School science is dominated by textbook-oriented approaches to teaching
and learning. Some surveys reveal that students have to read, depending
on academic level, between ten and thirty-six pages per week from their
textbook. One therefore has to ask, To what degree do textbooks
introduce students to the literary practices of their domain? Few
studies have addressed the quality of science curriculum materials,
particularly textbooks, from a critical perspective. In this light, we
are concerned in this book with better understanding the reading and
interpretation practices related to visual materials - here referred to
as inscriptions - that accompany texts. Our overarching questions
included: 'What practices are required for reading inscriptions?' and
'Do textbooks allow students to develop levels of graphicacy required to
critically read scientific texts?' Some of the more specific questions
included: 'What are the practices of relating inscriptions, captions,
and main text?, ' and 'What practices are required to read inscriptions
in school textbooks?' That is, we are interested not only in
understanding what it takes to interpret, read, and understand visual
materials (i.e., inscriptions), but also in understanding what it takes
to engage inscriptions in a critical way. It is only when citizens can
critically engage with language (texts, speech) and inscriptions that
they become knowledgeable users of television, newspapers, and
magazines, who can choose or leave aside particular expressions as part
of the particular politics that they participate in.
