No, it's not the same. Perhaps you shouldn't be teaching at all as your basic reading comprehension is severely lacking!

Doing 8 hours a week, or whatever amount of hours is not lazy so long as you're still ensuring that your students are getting the very best by way of lesson preparation. Thought and planning in to what an how your students are going to learn and a wide range of skills used throughout the lesson. This is not lazy. This is having part-time hours but still being dedicated to your students and your job as a teacher.

Saying you do the bare minimum by way of lesson preparation in order to maximize your free time is lazy. Nothing to do with how may classroom hours you teach, it's to do with your attitude towards that lesson.

These two are different things. I've never said less hours = lazy. I've said doing the bare minimum for your classes is lazy. Do try and keep up.

Tourist-teachers are people who teach purely to fund an extended holiday and not because they care about teaching. Being a tourist-teacher does not automatically make you lazy, just not as dedicated as somebody who teaches because they are actual educators. Most tourist-teachers will not put as much thought or planning in to a class. They do not have the same training or qualifications as a real teacher and as such theit lessons will not be as beneficial. If you can't answer your students' questions because you don't know the grammar without looking it up on google, you are not as helpful to your students as someone who can. If your idea of teaching is conversation only, then you are nor as beneficial to your students as somebody who can guide them through all aspects of ESL learning.
