Schoology is a very powerful tool for delivering content digitally in the classroom.
Once you open a free account, you create courses and have students join them by typing in the access code which only you have. Once joined, the students are now members of this course and regardless of how many courses you create, students can access only those they have joined through the access code you give them.
What Can I Do With Schoology?
Set up digital quizzes easily and quickly. You have a variety of question formats including multiple choice, fill in the blank, matching, ordering / ranking, short answer, and long answer. Once students submit their answers, all are instantly graded (expect the short and long answer questions - these you manually grade).
From the "Results" tab of the quiz, you can view results by student and results by question to see what percent of your class was getting the correct answer for each question.
After quizzes are submitted by students, open your Gradebook for a breakdown of all grades by student and by quiz. This can be exported as an excel file if you need a paper copy.
After you make a quiz, you can export the questions to a Question Bank which makes tests like final exams much easier to put together. Just create a new quiz and import questions from the Question Bank, and change them as you will.
Create folders for each course you create and us them to store a multitude of resources for your classes to access. Schoology allows a wide variety of formats - Word documents, pdf's, videos, images, and much more.
The Home page for each course you create looks a bit like a facebook interface where you and your students can post questions, answers, or comments depending on the focus of the discussion you'd like to have. In the case of those students who are usually too shy to contribute to discussions, this really frees them up.
This is what I mostly use schoology for. It is extremely useful in getting a quick snapshot analysis of how your students are doing throughout a topic providing valuable information that guides future lesson plans.
