There are two similar words: Synchronous and Synchronized. Both are derived from the Greek Chronos and relate to time.
Synchronized is used for activities where time must match exactly. We synchronize our watches, synchronized swimming requires that swimmers exactly match each other's movements.
One dictionary definition: to cause to go on, move, operate, work, etc., at the same rate and exactly together
Synchronous has a similar implication but usually refers to a single event.
Definition occurring at the same time; coinciding in time; contemporaneous; simultaneous.
There is a specialised usage in IT: when two computers are interacting they may do synchronously or asynchronously. Synchronously implies that one computer will send a message and wait for a response from the second computer before doing further work. In asynchronous processing the first computer will send a request and expect an answer some time in the future, meanwhile it will continue with other tasks.
As @1006a has said, education terminology makes similar use of synchronous and asynchronous; depending upon whether the teacher and student interact directly.
You are speaking about dispositions and attitudes, which are not time-related. Hence I advise you not to use the terms synchronous or synchronised. I think the concept you are trying to express is that education is facilitated when the teacher's disposition and the student's disposition are aligned. We do not require that teacher and student have the same disposition, but that the dispositions are in some way complementary. As a trivial example: the teacher wants to teach, and the student wants to learn. More deeply: the teacher has a disposition for dialogue and the student a disposition to use such dialogue constructively.
My recommendation: use term such complementary and conflicting or harmonious and discordant.
