Are we as objective as we should be about the new teaching techniques we try? The argument that we aren’t, usually put to us by researchers, goes something like this: We read, hear about, or otherwise discover a new technique. It could be a strategy or a different approach. Maybe it addresses a problem; it might develop a skill. Whatever the criteria, the new technique strikes us as a good idea. It seems doable—something we can pull off and something likely to work with our students. More directly: we like the new techniques that we decide to try.
