    (Addis Ababa University, 2024-08) Abera Belay; Hailu Gutema
    The objective of this study was to assess the practice of cooperative learning in teaching reading comprehension grade nine students in English language classroom. The method of the study was employed by descriptive types of research design which were carried out through qualitative methods. The sample size of the study was 189 students for the total population of 756 students were selected through purposive sampling method. Eighteen teachers were purposively selected for questionnaire and classroom observation. The data were gathered through classroom observation and questionnaire. The classroom observation was intended to assess and identify the ways of practicing cooperative learning in teaching reading comprehension. The students’ questionnaire was intended to assess the attitude of grade nine students towards cooperative learning in teaching reading. The teacher questionnaire was planned to check the awareness or knowledge, and attitude of teachers and the factors that affect the practice of cooperative learning in teaching reading comprehension in language classroom as well as techniques they applied in reading comprehension. The data gathered from classroom observation and questionnaires were analyzed using qualitative method. The findings of the study revealed that there were some factors that affected cooperative learning in teaching reading comprehension for instance lack of students desire or interest, level of difficulty, knowledge of text type, content difficulty and large class size.

    Physicochemical, Antimicrobial, Antioxidant and Sensory Characterization of Belete-Gera Forest Honey, Jimma, Ethiopia
    (Addis Ababa University, 2018-11) Tekleweyni GlMikael; Abera Belay; Zelalem Debebe
    The study aimed to investigate the quality of honey based On botanical origin, physicochemical, antimicrobial, antioxidant and sem'olY properties collected ./i'om Belete -Cera forest, Jimma, Ethiopia. A total fol'/y eight samples honey samples were collectedji'om Jimma- Ethiopia and categorized into seven mono/loral honey I.Ising melissopalynology. Sugars (/i'uctose, glucose, suc/'Ose, maltose) and hydroxylmethy/iu/ilral were investigated using high per/ilrmance liquid chromatography and moisture, pH, acidity, ash, au., conductivity and colour were analysed using harmonized method of the international honey commission. The antioxidant content (phenol, flavonoid) and antioxidant activity (2, 2 -Diphenyl I-picryl hydrazyl assay, ferric reducing antioxidant power, Peroxide Radical scavenging activitie.l) were analysed using UV. Ipectrophotometer. The antimicrobial properties were analysed using disc diffi.lsion and sensruy acceptability based on seven hedonic scale.
