Seems like everybody is getting into learning online, and E-Learning articles are becoming more and more popular. Keep in mind that E-learning articles must be written for teachers or instructors, and be on the topic of teaching. These may be articles that talk about ways that teachers can instruct more efficiently online, or ways to increase online attendance of their students, just to name a few.
Some Common E-Learning Mistakes
Articles aimed toward students, about learning online or taking online courses, belong under their course topic. For example, an article about an online course to learn bookkeeping belongs in the Accounting category. While your article may actually be a form of E-learning, publishers in this category are looking for content aimed at instructors.
