The learning process of physics at school, the topics is sometime less relatedto the existing dailylifephenomenon.This condition causes low improvement of students' cognitive learning result. In this case, it was a necessary to apply a learning model to improve student learning result by applying phenomenon based learning model (PhenoBL). Quasi experiment in the form of nonequivalent control group design as the model of the research. The instrument to collect data used test of student cognitive at pretest and posttest, respectively. The Data was analyzed by descriptive and inferential analysis. The results of descriptive analysis show the average absorption rate of experiment class is 71.05% and control class is 63.33% which both classes are in a good category. In the paired sample t-test results stated an increasing of students cognitive learning outcomes from pretest to posttest. This can also be seen from the inferential analysis in that means there was a significant differences between experimental class and kontrol class. Thus, it can be concluded that the use of PhenoBL model can improve student learning outcomes of class XI MIPA SMA Negeri 5 Pekanbaru on optical material.

AbstractThis study aims to examine the effect of the application of the Jurisprudential Inquiry learning model to students' ability to argue. The research approach uses a quantitative approach with the Quasi Experiment method with The Pretest-Posttest Control Group Design. The study population was all grade X students in SMA Dua May. The sample was students of class X IPS 1 and X IPS 2, each of which numbered 32, the samples were taken by purposive sampling. The data collected was analyzed using descriptive analysis and inferential statistics using the independent sample t-test. Based on the results of data analysis, there are significant differences in the ability to argue between groups of students who learn to use the Jurisprudential Inquiry Learning Model and groups of students who learn by using the Conventional Learning Model. Where is t-count> t-table (10,639> 1,697). Jurisprudential Inquiry learning model influences 23.14% in the experimental class on the ability to argue students. Thus the Jurisprudential Inquiry learning model has a positive effect on students' ability to argue. Keywords: Learning Model, Jurisprudential Inquiry, Ability to Argue.

The learning outcomes of class X SMA PGRI METRO students based on the Pre-survey results are still many who have not met the Minimum Completion Criteria (KKM) ≥ 65. In the learning process students are less active to ask questions and less accustomed to collaborating with other friends. One alternative learning is to use an advanced expository type organizer learning model. the advanced organizer type expository learning model is a learning model that directs students to the material they are going to learn by recalling concepts related to the previous material so that students are able to discover new knowledge by expanding the understanding of the basic concepts of students. So the purpose of this study was to determine the effect of using an expository type advanced organizer learning model on the learning outcomes of class X SMAPGRI Metro. This study uses a QuasiExperimental Design research design. The quasi-experimental design used in this study is Nonequivalent Control Group Design. The data obtained were analyzed descriptively statistically. The subjects of this study were the eleventh grade students of SMAPGRI Metro which numbered 26 students. The results showed that t count> t table is 6.802> 2.056 so that it rejects the null hypothesis (H_0). Based on the results of the study it can be concluded that: the advance organizer type expository learning model has an influence on student learning outcomes.

 This research aimed to determine the differences in the improvement of students' physics learning independence through the application of the Team Assisted Individualization (TAI) learning model. This type of research used a quasi-experimental design with a non-equivalent control group design. The research sample was determined from the population of class XI IPA students of SMAN 1 Pekanbaru, based on the results of the normality and homogeneity tests of the population. Classes that were declared normal and homogeneous, two classes were randomly selected as the control class (36 students) and the experimental class (36 students). The data collection instrument used a student learning independence questionnaire for pre-test and post-test. Data were analyzed using descriptive and inferential analysis. The results of the descriptive analysis obtained the independent learning average of the experimental class was 2.71 with the high category and the control class 2.47 with the low category. The results of the inferential analysis show that there are significant differences in student learning independence before and after learning by applying the TAI learning model. Therefore, the use of the TAI learning model can improve the learning independence of class XI IPA students of SMAN 1 Pekanbaru on the material of optical instruments.

This research aim to examine the effect of multimedia assisted inquiry training learning model for students physic concept mastery. This type of research is quasi experiment with non-equivalent control group design. The research population was all students of XI MIA MAN 2 Mataram with a purposive sampling technique. The XI MIA 4 class was chosen as the experimental class and the XI MIA 3 class as the control class. hypothesis testing using independent t-test with 5% of significance level. Hypothesis testing yielded the concept mastery t count is 3.20 higher than the t table which has a value of 1.99. Based on the provisions, Ho is rejected and it is concluded that there are differences in mastery of physics concepts due to the practice of multimedia assisted inquiry training learning model. It means that there is a better increase of concepts mastery in the experimental class than the control class. This result can be proved by the N-gain test, where there is an increase of 53.92% in the medium category for concept mastery in the experimental class greater than the control class with an increase of 41.92% in the medium category.
