Using group to develop students’ achievement in learning English grammar: An experimental study At eight grade of the SMP Assalaam Bandung

This study emerges from empirical phenomenon among students who lack of English grammar. Seeing such a phenomenon, the writer was interesting to investigate how group task influences the students’ English grammar. This research aim to know how significant group task influence students’ English Grammar. In specific, the research aim to: To identify students’ achievement in English Grammar after being exposed with group task, to identify students’ achievement in English Grammar after being exposed with conventional technique, to find out the influence for the student’s achievement in English Grammar after being exposed with group task and conventional technique. Generally, the research was approached by quantitative method. The technique of collecting data was an achievement test. The total population in this research was 160 students, in which the sample was represented by 64 students. Therefore data analysis used statistic calculation. In this research the writer used an experimental method. The technique of collecting data with grammar test was divided two classes, the experiment class (using the group task technique) and control group (using conventional method). To obtain the data, pre-test and post-test result were collected. The writer counted mean, standard deviation, t-test, and hypothesis testing in analyzing the data. Data analysis shows that the student’s English grammar using group task technique in experimental group have higher score than those of using conventional teaching technique. It means that the experimental group is more effective than control group in increasing English grammar. From the testing on hypothesis, it can be concluded that teaching English grammar through group task technique has a significant influence. Based on the result of testing hypothesis it shows that t count = 5.45 and t table = 1.999 or t count is more than t table. It means that null hypothesis (Ho) is rejected, which means that alternative hypothesis (Ha) is accepted. Therefore, there is a significant difference between the students mastering of English grammar taught by using group task and the students mastering of English grammar using a without group task
