The main purpose of STEM education is to understand methods of inquiry in each discipline to develop convergent problem solving skills. To do this, we must first understand the problem-solving process that is regarded as an essential component of each discipline. The purposes of this study is to understand the relationship between the problem solving in science (S), engineering (E), mathematics (M), and computational thinking (CT) based on the comparative analysis of problem solving processes in each SEM discipline. To do so, first, the problem solving process of each SEM and CT discipline is compared and analyzed, and their commonalities and differences are described. Next, we divided the CT into the instrumental and thinking skill aspects and describe how CT's problem solving process differs from SEM's. Finally we suggest a model to explain the relationship between SEM and CT problem solving process. This study shows how SEM and CT can be converged as a problem solving process.

The purpose of the research is to offering an implication about problem posing instruction for improving problem solving ability through 5th grade elementary school students' responses on problem posing. For the purpose a survey was implemented to 281 students at Busan urban area. There was a difference between the students' completeness in terms of problem posing types. They tended to make more simple problems linguistically rather than complicated problems and made problems for the equation easily. At first for the problem posing, students need to be taught to learn for making appropriate problems about an equation.

Collaboration and assistance among peer learners are essential factors for successful learning outcomes. However it is important to investigate students' preferences for computer problem solving methods and interrelationships, since students tend to solve problems more and more by themselves. This is because of the importance of giving appropriate instructions to students. In this context, this paper shows the analysis of the preferred methods and interrelationships of studnets' preferences upon encountering difficulties during computer usage by collecting data from 231 students in K national university of education. As a result, the result shows that students tend to solve problems without asking as they have higher abilities in computer usage, which was also shown to increase along with their grade levels. Furthermore, it showed that students who have family members and relatives, and who are using the internet are more satisfied with their problem solving. Lastly, it is possible to grasp the computer problem solving network within the department by using social network analysis, so it can be used as reference data for selecting the peer learners, which will help to operate the customized computer education practice.

The purpose of this study was to determine the effects of simulation practice education applying problem-based learning on problem-solving ability, critical thinking disposition, and learning satisfaction of nursing students. 63 nursing students taking the practice subject for integrated simulation at U University in K region were asked to complete a self-administered questionnaire to collect data before and after the simulation practice. The simulation practice education applying problem-based learning was effective in improving problem-solving ability and learning satisfaction significantly and positive correlation was found among problem-solving ability, critical thinking disposition, and learning satisfaction; that is, the better problem-solving ability, the higher level of critical thinking disposition and learning satisfaction. While the results of this study conducted in nursing students at a single university cannot be generalized, it was confirmed that simulation practice education applying problem-based learning was an effective teaching method in improving problem-solving ability and learning satisfaction of nursing students. It is therefore necessary to give simulation practice education applying problem-based learning on a systematic and continuous basis with the objective of improving problem-solving ability and learning satisfaction and promoting critical thinking disposition.

Mobility data is important to understand social phenomena and problem. Previous studies have utilized Origin-Destination (OD) visualization methods to represent human's mobility. However, the effectiveness of visualization tools as a method for understanding social phenomena remains unexplored. Therefore, in this study, we developed a visualization tool called SeoulOD-Vis to facilitate understanding social issues. It included three different modules: map visualization, condition selection, and detailed information presentation. We recruited 28 participants to evaluate the SeoulOD-Vis and compared it with a publicly available visualization tool. The results suggested that the SeoulOD-Vis had higher usability and problem-solving performances. Interview results suggested that it attributed to its 'condition selection' and 'detailed information presentation' modules. Our results will contribute to develop visualization tools to solve social problems using mobility data.

Traditionally engineers' main roles are concentrated on solving any given problems and engineering education has emphasized problem solving ability. Therefore engineers intend to solve easily perceived problems with their knowledge and experience instead of trying to analyze the given problems thoroughly and to define real problems, and go through lots of trial and error. So, engineers require the ability to define real problems accurately before trying to solve the problems. This study proposes a real problem definition process using visualization of a core zone and TRIZ concepts such as contradictions and IFR(Ideal Final Result) in order to define real problems with minimum trial and error. TRIZ is the theory of inventive problem solving and was developed by a Soviet engineer and researcher Genrich Altshuller from 1946. Nowadays many industries use TRIZ and its effectiveness was already proved by lots of real problem solving in various areas. Therefore TRIZ might be very effective tool for developing students' inventive thinking ability in engineering education.
