Abstract

This research aimed to determine whether the reciprocal teaching model affects the ability of students’ mathematical representation or not. The research design used was post test only control design. Sampling used cluster random sampling by taking two classes namely, class VII B as the experimental class and class VII A as the control class. The location of the research was SMP Negeri 6 Purwokerto. As for obtaining data used post test the ability of mathematical representation, the post test question in the form of description. Post test result of mathematical representation ability showed experiment calss average was 65.23, while control class equal to 59.31. Also it obtained the score of hypothesis testing using independent sample t-test as follows, Sig. = 0.051/2 = 0.0255 with 0.05 which means Sig < 0.05 or 0 H is rejected. It can be concluded that the reciprocal teaching model affecs the ability of mathematical representation. Keyword: Mathematical Representation Ability, Reciprocal Teaching.

Abstract

This study is aimed to describe how the efectivenees of PBL to develope mathematical problem solving skill in inferensia statistics learning. This study was a quasi experiment conducted on the odd semester in the academic year of 2014/2015. The research population was all the 3th semester of mathematics education department, Muhammadiyah University of Purwokerto ion inferensia statistics topic. From the population, two classes were selected as the sample. The selected classes were Class III B and Class III C. Class III B dealt with the PBL, and class III B dealt with the direct instruction. The instrument to collect the data was an essay test to measure the mathematical communication and problem solving skills. Kolmogorove-smirnov test was used to test the normality of the data and to homogenity test using Levene’s Test. The data were analyzed using independent t-test. The results of the study show that PBL efective to develope mathematical problem solving skill of the 3th semester of mathematics education department student, Muhammadiyah University of Purwokerto in inferensia statistic learning.

Abstract

ABSTRACT: This research is aimed to identify errors on working paper which is written by the students observed from mathematic communicative competence. This research is included descriptive research. The subjects of this research are the students of mathematic department that get remedial in lesson matematika sekolah 4. There are nineteen students. The data is taken from the working paper which is written by the students. The sample is taken using purposive sampling technique. The working paper that is used include: (1) statistic; (2) exponents and logarithms; (3) sequence and series. Based on the research can be concluded that: errors on working paper which is written by the students observed from mathematic communicative competence are: (1) inconsistencies and inaccuracies in using mathematic symbol; (2) unability in describing inequality solution; and (3) less capable in showing tables and informative issues. KEY WORDS: error identification, mathematic communicative competence

Abstract

Indonesia is known as a country with cultural diversity, one of which is the traditional house, a symbol of each tribe and region. In its implementation, the Joglo house is only used as a residence and a place to protect against exposure to sunlight. Still, after exploring it in more depth, the structure of the traditional house can be used as learning material in the field of education. One field of education that can study culture through the structure of conventional house buildings is mathematics. Learning mathematics that includes culture can help students improve their understanding of abstract mathematics. However, not many mathematics lessons incorporate culture into the material. So, this research aims to explore Banyumas Joglo houses regarding geometric concepts. The type of research used is qualitative research with an ethnographic approach. Data collection methods include observation, documentation and interviews. The data analysis consists of data reduction, data presentation, and conclusion. This research shows that the Banyumas Joglo traditional house is an example of a conventional house rich in ethnomathematics, where elements of traditional culture contain mathematical knowledge in the form of geometric concepts.
