  1. TAKING THE LECTURE OUT OF THE LECTURE • David McGarvey • Chemistry • School of Physical & Geographical Sciences • d.j.mcgarvey@keele.ac.uk

  2. PRE-LECTURE SCREENCASTS THE EYRING EQUATION

  3. ‘HOW TO’ SCREENCASTS EXCEL SOLVER

  4. ‘HOW TO’ SCREENCASTS WEB OF SCIENCE

  5. ‘HOW TO’ SCREENCASTS BASF SUNSCREEN SIMULATOR

  6. Whole Lectures Lecture supplement Use of software A screencast is a recording of the computer screen that can include narration and synchronous visible author activity such as mouse movements, annotations, editing and operational tasks. Model Answers Feedback (individual or cohort) Use of online resources Worked examples Open Day Talks

  7. SCREENCASTS: WHY? • Prime students for classes using pre-lectures. • Release contact time for more interactive learning activities. • As independent study tools for particularly challenging material. • Effective means of showing ‘how to’. • As revision tools. • Useful for colleagues http://teachingchemistry.net/home/index.php/archives/267

  8. LECTURE REPLACEMENT SCREENCASTS MATHEMATICS FOR chemistry BEDMAS Significant figures Principles of Logarithms Units and unit conversions Properties of Logarithms Fractions Powers, reciprocals and roots Units and Equations Graphs and Tables Rearranging equations Equation of a Straight Line Scientific Notation Integration (3 Screencasts) Differentiation (3 Screencasts) Linear equations and making curves straight

  9. EXAMPLE PRE-LECTURE SCREENCASTS 1st year chemistry Writing Lewis Structures Equations of Light Using the Arrhenius Equation Formal Charges in Lewis Structures IR Spectroscopy 1st order kinetics VSEPR NMR Spectroscopy Integrated Rate Laws MO Diagrams for HeteronuclearDiatomics Effective Nuclear Charge MO Diagrams for HomonuclearDiatomics Some of these topics have also been supplemented by additional screencasts on worked answers to problems etc.

  10. EXAMPLES OF ‘HOW TO’ SCREENCASTS Plotting a Straight Line in Excel WEB OF SCIENCE Plotting Spectra in Excel CHEMICAL STRUCTURE DRAWING LINEST BASF SUNSCREEN SIMULATOR MS EQUATION EDITOR EXCEL SOLVER

  11. SCREENCASTING Software Camtasia Studio - powerful editing tool - create table of contents and navigation bar http://www.techsmith.com/camtasia-gslp.html

  12. 1st year chemistry (70 students, 91% response rate) COURSE EVALUATION DECEMBER 2012 • Have you accessed the screencasts for any of the following? (please tick all that apply)

  13. SCREENCAST: EFFECTIVE NUCLEAR CHARGE (~70 chemistry students) Class test 3/12 Exam 9/01 Lecture 20/11

  14. STUDENTS’ COMMENTS ON SCREENCASTS: ‘I like the fact that I can prepare for the lectures to turn up understanding what the lecturer is saying. Also I found it really easy to use new software and Excel where I had the screencast to help me’. ‘The pre-lecture screencasts helped me to understand the lecture content’ ‘Allows you to go to lectures knowing something about the topic, makes it easier to learn’ ‘Makes you think about what the lecture is going to be on – also a good revision tool’ ‘Excellent use of screencasts – very beneficial to learning’ ‘Screencasts improve understanding before and after lectures’ ‘If you don’t understand it, you could go back and watch the screencast over and over’. ‘They were so detailed’.

  15. STUDENTS’ COMMENTS ON SCREENCASTS: ‘They took you through what to do step by step as if you were in a lecture’. ‘They were good revision’. ‘Very thorough and lead on to lectures well’. Very useful for pre-lecture info and teaching extra-curricular skills (equation editor in Word etc.)’. ‘They were useful for explaining things after the lecture’ ‘Extremely helpful, always there when you need to go back to them’. ‘They are idiot-proof to find on the VLE and idiot-proof to understand’. ‘They actually helped, especially when struggling after lectures’. ‘Visual tutorials – shows exactly how to use a program’.

  16. STUDENTS’ COMMENTS ON SCREENCASTS: ‘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 don’t 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’.

  17. SCREENCASTS: TIPS • 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. http://teachingchemistry.net/home/index.php/archives/267

  18. SCREENCASTS: PROS • Can free-up valuable lecture/contact time to use for more student-centred higher level activities. • They allow the teacher to go into as much detail as desired without worrying about how much time it takes. • 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. • They can be transferable across modules, years, programmes and cohorts. • They are well used by students and very popular. • Useful for demonstrations of teaching technology on open/visit days. • You can teach your colleagues!

  19. SCREENCASTS: CONS • Time-consuming to plan and prepare • Shelf-life • Managing student expectations
