INVESTIGATE THE LEVEL OF TWELFS GRADE STUDENT UNDRESTANDING IN INTEGRAL CONSEPT BY APOS THEORY

The objective of this research is to study students' understanding of the concept of integral in the framework of APOS theory. Finding a method and approach leading to conceptual understanding of integral is a challenge faced by most of mathematics teachers. APOS theory is one that is used to study learning mathematical concepts at universities. This is a qualitative study using survey method. This paper reports the analysis of students' answers to seven questions about integrals of functions. According to the findings most students have failed to get a conceptual understanding of integral. They solve integral problems only if they have access to a routine solution. According to APOS theory most students are in action and process levels and a few manage to get higher levels and form a schema of integral.so we can use APOS to growth student undrestanding ib intrgral concept,for this we must work on teacher educvation in math.
