A journey of risk Teaching concepts of risk within the Mathematics classroom Agenda How is risk defined in the “real world” and how it can be explained in the classroom. The teaching cycle of risk and how it fits within the New Zealand curriculum. Risk literacy and useful critical questions What concepts about risk do the students bring into the classroom. What tasks can be used to uncover your students’ misconceptions and help teach risk. Really useful resources. Where to from here. How risk is defined in the ‘real world’ Risk is an awareness that we have developed to help us understand and cope with the dangers and perceived uncertainties of life where the threat to an outcome is unknown. Everyday people make decisions that are based on statistical information – investments, insurance, product purchases, assessing tsunami risk, measuring the effects of changes to scheduling of transport services, political decisions and medical procedures. The definition of risk often depends in the industry or context in which it is being used. How risk is defined in the ‘real world’ One of the most common definitions of risk is as an uncertainty based on historical information. Risk can also be defined as – a hazard, a probability, a variability of a probability, the possibility of occurring a misfortune or loss, or as a threat that requires exposure and uncertainty. The fact that risk can have so many meanings often causes problems in communication How risk is defined in the ‘real world’ Risk analysis Expressed in mathematical terms a risky event is one associated with a probability of a loss of recourses like health, time, food or money (Martigon, 2014). All risk decisions have the basic elements of options, outcomes and uncertainties set in a social context and framed in a language that highlights some of the ways of looking at the question (Fischoff and Kadvany, 2011). How risk is defined in the ‘real world’ Risk analysis Risk analysis is the need to quantify risk and is usually written in numerical terms. This is what the Mathematics Curriculum has introduced at Level 2. Risk analysis brings reason and scientific deliberation to risk management. How risk is defined in the ‘real world’ Risk as a feeling The intuitive reaction to danger, often automatic, nonverbal and an experimental approach to viewing risk. Even though decisions are based on statistical information there is an emotional element
