In the era of the Internet, factors which influence effective learning in a Web-based learning environment are well worth exploring. In addition to knowledge acquisition and skills training, affect is also an important factor, since successful learning requires excellent affective performance. Thus this study focuses on learners' affective performance in Web-based learning. An initial description of the personality traits relating to entrepreneurship and Web-based learning was formulated and then examined with a Delphi survey. The findings show that certain personality traits relating to entrepreneurship are also associated with successful learning in Web-based learning. This study identified four dimensions and ten components which together constitute the metaphor of entrepreneurship in Web-based learning. (Contains 3 tables and 1 figure.)
