Abstract

Penelitian ini bertujuan untuk mengetahui efek dari permainan tepuk tangan secara bersamaan (tepuk bergilir), yang berorientasi konstruktivisme yang valid dan praktis, dalam pembelajaran konsep Kelipatan Persekutuan Terkecil (KPK) siswa kelas IV SD. Pembelajaran yang dilakukan dalam penelitian ini, dibawakan oleh Nila, Sasa, Rully, ditemani oleh bu Neti, selaku guru kelas, dan diikuti oleh 23 siswa. Sebelum memulai pembelajaran, didapatkan informasi, bahwa bu Neti telah mengajarkan materi kelipatan kepada siswa. Sehingga, disain pembelajaran dimulai dengan me-review kembali materi kelipatan, dengan permainan “tepuk bergilir”, kemudian memandu mereka untuk lebih memahami apa itu kelipatan. Selanjutnya, level permainan ditingkatkan, dengan membagi siswa menjadi 2 kelompok dan melakukan permainan diatas secara bersamaan, yang bertujuan menggiring siswa ke arah pembelajaran persekutuan. Akhirnya, pembelajaran ditutup dengan mencari bilangan terkecil dari persekutuan bilangan sebelumnya, sehingga di dapat nilai KPK dari 2 bilangan yang diberikan. Hasil-nya, siswa mampu memahami pelajaran KPK dengan baik dan mampu menyelesaikan soal-soal yang diberikan.

Abstract

Several previous researches showed that students had difficulty in understanding the basic concept of multiplication.  Students are more likely to be introduced by using formula without involving the concept itself. This underlies the researcher to design a learning trajectory of learning multiplication using Permainan Tradisional Tepuk Bergambar (PT2B) as a context based on the student experience. The purpose of this research is to look at the role of PT2B in helping students understanding in learning multiplication, which evolved from the informal to formal level in third grade with Pendidikan Matematika Realistik Indonesia (PMRI) approach. The method used is design research starting from preliminary design, teaching experiments, and retrospective analysis. This research describes how PT2B make a real contribution to the third grade students of SDN 179 Palembang to understand the concept of multiplication. The results showed PT2B context can stimulate students to understand their  knowledge of the multiplication concept. The whole strategy and model that students discover, describe, and discuss shows how the students construction or contribution can uses to help their initial understanding of that concept. The stages in the learning trajectory of student have an important role in understanding the concept of the operation number from informal to the formal level.  Keyword: Design Research, PMRI, Multiplication, Permainan Tradisional Tepuk Bergambar

Abstract

The aim of this study is to analyze students’ Adversity Quotient (AQ) in mathematics learning viewed from gender aspect. This study is quantitative survey study on students in MTs Al-Munawarah Boarding School, Pekanbaru. The subjects of study are 8th grade students consisting of  75 girls and 63 boys. Data are collected by AQ scale and analyzed with statistic descriptive and inferential (test-t). The indicator of AQ consist of control, origin, ownership, reach and endurance.  The result of descriptive analysis shows that there is difference in mean of each indicator for two groups, but analysis of test-t  shows that there is no difference in students’ mathematical AQ for two group of gender. Through variance test, students’ mathematical AQ in two groups is homogeneous. The indicator of AQ in boys which is categorized as high are endurance and reach. While, the indicator in girls is aspect of control. This study contributes to literature study in identifying students’ AQ and the effort done to enhance students’ AQ in mathematics learning.

Abstract

This article aims to investigate how mathematics education students in Universitas Ahmad Dahlan solve PISA mathematics problems. This research used the descriptive method with the qualitative approach and supported with quantitative data. Research subjects were 20 new students of mathematics education at Universitas Ahmad Dahlan in the 2016/2017 academic year. We translated the 2012 PISA instrument and used it to collect data on students’ mathematical literacy skills and to identify their difficulties. All the data were analyzed based on PISA’s framework. The result shows that, in general, 65.7% of students were able to understand the problems and plan their strategies to solve them. Meanwhile, only 46.9% among them could answer correctly. In addition, only 36.8% of the students were able to understand the level 6 problems while only 23.7% among them answered correctly. The students performed well in the interpretation process towards the problems with individual and social contexts. However, they found difficulties in the formulation and employment process of the problems, especially in the work and scientific context.

Abstract

This research aims to test the effectiveness of the Team Accelerated Instruction (TAI) towards the ability of the students to solve mathematics problems based on their initial ability. This study is an experiment with 367 students involved as the research sample taken using the cluster technique. The research variable is the problem-solving ability, the initial ability, and the learning model. Analysis of variance was used to analyze the data which leads to the conclusions that (1) the TAI is more effective than the Direct Instruction (DI); (2) the students having moderate initial ability performed better compared to the lower and the higher initial ability; (3) among the students with moderate initial ability, TAI was more effective to be used than DI; and (4) in the implementation of  TAI and DI, the problem solving ability of the students is relatively similar.

Abstract

Several studies on learning mathematics for rural areas student indicate that students have difficulty in understanding the concept of division operation. Students are more likely to be introduced by the use of the formula without involving the concept itself and learning division separate the concrete situation of learning process. This underlies the researcher to design division operation learning in the Mathematics of GASING (Math GASING), which always starts from concrete to abstract level. The research method used is a design research which describes how the Math GASING make a real contribution of students understanding in the concept of division operation.

Abstract

This research aims to determine differences in mathematical critical thinking skills between students who obtain mathematics learning using Problem Based Learning (PBL) and Guided Inquiry model. The research method used quasi-experimental with matching-only posttest-only control group design which implemented in one of the Junior High School of Yogyakarta. The instrument used is a valid test instrument namely posttest with descriptive evaluation. The result of this research showed that there is a difference of mathematical critical thinking skills between students who obtain mathematics learning using PBL model and students who obtain mathematics learning using guided inquiry model. Furthermore, the average of mathematical critical thinking skills between a student who obtains mathematics learning using problem based learning model is higher than students who obtain mathematics learning using guided inquiry model.
