    The Effectiveness of Learner Self-Correction of Written Errors in the Efl Classroom
    (Addis Ababa University, 1995-06) Tesfay Solomon ; Hailom Banteyirga
    The present study aimed at finding out which feedback technique(s) to student written errors is/are more effective in helping learners improve their proficiency in written English. In other words, it attempted to explore and describe the process of learning EFL through learner self-correction of written errors with and without teacher clues and direct teacher correction. To do this, a classroom of thirty two Freshman students of AAU were grouped into experimental and control groups based on their scores of the first semester Flen 101A Examination. The experimental group received feedback types that let them selfcorrect their written errors. The control group received direct teacher correction on their writing tasks. The following instruments were employed to collect data. These were: a pre-test and a post-test, nine classroom tasks that were given to students for writing, questionnaires that were administered to members of each group, and interviews were conducted with samples from each group. Errors omitted and opinions given by research subjects on the type of treatments used were collected and analyzed. Comparisons were made to see differences between treatment types and error categories. Means, standard deviations and t-tests were calculated to find out any significant differences between groups and among error categories affected by each treatment. Vi The results obtained showed that self-correction techniques are more effective in helping students learn than the techniques where the teacher gives direct correction. It is recommended, therefore. that teachers should frequently use feedback types that help students to self-correct their written errors. Teacher training programmes should include topics on the use of students focused error treatment where the teacher predominantly plays the role of a facilitator. It is only when the students totally fail to understand and correct their errors that direct feedback is appropriate.

    The Performance of Coffee Marketing in Ethiopia: The Case of IIIubabor and Jimma Zones
    (A.A.U, 1996-06) Tesfay Solomon; Amha Wolday
    During the era of Derg, there had Deen state monopoly in the coffee trade. the state coffee markecing parastatal (Ethiopian Coffee Marketing Corporation ) wa s ope rating based on fixed price arrangements . Once the state parastatal is in place entry t o the coffee trade was difficult . The system has also reduced competition among traders. The long term effect of such a move was .suppression of producer incentive and production. Hence it was apparent to the transitional government of Ethiopia to liberalize the coffee market at all levels. The main objectives of this study are: i ) to describe the coffee marketing system in illubabor and Jimma zones, ii} to assess the structure of coffee marketing in the study area , iii} to measure the efficiency of the coffee marketing system, and iv} to assess the effect of the reform on performance of coffee marketing and to provide basic information which assist policy analysis. The analysis was carried out by using S-C-P approach. The results show that the liberalization policy adopted has achieved certain improvements in the structure and efficiency of the coffee trade. The reform have lifted the licensing barrier and reduced tax levied on coffee trade and license issuance fees. It has also abounded the restrictions imposed on licensing. The reform have also resulted in the free movement of prices. The bivariate correlation analyses shows that prices in the selected markets are highly integrated with the central market. The Timer's indices and the co integration test also show the same result. There are, however, a lot of shortcomings in the structure and inefficiencies in the coffee marketing . There are high market concentration, lack of capital and credit, and restrictions on areas of operation. In some markets there is also poor market information flow among traders. In view of the efficiency, there appears to be significant seasonality and inter - temporal price inefficiency.
