As part of an ongoing effort to understand the processes people employ in reading technical material and the ways in which computer based job aids can assist people in doing complex tasks, a study was conducted to determine how subjects engaged in an assembly task use a detailed and hierarchically organized information structure (Hypertext) to…

The purpose of this study is to contribute to an understanding of how errors could be employed in mathematics instruction so that the students use them constructively in support of their learning of mathematics. A teaching experiment was designed to create an ideal context in which the pedagogical approach to errors as springboards could be…
