Looking through the many apps that are available I found many that can be very useful to teachers. They now have apps that can assist teachers by keeping all information about students and you have it in the palm of your hand. There are apps that can help make grading easier, that can keep a profile on each of your students, and can make it easy to email the administration or parents of the students about what is going on in class. Apps such as "Teacher's Assistant Pro: Track Students" lets you collect and save data about students' behavior or anything else you put in and makes it easy to email administrators or parents with all the details. This app also has many filters and a randomizer for student lists and groups for participation. There are a few apps out there that seem to be able to really help keep teachers organized and on top of their students.
Technology is an amazing thing and it has come a long way. I am amazed at the potential that these apps have to make the lives of teachers easier. I think that some of these apps can be so very useful if teachers are willing to learn to use them.
