Lynch and Purnawarman (2004:50) point out that "a solid electronic portfolio can show reflection, evolution of thought and overall professional development". Research shows that electronic portfolio assessment, if implemented thoughtfully, can successfully engage learners in critical thinking and problem solving, promote lifelong education, encourage self evaluation and allow learners to have a higher degree of control over the learning process (Pierson and Kumari, 2000; Mason, Pegler, and Weller, 2004). Given the value of electronic portfolios, there has been growing interest in using electronic portfolio assessment to support teacher education (Lynch and Purnawarman, 2004). In this paper, we discuss on-going efforts at the University of Hong Kong to design assessment tasks for a language awareness course entitled "Pedagogical Content Knowledge". The final-year student teachers taking the course are required to compile an electronic portfolio based on their reflections on the relevance and applicability of the issues relating to dealing with the content of learning in pedagogical practice discussed in the course. This paper sets out to describe and analyze issues relating to the design and implementation of the assessment, focusing specifically on the challenges that the research team faces. In our paper, we draw on a range of data, including student teachers' feedback on the assessment and in-depth reflections of two student teachers after the assessment to critically evaluate the extent to which the assessment has achieved the intended learning outcomes. The reflective study shows that apart from technical support, methodological and psychological preparation designed to help students to take on a more active role in the learning and assessment process are also needed to help students to perform effectively in the computer-supported assessment. Implications are drawn for those who plan to conduct electronic portfolio assessment in higher education.

Despite emphasis and progress in developing collaborative inquiry in computer-supported collaborative learning research, little attention has been given to examining how collective learning can be assessed in computer-supported collaborative learning classrooms, and how students can have agency in assessing their own collaborative process. We propose that assessments should capture both individual and collective aspects of learning and be designed in ways that foster collaboration. We describe the design of student-directed electronic portfolio assessments to characterize and "scaffold" collaborative inquiry using Knowledge Forum™. Our design involved asking students to identify exemplary notes in the computer discourse depicting knowledge building episodes using four knowledge building principles as criteria. We report three studies that examined the designs and roles of knowledge building portfolios with graduate and Grade 12 students in Hong Kong and Canada. The findings suggest that knowledge building portfolios help to characterize collective knowledge advances and foster domain understanding. We discuss lessons learned regarding how knowledge building may be fostered and provide principles for designing assessments that can be used to evaluate and foster deep inquiry in asynchronous online discussion environments.
