Effective teaching of computational methods to economists in an introductory graduate-level course requires difficult choices regarding the material to be covered, the level at which the material will be covered, and the role of assigned exercises, laboratory sessions, and required readings. In this paper, I discuss the goals that I set and the pedagogical choices that I make in teaching computational methods to doctoral students in economics in a quarter-length course. The discussion is based on 15 years of teaching computational methods to students with a broad range of research interests and professional objectives. I also discuss some of the pedagogical obstacles that I often face when teaching the course and how I address them. I hope that the discussion will provide a useful starting point for instructors wishing to develop computational methods courses in other economics graduate programs. 相似文献

Abstract To become proficient problem-solvers, physics students need to form a coherent and flexible understanding of problem situations with which they are confronted. Still, many students have only a limited representation of the problems on which they are working. Therefore, an instructional approach was devised to promote students' understanding of these problems and to support them in forming associations between problem features and solution methods. The approach was based on using the computer algebra software Mathematica as a tool for problem solving and visualisation. An electrostatics course module was implemented based on this instructional approach, and this module was compared with a usual paper-and-pencil based one. Learning outcomes for both courses were not significantly different. The experimental course was found to impose a high cognitive load on the students. Based on the outcomes, proposals are made for ways in which the course could be improved. 相似文献

Young economists sometimes ask which computer programming languages they should learn. This paper answers that question by suggesting that they begin with a high level language like GAUSS, GAMS, Mathematica, Maple or MATLAB depending on their field of specialization in economics. Then they should work down to one of the low level languages such as Fortran, Basic, C, C++ or Java depending on the planned areas of application. Finally, they should proceed to the languages which are used to develop graphical interfaces and internet applications, viz. Visual Basic, C, C++ or Java. 相似文献

Computer vision algorithms are strongly based on advanced mathematical methods. Tools to efficiently develop new methods are increasingly based on computer algebra systems, such as Matlab, Maple and Mathematica. For rapid prototyping both symbolic as numerical capability is required. However, the application to large datasets such as images has always been frustated by the expensive use of memory or long computing times. Today such programs have improved substantially in numerical data handling, making them an ideal tool for rapid prototyping in computer vision. This paper gives a short variety of examples of the use of Mathematica in computer vision research. 相似文献

Our concern in this paper is that the capability of economics undergraduates is substantially underestimated in the design
of the present college curriculum and that our students are insufficiently challenged and motivated. Students enter our classrooms
with substantial previous knowledge about computers and computation and we are not taking full advantage of this opportunity.
We suggest a set of examples from computational economics which are challenging enough to motivate students and simple enough
that they can master them within a few hours. By encouraging the students to modify the models in directions of their own
interest, avenues for creative endeavor are opened which deeply involve the students in their own education. 相似文献

该文以126名中国大学生为测试样本,并采用非独立t检验为计算方法,讨论英语花园幽径句解码效果与解码反应时之间的关联性。花园幽径句是能引发行进错位的局部歧义句,大学生在歧义消解过程中易产生认知困惑。在其他条件不变的情况下,先后两次的语言实验将单样本花园幽径句的反应时从5s延长至10s,并进行了相应的t值计算。S1实验中,测定5s反应时和10s反应时的非独立t检验值为3.71,大于理论临界值并具有显著性差异。在S2-S100的实验中,分析发现材料的选择对实验结果有影响。总体而言,英语花园幽径句解码效果与解码反应时之间具有一定关联性,阅读时间的延长可以在一定程度上帮助学生更好地消解局部歧义。 相似文献

MathLink is Wolfram Research?s protocol for communicating with the Mathematica Kernel and is used extensively in their own Notebook Frontends. The Mathematica Book insinuates that linking C programs with MathLink is straightforward but in practice there are quite a number of stumbling blocks, in particular in cross-language and cross-platform usage. This write-up tries to clarify the main issues and hopefully makes it easier for software authors to set up Mathematica interfacing in a portable way. 相似文献

生物信息学是当今自然科学重要前沿领域之一。随着基因测序技术的进步,大量生物数据需要计算机来处理和分析,对生物信息学人才的要求越来越高。“大学计算机基础”作为大学新生的必修课程,其教学目标之一就是让学生具备基本的信息处理能力——不仅要学会计算机,还要掌握利用计算机来解决实际问题,特别是解决专业问题,这对学生的编程能力提出了一定要求。而Python程序设计语言因学习入门难度低,是一非常适合低年级及非计算机专业大学生学习的编程语言,通过学习编程能培养学生的计算思维和提高解决问题的能力。在生物专业的“大学计算机基础”课程中加入Python程序设计内容,对生物信息学人才的培养具有很强的现实意义。 相似文献

This note describes a Mathematica interface for Fortran code generated by FormCalc. The interfacing code is set up automatically so that only minuscule changes in the driver files are required. The interface makes a function to compute the cross-section or decay rate available in Mathematica. This function depends on the model parameters chosen for interfacing in the Fortran code. 相似文献

Analytica is an automatic theorem prover for theorems in elementary analysis. The prover is written in the Mathematica language and runs in the Mathematica environment. The goal of the project is to use a powerful symbolic computation system to prove theorems that are beyond the scope of previous automatic theorem provers. The theorem prover is also able to deduce the correctness of certain simplification steps that would otherwise not be performed. We describe the structure of Analytica and explain the main techniques that it uses to construct proofs. Analytica has been able to prove several nontrivial theorems. In this paper, we show how it can prove a series of lemmas that lead to the Bernstein approximation theorem. 相似文献
