In the new round of development, the government should not only focus on the development of large enterprises, but also on small enterprises that can grow explosively. According to the growth characteristics of unicorn enterprises, the "Guidelines for the Cultivation of High-Growth Enterprises" should be formulated at the provincial level. On the basis of the clear definition of highgrowth enterprises, the classification criteria are defined. A set of government support mechanisms for enterprise selection, approval and support should be established. In addition, a set of positive support policies should be adopted for different types of enterprises in land use, financing, taxation, technology, talent recruitment and other aspects. 展开更多

To explore the impact of teacher training on the professional identity of primary and secondary school mental health teachers, this study conducted a half-month professional development training program to 54 primary and secondary school mental health teachers, and performed measurement on the professional identity of the teachers in the experimental group and the control group with “Teachers’ Professional Identity Questionnaire”. The result shows that after the training there is a significant improvement in the professional identity of the teachers in the experimental group, and the teachers’ scores on the four dimensions of profession identity: the sense of role, the professional behavioral tendency, the occupational values, and the sense of belonging, all increased significantly. This indicates that the curriculum intervention for the primary and secondary school mental health teachers could effectively improve the teachers’ professional identity. 展开更多

By using stratified random sampling, we selected 2790 primary and middle school teachers as participants. They were from seven regions of China, among them 2278 were valid subjects. Constructed on the basis of anxiety content, the Teachers’ State Anxiety Questionnaire (TSAQ) was used in the investigation. The result of the survey shows that primary and middle school teachers are generally affected by state anxiety;further analysis indicates that the prevalence of state anxiety is relatively higher among male teachers, teachers from key middle schools, teachers working more than 10 hours a day, and teachers loaded with additional task as head teachers. This is directly connected with China’s national situation, teaching envi-ronment, discrepancies in teachers themselves, and their own ability of self-regulation. 展开更多

Background: Primary dysmenorrhea is defined as pelvic pain during menstrual flow in the absence of a pelvic pathology. It is one of the most common gynaecological complaints worldwide and the most common cause of school and work absenteeism among menstruating females. In adolescent students the impact includes reduced attention in class, inability to study at home, school absenteeism among others. Yet these students have to study at the same pace as their peers, raising the concern of whether the problems caused by primary dysmenorrhea have an effect on academic their academic performance. Aim: Determine the prevalence, treatment practices and impact of primary dysmenorrhea on the studies of post-pubertal high school students in Bafoussam. Method: We conducted a cross-sectional descriptive and analytic study design using a two-stage sampling method;the first stage was by convenience to choose the school, and the second stage was consecutive to recruit the students. Data was collected using a semi-structured pretested self-report and anonymous questionnaire. Analysis was done using software IBM<sup><sup>&reg</sup></sup>SPSS statistics version 23 for windows. Categorical variables were summarised in to frequencies and percentages while the comparison of categorical variables was done using a Chi-square test, and a p-value ≤ 0.05 was considered to be statistically significant. Results: our sample size was 898 and the mean age of our respondents (±SD) was 17.6 (±1.6) years. The prevalence of primary dysmenorrhea was 71.9%, with 11.6% mild pain, 52.5% moderate pain and 35.9% severe pain on a visual analogue scale. Over 38% did not attempt pain-relieving measures while others took analgesics, traditional preparations, heat packs among others. Among these students, 39% reported school absenteeism due to pain, other impacts were decreased attention in class, inability to study at home during pain and punishment from school authorities for failing to fulfil certain duties like assignments not done or absenteeism because of pain. Though a greater proportion of students without dysmenorrhea had pass scores than their counterparts, the difference was not statistically significant. Conclusion: Given these findings, school officials may benefit from considering dysmenorrhea in the context of improving their school attendance rates and academic performance of their students. 展开更多

According to the principals of the Course Standard of English for Ordinary Senior Schools, published by China Education Ministry in 2001, the general goal of English curriculum on the basic education stage is to foster the students' cross-cultural awareness, which is to develop their cross-cultural communicative competence. To achieve this goal, most of all, teachers of English at high school must have a good command of cross-cultural pragmatic competence. By looking through papers in various periodicals and the Internet, the writer finds that most of the studies have coped with pragmatic failures of ESL students but few of ESL teachers'. Therefore, this thesis studies the present situation --- how much do schoolteachers of English know about pragmatics? What about their cross-cultural communicative competence? Can they communicate with the native speakers fluently and appropriately? What are the most serious problems among them in pragmatics? What can be done to solve the problems? With all the questions, this research has collected considerable firsthand data and information. Only after the basic situations are known overall, can actions be taken to solve the problems existing in everyday ESL teaching. So this research is necessary and urgent for the present basic English pedagogy. However, since the present writer's ability and research conditions are limited, it is not possible to make a wider investigation in many places. Therefore, the district --- Bameng League, Inner Mongolia, China, is selected as the basic range of the survey, the situation of which is believed to be able to represent the basic educational ones in the poor and remote districts in the north and the west of China where education is more backward. The questionnaire consists of two parts: a table of individual information and a test paper. The former investigates informants' basic information, including the items of name, age, sex, teaching age, title of the technical post, degree, academic career, college or university that they graduated from, working unit, grades for teaching and the others. The latter is the test paper cited from He Ziran and Yan Zhuang (1986), that is, Chinese Students'Pragmatic Failure in English Communication --- Survey of the Pragmatic Difference between Chinese and English. And it contains 48 items, with items of pragmalinguistic and socio-pragmatic competence mixedly arranged. 120 of the questionnaire copies were handed out and 86 are collected, but only 64 are collected. The survey covers over 10 high schools in all the 7 banners of Bameng League, including two autonomous region-class key schools and five other league-class key schools. After the investigation, the present writer carefully corrects, marks, arranges, summarizes and analyzes the questionnaire, and obtains plenty of firsthand data and information. Then some conclusions have been drawn based on the data analysis. The result of the survey shows that linguistic competence is not equal to pragmatic competence, that ESL high school English teachers may use English rather fluently, without many mistakes in vocabulary and grammar,but it does not necessarily mean that they can use the target language appropriately to communicate with native speakers without pragmatic failures, and that the informants' knowledge of pragmatics and their pragmatic competence are rather poor. As a result, improving their knowledge and competence in pragmatics becomes a very necessary and urgent task to develop the quality of ELT in basic educational stages. In order to solve the above problems, the writer makes some suggestions as follows: (1) Pragmatics should be required as an essential course for the English majors in colleges and universities, especially in normal colleges and universities; (2) In-service high school English teachers must study courses of pragmatics and cross-cultural communication; (3) In some poor and remote districts, if educational conditions don't permit, textbooks of pragmatics and cross-cultural communication must be handed out to the high school English teachers who can study by themselves, then tests are regularly held for them and certificates will be given to those who have passed the tests; (4) In some developed districts, if conditions permit, English teachers can be sent abroad to English-speaking countries for further education in order to have a good command of the English language in the authentic contexts; (5) Modern multiple medias, such as VCD or DVD videos, TV or radio programs, the Internet, should be widely and frequently applied to training teachers; (6) More native language teachers and experts from English-speaking countries must be invited to high schools to train teachers of English. 展开更多

For English education primary school,English vocabulary teaching should be attach importance to because in the traditional class of English vocabulary teaching,teachers just fill young minds with knowledge points of each word in a 35-minute class yet fail to lay emphasis of learners’meaningful learning and autonomic learning as well as their very limited attention spans.To support traditional English vocabulary teaching classes,the research proposes the theme-based English vocabulary micro-lectures designed on the basis of experiential learning theory and constructivist learning theory as well as the analyses of target users of high-level students in the primary school.After application of the micro-lectures into practice,the research assesses the effect of the micro-lectures on the learners and then makes suggestions for design principles of theme-based vocabulary micro-lectures about selection of contents and vocabulary themes,supplementary teaching activities and teacher interaction in the micro-lectures for high-level students in the primary school.Also,the designers should make multi-level English vocabulary micro-lectures according to learners’English proficiency and increase repetition rates of vocabularies in the micro-lectures. 展开更多

In view of a series of challenges since Task-Based Language Teaching(TBLT) was introduced into China, we interviewed 14 front-line teachers in primary and secondary schools about their viewpoints and classroom strategies of TBLT. The results show teachers’ willingness to use TBLT. They adopt flexible teaching procedures, apply TBLT creatively, and explore task-based language assessment. The authors argue for inclusive non-doctrinaire approaches to TBLT, and propose to construct localized TBLT theory and practice with Chinese characteristics. 展开更多
