在新冠疫情考验下,在线教学获得了积极发展的契机。在线教学中教师情感投入需要做到知情统一,共情移情,并为教师综合素养提供支撑。然而,不论从学界看,还是在现实环境中,亦或是在未来教学中,在线教学中教师情感劳动都面临着二元对立下的重知轻情、时空壁垒下的施效失调等巨大挑战。在线教学中教师情感教育的践行必须着眼教学情感目标设计,完善情感实施途径,注重情感的互通互融,并推进知情一体的教学评价方式。
In order to study the influence of inlet and outlet pressure difference and triangular buffer groove on the internal leakage of continuous rotary electro-hydraulic servo motor,the flow field model of motor with and without triangular groove is established
【摘 要】本文结合课堂教学实例，从听前活动、听中活动和听后活动三方面分析了影响听的教学的原因，并提出了相应的改进措施，以探索提高听的教学实效的策略。 【关键词】听的教学；媒介；指导；策略 由于学生的身心发展特点不同，对增量语言的认识、掌握和习得程度也不尽相同。这就要求教师这位参与者要根据不同学生的不同反馈随时调整教学设计，引导学生合理的梳理所听语言材料，并进行必要的听的学习策略指导，将掌握的语
