  • The purpose of the study were to analyze MathThematics textbooks and Korean middle school mathematics and to investigate the difference among the textbooks in the view of mathematical communication. According to the results, the textbook developers made a variety of efforts to develope students' mathematical communication ability. Students were encouraged to communicate with others about their mathematical ideas or problem solving processes in words or writing by means of discussion, oral report, presentation, journal, etc. MathThematics textbooks provided student self-assessment opportunity to improve student performance in problem solving, reasoning, and communication. In communication assessment, students can assess their use of mathematical vocabulary, notation, and symbols, the use of graphs, tables, models, diagrams and equation to solve problem and their presentation skills. The assessment activities would make a positive impact on the development of students' mathematical communication ability. MathThematics textbooks provided a variety of problem situation including history, science, sports, culture, art, and real world as a topic for communication, however, the researcher found that some of Korean textbooks depends heavily on mathematical problem situations.

  • The ultimate goal of environmental education is to train the civilian who positively participates in solving environmental problems. To do above, not only accurate knowledge but also right value about environmental problems are needed. It is reasonable decision making that choose the first of all alternatives to solve the problems by accurate knowledge and right value of an individual. Teaching reasonable decision making in environmental education is related to raise the participant civilian toward regional environmental problem solving Simulation game helps that students have a opportunity to practice decision making skills about regional problems and give self-confidence to their decision making ability. So, the aim of this study is to present simulation games which is fit to elementary environmental education. The first one is for group decision making, the second one is for individual decision making. These can make a conclusion, winner and loser of games. But last one is open-ended game and aims to make explicit a variety of opinions, issues and conflicts to problem.

  • In mathematical modeling tasks, where students are exposed to model-eliciting for real and open problems, students are supposed to formulate and use a variety of mathematical skills and tools at hand to achieve feasible and meaningful solutions using appropriate problem solving strategies. In contrast to problem solving activities in conventional math classes, math modeling tasks call for varieties of mathematical ability including mathematical creativity. Mathematical creativity encompasses complex and compound traits. Many researchers suggest the exhaustive list of criterions of mathematical creativity. With regard to the research considering the possibility of enhancing creativity via math modeling instruction, a quantitative scheme to scale and calibrate the creativity was investigated and the assessment of math modeling activity was suggested for practical purposes.

  • This paper is devoted to the parallelism of a numerical matrix eigenvalue problem. The eigenproblem arises in a variety of applications, including engineering, statistics, and economics. Especially we try to approach the industrial techniques from mathematical modeling. This paper has developed a parallel algorithm to find all eigenvalues. It is contributed to solve a specific practical problem, a vibration problem in the industry. Also we compare the runtime between the serial algorithm and the parallel algorithm for the given problems.

  • This is the study on a teaching method for improving problem-solving ability in mathematics. If this method is performed step by step in solving problems, learners can approach problems in a variety of ways. This step-by-step teaching method will create some changes among learners. The purpose of this experiment was to determine what effects resulted from this method, especially which effects arose in the affective areas of learning math. For the experiment, learning materials were divided into 73 parts. And the subjects, who are low-leveled and have negative attitudes towards mathematics, were divided into two groups. One group was exposed to this method for four months (treatment group), and the other group(control group) was not. According to the result, though there were few changes, the treatment group came to be more interested in math than before and also negative attitudes towards math were reduced gradually, as compared with the control group. In this study, three factors were investigated: interest in math, attitudes toward math, and learning -achievement in math. Significant changes were found in two factors: interest in math and learning-achievement in math. No significant changes were found in the area of attitudes towards math. In conclusion, if this method is adopted and performed regularly, it is likely that the problem-solving skills will be improved and the negative attitudes towards math will be reduced.

  • Background: The purpose of this study was to develop a problem-based learning model for orthopedic manual physical therapy. A problem-based learning (PBL) model for orthopedic manual physical therapy developed from PBL module of Jeju C university (Halla-Newcastle PBL Center). A summary of this study is as follows: 1) PBL model is comprised of a class of 30 students, operated small group as of 4~5 students. 2) PBL is suggested a scenario of clinical case, induced variety reaction through group discussion and presentation. 3) PBL is occurred wide variety learning through group work activity and self-directed learning. 4) The tutor as a facilitator is played a guide for group discussion, work activity and team learning. 5) The evaluation for PBL is performed such as student self-evaluation, group activity evaluation, individual presentation, and practice. This model is considered wide variety learning through team learning and self-directed learning by clinical reasoning and problem solving for musculoskeletal clinical case. We suggest problem based learning for the education of orthopedic manual physical therapy in which the learners are very interested in and has the effective outcome.

  • 4차 산업혁명시대에 필요한 인재는 특정 학문에 종속되는 것이 아니라 여러 학문들을 융합할 수 있어야 한다. 초등학생들의 경우에 다양한 변화의 가능성이 있기 때문에 융합적인 사고를 갖는 것이 중요하다. 따라서 초등학교 영재를 선발할 때에도 융합 영재 학생들을 선발하고 있다. 본 연구에서는 융합 영재 학생들을 선발할 때에 창의적인 문제 해결력, 서류 평가, 면접 요소들이 학생 선발에 어떤 영향을 미치는지 알아본다. 연구 결과 창의적 문제해결력이 선발에 미치는 영향력이 가장 높다. 5학년의 경우에는 창의적인 문제 해결력과 서류 평가가 선발에 영향을 미치고, 4학년의 경우에는 창의적인 문제 해결력과 면접이 선발에 영향을 미치고. 여학생들은 창의적인 문제해결력과 서류 평가가 선발에 영향을 미친다는 것을 알 수 있었다. 그룹별로 차이를 분석한 결과, 성별에서는 서류 평가에서 성별로 차이가 있었고, 학년별 유의미한 차이점이 없다는 것을 알 수 있었다.

  • 본 연구는 간호학생의 급성 심근경색증 간호에 대한 시뮬레이션 기반 교육을 적용하고 비판적 사고, 문제해결력 및 학업성취도의 효과를 규명한 단일군 전후 원시실험설계이다. 대상자는 총 137명이었으며 중재기간은 2011년 9월부터 10월까지 총 6주간 시뮬레이션 기반 교육을 시행하고 중재 전후를 평가하였다. 자료분석은 SPSS Win17.0을 사용하였고, 평균과 표준편차, Paired t-test, 피어슨 상관계수를 이용하였다. 연구 결과 시뮬레이션 기반 교육프로그램은 비판적 사고, 문제해결력 및 학업성취도를 향상시키는 것으로 나타났다. 비판적사고가 증대될수록 문제해결력은 향상되는 것으로 나타났다. 반면 비판적사고 능력과 문제해결력은 학업성취도와 유의한 차이가 없었다. 시뮬레이션 기반 교육프로그램은 간호학생의 실무능력을 향상시키기 위해 유용한 학습방법임을 알 수 있었고, 임상현장에서 흔히 접할 수 있는 다양한 사례의 시나리오를 개발하여 실습교육에 적극 활용할 필요가 있다. 이를 위해서는 더 다양하고 적절한 실습교육방법에 대한 개발과 운영이 필요할 것으로 보인다.
