The aim of this research is to know the effectivenessproblem based learning model (PBL) using student worksheet on learning outcomes and students’critical thinking skills on the teaching Reaction Rate. The population in this research was grade 11th of SMA Negeri 6 Medan. Classes sample was taken by random sampling, and two classes were selected as a sample. Those two classes will be taught with Problem Based Learning model, the difference is the first class will be used students worksheets and the other class is not. The instrumentto conduct this researchwas by test and non-test. Based on parametric statistical test, the result of pretest, postest, and students’ critical thinking skills data from those two classes have a normal distribution and homogeny. Hypothesis was tested by using one tailed test with significant level ( ) =0,05. The data from hypothesis testing learning outcomes is tcal ttable (3,101 1,669), means Hois rejected and Ha is accepted. Hypothesis testing result on students’ learning outcomes using student worksheets is higher than the non-using student worksheet. Critical thinking hypothesis test is tcal ttable (4,754 1,669), means Hois rejected and Ha is accepted. Hypothesis testing result oncritical thinking using student worksheet is higher than the non-using student worksheet. Contribution of students’ critical thinking to the ups and downs of learning outcomes on the experiment class is 81,5%.

The purpose of this study was to determine: (1) the effectiveness of Android-based learning media on student learning outcomes in thermochemical material; (2) Student responses to the use of Android-based learning media on thermochemical material; (3) The learning outcomes of students who are taught using Android-based chemistry learning media are the same as the KKM value. This research was conducted at Public High School 5 Medan with a total sample of 68 people. The research instrument consisted of standardized tests and questionnaires. The analytical techniques used are: (1) Two-party t test (Independent Samples T test); and (2) One Sample Test. From the results of this study, it was found that: (1) Anroid-based chemistry learning media was effective on student learning outcomes on thermochemical material, with a t-test of 7.063 which was greater than t-table of 2.00. Then based on the Gain Score, the t-test of 6.843 was obtained, which was greater than the t-table of 2.00; (2) Student responses "Very Interesting" with percentages of 92.27%, 93.93% and 92.12%, respectively, on the use of anroid-based learning media in thermochemical material; (3) The learning outcomes of students who are taught using android-based chemistry learning media are not the same as the KKM value, where , tcount (2.126) > ttable (2.032), means that it has a positive effect on KKM

: This study aims to determine the effect of the Stad Type Cooperative learning model assisted by video media on student learning outcomes on reaction rate material in high school. This research was conducted with a quasi-experimental method of two group pretes-posttes design. The sampling technique used random sampling technique. The research sample consisted of two classes, namely XI-IPA1 and XI-IPA2 classes, each consisting of 31 students. Class XI-IPA1 was the experimental class taught using the stad type cooperative learning model. While class XI-IPA2 was the control class taught with conventional learning. The research instruments used were non-test and test. The test instrument was used to determine the knowledge of students in the cognitive domain, as many as 20 items with four choices that have been tested for feasibility. The non-test instrument used is a questionnaire to measure student learning independence. The pretest and post-test data of student learning outcomes in the experimental class were 40.5 and 84.5 while the control class data were 40.7 and 67.5. The percentage increase in n-Gain of student learning outcomes in the experimental class was 75% with a high category and the control class was 47% respectively with a medium category. Meanwhile, the percentage increase in N-gain of student learning independence in the experimental and control classes was 71% and 51% in the high and medium categories. There is a positive correlation between student learning independence and student learning outcomes, namely 0.635 with a moderate category.

This research aims to determine the effect of using Android-based Smart App Creator media with the STAD type cooperative learning model on students' learning outcomes and interest in chemical bonding material. The research was carried out from September to December 2023 at SMA Negeri 1 Silima Pungga-Pungga. This research uses a test instrument in the form of multiplechoice questions with 20 questions and a non-test in the form of a learning interest questionnaire with 30 statements. The sampling technique used in this research is random sampling, namely random sampling. The research sample was students in classes X-1 and X-6, totaling 36 people in each class. Hypothesis I test uses the right-sided t-test with the research results obtained by the value tcount > ttable, namely 5,36 > 1,666. Hypothesis II test uses the right-sided t-test with the research results obtained tcount > ttable, namely 11,57 > 1,666. Hypothesis Test III uses a correlation formula with the research results obtained rcount > rtable, namely 0,547 > 0,339. Based on the research results, it can be concluded that there is a significant influence on students' learning outcomes and interest in learning using Android-based Smart App Creator media with the STAD type cooperative learning model on chemical bond material and there is a relationship between students' learning interest and student learning outcomes taught using the media. Android-based Smart App Creator with a STAD type cooperative learning model on chemical bonding material.

Abstract: The guided inquiry learning model is one of the learning models that can improve student learningoutcomes and student learning activities which is a learning model where teachers and students determineand formulate problems together, and students actively seek and find answers and draw their ownconclusions. The purpose of the study was to determine the results of science learning on the material ofPlant Structure and Function of class VIII students of SMP Negeri 12 Medan. To determine the Effect ofthe Guided Inquiry Learning Model on Student Learning Outcomes on the Material of Plant Structure andFunction in Class VIII SMP Negeri 12 Medan. This research method uses a quantitative research method.The form of research is Quasi Experimental Design. The research design is a two group design. Datacollection techniques were carried out using pre-research observations, interviews with Class VIII scienceteachers, conducting written tests on students in the form of questions, non-tests or questionnaires, observingstudent activities, and documentation in the form of research images and photos and value documents relatedto the results. Data analysis using hypothesis testing (one-sided t-test) and N-Gain testing. Based on theresults of the t-test, the obtained t-value is 4.66> t-table 2.00. This means that the results of the hypothesistest t-count are greater than t-table. Next, based on the results of the N-gain test, the increase in learningoutcomes in the control class was higher, namely 69% compared to the increase in student learning outcomesof 52%. So that the Guided Inquiry Learning Model applied to the experimental class in this study has aneffect on student learning outcomes in the material on the Structure and Function of Plants in class VIII ofSMP Negeri 12 Medan.Keywords: Learning

The objective of this study is to determine the effect of the Problem Based Learning model assisted by animated videos on science learning outcomes in the topic of the Human Respiratory System among eighth-grade students at SMP Imelda Medan. The population of this research comprised all eighth-grade students at SMP Imelda Medan. The sample classes were selected using random sampling, with two classes chosen as the sample. This study employed a quantitative research method, specifically a quasi-experimental approach with a Pretest-Posttest Nonequivalent Control Group Design. Data collection techniques included pre-research observation, interviews with science teachers of grade VIII, written multiple-choice tests for students, and documentation during the research. Data analysis was conducted using hypothesis testing (one-tailed t-test). These data indicate that the implementation of the Problem Based Learning model assisted by animated videos significantly improves students' learning outcomes of eighth-grade students at SMP Imelda Medan on the topic of the human respiratory system.
