Teachable agents are pedagogical agents based on the concept of learning-by-teaching. Persuasion theory enhances the capabilities of teachable agents by influencing positive attitude change in learners. This paper proposes Persuasive Teachable Agent (PTA) that enables the selection of persuasive strategies based on persuasion theory to improve learning attitudes. In a preliminary study involving PTA, learners were observed to display increased interest in engaging in learning activities with the teachable agent.
