Real-Life Contexts

1. Maths disciplinary tasks 2. IT-based assessment system 3. Attitudes toward learning maths

Wong (APEAC, 12/9/13)

• Singapore Maths Curriculum (2013): stronger emphasis on “solve real-world problems”; “connect mathematics that they have learnt to the real world” • Help students gain knowledge about the world, while honing their maths skills • Aligned with international trends

Overview

OECD: Mathematical Literacy • An individual’s capacity • to identify and understand the role that mathematics plays in the world, • to make well-founded judgements and • to use and engage with mathematics in ways that • meet the needs of that individual’s life as a constructive, concerned and reflective citizen

A particular item costs $6. Shop X advertises, “buy four items for the price of three”. (a) How much does a customer have to pay for 4 such items in shop X? (0.98/1) (b) What is the percentage discount for the customer who buys 4 such items from shop X? (1.61/2) (c) Another shop Y offers, “buy three at the regular price and pay 50% for the fourth item.” Shop Z offers a voucher of 10% on the total amount paid. Your parents wish to buy 4 such items. Out of these 3 shops (X, Y, and Z), which shop gives the best deal? (3.52/5) (d) Other than the amount you have to pay, what other reasons would you give to your parents to support your choice?

Decibel Question: Results

The loudness of sound is measured in decibels (dB). Noise from heavy traffic is about 85 dB and this can cause hearing damage if one is exposed to it for 8 hours or more. For every 3 dB over 85 dB, the exposure time before damage occurs is decreased by half. (a) If the noise is 88 dB, what is the exposure time before damage occurs? (b) John likes to listen to his music using ear-plugs at high volume of 100 dB. How long could he do this before damage occurs?

Students’ Responses to Feedback

• Teachers can enter own feedback comments • Comments can be saved and shared within school

Overview

• Every question is tagged to several feedback comments • Correct answer: Gives general praise and reiterates the correct procedure • Wrong or incomplete answer: Hints on how to proceed further

Teacher Can Add Feedback

Wong (APEAC, 12/9/13)

Overview

Customisable Feedback

• Closed questions: Automatic marking o Expedite marking; alleviate teacher marking workload o Consistency in marking • Open questions, workings: Semi-automatic marking o Teacher selects score from given scheme o Recommend teachers mark by questions to note different student solutions o Expedite marking; alleviate teacher marking workload o Consistency in marking Wong (APEAC, 12/9/13)

Customisable feedback

• After marking and entering feedback: Students asked to reflect on teacher feedback • 3 choices of student responses; encourage metacognition and reflection • Teachers to follow up

Questions Appreciate the connections of mathematics with real life situations. It is easy to add my own feedback to the system. By focussing on open-ended questions, I know more about my students’ thinking, e.g., different methods used. I prefer this system to manual marking.
