This interpretive study of the implementation of a school-based assessment scheme of biology practical work in Hong Kong examines three teachers' struggles with the issue of fairness in relation to their classroom actions. Though the teachers' discourses were dominated by, and their classroom actions were pre-eminently influenced by, the notion of fairness, they did so in three qualitatively different ways: (1) fair in the sense of assessing students on a fair basis; (2) fair in the sense of not jeopardizing students' chances to learn the subject matter while they are being assessed; and (3) fair in the sense of not depriving students' of opportunities of receiving all-round education. The implication is that assessment innovation is a necessary, but not a sufficient, mechanism for changes within our educational system. The role of the teacher is challenged by the new assessment scheme—the co-existence of assessment and learning requires a significant change in the teacher's pedagogy. For teachers to implement the new programme their existing understanding and beliefs concerning assessment must be challenged and opportunities provided for them to come to terms with the philosophy of the new assessment scheme. Most importantly, the teachers themselves must undertake such a learning process.

This article is based on the findings of a study that examined the use of portfolios for assessment and learning purposes in an initial teacher education course in the Hong Kong Institute of Education. Progressive refocusing of the research led to an investigation of the extent to which the use of portfolios for such purposes promoted the development of reflective practice and teaching skills. Constraints and supports for the implementation of portfolios were identified through the use of observation, documentary analysis, surveys, video recordings and interviews with pre-service teachers and their lecturers. The implementation process and the teaching and learning outcomes are described. Teacher educators requested portfolio exemplars, more specific grading criteria and more examples to illustrate standards. Six principles that underpin the use of portfolios for assessment purposes, that emerged from an analysis of the research data and findings, are briefly described. An interactive CD ROM and a set of guidelines were produced as implementation resources. Details of these resources are provided.
