In learning English, the students often make some problems while building a recount text. One of the problems causing it is that the teacher might use the old teaching method. This research aimed to observe the effect of grammar-focused writing instruction on the tenth-grade students' writing recount text at one of the Senior High School State at Kabupaten Tangerang. The research method used in this research was a quantitative method with a quasi-experimental design by using a non-equivalent control group design. The population of this research was 460 tenth grade students. The sample of this research was taken from two classes that were chosen by using Simple Random Sampling. There were X IPS 4 as the controlled class and X IPS 5 as the experimental class. The normality test result showed that the data is normally distributed, and the homogeneity test result showed that the variants belong to a homogeneous population. The analysis results of post-test by using t-test (The Pooled Variance Model T-test) were obtained data that t-count = 4,37 and t-table = 1,99 with significant level ɑ = 5% or 0,05. From the post-test calculation result, H0 is rejected, and H1 is accepted. It can be concluded that there is a significant effect of students’ writing recount text between students in the experimental class who were taught by using grammar-focused writing instruction and students in the controlled class who were taught by using the conventional method.

Abstract - Physics learning is still considered as learning that is less attractive to some students. Students’ lack of learning interest in physics learning makes their achievement low.  The purpose of this study was to develop a learning media of True or False Physics Fun Game Card, so as to make the students interested in learning physics which could increase students' interest and learning achievement. The kind of the card game "True or False Physics Fun Game Card" was developed from a 41 card game which was modified as needed. In True or False Physics Fun Game Card, there were 50 true and false statements. Moreover, there were also points of 10-25 based on the level of difficulty of the statements. The statements made based on the Hydrostatic Law, the Relating Vessel, and the Archimedes Law. The True or False Physics Fun Game Card was developed by using the ADDIE development model which consists of 5 development steps, such as analyzing, designing, development, implementation, and evaluation. This study was tested on 12 samples of the Physics students of Universitas Kristen Satya Wacana. The data obtained were processed qualitatively and quantitatively. Based on the results of this study, it was found that 93.75% of students responded positively toward the learning media “True or False Physics Fun Game Card” and the average value of the students' post-test results was 72.67. The 10 samples from a total of 12 test samples obtained the post-test result; 65, so as the percentage of the successful comprehension sample was 83.33%. This study contributed to increasing kinds of learning media and improving students' learning achievement, especially in physics learning.
