were five experts who gave comments to the developed materials. They were two experts of materials of English For Children and
three Elementary English teachers. There were three steps conducted to show the reliability of the questionnaire. First, the
questionnaire was administrated to the experts. There are 5 possible points; 5 points for Strongly Agree SA, 4 points for
Agree A, 3 points for Neutral N, 2 points for Disagree DA, and 1 point for Strongly Disagree SA. Second, the questionnaires
were recapitulated after all the questionnaires were given back to the researcher. Third, the Alpha Cronbach formula was used to find
the reliability coefficient of the questionnaire.
3. Third Questionnaire
The third questionnaire was administrated to the students after the implementation of the developed materials. It was aimed at finding
students’ opinions about the developed materials. There were 20 questions in the questionnaire.
a. Validity For the validity measures, the researcher used construct
validity. To obtain the construct validity, the researcher consulted the outline of the questionnaire to the first supervisor

students’ profile, the relation between the goals of the developed materials and students’ needs, the contents of the
developed materials, the varieties of the tasks and activities, the clarity of the instructions, and the general layoutof the
developed materials Nunan, 2004; Harmer, 2001; Brown, 2001. Here below is the organization of the third

the questionnaire. First, the questionnaire was administrated to 23 students as the subject of the study. There are 5 possible
points; 5 points for Strongly Agree SA, 4 points for Agree A, 3 points for Neutral N, 2 points for Disagree DA, and 1
point for Strongly Disagree SA. Second, the questionnaires were recapitulated after all the questionnaires were given back
