Teaching Learning Materials (TLMs) and Aids, which form the focus of this issue of Learning Curve, an indispensable part of a teacher’s bag of tricks, is a generic term that describes any material that supports and buttresses teachers’ efforts in getting a class of diverse capabilities to understand the basics of any learning. They have to fulfil some basic requirements: simplify concepts, provide the chance of practice, increase interest and motivation, help to explain complexities, concretise abstractions, enrich the course — though, of course, a single TLM may not meet all the above criteria. Thus, they are various kinds of TLMs, starting with the humble, but ever-present, blackboard (which has come in for much adverse criticism) and going all the way up to ‘smart classrooms’, with all the advanced technology they entail. TLMs have the added value of aiding the memory — when children see how a concept/rule of language/experiment works, it is more likely to stay in the active memory than just learning the same thing by heart. This issue presents a wide variety of opinions and experiences with TLMs and Aids.
