    16. 16. Using Pencasts to teach Problem solving in Thermodynamics <ul><ul><li>Tutor Pencast – explaining an idea </li></ul></ul>
    17. 17. Main Findings <ul><li>Start up issues </li></ul><ul><li>Building capacity - Tutors making pencasts </li></ul><ul><li>Students use of pencasts </li></ul><ul><li>Students making pencasts </li></ul>
    18. 18. Start up issues <ul><ul><li>Purchasing pens and books took time </li></ul></ul><ul><ul><li>Loading the software onto staff computers took time </li></ul></ul><ul><ul><li>How easy the software was to use </li></ul></ul>Issues that needed some work at the beginning:
    19. 19. Building capacity – tutors making pencasts <ul><li>“ I am more relaxed with the time constraints as courses have been merged I can give the students the pen (pre teach) and carry on with other students and return to the pen and student and they often have the concept.” </li></ul>Comment by tutor:
    20. 20. Building capacity – tutors making pencasts <ul><li>“ It is another tool that I can use. It freezes time, allows me to be in two places at once.” </li></ul>Comment by tutor:
    21. 21. Students use of pencasts <ul><ul><li>“ This was really useful especially for some of the hard problems” – Thermo </li></ul></ul><ul><ul><li>“ It helps us with new ideas” – Thermo </li></ul></ul><ul><ul><li>The Tutor “is on tap and I can go back half way through a problem” - Thermo </li></ul></ul>Some comments by students
    22. 22. Students using pencasts <ul><li>“ Once the students realise that we have a replay they seem to relax during the maths and pick up the concept faster. It is as if well if I miss something I can replay it. They don’t seem to want to listen and use the pen too often – the pen transferred the knowledge as some kind of insurance scheme.” </li></ul>Comment by tutor:
    23. 23. Conclusion Did the tutors gain anything? Did Students gain anything?
