ABSTRACT This aims of the research determine the effectiveness of remedial teaching on the achievement of students' mathematics learning outcomes in the inquiry model and the average difference with other treatments. The population in this research is the second semester of eighth grade students of SMP Negeri 22 Semarang academic year 2015/2016. Sampling was done by random sampling technique. With this technique, there are four classes as an experimental class is class VIII A as first experimental class treatment with remedial teaching in inquiry model, a class VIII B as second experimental class with remedial teaching in conventional models, a class VIII G as third experimental class with inquiry model, and VIII H as fourth experimental class with conventional models. The data collection is done by the method of documentation, written tests and interviews. Furthermore, the data were analyzed using the proportion test, the average similarity test, anova test factorial design and advanced test of Scheffe. The conclusion of this study showed that the remedial teaching in the inquiry model effectively to the learning outcomes of students with average results over 75 and the mastery proportion more than 75%.
