Cutting-edge technologies are reshaping manufacturing in the United States and around the world, with applications from medicine to defense. If the United States wants to further build upon these new innovations, the next generation of engineers must be trained to work in advanced manufacturing from the undergraduate level and beyond. Infusing…

Research shows that that children learn science and engineering subjects best by engaging from an early age in the kinds of practices used by real scientists and engineers. By doing science and engineering, children not only develop and refine their understanding of the core ideas and crosscutting concepts of these disciplines, but can also be…

The COVID-19 pandemic is resulting in widespread and ongoing changes to how the K-12 education system functions, including disruptions to science teaching and learning environments. Students and teachers are all figuring out how to do schooling differently, and districts and states are working overtime to reimagine systems and processes. This is…

Effective evidence-based action requires getting the right data into the right hands at the right time to help make decisions. The Data Quality Campaign (2011) has provided suggestions to state education agencies for effectively using data within state longitudinal data systems. One suggestion is to identify "the variety of ways available…

Service-Learning in engineering education is gaining ground throughout the country and throughout the variety of disciplinary focuses within engineering education. Examples of service-learning exist in mechanical engineering, construction science, computer science and engineering, electrical engineering, and other forms of related education.…

A review of the state requirements for engineering education reveals that the laws vary a great deal from state to state. Many laws contain special peculiarities that reflect various opinions about what constitutes the appropriate credentials for registration and reflect differing views concerning the methods as well as the importance of…

The manual is written primarily to aid in the training of personnel to meet the professional qualifications of the engineering aid, first class and chief. In chapter one, the trainee becomes familiar with the rewards and responsibilities of an engineering aid. Chapter two deals with principles of SEABEE administration, the organization and…

An analog/hybrid simulation of a Digital Volt Meter (DVM) and an incremental analog-to-digital (A-D) converter are presented. An analog simulation of planar frames is also presented. (MLH)

The method of phase-plane presentation as an educational tool in the study of the dynamic behavior of systems is discussed. In the treatment of nonlinear or piecewise-linear systems, the phase-plane portrait is used to exhibit the nature of singular points, regions of stability, and switching lines to aid comprehension. A technique is described by…

This booklet is designed to provide information to girls about the nature of and possible career opportunities in engineering. Following a brief introduction in which the characteristics of engineers are outlined (such as ability to solve problems, interest in science/mathematics, and urge to make creative use of their intelligence), answers to…

In certain boundary layer or natural convection work, where a similarity transformation is valid, the equations can be reduced to a set of nonlinear ordinary differential equations. They are therefore well-suited to a fast solution on an analog/hybrid computer. This paper illustrates such usage of the analog/hybrid computer by a set of…

An overview of recent developments in the theory of observers is presented, together with a simple design method that casts the problem in the form of a full order observer. Examples of observer performance are presented which are representative and suitable as demonstrations on small analog or hybrid computers. (Author/MH)

The simulation of a sampled-data system is described that uses a full parallel hybrid computer. The sampled data system simulated illustrates the proportional-integral-derivative (PID) discrete control of a continuous second-order process representing a stirred-tank. The stirred-tank is simulated using continuous analog components, while PID…

This paper describes an introductory course in microprocessors and microcomputers implemented at Grossmont College. The current state-of-the-art in the microprocessor field is discussed, with special emphasis on the 8-bit MOS single-chip processors which are the most commonly used devices. Objectives and guidelines for the course are presented,…

Described is an introductory materials science laboratory program which emphasizes crystal structure both on the atomistic and microscopic scale and the dependence of materials properties on structure. The content of this program is classified into four major areas: (1) materials science, (2) mechanical behavior of materials, (3) materials testing…
