This paper describes the roles of teachers and administrators in  online learning, and discusses the rules of best practices for both.
 
Ziad D. BAGHDADI writes, "There is  no universally accepted definition of what a best practice is. However, the  United Nations Educational, Scientific, and Cultural Organization (UNESCO)  describes best practices as having four common characteristics: they are  innovative; they make a difference; they have a sustainable effect; and they  have the potential to be replicated and to serve as a model for generating  initiatives elsewhere (UNESCO, n.d). When applied to a particular condition, a  best practice must ensure the delivery of the most effective outcome, based on  repeatable procedures or activities that have been proven they over time for  large numbers of people. 
 
The best  practice in education is the most efficient (least amount of effort) and  effective (best results) way by which society transmits its accumulated  knowledge and skills from one generation to another. The use of computers and  the Internet in transmitting knowledge and skills is blossoming, and new  technology is increasingly being used to complement established education  practices and develop new ways of learning such as online education. For  technology to offer powerful learning tools for engaging students, online  curricula must be developed based on best practices principles and taught by  highly qualified teachers using principles of effective online teaching. An  academic curriculum is composed of several coherent courses related by themes,  enabling the learners to move from the basic foundation of knowledge to more  advanced, sophisticated levels of critical thinking and mastery of skills. The  attention devoted to each and every course composing the curriculum will lead to  a powerful teaching tool, ending with a recognizable scientific  degree.  
 
Similarly,  the traditional role of teachers is being challenged as a reflection of changing  teaching philosophies. Online learning, with its steady increase in popularity  and acceptance, exerts more strain on teachers to change their tools and  concepts of teaching and evaluating. As an  online teacher, close adherence to instructor best practices and expectations  ensures a successful outcome of the learning process, which is rewarding to both  the teacher and learner alike."
