Countries have employed different alternative models of schooling in their school systems andrnalso altered from one to the other in times, most commonly from half-day to full-day schooling.rnIn the case of Ethiopia, Addis Ababa City Administration has launched its effort to realize suchrnalteration in primwy schools since academic year 1999E.C. With scarcity of resources of therncountry, employing fiill-day schooling would have significant implications on the provisionsrnand achievement of primary schooling. Taking these all into account, this study was carriedrnout to assess the major issues and problems of fiill-day schooling in second cycle primaryrnschools of Addis Ababa. It surveyed the benefits and challenging factors of the schooling modelrnalong with its implications on the internal efficiency and educational equity in schooling. Inrnorder to attain its objective, descriptive survey method was employed. The study was conductedrnin six governmental primary schools sampled from two sub-cities of Addis Ababa; namely,rnKirkos and Akaki-Kaliti. Sub-cities, schools, teachers and students were selected using multistagernsampling techniques. The main sources of the data were teachers, students, principals,rnParents-Teachers Association (PTA) representatives and Kebele 's educational team leaders.rnQuestionnaires were administered to 65 teachers and 273 students sampledfrom the respectivernschools. Semi-structured interviews were conducted with a principal and a PTA representativernof each sampled school and two educational team leaders from the sub-cities selected. Besides,rndocument review and direct school observation were also conducted to secure additionalrninformation on the basic questions of the study. The sequential exploratory research designrnwas employed to collect and analyze quantitative data first, qualitative data next and finally torninterpret the entire analysis of both types of data. Frequency count, percentage and mean werernused to analyze the quantitative data through the use of Statistical Package for Social Studiesrn(SPSS) for Windows. One-sample T-test was used to compare class sizes and weekly teachingrnloads of respondents to the target set by Addis Ababa Education Bureau and Ministry ofrnEducation (MOE). The qualitative data were analyzed using focus by question approach.rnAccordingly, the major findings of the study revealed that lengthening school day wasrnconsidered as the least determinant of effectiveness in the schools, three-fourth of thernrespondents confirmed that fUll-day schooling contributed to better students' behaviors andrnperformance, the majority of parents have very narrowed view on the benefits of the schooling,rnthe schooling has contributed to increase in drop-out rate of 5 -8 grade students in the schools,rnhalf of the teacher respondents rated the effect of the schooling as "high" to exclude childrenrnwith economic problems from school and the practices of the schooling were found to bernentangled with economic problems of students and inadequacy of school facilities and servicesrnand as a result, increased students' absenteeism and truancy. On the basis of the conclusionsrndrawn from these findings, the researcher recommended that parental awareness andrninvolvement need to be enhanced, students with economic problems should be supported eitherrnthrough school feeding program or material supports, mounted political, financial andrnmaterial commitment is required to improve school facilities and more importantly, it is highlyrncommendable to investigate the implications that the schooling model can have on achievingrnthe development goals of the country.
