Regardless of which embedded skill or area of engagement you are teaching, providing students with the ability to check their grades online is a good idea. Students appreciate being able to check how they are doing in a course.
Nevertheless, entering grades directly into the gradebook in Scholar is frustrating. I recommend that you add assignments that are offline activities instead of adding columns directly in the gradebook. I created a 7-minute video that shows you how to use the offline activities and how to use categories in the gradebook to weight grades. The video is located here: http://www.screencast-o-matic.com/watch/cXQery0i9.
Another option is to enter your grades in Excel and then upload the file to Scholar. If you want to do this, be sure to download the empty gradebook from Scholar first so that you have the correct format for Scholar. There is a 5.5 minute youtube video that demonstrates the whole process. It’s at http://youtu.be/uq83pFtEkDM.
