Weighing Fog: Modeling on Day 1 of Differential Equations

Abstract

The first day of many mathematics classes is filled with the formalities of the syllabus and a lecture introduction to the course content. Here, an alternative is presented where modeling is placed as the centerpiece to orient students to the work of differential equations; namely, to capture as beautifully and compactly as possible through the process of inquiry, conjecture, and experimentation, the deep and interesting aspects of modeling the physical world. A demonstration of the sublimation of dry ice in water serves as the nucleus of the lesson.

梧州-肇庆试验区地下水在线远程监测系统设计

针对珠江-西江经济带,梧州-肇庆流域的水域地质环境及地下水监测野外工作现状,研制一套环境适应性强的地下水动态在线监测系统。系统主要由监测传感器装置、远程数据传输装置及终端平台组成。地下水监测系统中的供电部分采用太阳能发电方式,解决了偏远地区取电困难的问题,实现自动化、智能化供电。监测数据采用GPRS传输方式,将采集到的数据传到监测平台。野外试验表明系统运行状况良好,实现了自动化采集及远程传输,提高了工作效率。     

高校数据科学教育生态系统建构——以美国普渡大学为例

作为智能化社会的学科基础要素,大数据正在驱动着高等教育系统的范式变革。美国普渡大学一体化数据科学首倡计划发起的跨学科学术组织变革,强调以跨学科学位项目与学科交叉课程、学科会聚研究计划与研究团队、服务性学习数据社区与主题工作坊、产教融合的数据科学校企合作模式构建高校数据科学教育生态系统。值此加强新时代教育科学研究的战略契机,以"数据+"引导多学科会聚和教育模式创新,打造面向真实世界的数据科学实践社区,建设校企协同产教融合共同体,加快培育大学生数据思维和校园数据文化,将有助于高等教育治理体系改革和治理能力现代化的实现。     

Dynamic reciprocal relations of achievement goals with daily experiences of academic success and failure: An ambulatory assessment study

Achievement goals have been linked to achievement in various educational settings. The present work explored day-to-day variations in achievement goals (mastery, performance-approach, performance-avoidance) and their associations with daily experiences of academic success and failure. Ambulatory assessment data from 108 students in Grade 5 were collected, with daily assessments of achievement goals in the morning and end-of-day reports of academic success and failure. Dynamic structural equation models revealed reciprocal within-person effects between mastery goals and academic success. Academic success was further associated with higher mastery and performance-approach goals in the next morning. Academic failure was linked to both performance goals, though this association was not robust in all sensitivity analyses. Higher average daily academic success and lower average academic failure were linked to better academic achievement one year later. Findings suggest meaningful within-person dynamics among goals and daily academic success and failure.

Refreshing File Aggregate of Distributed Data Warehouse in Sets of Electric Apparatus

Integrating heterogeneous data sources is a precondition to share data for enterprises. Highly-efficient data updating can both save system expenses, and offer real-time data. It is one of the hot issues to modify data rapidly in the pre-processing area of the data warehouse. An extract transform loading design is proposed based on a new data algorithm called Diff-Match, which is developed by utilizing mode matching and data-filtering technology. It can accelerate data renewal, filter the heterogeneous data, and seek out different sets of data. Its efficiency has been proved by its successful application in an enterprise of electric apparatus groups.     

中本贯通教育内部质量保障机制的构建

中本贯通指职业教育中中专教育、大学专科教育到本科教育之间的贯通。它是高等职业教育的一项重要的改革措施。在这项工作中,教育内部质量保障机制具有主体多元化、培养周期长、关键环节多等特点,构建此机制对提升中本贯通人才培养质量具有重要意义,而目前此类研究较为缺乏。通过分析上海某高校近年来的探索经验,提出以整体设计、反向设计和多维设计的原则构建统一主体的民主决策机制、全过程质量监控机制和教学质量预警机制等内部质量保障机制,为提升中本贯通教育培养质量和中高职贯通、高本贯通等各类贯通教育试点改革提供参考。
