In learning about the Social Interactive model of teaching, we were provided with the acronym/mnemonic device 'PIGS'. Each letter represents a characteristic of cooperative learning, which is the basis of the Social Interactive model. 'P' represents Positive Interdependence, 'I' is for Individual accountability, 'G' represents Group Processing, and 'S' is for Social Skills (Face-to-Face Interactions).
Effective mnemonic device can help learners remember important information; and they are not just for this particular model of teaching. I found the use of mnemonic device helpful in my Direct Instruction lesson plan that I presented during my fieldwork required for my General Methods of Instruction class. The lesson plan was on the topic of long division, and I helped my students remember that steps of long division with "Does McDonald's Sell Cheese Burgers", representing divide-multiply-subtract-check-bring down.
Here is a good guide to some mnemonic devices that are effective in the classroom.
