There are a few exceptions, and where applicable, that difference will be noted on the course description page under "Additional Resources Required."
If a course requires a textbook, you are responsible to own that textbook prior to the start of the course.
In most cases, we are not going to cite "chapter and verse" from the textbook in conducting class, but I am borrowing enough of the author's approach that copyright says that it is the right thing to do to buy the author's book.
Unless we specify an edition of that textbook, any edition will do. It will be helpful to look up some of the background information that we will not cover in detail in assignment instructions, but our goal is that you can conduct most of the course aside from the text.
Upon enrollment, you will receive a code to allow you access to the Google Classroom for the course in which you are enrolled. You will also be provided with a link to that course. Please make sure that you keep these in a convenient place, as trying to get you into a course that you have lost the code for is going to be time consuming for both of us.
You will receive, execute, discuss, and turn-in your assignments through Google Classroom. To get to Google Classroom, you simply go to your Google Account, look at the Apps that are in the "grid" button at the top right of the screen. It should show up as one of the apps to which you have access. This is how you will conduct the course.
For some of the courses, there will be other technology that the students will need to get access to. In many cases, this will involve signing up for a free account. There are a couple of cases where the accounts are not free. This fee will be additional to your enrollment, and it will be described in the "Additional Resources Required" section of the Course Description page for the course in question. You will need to make sure that you are able to access this technology during the course because it will be required in order to accomplish the assignments that we have given you. I have tried to find free alternatives wherever possible, but there are a few exceptions where open source software has not quite caught up with "commercial grade."
Please pay attention to these requirements, as you will not be given a refund because you did not pay for the technology requirements for a course. Access to this technology is the responsibility of the student.
