Teaching/learning aids

  Teaching aids: is all tools, instruments, materials, equipment, and devices that used in and out side classrooms to improve the teaching and learning process  for example, Books, Motion and still pictures. It is very important to develop higher order thinking and problem solving and improve student motivation, attitude, and interest in learning. It is useful to enable students to visualise or experience something that is impractical to see or do in real life. Teaching aid should be directly supports the curriculum objectives and provides opportunities for student collaboration. Cone of Experience utility in selecting instructional resources and activities is as practical today as when Dale created it. The cone is based on the relationships of various instructional experiences to reality (real life).The bottom level of the cone, "direct purposeful experiences," represents reality or the closest things to real, everyday life. Each level of the cone above its base moves a learner a step further away from real- life experiences.

In my opinion it is useful lecture because it give us the importance of using teaching aid in teaching and must be support the curriculum.
