The feedback synchronization of a unified chaotic system;

This paper has,based on Lyapunov stability theory,studied the feedback synchronization of a new single parameter chaos system and produced some simple and realizable controllers when the parameters known and unknown.

Over the past 20 years,the development of writing pedagogy and research has transformed the traditional feedback mode,with teacher written feedback often complemented with peer feedback,oral conferences,and computer-mediated feedback.

This experiment, applying the methods of writing practice, class observation and questionnaire, explores whether the students′ peer feedback——often with more emphasis on language than on content, can be improved both qualitatively and quantitatively after some training.

This study is undertaken during a 16-week semester to investigate the effects of teacher feedback and peer feedback respectively in improving accuracy, fluency and complexity of Chinese college EFL learners writing and explore an effective approach of feedback in.

A Study of the Effects of Peer Feedback on Writing by Chinese EFL Learners at Different Proficiency Levels;

So this paper presents the functions,using methods and principles of peer feedback in college writing class so as to change teachers and students attitude towards peer feedback,incite students writing interest,empower students writing and innovation ability and inspire college English writing instruction.

The results of a questionnaire survey and follow-up interviews show that advanced learners of English have strong inclination to and a high rate of accuracy in peer feedback;students English writing proficiency influences their peer feedback ability;more attention is paid to language than to content and structure in peer feedback.

This paper introduces a collaborative feedback strategy in information retrieval, which combines such technologies as information retrieval (IR), and collaborative feedback.
