A study was conducted to analyze the structure of pupils' consciousness about their classroom and to examine its relationship with the pupils' evaluation of physical education classes. In order to analyze the structure of pupils' consciousness about their classroom, a questionnaire consisting of 25 items was prepared and distributed to 1550 pupils from 44 classes in 5 elementary schools. Four factors were extracted by means of factor analysis : 1)human relationship, 2)motivation for learning, 3)activity, 4)atmosphere. On the basis of the results, a questionnaire consisting of 16 items related to the above four factors was constructed as an instrument to assess pupils' consciousness about their classroom.
