Obiectives : The purpose of this study was to develop PBL packages geared toward improving the problem-solving abilities, self-directed learning capabilities and communicative competency of dental hygienists, which were all required for dental hygienists to have in the dental field. Methods : After three PBL packages for a semester of oral health education were developed, the PBL packages were evaluated by an expert to determine what improvements should be made. Results : The findings of the study were as follows. The three PBL packages were based on real clinical situations and designed to have a different degree of difficulty and provide problems in the form of scenario for learners to solve in a self-directed manner. When the packages were assessed by an expert, the packages were expected to make a contribution to the improvement of the three different abilities on which this study focused, and the packages were found to be appropriate in general in terms of learning content and field applicability, though they needed some modifications. Thus, this study attempted to develop PBL packages and let an expert assess the packages in order to give some suggestions about the development of PBL packages. The packages developed in this study are expected to help boost the problem-solving abilities, self-directed learning capabilities and communicative competency of dental hygienists, which should all be possessed by dental hygienists in the dental field. Moreover, the packages were found to be conducive to the introduction of PBL in the field of dental hygiene. Conclusions : To ensure the successful application of the packages, dental hygiene students should be provided with the packages in situations similar to real clinical situations, and they should have an opportunity to practice dental hygiene duties.

In this paper, we developed a design thinking-based artificial intelligence education program for middle school students and applied it to verify the impact on creative problem-solving skills. The inspection tool used the Creative Problem Solving Profile Inventory (CPSPI), an inspection tool for measuring creative thinking type ability based on the CPS theory of Hwasun Lee, Jungmin Pyo, Insoo Choe(2014). CPSPI included the steps of evaluating cognitive preferences and cognitive abilities by supplementing the limitations of existing tests, and sharing and persuading one's ideas with others. Before and after applying the design thinking-based artificial intelligence education program, as a result of analyzing the creative problem-solving ability, it increased significantly in all areas. As a result of analyzing the creative problem-solving ability of middle school students, significant results were found in the areas of Problem Detection and Analysis, Idea Generation, Action plan, Execution, Persuasion and Communication. The effect of design thinking was confirmed as a teaching and learning method to improve creative problem-solving ability in artificial intelligence education.

A camp program where the theory of inventive problem solving TRIZ is applied to real problems of the industry was developed and taught at a five-day seminar apart from the standard curriculum at a university D in Gyeonggido. This study focuses on the educational effect that the TRIZ method has on the engineering students when their creative problem solving skills are required to solve industry problems on their own with the knowledge from their courses. For five days, the students were educated about TRIZ and assigned a real industry problem "Removal of friction caused by bubble formation in water heating pipelines". By applying TRIZ to the problem, the students developed an "Air removing Air Arrester" which received the evaluation, "with understanding the system architecture and the task objective causes and formation of the problem could be handled which directly helps the company's R&D". In this case, TRIZ offers the students a guideline and knowledge on how to approach problems and as a result the students provided a practical solution. During the process, the TRIZ method instilled confidence in the students and proved to be a motivation. It becomes obvious that this short-term program has a positive effect on students' way of thinking creatively and increasing their problem-solving abilities.

Ill-structured problems have drawn attention in that they can enhance problem-solving skills, which are essential in future societies. The purpose of this study is to analyze and evaluate students' spatial reasoning(Intrinsic-Static, Intrinsic-Dynamic, Extrinsic-Static, and Extrinsic-Dynamic reasoning) and problem solving abilities(understanding problems and exploring strategies, executing plans and reflecting, collaborative problem-solving, mathematical modeling) that appear in ill-structured problem-solving. To solve the research questions, two ill-structured problems based on the geometry domain were created and 11 lessons were given. The results are as follows. First, spatial reasoning ability of sixth-graders was mainly distributed at the mid-upper level. Students solved the extrinsic reasoning activities more easily than the intrinsic reasoning activities. Also, more analytical and higher level of spatial reasoning are shown when students applied functions of other mathematical domains, such as computation and measurement. This shows that geometric learning with high connectivity is valuable. Second, the 'problem-solving ability' was mainly distributed at the median level. A number of errors were found in the strategy exploration and the reflection processes. Also, students exchanged there opinion well, but the decision making was not. There were differences in participation and quality of interaction depending on the face-to-face and web-based environment. Furthermore, mathematical modeling element was generally performed successfully.

This paper propose to use a new educational programming language, Scratch, to help students' programming study. For this purpose, a course has been developed which consists of (1) strategies to motivate students and (2) Creative Problem Solving (CPS) teaching model to improve their problem solving abilities. We experimented the course with sixth-grade elementary students for 4 weeks and we could observe that the Scratch programming learning helps motivating students and improving their problem solving abilities. Based on this observation, we believe that Scratch programming can be an alternative for current programming education in elementary schools.

The purpose of this study is to examine the effects of mathematical modeling activities on mathematical problem solving abilities and mathematical dispositions in elementary school students. For this study, we administered mathematical modeling activities to fifth graders, which consisted of 8 topics taught over 16 classes. In the results of this study, mathematical modeling activities were statistically proven to be more effective in improving mathematical problem solving abilities and mathematical dispositions compared to traditional textbook-centered lessons. Also, it was found that mathematical modeling activities promoted student's mathematical thinking such as communication, reasoning, reflective thinking and critical thinking. It is a way to raise the formation of desirable mathematical dispositions by actively participating in modeling activities. It is proved that mathematical modeling activities quantitatively and qualitatively affect elementary school students's mathematical learning. Therefore, Educators may recognize the applicability of mathematical modeling on elementary school, and consider changing elementary teaching-learning methods and environment.
