This study aims at assessing instructional radio broadcast case instruction of civics andrnethical education in the primary schools of Addis Ababa. To meet this objective, anrninvestigation was made on input, process and output. In doing so, the researcher tried tornidentify the conditions necessary for the successful implementation of instructional radiornbroadcasts. Moreover, he has tried to find out problems that hinder effectivernimplementation.rnThis study adopts survey research methodology that contains both qualitative andrnquantitative data collection instruments. Through questionnaire, classroom observation,rnand content analysis sufficient data were collected from 600 students, 12 teachers, andrnone expert. Throughout the selection of samples, random sampling technique wasrnpersistently employed except in the last stage of selecting sample students wherernclustering (i.e, male and female) was used. Consequently, three sub cities were sampledrnof which 6 woredas and six primary schools were sampled (i.e, 2 weredas from each subrncities and 1 school from each wereda).rnThe finding suggest that implementation of instructional radio broadcast indicated thatrnthe majority of teachers and students have positive attitude towards the broadcast. Onrncontrast the program content and presentation is not acceptable by the teachers andrnstudents.rnWith this regard, the basic hindrance for effective implementation of instructional radiornbroadcasts in particular to civics and ethical education originates from inadequaternsupply of input materials, poor functioning, unsuitability of instructional curricularnlessons with the existing curriculum, inability to take into account the diversify learners,rnlack to give emphasis on positive ethical values of the learners etc. suggest thernprevalence of constraints on successful implementation of instructional radio broad castsrnat sample schools.rnSo, stakeholders need to give special emphasis to these constraints and above all improverneffectiveness of the implementation of the entire instructional radio program.
