50 minutes. Self-marked against the rubric. 14 marks. In the full course this counts toward the labs and cases share (15% of the course grade). Write your answers in the boxes, then open the model answer and tick each mark you earned honestly. Nothing is sent or stored.
Scenario (invented)
A student (invented) is learning how a loan works. She has 12 practice problems, a 40-minute session and a short list of notes: principal, interest rate, repayment term, monthly payment. She wants to understand the ideas, not only memorise them.
Tasks
Task 1 (3 marks)
Write one what, one why and one how question about her notes, and say which two are elaborative.
Private: nothing you type here is sent or stored.
Task 2 (4 marks)
Plan her 12 problems as worked examples, completion problems and full problems, with at least 3 worked and at least 4 full. Show the counts add to 12.
Private: nothing you type here is sent or stored.
Task 3 (3 marks)
Give one concrete example of interest using invented numbers, and check the arithmetic: 5% a year on 200.
Private: nothing you type here is sent or stored.
Task 4 (4 marks)
Plan a 40-minute session with reading, self-explaining, writing questions and checking. Give minutes for each and the total.
Private: nothing you type here is sent or stored.
Rubric and model answer
Task 1: write elaborative questions (3 marks)
Model: What is the principal? Why does a longer term lower the monthly payment? How does interest add to the amount owed? The why and how questions are elaborative.
Task 2: plan the fading (4 marks)
Model: 3 worked, 4 completion, 5 full: 3 + 4 + 5 = 12. Other splits are fine if the counts sum to 12 and the minimums hold.
Task 3: give concrete examples (3 marks)
Model: 5% of 200 = 0.05 x 200 = 10, so after a year of simple interest the amount is 210. The numbers are invented.
Task 4: time the session (4 marks)
Model: reading 10, self-explaining 15, questions 10, checking 5; 10 + 15 + 10 + 5 = 40.
