Abstract

The emergence of this research is based on the lack of mathematical skills of students, especially at the primary / MI. Lack of ability is one of them triggered by the selection and use of learning approaches that are less varied. This research is a quantitative research in the form of experiments. Data collection techniques used instrument of observation, interviews and tests. Analysis of data such as observation data and interviews conducted with descriptive analysis and quantitative data were analyzed using statistical formulas in the form of t-test with SPSS version 17. The results showed there are significant PMR approach to the learning outcomes of students in Class VA MIN 1 Padangsidimpuan.

Abstract

The purpose of this research was to describe the students? error in measurement materials in terms of learning style. This is a qualitative descriptive research. The subject of this research was 6 students with each of the two students in visual learning styles, auditory learning styles, and kinesthetic learning style. The research instruments were questionnaire, test, interview, and observations. Data analysis activities were data reduction, data display, and conclusion drawing/ verification. The technique of data analysis used interactive techniques with these three procedures. The result of this research showed that the students? error with visual learning styles in solving units, size, and time included material concepts errors and the use of mathematical unit; this is because teachers tend to use the lecture method in learning. The students? errors with auditory learning style in solving unit, size and time included in interpreting data, determining formulas and errors in counting. The cause of this error is not remembering the concept and hurrying in solving math problems. The students? error with kinesthetic styles in solving unit, size and time included student errors identifying elements and language interpretation, errors in language use, and conceptual errorst.

Abstract

AbstractMathematical representative is part of mathematicalcommunication. Mathematical communication ability is one of standard of process that still need for growing and students have it. This standard of process must say while process of mathematic learning. Mathematical representative is a picture, translator, act of expressing, reappointment, institutionalization, or modeling of idea, concept, concept mathematic, and relationship between one configuration, construction, or situation of problem which from the students in medley type as effort to get clarify meaning, showing of comprehending, or to look for solution of the problem which there in front of us. Representative is not also to show the result, or product of new configuration or construction, but also process of thinking that is done for getting and comprehending the concept, campaign, and relationship of mathematic from one configuration.Kata kunci: Komunikasi matematis, dan Representasi matematis

Abstract

Constructivism is a branch of philosophy which views knowledge as result of construction within human himself. He constructs knowledge through interaction with object, phenomena, experience and environment. Knowledge is considered true if it owns significance for problem solving. Learning in the view of constructionist offers to develop concept and perception from the students themselves.  In the classroom process, teacher takes roles as moderator and facilitator. A constructivist teacher required to understand the characteristics of students’ mistakes due to that knowledge improvement is through mistakes and errors. Teacher must view mistakes as source of information about students’ characteristics scheme and thinking. There are four principles of constructivism in mathematics learning. First, psychological structure must be previous to occupation of number. Second, background knowledge structure (schemata) must be developed before teaching mathematics formal symbols. Third, students must possess opportunities for finding and forming their own mathematics relations, not to expose to adult thought. Fourth, teacher must create thinking atmosphere in the classroom.

Abstract

The background of the problem in this study is the obstacles experienced by students of class VIII-4 at MTsN 2 Padangsidimpuan when completing the questions in the initial test. Obstacles found include students who are less able to understand the concept of social arithmetic well. Therefore, it is necessary to make an update in student learning activities, especially on the subject of social arithmetic. The formulation of the problem in this study is how the validity of learning trajectory is the subject of social arithmetic using a contextual approach and how practical learning trajectory is the subject of social arithmetic using a contextual approach. The purpose of this development is to know the learning trajectory validity of the subject of social arithmetic by using a contextual approach and knowing the practicalities of learning trajectory the subject of social arithmetic using a contextual approach. The discussion of this research relates to the field of mathematics. In connection with this, the approach taken is theories related to mathematics teaching and learning. In this case the learning trajectory developed refers to 7 main components of the contextual approach, namely constructivism, asking, finding, learning society, modeling, reflection, and authentic assessment. So that a valid and practical learning trajectory is used for students of MTsN 2 Padangsidimpuan.The type of research used is design research. Design research is included in qualitative research. Design research is research that places the design process as a strategy to develop a learning path. Trajectory learning designed is validated by 3 validators. The instrument used in this study is observation and questionnaire.Based on the results of the validation of the 3 validators obtained a value of 75.23% with a valid category. Learning trajectory practices obtained from observations made on student activities from the meeting were 66.125%, 66.625%, and 67.375%. The use of time used is sufficient and the results ofthe questionnaire obtained are 88.70% in the practical category. Thus, it was concluded that the development of learning trajectory on the subject of social arithmetic in MTsN 2 was aimed at a valid and practical contextual approach.
