There is only one author listed in the article. There should be three authors, in the following order: Ghina Al-Badawi (Khalil Shehab Makassed School), Ghazi Ghaith (Education Department, American University of Beirut), and Kassim Shaaban (English Department, American University of Beirut). (The following abstract of the original article appeared in record 2006-20625-001). This study investigated the effects of the Jigsaw II cooperative learning (CL) model and whole class instruction in improving learners' reading comprehension, vocabulary acquisition, and motivation to read. Forty-four grade five English as a foreign language learners participated in the study, and a posttest-only control group experimental design was employed. The results did not indicate any statistically significant differences between the control and experimental group on the dependent variables of reading comprehension and vocabulary acquisition. However, the results revealed statistically significant differences in favor of the experimental group on the dependent variable of motivation to read and its dimensions, the value of reading, and reading self-concept. The pedagogical implications of the findings and suggestions for further research are discussed.
