In this paper, we apply mathematising activities to geometry contents of corrent in middle and high school in order to actualize learning and teaching through Freudenthal's, Piaget's, and Van Hieles's mathematising among many theories affecting teaching and learning methods. Learners find out mathematical idea through the activities of mathematising that interprete mathematical problemm. And we derive mathematic through the experience of vertical mathematising that expresses it. Based on it, Freudenthal's progressive mathematising process, etc are used in doing the activities of applicative mathematising.
The purpose of this study was to investigate the experience of pre-service mathematics teachers who attended at a university course combined with teaching practicum based on design thinking process to identify the change of their awareness of its activities. For the research, 8 pre-service mathematics teachers participated in a mathematics major course, consisting of 5 phases of design thinking formed by Stanford d.school. In the end of the course, qualitative data were collected through individual and focus group interviews and the course activities. By data analysis, the results of this study were as follows. Firstly, the participants' perspectives of design thinking activities were changed from the difficulty and ambiguity of its activity in the beginning of the process to positiveness with competence of solving authentic problem in terms of teaching practicum over time. Secondly, the participating pre-service teachers emphasized that design thinking activities helped them prepare well teaching practicum and raise understanding of students they met in the school fields. Thirdly, some research participants went through the difficulty in utilizing their products drawn from 4th phase (prototyping) of design thinking process depending on the acceptance of their guidance teachers. Fourthly, the research participants also pointed out that the design thinking was a significant activity in that they learned how to understand and communicate with their students and how to collaborate with team members and it gave an insight about the preparation for a class. Through these results, this study identified the possibility of using the design thinking process for pre-service mathematics teachers' teaching practicum. In addition, the research put forward some implications for better use of design thinking in teacher education.
Interest is acknowledged to be a critical motivational variable that influences learning and achievement. The purpose of this study was to investigate the interest of the elementary students when free inquiry activities were performed through a brain-based evolutionary scientific teaching and learning model. For this study, 106 fifth grade students were chosen and performed individually free inquiry activities. The results of this study were as follows: First, after free inquiry activities, as to free inquiry science related attitude, a statistically significant difference was not observed. But they came to have positive feelings about the free inquiry. Especially students marked higher mean score in openness showed consistency in sub-areas of free inquiry science related attitude. Second, students had interests in various fields, especially they had many interests in area of biology. They chose inquiry subjects that seems to be easily accessible from surrounding and as an important criterion of free inquiry they thought the possibility that they could successfully perform it. And students who belong to the high level in the science related attitudes and academic achievement diversified more topics. Third, most of students failed to further their topics. However, the students who specifically and clearly extended their topics suggested appropriate variables in their topics. On the other hand, students who couldn't elaborate their topics were also failed to suggest further topics and their performance of inquiry was more incomplete. In conclusion, the experiences of success in free inquiry make the science attitude of students more positive and help them extend their inquiry. These results have fundamental implications for the authentic science inquiry in the elementary schools and for the further research.

The purpose of this study is to examine the effect of small group inquiry activities using IIM on the science process skills and scientific attitudes of students in higher elementary grades. To verify research problems, the subjects of this study were fifth-grade students selected from two classes of an elementary school located in Busan : the research group was composed of thirty students who participated in small group inquiry activities using IIM teaching model situation, and the other was composed of thirty students(comparative group) who participated in a teacher map- based learning situation. For six weeks, the small group inquiry activities using IIM were executed in the research group, while the teacher-map based instruction was conducted in the comparative group Test showed the following results: First, the research group showed a significant improvement in their science process skills compared to the comparative group. Second, the research group did not show a significant improvement in their scientific attitudes compared to the comparative group. In conclusion, small group inquiry activities using the IIM teaching model was more effective than the teacher map-based teaching model on science process skills. However, since the study has a limit on the object of the study and the applied curriculum, the additional studies need to be conducted with an extended comparative group and curriculum.

This study aims to examine the effects of college students' teaching-friendly learning activities on college life adaptation, and to examine whether these effects differ according to learner characteristics. To this end, 214 people who participated in the learning program of universities located in G area in the first semester of 2022 were targeted. In order to find out the effect of teaching-friendly learning activities on college students' adaptability to college life, frequency analysis, response sample t-verification, and one-way analysis of variance (one-way Anova) were conducted using SPSS 20.0. The results are as follows. First, it was found that teaching-friendly learning activities significantly increased the scores of academic adaptation, emotional adaptation, and social adaptation in college life adaptation. Second, there was no difference in adaptation to college life according to college. Third, The score of the level of attachment to universities was found to be higher in the female group than in the male group. Fourth, as a result of the analysis according to the grade, it was found that the third-grade group had a high level of attachment to universities.

The purpose of this research is to analyse the composition of theories and practical activities in clothing and textiles in Technologyㆍ Home economics textbooks in the 7th National Curriculum and find out learning requirement of students in the area. For this research, a survey was conducted using questionnaires with 280 high school students living in Daegu and the rate of response was 78.9%. The results of this study are as follows. 1. After analysing the curriculum of Practical Arts subject in elementary school and Technology´ Home Economics subject in secondary school, we could find out that more emphasis is put on practical activities in elementary school and high school. On the other hand, theories are considered more important in middle school. 2. Students have similar preference both for theories and for practical activities as a way of learning in class and show positive responses to practical activities unless they´re giving too much pressure as a part of performance test. 3. According to their learning requirement. several teaching-learning contents in clothing and textiles in Technology Home economics are selected such as materials,. clothes designs, how to set dressed well, how to make a reasonable purchase on clothes, and the process of manufacturing various clothes, etc. Therefore it would be desirable to provide the students with the learning opportunity to the extent where even the students who haven´t chosen the selected-advanced course can take part in class actively.
When mathematicians solve the new problems, they present the solutions to their colleagues for getting the approval. If the solution is accepted, it will be theorems. This phenomenon also happens to classrooms in elementary and secondary school. That is main reason to emphasize mathematical communication activities in mathematics education. This study is aimed to develop teaching and learning model for the improvement of mathematical communication ability, applicate the teaching and learning model to two groups and analyze for mathematical thoughts. This study is a case study of 3rd grader's activities. Eight students, four are group applied the teaching and learning model and four are traditional group. The results have been drawn as follows: First, students in the teaching and learning model group induced richer interactions for student's understanding and investigation when we compare to those of traditional group. Second, students in the teaching and learning model group have the chance to explain their thoughts. And we can observe students to clear on their thought through speaking and discussing. This model makes students to enhance organizing, forming and clearing in their mathematical thoughts and is effective to estimate of students thought for teacher.
