Reading is often described as being either intensive or extensive. Intensive reading is reading practice done with a shorter text. Much attention is usually paid to practicing the mechanics of reading (explicitly practicing particular reading styles such as skimming, scanning, reading for detail...) and to actual structures of text (grammatical features, discoursal features, features connected with genre). An intensive reading text is likely also used to introduce new vocabulary items. Practical Readings by Anthony Bruton and Angeles Broca is an example of a text that takes an intensive reading reading approach. In extensive reading, on the other hand, the emphasis is on reading large amounts of text and on developing reader confidence, reading fluency and reading speed. Extensive reading is often connected with the idea of graded reading, of using simplified texts. Come Fly With Us by David Capel is an example of extensive reading, as are the Helbing Readers that Abax carries in Japan. The two practices are of course not exclusive. Students can—and many would argue should—be doing both intensive and extensive reading.
An interesting case is that of the prize-winning Fiction in Action: Whodunit, designed as a bridge into extensive reading and which one of the authors, Marcos Benevides, describes as being intensively extensive.
