A series of short courses was presented on various aspects of curriculum practice to enable teachers to review and reconsider established practices, to acquire knowledge of recent and impending developments, and to gain experience in the techniques involved. This collection of rewritten versions of lectures given at these classes is divided into two parts. Three sections in the first part focus on objectives, assessments, and activity-based learning situations, while the final section is an effort to reconcile the problems of preparing worthwhile objectives relating to transferable mental skills and personal qualities with the need to make valid assessments. The second part provides examples, based on teacher ideas and experiences, of activity-based teaching-learning situations demonstrating the implementation of the principles discussed. (Author/CMV)
