This editorial paper presents 11 papers related to the special issue proposed by UNICEF on the Education Response to COVID-19. The COVID-19 pandemic provoked an education emergency of unprecedented scale. At its onset in February 2020, school closures were announced in the worst-hit countries. At the peak of the crisis, 90 per cent of learners worldwide had had their education disrupted. Some learners, especially those from the most marginalised population groups, were put at risk of permanent dropout, provoking long-term and significant negative effects on children’s life-long wellbeing and the socio-economic development of their communities and countries. This special issue, which received contributions from UNICEF staff and various researchers, focuses on the impact of school closures, the effectiveness of remote learning solutions, equity implications, the mitigation of learning loss and notions around re-opening better. Different research perspectives and evidence is gathered to help strengthen policy considerations and future planning. The conclusion emphasizes building on the innovative solutions generated by the response to the crisis to make education systems more resilient, whilst also reinforcing the focus on equity and inclusion so that pre-existing disparities are not exacerbated in the future.  相似文献

Consensual sexual harassment on Iranian campuses is getting prevalent; however, this phenomenon has not been examined yet. This study contributed to the area and investigated the sexual relationships shapes, the behaviour of Iranian faculty members and female college students, and the consequences of sexual harassment for the victims, even in its consensual form. Hence, the phenomenological qualitative method was applied to explore the experiences of 10 female graduate students. The data were collected through online in-depth interviews due to the COVID-19 pandemic. In line with the theoretical framework proposed by Terpstra and Baker (1986), the interpretive phenomenological analysis revealed three themes of Onset, Sexual treatment, and After effects. According to the results, the basic needs of the females and the professors’ leering seduced the females to enter into sexual relationships. The results also reflected the academic and psychological consequences of sexual harassment on the victims’ future. The findings have some implications for higher education policymakers, university chancellors, and governmental officials.  相似文献

As one of the potential contextual factors for creativity development, children’s museum has been introduced to China from the western world in recent years, with the aim to offer a new informal educational environment to enhance children’s creativity. Based on experimental data for two groups of 4-year-old preschoolers (218 for the family mode and 202 for the preschool mode) from Beijing with an appropriately one-year long intervention (September 2017 to July 2018), this study examines the effect of regular visits to a children’s museum and other education environmental factors on young children’s creativity measured by Torrance’s Thinking Creatively in Action and Movement (TCAM) test. Results indicate that in terms of family visit, compared to the control group, the intervention that offers 18 times free tickets to visit a children’s museum significantly improved the experiment group’s originality (a sub-measure of creativity) by an additional 34.51 %. A beneficial effect of this intervention was also found in improving children’s fluency from the sample of preschool group visit (46.80 %). In addition, family education environment factors such as public preschool attendance, frequency of visits to science museums, and the degree of parents’ latitude were also found to positively affect creativity. Children’s personal features such as sex and geographic location of the family are also found to be related with children’s creativity.  相似文献

Forty anatomy articles were sampled from English Wikipedia and assessed quantitatively and qualitatively. Quantitatively, each article’s edit history was analyzed by Wikipedia X-tools, references and media were counted manually, and two readability indices were used to evaluate article readability. This analysis revealed that each article was updated 8.3 ± 6.8 times per month, and referenced with 33.5 ± 24.3 sources, such as journal articles and textbooks. Each article contained on average 14.0 ± 7.6 media items. The readability indices including: (1) Flesch–Kincaid Grade Level Readability Test and (2) Flesch Reading Ease Readability Formula demonstrated that the articles had low readability and were more appropriate for college students and above. Qualitatively, the sampled articles were evaluated by experts using a modified DISCERN survey. According to the modified DISCERN, 13 articles (32.5%), 24 articles (60%), 3 articles (7.5%), were rated as “good,” “moderate,” and “poor,” respectively. There were positive correlations between the DISCERN score and the number of edits (r = 0.537), number of editors (r = 0.560), and article length (r = 0.536). Strengths reported by the panel included completeness and coverage in 11 articles (27.5%), anatomical details in 10 articles (25%), and clinical details in 5 articles (12.5%). The panel also noted areas which could be improved, such as providing missing information in 28 articles (70%), inaccuracies in 10 articles (25%), and lack or poor use of images in 17 articles (42.5%). In conclusion, this study revealed that many Wikipedia anatomy articles were difficult to read. Each article’s quality was dependent on edit frequency and article length. Learners and students should be cautious when using Wikipedia articles for anatomy education due to these limitations.  相似文献

目的:分析舞龙运动对女大学生血常规及内皮祖细胞含量的影响。方法:选取2017级舞龙队女大学生10人为训练组,2017级普通女大学生10人作为对照组。舞龙队女大学生备战比赛进行连续4周,每周3次,每次90min的赛前集训,普通女大学生除日常活动外,没有额外进行任何其他运动队的集训。集训结束后,在受试者都处于空腹状态下对两组受试者进行静脉采血并进行血常规、早期内皮祖细胞和晚期内皮祖细胞的检测。所得数据进行统计学分析。结果:参加舞龙集训的女大学生的血常规指标与普通女大学生的血常规指标无显著差异,早期EPCs和晚期EPCs无显著性差异,但在数值上显示出不同的趋势。结论:参加舞龙集训的女大学生身体处于健康状态。参加舞龙集训有可能增强运动员血管的自我修复能力。  相似文献

Education Preparation Programs (EPPs) are increasingly pressured to demonstrate alignment between program supports and candidates’ outcomes. Using mixed methods, we studied the Early Field Immersion School (EFIS), an effort to improve candidates’ early field experiences. Participants included 171 candidates enrolled in a graduate certificate program and 11 university-based faculty. EFIS candidates spent increased time in early field experiences, yet EFIS was not associated with candidates’ performance at program exit. Although we found that while candidates and faculty alike valued EFIS supports, participation was negatively associated with perceptions of preparedness. We discuss these discrepancies and offer suggestions for ongoing research.  相似文献

ABSTRACT

This study seeks to examine the influence of the cultural elements on international students’ country choice. It also examines whether individual values moderate the influence of cultural elements on the country choice of international students. Drawing upon a sample size of 223, the data was analysed using structural equation modelling technique. Among the five cultural elements, education, language and social institutions were found to have a positive significant influence on the international student’s country choice. When moderated by individual values education was found to be the only key significant value to international students when selecting a country to further their education. The cultural elements should be given much attention by marketers, government and managers of academic institutions. An improvement in the standards of education in developing countries would attract more students from developed countries.  相似文献
