To be accurate, that's not 'playing jazz' per se, that's merely plugging in a scale over a handful (three actually) of chords\bass notes. It might get someone started in being interested in learning how to improvise, but I'd approach it differently.
How would you introduce a novice to the art? This seems a reasonable place to start.
Since I've made my living as a jazz keyboard player (organ and piano), I can pass on how I started. My first experience with music was watching TV and paying along. Regardless of the style of music that one wants to become familiar with, the first step is to mimic it in real time ... play along with it whether it be the TV, radio, or other musicians. You learn a style and improve your ears at the same time. (Analysis on paper comes later, your ears and fingers come first.)
Plugging in a scale and playing over a chord is just plugging in a scale and playing over a chord.
I'll pass on a true story regarding this method. I played piano in a big band for 20 years. The bari sax player was not a jazzer and at one time studied with another jazz pianist to 'learn' how to improvise.
There was a jam session that I attended and this bari player sat in and played like there was no tomorrow. He sounded great, he really did. What he learned was to plug in scales over a chord, different scales for different chords.
Where I (and everyone else) could see where this method was flawed, the next time during a rehearsal where he had a solo, he sucked big time. He couldn't transfer that 'learned' information to a new setting. He would have been forced to go back to that teacher for each and every song and have help figuring out the scales for every solo. (He wasn't taught the big picture per se, he had to have every picture drawn for him.)
He wasn't taught how to think, he was taught how to be a student and I suppose that's great if you're the teacher and making your living from students. My two cents.
