As it will take considerable time and considerable technical effort to correct all the materials concerned, David has put a 'sticking plaster' on (the 'Important Note') for now - immediately above the video concerned saying:
My apologies for any inconvenience this may cause course participants.**Important Note**
At 50 mins 28 secs (slide 57 on assessment), I refer to the first bullet point, “From sound to print for decoding”. This should be, “From print to sound for decoding”. I continue with the second bullet point, “From print to sound for encoding”. This should be, “From sound to print for encoding”. This error is on the video and the printable slide, and in the audio commentary. (Thank you to Alison for drawing this error to my attention.) Debbie Hepplewhite
