Diagnosing Learning Difficulties Related To The Equation And Inequality That Contain Terms With Absolute Value
The aim of this study is to diagnose the learning difficulties about the equation and inequality that contain terms with absolute value and to make suggestions for the teachers in this respect. The sample of the research is composed of 170 ninth grade students enrolled in four different high schools. Data of the research is composed of a knowledge test that contains 10 open-ended questions and interviews made with the students. According to the acquired data, it has been detected that the students experienced difficulties in forming a correct solution set since they acted as if there were no absolute value while finding the solution set of this equation and inequality, and could not fully internalized the concept of absolute value.
