This study explored the use of concept cartoons to enhance the performance of Junior High School pupils in selected science concepts by using pre and post intervention test. Sample comprised 37 Junior High School pupils and one science teacher in Abelemkpe Junior High School in the Greater Accra Region of Ghana. Concept cartoons are instructional tools designed to generate scientific thinking among learners. Adapted to the 5E instructional model, they can be used at any stage of the learning process to facilitate effective learning of scientific concepts. Completed tests based on five selected science concepts were analyzed using the t-test inferential statistics to establish any significance difference between respondents’ mean scores of the pre and post intervention data. Results revealed that the use of concept cartoons to teach the selected science concepts enhanced the pupils’ cognitive achievement. The concept cartoons affected learners’ academic achievement in positive ways. The pupils were able to construct their own knowledge and made meaning of their everyday experiences. Results of the t-test (t (36)=8.41, p=.000), (t (36)=9.38, p=.000), (t(36)=4.85, p=.000), (t(36)=10.58, p=.000) and (t(36)=11.85, p=.000) indicated a significant difference between the mean scores of the pretest and posttest. This implied that the use of concept cartoon had a positive effect on the cognitive achievement of pupils. It is therefore, recommended that JHS integrated science teachers adopt the use of concept cartoons to teach science effectively and to increase the pupils’ motivation to learn science.

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).
