Somatic symptoms and concern regarding COVID-19 among Chinese college and primary school students: A cross-sectional survey

To analyze and describe the status and characteristics of using electronic screens of primary and middle school students in China from 2016 to 2017. From 2016 to 2017, 275 monitoring points were selected from 31 provinces in China, and 280 primary and middle school students were selected from each monitoring point to complete the survey. Using the suggestion from "Healthy China Initiative(2019-2030)"of which the screen time of primary and middle school students should be less than one hour per day as the standard. A total of 74 314 primary and secondary school students(except grade 9 and grade 12) were included in this study. Among them, there were 37 147 boys(50.0%) and 37 167 girls(50.0%); 44 612 pupils(60.0%), 14 858 junior school students(20.0%), and 14 844 senior high school students(20.0%); 38 995(52.5%) rural students and 35 319(47.5%) urban students; 53 287 boarding students(71.7%) and 20 537 day students(27.6%). From 2016 to 2017, the average daily screen time of Chinese primary school students was 1.45 hours, M(P25, P75) was 1.14(0.57, 1.93) h. That of junior high school students was 1.92 hours, M(P25, P75) was 1.43(0.71, 2.48) h. That of senior high school students was 2.37 hours, M(P25, P75) was 1.71(0.90, 3.02) h. The average daily screen time qualified rates of primary school, junior high and senior high school students were 46.1%, 37.1% and 27.7%, respectively. From 2016 to 2017, the most used electronic screen products of primary school students in China were TV/videos(62%), followed by mobile phones(21%). Junior high school students spent 38% and 37% of the total time watching TV/videos and playing mobile phones, respectively. High school students spend the longest time using mobile phones(49%) of the total time, followed by watching TV/videos(26%). With the increasing of grade, screen time became longer, and screen time qualified rate dropped. Moreover, the most used electronic screens were mobile phones and TV/videos.

This investigation evaluated the Growth Psychoeducation Intervention (GPI) designed to increase primary school students’ covitality, a construct describing the beneficial combinatorial effects of positive psychological skills and mindsets. Students with higher covitality levels have stronger relationships with their teachers and classmates, and behave in more positive ways. This GPI intervention study employed a pretest-posttest-follow quasi-experimental design to evaluate a culturally adapted group counseling intervention designed to foster Chinese senior primary school students’ (n = 189, ages 9–12 years) covitality levels. The hypothesis was that covitality increases would positively correlate with school belonging and life satisfaction and less frequent bullying victimization. The Social Emotional Health Survey-Primary (SEHS-P) assessed the effectiveness of the GPI eight-week program to promote mental health and decrease bullying. GPI demonstrated effectiveness by improving students’ covitality and school belonging and reducing bullying victimization.

This study examined the effect of self-support on loneliness, the mediation effect of school belonging, and the moderation effect of self-esteem using a sample comprising 1,126 Chinese mainland primary school students, 621 are boys and 505 are girls, and their mean age was 10.51 years (SD = 1.63, range 8–13). Participants completed questionnaires regarding self-support, loneliness, school belonging and self-esteem. In the model hypothesis, self-support is an independent variable, loneliness is an outcome variable, school belonging is a mediating variable, and self-esteem is a regulatory variable. After controlling the demographic variables, the data were analyzed, and the results showed that: (1) self-support had a significantly negative predictive effect on loneliness; (2) the relation between self-support and loneliness was mediated by school belonging; and (3) the relation between school belonging and loneliness was moderated by self-esteem, supporting the moderated mediation model. Moderated mediation analysis further indicated that the mediated path make loneliness weaker for pupils with higher levels of self-esteem. These results revealed the formation mechanism of loneliness in primary school students and have certain enlightenment significance for the intervention of loneliness in primary school students. These results revealed the formation mechanism of loneliness among primary school students and have significant implications for interventions against loneliness in the primary school context.

Although there are some researches conducted about students’ conceptions of technology, little research has been conducted to reveal the primary school students’ conceptions concerning technology in China. This research investigated Chinese primary school students’ (aged 9–12) conceptions of technology as regards their understanding of (a) the concept of technology, (b) the impact of technology on human life and nature, and (c) the relationship between technology and science. Phenomenography as the methodological framework was adopted for this study. A total of 63 primary school students were chosen as participants in the study to probe their conceptions about technology through picture/photo eliciting activities, and semi-structured, personal interviews in a website video format. It is found that the primary school students defined technology from diverse perspectives, including the dimensions of its attributes, production, operation and use, function, with most of them regarding technology as a double-edged sword. It is also found that they lack a comprehensive and rational understanding of the concept of technology and cannot understand the relationship between science and technology properly. This study contributes better to understanding primary school students’ conceptions about technology in mainland China and beyond, thus providing an empirical basis for improving technology education policy, curriculum, instruction, and assessment in the future for China and other countries.

BackgroundThe internet has become an important resource for the public to obtain health information. Therefore, the ability to obtain and use such resources has become important for health literacy. This study aimed to establish a prediction model of Chinese students’ electronic health literacy (EHL) to guide government policymaking and parental interventions, identify the predictors of EHL in Chinese students using random forests, and establish a corresponding prediction model to help policymakers and parents determine whether primary and secondary school students have high EHL.MethodsThis is a cross-sectional study. From June to August 2021, a cluster sample survey was conducted with 1,300 students from seven primary and secondary schools in Shaanxi Province, China. We evaluated 1,235 primary and secondary school students using the e-health literacy scale. The data were divided into training and testing datasets in a 70:30 ratio for further analysis using random forest. The predictive accuracy of the score was measured using the area under the receiver operating characteristic curve. We also used decision curve analysis to determine the usefulness of the prediction model by quantifying the net benefits at different threshold probabilities in the validation dataset. ResultsWe found that 33.6% of students had high EHL. The univariate analysis showed that age (P < 0.001), grade (P < 0.001), employment status (P < 0.001), household location (P < 0.001), parental phubbing behavior (P < 0.001), and general self-efficacy (P < 0.001) were significantly associated with EHL. A random forest classification model was developed with the training dataset (872 students), and seven variables were confirmed as important: age, grade, employment status, father education level, game time, parental phubbing behavior, and general self-efficacy. The validation of the model showed good discrimination, with an area under the curve of 0.975 in the training dataset and 0.738 in the testing dataset. The model was translated into an online risk calculator, which is freely available (https://xietao.shinyapps.io/DynNomapp/).ConclusionsIn this study, an intuitive tool to predict the EHL of Chinese primary and secondary school students was developed and validated.

This study investigated the internal mechanism of the relationship between primary school students’ peer relationships and their performance in the Chinese language and literature. We constructed a chain mediation model, focused on the mediation effects of parental involvement and the sense of autonomy, on the correlation between peer relationships and performance in Chinese language scores. A questionnaire survey was conducted among 1,503 students in grades 4–6, and their parents, in three cities in Jiangsu Province. The result indicated the following: (1) there was a significant positive correlation between primary school students’ peer relationships, parental involvement, sense of autonomy, and the level of Chinese language scores; (2) parental involvement and the sense of autonomy, respectively, mediate the relationship between peer relationships and Chinese language scores; (3) primary school students’ parental involvement and sense of autonomy play a chain-like mediating role in the relationship between their peer relationships and Chinese language scores. The research results provide a reference for exploring the educational strategies of primary school students’ Chinese literacy.

The development of a Digital Intelligence Quotient (DQ) scale for primary school students is the basis for research on the DQ of primary school students, which helps to scientifically diagnose the level and the current average DQ among Chinese primary school students. This study developed and validated a scale applicable to the assessment of DQ in Chinese primary school students where, the initial scale was first constructed; Then 1109 valid datasets were collected through purposive sampling and divided into Sample A and Sample B; Sample A was subjected to exploratory factor analysis and Sample B was tested by confirmatory factor analysis; The final validated scale consists of 22 items in 7 dimensions: digital identity, digital use, digital safety, digital security, digital emotional intelligence, digital literacy and digital rights. The scale has high reliability and validity and thus can be used as a reliable instrument for assessing DQ in Chinese primary school students.

English is the compulsory subject from Primary Three in China since 2003. However, the Chinese curriculum in primary school highlights Chinese and Mathematics more than English. This causes Chinese primary school students' poor speaking English. Objectives of this paper is to explore the root causes of primary school English beginners' speaking problems. As a pilot study, samples are eight primary school students aged 7-11 at the BEST English Training Institution selected by the purposive sampling method. To identify the critical situation, Second Language Acquisition, Cone of learning, and Customer Knowledge Management are applied. The findings are 1) the root cause of teachers' teaching problems is passive teaching; and 2) Chinese students have difficulties in speaking English.

ObjectiveThe school-age children are in the stage of rapid growth and development, and balanced diet and rational nutrition is the basis for the normal development of children and even the health of their whole life. The study was designed to assess the nutritional literacy and health behaviors in Chinese primary school students.MethodsA total of 5582 Chinese primary school students participated in the study. Self-designed questionnaire was used to collect the information of nutritional literacy and health behaviors. The students were divided into four groups based on their scoring rate in response to the scores answering the nutritional literacy questions.ResultsThe overall scoring rate of answering the nutritional literacy questions was 0.89 for students in Grades 1–3 and 0.75 for those in Grades 4–6. Among students in Grades 1–3, the scoring rates of answering the questions related with dietary recommendations, food safety, characteristics of food, dietary habits, and nutrition and disease, were 0.82, 0.89, 0.95, 0.95, and 0.92, respectively. For the students in Grades 4–6, the scoring rates were 0.53, 0.85, 0.77, 0.81, and 0.89, respectively. Compared with G1 group, more students in the G4 group have the habit of having breakfast, and have higher frequency of consuming cereals, vegetables, fruits, meat, whole grain, and eggs, lower frequency of drinking sugary-sweetened beverages. And students in Grades 4–6 of G4 consumed less sea food. A positive correlation between the overall scoring rate and the frequencies of consuming breakfast, cereals, vegetables, fruits, meat, whole grain, and eggs was observed. Conversely, a negatively correlation between the overall scoring rate and the frequency of the sugar-sweetened beverages.ConclusionEmphasizing dietary recommendations in nutrition education for primary school students is necessary. Furthermore, higher nutritional literacy among Chinese primary school students is associated with greater dietary diversity and high frequency of breakfast consumption.

Inhibiting intuitive rules in a geometry comparison task: Do age level and math achievement matter?

Parental involvement may influence the subjective well-being of primary school students, but the specific mechanisms remain unclear. This study explores the mechanisms between parental involvement and primary school students' subjective well-being. The current study investigated 340 fifth and sixth grade students and their parents from a primary school using the Parental Education Involvement Behavior Scale, the Well-Being Scale, the Sense of Security Scale, and the Learning Self-Regulation Scale. We found that (1) sense of security plays a complete mediating role between parental involvement and primary school students' subjective well-being; (2) autonomous motivation has a marginal mediating effect between parental involvement and subjective well-being of primary school students; and (3) sense of security and autonomous motivation play a chain mediating role between parents' educational involvement and primary school students' well-being. In conclusion, parental involvement appears to contribute to primary school children's subjective well-being, and this effect may be mediated individually and sequentially by the children's sense of security and autonomous motivation.

The lifestyles change of children and adolescents during the COVID-19 pandemic due to antipandemic measures can affect their sleep health. Existing studies have used convenient samples and focused on the initial months of the pandemic, leaving a knowledge gap on changes in young people's sleep patterns under the "new normal" under COVID-19. As part of a territory-wide epidemiological study in Hong Kong, this cross-sectional study recruited primary and secondary school students by stratified random sampling. Sleep parameters were collected using the structured diagnostic interview for sleep patterns and disorders. We investigated the pandemic's effects on sleep parameters by comparing data of participants recruited pre-COVID and those recruited during COVID using multivariate regression, adjusting for age, sex, household income, seasonality, and presence of mental disorders, and the moderators and mediators of the effects. Between September 1, 2019 and June 2, 2021, 791 primary and 442 secondary school students were recruited and analyzed. Primary school and secondary school participants assessed before COVID had a longer sleep latency on school days (95% confidence interval [CI] = 1.0-5.2 minutes, adjusted P-value = .010; and 95% CI= 3.9-13.0 minutes, adjusted P-value = .004, respectively) and nonschool days (95% CI = 1.7-7.2 minutes, adjusted P-value = .005; 95% CI = 3.4-13.7 minutes, adjusted P-value = .014, respectively). Low household income was a moderator for later bedtime (adjusted P-value = .032) and later sleep onset (adjusted P-value = .043) during nonschool days among secondary school students. Changes associated with COVID have a widespread and enduring effect on the sleep health of school-aged students in Hong Kong. Household income plays a role in adolescent sleep health resilience, and the impact of antiepidemic measures on the health gaps of the youth should be considered. Chau SWH, Hussain S, Chan SSM, etal. A comparison of sleep-wake patterns among school-age children and adolescents in Hong Kong before and during the COVID-19 pandemic. J Clin Sleep Med. 2023;19(4):749-757.

It is beneficial for teachers’ effective teaching to be aware of the characteristics of students’ learning strategies. This paper employed “Questionnaire of Primary School Students’ EFL Learning Strategies” of high reliability and validity and examined Chinese primary school students’ EFL learning strategies. 700 students participated in the investigation. Results indicated that the general situation with respect to participants’ EFL learning strategies was not optimistic. The most frequently used was cognitive strategy, followed by meta-cognitive strategy, and the least frequently used strategy was social/affective one. In addition, interaction between school, gender and grade was significant, the scores obtained were closely associated with individual school’s teaching level, and girls gained more scores than boys.

The Investigation of critical thinking disposition among Chinese primary and middle school students

Nowadays, it is widely acknowledged worldwide that music education is a beneficial activity for students’ cognitive, social, and emotional development (Ho, 2021). However, there is limited empirical evidence on how music education affects academic achievement in primary schools, especially in China. The aim of this literature review is to examine the existing research on the impact of music education on the academic achievement of primary school students in China, focusing on three aspects of music education: instrument-vocal training, music composition and music appreciation. The review synthesised the results of different research approaches and highlighted the importance of music education in enhancing Chinese primary school students’ motivation, creativity, and self-esteem, as well as in promoting cultural diversity and social harmony (Bao, 2020; Wang, 2021). Limitations of the current literature are then discussed and directions for future research are suggested, concluding that the main conclusion - that music education has a relatively positive impact on academic achievement in Chinese primary schools - requires more rigorous and comprehensive research to explore the underlying mechanisms and contextual factors that influence this relationship.
