Reproduce the core statement of Margaret P. Sinclair from memory before moving on to harder problems.

Reference excerpt

Margaret Patricia Sinclair (1950–2012) was a Canadian mathematics educator whose research publications included works on the use of dynamic geometry software in mathematics education[A] and the use of blended learning, a combination of traditional teaching and educational technology, in professional development for secondary-school teachers.[B]

Life and work Sinclair was born on 21 February 1950. After a year of undergraduate study in economics at the University of Toronto, Sinclair left school, married at age 18, and began working. From 1969 to 1974 she graduated from Toronto Teacher's College (now part of the Ontario Institute for Studies in Education), took correspondence courses through the University of Toronto, and taught at the elementary school level. By 1975 she left work to raise her children, two at the time and later three more. Continuing her education by correspondence through the University of Waterloo, Sinclair completed a bachelor's degree in 1988 and returned to work as a secondary school teacher, working within the Toronto Catholic District School Board and eventually becoming a school vice principal. She earned a master's degree in education in 1995, through York University, and a Ph.D. in 2001 from the Ontario Institute for Studies in Education. Beginning in 2001, she taught mathematics education at York University, initially as an associate professor of education and later as a full professor and co-director of the York/Seneca Institute for Math, Science & Technology Education. She died of cancer on 21 February 2012.

Recognition Sinclair was posthumously named a fellow of the Fields Institute, in 2012. The Margaret Sinclair Memorial Award Recognizing Innovation and Excellence in Mathematics Education, an annual Canadian mathematics education award administered by the Fields Institute, is named in her honor.

Worked examples

Example 1 — a first encounter with Margaret P. Sinclair

Start with the simplest possible case. Write down what Margaret P. Sinclair claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Margaret P. Sinclair before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Margaret P. Sinclair ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Margaret P. Sinclair

In research: Margaret P. Sinclair appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Margaret P. Sinclair in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Margaret P. Sinclair is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1950 births, 2012 deaths, Academic staff of York University, so understanding it makes those chapters shorter.
In everyday life: Look for Margaret P. Sinclair outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
