Abstract

This study purpose to determine the ability of students to use Polya?s step in solving mathematical problems through Problem Based Learning. This study used a quantitative approach with a total sample, as many as 26 students of 7th grade of Junior High School 2 Kusan Hulu student. Problem Based Learning activities held in four meetings and two tests. The test results were analyzed based on the Polya?s problem solving steps, calculated with the percentage in each step. The results showed that the ability of junior high school students to use Polya?s steps in solving mathematical problem through Problem Based Learning was: 1) ability to understand problems at 83.80%, 2) ability to plan problem solving at 71.42%, and 3) ability to do counting at 75.61%.

Abstract

Mathematical learning tools that integrate culture are needed to bring the learning of daily life together so that it can improve students' problem solving skills in learning as well as in life. This is a hope to be achieved in the implementation of education in the province of Aceh. But the learning device is not available yet. So it takes effort to help teachers develop the learning device. Gayo is one of the sub ethnic in Aceh Province. This study aims to determine the process and results of the development of learning devices based on Gayo culture with a valid, practical and effective realistic approach. The development model used in this research is the development of Plomp which consists of three stages: initial assessment, design / prototype, and assessment. The subjects of this research are VII grade students of SMP IT Azzahra as small test also big test to judge valid, practical and effective. The results of this study obtained the tools of learning mathematics based on Gayo culture has met the valid, practical and effective criteria.

Abstract

Students were demanded to be a creative problem solver in the career world. A mathematical learning following an inquiry-based learning approach and integrating mathematical tools was developed in this study. Students constructed original solutions about trigonometry ratio by using a clinometer and a meter as mathematical tools in allowing creative thinking. The product was designed through ADDIE methodology and applied to two classes in a Senior High School. A pre-test and post-test design measured cognitive knowledge as creative thinking variable. The result showed that this product with using mathematical tools was feasible and successful in enhancing students? creative thinking. Inquiry-based learning was developed by involving three main components: providing students with a contextual mathematical problem-solving activity; involving student in an open-ended investigation with using a clinometer and a meter as mathematical tools to promote their creative thinking in creating original solutions; motivating students to build their own knowledge. This inquiry-based learning which had been developed significantly influenced students? pre-knowledge scores. It could be concluded that creative thinking contributed, too. A recommendation for mathematics teachers in teaching mathematics was to involve students in problem-solving activity that facilitated them to conduct open-ended investigation whereas they could construct their own knowledge in building an original solution.

Abstract

The purpose of this study is to improve the Habits of mind of students through the problem-based learning (PBL) model based on the otetic assessment of mathematics learning. The study was conducted on 39 students of class X. The research method used was an pre-experiment method. with One group pretest-posttest design. Data analysis carried out was Normality Test, Homogeneity Test, t Test, and N gain Test. The results of this study indicate that the application of authentic assessment-oriented PBL method can improve students' habit of mind in mathematics learning. This can be seen from the increasing results of assessment of creative thinking, and student self-regulated. the results of the creative thinking assessment are N-Gain values of 0.47 or included in the medium criteria and the results of the hypothesis test state that the significance is smaller than the reference sig it can be said that there are significant differences between the pretest and posttest values. The results of the assessment of self regulation, show the value of N gain 0.59 in the medium category so that it is said there is an increase between the value of the pretet results and the value of the posttest results.

Abstract

Mathematics is one of the important subjects in realizing the goals of education in Indonesia. However, in reality there are many students who have different problem solving abilities between one and the other and many students make mistakes when solving problems. The mistakes that are often carried out by students can also be influenced by differences in learning styles possessed. Therefore this article aims to describe differences in errors made by reflective-impulsive students in solving mathematical problems. This research is a qualitative descriptive that involving 2 research subjects with each subject having a different learning style. This research was conducted in class VII Pakusari Jember 1 Junior High School in the academic year of 2018/2019. The results of data analysis showed that differences in mistakes made by junior high school students with reflective-impulsive learning styles in solving mathematical problems were located at the stage of determining mathematical models and at the stage of completing mathematical models that had been made with the percentage of impulsive learning styles when compared to a subject that is reflective learning style.

Abstract

The purpose of this study was to Determine the implications of the results of this study on learning mathematics. The research of data were Obtained from observations, interviews with traditional South Bengkulu cake sellers, and interviews with mathematics teachers. The results Showed that various research activities Showed that the elements of mathematics in cultured activities could be implicated in mathematics learning items, namely looking for Certain patterns to Determine the elements in the circle and activities by using cultured Contexts students could find concepts in finding the circle area circle. Students' activities in finding concepts can develop critical and creative thinking and can improve the character of love in the local culture. So that teaching materials using cultural Contexts can be practiced and developed in mathematics learning in junior high schools (SMP) in the 2013 curriculum. This study produces a mathematical syntax with ethnomatematics learning approach.
