In which, the partially matched cross over (PMX) and reverse mutation are used for the sequence coding, whereas the arithmetic crossover and heteropic mutation are used for the decimal coding. In addition, the relationship between production scale and production cost is analyzed and the maximum profit is always a trade-off of the production scale and production cost. Two examples are solved to demonstrate the effectiveness of the method.展开更多

This approach is expected to foster the students＇ design skills in design studios. The approach is an educational tool for tutors that could guide the students and increase their creativity in their design. It considers the concepts and the practice of digital architectural design that influence architectural education. The approach is a catalyst for creativity, experimentation, critical thinking and the sustained growth of creative communities. The core of design studio is the notions, methods and skills of digital architectural design. The instruments used for this research was an investigation that made for the work of the fourth year students designs at the architectural department at University of Jordan, by testing design process and product of students＇ work： first using manual skills, and then using computer-aided programs. The results revealed that the computer-based design approach was able to foster students＇ design skills as well as to develop their creativity in design. Ninety-one percent of 44 students were found improved in design process using computer-based approach that depends on computer programs. This was done in design studio by improving students＇ way of thinking, developing their abilities to direct their own learning and pushing them for new definitions in developing their future work.展开更多

The EAP course could not only enhance the communication skills of the international students, but also improve their knowledge of English grammar, vocabulary, spelling, sentence structure and composition skills. The purpose of this paper is to analyze the useful teaching method teacher used in class, and help different students improving their English skills.展开更多

It highlights that school teachers need to acknowledge students＇ preferred learning methods, especially those of minority backgrounds like the Samoan participants in this investigation. A detailed exploration of the experiences of students in two HSGs finds that while students and their families place a high priority on learning, their cultural practices are not compatible with standard Western learning approaches. The HSGs provided a social space in which students could ask the teacher questions without fear of appearing foolish, in which they could apply themselves to study. It provided a physical study space away from the demands some Samoan families place on their young people, and it provided a cultural space in which the students could learn according to fa＇aSamoa （traditional values and beliefs）. This research makes a contribution to an understanding of the motivations of Melbourne-based Samoan students to learn, of what concerns them, and of impediments to their educational success. It also offers insight into the benefits that set up a specific space for students offers, when its specific intent is influencing the merging of Samoan and Western ideas to further learning.展开更多
