We have begun toapply progressively this Method in the Structures courses, of which we are professors.The use of the Experimental Methodology helps to reorganize student´s knowledge, improvingthe connections between different concepts in different subjects, and puts them in contact withthe resolution of engineering problems that will appear in their future professional activities.We have also observed that this Method encourages students to deeper researches of thestructural problems, thus helping them to achieve higher levels of knowledge as independentthinkers, according to

A psychological tool in sociocultural discourse is virtually anyinstrument connected with conceptual thought—calendars, the computer, maps, mechanicaldrawings, and works of art to name a few. One’s mental functioning is tied to the cultural andsocial settings in which the individual masters the tools s/he uses to help reason through asituation. The tools become carriers of the sociocultural patterns of knowledge, which theindividual actively engages and at the same time influences.Some recent research on problem

This problem was chosen for the following reasons: • It could be solved in a number of different ways. • It could be described by top-level blocks. • It was a project previously managed and known in detail by the instructor. • It required knowledge of redundancy and reliability to solve the problem.Reliability is a key element in the design of a multiprocessor computer for critical applications.The normal way to achieve the high reliability is to use redundancy techniques.

TheNN is then trained by presenting it with many sets of training data where a set consists of a value foreach input and the corresponding desired output(s). From this training data, the NN calculates(learns) the input weights for each neuron so that the NN output closely matches the correspondinginput for each point in the training data. This learning process is an iterative back propagationalgorithm. The learning process is terminated when the NN’s predicted output(s) matches the desiredoutput(s) for each set in the training

The affective domain is the one that describes the attitudes of the student toward the subject matter, education, and lab activities. This domain is very important in setting the ground rules for the lab environment. It greatly affects the student performance and education without being clearly visible. 2 iii. Psychomotor Domain

At the same time, the nature of computer applications has changed. The mass adoption ofdesktop personal computers and the development of powerful applications for them haveprovided many useful alternatives and/or replacements for traditional mainframe applicationsthat have existed since the mid 1960's. At the same time, the need to understand traditionalanalytical engineering theory and problem solving techniques has not diminished.

Two of these engineers (artists, patriots, etc.),Charles Willson Peale and Thomas Paine, were bridge designers, and another, JohannChristopher Christensen designed and supervised construction of America’s first poweredwaterworks. Engineering student teams at Bucknell have studied these early designs and usedthem as a basis for senior design projects. Based upon their evaluation of the historic designs, theteams produced their own designs of replicas of the early works, and then they built and testedthem. Because of the relative simplicity of the 18th Century designs, students applied engineeringprinciples to them and saw new meaning in the fundamental concepts that they employed. Theyalso
