AbstractThis study aims to improve students' problem-solving abilities with STAD cooperative learning model on the subject of integers class VII SMP Negeri 3 Galang. This type of research is a classroom action research. The subjects were students of class VII-1 SMP Negeri 3 Assemble TA2014/2015 which amounted to28 students. The object of this study is an effort to improve the ability of mathematical problem solving through cooperative learning model Student Team Achievement Division(STAD) on the subject of Integer. The research instrument used is the observation and mathematical problem solving ability test. From the results of problem solving ability test, the data obtained were 9 students (32.14%), which reached the criteria of problem-solving abilities. After being given the treatment by applying the learning model STAD (first cycle), it is provided TKPMI .From the TKPMI data showed that as many as16students(57.14%) of the28students(2.74 value) that reaches criteria problem-solving abilities. This shows that in the first cycle of mathematical problem solving ability of students as a whole h as not reached 85%, the continued action on the second cycle. From the results TKPMII data showed that as many as 24 students (85.71%) of the 28 students (3.15 value) that reaches criteria problem-solving abilities. This shows that the mathematical problem solving ability of students as a whole has reached 85%, then the action is stopped. Based on t he above results, it can be concluded that by applying STAD cooperative learning model can improve students' mathematical problem solving ability on the subject of integers in class VII SMP Negeri 3Galang.Keywords: STAD, improve, test, problem, solving

This study aims to describe students' mathematical problem-solving abilities based on mathematical dispositions at Riyadlul Mukhlishien Middle School. This type of research used in this research is descriptive qualitative. The research subjects used were 21 students of class VIII A. The data sources of this research are in the form of questionnaires, test descriptions and interviews. The results of the questionnaire were used to classify the level of students' mathematical dispositions. After that, two students from each category of mathematical disposition were selected to be the subject of tests and interviews. The results of tests and interviews of mathematical problem-solving abilities were analyzed based on the mathematical disposition of the students. The results of this study indicate that the mathematical disposition of SMP Riyadlul Mukhlishien students is divided into three categories, high, medium and low. Students who have mathematical problem-solving abilities in the high mathematical disposition category are able to meet the indicators of mathematical problem-solving abilities well and write them down completely. Students who have mathematical problem-solving abilities in the moderate mathematical disposition category are able to meet the indicators of mathematical problem-solving abilities but do not write them down completely. Students who have mathematical problem-solving abilities in the low mathematical disposition category are less able to meet the indicators of mathematical problem-solving abilities because they do not write them down completely and still experience errors in calculations

ABSTRACT The purpose of this research was to know whether contextual teaching and learning (CTL) approach could improve students’ mathematical problem solving ability (SMPSA) in eighth grade of SMP Negeri 1 Binjai. The type of this research was Classroom Action Research. The subject of this research was students in class VIII-9 which consisted of 20 students. The object was SMPSA on cube and cuboid topic in eighth grade of SMP Negeri 1 Binjai Academic Year 2015/2016.This study consisted of two cycles. Each cycle had two meetings. SMPSA was tested in the end of cycle. Instrument used to collect data in this research were test and observation sheet. After giving a treatment to students, in the first cycle, the average score of their mathematical problem solving ability was 2.30. Ten of 20 students (50%) obtained score ³ 2.67. The average score of teacher’s activities in observation sheet was 2.66, which classified as good category. The average score of students’ activities in observation sheet was 2.55, which classified as good category. In the second cycle, the average score of mathematical problem solving ability was increased became 3.05 with 18 students (90%) obtained score ³ 2.67. The average score of teacher’s activities in observation sheet was 3.44, which classified as very good category. The average score of students’ activities in observation sheet was 3.22, which classified as very good category. From the result of research, it can be concluded that the implementation of contextual teaching and learning (CTL) approach can improve students’ problem solving ability. The suggestion that given for teachers is to be able to implement contextual teaching and learning (CTL) approach as an alternative in learning process that can improve problem solving ability.Keywords : Contextual Learning, Mathematical Problem solving Ability

The process of solving problems carried out by students in stages, namely understanding problems, planning solutions, carrying out solutions and checking again. Solving student problems varies according to the basic characteristics of students' interests, talents and potential. Learning will be more optimal if it is adjusted to the intelligence possessed by students. The goal is that teachers can facilitate learning according to the intelligence possessed by students, so the teacher must know the intelligence possessed by students. This research is a qualitative study using two subjects, namely the subject of linguistics and the subject of mathematical logic. The results showed that at the problem-understanding stage, SLM completed using formulas, completed according to plan and checked by recalculating. SL uses more trial-and-error reasoning, understanding information by reading sentences quickly as well as checking again.

Type a descriptive qualitative research. Instrument and data collection that is used in the form of Test anxiety now, GEFT, math test and interview. Data analysis techniques used, namely the reduction of data, data presentation, data verification and withdrawal of the conclusion. Research results: 1) the stylish Subject of cognitive ability in resolving the problem FI i.e. analytical and clear, but there is confusion on step completion caused high anxiety. 2) FD Subject in resolving problems i.e. thorough thinking because anxiety low was able to complete the issue hadn't yet high anxiety while still think dabble so can not solve the problem completely. 3) link between cognitive style and anxiety seen in a mathematically solve problems I on righteousness calculations and measures penyelesainnya. While the mathematical anxiety cognitive style is influenced by the FI and FD is seen in resolving problems, a subject that has broad perceptions of analytic and so was able to resolve the problem, while the subject is more intuitive, FD presepsi narrow and unable to resolve the problem completely

Problem-solving ability is one of the objectives to be achieved in mathematics. This capability is not only used in solving problems related to the field of mathematics, but can be used in solving the problems faced by students in the day-to-day life. One way to develop this ability in mathematics learning is learning by problem posing approach. This approach gives the opportunity for students to formulate questions that are simpler than the available problems. This research aims is to improve the ability of mathematical problem solving of students of grade VIIA, Junior High School of Muhammadiyah 9 Yogyakarta through learning “problem solving”. This is a classroom action research; with the subject of the research were seventh grade students of Junior High School of Muhammadiyah 9 Yogyakarta.
