Scaffolding of Thinking about Structure with Kit-Building Task

Abstract

In this paper, we introduced interactive environment for "learning by problem-posing" in arithmetic word problems. This problem-posing task is designed based on a structure model of arithmetic word problem and the task is realized by selection and combination task of provided sentences. This research expects that a learner is promoted to think about structure of arithmetic word problem through the activity of the problem-posing. We call this task "kit-building task". We think that design "kit-building task" based on "structure model" is a promising approach to realize promotion "thinking about structure". In this paper, we introduce learning by problem-posing as an example Of this approach. Through presentation and discussion about this approach in TELoTS, we would like to make clear the relation between "Thinkin Skills" and this research.
