Effective anchors are intrinsically interesting, fostering ownership, and help students notice the features of problem situations that make particular actions relevant (Bransford et al., 1990, p. 123). The CTGV (1991) uses the following design principles when creating anchored instruction. First, they use a video-based presentation format because of the dramatic power of the medium and because of the use of multiple modalities, realistic imagery, and omnipresence in our culture. Second, they present a problem using actors and a narrative format for interest. Third, the problem solution requires a generative learning format in which students must identify pertinent information in the fourth feature, embedded data design. Fifth, the problem is complex with the possibility of multiple solutions and perspectives and requiring a team approach. Sixth, they use pairs of similar problems in different contexts to enrich the indexicalization of knowledge structures. Finally, they attempt to draw links across the curriculum to enhance the relevance of the problem.
