No results posted yet for this study

Summary

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.

Contextual variation

The participants are instructed to perform ultrasound guided needle puncture of the cavities using a 20 ml syringe and a 15 cm, 18 Gauge biopsy needle. When all the three cavities are emptied the participant receive a new cube with refilled balloons. The new cube is equivalent to the old apart from being rotated 180 degrees. The participant are given one hour to empty as many cavities as possible. They are encouraged to track the needle with ultrasound while in the cube. The transfer test is performed on a CVS mannikin. The GE HealthCare LOGIQTM e Ultrasound is used with a C1-5 RS probe with or without the GE HealthCare C1-5 non-sterile ultrasound needle guide for both the training session and the transfer tests.
