A GUIDE TO PORTFOLIO ASSESSMENT IN SECONDARY MATHEMATICS CLASSES By Michael Buzbee Summer 2004 The purpose of the project was to develop of clear, useful, and helpful teacher handbook for incorporating portfolios in secondary mathematics classes. By providing an assortment of classroom ideas, activities, and suggestions that complement portfolios, the design of the handbook was intended to help minimize the frustrations that seem to arise when teachers attempt something “new and different.” The strategies for developing portfolio assessment in the handbook support constructivist philosophy and curriculum, and are designed to most mathematics education settings. Activity templates with suggestions are provided throughout the handbook. Questionnaire data was collected from eight teachers with experience teaching secondary mathematics. The teachers were asked to rate, and comment on the helpfulness and clarity of the handbook. Responses to the questionnaire also provided information as to ways in which the handbook could be improved. The overall response from teachers was that the handbook was clear and helpful.
