I'd ask you their opinions on the results - can they help fill in the reasons for the 'unexpected' results (they will know much more about work ethic etc which won't be reflected in predicted grades)? Are there any general lessons to learn for this year? This will help when you do your results analysis. This is then a good intro to any specific things that *you* would like to happen in terms of teaching and learning - e.g. frequent, low-stakes testing; or half-termly assessments, or whatever it is. If you don't have specific ideas at the moment, then find out from them what will make their life easier/better - you can't promise anything but an open discussion based on their needs may help you prioritise your work over the next year. You could even sit down with the main headings of your department development plan and get their thoughts on the department's current position.
