This document describes a distance learning course on quality in international horticultural production chains offered by Wageningen University. It discusses the course design which includes an orientation period, acquiring content through lectures, internalizing the material in problem-based learning groups, providing feedback through video conferencing and email, examining students with a final product, and evaluating the course and students.
