Abstract

ABSTRACT This research had the purpose to find out the difference between the students’ learning outcomes which were taught by using NHT type of Cooperative Learning Method Assisted Video as Media and Lectures Method Assisted Video as Media as well as to find out how large the effect of NHT type of Cooperative Learning Method Assisted Video as Media in XI IPA class of SMA Negeri 1 Sungai Ambawang. This research was Quasi Experimental Research Nonequivalent Control Group Design. The sampling technique was saturated sample based on the students’ daily tests scores. The techniques of data collection used measurement, indirect observation and direct communication techniques.
