This study explored teachers' behavior as related to effective teaching practices in 8th, 9th, and 10th grade English classrooms in Jordan. The study also examined some variables that could predict teachers' implementation of effective teaching practices and aimed at finding an estimate of the percentage of students in 8th, 9th, and 10th grades who had problems related to English competency. A total of 152 teachers from 3 districts were asked to respond to questionnaire items, and of these, 148 participated. The results revealed that many teachers who participated in this study were aware of the overall effective teaching practices but did not use some elements of effective teaching in their classrooms. Also, this study revealed that the only variable that predicted teachers' implementation of effective teaching practices in their classrooms was the total time during which they spoke English. Finally, this study revealed from teachers' responses that a large number of students had problems with English competency. Recommendations and suggestions for future research are discussed. Contains 5 tables and 13 references. (Author/JB)
