Abstract: The emergence and use of MOOC provides learners with fine education and resources and a broad learning platform and space for their interaction. It has important implication for constructing effective learning environment by focusing on the social dimension of learning activities. This paper takes collaborative learning, a new dimension, into the current study and put forward suggestions and referential principles on how to construct effective collaborative learning environment based on the theory of connectivism, arguing that implementation of modular service in management system of learning can monitor and serve learning more effectively. Also, the communication module embedded realizes the connection of personal learning environment and reinvests it with a more efficient operating mechanism. Besides, providing the learners with reflective tools and services is an effective way to promote the metacognition triggered in learning regulation.
