Abstract This research is motivated by the low level of learning outcomes of the students of science class XI at Bernas Binsus State Senior High School Pelalawan Regency. Therefore the experiment research is conducted by pre-test and post-test scheme to discover the effect of problem based instruction learning model by virtual laboratory media toward learning outcomes of class XI students at Bernas Binsus State Senior High School Pelalawan Regency at the subject of buffer solution. The subjects of the research are the students of class XI science in the year of 2015-2016 with two classes as samples: class XI science 3 (experiment) that consists of 28 students and class XI science 2 (control) that consists of 29 students. The research data is collected by using observation, initial data test which is homogeneitytest and final data test which are pre-test dan post-test, and documentation. To discover the effect of the implementation the learning model toward the learning outcomes, the formula of partial equilibrium (Kp) is employed. The effect differences are analyzed by t test polled varians. Analysis result of initial and final data indicates that t-counting = 2.79 and t-table = 1.67 in the significance rate of 5%. The value of t-counting > t-table that makes Ho is rejected and Ha is accepted. It indicates that there is a correlation of the implementation of Problem Based Instructionlearning model with virtual laboratory media toward learning outcomes of the students of class XI Bernas Binsus State Senior High School Pelalawan Regency at the subject of buffer solution, with the effect of 12.43 %.

AbstractThis research aimed at designing Green-Chemistry-oriented Chemistry module on Electrolyte and Nonelectrolyte Solution lesson that was valid based on validity media expert, lesson expert, teacher practicality, and student response. It was Research and Development (R&D) research that implemented Borg and Gall Development model. It was administered at the eleventh-grade students of MIPA 1 of State Senior High School 1 Kampar. The instruments of collecting the data were validity test questionnaire by the experts, teacher practicality test questionnaire, and student response questionnaire. The collected data were analyzed by using Descriptive qualitative and quantitative analysis techniques. The module could be stated appropriate, if it passed validity and practicality aspects. The validity result of chemistry module by 2 media experts and a material expert was 87.09% and it was on very valid category. Practicality test of 3 Chemistry subject teachers showed a result 87.84% that was on very practical category, and it was obtained a very positive response from 10 students, it could be seen from questionnaire result 90.78%. Based on these results, it could be identified that Green-Chemistry-oriented Chemistry module on Electrolyte and Nonelectrolyte Solution lesson was appropriate and practical to be an additional teaching material for teachers at a school.Keywords:Module, Green-Chemistry, Electrolyte and Nonelectrolyte Solution.

The present study was encouraged by the low learning outcomes of students at MAN 1 Pekanbaru that were influenced by the lack of students’ participation during learning process and caused teacher-centered learning. This study was a quasi-experimental research with Pretest-Posttest Control Group design. It aimed at investigating the effect of implementing learning model “Guided Inquiry-Based Portfolio Assessment” on students’ chemistry learning outcomes in colloid topic at XI Grade of State Islamic Senior High School 1 Pekanbaru. Afterwards, the samples of this study were students of XI Science 2 class as an experimental class and XI Science 3 as a control class taken through simple random sampling from all students of XI Science classes in academic year 2015/2016 as population. In addition, the data was collected by using tests including homogeneity test as the preliminary data in the previous materials and pretests and posttests as the last data, documentation, and observation. Then, the data were analyzed by using t-test. As the result, it was obtained that tobtained =2.880 and ttable =2.000 in significance level 5%. Therefore, it showed that tobtained ≥ ttable so that Ho was rejected and Ha was accepted which indicated that there was an effect of implementing learning model “Guided Inquiry-Based Portfolio Assessment” on students’ chemistry learning outcomes in colloid topic at XI Grade of State Islamic Senior High School 1 Pekanbaru with influence coefficient 12.5%. Key words: 1. learning model “Guided Inquiry-Based Portfolio Assessment”, learning outcomes, colloid.
