Our Grade 3s are just finishing a unit about energy - it's part of Sharing the Planet. Last year the central idea of this unit was: energy exists in different forms and is changed, stored and used in different ways. The focus was on electricity and in the IT lessons students used a programme called Crocodile Technology where they dragged and dropped icons onto the screen to create circuits. I'm assuming this was an on-screen version of something I once did years ago with circuit boards where students could create actual circuits using wires and batteries to turn on light bulbs and as such I would define this as substitution.
Our Grade 1 and 3 teachers now all have their own class blogs. One of these teachers even has 2 class blogs (one for students to publish their writings, one for students to publish their performances). A couple of our teachers in Grade 3 have started quad blogging with other schools. Some are using the blogs as places where the students can do their homework. Parents and families are loving the interactive nature of the blogs. Students are learning how to be good digital citizens and what is and is not appropriate to publish. We have come a long way in a short time. These teachers are my shining stars.
I would like to acknowledge the work of Dr Ruben Puentedura who has been the force behind SAMR.
