My last post sent me in search of a definition for academic rigor, and I found this handy little chart called a rigor and relevance framework. So, to my understanding, rigor means higher order thinking skills and real-life application of those skills. Good to know!
So my interpretation is that rigor is not, for example, memorizing certain verb tenses by the end of Spanish II, but rather to be able to apply the verbs to real-world, unpredictable situations. Sounds like academic rigor goes right along with communicative language teaching to me.
