Abstract

Creativity is an ability that is needed in solving a problem. A person's creativity in solving problems can be assessed using three components namely fluency, flexibility, and novelty. Someone in solving problems can be influenced by the adversity quotient they have. There are three categories of adversity quotient namely quitter, camper, and climber. This type of research is a qualitative research method descriptive. This study aims to describe the creativity of elementary school students in solving contextual geometry problems based on adversity quotient. The subjects in this study were three people consisting of quitter subjects, camper subjects, and climber subjects. Data is collected through adversity Response Profile (ARP) tests, Problem Solving Tests (TPM) and interviews. The results showed that the creativity of subjects with the quitter category in solving contextual geometry problems was not able to achieve fluency, flexibility, and novelty. The creativity of subjects with camper categories in solving contextual geometry problems only achieves fluency and flexibility. Whereas the creativity of subjects with climber types in solving contextual geometry problems is able to achieve fluency, flexibility, and novelty.

Abstract

Indonesia has many cultures, one of which is in the form of traditional crafts namely Anyaman Bambu. It’s a form of traditional craft in the community that uses bamboo as its basic material. However, people only see these crafts as only a form of traditional craft, even though there are many motifs in these crafts that can be used as a starting point in learning mathematics, namely geometry transformations. Therefore, this research aims also to produce the learning trajectory of students in learning one subject in geometry transformations namely translation, which develops from informal to formal level through the Indonesian Realistic Mathematics Education (IRME) approach. The research method used is design research starting from preliminary design, design experiments, and retrospective analysis. This study explores how the motifs of Anyaman Bambu make a real contribution for ninth-grade students to understand the concept of translation. The results of design experiments show that the context of the motifs of Anyaman Bambu can stimulate students to understand their knowledge of the concept of translation. All the strategies and models that students find, describe, and discuss that show how students' constructions or contributions can be used to help their initial understanding of the translation.

Abstract

The research aims to analyze pre-service teachers’ perceptions about the application of the blended learning model in mathematics learning. The total research subjects were 254 pre-service teachers from 12 different universities in Indonesia. Furthermore, this research method is a survey with a qualitative approach where data are analyzed using the Rasch Model (WinSteps). The instrument of this study was a questionnaire consisting of 20 statements and divided into four indicators. Based on the wright maps table on WinSteps, women pre-service teachers prefer the blended learning model in learning mathematics than men pre-service teachers. Meanwhile, when viewed in terms of grade, fourth year pre-service teachers like the application of the blended learning model the most. In addition, it is also known that the most disliked thing in understanding mathematics by using blended learning is the difficulty to access assignments online and it requires internet quotas.

Abstract

A bilingual e-module that is systematically structured and linked to contextual problems can help students learn independently anywhere and anytime, especially in a pandemic that applies distance learning. RME is an approach that views mathematics as an activity/ process in contextual problems so that students find their own understanding. This study examines the feasibility of an RME-based bilingual e-module on 3D shapes with curved surfaces materials from expert judgment on material, language, and media. This research model is the ADDIE model. There are 6 validators (2 material experts, 2 media experts, and 2 linguists). The research instrument was in the form of assessment based on expert judgement. The results showed that both material, media, and language used for the RME-based bilingual e-module is "feasible” to use in mathematics learning.

Abstract

This study aimed at investigating the relationship between student’s algebraic thinking and cognitive style of Field Independent (FI) and Field Dependent (FD). The method implemented in the study is Group Embedded Figure Test (GEFT) which was intended to categorize students into the FI and FD styles. Afterward, to collect the data of students’ algebra thinking ability, a test was administered. The result of the test was compared to the result of GEFT test by integrating a computer program to find out the relationship between the students’ algebraic thinking and their cognitive styles, both FD and FI. The subjects of this research were the eighth-grade students totaling at 24 students. The findings of this study indicate that there is no relationship between manipulating symbols and students’ cognitive style.. There is a relationship between generalizing and formalizing and stundents’ cognitive styles. There is a relationship between using algebra as a tool and FD. There is a relationship between reasoning and representation and student’s cognitive style.

Abstract

The abilities that must be mastered by high school students according to the demands of the 2013 curriculum include reasoning. Students who have good reasoning abilities make it easier to understand mathematics. But in reality there are still many students who have low mathematical reasoning ability, seen when they have difficulty solving math problems. This research objective is to prove the habit of solving open-ended problems that can improve the mathematical reasoning ability of junior high school students based on the level of initial mathematical ability: high, medium, and low. The study used an experimental method with a "One-Group pre-test post-test design". Randomly, selected 77 grade VII students of SMP Negeri in Bekasi as a sample. The prerequisite test shows that each level of data comes from groups that are normally distributed and homogeneous. The results showed normal gain, both overall and level showed improvement. Based on the t test obtained p value of 0.000 < 0.005, meaning this study can prove student habits in solving open-ended problems when learning mathematics on triangles and quadrilateral, can improve students' mathematical reasoning abilities.
