The arrival of Web 2.0 has changed dramatically the way that we learn and we communicate. There is a growing number of educational courses that are massive, open, participatory and support the idea of distributed intelligence and lifelong learning. They are known as Massive Open Online Courses (MOOCs). That means that nowadays language competencies and intercultural skills are more than ever key qualifications for everyone who aims to work and live successfully in this new reality. These needs paved the way for the creation of the first "massive and open" online foreign language courses. With no doubt Web 2.0 services can support a promising and authentic Language Learning environment. However the design of successful MOOCs for Language Learning and their evaluation is not a simple process. This paper aims to provide guidelines for the design and evaluation of future Language Learning MOOCs to language teachers and instructional designers. More specifically, the paper will first present the challenges that a language instructor faces in order to design an online language course and then it will analyze the basic elements that successful online language courses should have. It will continue with a brief presentation of the shift from online language courses to "massive and open" online language courses. Next, it will propose a framework for the design and evaluation of an efficient Language Learning MOOC that basically supports the individual as well as the collective learning. At the end, the author will draw some first conclusions and will share the next steps of her on going research.
