Slide 3

About five years ago we scheduled class contact lecture time for activities such as: IT skills (spreadsheets, word processing) Use of software (e.g. Chemical structure drawing) and online resources Mathematics for Chemistry (for students without A-Level Maths) Since ~2009 these and other activities (events) have increasingly become provided for via screencasts with the contact time being released for more student-centred learning activities (e.g. workshops). To cite a specific example (2 nd year Inorganic Spectroscopy), Katherine Haxton has employed screencasts to change an 8-lecture course to 4 hours of lectures and 4 hours of workshop We (Katherine Haxton, David McGarvey, Laura Hancock) are now making extensive use of screencasting to fulfil a variety of purposes within the chemistry curriculum (and beyond).

Can free-up valuable lecture/contact time to use for more student-centred activities. They can generally be accessed from anywhere with an internet connection. They can be viewed again and again and again allowing students to study at their own pace and to digest complex and detailed topics. Some may be transferable across modules, years, programmes and cohorts. Others..... SCREENCASTS: PROS

Unhook the phone, hang a do not disturb sign and feed the cat Have a plan/script with clear sections. If available/applicable, employ navigational features for the end user and the facility to download the PowerPoint slideshow. Avoid reference to specific modules, dates, etc. which can impact on the shelf-life/versatility and may require time-consuming editing or having to re-record. Avoid editing unless absolutely necessary. SCREENCASTS: TIPS http://teachingchemistry.net/home/index.php/archives/267

Please keep the screencasts going they are very much appreciated by us students as they reinforce our resources and enhance our revision sessions. I think that the screencasts are an important part of my study as it helps me to understand topics better and at my own pace. Also, I think that more screencasts on topics such as thermodynamics and kinetics would be beneficial to my learning as it is hard to assimilate everything in lectures. Screencasts really help me The screencast pre-lectures and mp3 feedback was brilliant Excellent use of screencasts very beneficial to learning Screencasts are very helpful and work well in conjunction with lectures. Screencasts improve understanding before and after lectures TAKING THE LECTURE OUT OF THE LECTURE:

Slide 27

I am revising for exams at the moment, and the only way that I can understand some of the harder concepts is by having them explained to me via a screencast. I can watch them again and again until I understand the material, which is great. It is a much more efficient use of my time to watch screencasts whilst revising than reading through tricky textbook language. I think the screencasts are very useful. I've never experienced teaching in this way before, but when I came to Keele and I was introduced to them I was surprised at how good they are. You can go back to them whenever you want and use them to answer problem sheet questions, labwork and homework. I'm really glad I have access to them and it's like having a mini lesson at home one to one and you can pause and rewind if you dont get it the first time. I think as a student I am really lucky to have access to these screencasts and hope they continue throughout my time at Keele.

Slide 28

CONCLUSIONS Powerful and versatile technology with many applications. Very popular with students, who say screencasts benefit learning. We do need to learn more about how students use these resources and their effectiveness as learning resources. We plan to conduct interviews/focus groups during 2012- 13.
