PENERAPAN STRATEGI MEA (MEANS-ENDS ANALYSIS) DALAM MENINGKATKAN KEMAMPUAN BERPIKIR KRITIS MATEMATIK
Teaching mathematics in schools still tends to emphasize the target of material completion rather than paying attention to the process of forming mindset in understanding an understanding or solving a problem of a mathematical problem. For this reason, changes need to be made in the thinking process of students so that students have good thinking skills. One of the skills that must be developed to achieve these goals is critical thinking. Critical thinking skills as part of psychomotor aspects and critical thinking skills as part of cognitive aspects, both must be related to train students in forming mindset in analyzing, making choices and drawing conclusions in a problem to improve learning outcomes. The facts in the field revealed by the teachers that it is not easy to improve students' critical thinking skills. There needs to be a certain strategy applied in the learning process. One strategy that is assumed to be appropriate is the MEA (Ends-Analysis Analysis) strategy. Through the MEA strategy, students are faced with a mathematical problem and require students to divide the problem into several subproblems, then complete it in each of the subproblems. This encourages students to get used to critical thinking, so that mathematical critical thinking skills can increase. The purpose of this study was to find out: (a) teacher and student activities with MEA strategies, (b) students 'critical thinking skills in each cycle through the MEA strategy, (c) students' critical thinking skills after following the entire cycle through the MEA strategy, ( d) student attitudes towards learning with the MEA strategy.

KONTRUKTIVISME DALAM PEMBELAJARAN MATEMATIKA
The concept of constructivism was first put forward by an Italian national named Giambatista Vico around 1710, He explained that "knowing" means "knowing how to make something". The theory assumes that knowledge is the result of a construction process from various experiences and results of interactions with the environment. In the learning process (acquisition of knowledge) with contrutivism learning begins with cognitive conflict. Cognitive conflict occurs when the interaction between the initial conception that students have with new phenomena that cannot be integrated just like that, so that changes in cognitive structure modifications are needed to achieve balance. Then this cognitive conflict can only end with self-knowledge, this knowledge will be built by itself through experience in interaction with the environment. This event is ongoing as long as students receive new knowledge.
