In this study, we tried to suggest a meaningful teaching method that is a mathematical thinking-oriented. After referring to the recent trend of mathematics education, we examined the direction that school mathematics should go. Next, we considered previous studies that deals with teaching methods focusing on the mathematical thinking. On the basis of the above examination, we accomplished case studies that aims at mathematical thinking-oriented teaching. And we explained that these case studies reflects the key points didactics of mathematics such as the education of ‘open mathematics’, constructivism etc. Finally, we proposed the necessity of mathematical thinking-oriented teaching in the current state of school mathematics.

본 연구는 최근 2000년대를 향한 세계 여러 나라의 수학 교육과정 개정의 결과들을 살펴봄으로써 우리나라 제 7차 수학 교육과정 개정 노력에 대한 반성적 고찰을 위한 기초 자료를 마련하는 데 그 목적이 있다. 이러한 목적을 달성하기 위하여 수학교육의 오랜 전통을 지녔으나 국내에 잘 알려지지 않은 독일의 수학 교육과정의 구성체제와 구성내용을 Nordrhein-Westfalen 주를 중심으로 구체적으로 살펴보고, 우리나라 수학교육과정과 그 특징을 비교하였다 마지막으로 앞에서 살펴본 내용을 바탕으로 우리나라 수학교육과정의 발전적 고찰을 위한 시사점을 논하였다.

In recent years, coding education has been globally emphasized and the Free Semester System will be executed to the public schools in Korea from 2016. With the introduction of the Free Semester System and the rising demand of Computational Thinking (CT) capacity, this research aims to design 'learning environment' in which learners can design and construct mathematical objects through computers and print them out through 3D printers. Furthermore, it will design learning mathematics by constructing the figurate number patterns from 'soma cubes' in the playing context and connecting those to algebraic and combinatorial patterns, which will allow students to experience mathematical connectivity. It is expected that the activities of designing figurate number patterns suggested in this research will not only strengthen CT capacity in relation to mathematical thinking but also serve as a meaningful program for the Free Semester System in terms of career experience as 3D printers can be widely used.

Technical high school aims at educating students to acquire fundamental skill and technology required for being competent technicians, to be creative in adjusting themselves to the changing industrial society, and to do self-realization and find their ways toward the future on their own. To attain that goal and maximize learning effect, mathematics education is very important as prerequisite learning for technical subjects, as most technical courses in technical high school are basically based on mathematics. The purpose of this study was to discuss how mathematics education could be successfully linked to technical courses in an attempt to make it function properly as prerequisite learning for major subjects and facilitate students' technical learning. For that purpose, what problems the mathematics components of major subjects and the curriculum had was examined and the way to offer better education was presented. And there are some suggestions regarding mathematics education: First, technical mathematics should be newly inserted into technical high school curricula to help students learn major subjects in more efficient way. Second, most technical high schools are expected to just require tenth graders to complete a 10-stage mathematics course. In that case, they might find difficulties in learning major subjects when they are in their 11st and 12th grade. The curriculum should be designed to have 11st and 12th graders take mathematics education. Third, many students find a job after graduation, but the growing number of students go on to university to receive more education in the same field. Accordingly, there is a need to enlarge continuous progress plan, rather than completion-type one, to make students well-grounded technically. And mathematics should be taught in more classes as prerequisite subject for major courses. Fourth, mathematics elements necessary for each major subject should be outlined and announced to schools so that they could reorganize mathematics and major courses appropriately.

This research aims to analyse implementation effects of the Real mathematics Education(RME) in the high school probability and statistics For this aim, two research questions are estabilished as fellows. (1) Is there any improvement of mathematical achievement in the class by RME's lecture than in the class by the mathematics text's lecture ? (2) Is there any improvement of mathematisation level in the class by RME's lecture than in the class by the mathematics text's lecture ? Before answering the above research questions, RME.`s lecture notes and ordinary lecture notes are developed based on the learning principles of the RME and mathematics textbook respectively. Two classes are randomly chosen from a high school located at midium size city and assigned as the experimental group and the control group respectively. The 20 hours of the RME's lecture notes is administerd to the experimental group and the 20 hours of the odinary lecture notes is administerd to the control group. It is shown that the class by RME's lecture is more effective in both of the mathematical achievement and the mathematisation activity than the class by the ordinary lecture. Hence, it is urged from the result of this research that RME's context will be developed and the RME's lecture will be implemented in the other field of high school mathematics.

모든 학습에서 시간은 매우 중요한 자원이다. 수학학습에서는 더욱 더 그러하다. 본 논문에서는 수학학습에서 시간이 어떻게 사용되며 이와 관련된 수학학습과의 관계를 조사 분석하였다. 학습자에게 주어지는 학습 시간은 귀중하고 가치 있게 또한 의미 있는 시간을 영위하도록 학부모나 교사들은 배려해야만 한다. 학습자는 학습의 진정한 주체가 되어 자율적이고 연속적이며 끊임없는 진정한 수행이 되도록 노력해야 한다. 누구에게나 물리적 시간은 같지만 어떻게 보내느냐에 따라서 그 질 및 가치는 매우 다르기 때문이다. 이러한 맥락에서 본 논문이 수학학습의 질을 높이는데 기여하는데 그 의의를 두고자 한다.

This study aims to establish and analyze a mathematical model for the transmission dynamics of male adolescent smoking and to determine an optimal control strategy to reduce male adolescent smoking. We consider three groups in the population: smokers, non-smokers, and temporary nonsmokers. In our model to which optimal control theory was applied, the number of smokers decreased sharply and the number of non-smokers increased significantly. Our simulation results under various control scenarios reveal that integrated control measures(such as prevention, education, and treatment) may be necessary to reduce the growth rate of adolescent smoking. Moreover, we concluded that efforts to encourage current smokers and temporary quitters to quit should be sustained longer than efforts to reduce the rate at which nonsmokers become smokers through smoking prevention education.

스토리텔링 기법을 수학 교과서에 적용할 때, 스토리를 전개하는 방법에 따라 늘어나는 학습시간을 효율적으로 조절하는 것은 중요한 문제이다. 특히 고교과정의 수학은 중학교 과정과 비교하여 소화하여야 할 수학적 지식의 양과 질이 차별화 되므로, 각 단원에 적절한 스토리텔링 기법을 개발할 필요가 있다. 본 연구에서는 고등학교 미분적분학 단원을 중심으로, 공학적 도구를 활용하여 수학 문제 풀이에 요구되는 계산 시간을 줄여 개념학습 시간을 충분하게 확보하는 스토리텔링 교과서 개발 사례를 제시한다.

This study aims to explore mathematics teachers' pedagogical design capacity. For this purpose, we googled and collected 327 lesson plans for middle-school mathematics and investigated how mathematics teachers plan and design their mathematics lessons through the format and structures, objectives and mathematical tasks, anticipation for students' thinking, and assessment and technology use. The findings from the data analysis suggest as follows: a) all the lesson plans are structured in a very similar way; b) the lesson plans seem to be based on the textbooks exclusively, that is, the mathematical tasks and flow is strictly followed and kept in the lesson plans in the way the textbooks suggested; c) the lesson plans do not include any evidence of what teachers anticipate for students' thinking and would do to resolve the students' issues; and d) the lesson plans do not contain any specific plans to assess students' thinking processes and reasoning qualitatively, and not intend to use technology in order to promote effective teaching and meaningful understanding.
