This research aims to determine: (1) the influence of constructivistic and expository learning models on lesson study towards learning outcomes in teaching planning; (2) the influence of high and low critical thinking skills on learning outcomes in teaching planning; and (3) interaction between learning models and the ability to think critically about learning outcomes in teaching planning. The research method using quasi-experimental with a 2 x 2 factorial design. The statistical test using descriptive statistics to present data and continued with inferential statistics using two-way ANOVA with a significant level of α = 0.05 followed by further testing. The results of research obtained showed: (1) learning outcomes in teaching planning taught using constructivist learning model with character by lesson study are higher than learning outcomes taught by expository; (2) learning outcomes in teaching planning that have high critical thinking skills are higher than those with low critical thinking skills; and (3) there’s an interaction between the learning model and the ability to think critically about the learning outcomes of teaching planning
