Pengaruh Model Numberred Heads Together (NHT) Berbantuan Media Kantong Matika Terhadap Hasil Belajar Matematika: This Study Aims to Determine Whether the Numberred Heads Together (NHT) Model With the Help of Bag Matics Media Has an Effect on the Mathematics Learning Outcomes of Fourth Grade Students in Pingit Village, Pringsurat District, Temanggung Regency. This Research Is a Type of Quasi-Experimental Research With a Non Equivalent Control Group Design Model. The Sample Used Was 20 Students in Class IV Consisting of 10 Students As the Control Class and 10 Students As the Experimental Class. The Sampling Technique Used Is Saturated Sampling. Method of Collecting Data Using Tests That Have Been Tested for Validity Using the Product Moment Technique and Reliability Testing Using the Cronbach Alpha Formula. Data Analysis Used Non-Parametric Statistical Techniques Mann Whitney U Test Assisted by the IBM SPSS Statistic 24 Program With a Significance Level 5%. This Is Evidenced by the Difference in the Average Post-Test Result of the Control Class and the Experimental Class. The Control Class Average Was 57,7 and the Experimental Class Average Was 85 After Being Given Treatment. Results of Hypothesis Testing Carried Out Using the Mann Whitney U Test Assisted by the IBM SPSS Statistic 24 Program, the Z Value Obtained Is -3,797 With Asymp. Sig. (2-Tailed) of 0,001 < 0,05. Based on This Research, It Can Be Concluded That the Use of the Numberred Heads Together (NHT) Model With the Help of Bag Matics Media Has an Effect on Learning Outcomes in Mathematics. proceeding 2021, 371-378.
