This four-part report discusses the planning of modules through the use of a matrix and contains two case studies as illustration. Part 1, "Applying the Matrix to an Existing Course Outline," shows how to analyze a course outline, adapt it to a matrix, and plan appropriate modules. Part 2, "Matrix Analysis," examines the matrix in order to discover its potential use for course development. Part 3, "Paragraph Format: Fundamentals of Nursing: (Overview)" presents an example of well-developed course material that can be used as the starting point for a matrix. Part 4, "Matrix Format: Fundamentals of Nursing: (Overview)" shows how material that previously appeared in paragraph format can be translated with minimum effort and time into matrix format.
