高职幼教专业语文教学模块构建

根据幼教专业的特性,其语文教学应侧重于“说”和“听”两部分,更重视口头语言的交流性,以及交流的生动性和有效性,更侧重于学生将来毕业时的学以致用,实现尽快适应理想幼儿教师角色的目标。本文结合自身教学实践,细化了幼教专业语文教学的目标,以幼教的职业期待为指导,构建了幼教专业语文教学的具体模块：1．“古诗词音乐表演”模块;2．“生动演讲者”模块;3“话剧表演”模块;4．“科普主题墙”模块。     

Experiences in education innovation: developing tools in support of active learning

The paper focuses on educational projects developed in the ETSII (Escuela Técnica Superior de Ingenieros Industriales) of the Polytechnic University of Madrid during the past few years. These projects were developed as new tools for enhancing the active role of students, for improving practical teaching, especially by means of virtual laboratories and different sets of problems and exercises, and for promoting self-learning. The paper analyses the use of ICT in teaching, with the case of a developed e-learning platform as a tracking system for subjects. The paper concludes by discussing the new educational trends in the Centre, devoted to develop an active role of students by activities such as peer mentoring and laboratory monitors programs, and competitions for achieving multidisciplinary engineering challenges.     

Information literacy instruction in four Vietnamese university libraries

This case study explored the perceptions of academic stakeholders about the development and delivery of information literacy (IL) programs in four universities, and identified elements necessary to establishing IL credit courses in Vietnamese higher education. The following research questions framed this study: 1) How do library administrators, instruction librarians, and faculty perceive the current implementation of information literacy instruction (ILI) programs for undergraduates studies in universities libraries in Vietnam? 2) What are the challenges to including IL as a credit course in the curriculum as perceived by library administrators, instruction librarians, and faculty? Respondents were purposefully recruited from four universities, including library administrators, instruction librarians, and faculty. Three online surveys were distributed to 537 individuals through Survey Monkey with 149 replies and a final receipt of 133 completed surveys. Interview and focus group data collection included 23 face-to-face interviews and nine focus groups. Findings showed IL is considered the domain of librarians and has not influenced Vietnamese campus culture. IL activities at four university libraries take the form of lectures, workshops, and basic IL skills modules. Few ILI activities are subject discipline-related. Respondents reported challenges to an ILI credit course revolve around the lasting impact of teacher-centered instruction and rote learning, misperceptions about the effect of IL on student learning outcomes, degree of support of IL by academic stakeholders, degree of faculty–librarian collaboration, and scarcity of resources. Recommendations are given for academic librarians in Vietnam implementing ILI programs and considering developing IL credit courses.

基于线性自抗扰控制的船舶航迹积分滑模控制器

为解决欠驱动船舶航迹直线和曲线跟踪控制问题,选取能解决航向不稳定等非线性问题的Bech模型,借助双曲正切函数,构造期望艏向方程,将航迹控制问题转化为航向控制问题。设计3阶跟踪微分器,对期望艏向及其微分信号进行精确提取。采用变结构积分滑模面函数设计非线性误差反馈控制律,加快系统收敛速度,提出基于线性自抗扰控制(Linear Active Disturbance Rejection Control,LADRC)的船舶航迹积分滑模控制器。该控制器的线性扩张状态观测器对系统内外总扰动进行在线估计与实时补偿;引入Hurwitz多项式,减少需整定的参数。仿真结果表明,航迹收敛快速准确,无超调,对外界干扰具有较强的鲁棒性。控制器参数具有一定的普适性,故其适用范围广。

导出了HPF的通带截止频率fp与特征频率f0的关系式,并通过对比找到了HPF与LPF的又一对偶关系──通带截止频率的对偶关系,从而解决了文献[1]中未明确指出的问题。     

ActiveX组件技术及其在Web中的应用

与传统软件开发技术相比,组件技术有其独特的优势。本文首先描述了ActiveX组件技术的概念及其特点,然后举例说明了如何在Delphi中开发ActiveX组件以及如何在ASP中调用组件。     

一种约束条件下有源电力滤波器的优化控制算法

本文在考虑满足不同的性能指标或某种实际要求时的基础上,提出了一种基于优化理论的有源电力滤波器的控制算法。该算法针对满足一定约束要求下来设计有源滤波器（APF：Active Power Filter）补偿性能,其补偿电流在a-b-c坐标系内确定,无需坐标变换．APF控制电路的实现比起传统方法相对简单,并通过仿真实验证明此算法有很好的滤波效果。     

教师在阅读教学中积极引导的方法和作用

英语阅读在学生的英语学习中的作用是无法忽视的。教师积极引导的方法是学生做好英语阅读的关键,教师在学生的阅读理解中积极的引导,一方面能够提高学生的阅读理解能力,另一方面,通过教师的积极探索、分析和研究,也将不断地提高教师的英语阅读教学水平,从而进一步提高引导学生学习英语阅读的能力.形成一个系统的良性循环。     

What’s in a Name: Defining Reference/Introducing Ourselves

ABSTRACT

Reference is the word we use for the actions that librarians engage in to answer questions from the public. The art and practice of reference involves many actions that likely can only be understand through engagement. Students in a graduate basic reference class engage in active learning to introduce themselves to their classmates and to understand how to define what reference is. Both activities involve placing words in context.
