The major objective is to measure the differences between Eastern, Central and Western China. Methods of map presentation, correlation, Lorenz curve, Gini Coefficient and location quotient analysis arc conducted in this study. For convenience, the indicator of regional Internet development is simplified as the number of domain names registered under. CN in each province. The data used are collected from the semi-annual surveys of the Statistical Survey Report on the Intrenet Development in China since 1999. There are several findings: 1) The number of domain names in each province (city) declines gradually from the east to the west. 2) The gap between the highest growth provinces (cities) and the lowest ones is rather large. 3) Although the absolute differences between the eastern, central and western China have been enlarged, the relative differences in each province (city) have remained constant. 4) Provinces (cities) are classified into three types according to location quotient changes, namely, rising type, changeless type and declining type. Compared with industrial and economic growth, Internet sector in the eastern and western China is relatively ascending, while that in the central China is descending. 5) The number of domain names at provincial level is not statistically consistent with GDP.展开更多

This impels opportunities for authentic, inquiry based learning. PBL （problem based learning） is a student centered pedagogy in which students learn about a subject through the experience of problem solving. The goals of PBL are to help the students develop flexible knowledge, effective problem solving skills, self-directed learning, effective collaborative skills and intrinsic motivation. CAPBL （computer assisted problem based learning） has been created to expand the boundaries of the creativity and the creativity of students beyond the four walls of the classroom. In the present study the investigator tested the effectiveness of the CAPBL material in Chemistry for enhancing thinking skills among secondary school students. The sample consisted of 100 secondary school students. The study revealed that the CAPBL material in Chemistry is effective in enhancing thinking skills such as critical thinking, creativity and problem solving.展开更多
