This research is entitled “Using graphic organizer strategy in teaching writing on narrative paragraph (experimental research). Writing is a very important subject that should be learned by English learners. The students should be able to express their ideas and opinion either in the form of a sentence or paragraph. However, the researcher found that many students at the Second Grade Students of SMP Negeri 1 Tanah Luas could not express their ideas and develop into the paragraph. Hence, the appropriate strategy of teaching and learning is very important to help students master writing skills. This research aims to know the effect of achievement between the students who are taught writing by using graphic organizers from those taught writing in the narrative by using traditional methods. This research was experimental research and used a quasi-experimental design. The samples chosen in this research were the whole students of class VIII2 and VIII4 of SMPN 1 Tanah Luas. Class VIII2 consisted of 25 students was chosen as experimental group and class VIII4 consisted of 24 students was chosen as control group. This research was conducted in three phrases; there were pre-test, treatments and post-test. The data collection technique used in this research was test. The tests were pre-test and post-test. The researcher gave pre-test before giving treatment and post-test after giving treatment. The treatment was conducted in three meetings. The data was analyzed by using t-test formula. The research result and the hypothesis authentication found by using t-test formula in significant level 5% or α = 0.05 were obtained that ttest > ttable. The ttest found in this research was 3.91. Meanwhile, ttable was gotten from the list of distribution value with degree of freedom = 47, because the data not in the table, the researcher used interpolation approach and obtained = 1.67. So >  = 3.91 > 1.67. It meant that Ha was accepted and Ho was rejected. So, graphic organizer strategy significantly affects the students’ ability in mastering writing.   Kata Kunci: graphic organizer strategy, teaching and learning, writing narrative paragraph

Mathematical logical intelligence is one of the skills that are needed in the 21st century related to mathematical problem-solving skills. The importance of this skill is not in line with the facts on the ground, where students are still weak in counting and using logic in problem solving. The purpose of this research is to improve students’ mathematical logical intelligence through the online-based integration of local wisdom of Sulapa Eppa Walasuji. Sulapa Eppa Walasuji is one of the Bugis-Makassar local wisdoms with a unique pattern, appropriate to be used as a medium for learning transformation of geometry. Through the integration of local wisdom, Sulapa Eppa Walasuji can create contextual mathematics learning, so that students can easily understand the material by connecting real-life concepts. This research includes experimental research with a quasi-experimental design of the nonequivalent control group design type. The research instrument used was a mathematical logical intelligence test consisting of five essay questions. The data analysis used is descriptive statistics with gain score and effect size testing. The results showed that the mathematical logical intelligence of experimental class students increased by 43.16 with the effective contribution of the r effect size being 0.910. This indicates that the online-based integration of Sulapa Eppa Walasuji can improve students’ mathematical logical intelligence.

The Aim of this research were to figure out the learning concept comprehension of students at class X at MAN Salidoin the academic year of 2016/2017 through Cooperative Studying Model Lottery Card Type (Arisan's Card). This was a quasi experimental research with Randomized Control Group OnlyDesign.The population of this research was of students at class X at MAN Salidoin the academic year of 2016/2017. Then, found that students as the experimental class and the control class. To get the class sample test done first then normality, its homogeneity and similarity in average for all classes of the population. After all the class known to normal, homogenous and have the same average then conducted the election of class sample randomly. Before testing the hypotheses, firstly applied the normality test and homogenety test to the sample. Then, tested the hypotheses by applying t-test formula. He got that test t (1,838) > tabel t (1,645) with 0,05 degree of freedom and with 95 % level of credence. Then he concluded that null hypothesis (H0) and the alternative hypothesis (H1) is accepted. So, the ability of the students in understanding Math Concept is higher through the Cooperative Studying Model Lottery Card Type (Arisan's Card) than the students taught through conventional learning.Keywords: Understanding on mathematic concept’s ability, learning model of cooperative (Lottery card).
