(Addis Ababa University, 2014-10-20) Ananiya Abebe; Kassa Michael
The purpose of this study was to assess mathematics learning and achievement of
Students with hearing impairment. Descriptive survey research design was used for this study. The study was carried out in Menelik II preparatory school. The study sample
Comprised 4 mathematics teachers, 4 interpreters and 40 students with hearing
impairment. Data was collected by use of questionnaires, observation and document
analysis. It was analyzed and presented using descriptive statistics (frequency
distribution, mean score, percentages and standard deviation) and t-test and multiple
regressions. This study found out that :- most of the respondents were a profound hearing
impaired without other family members with hearing impairment, some of the
respondents/students hear conversation very slightly and a few of them hear sound very
slightly, most of the respondents' parents were with no formal education except for some
who were certificate or diploma and degree holders, teachers do not use an appropriate
methods of teaching, time on task was found to be inadequate, teachers are in trouble to
use sign language, teachers never covered the syllabus content in the stipulated time and
students with hearing impairment had low mathematics achievement. This study
recommends: to give training on methods of teaching, to use tutorial program, to use
more instructional time and to give sign language training.
Ethiopia’s Accession to the East African Community: Legal Challenges, Opportunities, and Integration Lessons
(Addis Ababa University, 2025-11-01) Gemechis Mekonnen; Zelalem Mogessie
This study explores the legal and institutional implications of Ethiopia’s potential accession to the East African Community (EAC). It analyzes the EAC’s legal framework such as the EAC treaty, Customs Union and Common Market Protocol against Ethiopia’s existing legal framework. Drawing comparative lessons from Poland’s accession to European Union and Vietnam’s integration to ASEAN, the research identifies key legal reforms, institutional adjustments, and phased implementation strategies essential for successful integration. The study also focus on evaluating the challenges Ethiopia might face, such as those related to trade liberalization, competition, and regulatory harmonization, and suggests mechanisms to mitigate potential drawbacks. Additionally, it highlights the opportunities, including expanded market access and regional influence. The study employs a doctrinal and comparative methodology to provide practical policy recommendations for Ethiopia’s effective and strategic entry into the EAC.
The Effect of Integrating Instructional Technology into Mathematics Classroom on Trainees' Pedagogy Content Knowledge at Arbaminch College of teachers' education (SNNPR)
(Addis Ababa University, 2011-06-20) Tamagn Haile; Solomon Areaya
The main purpose of this study was to investigate the effect of integrating instructional technology into mathematics classroom on trainees' Pedagogical Content Knowledge at Arbaminch College of teachers' education (SNNPR). To achieve the above purpose, a quasi-experimental design in general and a pretest-posttest non-equivalent group design in particular was used. The required data was collected using a pretest, posttest and students' questionnaire. The subjects of this study were first year Mathematics and natural science regular (MNSR) cluster diploma program trainees. These trainees were selected purposefully as intact groups. In order to increase the validity and reliability of the data collected, all the instruments listed above were first piloted in similar groups before the administration of the actual instrument. The data collected through questionnaire based on the five point Likert scale was analyzed using a descriptive statistics together with a chi-square test of independence. On the other hand, data collected using achievement test was analyzed using student 's t-test, one-way ANOVA, ANCOVA and regression analysis using SPSS 15.0 and Fathom 2.1. The analysis of achievement test revealed a significant mean difference (P<0.05) between pretest and posttest scores of high and medium achievers among the experimental and comparison groups. However, this was not true for low achievers. The same analysis also showed a significant mean difference between male trainees among the experimental and comparison group. However, this is not true in the case of female trainees. The analysis of data through questionnaire also indicates a significant difference between the pre-and-post responses of trainees PCK after the intervention. Thus in this study it is strongly recommended that effective mathematics teaching-learning process in teacher education colleges should incorporate the use of instructional technology to enhance students' mathematics achievement and to develop their pedagogy content knowledge
