研究表明，实践，实验学习对于参加大学工程课程的学生的成功至关重要。这导致大学变得越来越关注寻找不断提高的方式，为学生提供动手学习的机会。传统的校园实验室非常有帮助，但它们可能会受到限制。学生必须共享设备，并且经常发现自己是一个团队的一部分，在该小组中，并非每个学生都有机会真正获得设备。大学竭尽所能提供长时间的实验室时间，但许多学生仍然发现无法获得实验室设备的动手时间。研究人员继续寻找解决此问题的解决方案，并在题为“Remote Circuit Design Labs with Analog Discovery,” three researchers examine the use of Digilent’sAnalog Discoveryas a means of increasing hands-on learning in two separate Circuits courses.
从纸上：
Digilent的模拟发现是一个小型的便携式电路设计站，它非常适合实验学习。已经证明，对于学生来说，有机会在大学职业生涯中早期进行动手实验学习很重要。已经证明，早期接触此类学习可以增加学生的学习成果和工程课程中的学生保留率。因此，许多大学正在开发课程，这些课程将为新生提供足够的动手学习机会。2012年，一所大学的电子工程技术系决定在其电路I和II课程中使用Digilent的模拟发现。这些课程是独一无二的，因为唯一的先决条件是预算，这使得第一年和二年级的学生可以进入。
Below is a list of topics covered in these two courses.
- Voltage and Current
- 反抗
- Ohm’s Law, Power, and Energy
- 系列DC电路
- 平行直流电路
- Network Theorems
- 电容器，电感器和磁回路
- Sinusoidal Alternating Waveforms
- 基本元素和取代
- Series and Parallel AC circuits
- Network theorems AC circuits
- 功率和共鸣
- 变压器
- Polyphase systems
Normally, students would only be able to perform the labs in these courses on campus, but with the help of the模拟发现，students can work on homework, and practice the skills associated with these labs from virtually anywhere. As it says in the paper, “The Digilent Analog Discovery design kit, developed in conjunction with Analog Devices Inc., is the first in a new line of all-in-one analog design kits that will enable students to quickly and easily experiment with advanced technologies and build and test real-world, functional analog design circuits anytime, anywhere – right on their PCs.” The Analog Discovery is a “low cost and portable test and measurement device, which provides various instruments including two oscilloscope probes, two arbitrary waveform generators, two power supplies, a voltmeter, a logic analyzer, and a pattern generator in a single module.” Every student needs their own Analog Discovery, and according to the paper, “an acquisition of a large number of these mobile Analog Discovery modules for an introductory class shall prove to be quite an ideal solution.”
Below is a list of labs conducted in both Electric Circuits courses, for which the Analog Discovery could be used:
在电路I中，进行了以下实验室：
- Series/Parallel DC circuits
- Superposition Theorem (DC)
- Thevenin和Norton的定理
- RC, RL and RLC circuits
In Electric Circuits II the following labs are conducted:
- 示波器
- R-L-C组件
- Frequency response of series RC, RL and RLC circuits
- Superposition Theorem (AC)
Last but not least, the flexibility of theAnalog Discovery允许学生组建一个学生铅外展小组（SLOG）。一个口号有两个主要目的：
1.将电子工程技术意识传播到代表性不足的群体，当地社区，预科课和中学后学生，以及使用模拟发现套件的外展示范项目以及教师。
2. To assist students who need help at any location 24/7.
With the Analog Discovery, Student Lead Outreach Groups will be able to bring experimental, hands-on learning to groups who would otherwise have no access to such information and valuable experience. It can even help increase high school students’ interest in engineering, and help prepare future engineering students for what lies ahead.
Overall, theAnalog Discoveryis an excellent addition to any Electrical Engineering Technology Program. Use of the Analog Discovery as a means of increasing hands-on learning and creating remote labs can lead to “higher matriculation rates, increased retention, and ultimately a higher graduation rate.” Both instructors and students were very pleased with the Analog Discovery as a means of supplementing the traditional on-campus lab experience. The Analog Discovery is portable, flexible, and affordable, making it an invaluable tool for both introductory, and upper division college courses.
