* Step 1: Build setup, record video, digitize video Step 2: Research question, Coding scheme (What are we going to score?) Step 3: Make videos, score observations. Step 4: Filter and analyze data, make video clips of highlights. * WITH VIDEO CLIP ‘Kids 15 sec.mpg’ RUNNING IN LOOP Score behaviors, i.e. record sequences of events and the time at which they occur. Using mouse to select codes from codes window is somewhat unwieldy because you have to look away from your focal subject. Can customize this slide per customer, with video clip similar to their research. * Score behaviors, without a coding scheme: simply type your notes in the Comment column. Using mouse to select codes from codes window is somewhat unwieldy because you have to look away from your focal subject. Can customize this slide per customer, with video clip similar to their research. * * SWITCH TO THE OBSERVER!
