<![CDATA[This research to see the side-effect of using virtual simulation media PhET (Physics Education Technology) laboratory on student learning towards in molecular geometry at MAN 1 Bitung. PhET is a form of virtual laboratory simulation with observation or experimental activities using software conducted by a computer or mobile phone. This research was a Pretest-Postest Control Group design with a 10th grade Mathematics and Natural Sciences students which is divided two groups they are, the control group and experimental group of 15 students each. The tests carried out to prove the hypothesis were carried out by t-test with the results of ttable = 2.04 and the value of tcount = 2.59. In this case tcount > ttable then, H1 accepted i.e. the average value of the experimental group learning result, morehigher than the control group. The results showed that, the PhET virtual laboratory simulation has a side-effect to students learning results. to measuring how much the side-effect is that, the result of simple with the results of the regression equation is regression had also won three other that is Y=0.6542x 27.26 that indicates who had a positive effect with a correlation as 0.72 correlation in the rate of the strong relationship and value of the coefficient of determination as much as 0,521 or Influental as much as 52,1℅.]]>

<![CDATA[This study aims to improve student chemistry learning outcomes by applying the peer-led team learning model. This research design uses Classroom Action Research (CAR) which is divided into two cycles. With four stages, namely planning, action, observation and reflection. This research was carried out at SMA Negeri 1 Tagulandang in class X Science 1, totaling 31 students. This research is only focused on the material of electrolyte and nonelectrolyte solutions. In this study using instruments such as observation sheets, test questions and questionnaires. From the research that has been carried out, it is found that 77.41% of students have successfully met the Minimum Completeness Criteria (KKM) which was continued in the second cycle and obtained an average score of 77.58. From the results of student questionnaires and the results of observations given to students through peer-led team learning, students responded well. This shows that the peer-led team learning model has a positive impact on the learning process.]]>

<![CDATA[Guided inquiry learning model is a student centered learning model, namely stundents formulate problems, design experiments, collect and analyze data to make their own decision. In the study the guided inquiry learning model combined with iteractive multimedia, interactive multimedia is a fun and learning medium that supports educational development and plays an important role in chemical learnig activities which are still abstract in nature. This study aims to determine how the cognitive abilities of students after learning with guided inquiry assisted by interactive multimedia at SMA Negeri 1 kakas in the 2019/2020 school year. The population in this study was class XI IPA and the sample taken was class XI IPA 1 with a total of 25 students. The research instrument used was a test on students at the end of the lesson. The instrument in this study was a test of students cognitive abilities. Based on data analysis,in the buffer solution material there were 5 out of 25 students who did not reach the KKM standard and on the colloid system material there were 3 out of 25 students who did not reach the KKM standard]]>

<![CDATA[The purpose of this study was to determine the difference in the average student learning outcomes of classes taught with the jigsaw cooperative learning model and the average learning outcomes of conventional models. This research is a quantitative study using a non-equivalent control group design. The population in this study were all students of class XI MIPA SMA Negeri 6 North Halmahera, the sample consisted of 2 classes, namely XI MIPA 3 as the control class and XI MIPA 4 as the experimental class. Research data obtained in the form of the difference in the average value of the pretest and posttest, the experimental class of 29.7, and the difference in the average value of the pretest and posttest of the control class of 17.95. After being tested through the t-test, the results obtained between the control class and the experimental class were significant, namely = 2,024 Thus, it can be concluded that there is a difference in the average learning outcomes of classes that are applied using the jigsaw type of cooperative learning model with classes that use conventional models.]]>

<![CDATA[The purpose of this research to see is there are differences in student chemistry learning outcomes on buffer solution material on the use of video media with PowerPoint in online learning. The design used in this research is Pretest-Posttest Control Group Design. This research was conducted at SMA N 1 Kotamobagu with class XI MIA A as experimental class 1 (video media) and class XI MIA B (media PowerPoint) as experimental class 2. Normality testing using the Liliefors test showed that the data for both classes were normally distributed, and homogeneity testing using the similarity test of variance showed both classes were homogeneous. Hypothesis testing using two-way Independent Sample T-test with acceptance criteria H0 is -ttable<tcount<+ttable. It is obtained that tcount = -2.09 and ttable = 1.68 which means tcount is in the rejection region of H0, so hypothesis H0 is rejected and H1 is accepted. Therefore, it can be concluded that there are differences in student learning outcomes when using video media using PowerPoint media.]]>

<![CDATA[This research aims to determine the application of problem based learning (PBL) learning models on acid-base material for class XI science at SMA Negeri 1 Tenga. This research was conducted in class XI SMA Negeri 1 Tenga with a sample of 25 people. The research design used was the post-test-only control group design experimental method. The experimental class uses a problem based learning (PBL) model and the control class uses conventional learning. Analysis of hypothesis testing using t-test with a significant level of = 0.05 and success (dk) = 48. The test results obtained show that the results of tcount > ttable or 3.62 > 2.010, thus H0 is rejected and Ha is accepted, and the average the average student learning outcomes of the experimental class were 81.92, which was greater than the learning outcomes of the control class was 72.96. This shows that there is a significant difference between the average score (post-test) of the experimental group and the control group. So it can be concluded that there is a difference in the average learning outcomes of students who use the problem based learning (PBL) learning model with the learning outcomes of students who use conventional learning on acid-base materials.]]>
