  • 영재들은 그들의 특성상 지적인 호기심과 높은 과제집착력을 갖고 있다. 물론 그들이 갖고 있는 능력으로 봤을 때 알고리즘 수업을 진행하면 어느 정도의 문제해결력을 신장시킬 수 있다. 본 연구에서는 정보영재들의 능력을 조금 더 끌어올리는 것에 연구에 목적을 두고 있으며 동기유발전략을 활용하면 기존의 알고리즘 수업보다 더 높은 문제해결력을 키우는 것에 가설을 두고 연구를 진행하였다. 알고리즘 수업은 기존 정보교육과정과 비교하여 비슷한 수준으로 구성하였으며 실생활과 관련된 수업 모형을 연구, 적용한 후 문제해결능력 검사지[4]를 이용하여 그 효과를 검증하였다. 검사 결과 실험집단의 문제해결능력이 통제 집단에 비해 향상된 것으로 나타났다. 이러한 결과는 전통적인 알고리즘 수업보다는 정보영재들의 지적인 호기심과 자신감을 자극한 수업이 학습자의 문제해결능력을 향상시켰음을 의미한다. 이는 같은 내용이라도 동기유발전략을 활용한 수업이 효과적이라는 것을 확인할 수 있었고 앞으로도 다양한 전략을 활용한 수업이 필요함을 기대한다.

  • This study aims to elucidate the relationship between the characteristics of adult learners and flow in cyber-class along with relationships among flow, stress, and problem-solving ability. The research subjects were 1044 enrolled students at Cyber University located in Seoul through voluntary on-line questionnaire. The analysis is following: The components of flow on cyber-class including enjoyment, engagement, focused attention, and time-distortion show the significant difference upon the characteristics of adult learners such as school grade, age, marital status, and number of registered classes. In addition, the flow on cyber-class has the negative relationship with stress and the positive relationship with problem-solving ability. To improve the level of flow on cyber-class, it is important to develop the new on-line class and class materials with the consideration of characteristics and diverse backgrounds of adult learners. The incorporation of various interactive evaluation can also improve the flow level of adult learners in cyber class. Finally, the learning counselling service might be essential for adult learners to experience flow on cyber-class.

  • In this study, we investigated the methods of using the Cabri3D program for education of problem solving in school mathematics. Cabri3D is the program that can represent 3-dimensional figures and explore these in dynamic method. By using this program, we can see mathematical relations in space or mathematical properties in 3-dimensional figures vidually. We conducted classroom activity exploring Cabri3D with 15 pre-service leachers in 2006. In this process, we collected practical examples that can assist four stages of problem solving. Through the analysis of these examples, we concluded that Cabri3D is useful instrument to enhance problem solving ability and suggested it's educational usage as follows. In the stage of understanding the problem, it can be used to serve visual understanding and intuitive belief on the meaning of the problem, mathematical relations or properties in 3-dimensional figures. In the stage of devising a plan, it can be used to extend students's 2-dimensional thinking to 3-dimensional thinking by analogy. In the stage of carrying out the plan, it can be used to help the process to lead deductive thinking. In the stage of looking back at the work, it can be used to assist the process applying present work's result or method to another problem, checking the work, new problem posing.

  • Although fairly descent amount of research outcomes has been generated on problem-based learning(PBL) with regard to science and medical subjects, relatively less outcome has been generated on social science and management subjects. Therefore this study attempts to exam effect of problem-based learning in food service entrepreneurship subject on improving problem solving skills. After literature review, for constructing for this research frame, each class schedules were formed by hybrid-PEL and traditional lecture style respectively then problems, solution, and evaluation process were generated for hybrid-PBL. Through the result, there was hardly any differences occurred before and after traditional lecture approach on students' problem solving skills. There was, however, certain differences appeared on students' skills after hybrid-PBL approach. Through the study, hybrid-PBL learning can be an effective teaching method in social science and management subject for improving students' problem solving skill.

  • The purpose of the study is to analyze the 4th graders' visual representation in mathematics problem solving process and to find out how to teach the visual representation in mathematics problem solving process. on the basis of the results, this study gives several pedagogical implication related to the mathematics problem solving. The following were the conclusions drawn from the results obtained in this study. First, The achievement level of students and using visual representation in the mathematics problem solving are closely connected. High achieving students used visual representation in the mathematics problem solving process more frequently. Second, high achieving students realize the usefulness of visual representation in the mathematics problem solving process and use visual representation to solve mathematical problem. But low achieving students have no conception that visual representation is one of the method to solve mathematical problem. Third, students tend to especially focus on 'setting up an equation' when they solve a mathematical problem. Because they mostly experienced mathematical problems presented by the type of 'word problem-equation-answer'. Fourth even through students tried visual representation to solve a mathematical problem, they could not solve the problem successfully in numerous instances. Because students who face a difficulty in solving a problem try to construct perfect drawing immediately. But generating visual representation 2)to represent mathematical problem cannot be constructed at one swoop.

  • We present a link that allows Excel to call the functions in the lp_solve system. lp_solve is free software licensed under the GPL that solves linear and mixed integer linear programs of moderate size. Our link manages the interface between Excel and lp_solve. Excel has a built-in add-in named Solver that is capable of solving mixed integer programs, but only with fewer than 200 variables. This link allows Excel users to handle substantially larger problems at no extra cost. Futhermore, we introduce that a network drawing method in Excel using arc adjacency lists of a network.

  • This study was conducted to identify the level of problem-solving ability, critical thinking and satisfaction level of students majoring in dental hygiene, and to identify the impact of problem-solving ability and critical thinking on major satisfaction levels. The research target collected data through a structured questionnaire for 259 students majoring in dental hygienics located in North and South Gyeongsang Province. The analysis results showed that the problem-solving ability of the study subjects was 2.56, critical accidents were 2.58, and the major satisfaction level was 2.32, and the problem-solving ability, critical thinking and major satisfaction level were positively correlated with each other. Among the lower factors of problem solving ability, solution performance and solution model were significant factors that could improve major satisfaction, and among the lower factors of critical thinking, intellectual fairness, intellectual passion/interest, and systematicness were significant factors that could improve major satisfaction. Critical thinking also significantly mediated problem solving ability and major satisfaction level (β=).2602, BCCI [.0908~.4529]). Based on the results, it is believed that dental hygiene education needs to be developed in addition to the establishment of an educational environment that can enhance the ability to solve problems and critical thinking, and that research should be continued to check its effects.

  • This study was conducted to investigate the factors affecting the social anxiety in nursing students. A total of 227 nursing students participated in the study. Data were analyzed by frequencies, t-test, ANOVA, Pearson correlation coefficient, and multiple stepwise regression with SPSS WIN 18.0. The mean scores for problem solving ability and social anxiety were at the intermediate level. Problem solving ability negatively correlated with social anxiety. The significant predictors of social anxiety included cognitive reaction within the seven problem solving ability subscales and perceived interpersonal relationship. The regression model explained 22.6% of social anxiety. As a result, to decrease social anxiety in nursing students, nursing educators should develop educational intervention programs to change cognitive distortions presented in unfamiliar social situations and improve interpersonal relationships ability.
