The Language of Functions and Graphs: An Examination Module for Secondary Schools

Malcolm Swan

Shell Centre & Joint Matriculation Board | 1982 | 240 páginas | PDF | 17,321 Mb

The Language of Functions and Graphs is now regarded as a classic book on the teaching and assessment of graph interpretation skills.
It focuses on developing fluency in using various mathematical representations to describe and analyse the real world, and on the teaching tactics needed to handle pupil discussion in groups and with the whole class. Unit A of the classroom materials tackles the interpretation and sketching of scatter graphs and line graphs - an area where most pupils need help if they are to go beyond the plotting and reading of points to the global meaning of the graph; this material is accessible to a wide range of abilities. Unit B develops modeling skills - the search for patterns in a realistic situation and their expression in verbal, graphical and algebraic forms: this unit is more challenging. Each Unit takes about two weeks of mathematics time in the 13-16 age range. In addition there is a collection of further problems, as well as the assessment tasks with marking schemes for GCSE.
"By addressing the query of 'how do you assess open ended problem solving', the Shell team generated a classic resource, from which has grown the substantial literature of alternative assessment of today." - AAMT
"The materials are very well produced with attractive worksheets and an abundance of materials from which to select." - Mathematical Gazett
