It's interesting to see your perspective on the BICS and CALP reading. I also had a similar experience where my conversational Chinese fluency is better than my academic Chinese fluency until I was able to learn academic fluency in School. I've also noticed that many students learning a new foreign language in schools often have better academic language fluency compared to conversational. It really depends on the amount of usage and the critical time frame to learn languages as shown in the video and the Lippi Green reading. I also believe that there is a distinction between language in a conversation setting and a language setting. However, I agree with Nelson Flores that the BICS and CALP framework diminishes the value of BICS and home language practices. It also doesn't encapsulate the fluid nature that emergent bilinguals use language. Although the BICS and CALP framework did work, it may be time for a better framework which could be Flores' Language Architecture which doesn't separate academic and conversational language, but rather sees both as building upon each other and used in different contexts.
