While researchers have often sought to understand the learning curve in terms of multiple component processes, few studies have measured and mathematically modeled these processes on a complex task. In particular, there remains a need to reconcile how abrupt changes in strategy use can co-occur with gradual changes in task completion time. Thus,…

Recently, technology-supported formative assessment has caught researchers' increasing attention. Most of the relevant studies have been carried out in experimental situations to demonstrate the effectiveness of technology-supported formative assessment for learning. However, little is still known about how technology-supported formative…
