Since the researchers did not have any control over randomization of students and it was considered as one of the features of experimental method, this study is not a true experimental method. This method is called Intact Group Study. In this research there were experimental and control groups. The age range of the learners in both groups was between 19 to 22; the age range difference was so limited that we could neglect the difference concem. The number of students in both groups was closely the same. One of these groups received question-generation reading strategy instruction and the other group---control group--did not receive this instruction. Participants in both groups studied a task-based course book called New Interchange 3 by Richards (2005). They studied the last eight units of this book during a whole term. The instruction was the same for both groups except for the reading parts. Participants in experimental group were taught how to generate questions as being linked to the main ideas of the text they were reading. They were also given feedback on the correctness of the questions they generated. Then they answered the follow-up questions However, participants in control group received a traditional method of reading for comprehension; they read the text on their own and answered the follow-up questions. Of course both groups enjoyed a warm-up before reading each text. The statistical independent group T-test of the reading comprehension posttest showed that participants in the experimental group performed better than the students in the control group展开更多

The development of learner autonomy depends largely on teacher autonomy. Teacher autonomy is also one of the most effective ways to support teachers in their classroom practice, as well as to improve and expand their professional preparation and practices. Apart from that, the research of teacher autonomy at different phases of teachers' professional development may provide insight into how to strengthen their autonomy capability and to better understand the differences in teachers' development at different stages. The current study aims to explore the different level of how university novice and proficient English teachers see themselves as autonomous practitioners on the five dimensions of teacher autonomy: teaching autonomy, assessment autonomy, school management autonomy, professional development autonomy, and curriculum development autonomy. In addition, it proposes coping strategies to facilitate the development of teacher autonomy, which may shed some light on cultivating teacher autonomy for teachers at different developing stages, development of expertise, and teacher education.展开更多

As a result of its association with racism during the Apartheid regime in South Africa, the term was heavily politicized and lost its original meaning to acquire racist connotations. In South Africa, the names "African(s)" or "Black(s)" are used as substitutes for the stigmatized name "Bantu(s)" with reference to the Bantu speaking peoples and their languages. This research investigates the use of the words, "Africans" and "Blacks" to assess their suitability as replacements for the word "Bantu". An intensive outline of the classification of the languages of Africa is given to authenticate the basic meaning of these classificatory terms, especially the term "Bantu"展开更多

Previous research has shown certain factors would increase class participation from educators' view, while in this paper, a survey was designed to find out what students themselves think would motivate them to speak more in class. The survey was given to a group of grade 9 students in a middle school in China. Among the elements that were selected in the survey, the result shows students tend to favor a friendly relationship with the teacher, a warm learning atmosphere, a lively teaching style, and variety interesting learning activities as well as supplemental materials in terms of more verbal participation. The finding reinforces the previous studies on these factors' positive roles in promoting students' motivation to speak more. This paper is expected to serve as a resource for professionals who work in the relevant area and draw more attention from educators, in particular those in the China context, on this topic展开更多

The universities and the industries are dependent on each other as the university's role is to produce human capitals to work at the industries, and the industries on the other hand need human capitals to run their business. However, this kind of dependency could raise issues that cause difficulties for both parties if the relationship is not checked and balanced from time to time. The universities should be aware of the industries' changing needs as time changes. Hence the programmes that they offer to their students should take into consideration the industries' needs. This research was to identify the current practices of the university-industry engagement, to appraise the factors contributing to the effectiveness of the university-industry engagement involving UMP (Universiti Malaysia Pahang) and the identified industries, to map the prospects and challenges that UMP faces in the university-industry engagement and to propose the best approaches that the university could engage to provide high class human capitals to work at the industries. This research employed a survey in the form of interviews and expert group discussions. The results show that there is still a mismatch in the university-industry engagement. The representatives from the industries felt that they should be actively involved in the university's activities, especially in teaching, learning and industrial training for students.
