Students’ learning results on trigonometry material through Numbered Heads Together cooperative model with mnemonic strategy

Abstract

Trigonometry is one of materials at Grade X of second semester of senior high school. It is an important material to be learned because it is not only an examination material, but also has a continuation at Grade XI. In addition, the material has many contributions to daily life, such as tree height calculation and determination of Qibla direction. In the learning of trigonometry, mnemonic strategy can be implemented, which is a way to help the students remember the information more effectively and easily. Mnemonic learns new information by linking the existing information through visual images or letters and words combination. Therefore, this research was conducted in terms of trigonometry material learning through NHT (Numbered Heads Together) cooperative learning with mnemonic strategy at Grade X of MAN Darussalam. The research is aimed to find out students’ learning mastery classically as well as individually and to find out students’ responses toward trigonometry learning process through mnemonic strategy that was applied in cooperative model of NHT type. The research population was all of Grade X students of MAN Darussalam while the sample was 31 students of X-IPA 1. Based on the students learning result, the lowest score was 50, the highest was 100 and the mean was 81.8. This means that the mathematics achievement of MAN Darussalam Grade X students reached successful or completed stage. While students’ responses toward learning activity which based on the observation showed less effective. It could be seen from students’ responses percentage toward positive statement that was less than 80%.
