For the second year running, I had the privilege of taking three students to the VITTA annual conference to present a workshop on developing APPs using Corona SDK. This year, I took Ally from year 8, Yara from year 9 and Ping from year 11 (not their real names!). All three are members of the Avila College APP Group. Preparation In my reflection on last year's experience, I wrote that 5 weeks would be needed to prepare the students. Unfortunately, this year's conference was at the start of week 4 of the school term. Starting at the end of the last semester would have been impractical as it would have clashed with exams and report-writing. Still, we met twice a week and the girls ran one of the APP Group meetings as a rehearsal.
