PENGARUH MODEL PEMBELAJARAN THINK PAIR SHARE DENGAN MENGGUNAKAN PETA PIKIRAN TERHADAP HASIL BELAJAR SISWA KELAS X SMU PADA POKOK BAHASAN STRUKTUR ATOM

This research aim to show the learning outcome of students of class X high school on the subject of atomic structure was taught to think pair share learning model by using mind map was higher than the learning outcome of students who
was taught using the conventional. The samples are students from two class X in SMA Negeri 9 Medan where each class consist of 38 students which one for control class with conventional method and the other class for experiment class
with learning model TPS and using mind map. This research using objective instrument test. Before testing the hypothesis first tested for normality and homogeneity. From the tests that the samples obtained were normally distributed and homogeneous. Results of research was conducted in SMU Negeri 9 Medan obtaining the average learning outcome of students who was taught by TPS,learning model using a mind map (X = 66.95 ± 6.49) was higher than the learning outcome of students was taught by conventional methods ( X = 63.58 ± 6.82). The hypothesis in this research was tested using t-test on the right, with the hypothesis testing results obtaining thitung = 2.203 and ttable = 1.668 at α= 0.05 level. This means there is theinfluence of the learning model TPS using mind map to student learning outcome.
