The researchers set up a research question to find out how to teach the concept of a right triangle through classification activities after listening to the conversations of fellow teachers about the recently revised textbooks. First, a questionnaire was created to confirm the objectivity of the research problem, data were collected through online and offline, and interviews were conducted with some of the respondents. As a result, it confirmed that there was a considerable difference in the perception of the research study about the direction of revising the curriculum called 'student participation centered' and 'the possibility of achieving the learning objective'. Then, we analyzed the critical interpretations used in the third grade math textbook Lesson 2. 'Plane Figure' part 4 and 5. Finally, by analyzing the results of the recognition analysis and textbook analysis, we proposed two learning methods which can link the triangle classification activity and the right triangle concept. Based on the results of the research, we obtained suggestions that a teaching should be made regarding that the classification process may be changed according to the student's prior knowledge and the process of classification activities may be different according to the viewpoint and classification criteria.

In this study, the types of inquiry activities in the $5^{th}$ & $6^{th}$ grade science textbooks according to the 2015 revised science national curriculum were analyzed and compared according to grade level and science area. Science textbooks for elementary school $5^{th}$ & $6^{th}$ graders contain quite diverse types of inquiry activities, which are student-centered inquiry activities. There were comparatively higher proportions of inquiry types such as experiment & observation and simulation, but relatively lower of inquiry types of investigation-discourse & presentation, discussion, expression. Elementary science textbooks are expected to cultivate science key competencies for elementary school students. Considering the science area, the motion & energy, substances, earth & space, and integration areas had the most experiment & observation among activity types, while the life area had the most simulation activities. Even in some area of the 6th grade science textbook, there was little or no data interpretation, discussion, and simulation activities. In order to achieve the goal of elementary science education, science textbooks should be developed considering the revision of future elementary science curriculum.

2015 개정 과학과 교육과정의 생명과학II 교과서에 수록된 탐구활동 유형을 추출하여 6개의 대단원과 5종의 출판사별로 비교 분석하였다. 탐구활동 유형 중 조사 토의 및 발표(IP)의 수가 많이 늘어난 것과 표현하기(EX)가 각 단원마다 수록되어 있다는 것은 2015 개정 교육과정에서 지향하는 교실 수업을 학생중심활동으로 전환하기에 충분한 것으로 해석할 수 있다. 실험 관찰, 모의 활동, 조사 토의 및 발표 등의 학생중심 활동 영역의 탐구활동 유형이 2009 개정 교육과정의 약 27% 정도를 차지한 것보다 증가한 약 41% 정도를 차지하였다. 그러나 여전히 자료 해석 유형이 가장 많기 때문에 앞으로 교과서 개발이 필요할 때 학생들의 창의성과 사고력을 신장시키기 위해서 자료 해석의 유형을 줄이고 모의 활동이나 표현하기의 유형이 더 늘어나도록 해야 할 것이다. 교사들은 생명공학 기술의 발전뿐만 아니라 교과서마다 각기 다른 다양한 과학 소재를 재구성한 후 학생들에게 활용하여 균형 잡힌 사고를 유도하고, 표현력, 창의력, 논리력, 비판적 사고력을 신장시키기 위한 노력이 필요하다.

Fourteen Special high schools for developing talents in Science, Foreign Languages, and Arts in Seoul Metropolitan city were analyzed in terms of their educational objectives, Students screening system, curriculum, teaching-learning methods, teachers, and consistency with higher education. Special high schools in talent area were more or less similar to each other in all the above aspects. However, special high schools in different talent areas were quite different in student screening, teaching-learning methods, teachers, and consistency with higher education. Public schools were more affluent than the private ones. Special high schools in Science, arts and Sports were providing individualized, activity oriented, process-oriented teaching-learning methods, while the Foreign languages high schools excercised teacher-centered, grammar oriented, lecture-focused teaching methods more. Special high schools in arts and sports could have consistency with higher education because the university focuses on talents in the specified field rather than academic scores. In conclusion, the schools have a great deal of rooms to improve in teaching-learning methods with which students can maximize their potential development. However, the special high schools were equipped with better learning environments than regular high schools in many aspects.

Recently, the importance of participating in classes activity and cultivating student's thinking ability is emphasized in the mathematics education society. Teachers are demanded to change their teaching style centered pencile-and paper into using the variety instructional aids, such as calculator, video tape, computer, ohp, and projector, etc. In this paper, we search for the mathematica's function and the method that apply mathematical to the secondary school mathematics. Mathematical has many functions: calculator, algebra, graphics, animations, programing, notebook. We find that mathematica can be applied to the graph of function, the understand of simultaneous equations, the graph of trigonometry function, the calculation of limit, the computation of areas as limits, the derivative of a function and tangent line, a solid figure, and others in secondary school mathematics.

In mathematics education, teaching-learning activity can be divided largely into the understanding the mathematical concepts, derivation of principles and laws, acquirement of the mathematical abilities. We utilize various media, teaching tools, audio-visual materials, manufacturing materials for understanding mathematical concepts. But sometimes we cannot define or explain correctly the concepts as well as the derivation of principles and laws by these materials. In order to solve the problem we can use the computer. In this paper, character and movement state of various quadratic function graph types can be used. Using the computers is more visible than other educational instruments like blackboards, O.H.Ps., etc. Then, students understand the mathematical concepts and the correct quadratic function graph correctly. Consquently more effective teaching-learning activity can be done. Usage of computers is the best method for improving the mathematical abilities because computers have functions of the immediate reaction, operation, reference and deduction. One of the important characters of mathematics is accuracy, so we use computers for improving mathematical abilities. This paper is about the program focused on the part of "the quadratic function graph", which exists in mathematical curriculum the middle school. When this program is used for students, it is expected the following educational effect. 1, Students will have positive thought by arousing interests of learning because this program is composed of pictures, animations with effectiveness of sound. 2. This program will cause students to form the mathematical concepts correctly. 3. By visualizing the process of drawing the quadratic function graph, students understand the quadratic function graph structually. 4. Through the feedback, the recognition ability of the trigonometric function can be improved. 5. It is possible to change the teacher-centered instruction into the student-centered instruction. For the purpose of increasing the efficiencies and qualities of mathmatics education, we have to seek the various learning-teaching methods. But considering that no computer can replace the teacher′s role, tearchers have to use the CIA program carefully.
