Different types of adapting learning materials include the quantity and quality of material available; the expertise of those adapting the material; the course delivery format and length; and whether the material has been sourced from another region. According to Phil Race in the Open Learning Handbook, writing a course could take ten hours for each hour of instruction.
Recent survey says, this author conducted a Canada-based survey that found the cost of preparing an online distance course based on lecture-based material was about one-third less than preparing the course from scratch, and that it took six to nine months to produce a distance course by adapting existing materials. Using nteractive learning objects from a learning object repository (LOR) reduced course development time, yet produced an interactive and engaging course. If there was extensive media use, such as video, animations and simulations, it took up to two years to produce a quality course. The less media material involved, the shorter the adaptation time, but the resulting course material had less interactivity—a key ingredient of quality courses.
