Abstract

This research was conducted to know the activity, learning result, and student's response to learning using Realistic Mathematics Education (RME) approach on multiplication counting material. This research is a Classroom Action Research which carried out three cycles. The subjects were 33 fourth grade students of SD Negeri 46 Banda Aceh. Data collection was done by using formative test of student learning result, student activity observation sheet, and student response questionnaire. The results showed that the expected student activity in the learning process was improved by using RME approach on multiplication counting material in class IV SD Negeri 46 Banda Aceh. There are 40% of active student activity, the second cycle is 80% active student activity, and in 100% cycle 100% active student activity. Furthermore there is also an increase in the ability of student counting operations multiplication in each cycle. The cycle-I is 33.3% complete, the II-cycle is 63.6% complete, and the III-cycle is 96.97% complete. Student response is also very positive on the learning by using PMR approach on the material of multiplication operation in class IV SD Negeri 46 Banda Aceh.

Abstract

Up to now the mathematical ability of students is still relatively low. It is characterized from the low mathematics learning outcomes. Low ability students' mathematical understanding and abilities among students' mathematical problem solving so we need a model of learning that can improve both the mathematical ability. Team Assisted Individualization (TAI) is one type of cooperative learning is expected to increase both these capabilities. This type combines the advantages of cooperative learning and individual learning. This study aims to assess about increasing the understanding and solving mathematical problems high school students with TAI type of cooperative learning model. This study was an experiment that was true experimental research with a quantitative approach. Design research is pretest-posttest control group design. The population in this study was all tenth grade students in the academic year 2013/2014. The sample in this study was two classes, class X1 (control group) and class X2 (experiment group). Data collection was using the test. Data analysis was conducted to gain a score normalized using ANOVA. The results showed that: 1) increased understanding of the mathematical ability of students who obtained using TAI type of cooperative learning model better than students which gained overall in terms of conventional learning and student level (high, medium and low), 2) there was no interaction between learning model and student level (high, medium, and low) to increase the capability of understanding, 3) improving students' mathematical problem solving ability the learning gained by using TAI type of cooperative learning model better than students who received conventional learning was reviewed overall and student level (high, medium and low), and 4) there was interaction between the learning model and student level (high, medium, and low ) to increase problem-solving ability.
