A quasi-experimental design was employed and a total of 134 eighth graders participated in the experimental activity. The independent variables included types of scaffolding (concept scaffolding vs. procedure scaffolding), prompting (video prompting vs. picture prompting), and prior knowledge (high vs. low). The dependent variables were students’ learning performance and motivation. The results revealed that: (a) for the comprehension performance, the high prior knowledge group outperformed the low prior knowledge group; (b) for the application performance, the interaction between scaffolding and prompting is significant, the video prompting group outperformed picture prompting group while receiving procedure scaffolding; and the concept scaffolding group outperformed procedure scaffolding group while using picture prompting; the high prior knowledge group outperformed the low prior knowledge group; and (c) all participants showed positive motivation toward programming learning, and particularly, the concept scaffolding group showed higher degree of motivation than the procedure scaffolding group did.鷹架策略提示策略先備知識程式設計機器人scafflodingpromptingprior knowledgeprogrammingrobot
