Behaviorism holds that the behavior desired by people is shaped by the actions and reactions of other people rather than by an individual's free will. This means that by carefully and deliberately modeling desirable behavior, morality and information are learned by the individual, so the important causes and motivations of behavior lie outside, rather than inside, an individual. Therefore for behaviorists, all learning is observable and measurable. Learning occurs in a behaviorist classroom as a result of responses to stimuli in the environment that are usually reinforced by the teacher, as well as feedback from actions on certain learning objects. The teacher helps the student learn by influencing him or her by explicitly identifying the desired behavior in measurable and observable ways. Programmed instruction, which applies the principle of flawless learning in the design of instructional materials and task analysis, is an application of the behaviorist approach. The mastery learning strategy is also based on the cognitive approach, with the cumulative nature of learning, where each student must master a certain unit before moving on to another unit. Finally, behavior modification and behavioral strategies, such as the rules-rewards-punishment approach, are one of the most widely used applications of behaviorism. When applied to online learning, behaviorism can work so that students can be informed of all learning. expectations that provide parameters within which to move. Whatever is expected of them can be told explicitly and specifically and these outcomes will be clearly delivered by the student in a given period of time. Course designers for online learning will be able to logically define sequences or… middle of the paper… be able to take responsibility and make decisions about their learning objectives. Instructors can focus on interactive, collaborative and cooperative learning activities. The instructor must develop skills in assessing students' current status and adapting the learning experience to support goal achievement. The instructor must also understand individual learning styles to provide effective strategies to help students plan, monitor, and evaluate their thinking as they learn. Because constructivism views each student as a unique individual, it is very effective in a one-on-one online learning course. The three different learning theories can be applied to online learning, although their degree of effectiveness varies. It is important to have a basic conceptual understanding of learning theories to be able to effectively develop a good online learning program.
