ENL teachers with whole classes vs. pull-out groups
Do ENL (English as a new language) teachers generally teach a class of 20+ students, or generally do they pull out a small group of students and work with them?
I am a sub teacher in an urban school district and I have seen an ENL teacher teach an entire class of students whose English language ability is low. They had to teach history and biology classes and not even as a co-teacher. How could someone be expected to teach multiple subjects without being certified in a core area, and to students whose levels of English varies? I certainly did not see one-on-one or even small-group scaffolding. I am not even sure if the ENL teacher’s lesson plan was created by or even aligns with a classroom teacher’s lesson plan or pacing—although it just has to.
Most teachers are certified in and teach only one subject. Is teaching the whole class versus taking a small group out normal for ENL teachers? Or is this practice peculiar to my district?
I am asking because I am considering becoming an ENL. Thank you.
