Most teachers just don't care!
I came to teaching as a second career. Teaching got me out of the condo and the additional money buffeted all my cash burn. Having said all that I almost went to teacher's college after university. There were a lot of difficulties along the way but to be honest most of the pressure I placed on myself.
In my opinion 80% of teachers don't care and never will. Paying them more than 35K per month is just money in the bin. 10% care somewhat and 10% take it on as a career and profession. Here, I'm discussing EFL and all schools sans true internationals. I'm amazed at the full grown shirkers and artless dodgers. Having done this for a decade I shouldn't be but as we start the new year, I am.
Professional development is not easy to come by but few have any interest. It's all about silly games, methods to waste time, nailing down a staple of activities and tired worksheets so as to place a water bottle and your school owned notebook on your desk and slip off somewhere for an hour or three or...simply head home. Year on year they learn nothing new then gripe about their pay. They've become accustomed to the school and when they weigh a pay package at 42k compared to the 37k they've been making as long as they can remember, they decide that the effort is just not worth it. So, there they sit.
Another thing I have noticed that teachers never do is help students on their own time. It seems that any moment that could be spent off campus is better so than time spent helping their students. It's so self serving. New teachers bring in a bit of freshness and positivity but I'm struck by the false pride. Even when I started at 50 + I knew I hadn't a clue how to teach and was constantly searching for mentors and ideas. So few and far between I had to train myself. It's even a bit shocking as I see many of these younger teachers having gone through these limited programs playing games and doing board races but all that stuff academically speaking it's just purely a waste of time.
Moreover, with few exceptions I'm absolutely stunned at the lack of depth that most teachers have related to technology.
It's not been an easy road. One needs to constantly be searching for a school that's a fit for you personally. It will never be perfect and nothing even close. In the end, I traded my perfect school for money and although I am making approximately 20k + per month more at this new school plus bonus + perks, it is a bit of a lunatic asylum.
Why in world would anyone be teaching students with such abysmal English abilities? Not only are these poor kids challenging in themselves but the classes are complete headaches and the schools are generally disasters. This is precisely where a person with any sort of talent and career ambition does not want to work. There are better schools with far better facilities, students with exceedingly better English abilities, his students with grand ambitions and motivation. If you are sincere and genuine about your career then seek to educate yourself to a point where you can provide the best students something of value. Then, go make yourself 80,000 baht a month.
