A common problem in this research is how the results of the application of cooperative learning model NHT subject matter of heat transfer on the learner class X-B SMA Muhammadiyah Kupang semester academic year 2013/2014? Specifically, this research problem is: (1) How does a teacher's ability to manage the learning process by implementing cooperative learning model NHT? (2) How cooperative skills of learners in the learning process by implementing cooperative learning model NHT? (3) How completeness Learning Outcome Indicators (IHB) in learning to apply cooperative learning model NHT? (4) How mastery learning outcomes of students in learning by implementing cooperative learning model NHT? (5) How is the response of students to the learning process by implementing cooperative learning model NHT? The general objective of this study is to describe the results of the application of cooperative learning model NHT subject matter of heat transfer on the learner class X-B SMA Muhammadiyah Kupang second semester of the school year 2013/2014. By the purpose of this research are: (1) Describe the teacher's ability to manage the learning process by implementing cooperative learning model NHT; (2) Describe the cooperative skills of learners in learning by implementing cooperative learning model NHT; (3) Describe completeness Learning Outcome Indicators (IHB) to implement cooperative learning model NHT; (4) Describe the mastery learning outcomes of students by implementing cooperative learning model NHT; (5) Describe the response of students to the learning activities by implementing cooperative learning model NHT. This type of research is descriptive. The subjects were teachers (researcher) and X-B grade students of SMA Muhammadiyah Kupang, amounting to 24 people.
