This research used vicarious-learning procedures in an attempt to increase students’ knowledge of the domain and enhance the quality of their questions in an intelligent tutoringsystem involving computer-controlled animated agents. Students who overheard a dialogue in which a virtual tutee asked a virtual tutor questions during acquisition wrote significantly more in free recall and asked signi...

Concept mapping has been used in multiple research domains for a variety of purposes such as brainstorming, knowledge elicitation, student testing and evaluation. Our work has applied the technique with pilots, emergency managers, emergency responders, and image analysts. Indeed, concept mapping has proven to be valuable both as an end state to represent and in turn understand knowledge, as wel...

The main objective of the LKC approach (Learning by Knowledge Construction [Rouane, Frasson and Kaltenbach 2002]) is to provide an effective support for a student’s reading activity in a learning context while promoting and facilitating his understanding and knowledge acquisition. This paper shows how active reading can be supported and sustained with the use of advance annotation approach of t...

The attribute reduction is one of key processes for knowledge acquisition. This paper deals with approximate approach to attribute reduction. The concept of minimal discernible attributes set is introduced and a calculation method for it is investigated. And then, the judgment theorem with respect to keeping positive region invariability is obtained, from which an approximate approach to attrib...

This research uses Huber’s (1991) conceptualization of organizational learning to analyze knowledge acquisition by management teams in emerging firms. Involvement in ongoing knowledge acquisition activities is positively and significantly related to new venture performance. In addition, task environment dynamism is a positive moderator of the relationship between involvement in knowledge acquis...

This paper examines the impacts of the knowledge transfer capacity of multinational enterprises (MNEs) on the extent to which international joint ventures (IJVs) acquire technology. Although MNEs’ capability to transfer knowledge is a key catalyst for IJVs to learn new information, extant literature currently sheds light on only student’s absorptive capacity and neglects teacher’s fundamental a...

The development of knowledge-based systems (KBS) enables accumulated experience and knowledge to be applied to the intelligent monitoring in the field of large-scale belt conveyor systems. The first step of building knowledge bases in a KBS is referred to the knowledge acquisition (KA). KA from domain experts and field experiments has often been considered as the most difficult task and time-co...

A knowledge service-oriented business has not been highly progressed because most of potential users do not expect much on it by chronic feeling of disappointment about conventional strategy of knowledge management. Since the approaches to manage and utilize knowledge within an organization were identically split into one of knowledge acquisition and distribution, few practical ways providing k...
