Brief 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.

Outcome Measures

Primary Outcomes (1)

• Transfertest score

  Exåpert based performances scores using a 5 point likert scale rating 4 items. Higher scores indicate better performance.

  4*7 min (4 tests) 7-10 days after intervention

Secondary Outcomes (1)

• Training

  60 min (training session)

Study Arms (3)

Contextual variation

EXPERIMENTAL

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.

Other: Contextual variation

Maximum affordances

EXPERIMENTAL

The maximum affordances group has half the surface model covered and a complete guide throughout the session.

Other: Maximum affordances

Minimum affordances

NO INTERVENTION

The control group has the whole surface uncovered and no guide throughout the session.

Interventions

Contextual variation OTHER

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.
