This research was aimed: 1) to know the result of environment studying in school which do not apply adiwiyata program, 2) to know the result of environment studying in school which apply adiwiyata program, and 3) to analyze the significance of environment studying result between school which apply adiwiyata program and not. This research applied quantified approach. The kind of this research was non-experimental, with ex post facto design. The form of applied-design in this research was causal comparative studies. The result of the research showed: 1) the student’s result in studying environment materials on non-adiwiyata school was in middle category, 2) the student’s result in studying environment materials on adiwiyata school was in high category, and 3) there was significant differences between the student’s result in studying environment materials at class XI on adiwiyata and non-adiwiyata school with 95% trusted-score.

This pre-experimental research aimed to determine effectiveness of project-based learning model implementation towards problem solving ability of students on biothecnology subject matter. This research hypotesized that implementation of project-based learning model is effective towards problem solving ability of students on biotechnology subject matter. Average score of problem solving ability obtained at pretest was 29.46, while at posttest was 69.25. Effectiveness of project-based learning model implementation was assessed with inferential statistical analysis using SPSS 18 and the results was significant. (2-tailed) 0.000 <α = 0.05, which means that H0 rejected and H1 accepted, thus indicating that the hypothesis accepted. As for assessing effectiveness level, an N-gain test was used, which showed that the level of effectiveness of project-based learning model implementation was 37 (92.5%) of total students obtained N-gain in the middle and / or high range category. Based on this results, it can be concluded that the project-based learning model implementation is effective towards the problem solving ability of students on Biotechnology subject matter.

This study aims to see students learning outcomes in class VIII A SMPN 13 Manokwari Academic Year 2017/2018 on the Human Digestive System material by applying the model of Problem Based Learning PBL). Classroom action research (CAR) was conducted in two cycles, each cycle consisting of four stages: 1) planning, 2) implementation, 3)observation, 4) reflection, involving 24 students. Data collection is done through observation sheets, interviews, documentary coverage and tests. The results of this study indicate that the students learning outcomes in Cycle I average 61.3 with 62.5% completeness and increased to 69.3 with 83.33% completeness in cycle II. This indicates that the percentage of students learning outcomes have fulfilled standard classical, 75% of KKM 60. The conclusion show that the learning process with the application of Problem Based Learnig (PBL) model can improve the learning outcomes of students class VIII A SMPN 13 Manokwari.

This research is research and development which aim to arrange and develop student worksheet for Senior High School grade XI based on guided inquiry on KTSP. Subject is students of class XI IPA2 SMA Negeri 2 Polewali. The development of this student worksheet refers to developmental model of 4-D by Thiagarajan. that included define phase, design phase, and develop phase. Fourth disseminate phase was not done. This student worksheet has already validated by validator and through limited try out, as well as revised many times by developer so that obtaining valid, effective and practical result. This research showed that: in cognitive aspect, the class completeness is 81,25 %; students activities in psychomotor and affective aspect showed positive tendency with each percentage for psychomotor is 81,25 % while for affective aspect is 91 %;commonly students gave positive responses toward used student worksheet likewise the responses of their chemistry teachers.

The purpose of this study is to describe the effectiveness of cooperative learning model Type Everyone is A Teacher Here (ETH) in learning mathematics on circumference and perimeter of twodimentional figure material in class XI SMKT Somba Opu Sungguminasa Kab. Gowa and describes learning outcomes, responses, activities, learning independence, and students' mathematical communication skills through the implementation of cooperative learning model type Everyone is A Teacher Here (ETH). This type of research is a pre-experiment research involving one class One Group) as an experimental class, with sample selection using Simple Random Sampling technique. The results showed that the implementation of cooperative learning model type Everyone is A Teacher Here (ETH) on the material and Area Width of Flat in the category well done. Implementation of ETH type of cooperative learning model on mobile material and Broadband Building in grade XI SMKT Somba Opu Sungguminasa Kab. Gowa is effectively reviewed from aspects of learning outcomes, learning activities, responses, mathematical communication skills and student learning independence.
