The main goal of this study is to provide a practical help to teachers who want to practice Problem-Based Learning in mathematics for establishing and realizing PBL environment. This study also produces mathematics PBL Learning Model and Criteria to Judge to help practice and to vitalize PBL in mathematics. To solve the research topics, I reviewed theoretical issues related to PBL, which became theoretical bases of this study. And then, from the theoretical background, items of criteria to judge mathematical problems in mathematics PBL are abstracted. And, through checking on content validity by experts, criteria to judge mathematical problems in mathematics PBL are completed. Also, based on previous PBL models, learning model in mathematics PBL that takes characteristics of mathematics into account is suggested through case studies by observing, a qualitative research method, on PBL study to materialize it. This research is expected to help teachers who want to practice PBL in mathematics.

수학시간에 많은 학생들이 흥미를 갖고 능동적인 학습활동을 할 수 있도록, 실세계 상황의 과제가 제시된 소집단 협력학습, 토론활동 위주의 문제중심학습(PBL:Problem-Based Learning)을 고등학교의 수학교실에 적용한다. 이를 위하여 본고에서는 학습여건의 조성, 적합한 학습과제의 특성, 교사의 역할 등을 중심으로 살펴보고, 발전적인 PBL학습모형을 개발하여 교실 실제에 적용함으로써 고등학교 학생들의 정의적 영역의 태도 변화에 미치는 영향을 살펴보고자 한다.

This study is to setup a mathematics PBL model that is right for elementary students. PBL models are developed and applied to actual courses and analyzed. So, a specific plan and practical understanding of PBL mathematics textbooks will be presented. But in order for this to happen, first the mathematics PBL model, that can realize 7th revised curriculum's goal, needs to setup and divided into knowledge, skill and attitude domains. Through this study, the general PBL model and the PBL model appropriate for elementary mathematics was amended and supplemented, this was then applied to courses and analyzed, and the below conclusions were realized. First, mathematical idealization stage is needed for mathematical PBL model. Since an elementary student is shortcoming in problem understanding and mathematical activity, a middle step that allows the student to understand the problem situation mathematizing and find a solution mathematically is desperately needed. Therefore, in this study, we named it the mathematical idealization stage and had it setup. Second, a mathematics information collection stage needs to be prepared for a successful PBL. Through this stage, the students will have an opportunity to gather the necessary information needed and restructure it to solve the problem. Third, the organization stage in mathematical PBL model needs to be strengthened. PBL is not just completed, through the best use of mathematics subject matter to solve the problem. Organization time is needed to allow the students to grow to a more deepened and advanced level. In conclusion, there is significance in providing a specific plan for mathematical PBL model, which can be seen through this study on applying and analyzing elementary mathematics and appropriate PBL models.

The importance of algorithm education has been emphasized for creative problem-solving capability. Especially, algorithm teaching materials related with mathematics and science are under development to enhance logical thinking. However, there are not enough teaching-learning models applicable in the field of education. Therefore, this paper proposed a teaching-learning model for effective algorithm education. The teaching-learning model reflects two characteristics : an algorithm learning process is spiral, and algorithm education is based on logical thinking. Furthermore, a survey was conducted for students' satisfaction, and the result was a mixed teaching-learning model with PBL, SDL, and peer tutoring. Based on the proposed model, examples of classes for mathematics and science are suggested to show the feasibility of effective algorithm education.
