RESUMO
Objective@#To understand sleep quarity among primary and middle school students in Shenzhen City, so as to provide data support for sleeping quality improvement.@*Methods@#A survey was conducted among 8 742 children selected from two 12 year schools in Longhua District of Shenzhen City, by purposive sampling method from December 22, 2020 to January 15, 2021. The general information was investigated with the self designed questionnaire, and sleep disturbance was investigated and evaluated with the Sleep Disturbance Scale for Children (SDSC). And Chi square test was applied for data analysis.@*Results@#About 47.61 % of primary and middle school students in Shenzhen City reported sleep disturbance, 10.84% of students had moderate to severe sleep disturbance. The overall rate of sleep disturbance and moderate and to severe sleep disturbance among primary school students (48.03%, 10.04%), junior middle schools (45.89%, 11.30%), senior middle schools (52.61%, 16.83%) were found of statistically significant differences ( χ 2=8.89, 27.05, P <0.05). The time to fall asleep for primary school students, junior school students and senior school students at night during the study period were 22:00-23:00 (90.35%), 22:00-23:00 (62.37%), and 23:00-01:00 (61.44%), respectively, and the time to fall asleep of the different stages students were found of statistically significant differences ( χ 2=1 470.17, P <0.01). About 41.04% of students could fall asleep within 15 minutes and 50.57% could fall asleep within 15 to 30 minutes, and the differences in the latency for different stages students to fall asleep at night were of statistical significance ( χ 2=82.92, P <0.01); 8.03% of primary and middle school students had a night sleep time of over 9 hours, and 45.97 % had a night sleep time of 8-9 hours, and the differences in the night sleep time among different stages students were of statistical significance ( χ 2=1 292.86, P <0.01).@*Conclusions@#The main sleep problems among primary and secondary school students in Shenzhen City are insufficient sleep and poor sleep quality. The relevant departments should emphasize the sleep health education among children and their parents, so as to improve their sleep quality.
RESUMO
The article analyzed the problems in the clinical practice evaluation of eight-year program and illuminate the characteristics of the process evaluation based on Sojump , and pointed out that the implementation of the process evaluation into the clinical practice evaluation is the inevitable trend in the development of clinical teaching. Combining with the case study of eight-year program in West China Medical School, the article described the implementation of process evaluation in detail. On the basis of the Sojump as the platform for evaluation, the evaluation questionnaire according to the practice rotary table has con-ducted, and the"evaluation-feedback-evaluation-feedback"model had been set up. The application of pro-cess evaluation has promoted the effect of the clinical teaching. However, in the following practice, it is necessary to solve the problems as the evaluation of each teacher can't be specific and students' awareness and cognition of teaching evaluation can't be guaranteed, etc.
RESUMO
West China School of Medicine employs graduates as teaching assistants to help teachers implement the mode of "inquiry-based small class" in medical courses.Under the guidance of course directors and teachers,graduate assistants help the "lecture group discussion" and the implementation of process evaluation.Meanwhile,they enrich the useful teaching resource on the course web sites and help to develop the students' self-study ability.Graduate assistants build a more harmonious teacher-student relationship and effectively enhance teaching quality and efficiency of inquiry-small course.
