It should be noted that to the extent that the two external representations yield identical outcomes, the design does not allow these effects to be disentangled from the overall influence of the group exercise.
This design was used to allow any differences in outcome between using the two external representations in the group exercise to be revealed.
Although the two external representations required slight variations in the guide (e.g., see task 1 above), the ambition was to treat both groups identically.
Because two very different external representations of self-assembly were used, it is possible to discuss the observed qualitative differences between students in the two conditions in terms of the properties of the representations.
Recent releases like Create ML are external representations of the work that Apple's ML teams are doing internally, but that work is still too fragmented.
In any reputable news organization, the content produced by journalists serves as an external representation of the company's values and opinions.
The differences in the impact of using two different external representations (a tangible model and an image) on learning about self-assembly in a group exercise were investigated using a true experiment design (Robson, 2002).
Two different external representations were selected for this study, namely a tangible model and an image, both of which show the self-assembly of a virus capsid.
The two different external representations (i.e., the tangible model and the image) were used as focus instruments in group exercises.
In particular, when information from the two sources does not match well, external representations hinder instead of enhance task performance.
