Abstract

This study is a descriptive study with qualitative approach which aimed to describe the mathematical problem solving abilities by Polya step terms of abstract sequential thinking style, concrete sequential, abstract random and concrete random. The subjects in this study are 4 (four) of students grade VIII SMPN 24 Makassar selected purposively based on the different of thinking style. Data collection tool is questionnaire to classify students based on the thinking style and to determine the subject, written tests and interviews to determine the ability of students' mathematical problem solving. Data were analyzed to describe the mathematical problem solving ability of students based on Polya steps namely; (1) understanding the problem, (2) devising a plan, (3) carrying out the plan and (4) looking back. The results showed that students' of premises concrete sequential and abstract random thinking styles has the same ability on the fourth problem solving step in understanding the problem, devising a plan, carrying out the plan and looking back on the process and results. While students with the type of abstract sequential thinking style and concrete random has a different problem solving steps on each of the four stages.

Abstract

This research is a quasi experimental research which aims to know the influence of cooperative learning model type multi representative discourse towards mathematics learning achievement of 7th grade students of SMP Negeri 5 Mengkendek, Tana Toraja.The population is students of SMP Negeri 5 Mengkendek academic year2017/2018. Sampling technique is cluster method, in this case selected 2 class as experimental class and control class. Data collection is observation sheet of learning implementation and test of mathematics learning achievement. Data analysis used SPSS statistical data processing program. The result of descriptive statistical analysis shows: (1) learning implementation by using cooperative learning model type multi representative discoursein very good category (2) the implementation of learning by using conventional learning model in very good category, (3) mathematics learning achievement of two classin high category, whereas in the experimental class obtained average score 85.74 with standard deviation 8.49 from the ideal score 100 and in the control class obtained average score 80.13 with deviation 6.45 from ideal score 100. The result of inferential analysis shows the learning achievement of students used cooperative learning model type multi representative discourse is higher than the result of student used conventional learning model.

Abstract

This research is a qualitative research with descriptive approach that aims to describe the characteristics of problem solving mathematics in terms of student cognitive style. The subjects of the study were students of class XI MIPA SMAN 8 Makassar consisting of 2 students with FI cognitive style and 2 students with cognitive style FD. instruments in this study are GEFT test, problem-solving test and interview guidance. Data collection is done through data analysis of written test of problem solving and interview.The results showed that: (1) at the stage of understanding the problem, the subject of the FI did not write down the known and the thing asked, while the subject of the FD wrote down the known and the question asked; (2) at the stage of making a problem-solving plan, the subject of the FI writes the formula or constructs an equation to be used in progress, while the subject of the FD compiles more than one problem-solving plan or solves the problem in various ways. In addition, the subject of FD tends to directly create an interface; (3) at the stage of carrying out the split plan, the subject of the FI includes data on the formula chosen in the planning stage or using the substitution-elimination method and completes it by algebraic operations (sum, subtraction, multiplication and division) to obtain a settlement of the problem, whereas the subject of FD includes data or values that are not derived from the problem into the formula chosen in the planning stage; (4) at the re-examining stage, the FI subject does not review the answer before collecting the answer sheets, while the FD subject re-examines the answer before collecting the answer sheets.
