufficient. Accordingly, this study aims to analyze in-service mathematics teachers' perception of reality among the characteristics of tasks for mathematical modeling and the in-service mathematics teachers' competency for designing the mathematical modeling tasks. First of all, five criteria for satisfying the reality were established by analyzing literatures. Afterward, teacher training was conducted under the theme of mathematical modeling. Pre- and post-surveys for 41 in-service mathematics teachers who participated in the teacher training was conducted to confirm changes in perception of reality. The pre- and post- surveys provided a task that did not reflect reality, and in-service mathematics teachers determined whether the task given in surveys reflected reality and selected one reason for the judgment among five criteria for reality. Afterwards, frequency analysis was conducted by coding the results of the survey answered by in-service mathematics teachers in the pre- and post- survey, and frequencies were compared to confirm in-service mathematics teachers' perception changes on reality. In addition, the mathematical modeling tasks designed by in-service teachers were evaluated with the criteria for reality to confirm the teachers' competency for designing mathematical modeling tasks reflecting the reality. As a result, it was shown that in-service mathematics teachers changed from insufficient perception that only considers fragmentary criterion for reality to perceptions that consider all the five criteria of reality. In particular, as a result of analyzing the basis for judgment among in-service mathematics teachers whose judgment on reality was reversed in the pre- and post-survey, changes in the perception of in-service mathematics teachers was confirmed, who did not consider certain criteria as a criterion for reality in the pre-survey, but considered them as a criterion for reality in the post-survey. In addition, as a result of evaluating the tasks designed by in-service mathematics teachers for mathematical modeling, in-service mathematics teachers showed the competency to reflect reality in their tasks. However, among the five criteria for reality, the criterion for "situations that can occur in students' daily lives," "need to solve the task," and "require conclusions in a real-world situation" were relatively less reflected. In addition, it was found that the proportion of teachers with low task development competencies was higher in the teacher group who could not make the right judgment than in the teacher group who could make the right judgment on the reality of the task. Based on the results of these studies, this study provides implications for teacher education to enable mathematics teachers to apply mathematical modeling lesson in their classes.

The purpose of this study was to investigate perceptions of high school students and science teachers about high school fusing science. Science teachers and high school students perceived that high school fusing science was related to various areas and they preferred to be taught separately from each area. Science teachers perceived that high school fusing science improved the understanding in the area of scientific common knowledge, advanced technology, and the history of science, but neither scientific writing nor discussion were actively involved. It also didn't contribute to the enhancement of scientific thinking and communication skill. Especially, high school students believed that they were more interested in science through fusing science. On the other hand, teachers believed that this high school fusing science might not impact student's learning and generate negative perception. Science teachers and students perceived that they were more interested in fusing science because it was combination of many areas in science. They also perceived that contents in fusing science were more related to their daily life.

This study investigated the change of pre-service science teachers' epistemological views of education according to the stages of the field education programs application. For this study, surveys and interviews were carried out threes times before and after participation through participant observation of classes and teaching practices. All data recorded and collected of 28 pre-service science teachers who had answered entire surveys were transcribed and analyzed. The conclusion is as follows; before the participant observation of classes, the pre-service science teachers had views of traditional education affected by epistemology of objectivism. After the participant observation of classes, the views of traditional education increased due to in-service teachers that showed teaching methods through the course of the participant observation. However, it was changed significantly into the views of modern education affected by epistemology of constructivism through the course of the teaching practices. Based on the conclusions of this study, it was identified that the field education programs might have both positive and negative influence on the change of the views of education for the pre-service science teachers. Therefore, Pre-service science teachers should have a opportunity to intensify of constructivism epistemological views of education through the field education programs. The teacher training institutions have to provide systematic and organic cooperation with schools.
