The objective of this study was to find out whether or not there is any significant differences between teaching writing the eight grade students by using e-mail exchanges and those who are not. The method of this study was quasi experimental non-equivalent control group design. The total number of population was 278 students. The sample was class VIII.1 and VIII.2 were classified into two groups, experimental and control group. The data were collected through test. The test was writing test, namely pretest and posttest, and the results were analyzed by t-test by helping SPSS (Statistical Package for the Social Sciences), the data were obtained from the pretest of the experimental group. The pretest was given before giving the treatment, and posttest after the treatment. It The writing test was about personal letter written by the students based on one of topics that they preferred. Based on the data analysis, the mean score of the posttest in the experimental group is 43.7500 and the mean in the control group is 25.9659. It means the mean score of the posttest in the experimental group is higher than the mean in the control group. The result of independent sample t-test shows that t-obtained is higher than the critical value of t-table is 16.780 > 1.664. It could be concluded that there is any significant improvement in personal letter writing between the students who are taught by using E-mail exchanges and those who are not.

Improvisational exercises is a technique which consist three steps, they are preparation, modelling, and playing, that is preparation the teacher presents exercises, the students practice (modelling), and then procedure (playing)and the it provides three main goals; (1) the students pronounciation improve, (2) proper use of grammatical structure is reinforced, (3) vocabulary practice in enhanced. With this background, this research was quasi-experimental, with non-equivalent control group design. The sample consisted of two classes of students enrolled in 2013/2014 academic year, which one group was taken to be an experimental and the other to be a control group. The data obtained through the test were analysed by using statistical analysis. In conducting the research, the researcher used improvisational exercise technique to evaluate the students’ speaking performance which covered by three components of speaking, such as: fluency, accuracy, and comprehensibility. The research findings shows thatthe use of improvisational exercise technique (presentation, modelling, and playing) in teaching speaking can improve the speaking performance of the eight year students of  SMP Negeri 2 Majene significantly after being given treatment. The mean score of experimental group in post-test and control group were significantly different. The mean score of post-test in experimental group (3.36) was higher than control group (3.00).Thus, it is recomended for all English teacher to improve the students ability in speaking.

Problem solving is a process that has been implemented in order to obtain a solution to a problem that is carried out in stages. Teamwork is the ability of individuals to work together with others and aims for members to be able to participate in the team and understand their duties. This study aims to determine the ability to solve problems and teamwork (teamwork) in children aged 10 years using puzzles. This research is an experimental study with a quasi-experimental design: non-equivalent control group design. The participants in this study were 8 children aged 10 years consisting of 5 boys and 3 girls. The data collection in this study was the acquisition of time in the preparation of puzzles. The data that has been obtained is then analyzed using the t-test (t-test). The results of this study indicate that the experimental group has faster problem solving than the control group because of the learning outcomes of teamwork.

The aim of this study was to know the effectiveness of the use of alphabet cards game as interesting tool to explain vocabularies and it make it easier to remember their meanings. This study belongs to the quasi experimental research and presents pre-test, post test and to investigate the effect of using alphabet cards game on vocabulary mastery of commercial business administration students. The participants were the students from commercial business administration students at the third semester (N=54) of State Polytechnic Bengkalis and divided into two groups. Both groups were taught vocabulary, however, the experimental group students who are exposed to alphabet cards game and the controlled group students who received conventional method. Pre-test and post-test were given to both experimental group students and controlled group students. The score of the vocabulary tests were compared through independent sample t-test. The mean value of pre-test of experimental class was 61.35, while the control class was 52.23. After learning using alphabet card games in experimental class the mean value obtained in post-test was 78.85, while in control class was 59.04.  The improved of learning outcomes can be seen from the level of significance was 0.000 and it was lower than t test 0.000<0.05.  It means that the hypothesis null is not accepted. Therefore, it can be concluded that the score of the students in learning vocabulary between the experimental group and control group was significantly different. The experimental group students who learned vocabulary using alphabet cards game had increased their vocabulary mastery.

Making connections between the representations of trigonometric functions and an interpretation of graphs of the functions are major challenges to many students. This study explores the effectiveness of the GeoGebra on grade 12 students’ success in making connections between the representations of trigonometric functions and the interpretation of graphs. A non-equivalent control-group pre-test post-test quasi-experimental design was used. The sample of the study consisted of sixty-one grade 12 students from two schools. The results showed that there was a statistically significant difference between the mean achievements of the experimental group and the control group on making connections between representations of trigonometric functions, and on analyses and interpretations of representations of trigonometric functions, in favour of the experimental group. This study extends the findings of previous studies on the effectiveness of dynamic mathematics software on students’ learning of representations and interpretation of graphs of trigonometric functions.            Keywords: GeoGebra, functions graphs, Trigonometric functions

This study tried find the students’ improvement in listening achievement after having taught by using the shadowing technique. The method used was a quasi-experimental that involved two groups, namely the control group and experimental group. The population of this study was all the tenth graders of SMA Negeri 3 Unggulan Kayuagung with a total number of 198 tenth graders. Purposive sampling method was applied to select the sample involved 72 tenth graders. In collecting the data, try out the test was used to get the desirable questions that would be used in the pretest and posttest to both groups in the control and experimental group. To verify the hypothesis, the normality and homogeneity of the data were firstly analyzed before being continued to be analyzed by using a t-test. Based on the result of data analysis in an independent sample t-test, there were some findings found. First, the mean score of a posttest (75.56) in the experimental group was higher than the pretest (69.03) in the control group. Secondly, the value of tobtained was 2.77 at the significant level of p<0.05 in two-tailed testing with df = 70, the critical value of ttable was 1.99. Since the value of tobtained was higher than ttable, the null hypothesis (Ho) was rejected and the research hypothesis was accepted. In conclusion, it showed that the shadowing technique could improve the tenth-grade students’ listening achievement at SMA Negeri 3 Unggulan Kayuagung.
