Models, maps, global pictures and realia and specimen are all examples of aids used in the teaching process. These play a vital role in helping the teacher achieve set goals for each particular lesson. Teaching aids are an integral component in any classroom. The many benefits of teaching aids include helping learners improve reading comprehension skills, illustrating or reinforcing a skill or concept, differentiating instruction and relieving anxiety or boredom by presenting information in a new and exciting way. Teaching aids also engage students’ other senses since there are no limits in what aids can be utilised when supplementing a lesson. Teaching aids have proved to be a formidable supplement for teachers when the reinforcement of a skill or concept is necessary. Not only do they allow students more time to practice, but they also present the information in a way which offers students a different way to engage with the material. In this regard, therefore, the aforementioned aids are applied by teachers who want their lessons to be effective, motivating and attention-grabbing. This scholarly piece of writing hence will strive to enumerate and explain the merits of models, maps, global pictures and realia and specimen in the teaching process. To begin with, a model is a representation of an idea, object, event, process or system. Models contribute significantly to the success of any lesson. They play a crucial role in the teaching process. One justification for their inclusion in the teaching process is that they contribute to an authentic education delivery system, where teaching reflects the true nature of the subjects taught as much as possible. Benedict (1995) augments that Models provide an environment for interactive student engagement. It is not a hidden fact that significant learning gains are achieved when students participate in interactive engagement activities. Hence, it is imperative that the learning environment created around a model must provide an interactive engagement experience. Additionally, models in the teaching process are useful for helping students learn quantitative skills such as graphing, graphical analysis, and visualization; statistics; computational skills, mathematics to mention a few. Using models, students are able to have hands on and positively participate in the learning process. Another very important aspect of using models in the teaching process is that they allow students or learners to perform sensitivity studies to assess how changes in key system variables alter the system's dynamic behaviour. Adewoyin, J. A. (1998) adds that such sensitivity studies can help learners identify leverage points of a system to either help one affect a desire change with a minimum effort or to help estimate the risks or benefits associated with proposed or accidental changes in a system. To further the discussion, in biology, models play a very significant role in the teaching process. Firstly, in a laboratory setting, the model organism's immediate response to the change of environment enhances students’ learning and serves to hold their attention and interest. Bolker, J. A. (1995) explains that students not only understand what they see, but also believe it is real. The use of model organisms involves hands-on activities that provide a unique experience that could not be obtained with other teaching methods. This no doubt goes without argument that models in teaching leave behind an indelible mark on the learning process of the learners. Moreover, by working with model organisms, students are able to explore scientific methods and concepts themselves and consequently come to understand about the investigative nature of the scientific enterprise, including how conclusions are drawn from data. Conclusively, model organisms are well-established experimental systems possessing certain properties, and are more amenable to classroom use. Models provide accurate and useful representations of...
