TEACHING DEVICES
Dear student welcome to Unit 5. This unit is about Teaching Devices.
Indicators:
Activity 1:
(ii) Give two(2) examples of each of the types mentioned
5.1 Teaching Aids and Types
Teaching aids are objects or devices used by a teacher to enhance classroom instruction and promote active participation of learners during teaching and learning activities to achieve learning outcomes.
Objects such as textbooks, pictures, maps and other display materials are teaching aids. Also devices like computers, smart phone DVD, films are used in the classroom as teaching aids.
Four main Types of Teaching Aids
(i) Visual Aids: Helps the learner to acquire knowledge through his or her visual senses. They are aids that are looked at (appeal to eye sight). Examples include charts, silent motion pictures, projected displays, filmstrips, models, graphs, diagrams, chalk boards, marker boards, magnetic boards, flannel boards, etc.
(ii) Audio Aids: They help the learner to acquire knowledge through his auditory senses. They are aids that are listened to (appeal to the ear and hearing). Examples include tape recorded lesson, radio, teaching machine, broadcast talks, etc.
(iii) Audio-Visual Aids: These are aids that are both looked at and listened to in order to see and hear at the same time. They are sensory aids that help to make teaching effective, interesting and concrete. Audio visual aids provide the learner an opportunity to utilize both his or her auditory and visual senses to gain the desired knowledge and learning experience. Examples include videos, sound motion films, television, living objects like a bird, etc.
(iv) Activity Aids: They are a combination of all the teaching aids that are necessary to enable the learner to engage in a specified useful activity. Examples include:

5.2 Importance of Teaching Aids.
Activity 3:
5.3 Principles for the selection of Teaching Aids
The aid should be relevant to the topic being taught.

5.4 Guidelines for the Effective Use of Teaching Aids
Activity 5:
5.5 Computer Simulation
Computer simulation is the process of mathematical modelling, performed on a computer, which is designed to predict the behavior of or the outcome of a real – world of physical systems. In this case the physical system in being simulated.
Simulation of a system is the running of the system model. Consequently, one should build a model first before running that model as simulation. Computer simulation is useful because it enables one to explore and gain insight into new technology and to estimate the performance of systems.
Computer simulation serves as a “Substitute Laboratory”. For example, in the various branches of science, they can be used to provide teaching and training experiences that would not be practicable using conventional methods on grounds of cost, time, safety etc.
Examples include the use of computer simulation to provide learners insight into systems such as nuclear reactors and experiments in genetics.
Activity 6:
(ii) State and explain the main types of improvisation
(iii) Give two (2) examples each of the types of improvisation.
5.6 Improvisation
It is the use of low cost/no cost readily available materials in the locality to make equipment/objects/apparatus and use these for teaching and learning in the absence of the original equipment/objects/apparatus.
Improvised materials are a replica of the original equipment and apparatus made with low cost or no cost readily available materials in the local environments.
5.6.1 Improvised material are of three types
This means using improvised materials in place of real or original materials.
For example, using a lighted candle as a bunsen burner; using lime juice as acid.
That is when some changes are done to the locally available material before it can be used to represent the original one.
For example, cutting a plastic bottle into two and using the bottom half as a beaker and top half as a funnel.
That is when the locally available materials are used to make a model of the original object in teaching.
Activity 7:
5.6.2 Teaching Aids that can be improvised
a . Charts and Wall Charts
Charts refer to displays on a large piece of manila card or cloth that are designed to be shown to a class or a group in the course of a lesson.
Wall charts are similar to charts except that they are pinned to a wall of the classroom or on a bulletin board and are meant for casual study of the context of a formal lesson.
Even though charts and wall charts are available commercially, it is still often necessary to make one’s own in a specific way.
Models can be applied in several ways in the teaching and learning process.
