Recently, the necessity and importance of entrepreneurship education in universities in terms of nurturing creative talents and career paths have been emphasized. This study attempted to examine the mechanism of how the effectiveness of entrepreneurship education affects career maturity by dividing it into theoretical education and practical entrepreneurship education with problem-solving competency rather than a single dimension. This study performed an empirical analysis using Smart PLS for 153 college students. The results of the analysis are as follows. First, it was found that theoretical and practical entrepreneurship education had a significant positive (+) effect on problem-solving ability. Second, theoretical entrepreneurship education had a positive (+) effect on career maturity. but practical entrepreneurship education did not have a direct significant effect on career maturity. Third, problem-solving ability had a positive (+) effect on career maturity. Finally, the mediating effect analysis revealed that problem-solving ability had mediating effects on both entrepreneurship education and career maturity of college students. In conclusion, this study has its significance in that it presents the effectiveness and direction of entrepreneurship education both in theory and practice at a time when it is urgent to foster inspiring and creative talent in universities to meet the demands of the times. In particular, it was analyzed that entrepreneurship education conducted at universities is required to upgrade the curriculum, content, methodology, and subject design of practical entrepreneurship education, and there is an urgent need for improvement so that the effect of practical entrepreneurship education can have a significant effect on career maturity.

The purpose of this study was to identify the problems faced by students in sub-microscopic representation of acid-base reactions. Herein, we selected 30 students of 12th grade science classes, who had studied various acid-base models. In order to investigate the sub-microscopic representation ability of the students, we developed nine items related to various contexts, such as one type of solute and solvent, two types of solutes and solvent, cases with water as solvent or with nonaqueous solvents. For all items, we consistently observed lack of concept of chemical change. In context of aqueous and nonaqueous solutions, the frequency of lack of concept of chemical bonding was high if ammonia was the solute or solvent. Moreover, the frequency of lack of concept related to the degree of electrolytic dissociation was high. Therefore, chemistry teachers should understand that students' ability to sub-microscopic representation of acid-base reactions can be enhanced by analyzing the difficulties faced by the students in solving diverse acid-base problems.

The purpose of this study was to determine the strategies that middle school students used in solving problems concerning density and solubility. These were compared in the aspects of problem contexts for 42 students of varying logical reasoning ability, spatial ability, and learning approach. A coding scheme used consists of five categories: reading & organization, production, errors, evaluation, and strategy. Students' protocols were analyzed after intercoder agreement had been established to be .95. The results were as follows: 1. Students had more difficulties in reading and organizing the problems in everyday contexts than in scientific contexts. Students at the concrete-operational stage and / or surface approach were more likely to have difficulties in reading and organizing the problems than those at the formal-operational stage and / or deep approach. 2. Students tended to split up the solubility problems into sub-problems and to solve the density problem in everyday contexts in random manner. These were significantly correlated with the test scores concerning logical reasoning ability, spatial ability, and learning approach at the .1 level of significance. 3. Major errors in solving the density problems were to disregard the given information or generated and to use inappropriate information. Many errors in solving the solubility problems were found to be executive errors. The strategy to use the information given appropriately was positively related to students' logical reasoning ability, spatial ability, and learning approach. 4. More evaluation strategies were found in everyday contexts. Their strategies to grasp the meaning of answers and to check the math were significantly related to students' logical reasoning ability. 5. Students used the random trial-and-error strategy more than the systematic strategy and the systematic trial-and-error strategy, especially in everyday contexts. The strategies used by the students were significantly related to students' logical reasoning ability, spatial ability, and learning approach.

To find out the effect of interest on chemical content, interest in chemistry, choice of science elective subjects, teaching-learning characteristics that make it difficult to understand contents, academic achievement in general chemistry according to university admission screening, etc. were surveyed on 51 students enrolled in the department of chemistry education at P college of education. As a result of the survey, it was found that the interest in Chemistry I, Chemistry II, and general chemistry increased significantly to 94.6%, 73.7%, and 66.0%, respectively. 39.3% of the students answered that they had a lot of difficulty in understanding general chemistry. The characteristics of learners who make it difficult to understand the content were found to be 'lack of willingness to learn' such as 'lack of understanding chemical concepts' and 'lack of problem solving', due to the lack of 'basic knowledge'. As a way to solve these difficulties, 'expert help' appeared the most. The grades of general chemistry of students who entered the regular admission were relatively higher than those of occasional recruitment.

This study investigated small group processes in paired think-aloud problem solving. Two high school chemistry classes were assigned to St-SL group (using Strategy-Solve Listener) and SL group (Solver Listener), and their small-group behaviors were audio/video taped. Verbal behaviors of solver and listener in respect to 4 problem-solving stages and performance levels at each stage were analyzed. At the understanding stage, listeners in the St-SL group exhibited more behaviors of agreement to solver's understanding processes about given and goal of problem. As regards recalling a related law at the planning stage, solvers in the St-SL group exhibited more behaviors of modification based on listener's questions or pointing out. These verbal interactions seemed to have a positive effect on students' deriving the physical quantity with the proper laws. Few in both SL and St-SL groups exhibited the behaviors regarding setting up subgoals. No verbal behavior was observed in the SL group at the reviewing stage, and solvers in the St-SL group tended to ask for listener's agreement. However, only few performed the strategy explaining the meaning of answer at the molecular level correctly through the interactions. The St-SL group perceived that the understanding stage was the most helpful and that the planning or reviewing stages were difficult to apply.
The purpose of this research was to analyze the impact of Collaborative Problem solving for Character competency (CoProC) applied science classes on the character competence and scientific affective characteristics of vocational high school students. To achieve this, two junior classes of chemical industry majors in a vocational high school, were selected as the experimental group with 43 participants, and character competence test, scientific affective characteristic test, group discussion voice recordings, reflection activity sheets were analyzed. Based on the results of the study, the experimental group showed a statistically significant differences in value for the total character competence test score compared to the control group, and it had statistically significant differences in the nine lower character competence factors. Based on the results of the scientific affective characteristic test result, the experimental group was higher in total score to a statistically significant degree compared to the control group, and showed a statistically significant difference in seven of the lower factors, excluding consistency in interest. Therefore, science classes with CoProC applied were effective in cultivating the character competence and enhancing the scientific affective characteristics of vocational high school students.
The purpose of this study was to investigate the effects of role assignment in a group on collaboration in a mid- dle school science class to which Collaborative Problem Solving for Character Competency (CoProC) model was applied. For this purpose, 4 classes in the second year of a middle school located in a small and medium-sized city were selected, two classes among these were assigned roles, and the other classes were not. The science class with 4 topics using CoProC model was carried out. As a result of the study, in middle school science class to which CoProC was applied, it was effective in increasing the collaboration. As a result of analyzing the discussion process using the analysis framework for collaboration developed in this study, the group without role assignment was statistically significantly higher than the group with role assignment in the total score and the four sub-factors, especially in 'partnership building' and 'consensus building' which is a high level of collaboration.

Maker movement is emerging as one of the key areas of the fourth industrial revolution in recent years. The maker movement is to create and share what users need using a variety of inexpensive production tools such as open source software and hardware, 3D printers and laser cutters. We think that the effect would be enhanced if design thinking is applied to elementary and middle school (K-12) class. The purpose of this study is to develop a design thinking-based maker education program and to apply it to classroom for clarify the effect on the creative problem solving ability of elementary school students. In order to verify the purpose of the research, students in the 5th-6th grades of elementary school were divided into a controlled group and an experimental group. The general lecture maker class was applied in the controlled group, and our developed design thinking-based maker class was simultaneously applied in the experimental group. The creative problem solving ability test was conducted before and after the test, and its effectiveness was verified using statistical t-test. In conclusion, this study suggests that design thinking-based maker education program has a positive effect on elementary school students' creative problem solving ability.
This study investigated the condition of chemistry teacher's student competency assessment based on the inquiry report. To this end, an inquiry report was collected for chemistry teachers who took the training at two universities that conducted the 2020 first-class chemistry teacher training. The science subject competencies presented in NAEA analysis framework was used to analyze what kind of competencies teachers assess students through inquiry reports. A total of 63 chemistry teachers submitted inquiry reports, which were analyzed by competency, sub-element of each competency, and detail element to analyze the actual situation. As a result of the study, most chemistry teachers reflected their 'scientific inquiry and problem-solving ability' in their evaluation through inquiry reports. 'Ability to understand and apply scientific principles', which is mainly evaluated through paper-based evaluation, was partially used as confirmation of prerequisite learning at the beginning of the inquiry and the weight of evaluating 'scientific communication skill' was not large. In 'scientific inquiry and problem-solving ability' through inquiry report, 'design and conduct explorations', 'data analysis and interpretation' and 'drawing conclusion and suggesting solution' were mainly assessed. However, 'discover and recognize problems' and 'development and use of model' were hardly assessed.

The purpose of this study is to develop the middle school science curriculum to enhance creative problem-solving abilities. The reconstructed curriculum consisted of three big components, that is, scientific knowledge, process skills, and creative thinking skills. Five themes have been selected to incorporate with four areas of the middle school science curriculum, namely, physics, chemistry, biology, earth science. The five themes are structure, change, interaction, energy, and stability. Based upon these five themes, the individual or separated scientific knowledges of learners can be put into the unified knowledges. The process skills were observing, measuring, classifying, communicating, inferring, predicting, variable differentiating controling, data gathering analysis, establishing hypotheses, experiment design, and experimenting. Creative thinking skills include divergent and critical thinking. The finally developed curriculum is presented in the form of matrix.
