The Influence of the Numbered Heads Together (NHT) Learning Model on Students’ Learning Interest in Christian Religious Education and Character for Grade XI Students of SMA Negeri 1 Sipoholon

Abstract

The purpose of this study was to determine the extent of the influence of the Numbered Heads Together (NHT) learning model on students’ interest in learning Christian Religious Education and Character among Grade XI students of SMA Negeri 1 Sipoholon in the 2024/2025 academic year. The research employed an inferential quantitative method. The population consisted of all Grade XI students of SMA Negeri 1 Sipoholon in the 2024/2025 academic year, totaling 261 students, from which a research sample of 64 students (25% of the population) was drawn. Data were collected through a closed questionnaire consisting of 52 items. The results of data analysis indicated that the Numbered Heads Together (NHT) learning model had a positive and significant influence on students’ interest in learning Christian Religious Education and Character. This finding was evidenced by the following analyses: 1) Analysis prerequisites test: a) A positive correlation test yielded r_xy = 0.506 > r_table (α = 0.05, n = 64) = 0.244. b) A significance test of the correlation showed t_count = 4.621 > t_table (α = 0.05, df = n – 2 = 62) = 2.000. 2) Effect test: a) Regression equation test resulted in the regression equation Ŷ = 25.73 + 0.58X. b) Regression coefficient of determination (r²) = 25.6%. 3) Hypothesis testing using the F-test showed F_count > F_table (α = 0.05, df numerator k = 22, df denominator = n – 2 = 62), namely 21.33 > 1.39. Thus, the proposed hypothesis (H_a), stating that there is a positive and significant influence of the Numbered Heads Together (NHT) learning model on students’ interest in learning Christian Religious Education and Character among Grade XI students of SMA Negeri 1 Sipoholon in the 2024/2025 academic year, is accepted, while the null hypothesis (H₀) is rejected.
