Developing a Web assisted knowledge construction system based on the approach of constructivist knowledge analysis of tasks

摘要

The purpose of this study is to develop a Web assisted knowledge construction (WAKC) system as an individual knowledge construction tool for Internet users. The system is based on the theory of constructivist knowledge analysis of tasks (CKAT). The CKAT integrates constructivist reflection cycle and knowledge analysis of tasks. The conceptual model of CKAT includes four different stages: knowledge objective, knowledge gathering, knowledge analysis, and task knowledge structure. In order to match these four stages, this research designs an assisted knowledge construction system that includes four systematic sub-functions: the keyword function, the URL resource function, the analysis function, and the construction function. After understanding users' perceptions toward the WAKC system, users have highly positive behavioral intention to use the system as a Web-based assisted knowledge construction tool.
