Abstract

The aim of this research was to know the gain of students achievement that taught by using dubido. The research has been done in Chemistry Educational Study Program in Unimed. The experimental class was given treatment with teaching by using dubido media based on contextual. The experimental class has fulfilled the requirement for normality and homogenity test. The mean of pretest results and posttest results were 42.240 and 84.480. The increase of posttest results indicated that learning by using dubido based on contextual can improve students achievement. The increase of students achievement signed by gain percent with the percent of gain value was 73.3. The result of t test was obtained from tcount is more than t table (2.590 is more than 1.677) at alpha is 0.05, it means that the implementation of dubido based on contextual was given positive effect to increase students achievement.
