  • The purpose of this study is to analyze the characteristics of efficient problem-solving teams and inefficient problem-solving teams using SYMLOG. In this study, 35 college students majoring in engineering education at C university were organized into 7 teams and carried out technological problem solving projects over one semester. Based on the results of the team project, the top 2 teams were defined as efficient problem solving teams and the bottom 2 teams were defined as inefficient problem solving team, and analyzed the characteristics of the team using SYMLOG. The main results are as follows: First, an analysis of SYMLOG from efficient problem solving teams and inefficient problem solving teams showed that there was a difference between self-awareness and others' perception in terms of U(Upward)-D(Downward) dimension. Second, in the inefficient problem solving teams, there was a significant difference between self-awareness and others' in the F(Forward)-B(Backward) dimension. Third, there was no difference between self-awareness and others' in both efficient and inefficient teams at the P (Positive)-N(Negative) dimension. Fourth, an efficient problem-solving team had a clear leader, and there was a team member who supported the leader. On the other hand, the inefficient problem-solving team did not have a clear leader, or one person played the role of leader and there were no team members supporting the leader.

  • Purpose: The aim of this study was to determine the predictive strength of students' self-efficacy, problem-solving skills, and other characteristics in performing intravenous practices and monitor phlebitis and infiltration. Methods: This cross-sectional study was carried out with 736 third and fourth-year students studying at the Health Sciences Faculties of Balikesir and Sakarya universities. The data were collected using the Self-Efficacy Scale, Problem-Solving Inventory and Catheter Care and Infiltration Monitoring Questionnaire. Results: The participants' mean Catheter Care and Infiltration Monitoring Questionnaire score significantly and positively correlated with their mean Self-Efficacy Scale score on a moderate level (r=.25; p<.001) but significantly and negatively correlated with their mean Problem-Solving Inventory score on a moderate level (r=-.21; p<.001). In other words, because a low Problem-Solving Inventory score indicates that the person's problem-solving skill is high, the Care and Infiltration Monitoring Questionnaire score increased as the problem-solving skill increased. While the Self-Efficacy Scale predicted the year of study and catheter care and infiltration monitoring variables positively, the Problem-Solving Inventory predicted the satisfaction with the profession variable negatively. Conclusion: Self-efficacy, problem-solving, liking the profession, and year of study predict success in catheter care and infiltration monitoring. For this reason, guidance may be provided in the development of a comprehensive education system toward increasing students' problem-solving skills, self-efficacy, and professional knowledge and skills.

  • The purpose of this research was to investigate the effect of using digital science textbook on the scientific problem solving of elementary school students. For this research, an instrument to measure student's problem-solving skills was developed. The pretest and posttest scores of one hundred and six 5th grade students' problem-solving skills were analyzed and also the responses of three students who were selected by their levels in the problem-solving science digital textbook class were qualitatively analyzed. The results of this study were as follows; the scores of problem solving skills of science digital textbook groups were higher than that of traditional paper textbook group(p<.05). In the qualitative analysis of the students' reponses in a digital textbook class according to their achievement level, low-achievers' problem-solving skills were much more improved than high- and mid-achievers' skills. In conclusion, science digital textbook has a potential to improve students' scientific problem solving skills, and this possibility will be much higher when science digital textbook is used with teachers' intended instructional goals and strategies like problem-solving lessons.

  • The purpose of the study is to investigate the effects of problem solving models and middle school students' recognition inproblem solving activities and to get implications of problem solving activities in science education. We took the position of problem solving as consisting of four sequential stages: search of problems, performance of the plan, presentation of results, and evaluation of the presentation. Taking into account thechosen activity factors for each stage of problem solving, we developed detailed activity tools that are supposed to guide the stage. Recognition of problem solving activities in 7th grade middle school students were positive. Students felt that problem solvingactivities made them engage more and interested in science classes, and that they were helpful in solving problems in everyday life. Even though they found real problems in everyday life, they preferred problem solving activities to deal with real problems rather than simple minded ones.

  • This study aims to identify the characteristics of gas phase problem solving of college freshmen. Four students were participated in this study and solved the problem by using think-aloud method. The thinking processes were recorded and transferred into protocols. Problem solving stage, the ratio spended in each solving stage, solving strategy, misconceptions, and errors were identified and discussed. The relationships between students' belief system about chemistry problem solving and problem solving characteristics were also investigated. The results were as follows: 1. Students felt that chemical equation problem was easier than word problem or pictorial problem. 2. When students had declarative knowledge and procedural knowledge required by given problem, their confidence level and formula selection were not changed by redundunt information in the problem. 3. When the problem seemed to be difficult, students tended to use the Means-End or Random strategy. 4. In complicated problems, students spent longer time for problem apprehension and planning. In familiar problems, students spent rather short time for planning. 5. Students spent more time for overall problem solving process in case of using Means-End or Random strategy than using Knowledge-Development strategy.
