The ability of mathematical representation is one of the abilities that must be possessed by students in learning mathematics. In fact, students 'mathematical representation ability is still relatively low, so we need a learning model that can improve students' mathematical representation abilities, namely Model Eliciting Activities (MEA) with STAD type. The purpose of this study is to compare the mathematical representation ability of students taught using MEA with STAD type and those taught with conventional learning. The approach to be used is a quantitative approach with a quasi-experimental research method and using a control group pretest-posttest design. The population in this study were all VII grade students. Sampling was done using simple random sampling, which consisted of two classes, class VII1 as the experimental class and class VII2 as the control class. Data collection is used by using a mathematical representation ability test sheet. The data analysis technique used is independent t-test. Based on these analysis it can be concluded that the mathematical representation ability of students taught using MEA with STAD type is better than conventional learning.

This article presents the results of quasi-experimental research design with pretest-post test control group to assess the ability of the mathematical representation student’s using experience-based learning model of type Knisley-Mulyana. The study was conducted on student of junior high school. Two classes were randomly selected to serve as the study sample. Students in experimental class get Knisley-Mulyana learning, while students in the control class get the conventional learning. There are two main instruments used, namely the ability test of mathematical representation and questionnaires. Questionnaires used to evaluate the response of students towards learning with Knisley-Mulyana model. The Results showed that students who acquire the learning of mathematics by using Knisley-Mulyana model provide a achievement of the mathematical representation capability better than students who received conventional learning. Viewed from the mathematical skills, students in the high group and low group with Knisley-Mulyana learning achieve their ability of mathematical representation better than students in the same group who received conventional learning. In other words the most effective group of students in the application of Knisley-Mulyana learning is a high and low groups. In addition, students responded well to learning by using Knisley-Mulyana model.Key words: Knisley-Mulyana, Mathematical Representation

<p>Mathematics is important and applies to science, technology, society or the natural sciences. It is applied directly or indirectly. Most students find this to be a very stimulating, complex, and well-understood subject. Maths in high school is extremely important. The study was designed to investigate the impact of students' mathematical representation skills and their attitudes towards GeoGebra. This study was quasi-experimental and carried out on high school students. We have two groups belonging to the same standard class. The control group consisted of 22 students, while the experimental group consisted of 28 participants. The conventional approach was used to teach certain concepts of plane geometry to the students in the control group. On the other hand, the experimental group taught similar teachings using GeoGebra. The results show that students have more skills in mathematical representation using GeoGebra. The semi-empirical test also showed a significant change in students' attitudes between the pre-test and the post-test. Students are more active in mathematical representation skills in GeoGebra.</p><p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/edu_01/0967/a.php" alt="Hit counter" /></p>

This study aimed to analyze the use of stocklab game to improve students' understanding of the stock market. This research was a quasi-experimental study with a nonequivalent control group design. The object of this study were students of class X IPS in MAN Surabaya. Class X IPS 2 was determined as the experimental class while class X IPS 3 as the control class. Both classes were given the same treatment using cooperative learning methods make a match type and numbered head together, however in the experimental class, games were given in the form of stocklab games. The analysis technique used to test the research hypothesis was one way ANOVA. Hypothesis tested by comparing the pre-test and post-test scores in both classes. Based on the analysis results, it was known that there were differences in students' understanding of the control class and the experimental class, where the understanding of the experimental class students tend to be better than students in control class. In addition, students also tend to understand more stock market terms.
