The third edition of Changes replaces over 50 percent of the readings with yet more compelling pieces of writing that students and teachers are sure to find interesting. The 45 unadapted readings provide student writers at the advanced level with a variety of genres of writing, models of good writing, stimuli for discussion and inspiration to write their own texts. The authors have improved on the successful 2nd edition by weaving into each unit “toolboxes” that teach essential reading and writing strategies. The authors have also provided more examples of “academic discourse” and have increased the emphasis on citing sources, a key skill for college writers. The book still has three thematic units. However, the readings are now grouped into thematic subsections. Each reading is accompanied by a full set of pre-and post-reading and pre- and post-writing activities, all of which encourage student collaboration.
