Abstract

This study aims to find out and examine the comparison of the results of tests of students' mathematical problem solving abilities in the comparison material. The type of research used was quasi-experimental (not randomized class) taken 2 classes namely class A and class B to study the ability to solve mathematical problems of students in one of the junior high schools in Kabupaten Bandung Barat. Class A is the class that gets the learning treatment and class B is the class that does not receive learning treatment before the problem solving ability test. The instrument used in this study was a test of mathematical problem solving abilities. The population in this study were class VII students and the samples in this study were classes VII-G and VII-H. Based on the results of the analysis of research data, the average value of class A is 79.84 and the average grade B value is 58.55. Problem solving analysis on indicator 1 can be said that students have been able to identify all known elements, asked questions and adequacy of elements, on indicator 2 students have been able to show strategies used to solve problems, on indicators of 3 students who have been able to do calculations and decision making. It can be concluded that the results of the test of problem solving ability of comparative material, the class given the treatment of learning is better than those not given the learning treatment

Abstract

This study aims to determine the extent of high school students' mathematical problem solving abilities. The method used in this study is descriptive with a qualitative approach. The population in this study were all high school students in West Bandung Regency, while the sample was 20 students of class XI in one of the high schools in West Bandung Regency. The results obtained from this study indicate that the percentage of indicators 3 chooses and applies strategies to solve mathematical problems or outside mathematics and indicator 4 explains or interprets the results according to the problem and checks the correctness of the results or answers, gets the lowest percentage with 60% and 31%. Then the students' mistakes in solving the problem of mathematical problem solving ability lies in the process of selecting and implementing a calculation strategy and students have not been able to elaborate on the strategies that will be carried out to carry out the next calculation. Based on the results of student answers, it can be said that the level of problem solving ability of students in one of the high schools is quite sufficient even though they still have many difficulties in working on the questions on indicators 3 and 4.

Abstract

Mathematical reflective thinking ability is a process of thinking someone in understanding, identifying, analyzing problems based on relevant information and determining solutions to solve these problems. The importance of reflective marriage is to help students develop high-level thinking skills through their encouragement to: 1) connect new knowledge to their previous understanding. 2) thinking in abstract and concrete terminology. 3) apply specific strategies for new tasks. 4) understand their own thinking processes and learn on their own. The research method used is descriptive qualitative. The population of this study was all junior high school students in the city of Cimahi, which became the sample of this study were students of class VII-H at Cimahi Middle School 8. The instruments of reflective thinking ability were given to students as many as 5 questions for written tests accompanied by interviews with each student. Then the results obtained are the level of mathematical reflective thinking ability of junior high school students in Cimahi City based on written tests and the results of interviews with Cimahi students are still relatively low and there is no influence between student self-independence and mathematical relative thinking skills.
