TY - JOUR N2 - KONCAMA Model is a learning model with conceptual conflict in mathematics problem solving. This model is developed to reinfore students? understanding on mathematics concept and make students active in mathematics learning. Learning activities within this KONCAMA model consist of stages as the following: orient students to conflict?based?problem (preconception), organize students to learn and tackle conflict (reapraisal of cognition), assist students to investigate and solve problem individually and in group (cognition development), develop and display the results of problem solving (comunication), along with analyze and evaluate the process of problem solving (evaluation). KONCAMA Model is a practical and effective learning model to be implemented in geometry learning of Senior High School students.
