If you are learning Spanish and/or want to improve your level of comprehension, check out the free Spanish MOOCs at MéxicoX by the Secretaría de Educación Publica. A few courses just started on Monday, September 21, with more starting in a week or two. There are many subjects available, ranging from science to education, as well as some courses concentrating on Mexico such as México multicultural; Literatura y cultura tradicional de México; México, sus grandes retos y oportunidades; and De México al mundo, los ingredientes (which looks delicious, btw.)
About half of these courses are also available through EdX, or you can create an account on MéxicoX’s platform which is powered by Open EdX. Most importantly, the courses I’ve checked out so far do have transcripts of the videos so you can read while you listen.
For those who have a higher level in French, the MOOCs offered by FUN are also a great way to improve or maintain your level as well as learn about new subjects from programming and public health to eco-tourism and history. There are even some courses offered in both French and English so you can compare the content if your level is too low to understand everything in French.
