Online learning, the way I see it, it is for advance learners of the English language only.  This is because there are lots of example to be used here that the learner might not have the chance to grab what is being conveyed.

Especially when it come to writing, the learner should have have atleast enough knowledge in the basic grammar terms and structures particularly subject and verb agreement.  As mentioned in the previous articles, it easy to learn how to write simple English essay if the learner should start from this very basic sentences like the simple sentence in the present form.

The first simple sentence then should be rewritten to its progressive and past tense.  This will a good start on how to manipulate writing and rewriting simple sentences. Of course, these sentences should be again rewritten on the next tenses which are the future, emphatic form and other.

Of course, the learner should familiarize first what are the symbles that signals each sentnces why it becomes present, progressive, past and future tenses. You may think this is easy but t is not for those who are not familiar with the language.  These are also some of the roblems that will be encounter in the learning English online even if the learing process is on one on one basis.
