“教育数字化”是当前教育改革和实践的热点,技能本位的学习范式是教育数字化转型的内生动力。从认识论的角度提出知识学习是技能习得的基础;从方法论的角度规划高职院校技能本位学习的实施路径;从目标、方式、行动、认证体系构建等五个维度构建职业院校技能型人才培养的新范式,提出了数字化时代技能本位的新内涵。实践中,在智慧教育环境下构建网络直播、情景教学、案例教学等多种双师型教学环境,为高职学生提供一种数字化支持的技能本位的双师实践教学的教学新生态。研究发现,该教学形态中学生能够积极参与课堂教学,能够有效地获取知识、习得技能,形成创新能力和自我发展能力。

幼儿教师的共情能力有助于教师对幼儿的倾听理解与有效支持,使幼儿获得发展适宜性教育,但当前缺乏职业适切性的测量工具。鉴于此,采用质性分析与量化验证结合的方法,首先通过文献搜集梳理与专家咨询分析幼儿教师共情能力的内涵、结构并撰写题项,然后进行两次施测共获得907名幼儿教师的问卷调查数据,统计分析后获得正式量表。研究结果表明,幼儿教师共情能力是一个多维概念,不仅是个体心理特质的反映,更是作为幼儿教师的职业能力体现。各维度及机制表现为:认知共情是先决条件,情绪共情是基础内核,共情性理解是关键桥梁,共情性反馈是终极目的。编制的量表包含4个维度17个题项,测量模型拟合度较好,量表具有良好的信度、聚合效度与区分效度。相较已有量表,此量表围绕师幼互动情景、紧扣幼儿教师职业特征,在幼儿教师群体中更为适用。

实习是医学生从学校向医院过渡的重要阶段,不管是操作技能的锻炼还是诊疗思维的培养,每个实习医师的素质成长都离不开带教医师的指导。作为当前较热门的辅助工具,文心一言等预训练语言模型对教学新业态的冲击已得到关注。虽然人工智能在文本生成、语言理解等方面有较大优势,但其引发的思维钝化及信任危机是不容忽视的问题。参与式教学法讲究“以学生为中心、师生共同参与”,一般从课前准备、过程学习、课后评价三个方面落实。将人工智能和参与式教学法有效融合,有助于引导学生从被动学习向主动学习转化,可弥补单一教学方法各自存在的缺陷,提高教学效果。

Two soils, one consisting of 1:1 clay minerals at pH 4.5 and the other containing 2:1 clay minerals at pH 7.0, were used to estimate the conversion of added NH+4 under different C/N ratios (glucose as the C source) and the addition of potassium. Under lower C/N ratios (0:1 and 5:1), a large part of the added NH4+ in the acid soil was held in the forms of either exchangeable or water soluble NH4+ for a relatively long time and under higher C/N ratio (50:1), a large amount of the added NH4+ was directly immobilized by microorganisms. In the second soil containing appreciable 2:1 type clay minerals a large part of the added NH+4 at first quickly entered the interlayer of the minerals under both lower and higher C/N ratios. In second condition, however, owing to microbial assimilation stimulated by glucose the newly fixed NH4+c ould be completely released in further incubation because of a large concentration gradient between external NH4+ and fixed NH4+ in the mineral interlayer caused by heterotrophic microorganisms, which imply the fixed NH4+ to be available to plants. The results also showed that if a large amount of K+ with carbon source together was added to soil, the higher K+ concentration of soil solution could impede the release of fixed NH4+ , even if there was a lot of carbon source.

免疫检查点抑制剂(Immune checkpoint inhibitors,ICIs)是一种新型的免疫治疗方法,主要针对免疫细胞上的PD-1及其配体PD-L1、CTLA-4等免疫检查点分子,解除肿瘤细胞对免疫系统的抑制,增强机体的抗肿瘤免疫反应。然而,临床单独使用ICIs的应答率较低,且存在局限性。中医药治疗因其毒性小、疗效显著和组方灵活等特点,在癌症治疗中有着重要作用。研究表明,中药能够通过直接抑制PD-1/PD-L1轴、调节免疫细胞功能、免疫相关细胞因子和肿瘤相关通路等途径,改善肿瘤微环境,提高免疫治疗的敏感性。本文综述了中医药与ICIs联合使用的研究进展,探讨中药如何与ICIs协同作用,提高其抗肿瘤疗效。
