Collaborated learning management tools (CLMT) were used as part of the teaching and assessment process with a cohort
of computer science students from three universities in Ireland, England and the USA in the area of professional issues
(the legal, ethical and social aspects of computing). Students in the cohort used asynchronous communication tools to
work in virtual groups to solve a moral/legal dilemma case study. They were originally assessed on a written report
based on the content of their postings to a discussion board. Subsequently a framework for the assessment of critical
thinking developed by Anderson et al (2001) was used to analyse the discussion threads produced by the same learners.
This paper describes the naauter of this study, discusses the use of computer-mediated communication (CMC) in the
teaching and assessment of professional issues and reflects on the possible links between the use of CLMT in a
collaborative learning situation and the development of higher order critical thinking skills in tertiary level students.
