ID and ISD Models The main goal of an ID (Instructional Design) model or process is to construct a learning environment in order to provide the learners with the conditions that support the desired learning processes. ID models differ from an ISD (Instructional System Design) model in that ISD models are more broad in nature. On the other hand, ID models are less broad in scope and normally focus on the first two phases of the ISD model - analysis and design. They focus on the analysis of a to-be-trained skill or knowledge-acquisition and then convert the analysis into a training strategy (design of the learning environment).
While ID models normally only account for analysis and design, ISD models normally cover five-phases: Analysis Design Development or Production Implementation or Delivery Evaluations. Formative and Summative Evaluations. The Business Model Canvas - A Powerful Tool. Alex Osterwalder, an author, speaker and consultant on business model innovation has developed a powerful tool to describe business models in a structured, simplified and understandable way. This was, together with an overview and synthesis of existing literature about business models, perhaps the main contribution with his dissertation on business models in 2004.
It is also the basis for the beautiful book he is currently finalizing on the subject. Creating a common understanding A very valid point Osterwalder makes, that also Linder and Cantrall made in 2000, when discussing the confusion related to the concept of business models, is that many people speak about business models when they only mean parts of a business model. By having a common understanding, and a visual representation, the users of the canvas can easily separate what parts are being discussed and relate it to the overall picture. 9 elements mentioned by at least two other authors Visual thinking. Models of Models. Written for Interactions magazine by Hugh Dubberly. Models are ideas about the world—how it might be organized and how it might work. Models describe relationships: parts that make up wholes; structures that bind them; and how parts behave in relation to one another.
Models are ideas about the world— how it might be organized and how it might work. For example, the sun rises in the east, moves across the sky, and sets in the west. A representation of the Ptolemaic model of the “world system” — a geo-centric view. A representation of the Copernican model of the “solar system” — a helio-centric view. Making Sense and Guiding Action Models help us make sense of things. Observations can be a source of new models. Models are conjectures—hypotheses. Chris Argyris wrote, “Although people do not [always] behave congruently with their espoused theories [what they say], they do behave congruently with their theories-in-use [their mental models].” [4] Under this frame, models lead to action.
