The efficacy of peer assessment in objective structured clinical examinations for formative feedback: a preliminary study

Abstract

We sought to determine the impact of medical students' prior experience of assessing peers in the objective structured clinical examination (OSCE) on their clinical performance. Forty-two year 4 medical students participated in an OSCE comprised of three 10-minute stations (syncope, hemoptysis, and back pain). Each student took part in two iterations of the three-station OSCE as either the examiner or examinee, and student performance was assessed using a checklist by a medical faculty member and a student simultaneously. Students were randomly assigned to two groups and their OSCE scores were compared. Students in the control group were tested at a station first and then participated at the same station as a peer examiner, and those in the intervention group participated as a peer examiner first and then as an examinee. Moreover, student OSCE scores rated by peer examiners were compared with those awarded by faculty to evaluate the accuracy of peer assessment. Following the test, students completed surveys on their perceptions of the usefulness of this formative OSCE. Student overall OSCE scores did not differ between groups. Students in the study group performed better at the hemoptysis station (p<0.001), but poorer at the...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
