There are pros and cons to the online environment, and one of the negatives is the loss of "immediacy." When a student has a question, he can raise his hand in class; however, in the online environment, he must wait until the teach logs on or read his or her email (unles it is a synchronous class). The teacher, can however, devote time through the email to fully answer the question, while uploading web content for deeper understanding of the issues. This technique of transcending the traditional to online environment, is a blend that enhances student learning and outcomes. (SLO's) When transferring the traditional content to the web, there is a plethora of educational net resources that can enhance the lecture. Most books today have an online component for the students, even if the course is a traditional (on-campus) one. A true online course, uses an e-text, and all online resources for tests, assignments, posts, and other media-enhanced work. Therefore, there is the traditional class, the blended (or hybrid) class, the online class, and self-learning course, as well.
