David Dewhurst, of the University of Edinburgh gave an evaulation of online medical programmes offered by his institute. He described how online scenarios could allow students to conduct 'experiments' that they couldn't otherwise do, working on tailored 'virtual patients'. This certainly has the advantage of avoiding costly and time consuming ethics procedures. Not ALL practical skills can be learnt online though - a fish dissection I did in my second year springs to mind. But online resources can certainly be useful in supporting limited wet lab sessions. In this case, watching a video uploaded onto the University online network was invaluable - when practicals are typically hectic, cramped, rushed affairs with the demonstrators struggling to turn everybody out after three hours, any advance preparation helps the experiment to go more smoothly, allowing students to learn more from the experience. perhaps a good example of online/ practical complementation is the 'Hazard Perception' element of the driving test. Exposing learner drivers to these situations ie real world would be frankly dangerous, yet it cannot replace the practical 'hours behind the wheel' ( more like days in my case) needed to master the skill.
Dewhurst cited studies which found that online lectures or practical simulations were at least as good as (if not better) in terms of data interpretation, communication and knowledge acquisition. Nevertheless, most students preferred the actual lectures (to get hints of what may come up in the end of year exam, perhaps?). Students also seemed to access online resources at different times of e day/night, supporting the view that greater flexibility complements student lifestyles. On the other hand, the success of online platforms very much depends on the dedication and expertise of the institution. In some cases, whole modules can be put together out of lectures or resources cannibalised from other courses. Hence, the student pays for a course that lacks coherence and is not tailored to their aims. It takes time to master the skills required to develop online resources, placing researchers and teachers under additional pressure - it is much easier to put together a series of lecture slides. The more creative the course developer, the more interactive the module will be, containing more quizzes and self-assessment tests to aid knowledge retention. Dewhurst made the interesting point that, despite these time constraints, teachers/researchers often reject imposed third party designs, seeing them as unfit for their needs. Success is also dependent on the student's ability to manage their own learning progression - making the transition between spoon- fed GCSEs and independent study at University even more important. Should Sixth Form schools thus be introducing more independent and online elements in A Level provision? Most of the students subscribing to the Online modules offered by e University of Edinburgh are apparently professionals in full time work, roughly 30 years of age, that pay their own fees, with an approximate 50:50 male/female ratio. Many are internationals, who benefit by not having to travel or obtain a visa. It seems that a desire to remain in full time work is a key attractant of online courses, especially for those just advancing their careers.
For myself, I believe that online resources can be very beneficial in supporting practical lessons, especially where time and cost can be factors that limit the learning experience. But they can NEVER replace actually DOING the skill. I learnt a fair bit about hygiene and bacteria when I took an online course in food preparation so that I could volunteer with a student cookery group. But I only gained confidence in the kitchen by cracking eggs, making a mess, burning myself and getting over my fear of turning the oven on. What do you think? Comments below please!
