  • One of the most important aims in mathematics education is to enhance students' problem-solving abilities. To achieve this aim, in real school classrooms, many educators have examined and developed effective teaching methods, learning strategies, and practical problem-solving techniques. Among those trials, it is noticeable that Engel, Zeits, Shapiro and other not a few mathematicians emphasized 'Invariance Principle' as a mean of solving problems. This study is to consider the basic concept of 'Invariance Principle', analyze 'Invariance' concept in secondary Mathematics contents on the basis of framework of 'Invariance Principle' shown by Shapiro and discuss some instructional issues to occur in the process of it.

  • This study investigated preschoolers' emotionality, emotional knowledge, event knowledge, and interpersonal problem solving strategies according to their sex and age, and the relationships among them. Subjects were 116 preschoolers (73 boys and 43 girls; 68 four- and 48 five-year-olds). Results showed that girls were higher in negative emotionality (sadness) than boys. Also, 5-year-old children were higher in emotional knowledge, event knowledge, and forceful problem solving strategies than 4-year-olds. Furthermore, children's event knowledge was positively related to their relevant problem solving strategies, while children's event knowledge was negatively related to their forceful problem solving strategies. These findings provide a preliminary evidence that children's event knowledge may predict their interpersonal problem solving strategies.

  • STEAM education is a topic-based curriculum to integrate the concepts into other subjects such as science, technology, engineering, art and mathematics in order to improve the students' interesting, understanding, integrated thinking and problem solving ability. In this paper, we designed STEAM curriculum in the form of Project-based Learning and developed the material for elementary students. We also developed the android-based application through searching for a utilization of IT simulation for enhancement the students' Project-based Learning effect.

  • The subjects of this comparison of institutionalized and home-reared preschool children's emotional knowledge and interpersonal problem solving strategies were 38 institutionalized (23 boys and 15 girls) and 39 home-reared (15 boys and 24 girls) preschool children. Assessment of emotional knowledge consisted of identification tasks and situation tasks. Interpersonal problem solving included forceful, prosocial, and manipulative strategies. Results showed that institutionalized children were lower than home-reared children in emotional knowledge; that is, they had lower scores than home-reared children in situation task. Institutionalized children used more forceful strategies than home-reared children, and home-reared children used more prosocial strategies than institutionalized children. Emotional knowledge was positively related to their prosocial strategies and negatively related to forceful strategies.

  • In this study, the effects of grouping by extraversion and introversion in paired think-aloud problem solving using a four-stage problem-solving strategy emphasizing planning and checking stages were investigated. Prior to the instructions, the students' extraversion/introversion in three high school classes (N=87) were examined, and those classes were randomly assigned to the homogeneous, the heterogeneous, and the control groups. The test scores of the two treatment groups were significantly higher than those of the control group in the problem-solving ability. However, there were no significant differences in learning difficulty and self-efficacy. Although there were no significant differences between the scores of two treatment groups in the subcategories of the perception of treatment, the test scores of extroverts were significantly higher than those of introverts in the perception of performing listener's role, the preference to problem solving strategy, and the preference to paired think-aloud problem solving.

  • The purpose of this study is to investigate the correlations between technological problem solving strategies and variables related with self-regulation of students in engineering college. The subjects for this study are 120 students from engineering college. After using the problem solving strategy task and self-regulation questionnaire, they were classified into two groups, upper 25% group and bottom 25% group. The data was analyzed using the SPSS 10.0 for windows. The statistical technique used for data analysis was Pearson's correlation coefficient and t-test. The major conclusions of this study are as follows. Frist, there is positive correlation between strategies of design and self-efficacy & planning. Second, there is positive correlation between strategies of trouble shooting and self-monitoring, planning and effort. Third, especially self-efficacy, one of the self-regulation subvariables, directly affects on technological problem solving strategies.

  • The purpose of this study was to analyze the problem solving strategies of ordinary students, gifted students, pre-service teachers, and in-service teachers with the 'chicken and pig problem,' which has multiple strategies to obtain the solution. For this study, 98 students in the 6th grade elementary schools, 96 gifted students in a gifted institution, 72 pre-service teachers, and 60 in-service teachers were selected. The researcher presented the "chicken and pig" problem and requested them the solution strategies as many as possible for 30 minutes in a free atmosphere. As a result of the study, the gifted students used relatively various and efficient strategies compared to the ordinary students, and there was a difference in the most used strategies among the groups. In addition, the percentage of respondents who suggested four or more strategies was 1% for the ordinary students, 54% for the gifted students, 42% for the pre-service teachers, and 43% for the in-service teachers. As suggestions, the researcher asserted that various kinds of high-quality mathematical problems and solving experiences should be provided to students and teachers and have students develop multi-strategy problems. As a follow-up study, the researcher suggested that multi-strategy mathematical problems should be applied to classroom teaching in a collaborative learning environment and reflected them in teacher training program.

  • Developing middle and high students' information literacy and creative problem-solving skills in this information-oriented society is very important and for this reason, the subject of informatics has been established. However, little research on creative problem solving literacy of informatics textbooks has been conducted. Therefore, the purpose of this paper is to quantitatively analyze whether 'problem-solving methods and procedures' parts in informatics textbooks in middle schools present creative problem solving literacy or not and in what degree. Data were quantitatively analyzed using the Gil-Su Choi method. The result of data analysis indicated that all the textbooks turned out to be correct range in the category of the "composition of various learning activities," but got out of range in some categories such as "problem-solving process reflection" and "problem-solving strategy proposal". Also a few textbooks haven't satisfied in important indexes and activities. So, we suggest that more 'problem-solving process reflection' and 'problem-solving strategy proposal' parts should be included in the informatics textbook and more various forms of learning activities be utilized well as the ratio of activities needed primary and high mental processes be kept the balance.
