Abstract

Errors can't be avoided by learners in learning mathematics, including in problem solving. Educators should provide opportunities for learners to reflect and repair their errors. The wrong answer given by the learner may not necessarily result from the wrong thinking process. This is called pseudo thinking. Pseudo thinking in problem solving can be distinguished into pseudo-wrong and pseudo-true. The focus in this study is that pseudo-wrong students in solving geometric problems, that is, when learners answer wrongly but learners are able to explain reason properly. Pseudo thinking students make errors in understanding problem and implementing plan. Errors that occurs are misunderstanding of measure of line segment, failure to understand that triangles should be formed are a right triangle, error in applying Pythagorean theorem and the trigonometric ratios, and unable to apply triangle congruence to justify congruence of measure of two angles. Repair errors is done by implementing assimilation and accommodation process. Both of these processes involve the student's prior knowledge about concept of triangle, circle, trigonometry and Pythagorean theorem in solving problems. Through this improvement, students are able to solve problem of geometry correctly.
