McKenna Williams noticed an increasing number of students not completing their independent seatwork in language and spelling.She expects students to take responsibility for working independently while she works with small reading groups.Now she wonders whether she should start allowing students to work together in pairs or trios rather than continuing to require them to work quietly on an individual basis.Her common sense tells her that she should continue to require quiet individual work.Her colleague Cal Sitton disagrees.He allows his students to work in pairs.Explain why McKenna should not rely on her common sense as she solves this teaching problem.
