EFEKTIVITAS MODEL PEMBELAJARAN NHT DALAM MENINGKATKAN PENGUASAAN KONSEP SISWA MATERI IKATAN KIMIA
Abstract
This research aimed to describe the effectiveness of NHT learning model to increase the students concept in the chemical bonds topic. This research used quasi experiment method with non-equivalent (pretest-posttest) control group design. Population of this research was students of the 10th grade in SMA Tri Sukses Natar on 2012/2013 academic year. This research used two classes as sample where they were taken by using purposive sampling. The results showed that the average of n-Gain of students concept in experimental and control class were 0.58 and 0.49, respectively. Based on the results of hypothesis testing, NHT learning model was effective to increase students concept in the chemical bonds topic.
