The main purpose of this study was to explore teachers' perception of' active learning and theirrnclassroom practices in English language classes of Meltu Secondary and Preparatory school. Tornachieve this, specific objectives were set giving due emphasis to perception and knowledge ofrnactive learning, teachers' practices in selecting active learning strategies and challenges thosernIrnhamper effective implementation of active learning respectively. It was a descljjztive case studyrnwhich was used in the study. Based on the focus of the research work, the subject of the studyrnwere all English language teachers in the school under study. The method of samJ!ling employedrnwas availability sampling since only four English language teachers who were carrying out thernteaching learning process during the researcher's stay in the school~ere participated in thernstudy. This happened since three of the seven English language teachers in the school were notrnaround during the study. Data were gathered through questionnaire, classroom observation andrn~ ~rnin;;.rview. Data collected through questionnaire were discussed using mean values since usingrnpercentage is misleading. On the other hand, data that were gathered through classroomrnobservation and illlerview were analyzed qualitatively in descriptive words. The findings of thernstudy reveled that the main implementers of active learning (teachers) have a blurred perceptionrnof active learning; as a result, their practices of active learning were low. Among serious factorsrnaffecting implementation of active learning, lack of interest and attitudinal resistance, poorrninstructional facilities and classroom setting, and lack of orientation and training were the majorrnones. Finally, on the basis of the findings, it was recommended that teachers have to be wellrnequipped with basic knowledge and skills that could help in fostering critical thinking andrnproblem solving capacity of the learners. Thus, concerned bodies have to plan for continuousrn{rainings and orientations on the nature, practice and relevance of active learning in Englishrnlanguage classes.
