The problem of developing instructional materials for junior high-school general mathematics classes is a difficult one. Because of the diversity of interests and previous training of the pupils who are normally enrolled in these classes it is hard to find topics which are sufficiently interesting and general in their appeal to meet the needs of a majority of the pupils found in these classes.

The learning process in the classroom is said to be successful, if most students understand the concepts conveyed by the teacher. But, in the learning process, teacher found stundents has misconception. Misconceptions gotten by students, will affect students in the use of a concept between concepts in the mathematic. Identification misconception is one way to learning process get successful. The purpose of this research was for describe the misconception and the solution of student’s misconception of class IX Junior High School 2 Sedati Sidoarjo at the solve the problem of Pythagorean Theorem. The qualitative research was used as form of this research, with the type of case study research. The data collection technique which was used were 1) Test methods, 2) interview method. The technique of data validation uses triangulation of method, by comparing test result data and interview. The results of this research can be showed as there were three types of misconceptions experienced by students that was classificational misconceptions, Correlational misconception, and Teoritical misconception; (1) students take types correlational misconception. The indicator is writing units incorrectly. Before learning about concept Pythagoras Theorem, students master about unit concept.; (2) students take types classification misconception. The indicator is students missing determine side figure two and three dimentional to Pythagoras Theorem. In this misconception, students difficult illustration skew right triangle.; (3) students take types teoritic misconceptioan. The indicator is students missing giving the reason of problem. In this misconception is about triple Pythagoras concept. Student determine triple Pythagoras with calculate not with concept giving as multiples or formulas. By knowing the description of misconceptions that occur in students, teachers take the steps of the learning process accurately so student do not misconceptions

The Subject

This qualitative research aims to describe activity of students mathematical combinatorial thinking in constructing of the opportunity concept. The subject of the study is two students of Junior High School who had the ability in constructing concept. Data collection was obtained at the time of learning carried out based on learning plan as research instruments. The results showed a combinatorial thinking activity in constructing concepts. Counting processes are showen by students identifying dice and coins, solving theoritical opportunities problems with tables or diagrams, and solving empirical opportunities problems. Formulas/exspressions are showen by students being able to construct sampel points and sample space, construct theoritical opportunities concept, and make mathematical formulas of opportunities. Set of outcomes is showen by students being able to find the results of solving theoritical opportunity problems of one/or more dice and coins as well as the results of solving empirically opportunity problems.Keywords: combinatorial thinking, constructing concept, opportunity

Students Attitudes

The public outcry about students’ poor performance in mathematics can be said to have gained currency in recent times, in the dailies in Ghana. The outcry has been fueled by the fact that Ghanaian eight graders have always been among the least performing in international assessments such as TIMSS. Since available literature is replete with the fact that students’ attitudes of their mathematics classroom environment influence their attitudes to their classroom activities and hence their mathematics achievement, this study was designed to determine the attitudes of junior high school pupils towards their mathematics classroom learning environment. A total of 350 eighth and ninth graders (i.e., forms two and three junior high school students) from four public and two private randomly selected schools in a metropolitan community in southern Ghana participated in the study. The study adapted the mathematics attitude questionnaire (MAQ) instruments, a questionnaire designed to measure students’ attitudes of their classroom environment on four different subscales. The results revealed that, though in general, the attitudes of students were positive, that of the private school students were relatively more positive than their public-school counterparts in each of the subscales. Implications of this are discussed and recommendations for classroom teachers and future research are also presented.

Thinking Ability

We are in the era of big data, and it is particularly important to cultivate students’ data processing ability. Python is an important auxiliary tool for data analysis, and its syntax is concise and clear, which is suitable for junior high school students to start learning code language. Making full use of modern information technology and Innovating Curriculum form is the new requirement of “China education modernization 2035”. Integrating Python into junior high school mathematics classroom is not only the innovation of mathematics curriculum form, but also a good way to cultivate students’ thinking ability and programming thought. Based on the understanding of Python software and data processing plate in junior high school mathematics curriculum, this paper analyzes the promotion of students’ thinking ability by integrating Python into junior high school mathematics classroom, and explores the strategies of applying Python in teaching combined with cases.
