Three Dimensional Structure Model of Teachers' Information Needs with Different Information Interaction Styles

Abstract

As an organic whole with certain external connection and internal structure, information demand is restricted by social factors as well as individual factors because of its special stipulation. Under the combined action of different factors, the structure of information demand presents a dynamic changing process and various basic states. Different forms of information interaction style model and information requirement model are determined. According to this complex representation, a three-dimensional structure model is presented. On the basis of this model, the correlation among information requirement process stage, cognition and emotion is studied. The experimental results show that information requirement is excessive. The reliability and validity of the model are very high among process stage, cognition and emotion, and the result of the model is compared with the result of expert evaluation. The result of analysis is almost the same as that of expert analysis, which indicates that the three-dimensional structure model of teachers' information needs with different information interaction styles has certain application performance.
