This study investigated the effect of instructional materials on the teaching and learning of social studies in junior secondary schools in Yenogoa local government area of Bayelsa state. The research was guided with four purposes, four research questions and hypothesis. Survey design was adopted and both students and teachers constituted the population for study. A sample of hundred subjects was drawn from five schools and was administered questionnaires. Data collected was analyzed using simple percentage (%) for research question and chi square for hypothesis. However, the four hypothesis were tested at 0.05 level of significance and were all rejected. The study revealed that selection of relevant instructional materials, availability and ability of the teacher to improve all had significant relationship with the teaching and learning of social studies in Yenogoa local government area.
Learning and teaching is the concern of trained teachers. Though learning is a complex process, it can however, be defined as a change in disposition, a relatively permanent change in behavior overtime and this is brought about by experience. Learning can occur as a result of newly acquired skill, knowledge, perception, facts, principles, new information at hand etc. (Adeyanju, 1997) Learning can be reinforced with instructional materials of different variety because they stimulate, motivate and as well as arrest learners’ attention for a while during the instruction process. Instructional materials are learning aids and devices through which teaching and learning are done in schools. According to Akamobi, (1998) instructional materials are those materials used in classroom or workshops for instruction or demonstration purpose by students and teachers. Chauha (1973) saw them as actual equipment used as “hands on” process by learners in order to develop the degree of skills sought by the course of requirement. Examples of instructional materials include visual aids, audio aids, audio-visual aids, real object and many others. The visual aids in form of wall charts illustrated pictures, pictorial materials, textbooks etc. thus audio instructional materials refer to those that make use of the sense of hearing only like the radio, audio tape recorder etc. an audio visual instructional material therefore is a combination of devices which appeals to the sense of both hearing and seeing such as television, motion pictures and computers. From the above definitions of instructional materials, we may gather that social studies as an area of education deals with instructional problems and solutions through the use of various visual, audio and audio-visual materials and equipment.
