needs of these under-prepared students have focused on teachingcontent courses together with a variety of academic/study skills strategies. These have met with limitedsuccess. Our department has recently (2005/2006 academic year) received a National Science Foundation(NSF) Course Curriculum and Laboratory Improvement (CCLI) Phase I grant to apply “Self-RegulatedLearning” (SRL) to two engineering technology courses. SRL involves teaching students a new way ofunderstanding their learning process and how to monitor and manage it. The SRL process includes an on-going three-phase cycle: (1) planning, (2) practicing and (3) evaluation. During the planning phase,students assess prior performance, set goals and choose appropriate learning strategies

analogsignal. Digital control is the simpler of the two control methods since only an on/offsignal need to be received by the device. For a solenoid valve a 5 volt signal might turnthe valve on while a zero volt signal would turn the valve off. An electrical heater isanother example of a device that can work with either digital or analog control. Theheater can either be on or off, digital control, or we can vary the current to the heater,proportional control. To send these signal we simply need an electrical switch. A simpleelectrical switch available commercially is called solid state relays. Other electricalswitches are available.The students also master the following skill list:1.

applications of feedback control techniques.1. IntroductionThe ball-on-beam balance system is a classic example of feedback control systems. The problem is tomaintain the position of a ball at the center of a beam on which the ball rolls along freely. The ball willreturn to the center position after it has been displaced from this location. This system is an effectiveeducational tool for teaching feedback control principles. Some of these systems are commerciallyavailable[1,2,3].The set-up of our ball-on-beam system is shown in Fig. 1. The beam is a 55” long, grooved aluminumbeam that a regular rubber ball can roll along freely. The beam is mounted at the center to a servo motor,which can tilt the beam in clockwise and counter-clockwise directions

investigation of cognitive learning within the engineering profession is rather new, it hasbeen accepted by other fields of education with the most notable being the study of medicine. Untilrecently, the four-year medical school experience centered around lecture and laboratory work, somewhatsimilar to engineering education, with clinical work occurring primarily during the fourth year. Todaymany medical schools include clinical experience early in the medical school experience because studentshave demonstrated a better grasp of material when they are concurrently studying in “traditional” coursesand experience greater cognitive learning through the combination of clinical (problem-based learning)and lecture activities.1 A similar inclusion of

Theseland invaders or “Invasores” as they are called in the local community staked their claims by buildingsmall shacks on parcels of land. These dilapidated houses were built quite literally using any materialsthat the people could get their hands on. Over time these communities grew as the walls of one housebecame the walls of the next. One of these neighborhoods, called Luz Consuelo, is shown in the satellitephotograph in Figure 1.

This change was made for all eight engineering programs such that all engineeringstudents would experience a common curriculum during the first year. Many benefits have resulted fromthis change over the past decade including the following highlights: • Retention of engineering students from the freshman year to the sophomore year increased from ~60% to ~72% (see figure

horrible accidents whenhumans contact high voltage. In this article we cite 3 cases of high voltage accidents.Each accident teaches something different about electricity and electric safety.Let us first begin with some clarifications. By formal definition, high voltage is definedas any voltage above 600 volts. Below 600 volts, one should consult the NEC (NationalElectric Code) for the rules of electrical installation and safety [1]. Above 600 volts, thebetter safety code is written by OSHA [2]. This should not in any way diminish thedanger of low voltage circuits. People die in their homes every day from electrocutioncaused by 120 and 220 volt sources.

Mechanical properties of composites are a function of those of the ingredients, as wellas their relative fraction amounts, and how the dispersed phase is distributed. The distribution ischaracterized by type/shape of the dispersed phase particles, size of the particles, as well orientation anddistribution.Distribution of fibers in fiber-reinforced composites is varied as per the application or load to be carried.These types are (1) continuous fiber

insufficient figures to illustrate these rules. This paperwill discuss the author’s attempt to address this problem.Force on a spur gearWhen two spur gears are meshed shown in Fig. 1, and the left one is the driver, the contact pointmoves along a line as the gears rotate, as shown in Fig. 2. The line of action is sometimes calledthe pressure line. The force pushing the driven gear is shown in Fig. 3, and will always be alongthis line of action. The type of force is bearing (pushing) force, applying pressure to the matingtooth. From the principal of force transmissibility in statics, we know that any point along theline of action will still create the same torque about the gear. Therefore, we can use a fixedcontact point (pitch point) to simplify the

Through simple qualitative discussion and demonstration the students were introduced to the fact thatfor every object, regardless of its shape and size, when freely suspended from any point on the shape, aplumb line will always pass through the center of mass. Using two points not on the same line of “masssymmetry” will result in an intersection which is the mass center of the object as illustrated in Figure-2.During this experiment the principal of gravity and how it works was explained and

(See Felder, 2004.) A recent, andwidely publicized, illustration of the trend was the creation in 1997 of the Olin College ofEngineering. The Olin Foundation made a $300 million investment to establish a new college ofengineering that would integrate project work in all four years of the new curriculum.(Somerville, et al, 2005).For almost 20 years, there has been significant investment by the National Science Foundationintended to increase

The United States Green Building Council has established an industry standard in Green BuildingRating Systems with their Leadership in Energy and Environmental Design (LEED) certification. TheLEED certification process involves earning credits for environmentally friendly construction processesand materials and the use of efficient building systems. The certification has several tiers (gold, silver,etc.) for different levels credit.1 One way LEED credit can be earned is through use of recycled
