The purpose of this research is for knowing the effectivenes of cooperative learning with Student Teams Achievement Division (STAD) model and Think Talk Write (TTW) model by using e-modul toward problem sollving ability in presentation of data. The population of this study is the students of SMP PGRI 01 Semarang in academic year 2017/2018. Sample selection tecnique used is the cluster random sampling technique. As the samples taken from two experimental classes, the experiment classes I using STAD model by using e-modul and the experiment classes II using TTW model by using e-modul. The result of the research showed that (1) Students' mathematical problem solving ability using e-module assisted Student Teams Achievement Division (STAD) learning model and e-module assisted Think Talk Write (TTW) learning model to achieve KKM. (2) There are differences in mathematical problem solving abilities of students who get e-module assisted Student Teams Achievement Division (STAD) learning models, e-module Think Talk Write (TTW) learning models and conventional learning models. (3) Mathematical problem solving ability of students who get e-module assisted Student Teams Achievement Division (STAD) learning models better than conventional learning models. (4) Mathematical problem solving ability of students who get e-module assisted Think Talk Write (TTW) learning models better than conventional learning models. (5) There is an effect of students 'activeness on students' mathematical problem-solving abilities in the e-module assisted Student Teams Achievement Division (STAD) learning model. (6) There is an effect of student activity on students' mathematical problem-solving abilities in the e-module Think Talk Write (TTW) learning model. (7) There is an effect of student activity on students' mathematical problem-solving abilities in conventional learning models.
