Encounter with Educator and Delta Certification Advice

Should we use L1 in the English classroom? Is there a problem with discrimination against non-native English teachers? Is taking the Cambridge DELTA a good idea? Why is Zdenek's cat so weird ... and it's not even his cat? As an ESL teacher, I'm sure you've asked yourself these questions before. (OK, maybe not the cat one.) In this chat with English teacher Zdenek, we discuss all these things and more. An interview with an ESL teacher, by an ESL teacher for ESL teachers. Enjoy!
