We compute the rst N coeecients of the reciprocal r(x) of a given polynomial p(x), (r(x)p(x) = 1 mod x N , p(0) 6 = 0), by using, under the PRAM arithmetic models , O(h log N) time-steps and O((N=h)(1 + 2 ?h log (h) N)) processors, for any h, h = 1; 2; : : : ; log N, provided that O(log m) steps and m processors suuce to perform DFT on m points and that log (0)

This research aims to investigate whether the students who are taught reading in descriptive text through Reciprocal Teaching Method achieve better ability than those Conventional and explain about advantages that will get when using improving students’ comprehension . The design of this study was quasi experimental, control class, pretest-posttest because it conducted two classrooms. subjects ...

About Reciprocal Teaching In reciprocal teaching, students and teachers talk to one another about the meaning of text, taking turns leading the dialogue The dialogue is struc tured to incorporate four strategies: generating questions about the con tent, summarizing the content, clarify ing points, and predicting upcoming content from cues in the text or from prior knowledge of the topic (see bo...

This study was an attempt to shed light on the relationship between perceptual learning styles and perceptual teaching styles of Iranian EFL learners and teachers. It further investigated the relationship between perceptual learning style and the age, gender, and proficiency of Iranian EFL learners. A total of 112 students and 23 teachers participated in this study. The data was collected using...

In face-to-face instruction of Reciprocal Teaching (RT), students’ reading processes and dialogues with their peers are hardly observed. As a result, the teacher has few clues to identify students’ learning difficulties and provide further scaffoldings. To record students’ reading processes and enhance their comprehension, this study reports on the design of an online reciprocal teaching and le...
