I'm going to second Nexttime. It's crucial- and don't get me wrong it underpins a lot of other things you've put into your practice, but it needs to be grounded within reality and it really needs to be something that can be put into practice. A lot of people will learn it, they can recite it and they can probably cross-reference it with contradictory accounts, but when it comes to putting it into practice; for some of those selfsame folk that can quickly go out of the window.
Sure, we'd learn about Socratic Questioning; "Do you have an example"; "What would you recommend" etc etc. - Don't get me wrong, from a core concept point of view it's solid. But it's not really taught how to effectively question students. Typically the go-to for many teachers is to question a random member of the class ask them a question and wait until time has elapsed so they can figure out the answer and respond. Sure, it works. But it's archaic. It should be looking to innovation-
When I had an observation, one of the first things that my mentor evaluated was my use of questioning, since then I adopted a poll-esque method of questioning and assessing students. This is but one example. There are many more that you can find, but it matters provided it can be put into practice.
To summarize. Research does matter and it is absolutely crucial, but it is crucial only from the perspective of whether it can be used either directly in practice, or even as a reflective tool to something to aim towards when you're more experienced. It matters to the degree when it can inform and improve practice.
