Despite the popularity and convenient accessibility of puzzles, the variety of puzzles have led to a lack of research on the nature of the puzzle itself. In guiding certain skills, such as abstractness, creativity, and logic, a teacher should have the thinking skill and strategy that appear in solving puzzles. In this study, the mathematical thinking that appears in solving puzzles from the perspective of experts is identified, and the strategies and characteristics are described and classified accordingly. For this purpose, we analyzed 85 math puzzles including the well-know puzzles to the public, plus puzzles from a popular book for the gifted student. The research analysis shows that there are 6 types of mathematics puzzles in which require mathematical thinking.

The purpose of this study is to investigate the effect of science classes using elementary school distance science classes on science academic achievement and creative personality. The research group and non-research group were selected for 6th grade elementary school students. After 10 weeks of experimental treatment, science classes were conducted with the contents of the elementary school science section, 'Changes of the seasons'. In the three domains of 'knowledge', 'inquiry', and 'attitude', which are sub-domains of science academic achievement, as a result of the pre-post test, there was a positive effect in 'inquiry' and 'attitude', which are sub-domains of science academic achievement. However, it was found that there was no positive effect in 'knowledge', a sub-domain of academic achievement. However, it was found that there was a positive effect in the overall test result of academic achievement. Therefore, it is interpreted that science classes using elementary school distance science classes had an effect on academic achievement. There was a significant effect in the sub-domains of the creative personality test, 'persistence/obsession', 'self-confidence', 'humor', 'imagination', 'openness', 'adventure', and 'independence'. However, it was found that there was no effect in the sub-domain 'curiosity'. The overall test results of the creative personality test showed a significant effect. Therefore, it is interpreted that science classes using elementary school distance science classes are effective in cultivating creative personality. Students' perceptions of science classes using elementary school distance science classes also showed positive responses.

We consider a Direct Input Output Manufacturing System(DIOMS) which has a munber of machine centers placed along a built-in Automated Storage/Retrieval System(AS/RS). The Storage/Retrieval (S/R) machine handles parts placed on pallets for the operational aspect of DIOMS and determines the optimal operating policy by combining computer simulation and genetic algorithm. The operational problem includes: input sequencing control, dispatching rule of the S/R machine, machine center-based part type selection rule, and storage assignment policy. For each operating policy, several different policies are considered based on the known research results. In this paper, using the computer simulation and genetic algorithm we suggest a method which gives the optimal configuration of operating policies within reasonable computation time.

Despite the necessity and significance of mathematical competencies in the 2015 revised mathematics curriculum, there has been lack of studies analyzing textbooks in which such competencies are intended in detail through various tasks. Given this background, this paper analyzed how mathematical competencies and their sub-elements have been represented in the mathematics textbooks for third and fourth grade. The findings of this study showed that 'communication' was the most prevalent mathematical competence, followed by 'reasoning', 'creativity and integration', 'information processing', 'attitude and practice', and 'problem solving' in order. This study also explored the characteristics of mathematical competencies in the textbooks by analyzing which sub-elements per competence were popular. With illustrative examples, this paper is expected to provide for textbook developers with implications on how to represent mathematical competencies throughout the textbooks.
