Talkbank - - 12 24 UNK %xRES:In this problem, students are asked to divide 200 dollars in the ratio 1 to 3. Problems involving calculations and algebraic manipulations such as this, were considered to have "using procedures" problem statements. These accounted, on average, for 61% of the problems in each Australian lesson (Video report, figure 5.8).During the interval 10:21-13:34 the teacher and students use procedures to complete the problem; specifically, they divide the 200 dollars by four and then assign the appropriate amount to each part of the ratio. In the Australian data set, on average, 64% of the problems presented as "using procedures" in each lesson were then implemented as "using procedures" (Video Report, figure 5.10).
Talkbank - - 12 25 UNK %xTEA:The students could see boxes of chocolate candy on my desk. Some were keen to get to the part where they opened them!
Talkbank - - 12 26 T you have to use your imagination here.
Talkbank - - 12 27 T smarties later.
Talkbank - - 12 28 T money now.
Talkbank - - 12 29 SN money.
Talkbank - - 12 30 T I want you to divide two hundred dollars in the ratio one to three.
Talkbank - - 12 31 T so create for me the ratio one to three again.
Talkbank - - 12 32 T right.
Talkbank - - 12 33 T so you have?
Talkbank - - 12 34 T one box on the left, three boxes on the right.
Talkbank - - 12 35 T now the whole idea (.) Dylan.
Talkbank - - 12 36 T the whole idea about dividing things up in a ratio is that you have equal piles in each of your four (.) equal amounts in each of your four boxes.
Talkbank - - 12 37 T so what will go in one box if you have to fill four boxes equally.
Talkbank - - 12 38 T Ashley?
Talkbank - - 12 39 SN fifty dollars.
Talkbank - - 12 40 T fifty dollars.
Talkbank - - 12 41 T so four shares is equal to two hundred and so one empty box or share has fifty, so the ratio one to three will equal fifty to one hundred and fifty.
Talkbank - - 12 42 T yes?
Talkbank - - 12 43 T okay.
