An approach of computer-assisted learning in veterinary education at the University of Cambridge, involving the development of four types of learning module, is outlined. A tutorial on regional perineural anaesthesia in the horse, based on the familiar tape-slide format but with significant improvements, is described. A question and answer self-assessment package and a computer-based 'digital lecture' are also discussed, together with a case simulation involving the investigation of a polydipsic dog. All the tutorials were developed using standard software packages and image digitising processes. The philosophy behind the development of these computer-assisted learning packages is discussed.
OBJECTIVE: To determine the effect of computer-based medical teaching (CBMT) as a supplementary method to teach clinical problem-solving during the clerkship in neurology. DESIGN: Randomized controlled blinded study. SETTING: Academic Medical Centre, Amsterdam, the Netherlands. METHOD: 103 Students were assigned at random to a group with access to CBMT and a control group. CBMT consisted of 20 computer-simulated patients with neurological diseases, and was permanently available during five weeks to students in the CBMT group. The ability to recognize and solve neurological problems was assessed with two free-response tests, scored by two blinded observers. RESULTS: The CBMT students scored significantly better on the test related to the CBMT cases (mean score 7.5 on a zero to 10 point scale; control group 6.2; p < 0.001). There was no significant difference on the control test not related to the problems practised with CBMT. CONCLUSION: CBMT can be an effective method for teaching clinical problem-solving, when used as a supplementary teaching facility during a clinical clerkship. The increased ability to solve problems learned by CBMT had no demonstrable effect on the performance with other neurological problems.
The aim of this 45 min, 60 megabyte, modular program is to initiate students, scientists and engineers of biotechnology, biomedicine and agrofood industries into isoelectric focusing (IEF) and titration curves for analytical (e.g. IEF, zone electrophoresis, isotachophoresis, electrotransfer) and preparative (e.g. ion-exchange chromatography, chromatofocusing) application of charge-dependent methods. For advanced teaching, the following theoretical and practical aspects may be of interest: pH gradient engineering, IEF resolving power, generation of pH gradient, sample-ampholyte interactions, pH gradient drift, immobilized pH gradients (IPG), IPG-two-dimensional (2-D) electrophoresis, preparative methods with multi-compartments and IPG membranes, capillary IEF, isozyme analysis, etc.). The program associates fixed and animated drawings, and computer-assisted simulations, with spoken and written commentaries (in English). It is illustrated with numerous IEF gel patterns and titration curves and some video sequences to be run on a multimedia PC with MS Windows 3.1 (or later releases) as the only software. The linear presentation of the program may be used directly on the PC, or may be projected on a screen from the PC, for small classes or for a larger audience (200 persons). Its development as an interactive multimedia program is in progress and will soon be available on the Internet.
