Dental and Maxillofacial Radiology Dental Specialty Specialise in radiology of teeth, jaws and adjacent structures
Concerns with paper exams Lack of consistency in marking Feedback from candidates Inability to include actual radiographs The task of marking
October 2006 Attended a study day organised by the University of Dundee focused on Education Presentation by Dr David Walker on e-learning and assessment Started a discussion about piloting online version of examination
Disadvantages of electronic format Considerable amount of work to set up No free text Some questions are difficult to transfer to this format
Colleague concerns Is it easier? – answer in front of candidate Exam shorter (1 hour on computer; 2 hours on paper) Is understanding being assessed?
Radiological anatomy and quality assessments – can use real images not line diagrams
Drag and Drop not previously possible This is a periapical radiograph of maxillary molars and premolars. From the selection of words below, drag and drop the correct label to identify the radiographic feature: Enamel Caries Dentine Zygoma Pulp Nasal cavity Maxillary sinus Calculus
Ways around inability to draw In this question, the blue line represents dental radiographic film and the yellow lines the incident X-ray beam. Select the diagram which demonstrates the relationship of the tooth, beam and film for bisecting angle periapical radiograph.
Whats happening now? First exam was in February 2009 Examination + resit every year (100 students / year) Continuous evolution – try and write some new questions for each semester Used elsewhere –University of the Highlands and Islands –University of Aberdeen
Advantages of computer exams Speed of results & reduced time to mark Giving feedback easier Students happier (via interviewing students) Colleagues happy
POSSIBLE FUTURE USE OF OBSERVATIONAL ASSESSMENTS
Traditional assessment Participant presented with questions for direct response Observational assessment Observer presented with questions to rate participant according to pre-determined criteria Observational assessment vs. traditional quiz, test or exam
Monitor/observer logs inSelects assessmentSelects participant to be observedAnswers/submits responses to questions Results/feedback reported to stakeholders Typical workflow for observer
Observational assessments Benefits of doing on-screen vs paper –Saves time and money as no need to scan/transcribe –Results online instantly –Computer manages workflow –Participant gets feedback online –No illegible handwriting!
Can we computerize dental OSCEs? Existing paper- based OSCE form at Dundee Dental School
