Abstract
The purpose of this study is to compare the use of number of links and sum of weight for measuring the level of participations among students in online discussion. Usually, SNA determines the level of participation in asynchronous online discussions based on number of links. However, it is not fair for participants who send or post a message more than once. The effectiveness of these two approaches are measured and then statistically compared based on social network indicators; degree, degree centrality, density and network degree centralization. The result shows that sum of weight is more appropriate, reliable and objective than number of links to measure the level of participation among students in online discussion.
