A content of the learning process due to raise the intensity of the independent activity was investigated on the educational content model for manual cutting. From the result for the slippage of cutting hour and truncation error in the cutting test with the double edged manual saw, the pupil greatly sensed the slippage of the body reaction, especially in the difference between the selections of the serration. Above slippage for the operation of cutting performance and accuracy in the manual sawing was correspondent to the psychological slippage. The result revealed that it was possible to perform the manual sawing operation in basis on the evaluation of independent activity of the slippage. In addition, the manual sawing operation, which utilized the difference between the selections of the serration in the learning of cutting processing, was easy to sense the slippage of the operation, and the difference included the element to raise the independent activity.
