We use C4E in our K-8 schools, and classic Canvas in our high school. A couple thoughts on this change:
1 - Parents with students at least one K-8 student have defaulted to the C4E view this year. For those parents who have a high school student (classic Canvas), they are losing the ease of access they now have to grades. When the UI displays C4E, parents can click the grades tab to view grades for just that child event if that child is older and is using the Classic Canvas interface. With the update, when the parent switches to an older child (high school in our instance), they see Classic Canvas and have the View Grades button on the right. Clicking this opens the grades page (...instructure.com/grades) that lists all courses for all students, which aren't even organized by student unless your institution has add a sort script to you custom JS.
2 - In Classic Canvas, parents see Recent Feedback on the right side of the screen, but not in the C4E view. I think they will find it confusing to have that information for one child and not for the other. I'm sure schools, and my office are going to field questions on this.
3 - The drop down menus are on 2 different sides of the screen. I found this confusing when testing and at first thought the menu had disappeared when I switched from a C4E student (menu, top-left) to a Classic Canvas student (menu, top-right). Can we get these drop-downs consistently located in the 2 views?
I'm glad that parents who only have the classic canvas view will be able to sort by children (per the May release), but there is an inconsistency in information presented in the 2 dashboards. I wish these changes were delayed until summer so we aren't causing confusion around viewing grades in the final months of school year.
