The Interactive Radio Instruction (IRI) is one of the most effective aspects of direct teaching that has been used in education with great success levels. The IRI model for teaching involves having a predetermined twenty to thirty-minute direct teaching and learning exercises that are presented to students in a classroom every day. Lessons developed based on this model are tailored according to particular objectives for specific levels of disciplines such as science, maths, health, and languages in a national curriculum the intention being improving classroom teaching especially by having regular and structured instructions that help teachers in schools that lack qualified staff or adequate resources (Visser, Visser & Amirault, 2012; Di Gropello, 2006).
School broadcasting which in most cases is available in form of print materials, cassettes and CD-ROMS are avenues for enhancing how traditional classroom instructions are transmitted to students. This use of ICT does not replace the teacher but acts as a complementary resource to make the student better grasp the contents of a given curriculum. School broadcasting is more flexible compared to direct broadcasting since the teacher has the ultimate say over how to integrate available broadcast materials into classroom teaching and learning experiences.
