This research uses a quasi-experimental method with a pretest and post-test control group design research design. This research uses the Numbered Head Together Cooperative Learning model to improve student learning outcomes at SMA Negeri 2 Tondano for the 2022/20223 academic year. The sample in this study was class. The average post-test score obtained in the experimental class was 87.7, and the average in the control class was 78.1. The data analysis technique used is the t-test with the condition that the data comes from a normally distributed and homogeneous population—test normality using the Lililefors test and homogeneity. Based on the hypothesis of the research statistical data, a tcount of 2,730 was obtained. Based on the ttable with α=0.005 and degrees of freedom (dk) = n1 + n2 -2 =20+20-2= 38, By looking at the ttable, we get ttable = 1.688. So tcount is greater than ttable, namely tcount = 2,730 > ttable = 1,688. Thus, according to the test criteria, if tcount > ttable, then H0 is rejected, so hypothesis H1 is accepted, and it is concluded that there is an influence of using the Numbered Head Together model on student learning outcomes in the human respiratory system material at SMA Negeri 2 Tondano.

The problem that occurs in this study is the low learning outcomes caused by a lack of teachers in using models and media in learning. Alternatives to solving these problems are using the Problem Based Learning model, Indonesian Realistic Mathematics Education, and Number Head Together. The research objective is to describe the activities of educators, students, and to analyze learning outcomes. The approach used in this discovery is a qualitative approach with the type of PTK, which is carried out in 2 cycles consisting of three meetings. The subjects of this study were 18 grade VI students at SDN Kelayan Selatan 10. Qualitative data obtained through observing the activities of educators and students. While quantitative data through measurement techniques with individual written tests. Data analysis in this finding uses descriptive analysis techniques and cross-tabulations translated into tables, graphs and interpretations with percentages. The results of these findings show that educator activities get a score of 24 in the "very good" category. experienced an increase from a score of 30 to 36 in the "Very Good" category. Classical student activities reached 100% in the "very active" category. As well as student learning outcomes have achieved 100% completeness classically and individually. Based on these findings it can be concluded that using the PBL, PMRI, and NHT models can increase learning activities and outcomes.

The aim of this research is to determine the positive and significant influence of the Numbered Head Together (NHT) Cooperative learning model on the active learning of PAK class IX students of SMP Negeri 3 Lintongnihuta for the 2023/2024 academic year. The method used in this research uses quantitative descriptive methods. The population is all class IX students of SMP Negeri 3 Lintongnihuta for the 2023/2024 academic year who are Christians totaling 191 people and a sample of 48 people was determined, namely 25% of the total population using random sampling techniques. Data collection used a closed questionnaire with 40 items. The results of data analysis show that there is a positive and significant influence of the Numbered Head Together (NHT) Cooperative learning model on the active learning of PAK class IX students at SMP Negeri 3 Lintongnihuta for the 2023/2024 academic year. Based on the positive relationship test, the value obtained is rxy = 0.606 > rtable(=0.05, n=48) = 0.284, thus it is known that there is a positive relationship between variable ttable(=0.05,dk=n-2=46)= 2.021, thus there is a significant relationship between variable X and variable Y. Regression coefficient of determination test (r2) = 36.8%. Influence test: Regression equation test, the regression equation Y ̂="2.17"+0.63 63. Thus Ha is accepted and H0 is rejected.

The lack of literacy regarding the values ​​of the Pancasila ideology causes students' understanding to be low, this is proven by the students' scores being still below the KKTP, namely 75. Then also when interacting in class, some students say things that are impolite, make fun of each other, dress some less neatly, and less orderly. Besides that, the way of learning is monotonous and lacks enthusiasm. Then learning is less varied. This research aims 1). Knowing the teacher's activities in implementing the number heads together type Cooperative learning model in increasing students' understanding of the values ​​of the Pancasila ideology. 2). find out students' activities in implementing the number heads together type cooperative learning model in increasing understanding of the values ​​of Pancasila ideology 3). Find out the results of implementing the number heads together type cooperative planning model in increasing understanding of the values ​​of the Pancasila ideology. The research method used is classroom action research. Data collection uses observation and also written tests. The subjects of this research were PAI teachers and 12 students. The results of this research are as follows: 1). The teacher's activities in implementing the Number Head Together (NHT) learning model in class V of SDN 2 Tumbang Kalang were declared successful. This statement is in accordance with the observation results of almost all of the 21 learning process items being implemented. Likewise, the model applied from the six five learning steps has been fulfilled. 2). Students' activities in applying the Number Head Together (NHT) learning model in class V of SDN 2 Tumbang Kalang can increase in cycle II. This can be seen from the 13 activity items from introduction to conclusion, almost all of which were fulfilled, as well as the model implemented, almost all of which were fulfilled. 3). The use of the Number Head Together (NHT) learning model in class V of SDN 2 Tumbang Kalang can increase understanding of the values ​​of the Pancasila ideology in cycle I, namely 66.66% and increase in cycle II to 91.66% with an average class score of 70 in cycle 1 to 78.33 in cycle II

This research was motivated by the low learning outcomes of class VIII FIKIH MTsN 10 Agam. Researchers see the low UTS scores and the way student learn is still lacking during the FIKIH learning process. The hypothesis and this research is that the use of the Number Heads Together (NHT). On the learning outcomes of class VIII FIKIH MTsN 10 Agam. This research is a quantitative research using a quasi – experimental research design. The population in this study were all students of class VIII MTsN 10 Agam and the sample classes were class VIII 2 and class VIII 4. The instrument that the researcher used was the results of the FIKIH subject test in the form of multiple choice questions. As many as 20 questions with als material. The result of the reseach conducted by the researcher showed that the percentage of students completeness was hinger than the percentage of students completeness in the control class average score of 79,76 in the experimental class while in the control class there where  21 students who achieved KKM only 8 students with an average of 62,38 with a percentage of 86% experimental completeness and control class completeness 38% influence of the Number Heads Together (NHT) cooperative learning model on student learning outcomes in the FIKIH alms subject class VIII MTsN 10 Agam

The background to this research is that students lack enthusiasm and are less active in the Fiqh subjects taught by the teacher during learning. Lack of cooperation can trigger students to be active and discuss learning with their friends. Based on this, the researchers tried to offer a Numbered Head Together (NHT) Cooperative learning model. The formulation of the problem in this research is how much influence the Numbered Head Together (NHT) Cooperative Learning Model has on student learning activities in the Class XI Fiqh subject at MAN 1 Bukittinggi City. This research aims to determine how much influence the Numbered Head Together (NHT) Cooperative Learning Model has on student learning activities in the Class XI Fiqh subject at MAN 1 Bukittinggi City. The type of research used in this research uses quantitative research methods with a quasi-experimental approach. In this study, a nonequivalent control group design was used. The population in this research were all class XI students at MAN 1 Bukittinggi City. Sampling was carried out randomly and class XI IPS 2 was selected as the control class and class XI IPS 3 as the experimental class. The results of this research can be explained that there is an increase in the learning activity of experimental class students with the Numbered Head Together (NHT) model compared to learning in the control class without any treatment. Based on hypothesis testing, it is known that there are differences in fiqh learning activities between experimental class and control class students, namely based on the t-test, tcount = 3.491 and ttable = 1.66. Based on the results obtained, the value tcount > ttable so that H0 is rejected and H1 is accepted. This means that the Numbered Head Together (NHT) learning model influences students' fiqh learning activities.
