I’d go from there to wo + de = my, ni + de = yours. Zhe shi wo de shu. Zhe shi wo de shu ma? Shi. Zhe shi wo de bi ma? Shi (nod). Zhe shi ni de bi ma? Bu (shake head). Zhe shi wo de bi ma. Shi (nod) etc.
Then, wo (hand on chest) ni (point at camera) wo (hand on chest) shi (buddha pose) ninde (explain that de makes “you” “yours”) laoshi (say teacher). wo shi ni de laoshi (do “all” the gestures).
ni shi “wode” laoshi ma? (quizzical expression) Bu (shake head) ni (point) bu (shake) shi (buddha) wo (hand on chest) de laoshi. Wo shi “ninde” laoshi.
Ni (point at acamera) shi wo de xueshang ma?
Xiang xiang (point at head - “think” expression).
“xuesheng” shenme (say what) yisi (say meaning) “xuesheng”.
Wo shi ni de laoshi. Ni bu shi wo de laoshi. Ni shi wo de xuesheng ma? Xiang Xiang… Dui! ni shi wo de xuesheng (say you are my student). Wo shi nide xuesheng ma? Bu. Etc.
She should use this kind of method to teach real people and find out how many repititions it takes for people to actually begin answering questions. The same number of repititions should be done on the video.
She should “emphasize” the tones vocally, and she should move her body (first - raised eyebrows, second - move her torso up and right, third - dip up and down from the knees, fourth some sort of abrupt downward motion) while doing the other gestures to indicate meaning. She should encourage her students to move along with her.
Every class should beging with dajia hao. Jintian women yao xue…
Essentially what she should be doing is asking herself what she says over and over again in English. Whatever it is she should teach and then say over and over again in Chinese. It is amazing how many quite professional programs don’t make that leap. For example, they tell you to go to page 13 whatever but never teach “fan dao di shi san ye.”
I would “not” teach beginners characters for at least a year. Then again I don’t “know” characters either so…
