THE INFLUENCE OF PROBLEM BASED LEARNING MODEL TOWARD SAINS LITERACY SKILL OF STUDENT ON REACTION RATE MATERIALS
No full textThis study was aimed to know the effect of problem-based learning model on the ability of students scientific literacy in reaction rate material. Scientific literacy that is examined in this study only on competency dimension of science. This research was conducted at SMAN 8 South TangerangCity. The method used was quasi-experimental with nonequivalent control group design. The sample was taken byusing purposive sampling technique. The data was taken by using an essay test of scientific literacy ability in competency dimension of science. The analysis of data used is t-test that obtained tcountvalue totaled 8.27 and ttable on significant level0.05is 1.99, so that thetcount>ttable. So we can concludethat Ho was refuse. This indicatesthatthe application of problem-based learning model provides a significant impact on the ability of students scientific literacy in reaction rate material.

THE DEVELOPMENT OF BIOLOGY PRACTICE IN HIGH SCHOOL SCHOOL BASED ON ETHNOBIOLOGY
No full textLocal knowledge of the Dayak Ngaju community in Gunung Mas regency, Central Kalimantan there were believed that many species of plants, animals and their surroundingscan be used as an indicator of a particular environtment. The local people experience is one example of local knowledge which needs to be studied scientifically through ethnobiology.Study of ethnobiology was confined to the local community\u27s knowledge about the medicinal plants (ethnobotany), local community knowledge about the utilization of existed nearby animals (ethnozoology) and knowledge of the local community in ecosystems around their living quarters (ethnoecology). Afterwards these studies was arranged into biology practical work material. The purposesof the studyare(1) to study theethnobiology of local knowledge of DayakNgajucommunitiesinGunung Mas regency, (2) to inventoryandidentifyseveral species that areusedin foodstuffs, pharmaceuticals, industry and utilization of the environment for the practical work in high school. This should be well documented and to be taught to the next generations to avoid the extinction of local knowledges.Integratingthe materialethnobiology into learningbiology is one of the best ways to deliverlocalknowledge in formal education. It was suggested to teach ethnobiology inbiology practical work, especially inhigh school who have forest environment as characteristic oftheir territory since ethnobiological material was very important.

THE RELATIONSHIP BETWEEN SELF-CONFIDENCE AND STUDENTS PERFORMANCE IN BIOLOGY LAB EXCERCISE
No full textBiology lab exercise are an important aspect on learning process. However, the outcome of the lab activity might not come as the curriculum goals expected. It is due to several reasons. This paper try to measure the relationship between students’ character and students’ performance in Biology lab exercise. This study used self-confidence as a proxy of students’ character. A unique Indonesian high school datasets and simple regression analysis were used for this research. Evidence shows that pupils’ self-confidence 3% among other variables that determine students’ performance and it has positive but insignificant impacts on students performance. The evidence demonstrates there is a weak relationship between self-confidence and students performance in lab practice. Keyword: self confidence; performance of students; Biology practic
ENVIRONMENTAL LITERACY ON GARBAGE MANAGEMENT AND GREENING ACTIVITY OF HIGH SCHOOL STUDENTS IN GREEN SCHOOL AND NON-GREEN SCHOOL
No full textThis survey research was conducted to understand the difference and level of environmental awareness and knowledge on solid waste management dan vegetation re-planting of students from Eco-School (adiwiyata) and Non Eco-School (non-adiwiyata). The number of respondents was 198 students from two high Eco-Schools (SMA N 1 Pengasih and MAN 2 Wates) and two high Non Eco-Schools (SMA N 1 Girimulyo and SMA N 1 Wates). Sample was chosen by random sampling. Students were given a set of questionnaires, which consisted section A tested students awareness and section B tested students knowledge. The data were statistically analysed using Mann-Whitney and descriptive statistics. The results of Mann-Whitney showed that there are significant difference on environmental awareness and knowledge between student taught in Eco-School and student taught in Non Eco-School (Sig.< 0,05). Meanwhile, the level of environmental awareness and knowledge between student taught in Eco-School and student taught in Non Eco-School are in the same level. The level of environmental awareness between student Eco-School and Non Eco-School is in the same low level and the level of environmental knowledge between student Eco-School and Non Eco-School is in the same low level.
