    The Attitude of Teacher-Trainees toward Education Courses: The Case of Addis Ababa University
    (Addis Ababa University, 1996-06) Kebede, Belete; Asgedom, Amare (PhD)
    The purpose of this study was two fold, in view of the central importance of the professional educa tion courses in the training and education of secondary teachers. First, to identify the attitude of the graduating student - teachers of the Addis Ababa Uni versi ty toward educa tion courses. Second, to explore the factors related to the studen t-teachers ' coursea tti tude. A fifty-four item attitude questionnaire based upon the Likert Scale was administered to 163 survey population. The data were analysed and interpreted using chi- squire and correlation statistics. The iden tified trainees ' overall course - a t t i tude was analysed in rela tion to the trai nees' characteristics and regard for the teaching profession; and in relation to the trainees' evaluations of factors related to the courses and the instructors' quality of teaching . The resul t of the study revealed a non significant favorable attitude toward education courses. However, the identified attitude was found to be irrespective of the sex, major area, region of secondary education and CGPA of the student-teachers. The graduating student-teachers indicated that the courses lack fair balance between theory and practice, duplicated interms of contents, and less stimulant toward teaching. On the other-hand, the instructors' quali t ies o f teaching were rated unfavorably, in general. Teaching profession was accorded a high regard by one half, and a l ow regard by the other half, of the sUbjects . In the present study, the trainees' characteristics were found to be of little help to explain course-attitude. But, factors related to the courses, the instructors and the trainees' regard for the teaching profession were identified to have a direct association with the student-teachers' attitude toward education courses.

    Ecological Study of the Shrubland Vegetation around Ambo, West Shewa Zone of Oromia National Regional State, Central Ethiopia
    (Addis Ababa University, 2012-06) Kebede, Belete; Woldu, Zerihun (Professor)
    The study area is located around Ambo, West Shewa Zone of Oromia Regional State. This study was carried out with the aim of compiling floristic composition, population structure and community types. Fifty two, 20 m x 20 m quadrats were selected and all the plants in the quadrats were recorded. The cover abundance values were estimated. DBH, height, and density count for woody species in all the quadrats were registered. A total of 110 species belonging to 98 genera and 48 families were recorded from 52 sample plots and identified at the National Herbarium (ETH), Addis Ababa University. The Asteraceae family was represented by the highest number of species (16) followed by Fabaceae (13) and Poaceae (8). Five community types were identified and described. The plant communities were named after two or three of the dominant species and/or characteristic species selected by their synoptic value. The plant community differed in species diversity, frequency of occurrence and botanical composition of species. The Rosa abyssinica- Galium aparinoides community type had the highest species diversities whereas Vernonia amygdalin-Erythrina brucei-Juniperus procera and Bidens pilosa - Microlepia strigosa - Capparis tomentosa communities had the lowest. Shannon-Wiener diversity indices were computed to measure species diversity and it revealed that species diversity is high in communities 1, 5, 4, 2 and 3 respectively. This is probably due to high rate of disturbance in the communities. The natural environment is under threat from various farming and grazing practices. Based on the result of the study, continuous discussion between local communities and various stakeholders as well as detailed ecological studies were recommended Keywords/phrases: Cluster analysis, Diversity, Dominant species, Floristic composition, Vegetation, Vegetation structure
