Abstract

We identified midway through the year that a sizeable proportion of our second year students had difficulties with aspects of organic chemistry. It was essential to devise a solution that would require the students to be active in their learning - a set of ‘remedial lectures’ would simply not be sufficient. We felt that a set of tutorials would be a better approach, but we were concerned that, for some students at least, the learning would be restricted to the timeframe of the tutorial sessions. It should be noted that some of the less able students find textbooks difficult to interpret in this area, with reaction schemes often appearing cluttered with so much information being presented ‘in one go’. Hence we decided to support the delivery of the first tutorial with a suite of video resources. Students were instructed to complete the tutorial (PDF file on Blackboard) over Easter. A set of video tutorials on basic aspects of organic chemistry were made available, along with a set of animated reaction mechanisms. Usage of these resources was monitored with Blackboard’s statistics tracking features. Students were then instructed to submit their work after the Easter break, and copies were taken before the work was returned. The students then completed ‘Self-Assessment’ of their work, using a video of an academic talking through the mark scheme to guide them. The meechanism for delivery of student feedback was directly embedded into the core of the exercise, meaning we were able to obtain feedback from every single student who completed the task, and this made fascinating reading. Some comments include: “I found it very useful. its clearer to see where you’ve gone wrong if you’re marking it yourself rather than having a cross and a wrong answer you see why its wrong” “YES VERY!! please more during the year” “This has been a brilliant exercise if i am honest…” “… you can actually see where you went wrong and understand the areas to work on. It was really good that the videos paused to allow you to add up the marks and stuff.” “It was a brilliant exercise in covering things I had already understood, whilst simultaneously highlighting things I'd clearly managed to remember or even learn wrong…” “This is an excellent resource and should be developed further for organic chemistry” “…it is a very useful exercise, with the feedback accessible to watch again.” “Yes, it would have been even more useful before easter... “ “yes there should be more like this that are marked throughout the course” There were also some constructive negative comments including: “Useful but still does not replace contact time with lecturers in tutorial type situations”
