The learning activities model (LAM) developed in the previous chapter provides a theoretical framework for the analysis of the process of learning through the categorization of activities. During the design of learning events, different techniques, methods, and technologies can be applied to activities within each category or to complete categories of the LAM. This matching process is, in essence, the basis of the technology selection method (TSM), presented in Chapter VIII. However, before technologies that are appropriate to learners and learning events can be selected it is essential to have a clear understanding of the nature and capabilities of the technologies. To assist in the understanding and analysis of learning technologies, a theoretical framework of them, called the learning technologies model (LTM), is presented.
