Experiment of Adopting the Learner Blog in CALL-based Practical English Writing Course

The learner blog is adopted in the instruction of CALL-based Practical English Writing course for A-level non-Eng lish major sophomores in our school in the spring this year.After examining how the program is implemented in detail,sugges tions are provided for future instructors in this related program.To ensure the program a good start,it is advisable for instructors to set aside a certain time to help each student to create a blog account in the beginning.Besides,it is requisite to provide stu dents with blogs titles with elaborate design and with the evaluation and further comment of the blog in the course of face-toface communication.Using of blogs in CALL-based Practical English Course is helpful in improving students'writing quality,in gearing up self-introspection for participants,in creating cooperative learning community,in fostering autonomous learning and cooperative learning,in building up communicative channels between students and instructors and among students themselves.

Compressive strength and frost heave resistance of different types of semi-rigid base materials after freeze-thaw cycles

Freeze-thaw damage is the most common disease of semi-rigid bases in cold regions, which may greatly affect the dura- bility of roadways. In this study, the compressive strength and frost resistance of four different types of semi-rigid bases （lime-fly ash-stabilized sand, cement-stabilized sand, lime-fly ash-stabilized gravel, and cement-stabilized gravel） are assessed by varying the materials content. Based on freeze-thaw and compressive strength tests, this paper presents the performance of the different materials, each having different physical properties, and the optimal amounts of materials contents are proposed.

Study on Test Methods for Mechanical Properties of Semi-rigid Base Cores of In-service Pavements

Compressive strength and compressive resilience modulus are two important parameters to measure the mechanical properties of semi-rigid base.The test methods of semi-rigid base cores are different from those of the laboratory samples in terms of sample acquisition,sample selection and humidity requirements.Core-drilling location,size of core sample,smoothness and humidity conditions were analyzed.The test methods of compressive strength and compressive resilience modulus were proposed.The research results show that compressive strength of lime fly-ash stabilized gravels base has a tendency of increasing during a long period.The compressive resilience modulus increases significantly with compressive strength of semi-rigid base.The compressive resilience modulus generally is 3-4 times than the recommended range of asphalt pavement design specifications.The fluctuation range of compressive resilience modulus is obviously higher than the compressive strength.The compressive resilience modulus is more sensitive to the construction variability.The overall trend between the compressive resilience modulus and the back-calculation modulus is consistent.FWD(falling weight deflectometer)back-calculation modulus can reflect the stiffness and bearing capacity of asphalt pavement.

中小学课程思政一体化的价值意涵、现实境遇与实践向路

中小学课程思政一体化是新时代落实立德树人根本任务的重要举措。一体化的课程逻辑基于学生的身心发展规律和学科课程育人性质:“一”指向课程思政目标的统整,聚焦立德树人根本任务;“体”指向课程思政内容的融通,关涉“五育融合”的思政要素;“化”指向课程思政实施的衔接,契合“必备品格”的发展过程。课程思政一体化在中小学阶段面临课程思政目标的引领作用不强,课程思政内容的嵌入空间失衡,课程思政实施的融合方式单一,课程思政评价的体验过程窄化等困境。要想突破这些困境,需要在以下几个方面进行努力:以价值观教育为出发点,强化立德树人目标的课程思政引领作用;以五育融合为切入点,厘清知识与道德的课程思政育人限度;以品格塑造为联结点,融通认知与非认知的课程思政育人方式;以增值评价为着力点,兼顾结果与过程的课程思政育人价值。

基于PathSim的MOOCs知识概念推荐模型

大规模开放在线课程提供大规模开放式在线学习平台,为推进现代教育发挥关键作用。然而,减少用户学习盲区和改善用户体验方面的研究仍具有挑战性:交互数据稀疏;难以扩展到大型推荐任务上;用户需求不单由用户喜好决定,还受到不同教师、课程影响;以统一的方式对课程学习事件中不同类型实体及关系进行建模并不妥靠。基于此,引入相关性度量,依据全图结构信息计算各边权重,提出采用相关性度量算法PathSim进行邻域采样的知识概念推荐模型PathSimSage。各实体间相关性得分可在本地离线计算,将神经网络与传播过程分离,保证神经网络的堆叠层数和传播过程的独立性,大幅减少模型所需训练时间。在公开的MoocCube数据集上进行了综合实验,PathSimSage降低了不相关的信息甚至噪声的影响,解决随机游走采样所引发的高度节点偏差问题,并在一定程度上缓解了过平滑效应。
