See above. There is no universal convention.

How What do English native speakers call their teachers or lecturers in the class?

I assume you're asking how we address them. It depends on the school, the age of the students, the formality demanded by the faculty and probably other factors.

At my first and middle schools (age 4-12), all teachers were "Miss/Mrs/Mr + surname".
At my secondary school (age 12-16), the same was true with the exception of one teacher who insisted on "Sir" and another who insisted on our using his first name only.
At my sixth form college (age 16-18), almost all the tutors/teachers expected "Miss/Mrs/Mr + surname". My music teacher was happy to be called "Adrian" and one of our English Lit teachers made us call him "Prof" for the first term, then told us it was just a joke he played on all his students and from then on we were to call him by his first name (which I've now forgotten).

One of my friends went to a very strict Catholic school from the age of 8 to the age of 16, and was taught by nuns. She had to address them as "Sister + name" (some didn't make sense - there was a "Sister Kevin"!)
The son of someone I know goes to a Montessori school and all the teachers go by their first name only.

At university, it was mostly first names for me.

Thank you. Yes, I meant the way they address their teachers in university and school.

In my country, Iran, my students at university usually call me 'master' and even 'professor' and young learners usually call me 'teacher + surname'. They usually address lecturers and teachers this way.

How do you want to be addressed? Don't you tell them how?

[tulipflower]

No, I haven't told them. I always wondered what they should call me in an English class. In Iran they never use first name to address a teacher or a lecturer. In schools, they usually say 'teacher' and I though it's not a proper way to call their English teacher. Now I found that Ms, Mrs and Mr are the most common ways to call teachers. I also doubt about 'master' that the university students use to address their lectures.

It's also worth knowing that, in general (both in and out of school), Americans are more prone to use first names than the British are. For example, my stepdaughter's first name is Caitie, and her seventh grade students call her Miss Caitie.

(That's unusual, but it's a good illustration of Ems' remark that there are no rules about what we call teachers and professors.)

Simply tell them how you want them to address you. It's as simple as that.
