The Impact of Students Assessing the Level of Difficulty Test Item on Interest and Motivation in Learning Mathematics

According to Item Response Theory, the difficulty level is a characteristic of test item. The items that are on scale with ability parameter. However, this relationship has not been studied optimally, especially in students' interest and motivation learning mathematics. This study examines impact student involvement assessing item mathematics approach assessment as learning. involved 176 students from grade VII SMP MTs. High-level reasoning were adapted TIMSS items, while instruments used questionnaire. Data analysis percentages paired t test. results showed difference between before after estimating increased items. Therefore, increase mathematics, teachers can involve using
