Abstract

This study aims to produce a three tier diagnostic test instrument of fraction topic for grade VII that feasible and valid, determine the feasibility of the instrument based on validity, reliability, and degree of difficulty, and reveal the misconceptions experienced by class VII students on fraction topic. This type of research is research and development. Research subjects from essay test trials, open-reasoned multiple choice tests, until the application of the three tier test instruments will be tested on students of class VII. The research procedure starts with a preliminary study, drafting a product, until product development is continued with the analysis of three tier tests in terms of validity, reliability, and the level of difficulty and analysis and interpretation of misconceptions from the results of the three tier test. The results of the study were obtained (1) the three tier test diagnostic instruments used to identify misconceptions in fraction number material were developed through preliminary study stages, designing essay tests, designing multiple choice tests, up to three tier tests; (2) the three tier tests developed meet the criteria of valid, reliable, and with a difficulty level of 6.7% easy, 26.7% medium, and 66.6% difficult; (3) students experience misconceptions on indicators explaining fraction definitions, comparing fractions of numbers, and calculating addition, subtraction, multiplication, and fraction division operations.

Abstract

This research aims to determine the influence of implementing the think talk write (TTW) strategy of cooperative learning model towards mathematics reasoning and communication abilities and students motivation in mathematics learning. The type of this research was a quasi-experimental study involving two different treatment groups. The population of this study were students of grade VII SMPN 1 Sinjai Utara and selected by cluster random sampling that were class VII-6 and VII-7. The results obtained from descriptive statistical analysis was: the mathematics reasoning abilities of students by applying cooperative learning model with TTW strategy is in low category, communication ability is in moderate category, and student learning motivation is in moderate category, and the mathematics reasoning abilities of students by applying direct learning model with expository strategy is in very low category, communication ability is in low, and student learning motivation is in moderate category. The results of inferential statistical analysis obtained that: mathematical reasoning, and communication ability, and the motivation of students by applying cooperative learning model with TTW strategy better than the mathematical reasoning, and communication ability, and the learning motivation of students taught by direct learning model. From the result of this research, it can be concluded that there was the influence of applying cooperative learning model with think talk write strategy to mathematical reasoning, and communication ability, and the learning motivation of students.

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.
