Five Degrees of Happiness: Effective Smiley Face Likert Scales for Evaluating with Children

This paper focuses on achieving optimal responses through supporting children's judgements, using Smiley Face Likert scales as a rating scale for quantitative questions in evaluations. It highlights the need to provide appropriate methods for children to communicate judgements, highlighting that the traditional Smiley Face Likert scale does not provide an appropriate method. The paper outlines a range of studies, identifying that to achieve differentiated data and full use of rating scales by children that faces with positive emotions should be used within Smiley Face Likert scales. The proposed rating method, the Five Degrees of Happiness Smiley Face Likert scale, was used in a large-scale summative evaluation of a Serious Game resulting in variance within and between children, with all points of the scale used.
