Abstract

This study aims to determine the validity, practicality, and effectiveness of ethnomathematical-based worksheets with a scientific approach to improve students' mathematical problem solving abilities. The research type used is research and development with the ADDIE model. The validity test was carried out by using validator assessment data, the practicality test used a student response questionnaire, and the effectiveness test used a description test which was analyzed using N-Gain. The results showed that the worksheets developed were in the "Very Valid" category with a percentage score of 87%. Practicality test of LKS are "Very Practical" with a percentage score of 93%. The results of the LKS effectiveness test show an N-Gain score of 0.57 (Medium category) in improving student’s mathematical problem solving abilities (effectiveness criteria). It can be concluded that the ethnomathematics-based worksheets with a scientific approach to improve student's mathematical problem solving skills are valid, practical, and effective.

Abstract

Learning using the 2013 curriculum encourages students to have 4C abilities. The findings of the initial test results in class IX of SMP Negeri 3 Muntilan, their critical thinking skills were classified as poor. Mathematical disposition abilities influence the low and high level of students' mathematical critical thinking abilities. The findings from the initial questionnaire showed that mathematical disposition ability was in the medium category. Then, with the need for students not to get bored quickly and to be active when learning, the Problem Based Learning (PBL) model assisted by math cards was implemented. The research objective to be achieved in this study is to analyze in a multivariate way the critical thinking abilities and mathematical disposition abilities taught using the PBL model assisted by mathcards are better than those taught using the expository learning model on quadratic equations. The approach used is quantitative research with a quasi experimental design in the form of a non equivalent posttest only control group design. The results of this research are; Multivariately, students' critical thinking abilities and mathematical disposition are better in the PBL model assisted by mathcards compared to the expository model in quadratic equations. However, educators need to reconsider the material that will be applied with this mathcard-assisted PBL model, because this model is not necessarily suitable for all material.

Abstract

The mathematics literacy abilities are strongly needed for the students to be able to face educational challenges from the cognitive aspects. The students' mathematics literacy abilities can be viewed from various dimensions, one of whixzch is the learning styles. The purpose of this research is to analyze the students' mathematics literacy abilities in inferential statistics subject based on the learning styles. This is a qualitative descriptive research. The subjects of this research are the fourth semester students at a higher education institution in Magelang, Central Java, Indonesia, who are currently taking inferential statistics course. The instruments used in this research are test and interview instruments. The data analysis is carried out through data reduction, data presentation, and drawing conclusions. The students’ mathematics literacy abilities with divergent learning styles are only able to arrive at the formulating step. The students’ mathematics literacy abilities with convergent learning styles are able to take the mathematical literacy processes. The students' mathematics literacy abilities in the assimilation learning style have come to the interpreting step, but they have not been able yet to solve the problems well. The students' mathematics literacy abilities in the accommodation learning style have been able to understand and check (formulating and interpreting) well but in preparing plans or arguing (employing stage) in solving the problems, it has not been achieved yet properly. Based on the research results, it is found that each different learning style has its own different mathematics literacy abilities
