Mathematical creativity is essential in school mathematics and mathematics curriculum and ensures the growth of mathematical ability. Therefore mathematics educators try to develop students' creativity via mathematics education for a long time. In special, 2011 revised mathematics curriculum emphasizes mathematical creativity. Yet, it may seem like a vague characterization of mathematical creativity. Furthermore, it is needed to develop the methods for developing the mathematical creativity. So, the goal of this paper is to search for teaching and learning models for developing the mathematical creativity. For this, I discuss about issues of mathematical creativity and extract the factors of mathematical creativity. The factors of mathematical creativity are divided into cognitive factors, affective factors and attitude factors that become the factors of development of mathematical creativity in the mathematical instruction. And I develop 8-teaching and learning models for development of mathematical creativity based on the characters of mathematics and the most recent theories of mathematics education. These models make it crucial for students to develop the mathematical creativity and create the new mathematics in the future.

The purpose of this study is to investigate the changes of students' modeling ability in terms of 'meta-modeling knowledge' and 'modeling practice' through co-construction of scientific model. Co-construction of scientific model instructions about astronomy were given to 41 middle-school students. The students were given a before and after instruction modeling ability tests. The results show that students' 'meta-modeling knowledge' has changed into a more scientifically advanced thinking about models and modeling after the instruction. Students were able to be aware that 'they could express their thoughts using models', 'many models could be used to explain a single phenomena' and 'scientific models may change' through co-construction modeling process. The change in the 'modeling practice' of the students was divided into four cases (the level improving, the level lowering, the high-level maintaining, the low-level maintaining) depending on the change of pre-posttest levels. The modeling practice level of most students has improved through the instruction. These changes were influenced by co-construction process that provides opportunities to compete and compare their models to other models. Meanwhile, the modeling practice level of few students has lowered or maintained low level. Science score of these students at school was relatively high and they thought that the goal of learning is to get a higher score in exams by finding the correct answer. This means that students who were kept well under traditional instruction may feel harder to adapt to co-construction of scientific model instruction, which focuses more on the process of constructing knowledge based on evidences.

This research analyzed mathematical discourse of the students in an RME-based differential equations course at a university in order to investigate the social transformation of the students' conceptual model of differential equations. The analysis focused on the change in the students' use of conceptual metaphor for differential equations and pedagogical factors promoting the change. The analysis shows that discrete and quantitative conceptual model was prevalent in the beginning of the semester However, continuous and qualitative conceptual model emerged through the negotiation of mathematical meaning based on the inquiry of context problems. The participation in the project class has a positive impact on the extension of the students' conceptual model of differential equations and increases the fluency of the students' problem solving in differential equations. Moreover, this paper provides a discussion to identify the pedagogical factors Involved with the transformation of the students' conceptual model. The discussion highlights the sociocultural aspect of teaching and learning of mathematics and provides implications to improve teaching of mathematics in school.

The purpose of this study was to explore factors that affected the satisfaction of students' experiences in an education course, with the educational method and educational technology designed with a blended learning strategy. Blended learning is currently recognized as a good solution for the problems posed by both online and face-to-face learning, because it has features like flexibility and accessibility by using tools supporting both individualization and socialization. This study is one case that illustrates how blended learning can be applied at the university level. Subjects were 56 students who had participated in the class and responded to the survey questions. The gathered data were analyzed by using Factor Analysis and the Structural Equation Model. Based on the results of Factor Analysis, data revealed 5 factors: learning motivation, previous experience, ability to use information & technology, capability of self-regulated learning, and learning satisfaction. The results of the Structural Equation Model revealed causal relationships among the aforementioned factors as follows: (a) there was a statistically meaningful causal relationship between "learning motivation" and "capability of self-regulated learning", (b) there was a statistically meaningful casual relationship between "previous experience" and "capability of self-regulated learning", and (c) "capability of self-regulated learning" directly affected "learning satisfaction".

This study investigates maker pedagogy as learning method with graduate students. The exemplary maker pedagogy instructional model in this study is intended to enhance student's research competence. This study examines how the teacher designs and implements maker pedagogy instructional model, and what students have experienced in conduction research project. students provide evidence that they have improved their competence to raise research questions, to make use of research methodology. Their learning experience depends on whether they are heterogeneously grouped or homogeneously grouped in terms of intellectual ability, research experience, etc. Additionally, students suggest that the teacher needs to administrate the learning process regularly, to build up an interdisciplinary network to provide students knowledge and methodologies needed for conducting research, and to create learning environment where each student is possibly enriched with individual accountability and responsibility on each own learning process. In conclusion, this study provides several suggestions for more valuable maker pedagogy instructional models in graduate class.

This study explored the possibility of using visual models in teaching proportional reasoning based on the review of previous studies. Many studies on proportional reasoning emphasize that students tend to simply apply formal procedures without understanding the meaning behind them and that using visual models may be an alternative to help students develop informal strategies and proportional reasoning. Given these, we re-constructed and implemented the unit of a textbook to teach sixth graders proportional reasoning with ratio table, double number line, and double tape diagram. The results of this study showed that such visual models helped students understand the meaning of proportion, explore the properties of proportion, and solve proportional problems. However, several difficulties that students experienced in using the visual models led us to suggest cautionary notes when to teach proportional reasoning with visual models. As such, this study is expected to provide empirical information for textbook developers and teachers who teach proportional reasoning with visual models.

현재 웹 코스웨어의 대부분은 하이퍼텍스트 문서들간의 비선형적인 연결에 의한 학습 방식을 채택하고 있으나, 이는 단순한 페이지 링크형 학습으로서 그리 커다란 교육 효과를 발휘하기에는 어렵다는 한계를 맞이하고 있다. 이러한 상황에서 다중 학습자가 동기적으로 참여하는 시뮬레이션 게임 방식은 웹 코스웨어의 현재 한계를 뛰어넘을 수 있는 하나의 교수·학습 모델이 될 수 있을 것으로 기대된다. 이에 본 논문에서는 다중 학습자가 동기적으로 참여하는 시뮬레이션 게임 방식의 웹 코스웨어에 대한 수업 모델을 제안하고 있다. 이 수업 모델은 Atkinson의 체제적 접근 방식의 게임 설계, Alessi와 Trollip의 시뮬레이션의 구조와 절차, Reigeluth와 Schwartz의 시뮬레이션에서의 학습자 역할에 대한 분석 연구를 기반으로 설계하였다.

The purpose of this study is to design and implement an instructional model for flipped learning of programming class. Because a programming process requires a high level of abstract thinking with a good understanding of a programming language, many students have difficulty in programming. For this characteristic of programming, it is not easy to effectively achieve learning goals of programming lesson by lecturing grammatical elements of a programming language and the following examples in a limited class time. In order to overcome these problems and to make effective programming lessons, we designed an instructional model based on flipped learning. Especially, in this study, we analyzed learners' difficulties in programming learning and errors that occurred in actual programming process for designing the instructional model. As a result of applying this model to the class, it was found that the students were generally satisfied with the lesson by having positive communication with other students in the classroom and actively participating in the learning.
