Abstract

Mathematical communication skills are very important abilities possessed by students in the process of learning mathematics, especially in understanding mathematics. One important goal in mathematics learning is that students are able to provide arguments for their answers and provide responses to answers given by others, and what is being learned becomes more meaningful to them. Mathematical communication is essential from teaching, learning and acsess mathematics, we will need communication if we want to reach in full the purpose such as understanding. Therefore, it is very important to develop and improve students' mathematical communication skills in the learning process of mathematics. This study aims to examine the improvement of mathematical communication skills between students who get learning with contextual approaches and students who get conventional learning. This research is an experimental study using a pre-test post-test control group design. The population in this study were eighth grade students of MTsN 4 Pidie, Aceh in the 2018/2019 academic year. Through Purposive Sampling, two parallel classes were chosen, namely class VIII1 as the experimental class and VIII2 as the control class.

Abstract

Mathematical comprehension ability is a very important initial ability possessed by students in the learning process of mathematics, especially in understanding mathematics. One important goal in learning mathematics is that the material taught to students is not as memorization, but with understanding students can understand the concept of mathematical material. Mathematical understanding is one of the goals of every material delivered by the teacher, because the teacher is the student's guide to achieving the expected concept. Therefore, it is very important to develop and improve the ability of students' mathematical understanding in the process of learning mathematics. This study aims to examine the enhancement of the ability of mathematical understanding between students who obtain learning with a contextual approach and students who obtain conventional learning. This research is an experimental study using a pre-test post-test control group design. The population in this study were students of class VIII MTsN 4 Pidie, Aceh in the 2018/2019 school year. Through purposive sampling, two classes were chosen in parallel, namely class VIII1 as the experimental class and VIII2 as the control class. The instrument used to collect research data is a mathematical comprehension ability test. The statistical test used is the t-test to analyze the data for increasing the ability of mathematical understanding. The results of the study showed that the improvement of students' mathematical comprehension ability who obtained contextual approach learning was better than students who received conventional learning.

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 upgrading the understanding and solving mathematical problems high school students with cooperative learning model Team Assisted Individualization. This study is an experiment that is true experimental research with a quantitative approach. Design research is pretest-posttest control group design. The population in this study were all tenth grade students in the academic year 2013/2014. The sample in this study was 2 classes, X1 (control group) and X2 class (class experiment). Data collection using the test. Data analysis was conducted to gain a score normalized using ANOVA test with the help of SPSS 17.0 software and Microsoft Office Excel 2010. The results showed that: 1) Increased understanding of the mathematical ability of students who obtained using a model of cooperative learning type Team Assisted Individualization better than students which gained overall in terms of conventional learning and student level (high, medium and low), 2) There is 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 the cooperative model of Team Assisted Individualization better than students who received conventional learning is reviewed overall and student level (high, medium and low), 4) There is interaction between the learning model and student level (high, medium, and low ) to increase problem-solving ability.Keywords: Understanding Mathematical Ability, Mathematica lProblem Solving Ability, type Cooperative Team Assisted Individualization
