I would like to see a more "primary or elementary" looking interface for elementary students. Since the pandemic, many elementary teachers and parents have been frustrated with the look of a more "higher education" interface.
Elementary students need a much more simplistic look and feel. I love Schoology and all it has to offer. I can tell you from first-hand experience, the immediate "first impression" can make or break a student's online experience. I had many parents that immediately were frustrated because the interface is much more "higher education" looking and then those parents would not pursue the online learning with their child any further.
