"At my school it has become time to formally institute a new curriculum structure that best suits the needs of our 21st century students. But which pedagogical approach do we go with? Or rather, should the question be, which acronym do we go with? There's IBL or EBL (Inquiry Based Learning or Enquiry Based Learning, depending on which brand of English you prefer), CBL (Challenge Based Learning), and an awful lot of PBLs (including Project Based, Product Based, Problem Based, Play Based, Passion Based and Process Based Learning!)."
