Curriculum development and course design involve 5 major tasks: 1) assessing learner needs, 2) deciding objectives, 3) selecting learning experiences, 4) determining appropriate methodologies/resources, and 5) evaluating effectiveness. Key aspects of the process include determining measurable objectives, using a variety of instructional methods to achieve objectives, and evaluating learner behavior changes over time through methods like tests and observations. The overall goal is to design a curriculum and courses that meet learner needs through clear objectives and engaging learning experiences.
