All good input. You should not be cluthching, changing gear or breaking in the turn, these should have all been done prior to entering turn. The reason your wheel skidded is because your engine speed did not match your road speed, either because you didnt give the throttle a blip prior to disengaging cluth, or you gave it to much throttle and lost traction. Either of these two scenarios is very dangerous, not only does it negatively effect traction, but also messes with the weight distribution of the bike and that can through you off. Basic rule for anyone that is not a very advanced rider is to have your breaking and shifting done prior to putting in any steering input, then you should be light on the accel through the corner, accel as you exit.
