Abstract :
The purpose of this research was to determine The Effect Application Of
The Problem Solving Method with Lesson Study Patterns On Student Learning
Outcomes and Student Learning Activities. This type of research experimental
research using quasi experimental design in the form of posttest-only control design.
The population in this study were all class X students of MA NW Sikur in the
2019/2020 academic year, which consists of 2 classes with 35 students. The sample
of this study was determined by simple random sampling technique. Class X IPA as
an experimental class and Class X IPS as a control class. The instrument in this study
is a test of student learning outcomes in the form of an essay totaling 6 items and
observation sheet of student. Based on the results of data analysis obtained the
average value of the post-test experimental class is 79.06 and the control class is
59,47. Whereas, hypothesis 1 and 2 testing uses statistical analysis with the t-test
formula at a significant level of 5% that is obtained by tcount of 8,41 and 7,11. After
being compared with ttable of 2.034, it shows that tcount (8,41 and 7,11) > ttable (2.034),
then H0 is rejected and Ha is accepted. Hypothesis 3 testing uses statistical analysis
with MANOVA with the help of SPSS For Windows 22 was obtained score sig to 4
tabel 0,00 than H0 is rejected and Ha is accepted. Thus it can be concluded that
"There is determine The Effect Application Of The Problem Solving Method with
Lesson Study Patterns On Student Learning Outcomes and Student Learning
Activities ".
