by A.C. Clairaut is the first geometry textbook based on the historico-genetic principle against the logico-deduction method of Euclid's This paper aims to recognize Clairaut's historico-genetic principle by inquiring into this book and to search for its applications to school mathematics. For this purpose, we induce the following five characteristics that result from his principle and give some suggestions for school geometry in relation to these characteristics respectively : 1. The appearance of geometry is due to the necessity. 2. He approaches to the geometry through solving real-world problems.- the application of mathematics 3. He adopts natural methods for beginners.-the harmony of intuition and logic 4. He makes beginners to grasp the principles. 5. The activity principle is embodied. In addition, we analyze the two useful propositions that may prove these characteristics properly.

Concerning elementary school science subject electric circuit units, which are regarded as difficult by teachers and students, this study aims to use the knowledge state analysis method along with interviews to analyze the knowledge state and hierarchy of inquiry abilities. Before and after applying the electric circuit inquiry abilities module, the question items aimed at assessing the basic inquiry abilities and integrative inquiry abilities for electric circuits were presented to students, and their knowledge state was analyzed along with interviews. Through analysis of the knowledge structure and hierarchy of inquiry abilities about electric circuits, the way of thinking of teachers who taught inquiry abilities, and the way of thinking of students were found to be visually different from each other, and this is an important factor that should not be neglected in the process of teaching and learning about inquiry abilities and should be considered. In addition, the presentation of the knowledge state of and hierarchical relations between inquiry abilities factors can offer implications for guidance on students' learning about inquiry abilities.

As a reversible Jacket is having the compatibility of two sided wearing, the matrix that both the inside and the outside are compatible is called Jacket matrix, and the matrix is having both inside and outside by the processes of element-wise inverse and block-wise inverse. This concept had been completed by one of the authors Moon Ho Lee in 1989, and finally that resultant matrix has been christened as Jacket matrix, in 2000. This is the most generalized extension of the well known Hadamard matrices, which includes both orthogonal and non-orthogonal matrices. This matrix addresses many problems in information and communication theories. we investigate the properties of the Jacket matrix, i.e. determinants, eigenvalues, and kronecker product. These computations are very useful for signal processing and orthogonal codes design. In our proposal, we provide some results to calculate these values by using a very simple mathematical model with less complexity.

This study compared the differences between a group that studied with AR contents and a group that studied in a traditional method to examine the effects of AR contents use in elementary school science classes. The effects in four areas of studying were examined : study focus rate, study activities consuming variables, study participation activeness and instructional climate. As a result, there was no significant difference in study concentration rate between the AR and traditional groups. For study participation activeness, the AR group had higher participation actions, but there was no difference between the groups for language participation. For study activities consuming variables, the AR group stimulated more diverse study activities than the traditional group. For instruction climate, the AR contents group contributed more to creating a positive climate compared to the traditional group. Therefore, the results showed that application of AR contents on science classes would stimulate active participation of students and various study activities and help create a positive instructional climate.

Angle concepts have a multifaceted nature such as quantitative aspects as the amount of rotation, qualitative aspects as geometric shapes, and relationship aspects made with planes or lines. This study analysed angle concepts and introduction methods of angles in elementary mathematics textbooks which have been used from the Syllabus Period to the 2015 Revised Mathematics Curriculum. First, the concepts of angles in mathematics textbooks focus through the definitions, representations, and components of angles presented in mathematics textbooks are analyzed. Secondly, how various aspects of each angle are sequenced through the tasks or activties in the introduction of lesson is looked. As a result of analysis, the methods of introducing angles in the changes of mathematics textbooks have mainly focused on learning about geometric shapes and relations of components. In the mathematics classroom, students should experience various aspects of geometric shapes, rotations, relational aspects of points, lines and surfaces, and support and link them to form a wide range of concepts.

The purpose of this study is to develop learning modules for environmental education using goal-based scenarios and to examine their pedagogical benefits at the elementary educational level. To enhance environmental knowledge, skills, attitudes, and behavior, this research developed learning modules relevant to three sub-dimensions of environmental education: education about environment, education in environment, and education for environment. In particular, this study provided useful educational strategies based on students' everyday lives. The developed modules consisted of three parts: 1) acquiring knowledge concerning the cause of global warming, 2) practicing and internalizing environmental knowledge in students' everyday lives, and 3) extending and disseminating environmental knowledge and awareness to other people. After applying the modules, the students acquired knowledge regarding the causes of global warming through discussions with their peers, and furthermore, exercised pro-environmental behaviors in their everyday lives. Moreover, the participants created UCC to urge other people to act for environment.

The purpose of this study is to explore the diversity of French learning materials and suggest a learning method to increase the efficiency of learning. In the first part, we explore the linguistic characteristics of the proverb. In the second part, we present the examples that can be utilized in actual learning. In terms of teaching methods, sharing a common cultural consciousness is important for language and communication between interlocutors. In view of this point, the proverb has an extremely important value in the linguistic dimension. It means that the proverb can serve as a very useful material for the comparison of the morphology and phonetics of French. The efficiency of learning can be increased if we can apply an adequate learning plan using proverbs in accordance to the learner's level and the learning contents.
