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

9351449 Anderson所有科学专业要求的物理入门课程“物理基础I和II”的实验室序列已经重新设计和升级，通过增加计算机辅助实验室（CAL），重点是多概念实验（MCE），并采用“最先进的”数据采集技术。虽然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。正在实现的MCE系列基于磁弹性现象；简谐运动与共振；弹性性能、声速和模量；阻尼、Q和效率；感应磁场；还有铁磁性，磁导率和磁致伸缩。正在使用CAL软件，它可以在不同的计算机平台之间移植，并且可以很容易地进行编程，以进行任何类型的实验的复杂控制和分析。所选择的软件- Lab View II -采用真实和虚拟仪器。学生只需使用窗口界面选择实验。在回顾了程序并进行了可选的教程和模拟之后，学生们使用真实和虚拟仪器建立了实验。计算机辅助教学模块（不属于本补助金的一部分）使学生能够自主学习和复习课程内容，包括实验室经验。＊＊＊

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. ***
