Abstract Simulations provide unique features and instructional benefits for the improved understanding of concepts. This study aimed to find the effect of computer simulations on the understanding and retention of mathematical concepts. This was an experimental research. A sample of 100 students participated in this experimental research.  The sample was further distributed into an equal number of students in two groups. Some topics were selected from the grade–IX mathematics textbook. The selected mathematical topics were taught to the control group by lecture method whereas computer simulations were used for teaching mathematical concepts to the experimental group. Data analysis showed that in the posttest, the experimental group performed better than the control group at a 0.05 level of significance. The scores of the retention test of the experimental group were also found better than the control group. It is recommended to include computer simulations in the teaching-learning process for better comprehension of abstract concepts of mathematics.     Keywords: Achievement, Mathematical Concepts, Retention, Simulations

Doing reading comprehension needs active process in doing. The suitable teaching-learning process must achieve the objective of reading comprehension. In fact, reading skill is not easy. Lecturer should use good strategy in teaching about reading comprehension. It also happens for students that they find some hard in doing reading comprehension well. They can’t get good value for understanding the text meaning. So, the strategy is very useful to solve the difficulties in reading comprehension. This study is concerned with the reading effect about descriptive text through Metacognition strategy application. This study learns about students reading skills in descriptive text. This research is conducted based on experimental quantitative design which has two randomized subject. The population were Health Information Management students at Deli Husada Deli Tua Health Institute grade I, II and III. The random sample was taken from grade I and III as group of experimental and grade II as the control group. In every group was given pre-test and post-test in same test but the experimental group accepted the treatment of Metacognition strategy in the study. The result of this research showed that there was difference between the mean of the group of experimental and the group of control. The statistic calculation showed that t-observed (4.1) is higher than t-table (1.67) for the degree of freedom (df) 58 at the level α = 0.05 level of significance. It proves that Metacognition strategy has significantly effect on students’ reading comprehension in reading descriptive text.

The population of the study was the students of grade VIII of SMP Negeri 5 Tebing Tinggi in the academic year 2015/2016, which consisted of 9 parallel classes. Two classes were taken as the sample by applying lottery technique and each groups consisted of 30 students. The sample was divided into two groups. The class VIII-5 was experimental group and class VIII-7 was control group. The Experimental group was taught by applying questioning strategies; otherwise the control group was taught by using conventional strategy. The data of the study were obtained by objectives test. To determine the reliability of the test, KR-20 formula was used. The data calculation showed that the coefficient of reliability of the test was 0.62. It showed that the test was reliable and the reliability was substantial. The data were analyzed by applying t-test formula.

Graphic organizers are used in ELT classroom to help the students learn better. It refers to the way the students use graphic organizers in writing. The purpose of this study is to investigate the effect of graphic organizers on ELT students’ writing quality. This study was a quasi-experimental research design. The experimental group was taught by using graphic organizers. The control group was administered by using conventional strategy. The participants of the research were the second semester students of English Department, in one of the private universities in Madiun. The data were analyzed by utilizing independent t-test and one-way ANOVA based on the level of significance at .05. The result of the study shows that there is a significant difference between the mean scores of the students in the experimental and control groups. The students who are taught by using graphic organizers are better than the students who are taught using conventional strategy. The students in the experimental group perform better on writing quality in terms of content, vocabulary, and mechanics than those who do in the control group. It can be concluded that graphic organizers have a significant effect on ELT students’ writing quality. It is effective to be used in order to help the students write better. The students are successful in generating the ideas of writing and it can create a social community. We recommend for the future researchers to realize other various graphic organizer models into research.

This research is an experimental research which aims to describe the effectiveness of the methaporical thinking approach to improve the mathematical representation ability of class VIII SMPN 2 Toari. In addition, it also aims to determine how much students are engaged in the learning process when applying the methaporical thinking approach. The research subjects were divided into two groups, namely the experimental group taught using the methaporical thinking approach and the control group taught by conventional learning. The results showed that students who were taught with a methaporiical thinking approach were more active in the learning process so that the ability of representation also increased. In addition, it was found that mean of mathematical representation ability of students taught using the approach of methaporical thinking was better than students taught with conventional learning. Therefore, the approach of methaporical thinking is able to improve the mathematical representation ability of class VIII SMPN 2 Toari
