^{3}The problem of this research is (1) whether there are an increase of mathematics learning outcomes of students who are taught using Knisley learning model with brainstorming method, (2) whether there is an increase of mathematics learning outcomes of students taught using conventional learning model, (3) students class IX SMP Negeri 1 Watubangga after being taught using Knisley learning model with brainstorming method is more effective than the result of learning mathematics students after being taught using conventional learning model.

The population in this study is all students of class IX SMP Negeri 1 Watubangga academic year 2017/2018. IX.a, IX.b, and IX.c in this study the sample was taken using cluster random sampling, with the technique obtained class IX.a as the experimental class by using Knisley learning model with brainstorming method and IX.b as control class with using conventional learning models.

Based on pre-test and post-test result in experiment and control class there is the improvement of learning outcomes where improvement of learning the result of experimental class mathematics = 0,375 including medium category and improvement of learning the result of control class = 0, 2699 including low category. The result of hypothesis analysis is t_{count}> t_{table }(3,423> 2, 0129). The result of pre-test experimental class average analysis = 60, 1396, posttest = 74,78 and control class = 60,3471, post-test = 71,2892. This means that the results of mathematics learning of students who obtained the material using Knisley learning model with brainstorming method are more effective than the result of teach mathematics students who obtained the material using conventional learning model.

Based on the result of the research, it can be concluded that there are improvement of students’ mathematics learning outcomes in experimental class and control class and mathematics learning result of students who get the material using Knisley learning model with brainstorming method is more effective than mathematics learning result of students obtaining material using conventional learning model.
