Abstract

Pembelajaran Kooperatif Tipe NHT Berbantuan Multimedia Mengacu pada Cognitive Load Theory untuk Meningkatkan Hasil Belajar Abstract: This study aims to determine the application of cooperative learning Numbered Head To-gether (NHT) with multimedia-assisted cognitive load refers to the theory that can improve mathematics learning outcomes. The study design was a class action research conducted by 2 cycles. Each cycle consists of 3 sessions or 6 x 35 minutes. Research subjects fifth grade students of SDN 124/IV Jambi with 32 students. Implementation cycles through three stages, namely the initial activity/apperception, core activities include; (1) numbered, (2) questioning, (3) heads together, (4) answering, and closing activities. Each stage accompanied by a power point slide show as a supporting medium to convey information. The results showed that the students are able to participate actively in the learning, increasing curiosity, build self-confidence, social interaction among students increased, the emergence of a sense of responsibility to the individual, as well as good cooperation in the understanding of knowledge.
