The purpose of this research was to analyze the effectiveness of Knisley Mathematics Learning Model on students' mathematical communication ability. Type of this research was quantitative research. The population in this research was grade VII students of one of junior high school in Semarang at 2018/2019 school year. With cluster random sampling technique, class VII H was obtained as an experimental class with Knisley Mathematics Learning Model and class VII G as a control class with Problem Based Learning models. Data collection includes tests of mathematical communication ability. Data were analyzed by classical completeness test, average difference test, and proportion test. The results showed that: (1) mathematical communication ability with Knisley Mathematics Learning Model had not yet reached classical completeness ie 59% while control class completeness was 36%, (2) the average achievement of students' mathematical communication ability in the Knisley Mathematics Learning Model class was higher than the average achievement students' mathematical communication in Problem Based Learning Model classes, and (3) the proportion of students' mathematical communication ability achievement in the Knisley Mathematics Learning Model class is higher than the proportion of students' mathematical communication ability achievement in Problem Based Learning Model classes.
