Word Clouds as a Learning Analytic Tool for the Cooperative e-Learning Platform NeuroK.

Word cloud or tag cloud is very popular these days. It is a tool used to display text data summarization in a visual way very easy to understand. However, it has not been extensively used in teaching, especially in elearning, where it would make a differential advantage. This research presents the definition and implementation of a word cloud tool in a social network-based e-learning platform (NeuroK), which is based on the principles of neurodidactics. The different features developed and the results are shown. Several options to compare word clouds from students and teachers allow the teacher to follow the development of the course, and they provide him more information to facilitate the evaluation process.
