简要总结
The goal of this randomized study is to investigate the effect of introducing contextual variation on transfer when learning a technical skill in a group of medical students. The main questions it aims to answer is: If context variation of specific affordance conditions enhance the learner's ability to transfer out? Participants will practice performing an invasive ultrasound guided procedure either on a fantom with maximum affordances or with contextual variation. Researchers will compare the maximum affordances group and the contextual variation group to see if its effects compared to the control group with minimal affordances.
详细描述
Participants:
Participants are medical student from the University of Copenhagen. They are recruited by announcements on student fora on Facebook.
Randomization:
The participants are randomized to the intervention group contextual variation, the intervention group maximum affordances or control group minimum affordances in an 1:1:1 allocation ratio. In addition, the order of the four transfer tests (a, b, c and d) is randomly selected for each participant. The randomization was conducted by an independent research assistant at CAMES. Random permuted blocks are generated online for both the intervention and the transfer test.

研究组 & 干预措施
Contextual variation
The contextual variation group alternate between six affordance conditions where the surface of the model i either half covered combined with no guide, a partial guide or a complete guide.
干预措施: Contextual variation (Other)
Maximum affordances
The maximum affordances group has half the surface model covered and a complete guide throughout the session.
干预措施: Maximum affordances (Other)
Minimum affordances
The control group has the whole surface uncovered and no guide throughout the session.
