While "mobile learning" has gained recognition in K-12 as a category in educational technology, the authors argue that, between 2010 and 2015, at least, its impact hasn't matched the hype. But between 2015 and 2020, hardware, software, and network technologies will mature sufficiently such that educational technology's Holy…

Evaluates the scaffold designed as a dynamic modeling software tool called Model-It in terms of its ability to support learners' use of modeling practices. Discusses the continued empirical validation of types and instances of tool scaffolds. (Contains 50 references.) (Author/YDS)

The notion of scaffolding learners to help them succeed in solving problems otherwise too difficult for them is an important idea that has extended into the design of scaffolded software tools for learners. However, although there is a growing body of work on scaffolded tools, scaffold design, and the impact of scaffolding, the field has not yet…

If learners are to engage in science inquiry, they need significant support, or scaffolding, to help them mindfully do the cognitive science tasks that are just out of their reach. One approach for supporting learners is to design computational tools that incorporate scaffolding features to make new practices accessible and visible so learners can…
