Vocabulary Achievement

This current study aims to investigate the effectiveness of Vocabulary Self-collection Strategy (henceforth VSS) on the students’ reading and vocabulary achievement. The quasi-experimental research was applied and the instruments were pretest-posttest. The independent variable of this study was VSS, while the dependents were reading skill and vocabulary mastery. To collect the data, pretest-posttest was assigned. The test for both reading skill and vocabulary mastery were validated through expert judgment and content validity. Moreover, the reliability of the instruments was measured using inter-rater reliability. The data were analyzed using parametric statistical technique of T-Test and MANOVA test using SPSS 22. Computer program. The findings of this study reveal that VSS had a significant effect toward students’ reading skill and vocabulary mastery. It was indicated by the significant value of T-Test for each reading skill and vocabulary mastery which were lower than 0.05. VSS and Lecturing-practice Strategy had different capability in influencing students’ reading skill and vocabulary mastery scores simultaneously. Also, it was indicated by the significant value of Pillar’s trace, Wilka’s Lambda, Hotellings Trace and Roy’s Largest Root tests are 0.004 which was lower than 0.05. Therefore, all of the hypothesis are accepted.

Breastfeeding is very important in Growth and development of children both physically and mentally optimally and improve children's intelligence, and prevent children from diseases such as diarrhea, pneumonia and malnutrition which are common causes of death in children under 5 years. In breastfeeding, many factors influence, one of which is giving with loving touch baby massage. Giving with loving touch baby massage is expected to affect the frequency of breastfeeding and can increase the closeness of the child to the parents (Bonding). This research is a quasi-experimental research, namely research that aims to determine the effect that will arise after being given treatment, namely baby massage. The population in this study were 30 children under five in Domas Village, Gresik Regency. The independent variable in this study was loving touch baby massage, the dependent variable was the frequency of breastfeeding. The statistical test used was the Paired Sample T-Test. The results of this study can be concluded that there is an effect of baby massage on the frequency of breastfeeding and has a frequency of breastfeeding 7 times - 10 times / day greater than babies who are not done loving touch baby massage.

The objective of this study is to measure whether there is or not significant effect of teaching reading by utilizing Hot Potatoes software toward students’ reading comprehension of descriptive text. The variables used were the teaching treatment of Hot Potatoes Software as the independent variable and the students’ reading comprehension of Descriptive Text as dependent variable. Then, the research designed was Quasi-experimental design and the presentation of data used was quantitative. The data were obtained from the eleventh grade, of which 28 students were taken as sample. The students are divided into two groups; experiment group consisted of 12 students and control group consists of 16 students. To get the data, the pre-test and post-test were applied and then analyzed using t-test formula. The researcher had concluded that there is Significant effect of Hot Potatoes Software toward the students’ reading comprehension achievement. The result showed that mean of students’ post-test was increased. It is proved by the t-test (8.54) which is higher than t-table (2.05) at level of significance 5%. It means that the alternative hypothesis was accepted and it proved that Hot Potatoes Software had significant effect toward students’ reading comprehension of Descriptive Text

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
