https://www.pianostreet.com/smf/index.php/topic,2449.msg21204.html#msg21204^this is an excellent way to gain technique in scale/arpeggio type passages - learn how to do it, don't skip steps.. you will be doing a lot of this if you intend to get good at piano. Apply this to your scale practice instead of just trying to play the whole thing up and down straight away.
This procedure will teach you how to use your playing apparatus efficiently without the need to consciously think in too much detail about how to move, instead you will just have a basic aim of how you want the notes to sound and how to be comfortable while playing just by "feel".
I don't want to spend a bunch of time practicing it that way only to figure out it's not optimal.
I might add that while direction does help, you can't just be told how to do it and practice it that way and end up with something optimal. Direction re movement helps point you in the right direction - but as a beginner you are essentially blinded as to what it should feel like to play with a good technique.
You have to discover how it works through appropriate practice methods.
You will learn sub-optimal playing habits because you don't know any better - you can't know any better because you're blind to them, and not attempting to play things that require an optimal technique.
You will have to fix them later you discover that you have a problem in the first place, this will happen bit by bit as the repertoire you attempt gets harder, and must be guided by the sound you are trying to create. You must be conscious of that all the time, in order to become aware that the technique you currently possess is not capable of producing the desired effect comfortably.
