Posner and Strike (1976) suggested three sequencing strategies based on how objects or events appear in the real world, concepts and their relationships to other concepts, and the interests and needs of the learner. Organizing the content according to one of these schemes provides a systematic method for presenting the content that is likely to match the learner's expectations. Select all that applies to the sequencing strategies. Collaboration theory sequence content based on whether the learner is developing task expertise or concept expertise. Concept expertise sequencing presents the logical relationship between the concepts or presents the content in a sequence similar to what one might have used to discover the idea. Task expertise sequencing proceeds from the simplest to the more complex tasks
