Postsecondary Students with LD/ADHD Facing a Sudden Shift to Online Learning during the COVID-19 Pandemic—Emotional Costs and Implications     

Maya Kalman-Halevi  Rony Tutian  Yehuda Peled 《Learning disabilities research & practice》2023,38(3):239-247

This study examined the emotional costs and well-being of postsecondary students with learning disabilities (LD) and attention deficit hyperactivity disorder (ADHD) who faced a sudden shift to emergency remote teaching (ERT) during the COVID-19 pandemic. The study was conducted with 237 postsecondary students in Israel from June to July 2020. With regard to online learning, the LD/ADHD subjects reported significantly higher levels of stress, anxiety, and depression and lower well-being than their neurotypical counterparts. However, no significant differences were found in emotional costs and well-being when the same students had experienced online learning prior to the pandemic. These findings have practical implications for policymakers in academia with regard to the emotional toll of online learning among students with LD/ADHD and their specific needs when facing ERT during the COVID-19 pandemic as well as the contribution of previous online learning when facing ERT.  相似文献   

折出一间房子

纸这种柔软洁净的材料,通过人类的双手,在游戏一般的过程中能带来无限种可能的形式。小时候看着大人手中如同变魔术一般出现的纸船、纸飞机、纸衣服慢慢成为遥远而模糊的记忆。相比层出不穷用纸说事儿的那些纸雕塑、纸房子,真有种小巫见大巫的感觉。关键是,这种身怀柔术绝技的材料,还能循环利用,操作起来简便易行,更关键的是,各位满心点子的高手们以纸为师,用各种灵感、材  相似文献   

第三代战斗机用大推力涡扇发动机巡礼（三）：昔日雄风今犹在——AЛ-31Ф系列发动机     

Maya 《航空档案》2008,(3):36-45

上世纪70年代初,苏联针对美国普惠的F100高性能发动机,决定由留里卡设计局负责研制一款性能相近的战斗机发动机,项目代号99（Изделие 99）、正式的型号名称为AЛ-31Ф。1974年8月装配完成了第一台AЛ-31Ф,然而随后的台架试车结果却令人失望,性能并没有达标,发动机超重的情况也比较严重,达1600kg,推重比指标和F100相去甚远。超重的主因是发动机级数过多：  相似文献

How autonomy support and ethical value alignment influences attitudes towards diversity in English police     

Maya Al-Khouja  Les Graham  Netta Weinstein  Yuyan Zheng 《Journal of moral education》2020,49(3):365-380

ABSTRACT

Antagonism towards diversity, an attitude reflecting low egalitarian ethical values, has been a topic within policing that has received increasing attention in the last decade. Using two-wave data and applying self-determination theory, we investigated how autonomy support versus autonomy frustration, ways of being motivated either through encouraging one’s sense of volition, or otherwise, coercing and imposing pressures, can improve diversity attitudes through its relation with ethical values. Study 1 (n= 398 police officers and staff) found that autonomy-supportive communications fostered ethical values, and hence was negatively related to diversity antagonism. Study 2 (n= 859 police officers and staff) indicated that motivation to overcome prejudice mediates the relationship between ethical values and diversity antagonism. Perceptions of workplace culture as lacking in autonomy support acted as a boundary condition for the ethical values and diversity antagonism relationship; no relationship was present when autonomy support was low.  相似文献

Value Profiles During Middle Childhood: Developmental Processes and Social Behavior     

Ella Daniel  Maya Benish-Weisman  Joanne N. Sneddon  Julie A. Lee 《Child development》2020,91(5):1615-1630

Little is known about how children's value priorities develop over time. This study identifies children's value priority profiles and follows their development during middle childhood. Australian children (N = 609; ages 5–12 at Time 1) reported their values over 2 years. Latent Transition Analysis indicated four profiles: Social-Focus, Self-Focus, Growth-Focus and Undifferentiated. Within person development was characterized by profile stability or transfer to the Social-Focus profile. Younger children were more likely to have an Undifferentiated profile (or Self-Focus among boys) than older ones. Girls were more likely to have a Social-Focus profile or transfer to it, and less likely to have a Self- or Growth-Focus profile than boys. Social-Focus profile membership over time predicted more prosocial and less aggressive behavior.  相似文献   

跨文化交际中的言语合作原则和礼貌原则     

吴力群 《中国科教创新导刊》2009,(11):79-80

本论文以中美两国为倒,指出由于在以下四个方面存在很大的不同：意识形态,面子体秉,话语形式和传统文化,因此人们在跨文化言语交际中所遵循的合作原则和礼貌原则的佣重点不同,这也就导致误解与不快,因此,在跨文化交际中,不仅要学习其他国家的文化特征,而且更应尊重其他国家的文化,这样跨文化交际才能持续和顺利地发展。  相似文献
