The observation 2nd graders learning experiences in mathematics according to computer prepared intelligent tutor system

The aim of this study was to investigate what kind of questions the primaryschool second grade students should be asked for the evaluation of the intelligenttutor system prepared on the computer from the point of student model and in thebehavior of subtracting two digit natural numbers by writing them one under theother or next to each other the necessary operation for `we borrow one from ten? or`we don?t borrow one from ten? in order to find out the source of the error in theprior knowledge and the effectiveness of the prior knowledge.224 Primary School Teachers in 29 different primary schools in Konak,Karşıyaka, Buca and Menemen in zmir completed the scale which has two parts and82 items.In the scale, Alpha Reliability of the part of prior knowledge section ?two digitnumbers The necessary operation for 'we don?t borrow one from ten? ? is 0,84, of thequestions aimed to find out the deficiency of subject is 0,94. In the second part of thescale, Alpha Reliability of the part of prior knowledge section ?two digit numbers thenecessary operation for `we borrow one from ten? is 0,86, for the questions aimed tofind out the deficiency of subject is 0,95.
