In this paper, tangram-like puzzles which are made by dissecting square are introduced. Especially, tangram-like puzzles which are consists of five pieces, six pieces, seven pieces, eight pieces, nine pieces, ten pieces, twelve pieces, fourteen pieces are introduced. But, This Introduction is very superficial. It means introduction is focused on each piece's geometrical shape, relative area when each tangram-like puzzles' area is one. With this introduction, six tangram-like puzzles' implication in mathematics education are suggested as followings. (1) Tangram-like puzzles may help fostering spatial senses. (2) Tangram-like puzzles may help teaching polygons, and its properties, congruences, similarities, etc. (3)Tangram-like puzzles may help teaching additions of fractions. (4) Tangram-like puzzles may help fostering mathematical thinking. (5) Tangram-like puzzles may serve as topics for supplement or reinforcement in teaching and learning tangram. (6) Tangram-like puzzles may serve as topics for problem posing in teaching and learning tangram.

퍼즐은 대중을 위한 놀이라는 인식에서부터 학습을 위한 도구로 활용하는데 관심이 증가하고 있다. 최근에는 수학퍼즐이 수학뿐만 아니라 정보교육에서도 창의성, 문제해결력, 긍정적 태도와 사고력 발달에 기여하는 것으로 밝혀지고 있다. 퍼즐이 가지는 대중성과 우수한 접근성에도 불구하고 퍼즐의 다양성 때문에 퍼즐 자체의 특성에 대한 연구가 부족하였다. 본 연구의 목적은 전문가가 수학퍼즐을 해결하는 과정에서 나타나는 수학적 사고를 확인하고 분석하여 수학퍼즐을 활용한 교수·학습에 도움을 주는데 있다. 분석 대상은 잘 알려진 20개의 수학퍼즐과 중·고등학생에게 인기 있는 수학퍼즐 단행본에 실린 85개의 수학퍼즐을 사용하였다. 분석 결과, 크게 논리-분석적 사고 기능과 창의적 사고 기능으로 분류되었으며, 논리-분석적 사고 기능은 순차적 연역 추리, 동시적인 조합적 사고, 단순화시킨 유추적 사고, 형식화하기, 수학 지식의 적용 등 5가지로 구분되었다. 그리고 그에 따른 문제의 특성과 해결에 요구되는 사고전략도 분석하였다.

이 연구에서는 진정한 '수학수업'의 맥락에서 수학퍼즐을 어떤 방법으로, 어떤 관점에서 제시할 것인지 논의하였다. 우선, 수학퍼즐의 일반적인 특징을 추출하고 수업 안팎에서의 다양한 활용을 조사하였다. 둘째로, 수학퍼즐을 의미 있게 전달하기 위한 수업방법을 논의하였다. 셋째로, 수학퍼즐을 어떠한 관점에서 다룰 것인지를 논의하였다. 마지막으로, 수학 퍼즐을 통한 수업은 학생들에게뿐 아니라 교사들에게도 '수학에 있어서의 여유'를 경험하게 해 준다는 점에 그 중요한 가치가 있음을 지적하였다.

In this study we tried to find the method of using the tangrams and the mosaic puzzles together for learning the elementary geometry in the Korean primary schools. The tangram and the mosaic puzzle activity-panels were developed and the activity-cards for them also were designed. The criteria to be used for the analyses of contents of the activity-cards were developed. We surveyed and analyzed the students' responses, A previous research had insisted that solely using the tangrams were not useful in learning about an obtuse-angled triangle in the elementary geometry (Welchman, 1999), but the combinative uses of the tangrams and the mosaic puzzles were found to extend the limits of the previous study in investigating the figures of the plain diagrams. Actually, the tangrams and the mosaic puzzles helped the students to learn the concepts of several elements of the plain diagrams such as 'angles', 'sides', and 'angular points', with students'operational comparison of the diagrams developed with them. They also provided useful clues in learning the relationship between the 'length' and the 'area' of the Plain diagrams. The students participated in the class with much activities, using the operational learning materials. They also comprehended the concepts and the principles of the elementary geometry more thoroughly, expressing their ideas in spoken or written languages through interactive communication. In conclusion, the tangram and mosaic puzzles can be used for learning the elementary geometry of the primary school level as motivative learning materials, helping students enhance diverse mathematical thinking and discover mathematical principles.

According to whether language symbols are used to solve puzzles, puzzle games can be roughly divided into puzzle games with language symbols and puzzle games without language symbols. Puzzles games with language symbols can be subdivided into dialogue puzzles games and word puzzles games. These different puzzle-solving methods have different characteristics and have different effects on the empathy in the game. In horizontal scrolling games, due to the characteristics of the third-person perspective of horizontal scrolling games, there is always a 'fourth wall' between the player and the controlled character, making it difficult for players to gain a empathy when playing such games .Especially when there is a dialogue between a player-controlled character and an NPC, the sense of distance between the player and the character will be further amplified. As one of the most common game types in side-scrolling games, side-scrolling puzzle games can be divided into language symbols-based puzzle game and non-language symbols-based puzzle game according to whether language symbols are used to solve puzzles, and then promote the development of the game plot. We combine the characteristics of horizontal scrolling games, and analyze the influence of language symbols on empathy in puzzle-solving games by summarizing the game characteristics of two different puzzle-solving methods. The results show that in horizontal scrolling puzzle games, solving puzzles without using language symbols can better expand the player's sense of plot substitution.

This paper aims to present solutions to three intriguing puzzles on causation that Benardete presents by considering the results of infinite series of telescoping events. The main conceptual tool used in the solutions is the notion of collective causation, what many events cause collectively. It is straightforward to apply the notion to resolve two of the three puzzles. It does not seem as straightforward to apply it to the other puzzle. After some preliminary clarifications of the situation that Benardete describes to present the puzzle, however, we can apply the notion to resolve it as well.

최근 수학교육에서 펜토미노와 같은 절단 퍼즐들을 학습에 많이 활용하고 있다. 그러나 이런 퍼즐들의 개발 배경과 수학적 활용 방법에 대한 연구 부족으로 수학적 개념 도입이나 문제해결을 위한 소재로서 다양하게 사용되고 있지 못한 실정이다. 이 논문은 펜토미노를 수학 학습에서 효과적으로 활용하기 위하여 펜토미노와 같은 절단 퍼즐의 배경이 되는 기하학적 문제와 펜토미노의 개발에 관한 수학사적 배경을 알아보고, 제 7차 초등학교 교육과정의 수학 교과서에서 활용할 수 있는 단원과 여러 문헌에서 펜토미노를 활동한 자료를 조사하여 체계적인 수학 학습자료를 개발하는 기초 자료와 방향을 제시하는 데 그 목적이 있다.

Puzzles of various types were made of wood. Children aged 3 to 5 were play directly into a wooden puzzle, then, mainly in adults, the survey was conducted. Comparisons of affinity for the children, teachers, parents, survey were compared with the rating. As a result, the preferred material of the puzzle was in the timber. The type of puzzle children, teachers and parents preferred picture puzzle. For colors, teachers and parents of the puzzle as unpainted wood was preferred. In addition, the favorite play was the difference in difficulty and number puzzles. Therefore, the preference for children and adults aware of the puzzle with a big difference has been clearly identified.
