Pengaruh Penerapan Model Pembelajaran Numbered Head Together terhadap Hasil Belajar Matematika Siswa

Abstract

The problems studied in this study relate to the less than optimal achievement of students' mathematics learning outcomes. The purpose of this study was to determine the effect of the Numbered Head Together learning model on mathematics learning outcomes for grade VIII Odd Semester students of SMP Negeri 27 Bandar Lampung in the 2021/2022 academic year. This study used an experimental method with the population in this study, namely all eighth grade students of SMP Negeri 27 Bandar Lampung which consisted of 8 classes with a total of 242 students. Meanwhile, two classes were taken as samples, namely class VIII A as the experimental class that applied the Numbered Head Together learning model, and class VIII E as the control class that applied the conventional learning model. Samples were taken using cluster random sampling technique. To find out the students' mathematics learning outcomes, the author conducted a test in the form of an essay as many as 10 questions which had been tested for validity and reliability. Hypothesis testing in this study uses the t-hit formula. From the results of hypothesis testing using the t-hit statistical formula, the value of t = 2,93 is obtained. From the t distribution table at a significant level of 5%, it is known that t = 1,67 then  which means that the average mathematics learning outcomes of students who use the Numbered Head Together learning model are higher than the average mathematics learning outcomes of students who use the model. conventional learning.
