As a national matter, the construction of teaching materials has always been a focus of the government and academia, but the construction from the perspective of aesthetic education has not yet received the due attention from all walks of life. Teaching materials construction is a complex project, and an effective method is to construct teaching materials from the perspective of aesthetic education, serving as an important guarantee to achieve the goal of educating people and nurturing talents. The construction activities like compiling, reviewing and utilising teaching materials should abide by aesthetics and beauty creation awareness, follow the laws of students’ psychological development, individual differences and sustainable development, with the value of promoting students’ all-round development. It is becoming a trend in the new era to promote the integration of aesthetic education in primary school, middle school and college teaching materials, the construction of aesthetic education teams, and the development of courses of the aesthetic education of teaching materials.

大概念和单元都是落实立德树人、促进学生核心素养发展的重要载体,大概念与单元整体教学的整合是二者内在逻辑关系的共同需求.基于大概念进行单元整体教学,有利于核心素养与育人目标真正落地课堂.进一步厘清了大概念内涵,分析了大概念与单元整体教学之间的逻辑关联,概括了大概念的提炼路径,并结合课例阐述了基于大概念的单元整体教学实施路径,旨在提升单元整体教学的育人效果.

推进课程思政建设有助于落实立德树人根本任务,但在基础英语教育领域,涉及课程思政的理论和实践研究并不多,初中英语教师对课程思政也不熟悉,难以将其落实到教学中.因此,初中英语教师应以一系列教育理论为基础,在课程思政视域下开展单元整体教学,挖掘课程思政价值,建构单元大概念体系;围绕课程思政价值,设计单元学习目标与评估证据;聚焦课程思政价值,规划课时学习活动.

作业改革始终是"减负"的核心要点.适量的作业是有利于学生发展的,不布置作业不是"双减"政策的初衷.以大数据为抓手进行作业管理是有效推进作业改革的保障,以"育人"为导向提高作业设计的质量是作业改革取得成效的关键.

A novel anti-clotting biomaterial which was prepared from montmorillonite and silicone rubber through solution intercalated reaction was synthesized.The composite membrane was characterized by FT-IR,XRD and mechanical properties test.The hemolysis and adhesion of blood platelet tests were used to characterize the blood compatibility of composite membrane.The result shows that the composite membrane has good anticoagulant properties.

In this research,a novel anticoagulative biomaterial which was prepared from modified graphite oxide and silicone rubber through solution intercalated reaction was synthesized.The excellent properties of nanocomposites were characterized by FTIR,XRD,SEM,mechanical properties,hemolysis test and the adhesion of blood platelet test.The results show that the nanocomposites are improved both in mechanical properties and biocompatibility.This new biomaterial could be expected to find wide application in the medical treatment in future.

Na-montmorillonite (Na-MMT) was modified chlorhexidine acetate (CA) with using ion-exchange method, and the structures and property of CA/MMT were studied. The results of thermogravimetric analysis, X-ray diffraction and FTIR analysis show that CA are intercalated interlayer of montmorillonite, and the onset decomposition temperature of CA/MMT antibacterial composite is about 218°C. The antimicrobial experiment indicates that the CA/MMT antibacterial composite possess wonderful antimicrobial activity and the minimal inhibitory concentrations (MIC) are 6.25 and 50μg/ml against S.aureus and E.coli, respectively.

The binary of fatty acids/montmorillonite composite phase change material was prepared through solution intercalated reaction.The structures and properties of composite phase change material were characterized by using XRD,FT-IR,DSC,thermal energy storage and release test,performance stability test.The results showed that the binary of fatty acids were intercalated effectively into the nano-layers of montmorillonite and formed the stabilized composite system.The composite phase change material exhibited good properties of structure and thermal energy storage and release rates.In addition,after experienced 1000 times heating-cooling cycles test,the phase change temperature and latent heat of the composite phase change material had little change.The composite phase change material showed not only in performance stability,but also in the long-time thermal energy storage and release,which could be expected to find wide application in the energy-saving in future.

In our experiments,the natural clay sodium montmorillonite(MMT) has been organically modified via carboxyl methyl-chitosan/silver(CMC-Ag).Modified functional MMT was analyzed by FTIR,XRD and TG.The d-spacing of CMC-Ag/MMT has increased to 6.1982 nm.The antibacterial activity and antibacterial mechanism of this novel functional organic MMT to staphylococcus aurous(ATCC 25923),pseudomonas aeruginosin(ATCC27853),escherichia coli(ATCC 25922) and candida albicans(ATCC 10231) are also studied.

A novel anticoagulative biomaterial which was prepared from modified graphite oxide and silicone rubber through solution intercalated reaction was synthesized.The excellent properties of the new type nanocomposites,such as good mechanical strength and blood compatibility,have been characterized by XRD,mechanical properties,adhesion of blood platelet test and the heparin release rate test.The results demonstrate that the nanocomposites are improved not only in mechanical properties and biocompatibility,but also in the long-time blood compatibility,which could be expected to find wide application in the medical treatment in future.
