  • The purpose of this study is to extract empathy factor in scientists' problem-solving process and to examine how the empathy factor influences scientists' problem-solving situation. In this study, we selected six common persons among the scientists mentioned by creativity researchers. And through their autobiographies and biographies, we extracted elements of empathy from their case of problem-solving and categorized them. We analyzed cases from 12 books and 50 papers using Davis' empathy scale as an analysis framework and extracted common factors. As a result, the scientific empathy elements were extracted from a total of 182 cases, and 33 common elements were found. The validity of this case was verified through the content validity test of the science education specialist group. As a result, the I-CVI average was .86 and the S-CVI average was .90. For the empathy elements that scientists used in problem-solving cases, in cognitive empathy, three elements (empathy through other disciplines, empathy from the perspective of the research object, accommodating others' opinions) were extracted in terms of perspective-taking, and three elements (imagination thought experiment based on observation, thought experiment, feeling like part of object) in fantasy. And in affective empathy, three elements (influenced by fellow researchers' motivation, touching from the subject, excitement studying more) were extracted in terms of empathic concern and two elements (heartache for others' failure in their research, sensitivity to problems) in personal depression. This could not be said to be a perfect match for Davis' empathy, but it would be possible to define the scientific empathy elements based on these common elements found in the scientists' cases.

  • Computer programming education gives students a chance to use computers independently and actively. This plays a very positive role in acquiring higher cognitive skills such as mathematical skills and creative logical thinking. Thus the purpose of this study is to measure the degrees of students' problem-solving abilities using MCU programming kits based on the ICT Education Guide. The experiment confirms that programming classes using MCU kits have a more positive effect on the students problem-solving abilities than do those using the existing computer textbooks. The sub-constituents of problem-solving abilities - problem recognition, information gathering, analysis, diffuse thinking, decision-making, planning, execution, evaluation and feedback - also show significant statistical differences. Therefore, we can conclude that programming classes using MCU kits are very effective in advancing problem-solving abilities.

  • The purpose of this study is to examine the effect of cooperative making problems and solving problems for formative assessment at finish stage on science academic achievement and scientific attitude. This study is conducted in 51 sixth-graders of two classes. The experimental group was provided with a teaching-learning course based on cooperative making problem and solving problem at finish stage. And the control group was provided with general classes based on the contents in teacher's guidebooks. The experiment was performed with the second and third units of the sixth grade, for about two month and obtained the following results: First, students prefer to make supply-type items than multiple choices. And by the Bloom's revised taxonomy of educational objectives, students prefer to make the problem types of 'Factual Knowledge' and 'Conceptual Knowledge'. Also students prefer to make the problem types of 'Understanding' and 'Applying'. Second, cooperative problem making and solving problems at finish stage has same effect on academic achievement in comparison to teacher-driven activity. Third, the experimental group made statistically significant difference in self-efficiency, contrary to the general science classes. Especially, it turned out that a meaningful effect was discovered to a cooperativity, openness. Finally, it turned out that many students thought cooperative making problem and solving problem at finish stage gave the help approving their cooperativity and openness at the investigation of awareness.

  • The purpose of this study was to develop and apply a creative problem-solving(CPS) program of instruction for earth science. After the earth science sections of high school science textbooks were analyzed, a theme of instruction was selected from the first-year unit 'the origin and evolution of the universe', and a CPS model of instruction. 32 high school sophomores and juniors who were the members of an astronomy club in the city of Gimhae, South Gyeongsang Province, participated in the program, and they took a test in scientific creative problem-solving skills before and after the experiment to grasp the effect of the program on their creative problem-solving skills. Besides, a survey was conducted to find out their awareness of the program. As a result of implementing the CPS program based on the CPS model of instructional for the unit 'the origin and evolution of the universe', the program turned out effective at boosting the scientific creative problem-solving skills of the students. To be specific, they made a significant progress in validity and scientificity, but that's not the case for elaboration and originality. When their awareness of the CPS program was checked, they expected the program to spark their interest in astronomy and be beneficial to the improvement of their creative problem-solving skills, but they didn't rate group activities high on the ground that the group activities weren't performed smoothly. The findings of the study suggest that the CPS instructional program for the unit 'the origin and evolution of the universe' based on the CPS model of instruction had a good effect on the improvement of the scientific creative problem-solving skills of the students.

  • The purpose of this research is to find out effectiveness of geometry learning through spatial reasoning activities on mathematical problem solving ability and mathematical attitude. In order to proof this research problem, the controlled experiment was done on two groups of 6th graders in N elementary school; one group went through the geometry learning style through spatial reasoning activities, and the other group went through the general geometry learning style. As a result, the experimental group and the comparing group on mathematical problem solving ability have statistically meaningful difference. However, the experimental group and the comparing group have not statistically meaningful difference on mathematical attitude. But the mathematical attitude in the experimental group has improved clearly after all the process of experiment. With these results we came up with this conclusion. First, the geometry learning through spatial reasoning activities enhances the ability of analyzing, spatial sensibility and logical ability, which is effective in increasing the mathematical problem solving ability. Second, the geometry learning through spatial reasoning activities enhances confidence in problem solving and an interest in mathematics, which has a positive influence on the mathematical attitude.

  • In creative design, it is necessary to understand the characteristic of architectural design. In the world of design problem, a distinction can be made between those that are well-defined and those that are ill-defined. Well-defined problems are those for which the ends or goal, are already prescribed and apparent, their solution requires the provision of appropriate means. For ill-defined problems, on the other hand, both the ends and the means of solution are unknown at the outset of the problem solving exercise, at least in their entirety. Most of design problems is ill-defined, which is unknown at the beginning of the problem solving exercise. In order to solve the design problem, Designers take advantage of the search methods of problem space, such as global-search-methods(depth-first-methods, breath-first-methods), local-search-methods(generate and test, heuristics, hill-climbing, reasoning) and visual thinking, which is represented through sketching. Sketching is a real part of design reasoning and it does so through a special kind of visual imagery. Also in the design problem solving it have been an important means of problem exploration and solution generation. By sketching, they represent images held in the mind as well as makes graphic images which help generate mental images of entity that is being designed. The search methods of problem space and a visual thinking have been crucially considered in the architectural design. The purpose of this paper is to explore the property of design by means of the pre-existed-experiment data and literature research. The findings will help design the architectural design for more creative results.
