I am loving Seesaw more and more! I have students post videos on Seesaw using a program called Myon ( a program with a collection of books that can be read aloud by the computer and then reread by the students). The students take a screen shot of a passage from their book, read the passage, and find the feature of the week with “green screening”. This week they are looking for contractions. As I watched the videos I found that they mix contractions with possessives (something I didn’t even think about). I knew the misconception of comma vs. apostrophe and teach examples and non-examples. Teaching non-examples are just as important as examples. So seeing the students explain their work helped me to see this misconception. Now I will start teaching the misconception of possessives vs. contractions. I can figure out how students think when I see them post videos. Their videos drive my instruction.
