The conventional Hall effect is linearly proportional to the field component or magnetization component perpendicular to a film. Despite the increasing theoretical proposals on the Hall effect to the in-plane field or magnetization in various special systems induced by the Berry curvature, such an unconventional Hall effect has only been experimentally reported in Weyl semimetals and in a heterodimensional superlattice. Here, we report an unambiguous experimental observation of the antisymmetric planar Hall effect(APHE) with respect to the in-plane magnetic field in centrosymmetric rutile RuO_(2) and IrO_(2) single-crystal films. The measured Hall resistivity is found to be linearly proportional to the component of the applied in-plane magnetic field along a particular crystal axis and to be independent of the current direction or temperature. Both the experimental observations and theoretical calculations confirm that the APHE in rutile oxide films is induced by the Lorentz force. Our findings can be generalized to ferromagnetic materials for the discovery of anomalous Hall effects and quantum anomalous Hall effects induced by in-plane magnetization. In addition to significantly expanding knowledge of the Hall effect, this work opens the door to explore new members in the Hall effect family.

农村小学课后服务的实施不仅是国家的重大战略部署,也是社会对课后服务的迫切需要,更是农村基础教育高质量发展的内生诉求。双减政策颁布以来,农村小学课后服务虽取得一定成效,但因师资、经费、资源等相较于城市仍存在一定差距,加之对农村小学课后服务的关注度不够,农村小学在课后服务实施中或多或少存在配套政策供给有待明晰、多方主体权责界线模糊,经费拨付保障尚不健全、课后服务设施场地受限,师资队伍结构质量失衡、激励纾解机制尚不完善,监管评价机制尚不明晰、数字资源应用效率不高等问题。为此,顶层设计方面,需完善配套政策法规供给,形成多方主体联动机制;保障机制方面,应强化基础设施建设应用,建立经费统筹保障机制;师资建设方面,可深化教师队伍线上协同,构建师资发展长效模式;监管评价方面,要优化实施监管评价机制,依托数字赋能资源共享。

目前教育生态学说受到广泛关注。类似自然环境中的生态危机,教育也面临挑战。教育起源于劳动需要,带有功利主义色彩,并经历了从外在目的到“无目的”的变迁。存在主义视野中的教育生态平衡呼唤着对教师权威角色的辩证态度,审视师生心理契约的自由联结,激发教师浪漫精神,这是救赎教育生态危机的关键。

人性论探讨的是人的本质和特征,不同的哲学和心理学流派对此有着各自不同的理解。中国哲学中的人性论和马克思主义哲学关于人性的论述,是我国教育事业发展的理论基石。蔡元培先生的“尚自然,展个性”的教育思想,强调个体应追求自然本质,发展和展现个性,与人性论的教育思想相契合。在人性论视角下,蔡元培先生的“尚自然,展个性”教育思想对高校学生发展提供了以下三点教育启示:一是要顺其自然,遵循教育规律;二是要统筹协调,重视社会性和个性和谐发展;三是要以人为本,关注精神成长。
