The ability to read scientific and technological materials is a growing need. Tech Talk contains authentic materials and excerpts from nonfiction books and from NPR that deal with popular, newsworthy issues in science and technology. Along with readings, the book also contains related exercises in comprehension, vocabulary, discussion, grammar, and writing. Although the readings in the book were selected to appeal to all readers, they may be especially helpful to English learners who are engineers, scientists, or university students in technical fields. In addition to providing reading practice, this textbook aims to: teach grammar through examples of real usage; provide practice in the writing styles commonly used in science and engineering: explanation, persuasion, and critical analysis; provide opportunities for verbal practice through class discussion; and, encourage English learners to read independently and to learn language through reading.
