The purpose of this study was to develop an intellectual humility scale in elementary science education. To achieve this goal, a preliminary survey of 11 teachers and a main survey of 791 elementary school students were conducted to examine the factor structure of intellectual humility in science. As a result, we were able to develop two versions of the scale, a full version and a short version, consisting of the 3 factor structures of “open mindedness,” “prudence toward generalization,” and “independence of intellect and ego”.
