Abstract
This study was made on junior high school students for their knowledge and experience about an electric washing machine in order to inquire into "washing" lessons as they ought to be in homemaking education. The results of the study were examined by stages of development and by sexes. These results were compared with those of a previous study made on sixth-year school children. The subjects were 90 students who entered the Junior High School Attached to Kyoto University of Education in 1977. The method used was an interview; 14 items of study were set up according to the procedures for washing operation. The electric washing machine used was double sink type which is most widespread among the average households. The results are as follows : 1. The number of girls having experience in using an electric washing machine is greater than that of boys. 2. The percentage of correct answers to all items for the 2nd-year examinees is about 9% higher than that obtained when they were in the 1st year grade. The percentage for the 1st year graders is about 8% higher than that of the 6th-year elementary school children. 3. The boys surpass the girls in the percentage of correct answers in either grades, and this difference decreases as the school year advances. 4. The 2nd year students whose percentages of correct answers are higher than those they got in the 1st year grade make about 55%, while those whose percentages become lower make about 28%.
