PENINGKATAN KUALITAS PEMBELAJARAN MATEMATIKA MELALUI PENERAPAN MODEL KOOPERATIF TIPE NHT DENGAN PENDEKATAN SAINTIFIK PADA SISWA SMA

The purpose of this study was to improve the quality of mathematics learning in this case learning outcomes and student learning activities in mathematics learning by using the Cooperative Learning Model Type NHT. The procedure used in this study was Classroom Action Research with two cycles, each cycles consists of 4 stages, namely planning, implementing, observing, and reflecting. Data collection techniques used are test and non-test techniques using test and observation questions then analyzed using quantitative data analysis. The results of this study showed that after the application of Cooperative Learning Model Type NHT can improve learning outcomes, learning activities and student responses. This can be seen from the increase (normalized gain) of learning outcomes from pre-action to cycle I is 0.57 and cycle I to cycle II is 0.30, this indicates an increase in learning outcomes in the medium category means meeting the indicators of success. Completeness of student learning outcomes in the first cycle of 61.76% has not met the indicators of success, then in the second cycle changed to 85,29% and met the indicators of success. The average percentage of student activity in pre-action was 39.85% changed to 75.15% in cycle I and 86.76% in cycle II. This shows an increase in student activity from pre-action to cycle II. Student activities reaching good categories means fulfilling indicators of success. The results of student questionnaire responses in the first cycle were 82.14% while in the second cycle it was 94.12%. This shows students giving positive to the learning model with a scientific approach. The conclusion of this study is that there is an increasing in the quality of mathematics learning in class X
