How I Use It
I used Scratch with my 6th Grade Earth Science class by having them demonstrate mastery of both curriculum standards and basic coding. Students were to upload a background of the soil horizons and select a "sprite" of their choice. Students then used the different coding blocks to travel down to the different soil horizons, use text bubbles and animation with their "sprite" to teach others (or show content knowledge) of the soil horizons.
I believe that Scratch is a great tool to introduce coding to students in secondary classes, specifically middle school. I have used a variety of different coding tools, and this one seems a little more advanced to do the dashboard and amount of features that you can select. I would not recommend this for younger primary students, unless they are able to code well. I do like that there are many features that the students can explore and play around with as to not make the tool monotonous or boring.
