This paper presents our ongoing efforts in developing mathematical models to make early predictions, even before the semester starts, of what score a student will earn in the final comprehensive exam of the engineering dynamics course. A total of 1,938 data records were collected from 323 undergraduates in four semesters. Employed were four different mathematical modeling techniques: multivariate linear regression, multilayer perceptron neural networks, radial basis function neural networks, and support vector machines. The results show that within the five predictor variables investigated in this study, there is no significant difference in the prediction accuracy of these four mathematical models.
本文介绍了我们在开发数学模型方面所做的持续努力,甚至在学期开始之前,就可以对学生在工程动力学课程的期末综合考试中获得的分数进行早期预测。在四个学期中,从323名本科生中收集了1938条数据记录。采用了四种不同的数学建模技术:多元线性回归、多层感知器神经网络、径向基函数神经网络和支持向量机。结果表明,在本研究研究的5个预测变量内,这4种数学模型的预测精度没有显著差异。

Work in progress: A constructivist didactic methodology for a humanoid robotics workshop 正在进行的工作:人形机器人研讨会的建构主义教学方法

This paper presents a constructivist methodology oriented to training Robotics in its wide sense, and its implementation in higher education. A humanoid robotics workshop is included as a part of the curriculum of `Industrial Robotics' in the Industrial Engineering. This workshop covers one third of the laboratory practices of this subject. A constructivist view for learning is adopted, whereby robotic technologies are not seen as mere tools, but rather as potential vehicles of new ways of thinking about teaching, learning and education at large. Students, in a constructivist learning environment, are invited to work on experiments and authentic problem-solving; with selective use of available resources according to their own interests, research and learning strategies. The authors, as trainers of this workshop, chose ROBONOVA humanoid robots, among other devices, which attempt to partner technology with ideas of constructivism. The materials used in the workshop offer building parts, sensors thus connecting a robot with the external environment and programming software with a simple graphical interface intended for the creation of robot behavioral movements. The idea is “learning by design”, which is central in the constructivist pedagogy introduced firstly by Resnick. In this workshop we corroborate this idea through the project-based learning approach in robotics. Learning tasks of the workshop are organized as projects (small and large) that encourage students to develop their own designs. Projects are either instructor led or completely arisen from students.
本文提出了一种面向广义机器人训练的建构主义方法,并将其应用于高等教育。人形机器人工作坊是工业工程“工业机器人”课程的一部分。本讲习班涵盖了本学科三分之一的实验室实践。采用了一种建构主义的学习观点,即机器人技术不被视为仅仅是工具,而是作为对教学、学习和教育的新思维方式的潜在载体。在建构主义的学习环境中,学生被邀请进行实验和真实的问题解决;根据自己的兴趣、研究和学习策略,有选择地利用现有资源。作为本次研讨会的培训师,作者在其他设备中选择了ROBONOVA类人机器人,这些设备试图将技术与建构主义思想结合起来。车间中使用的材料包括建筑部件、传感器,从而将机器人与外部环境连接起来,以及带有简单图形界面的编程软件,用于创建机器人的行为动作。这个想法是“通过设计学习”,这是雷斯尼克首先提出的建构主义教学法的核心。在本次研讨会中,我们通过机器人中基于项目的学习方法来证实这一想法。工作坊的学习任务被组织为项目(或大或小),鼓励学生发展自己的设计。项目要么由老师主导,要么完全由学生提出。

In our Operating Systems course we make available in advance the lecture slides and lab sessions material. The slides are built paying attention to present the key ideas and with embedded links to sites in the Web where the topic is covered in greater detail. We also provide the corresponding excerpts of selected textbooks. Following the download activity and paying attention on what our students are doing during the lectures, we are able to collect some data on notes usage. By carefully selecting some questions in the test we can distinguish which student used the material available in links and excerpts. In this paper we present some patterns of use of the lecture notes.

White privilege is an important concept when considering issues such as social justice, the internal “culture” of engineering education and systematic change in engineering education. However, it is not well understood by most engineering educators. This Special Session will help participants explore the idea of White Privilege within the context of engineering education. Through an interactive format, participants will learn some theory and develop some ideas for addressing White Privilege in engineering learning environments. The related idea of stereotype threat will also be discussed.
白人特权是考虑社会公正、工程教育内部“文化”以及工程教育系统变革等问题时的一个重要概念。然而,大多数工程教育工作者并没有很好地理解这一点。这个特别会议将帮助参与者在工程教育的背景下探索白人特权的概念。通过互动形式,参与者将学习一些理论和发展一些在工程学习环境中解决白人特权的想法。本文还将讨论刻板印象威胁的相关概念。

Indian universities broadly follow an entrance process for undergraduate engineering process in which physics, chemistry and mathematics based questions are asked. Either the individual scores or some combination of these scores is used to set the admission criterion for different engineering streams. However, it has not been analyzed whether this is a good predictor of undergraduate performance or not, especially in Indian context. The broad goal of this research is to understand the relationship between entrance criterion and undergraduate Computer Science/Information Technology performance. The analysis includes data collected from the students who appeared in the entrance exams and took admission in IIIT-Delhi in between 2008 to 2010. The scores obtained in entrance exams and cumulative grade point average earned during the first year of their studies are analyzed. Preliminary analysis suggests that for computer science undergraduate studies, mathematics or numerical understanding is an important aspect. Further, logic and aptitude based tests are better correlated in context of computer science education.
印度大学普遍遵循工程学本科的入学程序,其中包括物理、化学和数学方面的问题。单个分数或这些分数的某些组合用于设置不同工程流的录取标准。然而,还没有人分析这是否能很好地预测大学生的表现,尤其是在印度的情况下。本研究的总体目标是了解入学标准与计算机科学/信息技术本科生绩效之间的关系。该分析包括从2008年至2010年间参加印度理工学院德里分校入学考试和录取的学生收集的数据。对入学考试成绩和第一年的累计平均成绩进行分析。初步分析表明,对于计算机科学本科学习,数学或数值理解是一个重要方面。此外,逻辑和能力倾向测试在计算机科学教育的背景下更好地相关。

National calls have been made for the identification of preconceptions and misconceptions in science and engineering. Identifying misconceptions can provide a basis for improved research-based curriculum development and implementation. The recognition of false beliefs and flawed mental models of these concepts can also contribute to theories of conceptual change. The purpose of this research was to identify misconceptions related to open channel flow. During spring and fall of 2011, out of 91 students from two sections of `Water Resources Engineering' course, 50 students were interviewed, and 41 students were given a pre/post test. The goal of these open-ended interviews and pre/post-tests was to obtain detailed data on students understanding of open channel flow concepts. Results suggest students have misconceptions relating to the hydraulic and energy grade line (HGL/EGL), flow transitions, and flow profiles. Many students have the correct terms of the HGL and EGL but lack understanding of where the terms re on an open channel flow profile. A large percentage of tested students revealed false beliefs relating to transitions. For example, more than 50 percent of tested students drew a decrease in water depth for a subcritical drop, rather than an increase in depth. Students also had difficult in labeling subcritical, critical, and supercritical places along flow profiles and how water flows over or under different weir structures. Repairing these fundamental misconceptions is essential for students to be able to apply these concepts in diverse situations and learn more advanced topics.
全国都在呼吁识别科学和工程方面的先入之见和误解。识别误解可以为改进研究型课程的开发和实施提供基础。对这些概念的错误信念和有缺陷的心理模型的认识也有助于概念变化的理论。本研究的目的是找出与明渠水流有关的误解。2011年春季和秋季,在“水资源工程”两个专业的91名学生中,有50名学生接受了面试,41名学生接受了前后测试。这些开放式访谈和前后测试的目的是获得学生对开放通道流量概念理解的详细数据。结果表明,学生对水力和能量等级线(HGL/EGL)、流动过渡和流动剖面存在误解。许多学生有正确的HGL和EGL术语,但缺乏对术语在明渠流剖面上的位置的理解。接受测试的学生中有很大一部分透露了与过渡有关的错误信念。例如,超过50%的受测学生在亚临界下降时画出了水深的减少,而不是深度的增加。学生们在标记沿流动剖面的亚临界、临界和超临界位置以及水如何流过不同堰结构或在不同堰结构下流动方面也有困难。纠正这些基本的误解对于学生能够在不同的情况下应用这些概念并学习更高级的主题至关重要。

A new model for building and measuring analog electronic circuits has been developed and validated in the area of remote laboratories. The goal of the proposed solution is to facilitate and improve the set-up, maintenance and update of the hardware used during the configuration, control and measurement of the instruments and experiments included in the lab. The experimental setup does not reduce the performance of the lab, allowing the users to carry out the same actions and activities as they were in a hands-on laboratory. Therefore, thanks to this new paradigm users can practice through Internet and transparently to the hardware that makes possible the remote configuration of the experiments obtaining the same results as in a hands-on lab.

One of the most important subjects in the educational background of electrical engineering as well as in other important scientific areas of knowledge is the Signals and Systems Theory (SST). Taking into account the connection of the SST with the algebraic representation and the mathematical understanding of physical problems - electromagnetic radiation, scattering and inverse problems in our particular case -, a generalized scheme of the SST (GSST) is currently under development. While the usual point of view of classical SST is valid for practical purposes, it usually avoids many important concepts which become fundamental in the generalization of the analysis of physical problems. Some examples of this generalization are concerned with representations of physical problems different from those in the usual time-frequency domains - using a general variable -, the description of the problem in terms of infinite dimensional vector spaces and the algebra associated, the description of the Dirac delta function in terms of the distribution theory, etc. The most important purpose of obtaining a GSST is to connect the usual SST with important mathematical representations that lead to obtain more general representations that may be rigorously applied to model general physical problems. This generalized theory is focused on the algebraic concepts of signals and operators spaces, identifying each problem into their corresponding vector spaces and representing it in terms of the GSST scheme. One important point within this generalization is the concept of the Generalized Transform. Choosing a set of functions which play the role of a base, each signal of the space may be expressed in terms of a Generalized Linear Combination operator of this base weighted by a set of coefficients which identify the transform - their expression is directly related to the metric defined initially in the associated algebra -. Spectral analysis of systems is also contemplated, representing the signals in terms of their coefficients once a set of basis functions is chosen. The generalized theory let to obtain integral characterizations of linear systems - invariant and non invariant -, leading to the Generalized Spectral Analysis concept, closely connected to the operator theory. While the mathematical analysis of the GSST and its application, for instance to generalize the Green's function theory, has already been presented in several symposium - like 2009 IEEE AP and URSI Meeting -, a software tool based on the GSST is being worked out in parallel to the theoretical works.

信号与系统理论(SST)是电气工程教育背景以及其他重要科学知识领域中最重要的学科之一。考虑到海表温度与代数表示的联系以及对物理问题的数学理解-在我们的具体情况中是电磁辐射、散射和逆问题-目前正在开发海表温度的广义格式(GSST)。虽然经典海表温度的通常观点对实际目的是有效的,但它通常避免了许多重要的概念,这些概念在物理问题的推广分析中是至关重要的。这种推广的一些例子涉及到不同于通常时频域的物理问题的表示——使用一般变量——用无限维向量空间和相关代数来描述问题,用分布理论来描述狄拉克函数,等等。获得GSST最重要的目的是将通常的SST与重要的数学表示联系起来,从而获得更一般的表示,这些表示可以严格地应用于一般物理问题的建模。这个广义理论集中在信号和算子空间的代数概念上,将每个问题识别到相应的向量空间中,并用GSST方案表示。这个推广中的一个重点是广义变换的概念。选择一组函数作为基,空间的每个信号都可以用基的广义线性组合算子表示,该算子由一组确定变换的系数加权-它们的表达式与最初在相关代数中定义的度量直接相关-。系统的频谱分析也被考虑,一旦选择了一组基函数,就用它们的系数来表示信号。广义谱分析理论使我们能够得到线性系统的不变和非不变的积分特征,从而产生了与算子理论密切相关的广义谱分析概念。虽然GSST的数学分析及其应用,例如推广格林函数理论,已经在几个研讨会上提出,如2009年IEEE AP和URSI会议,一个基于GSST的软件工具正在与理论工作并行开发。本工具的目的是促进学生和实际的科学和工程师对这个广义方案的主要代数概念的理解,提供了五个不同信号空间中的多信号和多系统的一些例子。用户可以选择具有适当参数的信号和系统,并分析系统以及输出信号在实谱域和不同谱域的特性。这个工具的最后一个版本,SSTv4.5,可以分析线性非不变系统,并将脉冲响应集合可视化,以及在傅里叶变换、希尔伯特变换或贝塞尔变换(取决于信号空间)下的谱分析,从而举例说明广义谱分析的一些特殊情况。本文对该软件工具的当前版本进行了描述。

Taking into account the connection of the SST with the algebraic representation and the mathematical understanding of physical problems - electromagnetic radiation, scattering and inverse problems in our particular case -, a generalized scheme of the SST (GSST) is currently under development. While the usual point of view of classical SST is valid for practical purposes, it usually avoids many important concepts which become fundamental in the generalization of the analysis of physical problems. Some examples of this generalization are concerned with representations of physical problems different from those in the usual time-frequency domains - using a general variable -, the description of the problem in terms of infinite dimensional vector spaces and the algebra associated, the description of the Dirac delta function in terms of the distribution theory, etc. The most important purpose of obtaining a GSST is to connect the usual SST with important mathematical representations that lead to obtain more general representations that may be rigorously applied to model general physical problems. This generalized theory is focused on the algebraic concepts of signals and operators spaces, identifying each problem into their corresponding vector spaces and representing it in terms of the GSST scheme. One important point within this generalization is the concept of the Generalized Transform. Choosing a set of functions which play the role of a base, each signal of the space may be expressed in terms of a Generalized Linear Combination operator of this base weighted by a set of coefficients which identify the transform - their expression is directly related to the metric defined initially in the associated algebra -. Spectral analysis of systems is also contemplated, representing the signals in terms of their coefficients once a set of basis functions is chosen. The generalized theory let to obtain integral characterizations of linear systems - invariant and non invariant -, leading to the Generalized Spectral Analysis concept, closely connected to the operator theory. While the mathematical analysis of the GSST and its application, for instance to generalize the Green's function theory, has already been presented in several symposium - like 2009 IEEE AP and URSI Meeting -, a software tool based on the GSST is being worked out in parallel to the theoretical works. The aim of this tool is to facilitate both students and practical scientific and engineers the understanding of the main algebraic concepts of this generalized scheme, providing some examples of many signals and many systems in five different signal spaces.

We provide results from a nationwide survey of advertisements for jobs in the technology sector. This snapshot of 521 job postings provides an interesting glimpse into the state of the computing industry in the U.S., quantifying the programming languages most frequently requested by employers today. This study reveals industry preference for Java and C++ skills. C++ is requested most frequently in the South Atlantic Region and was also favored on the west coast. Additionally, SQL skills were more requested for positions related to testing, JSP skills were more requested in architect positions, and both C and C++ were more requested in analyst positions. While academic practices should not be based solely on industry practice, industry demand for languages serves as one useful data point when institutions make pedagogical choices.
我们提供了一项针对科技行业招聘广告的全国性调查结果。这张521个招聘启事的快照提供了一个有趣的视角来了解美国计算机行业的现状,量化了当今雇主最常要求的编程语言。这项研究揭示了行业对Java和c++技能的偏好。c++在南大西洋地区最受欢迎,在西海岸也很受欢迎。此外,与测试相关的职位更需要SQL技能,架构师职位更需要JSP技能,分析师职位更需要C和c++技能。虽然学术实践不应该仅仅基于行业实践,但行业对语言的需求可以作为机构做出教学选择时的一个有用的数据点。
