INTRODUCTION
Education is essential in providing qualified learners as human resources.There are so many important things in human development and life, one of which is education, with education, the birth of an intelligent society capable of building creativity and independence for its nation and country (cahyadi al, 2021).At the 2003 national education system, article no. 20, section 3, and 4, which affirms that education is held asa life-long process of cultivating and empowering learners by modeling, building volition, and developing creativity, learners in the learning process (pangestu al., 2019).The primary purpose of education is for optimum learning and learning experiences.Learning is a form of activity where interactions in learning and teaching learners with educators and resources learn to develop behaviors consistent with the educational purpose (hamalik, 2003: 2).
In the learning process are several subjects, one of which is a mathematical subject.The learning process is a system.Thus, the standard process for improving the quality of education can begin with the degenerating of each component that can shape and influence the learning process (sanjaya, 2006: 13).Mathematics isa deductive science that deals with hieratic ideas or concepts and receives generalization based on deductive reasoning (the goddess et al, 2021).According to the sumardyono (2004: 30), mathematics has 6 characteristics of abstract objects of study, based on agreement, deductive thought patterns, has empty meanings, attention to the talking universe, is consistent in its system.
The process of math learning goes on, the learning is still centered on the teachers (teacher center) and the learning methods used are just the lecture method, most of the learners are still embarrassed to ask and express their opinions, the responsibility of learners who are so lacking in the tasks given by the teacher, the lack of interaction between the learner and the learner, And most learners are less active so that learning participants are only passive.It is this factor that makes learners struggle with understanding the material presented by teachers, resulting in cahyadi et al, 2021).
The factor affecting the poor learning result is the learning process in the classroom, teachers tend to use conventional learning models (goddess et al, 2021).Learning is also the result of an assessment of a learning process expressed in the form of symbols, Numbers, letters, or sentences (marseno et al, 2021).According to hamalik (2003) the results of study are patterns, actions, values, understanding, and attitudes and perceived and capability.From both statements it may be inferred that a sense of learning is a real change in the conduct of learners after a teaching process that fits the teaching objective (jihad, 2012: 15).
One alternative cooperative learning model that can be used in math study isa cooperative head together.Continuing head together (NHT) or thinking together is a type of cooperative learning designed to involve learners who study the material involved in a lesson and check their understanding of the content of the lesson (pangestu & kadir, 2019).Recurring head together (NHT) was first developed by spencer kagen to involve more learners in studying the material involved in a lesson and checking their understanding of the content of the lesson.Steps that can be taken in this learning model as follows (pangestu & kadir, 2019): phase 1: numbering (teacher divides learners into groups of 3-5 and to each group member are numbered between 1-5), phase 2: ask questions (teacher asks the learner questions, questions can vary), phase 3: Think together (learners unify their opinions on the answer to the question and convince each member of his team to know the team's answer), phase 4: answer the question (the teacher calls a particular number, then the students from each group of the same number raise their hands and prepare answers for the entire class).
Among the more full-head together cooperative learning models (NHT) are the interactions between learners through discussions/learners together in resolving problems.B) both clever and weak learners benefit from cooperative study activity.C) by cooperative work in this way, the construction of knowledge will be greater/likely for learners to come to their expected end.D) could provide learners with opportunities to use questions, discussions, and develop leadership skills (pangestu & kadir, 2019).
Based on the above background, the purpose of the study is to examine the influence of the cooperative study model, typical head together (NHT) on the increased results of learning in secondary secondary math subjects.

METHODOLOGY
The study used the SLR (literature review) method.Literature review is a method of study conducted by identifying, reviewing, evaluating and interpreting.In this study, researchers conducted a systematic review of journals and other related resources and followed established procedures (triandini, etc., 2019).
Based on predetermined steps, researchers conducted a systematic search for literature studies conducted using a publication or publication application.The key word used is "free-head together (NHT)," "the result of learning," "math education."The criteria for identifying the study of literature is the study associated with the increased results of studying the mathematics of learners by using the distinctive head together learning model and research.Literature obtained is selected and analyzed according to predetermined criteria.Obtained data linked to key words that are as many as 20 articles.The criteria were selected to be 10 articles.Based on search results, we found 10 accredited national journals on Google scholar.The articles used are the same journal articles as research.The results of this study are summarized in this study and discussed together.The scientific criteria for the information articles are the scientific articles that have been published in a journal for at least 7 years.From 2017 to 2023.

RESULTS
The results of research data included in this literature study are analysis and summary of the articles documented regarding NHT models and the learning of learners presented at the table below.Based on data analysis in this journal, the NHT learning model has a significant impact on students' learning math, with the students' math given the NHT learning model tend to be better than the students' math given to TPS 'study models.This can be seen at table 1  The purpose of this study is to know if there is a significant positive impact of applying the NHT type of cooperative learning model to the results of studying the eighth year of the public junior high school student year 2017/2018.Based on normal test analysis and variance homogeneity analysis, it has been found that a fraction of the data resulting from studying student mathematics in normal distributed experiment and control groups and having homogeneous variants.The normal test results using the chi-square (paren2) test on experiment groups and control groups in a series of 8.547 and 5.351 with a 5% degree of importance.Whereas the results of the homosexuality test using the f test on experiment groups and control groups respectively were 1.69 and 1.86 with a 5% significance.Next, hypothesis tests using tests -t obtained tests obtained, anonymously-projected projected = 4.47 and projected projected projected =61 In other words, ata level of 5% significance, there is a significant positive impact of applying the NHT type of cooperative learning model to the results of studying the eighth year of the public junior high school student year 2017/2018.

The Influence of the NHT Type Analysis indicates a difference in average grades prior to treatment of 56.59 and of thought and social skills (alfian, etc., 2022).The cooperative learning model, which types volunteer head together (NHT) is a learning process by dividing learners into several groups and each learner is numbered, and then randomly the teacher calls the student's number (puspaningrum, etc., 2022).Using the NHT type of cooperative learning model in the learning process, being able to make the materials presented more easily understood learners, learners able to explore their own knowledge, and learners capable of resolving the issues set forth.This is seen from the scientific research of halomoan lumbantoruan (2022), lukman magistrate muhaiminrum (2022), rizka fajriana dasari (2022), beny septian sukmo marseno, la masi, hasnawati (2021), ni putu kusuma goddess, kadek rahayu puspadewi, I made wena (2022), shamsiara nur (2022), the master of pangestu and kadir (2019), astuti alfrida destyanrum, supandi, Muhammad saifudin zuhri (2022) who claims that the cooperative learning model, which types head together (NHT) can improve.

CONCLUSIONS AND RECOMMENDATIONS
Studies based on the motode literature review review can conclude that application of the elevate head together learning model (NHT) affects the learning of the mathematics of learners as well as that of learners of learners.Literature data sources acquired and analyzed state the results of studying mathematically learners who use advanced head together (NHT) learning models (NHT) than those who use conventional models.Alfiana, Siti., Sutirna., Hidayati, Nita.
