Teachers use the advantages ＆modem information technology can create a good teaching situation, optimize the classroom teaching process, cultivate student＇ s self-learning ability, and improve the effectiveness of vocational English classroom teaching. The purpose of college English teaching is to enable students to master certain basic knowledge and skills in English, with some listening, speaking, reading, writing, translation ability, a simple verbal and written communication in daily activities and foreign business activities. Modem information technology provides a strong tecbaaical support to achieve this goal. Multimedia teaching methods widely used in teaching activities to vocational English class have brought a series of profound changes. Teachers using modem educational teclmology to fully develop learning resources, build new teaching model, which make vocational English classroom full of vigor and vitality.展开更多

In the era of globalization, multicultural education has been important for all people around the world ever since their early childhood. Art is a necessary approach for young children to learn the world and expand their vision. It is also a good path for young children to learn different cultures, to foster respect for them, to enjoy cultures different from themselves, and to improve their skills for interacting with people from other cultural backgrounds. The main purposes of this article are to discuss the reason why art can be a potential approach to learning multi-cultural education and how an art approach can nourish young children＇s multi-cultural equipment. To reach these two purposes, literature review and case study analysis are adopted. There are five sections in this article. The first section introduces the background of this study. The second section explores the relation between art and multi-culture. The third section discusses how to use art in an antibias way and respect different cultures for young children. The fourth section analyzes two cases in order to know how to design curriculum, practice teaching and evaluate the efforts of multicultural education. The finally section is about the conclusion and some suggestions.展开更多

Each source signal is extracted in two stages: a filtered version of the source signal is first obtained by solving the generalized eigenvalue problem, which is then followed by a single channel blind deconvolution based on ensemble learning. Simulation demonstrates the capability of the approach to perform efficient mutichannel blind deconvolution.展开更多

This study was designed to examine the behaviors of adolescent pedestrians in southern Iran. Methods： This is a descriptive analytical cross-sectional study. The study population consisted of high school students in Shiraz, capital city of Fars Province, Iran. Five hundred and sixteen students were selected by multi-stage sampling. Data were collected by the use of three questionnaires, which included Persian copies of adolescent road user behavior questionnaire （ARBQ）, Duke University Religious Index （DUREL）, as well as the context and independent variables questionnaire. Results： The results showed that a decrease in dangerous behaviors on the road resulted in an increase in respondents＇ intrinsic religiosity. Also, engagement in unsafe crossing behavior in the road decreased with increasing respondents＇ intrinsic religiosity. Another finding showed that female students were less involved in dangerous play and planned protective behaviors on the road. Conclusion： Findings clearly indicate that intrinsic religiosity has a significant role in reducing the risky road behaviors of students. Hence, religion may improve road safety in school students＇ road behavior in Iran.展开更多
