The purpose oJ this study was to investigate the effort oj grade ten English teachers to motivaternand increase students' participation in the English classes because motivation is believed to bernthe most important and decisive Jactor to bring a relatively permanent change on the students'rnacademic perJormances.rnIn order to collect valid and relevant inJormation about the study, questionnaire Jor thernstudents, classroom observation and an interview Jor the English teachers were conducted Sixtyrnstudents from eight sections oj grade ten in 2003 and Jour English teachers who have beenrnteaching the sample students were selected as a sample. After the selection, the students andrnteachers were made to give their responses about the effort oJ their teachers to motivate andrnincrease students ' participation in the English lessons. 21 items oJ th e questionnaire Jor thernstudents were administered Moreover, Jour English teachers were interviewed Furthermor e,rneach English teacher was observed three tim es. Finally, quantitati ve and qualitative technique srnwere used to analyze th e data. The data collected through the actual classroom observation, th erninterview and the open ended items oJthe questionnaire were analyzed qualitatively where as th erndata gathered via th e closed-ended items of the students' questionnaire was analyzedrnquantitatively.rnThe results oJ the study showed that, having created a good relationship with th e students so asrnto motivate and increase students' participation in the English lessons, the teachers tried tornorganize and manage the class room in order to enable learners carry out effective teachingrnlearning process. Though they didn't encourage learners to evaluate themselves by usingrnappropriate teaching aids and by giving additional activities and Jurther practices so as to helprnstudents who need due attention., they did an undeniable and encouraging job with great effortrnby providing more opportunities Jor students to participate actively. As a result, most studentsrnwere motivated and aroused to learn their lessons properly and in an interesting way.rnFurthermore, most teachers used rewards such as pen, pencil, exercise books etc and also theyrnused praise words such as excellent, bravo, great, keep it up etc. in order to motivate increasernand attract the students' attention towards actively following their lessons. However, somernteachers were not in a good position by providing such opportunities to bring a meaningfulrnchange on students' participation so as to help students who need due attention. Since theirrnefJort to do more was less effective, a number of students' effort to in crea se th eir participationrntowards actively Jollowing their le ssons so as to achieve the intended goal was minimum . Inrngeneral, though the teach ers' effort in th e selected school was some how good and effective, theyrnshould coopera ti vely work hard so as to achieve the desired intended goals because somernteachers' effort to teach students in th e English lessons so as to achieve the intended goal wasrnnot as such effective and satisJactory.
