First, a measurement criterion for the total variation of multivariate qualitycharacteristics is introduced by the result of information theory. Then the implementation procedurein the robust design is presented. After that, a simulation example from a practical industrialprocess is provided. Finally, some comments and further work are discussed.展开更多

This report presents the processes of CL implemented in two English intensive reading courses at a Chinese university. The purpose is to arouse the students＇ awareness of working in groups in their English reading classroom and to enhance their reading comprehension at tertiary level. The results show that students can adapt to small group work when they realize the benefits brought to them. Although positive effectiveness of CL is prevalent at any levels in educational contexts, benefits of CL on ESL are not deeply cultivated as expected, particularly for Chinese learners of English and some problems can also be found in implementing CL. As the emphasis of curriculum of English Language Teaching （ELT） in China has been on developing students＇ competence in communication in English, it is necessary for teachers to adopt CL in classroom instructions rather than teacher-centered approaches.展开更多

First, a measurement criterion for the total variation of multivariate qualitycharacteristics is introduced by the result of information theory.
