Student Improvement by Applying the Numbered Heads Together (NHT) Approach to Basic Subjects of Vocational Competence in a Vocational High School in Indonesia

This research aims to improve the learning activity and achievement of a 10^th grade class made up of 30 students in a vocational high school located in the city of Surakarta, Indonesia, by applying the Numbered Heads Together (NHT) approach. The experiment was divided into two stages of four activities each: planning, implementation, observation, and reflection. The comparative descriptive procedure was then used to analyze the data. Prior to the researach implementation, the learning activity was relatively low in the pre-stage of the experiment. However, after the NHT approach, the percentage of active students increased in stage 1 and stage 2. The result of the test also suggested a similar trend in student achievement. From this it can be concluded that the application of the NHT learning model improves engagement within the learning activity as well as the level of achievement.
