Computer-Assisted Laboratory with Multi-Concept Experiments for Introductory Physics

9351449安德森所有理科专业必修的入门物理课程“物理学基础I和II”的实验室序列已重新设计和升级，增加了侧重于多概念实验的计算机辅助实验室，并采用了“最先进的”数据采集技术。尽管多概念方法通常需要复杂的设置和复杂的数据收集，但数据采集仪器的使用简化了此类实验的程序方面。正在实施的MCE系列基于磁弹性现象；简谐运动和共振；弹性特性、声速和模数；阻尼、Q和效率；感应磁场；以及铁磁性、磁导率和磁致伸缩。正在利用CAL软件，该软件可以在不同的计算机平台之间移植，并且可以很容易地编程来对任何类型的实验进行复杂的控制和分析。选定的软件-Lab View II-使用真实和虚拟仪器。学生们只需使用一个窗口界面来选择实验。在回顾了过程并执行了可选的教程和模拟后，学生们使用真实和虚拟仪器设置了实验。计算机辅助教学模块(不包括在本助学金中)使学生能够进行自定进度的学习和复习课程内容，包括实验经验。***

9351449 Anderson The laboratory sequence of the introductory physics courses required of all science majors, "Fundamentals of Physics I and II", have been redesigned and upgraded through the addition of computer-assisted laboratories (CAL) that focus on multiple concept experiments (MCE), and that employ "state-of-the art" data acquisition techniques. Although the multi-concept approach normally entails complicated set-ups and complex data collection, the use of data acquisition instrumentation simplifies the procedural aspects of such experiments. The MCE series being implemented are based on magnetoelastic phenomena; simple harmonic motion and resonance; elastic properties, speed of sound, and modulus; damping, Q and efficiency; magnetic fields in induction; and ferromagnetism, permeability, and magnetostriction. CAL software is being utilized that is portable between different computer platforms and that can be easily programmed to do sophisticated control and analysis of any type of experiment. The selected software - Lab View II - employs real and virtual instruments. The students simply use a window interface to select the experiment. After reviewing the procedure and performing an optional tutorial and simulation, the students set-up the experiment using both real and virtual instruments. Computer-assisted instructional modules (not part of this grant) enable students to engage in self-paced study and review of course content, including the laboratory experience. ***
