Abstract

This study is a preliminary research on how students understand patterns. Students' understanding of something is a cognitive phenomenon as, according to information processing perspective, an integral part of the stimulus, receiving, encoding, storing and retrieving information. This paper aims to describe the information processing by students when they interpret the graph as a task that was delivered using takjil context. There are 9 seven graders aged 11-12 years in various mathematics ability that three students in each its category high, mid and low. It was found that: (1) The graph given in the task attract students' attention with various reasons. (2) The level of abstraction and processing is in accordance with students' mathematical abilities. (3) The number of words related to the context activated at certain period was determined by reviews of their experiences with similar contexts. (4) Concepts of a new schemes were not solely determined by the students' mathematical abilities. Broadly, this study recommends students to have learning experiences through varying contexts and gain extensive experiences to develop appropriate and useful cognitive schemes for solving problems.How to CiteMampouw, H.

Abstract

Every student in solving mathematical problems in the form of story problems has a unique solution. This uniqueness encourages research conducted to describe the problem-solving ability of social arithmetic stories by junior high school students from Polya stage. Stage Polya consists of understanding the problem, making plans, implementing plans and re-checking. The approach of this research is descriptive qualitative with subject as many as 3 students of class VIII SMP namely that each one student with different level of ability. The results show that high-ability students can go through all stages of Polya. Moderate students can only go through 3 stages namely, understand the problem, make plans and make plans. This student can not solve the problem correctly and there is an error in the calculation. Low-ability students can not pass through all stages Polya, because this student does not understand what is known and asked from the problem so that in the next stage can not be through it. It is expected that this research become one of the reference to optimize student problem solving abilities.

Abstract

Generalization is a reasoning in making conclusions that contain symbolism and are general. Semiotics have an important role in the process of generalization, in which generalize the pattern not only seen from the work of students but based on the process of students in understanding and making things. This paper aims to describe how junior high school students generalize patterns based on semiotic perspectives. The type of this research is descriptive qualitative in which data obtained by test, interview and observation. The subjects consist of 3 students of grade VIII junior high school students of 1 high, moderate, and low mathematics students. The findings of this research are at the factual stage the three subjects have the same gesture and word. But in the contextual phase each subject has a different way or step of work in accordance with the understanding possessed by each subject and the last stage of the symbolization of the three subjects can create the same formula. This paper is expected to be used as a reference for teachers to understand the ability of students in the generalization process.

Abstract

The study aimed to describe the cognitive ability of junior high school students in answering questions on  whole and fraction numbers based on TIMSS domain. This is a descriptive qualitative research involving three junior high school students with high mathematical ability as the subjects, i.e.: KV, DA, and TE. The data colletion instruments were TIMSS questions on whole numbers and fraction and the interview guidelines. The data were analyzed by using TIMSS cognitive domain in the sections of knowing, applying and reasoning. The results indicated that the knowing stated in written by KV and in mind by DA. Meanwhile TE?s ability was limited to compute fractions and measure. While KV applied mathematical concepts in written, DA and TE applied them verbally. TE was less accurate in using the concept of whole numbers. In the context of reasoning, KV was able to propose various solutions, DA had a single solution to fraction qeustions, and TE was confined to fraction questions. The subjects made their conclusions only in written.

Abstract

This research aims to produce ardgotic learning media that can improve student learning outcomes on logarithm.  This research consists of 5 development steps, namely analysis, design, development, implementation and evaluation. Ardgotic is a game developed from an othello type board game that requires players to win the games where logarithm is the topic. The results of this media validation reached 94.54%. Trials on 32 students of class X SMK showed a practically rate of 85.71%, both of which were in the very good category. The use of ardgotic media can improve learning outcomes logarithm by 0.697 or a moderate increase. Students find the appearance of the media attractives and the media can motivate them to learn logarithms. These results indicate that ardgotic media can be used to learn mathematics in different ways.
