This study aims to apply Unplugged Programming Games teaching and learning activities to understand the result of cognitive learning outcomes. The child was five years old with developmental delays. A multiple probes design across behaviors of single-subject experiment design was implemented. The independent variable was, and the dependent variables were the immediate result of cognitive learning outcomes, the maintain results of cognitive learning outcomes and the reaction of teacher’s attitude toward the intervention of Unplugged Programming Games teaching. In this study, visual analysis, C statistical and social validity analysis were used to explore the experimental results and to understand the effectiveness of their teaching. Attributed to the conclusion of this study, the result is as following: Applying Unplugged Programming Games teaching on the children with developmental delay can observably increase the ability. After Unplugged Programming Games teaching has been applied to the participant, the improvement in the cognitive ability of children with developmental delay can remain good performance and social validity analysis. Base on the conclusion described above, the study may provide some teaching advice for future studies.
