This research aims to determine the influence of the numbered head together (NHT) model assisted by audio-visual media on student learning outcomes in food chain material for class V of SD Negeri 060938 Medan for the 2023/2024 academic year." The population in this study was 48 students, namely all class V students at SD Negeri 060938 Medan for the 2023/2024 academic year. This type of quasi-experimental research uses a selection technique, namely the total sample in the VA class as an experimental class and is taught using the Numbered Head Together (NHT) Model assisted by audio-visual media. Class V B as a control class is taught using the Numbered Head Together (NHT) model. The research data collection technique is a test of student learning outcomes in the form of an essay test. Data analysis uses prerequisite tests (normality, homogeneity) and hypothesis testing uses the t test. Based on the results of data analysis, learning outcomes can be seen from X̅, experimental class 82.75 and X̅ control 77.08. Post test data with the experimental class Lilifors test was obtained L₀ = 0.1961 < L_(0.05)(24) = 0.2036 for a = 5% of the total number of 24 students, then H0 was accepted, so the learning outcomes data taught using the Numbered Head Together Model (NHT ) assisted by normal distributed audio visual media. And the learning outcomes data for classes taught using the Numbered Head Together (NHT) Model were tested for normality using the Lilliefors test, obtained L₀ = 0.1992< L_(0.05)(24) = 0.2036 for a = 5% of the number of 24 students, then H₀ was accepted, so the data Learning outcomes taught using the Numbered Head Together (NHT) learning model are normally distributed. Based on the calculation results, the value obtained is F = 1.08 < F_{(0.05)(21)(19})= 1.97 for a = 5%, n₁ = 24 n₂ = 24. So H0 is accepted, so that the learning outcomes data for the class taught by the Numbered head together model ( NHT) assisted by audio visual media and classes taught using the Numbered Head Together (NHT) model have homogeneous variance. It can be continued by testing the hypothesis with an independent test formula between two factors of learning outcome data for classes taught using the Numbered head together (NHT) Model assisted by audio visual media and classes taught using the Numbered head together (NHT) Model, so that the result x₂ = 6.81> x_2(0.95)(2) = 5.99 because x₂ > x_2(0.95)(2) then H₀ is rejected and H₁ is accepted.
