Adaptive learning techniques have typically scheduled practice using learners' accuracy and item presentation history. We describe an adaptive learning system (Adaptive Response Time Based Sequencing--ARTS) that uses both accuracy and response time (RT) as direct inputs into sequencing. Response times are used to assess learning strength and to…

Compared the effects of constructivist instruction and instruction based on texts and demonstration on third-graders' conceptualization of force. Found that constructivist instruction was more effective. Patterns of reasoning related to force were identified in levels of conceptualization. (JPB)
