    Exploring Provision of Oral Feedback During Classroom Interaction in Efl Class: Focus On Grade Twelve in East Shewa Zone
    (Addis Ababa University, 2008-06) Kassa, Legesse; Ayalew, Elizabeth (PhD)
    This paper aim s to review how foreign language teachers provide oral feedback to learners' errors . The ma in aim of t hi s stud y was to find out the types of errors are usual corrected and the kinds of oral feedback teachers provide for learners during class room interaction .Over the last three decades, the role that the provision of oral feedback played in the foreign language learning has been highly a controversial issue. In the field of foreign language learning, however, there growing consensus among the majority of the researchers concerning the significance of error correction. Although the facilitation role of the provision of oral fee back forenames' menorahs empirical support, the claim s regarding its impact on foreign language learning has ye t to be fully or decisively sub substantiated .In order to mouthiness e of the research forward , it is important to examine the issue from the foreign language teaching literature. Hawas Preparatory Government School grad twelve English language teachers were the target of the study. As the number of the subjects is small all grade twelve English language teachers were included in the study. To achieve the objectives se t, necessary data were collectedly ugh classroom observation ,questionnaire and interview The stud y showed that majority of the teachers found oral feedback as an important too l to helplessness to ac hi eve a higher proficiency in foreign language . The investigation indicated that teachers choose to give different kind s of oral feedback in different occasion explicitly or implicitly. The intention of this study has also been to determine what kind s of oral feedback enhance or undermines the chance for learners uptake .The subjects have , among several factors stressed the importance of self correction, implicit and delayed feedback as a means of building learners confidence and to fee l comfortable in learning the foreign language at large.

    Multivariate Assessment of Environmental Effects on Grain Yield and Component Characters of tef (Eragrostis Te!(Zllcc.) Trotter) Genotypes
    (Addis Abeba university, 1997-06) Kassa, Legesse; Hamito, Desta(PhD)
    Tllis study was designed to attain a better understanding of envirollllental factors such as soil and climate that could account for variation in grain yield and component characters of tef genotypes, Furthennore, it was intended to determine the source of variability in the relationships among grain yield and component characters within and among tef genotypes. In the study, 7 and 4 variables of soil and climate, respectively were collected from four locations for the crop seasons 1991/92, 1992/93 and 1993/94. Five plant variables of 12 tef genotypes were also collected for the same locations and crop seasons. Combined analysis of variance, analysis of variance components, canorucal correlation analysis and principal component analysis were used to analyse the data, The results of the study, based on combined analysis of variance and analysis of variance components, revealed that soil and climate variables accounted for a large portion of the variation in grain yield and component characters of tef genotypes. The results of canonical correlation analysis also supported this fact. The results of principal component analysis showed that each of the genotype variables considered in this study had their own share of contribution to the variation within and among genotypes.
