Word-problem features such as text complexity, charts and graphs, position of the unknown, calculation complexity, irrelevant information, and schemas impact word-problem performance. We compared the word-problem performance of typically achieving (TA) students and students with mathematics difficulty (MD). First, we measured the word-problem…

To become scientifically literate, students need to interpret science concepts using numbers, text, and visuals (Lemke 2004). Scientists use multiple modes to communicate their ideas to each other and the public, including images, text, mathematical notations, symbols, diagrams, charts, and graphs. Several of the science and engineering practices…

Some applications of mathematics to bicycle gearing, speedometers, and bicycle braking are discussed. A method of calculating bicycle speed is developed. (MP)

An actual application of linear graphs is described. (MM)

This article describes a social studies project for deaf students, which used the search for information concerning people with deafness to develop student skills in creating and interpreting various kinds of charts and graphs. (DB)

This book, describing the result of extended research on how charts/graphs convey information, develops a scheme for describing/analyzing information contained in graphs/charts. A psychological theory of knowledge of the reader and the mental events which occur in attempting to read a graphic display are the two focal points of the book. A…
