Randomized Experiments

Randomized Experiments

The randomization process involves assigning study participants randomly to experimental or control groups based on their probability of being equally assigned. Randomization is meant to eliminate selection bias and balance known and unknown confounding factors so that the control group is similar to the treatment group as much as possible. A computer program and a random number generator can be used to assign participants to groups in a way that minimizes bias.

Area of Science:

Medical Education
Pedagogy
Clinical Skills Assessment

Background:

Near-peer teaching offers benefits but its impact on academic attainment is unclear.
Existing models lack clarity on translating to student performance.
A novel near-peer teaching model was developed to address these gaps.

Purpose of the Study:

To pilot a novel near-peer teaching model in a formative Objective Structured Clinical Examination (OSCE) setting.
To assess the feasibility and acceptability of the new teaching model.
To gather descriptive outcomes to inform the design of a larger study.

Main Methods:

A pilot study involving 22 pre-clinical medical students in an OSCE setting.
Random assignment to intervention (near-peer teaching) or control (self-regulated practice) groups.
Formative OSCE assessments with structured teaching or self-regulated practice, followed by re-assessment.

Main Results:

Students in the teaching group gained an average of 3 additional marks.
Both students and tutors reported increased confidence and satisfaction.
Evidence of reflective practice was observed among participants.

Conclusions:

The novel near-peer teaching model demonstrated feasibility and acceptability.
Descriptive outcomes support the need for a larger, powered study.
Further research is required to confirm the model's impact on summative exam performance.
