If the course has been designed to be user (student) centered, rather than teacher centered, your role primarily will be to guide learners in creating meaning from course materials. They may do this by working alone on some assignments, but more often by sharing ideas and discovering connections among ideas through collaborative learning. Group activities, such as discussions and simulations, allow learners to collaborate within the course structure. However, individual and group activities should take place within an online course. Both asynchronous and synchronous communication and activities are important in an online class. You will use both types of communication to build a learning community. As well, a group of learners with different preferences and styles should find a variety of individual and team activities and assignments. In this way, each learner should have at least one type of activity that matches his or her preferred learning style or method of communication. Asynchronous communication and activities take place outside of real time. For example, a learner sends you an e-mail message. You later read and respond to the message. There is a time lag between the time the learner sent the message and you replied, even if the lag time is short. Bulletin board messages can be added at any time and read at your and the learners’ leisure; you do not read someone else’s message as it is being created, and you can take as much time as you need to respond to the post. Asynchronous activities take place whenever learners have the time to complete them. For example, viewing videos linked to the course site, reading a textbook, and writing a paper are all asynchronous activities. In contrast, synchronous, or real-time, communication takes place like a conversation. If your class uses only writing-based tools to communicate, the only synchronous communication possible is a chat session. Everyone gets online in the same chat room and types questions, comments, and responses in real time. Synchronous activities may include chat sessions, whiteboard drawings, and other group interactive work. If your class involves multimedia tools, synchronous communication might involve audio or video feeds to the computer. Some “online” courses require learners and teachers to get together at least once (or sometimes several times) in person, by conference call, or through closed-circuit television links. Although these examples of synchronous communication take place offline, they may still be important communication tools for distance learners who spend the rest of their time working online. Occasionally, group synchronous activities take place on site, too. For example, lab sessions or proctored testing sessions may require learners to complete activities with other class members in real time. Learning communities may use chat rooms for discussion, interviews, Q & A sessions, and team work sessions. Community members often prefer realtime communication instead of asynchronous communication for work sessions, although both synchronous and asynchronous communication are used frequently. Location, personal/work schedules, and time zones determine which forum is best for a particular situation or community. Group members also keep in touch through notices and responses tracked on bulletin boards or posted to a community’s Web site, mailing lists, and bulk and individual e-mail.

Sometimes, especially in colleges or universities new to online education,- teachers have the responsibility of turning on-site courses into their online- counterparts. This process may be the institution’s (and teacher’s) first- foray into online education. Teachers may determine that a new course- would be well suited to the online format and would be an important- addition to the curriculum. The administration agrees, and the mechanism- for offering such a course (or courses) is put into place. H...
2. Creating a Positive Learning Environment within Different Times and Spaces
Online classes vary in the number of learners and the time frame for the course. Some programs continue year round. For example, in the design and structure for one online course, learners may work on their own and turn in assignments to a teacher who evaluates the materials. There are no required chat sessions or other forms of synchronous communication. The learners in this type of program like the freedom of completing assignments at their own pace, as long as they finish within the parameter of the course’s...
3. The Five Principles for Developing an Online Curriculum in Online Education
Perhaps the following list can provide suggestions for implementing successful online programs within an academic institution, while lessening the fears (or the downright animosity) among faculty and administrators. The following five suggestions may pave the way for better relationships among all faculty and administrators and help those who plan future online curricula: 1. Recognize that the ways courses or programs may be created can differ, but the resulting “product” should be equally high qu...
4. When and How to Gather New Materials for The Online Course
As you develop new materials, you first need to evaluate what you have and what else you need. Some materials are probably still useful: 1) They are not outdated; the information is still accurate and the tone still timely. 2) They have been tested and still provide learners with activities for skill development or thought-provoking ideas for discussion. 3) They allow learners to interact with them independently as well as within a group, and they permit myriad responses. 4) They are cost effective and available for ...
A balance between constructivist and behaviorist objectives and methods probably needs to be determined for your institution’s programs. Educators certainly must be actively involved in determining the appropriate pedagogical approaches for their market of students and the types of courses that they teach. Providing an effective learning environment to more students worldwide certainly is an altruistic objective, one that can promote educational ideals—that in itself is at least a theoretical benefit t...
6. Tasks for Online Teachers
Although online teaching can and should be as high-quality and effective- as on-site education/training, some professionals are better suited than- others to working online. Online educators need to facilitate individuals’- learning; bring together students with diverse interests, skills, and needs- to form learning communities; clearly state expectations and maintain high- standards; be adaptable in regards to learners’ needs; communicate clearly- and effectively; and enjoy working with the Internet...
7. Honesty and Ethics in the Classroom
For any learning community to succeed, members must trust each other and the teacher, and all community/class members must act ethically at all times. Students should be encouraged to collaborate on group projects or even research for individual projects, but assignments made to individuals must be independently completed. Everyone must understand that original work is of paramount importance and that any use of outside sources must be clearly and thoroughly documented. A thorny problem in all educational prog...
8. The Teacher`s Role as Facilitator in Online Education
Facilitating the formation of learning communities is important in the first week of class. Through your group messages, first bulletin board postings, and first weeks’ office hours, you make learners feel that they are part of the larger group studying the same materials at the same time. Introductions among all class members are important, as is socializing the group to the “rules of the road” for taking this class. Then you can work to facilitate smaller communities, made up of personalities you t...
9. Privacy and Security ~ How to create a safe learning environment
Creating a safe learning environment, in which teachers are fairly certain that students are who they say they are, only authorized learners and academic community members have access to online information, and electronic information is protected, requires the technical specialists, faculty members, and administrators to have a plan in place. Most often, the technical security of a system is the domain of IT specialists, who receive input from other members of the institution. Other policies, such as those involvi...
10. When to Update Course Materials
As you teach a course, you should keep track of learners’ problems with certain assignments or tools. If you spend a lot of time each term explaining instructions or interpreting a source, those materials should be updated. When you have taught a course several times, it becomes apparent quickly if some materials are difficult to understand or tools frequently work improperly. A few learners may not understand an assignment or may have trouble getting something to work at the course site. When several students ...
