An Attempt to Develop a Questionnaire for Measuring the Effectiveness of Comment Cards

Focusing on questioning skills as a component of critical thinking, this study examined a common classroom practice for developing these skills in students: comment cards. The purpose of this study was to develop a questionnaire that measures the effectiveness of comment cards by describing how students use them and what ideas and attitudes they foster among students.
　A survey was conducted with 108 participants, making use of 15 question items regarding how teachers intended to use comment cards in classes and how the students responded. A factor analysis yielded 11 items divided into three factors . After testing the reliability of the model, a final version of the scale (the Scale for Measuring Effectiveness of Comment Cards) was produced.
　The scale can provide researchers with a quantitative measure for examining the practical effectiveness of comment cards. When used in combination with scales on critical thinking and questioning, the scale can further provide insights into both the practical effectiveness of comment cards and the issues to be addressed.
