Assessment of genetics knowledge and skills in medical students: Insight for a clinical neurogenetics curriculum
Authors: Pearl Phillip L. , Pettiford Jennifer M. , Combs Susan E. , Heffron Ari , Healton Sean , Hovaguimian Alexandra , Macri Charles J.
Published: June 2011

The pace of discovery in biochemistry and genetics and its effect on clinical medicine places new curricular challenges in medical school education. We sought to evaluate students' understanding of neurogenetics and its clinical applications to design a pilot curriculum into the clinical neurology clerkship. We utilized a needs assessment and a written examination to evaluate the genetics knowledge of 81 third‐ and fourth‐year medical students. The needs assessment surveyed students' self‐perceptions of their own understanding of basic and clinically related genetic principles and clinical skills, as well as the most effective educational methods. Medical students reported more competence with basic science learned during the preclinical years than clinical concepts, and they demonstrated relatively low knowledge levels in clinical neurogenetics concepts on the examination, with an average of 29% correct on questions pertaining to genetic counseling compared with 82% correct with regard to inheritance patterns. Common, cross‐specialty clinical skills were attained (e.g. internet search, family histories), while at least half of students reported minimal understanding or awareness of key genetics websites (e.g. OMIM) and indications for support group recommendations and genetics referrals. Teaching these more specific genetics skills and concepts needs to be emphasized in the clinical curriculum. BIOCHEMISTRY AND MOLECULAR BIOLOGY EDUCATION Vol. 39, No. 3, pp. 191–195, 2011.
Teaching argumentation and scientific discourse using the ribosomal peptidyl transferase reaction
Authors: Johnson R. Jeremy
Published: June 2011

Argumentation and discourse are two integral parts of scientific investigation that are often overlooked in undergraduate science education. To address this limitation, the story of peptide bond formation by the ribosome can be used to illustrate the importance of evidence, claims, arguments, and counterarguments in scientific discourse. With the determination of the first structure of the large ribosomal subunit bound to a transition state inhibitor came an initial hypothesis about the role of the ribosome in peptide bond formation. This initial hypothesis was based on a few central assumptions about the transition state mimic and acid–base catalysis by serine proteases. The initial proposed mechanism started a flurry of scientific discourse in experimental articles and commentaries that tested the validity of the initial proposed mechanism. Using this civil argumentation as a guide, class discussions, assignments, and a debate were designed that allow students to analyze and question the claims and evidence about the mechanism of peptide bond synthesis. In the end, students develop a sense of critical skepticism, and an understanding of scientific discourse, while learning about the current consensus mechanism for peptide bond synthesis.
