Mathematical Problems

Reflective thinking ability is the ability of students to answer a given problem actively and carefully to obtain a more appropriate solution. This study is set to determine the reflective thinking ability of junior high school students in solving mathematical problems viewed from self-confidence. This research employs descriptive qualitative methods using questionnaires, written tests, and interviews in collecting the data. The subjects are six students of eight grade of State Junior High School 2 Pleret. In selecting the subjects, the researchers use a questionnaire that divides students into three categories namely, high, moderate, and low self-confidence. The results reveal that students with high self-confidence already have reflective thinking ability because they can understand the information well and be careful in solving problems. The students with moderate self-confidence have not been able to evaluate the problems because they do not carefully rechecking the obtained answers. The students with low self-confidence can’t identify problems clearly and correctly, can’t remember their initial knowledge to solve new problems, can’t evaluate problems, and can’t draw conclusions from a given problem.

Thinking Ability

The ability to think critically is one of the highest levels of ability. Developing critical thinking skills in students is still considered important to be improved in schools so that students are able and accustomed to facing various problems around it. This study aims to analyze the critical thinking skills of junior high school students who are in excellent classes and regular classes. This research was conducted in Bandung Barat. In this study students are given a test in the form of questions with critical thinking skills, the problem is used to compare between the superior class and ordinary class. Assessment of the problem using several factors of critical ability include 1) students can not understand the problem correctly, 2) students rush in doing the problem, 3) the students cannot choose the problem-solving strategy correctly and 4) the students work on the problem systematically. Then the matter of critical thinking skills of mathematics is analyzed using quasi-experimental research method to analyze students' critical thinking ability that influence learning result. This study shows the differences in critical thinking ability of junior high school students who are in excellent class and ordinary class. This study shows that superior classes are better in mathematical critical thinking ability than a regular class. The results of this study can add knowledge about critical thinking mathematics junior high school students who are in the class and ordinary class and used to facilitate for educational practitioners in the development of critical mathematical thinking skills.

And Function

This research tries to analyze the mathematics learning difficulties of Junior High school students on the material of “ relation and function”. This research was conducted on the grade VIII students in one of Junior High School 1st semester in Surakarta city in the academic year 2016. Mastery of students to the concept of mathematics which is the basic science of all sciences is still lacking. The results of the national exam of junior high school students of Surakarta are still low, one of which can be seen from the absorption of material relations and functions. This is because the results of National Examination for the city of Surakarta, can be seen from the absorption of UN value in 2015 with indicators to solve problems related to the function of 57.23%, while the year 2016 with indicators determine the value of the function if the formula of the known function of 52.70 %. This study uses test methods and interviews to find out the learning difficulties and their causes. Based on the test and interview on 3 Junior high school students who have high, medium and low learning achievements, it is found that students got difficulties in determining the value of function and value of x, if the image of x is known. Students get difficulty in solving problems related to the function and determine the value of the function and determine the value of x if the image of x is given. By knowing the difficulties faced by students expected teachers can find ways to overcome difficulties faced by students so that will be able to improve students' understanding of the material relations and functions.
