In spite of the popularity of mobile dictionaries among students, research on the effect of this app on students’language learning, especially focusing on the students from vocational school in rural area, is still scarce. So the purpose ofthe current study is probing into the effect of using mobile dictionaries on lower-intermediate students’ language learning, focusingon the students from vocational school in rural areas, in contrast to using printed dictionaries. This proposal is arranged as follows:section one presents the research background; section two reviews literatures; section three provides research problems and research design; section four presents data analysis and anticipated results. This proposal ends with conclusions. In term of researchaims, a mixed method of quantitative and qualitative will be applied with the main aim of probing the effect of using mobile dictionaries on students’ English learning and the opinions of students’on using the mobile dictionaries in English learning. Researchmethods in the form of quasi-experimental pre-and post-tests, questionnaires, interview will be undertaken to collect data.展开更多

On the basis of expounding the status quo of idle school buildings and public services in rural areas of Enshi City,the following recommendations are put forward: using the idle school buildings to develop rural public education; using the idle school buildings to develop rural public health and medical services; using the idle school buildings to develop public cultural undertakings in rural areas; using the idle school buildings to develop social security undertakings in rural areas.展开更多

Methods Data sets of boys and girls at the age of 7-18 years collected from the series of Chinese national surveillance on students' constitution and health (CNSSCH) between 1985 and 2000 were divided into five socioeconomic and demographic groups, while BMI classification reference proposed by Working Group on Obesity in China (WGOC) was used as screening reference to calculate the prevalence and trends of overweight/obesity in these groups. Results In 2000, the prevalence of obesity and overweight in boys aged 7-18 years was 11.3% and 6.5% in Beijing, 13.2% and 4.9% in Shanghai, 9.9% and 4.5% in coastal big cities, and 5.8% and 2.0% in coastal medium/small-sized cities, respectively, while the prevalence of of obesity and overweight in girls of the same age group was 8.2% and 3.7% in Beijing, 7.3% and 2.6% in Shanghai, 5.9% and 2.8% in coastal big cities, and 4.8% and 1.7% in coastal medium/small-sized cities, respectively. The prevalence of obesity was low in most of the inland cities at an early stage of epidemic overweight. The epidemic manifested a gradient distribution in groups, which was closely related to status (SES) of the study population. However, a dramatic and steady increasing trend was witnessed among all sex-age subgroups in the five urban groups, and such a trend was stronger in boys than in girls, and much stronger in children than in adolescents. Conclusion Although China is at an early stage of epidemic obesity by and large, the prevalence of obesity in her urban population, particularly in coastal big cities has reached the average level of developed countries. The increasing trend has been rapid since early 1990s, and the increments in obesity and overweight are exceptionally high. The prospect of epidemic obesity in China is in no way optimistic. Therefore, preventive program should be focused on the improvement of the balance between caloric intake and energy expenditure, and interventions aimed at changing children's life styles.展开更多

Meta-cognition strategy training is helpful for the language learner to acknowledge how to study, how to monitor, evaluating and adjusting one's study process. This research tried to study the present situation of meta-cognitive strategy usage status of students from minority areas base on the data collected by the questionnaire.展开更多
