Computer-supported collaborative learning has become one of the important areas in the education and training field, and online discussion is the predominant mode in the meaning-making process. While many of the software available in online discussion are text-based, recent development in such tools includes the capability of viewing video. This chapter introduces the use of software that allows users to engage in collaborative discussion by attaching notes to video footage. This type of software is relatively new in education applications. This chapter also reports findings from the study and suggests how such tool can be applied to improve the interaction among learners in other training situations in computer-supported learning environments.
