The study attempted to evaluate the effectiveness of educational radio programsrnin three primary schools in Addis Ababa. Fifteen p eople (three principals, sixrnteachers and six students) were selected as a source of information. Theirrnselection was based on willingness to participate in the s tudy (for the teachers)rnand academic perfonnance, age and sex (for students). A qualitative case studyrnwas employed. The dara was collected through interviews, observation C/I/cirndocument analysis. The study revealed that primary schools' principals an.drnteachers have good perception towards the educational radio programs.rnFurthermore, students are more interested to acquire knowledge from educationalrnmedia, such as educational radio. Due to this most of the teachers try their bestrnto utilize the programs regularly. However, the utilization process affected byrn. different factors. Some of the major identified factors were teachers' lack ofrntraining on radio instruction utilization, inavailability of support materials such asrnradio teachers, guides, enough radio sets, and illustrative materials and lack ofrnevaluation system on the success and failures of radio lesson by the classroomrnteachers. Nevertheless, the problem of schools' location, classroom size, andrntimetable in the utilization of educational radio program.s is insignificant in therncase of the three selected primary schools of Addis Ababa. To alleviate of thernproblems which observed in the utiliz ation p rocesses the school comm.unity asrnwell as the concerned educational officials and policy maicers should be givenrnproper attention to fulfill the necessary inputs and troinin.gs for the classroomrnteachers on the way of utilization.
