Using item response theory to explore the psychometric properties of extended matching questions examination in undergraduate medical education [PDF]
BACKGROUND: As assessment has been shown to direct learning, it is critical that the examinations developed to test clinical competence in medical undergraduates are valid and reliable. The use of extended matching questions (EMQ) has been advocated to

Ein Mangan‐Einzelatom‐Photokatalysator auf funktionalisiertem Kohlenstoffnitrid ermöglicht die selektive, durch sichtbares Licht angetriebene C(sp2)–H‐Chlorierung. DFT‐gestützte mechanistische Untersuchungen zeigen, dass die photoinduzierte Ladungstrennung NCS aktiviert, während isolierte Mn‐Zentren Mn–Cl‐Intermediate an der Katalysatorgrenzfläche ...

A Penalty Approach to Differential Item Functioning in Rasch Models [PDF]
A new diagnostic tool for the identification of differential item functioning (DIF) is proposed. Classical approaches to DIF allow to consider only few subpopulations like ethnic groups when investigating if the solution of items depends on the ...

Lichtaktivierbare Iridium(III)‐Prodrugs zeigen, wie die Koordination von Chalkogenen die photoinduzierte therapeutische Aktivität steuert. Bei Bestrahlung mit sichtbarem Licht laufen an den schwefel‐ bzw. selenhaltigen Liganden unterschiedliche, sauerstoffabhängige Photoreaktionen ab.
