Abstract
First year students in a junior high school were taught about household economy in a coeducational situation. This paper surveyed the changes of consciousness toward instruction in relation to teaching effectiveness. The results are as follows : 1. Subject matter adopted mainly on defraud businesses, changes of decision-making were confirmed before and after teaching with significant differene. 2. The rate of true answers before and after teaching showed significant difference on four of five subject matters. Fixed rate on post-test after three months showed positive results ; that is, ninety-eight percent on the average. Partial reason for this high average seemed to have relation with practical teaching. 3. On reference between consciousness and the rate of true answers, understanding after teaching was highly related to the rate of true answers. Therefore in order to grasp teaching contents accurately, it is necessary to devise a method to raise their level of consciousness for instruction as well as contents.
