effectivelydelivering those skills to a linguistically and academically diverse group of engineering students.IntroductionOver the past couple of decades, research experiences for undergraduates (REUs) have becomean increasingly popular and effective way for engineering students to explore the world ofresearch. These programs come in an array of choices of topic, location, program goals,enrollment, and duration.1 Most of the papers published about REUs tend to discuss eitherresearch approaches, “how-to” run a program, or assessment.2Some programs assess their success based on future graduate school matriculation of theirformer students, or on the number of publications or conference papers for which these studentsare listed as co-authors.3-6 That a publication

group environment • Establishing peer assessmentLearning in TeamA team is a group of people actively cooperating in an organized way to achieve a goal. .Learning in groups depends upon the synergy in a group. The assumption is the whole is morethan the sum of the parts. Learning from each other and supplementing each other’s strongattributes is the key in learning in groups. The relative effectiveness of different environmentshas shown the superiority of the learning in groups[ 1]. Students working in cooperative learninggroups, relative to the other situations learn more. They also have more positive attitudesregarding the subject area.

The survey is a modified version of one used by Atman et al. at theUniversity of Washington in their freshman design course5. As Atman and co-workers explain,the validity and utility of the instrument to describe changes in students’ attitudes aboutengineering, and perceptions of their abilities, have been established by previous studies 6,7.Students rated their confidence level on a 1-6 point scale. The purpose of these 26 items was toprovide insight into students’ confidence in their knowledge and skills, and how theseperceptions might have changed as a result of EDC.Each of the items is related to the goals of the course as well as

A key finding of their research is that integrating AI and philosophy of the mindcan appeal to a broader audience and result in high student interest and achievement. In thispaper we build upon Ellis and Andam’s work by presenting a conceptual framework that usesphilosophy of the mind to organize how students learn about AI. Our approach acknowledgesthat intelligence is a complex issue involving philosophical concerns that must be addressed inorder to develop intelligent machines.Using philosophy to organize AI content significantly

”IntroductionCivil Engineering by its nature often involves design of one of a kind structures that must servethe public. These structures must be designed, without prototype, to maintain the public’s safety,i.e. not fail. Getting it right is critical! This is a fact that has been recognized since the earliestwritten laws: Hammurabi’s code stated as early as 1780 BCE “229 If a builder build a house forsome one, and does not construct it properly, and the house which he built fall in and kill itsowner, then that builder shall be put to death” [1]. There are several other laws, numbers 230through 233, that deal in a similar vein with building failure and offer similar dire consequencesin an effort to stress the importance of getting it right.

In brief, we have argued previously that students do not readily appreciate theforces between inanimate objects. As a consequence, we have devised means of teaching most ofthe primary concepts in Statics, first with recourse only to forces which students can immediatelyperceive, through the senses of touch and sight. That approach involves students manipulatingand balancing objects, contemplating relevant conceptual questions and debating with peers.These in-class experiences, comprising the objects and the PowerPoint

In contrast to lecture basedteaching, the project - based method (one that is time-tested in architectural design schools)mimics architectural industry, where information is often dispensed in meetings rather than informal lectures. This paper addresses the dearth of architectural research that focuses upon designmethods and education. Most research done by architectural educators, as noted by Voyatzaki 1 Page 10.113.1

The mechanical engineering Statics course at CMU is given over asemester of 14 weeks, with 3 hours of lecture and 1 hour of recitation per week. Nearly allstudents in the class are sophomores in mechanical engineering. They have taken a 3 creditintroduction to mechanical engineering class in the freshman year, which touches on many ofthe basic subjects in mechanical engineering (and gives them exposure to design and CAE aswell).

is a microcontroller that has been in the market since 1980 2 and Motorolahas discontinued the manufacture of this product. It became difficult to find the supplier for thischip and its price is higher than expected. After a study of the specifications and potentialapplications on SPI 11, I2C 8, and SMBus 12,13, an idea has surfaced to revise the designs on theelectronic hardware and software to use multiple and cheaper CPUs, such as Microchip’s16F84A in a form of serial communication links 8,11,13. The 16F84A is a popular 8 bitmicrocontroller in many places and the vender suppliers are plentiful 1.
