Description

A 36-item assessment developed by Lowrie and colleagues to measure Grades 4–6 students' decoding of six graphical languages in mathematics, including number lines, graphs, maps, and diagrams.

Components

  • The GLIM test: a 36-item instrument for assessing decoding of six graphical languages: The Graphical Languages in Mathematics (GLIM) test is a "36-item test" developed to determine students' decoding performance for each of the six graphical languages (Mackinlay, 1999). Items were selected from a bank of 58 items trialled with primary-aged children, drawn from state, national and international year-level mathematics and science tests, with high-literacy-demand items removed. In its final form it comprised six items from each language category, organised into Easy, Moderate and Difficult subtests of 12 items each, scored 0 or 1 per item with a maximum of 12 per difficulty category.
