COOPERATIVE TYPE NUMBERED HEADS TOGETHER EFFECT ON STUDENT’S ACHIEVEMENT IN EXPANSION TOPIC

Abstract

ABSTRACT

This research was aimed to know 1) Student’s achievement in physics by using numbered heads together (NHT). 2) Student’s achievement in physics by using conventional learning model. 3) The effect of numbered heads together (NHT) on student’s achievement especially on expansion topic. The population was nine classes student grade VII in SMP N 1 Tebing Tinggi. The sample was two classes obtained by cluster random sampling. The sample was VII₅ by using numbered heads together (NHT) and VII₄ by using conventional learning model. Instrument has 20 questions and tested validated. The mean of pre-test in VII₅ was 38.15 and in VII₄ was 38.52. After that learning model applied, and then done the post-test. The mean of post-test in VII₅ was 78.15 and in VII₄ was 73.52. In hypothesis testing obtained t_count > t_table at significant level 0.05. So, can be concluded student’s achievement of VII₅ better than VII₄.
