Abstract


Abstract: Research on the application of the Structured Numbered Heads learning model was done to improve students learning achievement in the topics of the atomic structure and the periodic system of elements in class X MIA SMAN 5 Pekanbaru. This research was experiment based on pretest-posttest design. The sample consisted of two classes, which are X MIA 4 as experiment class and X MIA 3 as control clas that randomly selected after testing normality and homogeneity. Experiment class was a class treated by applying the Structured Numbered Heads learning model. Analyzed of data used t-test.
