\"V53N4<\/a>OAME Gazette Volume 53 Number 4<\/strong> released and\u00a0includes three new articles and ten regular columns.<\/p>\n

In their co-authored work, Revealing Subjective Probability in the Middle and High School Mathematics Classroom, Egan Chernoff and Jack Chernoff contrast subjective probability with classical and frequentist probability foci. Using a deck of standard playing cards, they further share an innovative approach to the teaching and learning of a central tenet of subjective probability, for recommended use in the middle or high school mathematics classroom.<\/p>\n

In his article entitled The Mathematics of Photographs, Tim Sibbald builds upon his previous work (Mathematics of a Hill, 2014) and makes the case that sometimes modelling a physical object, seen in terms of the photographic image, can be useful for identifying patterns. Through the use of a number of intriguing geometric diagrams and photographs with grid\/intercept overlays, Sibbald models his stated goal of providing a workable sense of how the taking of a photograph transforms the geometry of a physical object.<\/p>\n

Roger Herz-Fischler, in his article entitled Doing Maths Algorithmically in the Age of the Computer, introduces and advocates for the use of a comprehensive, open-source software known as Octave. He also makes the case for introducing high school students to an algorithmic approach to solving certain complex problems; and points out the perceived dichotomy existing in the Ontario Mathematics and Computer Science curricula. Through the analysis of a familiar \u201cbirthday problem,\u201d Herz-Fischler describes the utility of the software Octave, and further offers a link to a free introductory resource.<\/p>\n

Regular columns include the following highlights: OAME President, Paul Alves (President\u2019s Message) reflects fondly on his term as President; Assessment Abby (eponymous) answers a submitted question regarding the evaluation of curriculum expectations; Mary Bourassa (Technology Corner) highlights a new website entitled, Which One Doesn\u2019t Belong, and created by Christopher Danielson; Mirela Ciobanu (In the Middle) looks at Singapore\u2019s model-drawing approach for solving word problems using text, pictorial, and symbolic representations; Greg Clarke, Agnes Grafton, Ross Isenegger, and Markus Wolski (Provincial Digital Learning Resources) present and extol their two new web\/mobile learning tool apps, Money and Notepad; Lynda Colgan (Hey, It\u2019s Elementary) tackles large numbers such as billions, trillions, quadrillions, and\u2026googolplexes [see also Richard Schwartz\u2019s fantastic new book\/website on a similar theme, Really Big Numbers (AMS, 2014)]; Stewart Craven (Fields Institute MathEd Forum Report) provides speaker highlights from the Saturday March 27th meeting; Shawn Godin (What\u2019s the Problem?) poses a problem regarding telling time with two given hourglasses; Ann Kajander (MB4T) discusses student explorations of pattern rules using virtual algebra tiles; Todd Romiens (OAME\/NCTM Report) discusses the teaching of mathematics to preschoolers; and, as usual, this issue also features the rich contribution of ideas for elementary math teaching as found in the Abacus insert, co-edited by Mary Lou Kestell and Kathy Kubota-Zarivnij, and focusing here on Spatial Reasoning via Patterning and Algebra and Data Management and Probability strand problems.<\/p>\n

Volume 53 Issue 4 also includes several special features: (i) a review by Tim Sibbald of Barnett\u2019s inspiring documentary tale, The Spark: A Mother\u2019s Story of Nurturing Genius, in which she recounts her autistic son\u2019s incredible and ongoing journey through life and learning; (ii) several further entries of Ontario mathematics education researchers and their respective projects; and, (iii) selected excerpts of Canadian researcher contributions to Lerman\u2019s new Encyclopedia of Mathematics Education (2014).<\/p>\n","protected":false},"excerpt":{"rendered":"
