<![CDATA[Blended learning is mixed learning, namely online and face-to-face learning. Because it is still during the Covid-19 pandemic, learning is currently still being carried out online. To support the online learning process, the Zoom Cloud Meeting application is used. The learning process can also be carried out offline but in accordance with the protocol from the government. This study aims to determine student learning outcomes after being given treatment can exceed the KKM value. The study used an experiment with a one shoot case study research design. This research was conducted at SMA Negeri 1 Tutuyan for the academic year 2020/2021 with 29 students in class X MIA 1. The data collection technique was a posttest and the instrument used to measure learning outcomes was a multiple choice test. The results of this study used the t-test one sample t-test with the results of ttable 1.701 and tcount 28.8476 with a significant level of 5% and therefore ttable was smaller than tcount. Thus, it means that H1 is accepted and H0 is rejected. So it was concluded that student learning outcomes after being given treatment can increase and exceed the KKM value.]]>

<![CDATA[This research is an experimental research with Mastery Learning model. This study aims to determine the effect of the Mastery Learning model on student learning outcomes on the mole concept material. This research was conducted in class X SMA Negeri 1 Remboken with a sample of 57 people. The research design used is the post-test-only control group design experimental method. The experimental class uses a complete learning model and the control class uses a conventional learning model. Analysis of hypothesis testing using t-test with a significant level = 0.05, because with a two-way test then the value of a/2 = 0.025. The test results obtained show that the results of t arithmetic > t table or 9.02 > 2.05, thus H0 is rejected and H1 is accepted, this indicates that there is a significant difference between the average value (post-test) of the experimental group and the experimental group. control group experiment. So it can be concluded that there is a difference in the average learning outcomes of students who are taught the mastery learning model with the learning outcomes of students who are taught conventional learning on the mole concept material.]]>

<![CDATA[The demonstration method is a method that can make students' attention more focused on what is being taught so that students are more active and do not feel bored in learning. This study aims to see the effect of the demonstration method on student chemistry learning outcomes on colloidal system material at SMA Negeri 1 Tutuyan in the 2020/2021 academic year. This research is a pre-experimental research with one group pretest-posttest design. The population in the study were all students of class XI IPA and the sample taken was class XI IPA MIA 1, totaling 30 people. Testing the hypothesis using the t-test formula at the significant level = 0.05. Based on the data analysis, the value of tcount = 23.90 and ttable = 2.045. The value of tcount > ttable then H1 is accepted and H0 is rejected, so it can be concluded that H1 is accepted, which means there is a significant difference between student learning outcomes on colloidal system material before and after using the demonstration method because there are differences. student learning outcomes. To find out how much the effectiveness of using the demonstration method is continued with the N-Gain test and obtained is 0.76 with high criteria.]]>

<![CDATA[The purpose of this study was to find out how much misconception analysis is on the material of electrolyte and non-electrolyte solutions for class X students at SMA Kristen Eben Haezer, West Halmahera, the research method used in this study is a qualitative descriptive approach. The results of this study indicate that there are two stages of testing, namely: (1. Validity test is Valid, meaning that the ability of the item to support the construct in the instrument. To test the validity of the construct can be done by asking from an expert (expert judgment). After construct testing is completed, it is continued with After being tabulated, the validity test is carried out with the help of Excel 2013. (2. Reliability Test is the reliability of the instrument is the level of stability of the instrument when used when and by anyone so that it will tend to produce the same or almost the same data as before. This means that the instrument used is the same as before. that will be used in this study will give the same results even though the reliability test is repeated using the Rash Model analysis with the help of Winsteps.]]>

<![CDATA[This research is an experimental study of Problem Based Learning model. This study aims to determine the effect of the Problem Based Learning learning model on student learning outcomes on the mole concept material. This research was conducted in class X SMA Negeri 1 Remboken with a total sample of 64 people. The research design used is an experimental method with a quantitative approach and the type of research used is a quasi-experimental research (Quasi Experimental design). The experimental class uses the Problem Based Learning model and the control class uses the conventional learning model. Analysis of hypothesis testing using t-test with a significant level of = 0.05 because, two-way test then the value of a/2 = 0.025. The test results obtained show that the results of tcount > ttable or 9.653 > 1.99897, thus H0 is rejected and H1 is accepted, this indicates that there is a significant difference between the average posttest scores of the experimental group and the control group. So it can be concluded that there is a difference between student learning outcomes using Problem Based Learning) and student learning outcomes using conventional learning models on the mole concept material.]]>

<![CDATA[This study aims to determine the relationship between the online learning process during the Covid-19 pandemic and the science learning achievement of class X SMA Negeri 2 Tondano students. The online learning process is a teaching and learning process that is carried out online and interactively by utilizing information and communication technology, such as computer media with the internet as the delivery and recipient of the material. The research design used is correlational, with data collection techniques in the form of questions (statements) questionnaires and the average value of report cards using 20 students as samples. Tests carried out to prove the hypothesis were carried out by simple linear regression analysis, Pearson Product Moment correlation and t-test. The results of the regression equation obtained are Y = 0.2634x + 68.519 with a correlation value of r = 0.693 in the level of strong relationship, and the results from the t-test are tcount = 4.080 and ttable = 2.100, meaning tcount > ttable at = 0,05, the correlation between variables X and Y is significant, meaning that there is a strong and significant relationship between the online learning process during the Covid-19 pandemic and the science learning achievement of class X SMA Negeri 2 Tondano students.]]>

<![CDATA[The purpose of this study was to develop a Learning Video for Chemical Bonding Materials with the Addie Model as Learning Support during the Covid-19 Pandemic. This research is research and development (Research and Development). This research is a research that refers to the ADDIE model (Analysis, Design, Development or Production, Implementation or Delivery and Evaluations). By following the fifth stage of the ADDIE model, because this is a Video Development research, this research only reaches the fourth stage, namely the Implementation stage. Data collection techniques in this study used a Validation Questionnaire (validation of media experts and validation of material experts) and Student Response Questionnaires. The results of the first material expert validation are included in the "very feasible" criteria with a percentage of 80%. The results from the second validation questionnaire are included in the 'very feasible' criteria with a percentage of 100%, the results from the first media expert validation questionnaire with the 'very feasible' criteria with a percentage of 95.12%, the results from the second validation questionnaire are included in the 'very feasible' criteria with a percentage 86.66% and the results of the student response questionnaires are included in the "very feasible" criteria with a percentage of 90%. Learning videos are declared very suitable for use in the learning process.]]>
