I am finishing up Lesson 15 but this impacts 11 - 15. I found many students struggled with the amount of data they had to work with. We use Google Drive and by time they decided which data set to use, they were completely overwhelmed with how many data sets that had in their drive. I was also surprised how little they knew about spreadsheet programs so you really need to go over the basics. The code exercises do this but some students tend to just go through the exercises just to check them off as done, watching the steps and not reading the instructions. Next time I will allot more time to the basics and go through the code.org exercises as a class. Their PT practice is due tomorrow and I switched to Google Classroom for turning it in. Maybe it will keep them more organized. They also really struggled with pivot tables. Lessons 11 - 14 took me twice as long as I thought it would.
