In the last few years there has been a proliferation of asynchronous online discussion forums which have opened up the possibilities for people to exchange ideas at any place and at any time. The literature has documented that asynchronous online discussion has the following desirable characteristics: 1) it may help enhance the participation of students who might be less willing to participate in traditional face-to-face classroom settings due to shyness; and 2) it has the potential to encourage more thoughtful responses since participants can take their own time in composing their thoughts. Nonetheless, despite the promise of asynchronous online discussion to promote rich learning experiences, students do not always make use of its potential. The purpose of this study was to examine how a group of Singapore students interacted with one another, as well as the types of thinking skills, critical or creative thinking, and levels of information processing they exhibited during an asynchronous online discussion. This was an attempt to develop certain guidelines that would help facilitate students' in-depth thinking and promote student-to-student interaction in an online discussion environment.*
AN EQUIVALENCE FORM OF THE BRUNN-MINKOWSKI INEQUALITY FOR VOLUME DIFFERENCES
Zhao, Chang-Jian,Cheung, Wing-Sum Korean Mathematical Society 2007 대한수학회지 Vol.44 No.6
In this paper, we establish an equivalence form of the Brunn-Minkowski inequality for volume differences. As an application, we obtain a general and strengthened form of the dual $Kneser-S\ddot{u}ss$ inequality.
ON OPIAL INEQUALITIES INVOLVING HIGHER ORDER DERIVATIVES
Zhao, Chang-Jian,Cheung, Wing-Sum Korean Mathematical Society 2012 대한수학회보 Vol.49 No.6
In the present paper we establish some new Opial-type inequalities involving higher order partial derivatives. The results in special cases yield some of the recent results on Opial's inequality and provide new estimates on inequalities of this type.

A Framework for Enculturating Thinking Dispositions
Chin Ee Neo,Wing Sum Cheung 대한사고개발학회 2007 The International Journal of Creativity & Problem Vol.17 No.2
Studies have shown that students who possess good thinking dispositions tend to do well academically thus there arises a need to help students cultivate these think-ing dispositions. Although research has suggested activities that may enculturate thinking dispositions, no framework to date has been suggested to help teachers do so in the classroom. This paper attempts to explore the tools, roles and rules based on available literature that may help to enculturate thinking dispositions using ac-tivity theory as the framework.
