The goal of this research is gaining description on science literacy improvement of junior high school students regarding the topics of earthquake and flood as an effect of Contextual Based Learning (CBL) implementation during science instruction. Quasi-experiment serves as the method of this study with non-equivalent control group pre-test post-test design. Jigsaw cooperative learning method functions as the control treatment. Research subjects involve 52 students of grade VII in a state junior high school in Bandung Regency, West Java. Those research subjects are divided into two classes namely experiment class and control class. The instrument used to collect relevant data is science literacy test covering aspects of science content, science competence, and attitude towards science. Two independent sample t-test is applied to analyze the comparison of science literacy improvement reached between experiment and control class. The result of statistical calculation for two independent sample t-test N-gain using version 23 SPSS software shows a significant value of 0.00 < α. 0.05 for all aspects. The findings indicate that CBL implementation during science instruction within topics of earthquake and flood is proven to be valid to improve students’ science literacy compared to jigsaw cooperative model.

This research purposed to analyze the effect of video learning of civic education about state which was manipulated by experiment group (audio visual method use video) and control group (conventional method use teacher) to gain students knowledge. The samples of the study were fourty students in Satu Atap Lontar Junior High School who had not implemented the audio visual (video) learning method. This study applied an experimental design with pretest and posttest design. The results score of experiment group pretest means are 5.35 and posttest means are 6.2. The increase of knowledge generated from this method was 8.8%, after that, we do the paired t test and did not show any significance at all. Different results were obtained by the control group, with a pretest means are 7.65 and posttest means are 9.1. The increased of this method was 19.7%, after that, we do the paired t test and show the real significant with p<.05. The conclusion that learning by conventional methods can not be completely replaced by audio visual methods. However, they can be collaborated into effective learning methods to increase students knowledge of state in rural schools, especially Satu Atap Lontar Junior High School.

Background: Indonesia is a tropical country rich in various vegetables and fruits which are necessary for health because they contain lots of vitamins, minerals and fibers. However, Indonesian children and teenagers do not often pay attention to balanced nutrition, particularly vegetables and fruits. They even tend to choose fast food which may lead to occurrence of obesity. Prevalence of obesity among teenagers becomes an important issue because it persists to adulthood. Impact of obesity is a threat to public health and needs serious attention. Considering the important role of vegetables and fruits for health especially among obese teenagers, awareness on the necessity of consuming those needs to be made and built through nutrition counseling.Objective: The objective of the study was to identify the effects of counseling on the advantages of vegetables and fruits consumption to nutrient intake (energy, protein, fat, carbohydrate and fiber) among obese teenage students of junior high school at Palembang Municipality.Method: The study was quantitative with quasi experimental design. Subject of the study were obese teenage students of junior high school at Palembang Municipality aged 12 – 15 years old. There were 72 respondents of intervention group and 72 respondents of control group. Samples were taken using non random sampling technique. T-test was used to find out effects of counseling to consumption of vegetables and fruits and nutrient intake before and after intervention.Result: Delta average value of fruit consumption and nutrient intake (energy, fat, carbohydrate, and fiber) based on t-test analysis showed significant difference in both groups with p<0.05. Meanwhile, delta average value of vegetable consumption and nutrient intake (protein) did not show significant relationship (p>0.05).Conclusion: Counseling on the advantages of vegetables and fruits affect consumption of fruits and nutrient intake (energy, fat, carbohydrate and fiber).

The objective of the study is to investigate the effectiveness of SQ3R strategy on students’ reading comprehension at State Junior High School 2 of Bululawang. The study used quantitative method with quasi-experimental design because there were two different groups for the samples namely experimental and control group and also the researcher gave different treatment for both experimental and control group. For experimental group the researcher taught by using SQ3R strategy while for control group the researcher taught by using skimming-scanning strategy. The researcher took VII A as control group and VIID as experimental group by using flipping coin. The instrument of this study was a reading test conducted twice as a pretest and post-test and the supporting instrument was a questionnaire. The results of hypothesis test showed that significance value was 0.000. So, there was a significance effect of SQ3R strategy on students’ reading comprehension at State Junior High School 2 of Bululawang. In other words, SQ3R strategy was effective and applicable for seventh grade students at State Junior High School 2 of Bululawang specifically on descriptivetext. Indeed, this strategy is recommended for teachers and students in learning English especially in reading skill to increase the students’ reading comprehension and stimulate the students’ activeness during teaching-learning process.

Objectives: The increased humeral retroversion on the dominant side in throwing athletes is thought to result from repetitive throwing motion. In the previous studies, the degree of increased humeral retroversion was various, suggesting that other factors may affect humeral retroversion. Little Leaguer’s shoulder, which is rotational stress fracture of the proximal humeral epiphyseal plate, may change humeral retroversion. The purpose of this study was to investigate effect of Little Leaguer’s shoulder on humeral retroversion. Methods: Ten high-school baseball players (average, 16.6 years; range, 16 to 18 years), who had had Little Leaguer’s shoulder during elementary or junior high schools (average, 12.6 years; range, 11 to 15 years), were enrolled in the study. As a control group, 22 high-school baseball players (average, 16.9 years; range, 16 to 18 years), who have never had shoulder or elbow pain, were included in this study. Humeral retroversion was ultrasonographically measured on the dominant and non-dominant sides. Humeral retroversion was compared between dominant and non-dominant shoulders with paired t-test. Side-to-side difference in humeral retroversion was compared between Little Leaguer’s shoulders and control group with unpaired t-test. Results: Humeral retroversion was significantly greater on the dominant side than on the non-dominant side in both Little Leaguer’s shoulder (Dominant, 104°±8°; Non-dominant, 84°±12°; P < .001) and control groups (Dominant, 91°±13°; Non-dominant, 81°±10°; P < .001). The side-to-side difference in humeral retroversion in Little Leaguer’s shoulder group (20°±10°) was significantly greater than that in control group (10°±10°, P = .02). Conclusion: Humeral retroversion was increased with repetitive throwing motion without any symptom in the shoulder and elbow joint. Additional increase in humeral retroversion was made when the players had had Little Leaguer’s shoulder in elementary or junior high school.
