Students' understanding of how robotic ultrasonic sensors work is reinforced in a design challenge involving LEGO MINDSTORMS(TM) NXT robots and ultrasonic sensors. Student groups program their robots to move freely without bumping into obstacles (toy LEGO people). They practice and learn programming skills and logic design in parallel. They see how robots take input from ultrasonic sensors and use it to make decisions to move, resulting in behavior similar to the human sense of sight but through the use of sound sensors, more like echolocation. Students design-test-redesign-retest to achieve successful programs. A PowerPoint® presentation and pre/post quizzes are provided.

Students learn how to build simple piezoelectric generators to power LEDs. To do this, they incorporate into a circuit a piezoelectric element that converts movements they make (mechanical energy) into electrical energy, which is stored in a capacitor (short-term battery). Once enough energy is stored, they flip a switch to light up an LED. Students also learn how much (surprisingly little) energy can be converted using the current state of technology for piezoelectric materials.

In the everyday electrical devices we use calculators, remote controls and cell phones a voltage source such as a battery is required to close the circuit and operate the device. In this hands-on activity, students use batteries, wires, small light bulbs and light bulb holders to learn the difference between an open circuit and a closed circuit, and understand that electric current only occurs in a closed circuit.

This single instrumental qualitative case study explores and thickly describes job performance outcomes based upon the manner in which self-directed learning activities of a purposefully selected sample of 3 construction managers are conducted, mediated by the use of Web 2.0 technology. The data collected revealed that construction managers are concerned with the performance expected of them, in addition to how well they perform their work-related activities (orientation to learning), indicating that organizations should provide guidelines on the use and expected outcomes of self-directed learning in addition to providing the tools, resources, and time (environmental factors) to match performance needs; construction managers feel that work-related activities expected of them, how well the work-related activities are performed, and consequences for poor performance at work are determining factors in selecting Web 2.0 technologies; while construction managers understand the need for rules restricting the use of Web 2.0 technologies in performing their jobs, they feel these rules do hinder their performance because access to specific information they need to answer a question, solve a problem, or research to learn something new is sometimes restricted; and successful performance outcomes are determined by compliance to expected performance behaviors of others, such as answering a question or solving a problem an architect or superintendent have presented, as well as expectations construction managers have set for themselves. The following are appended: (1) Call for Participation--Web 2.0 Technology Project; (2) Informed Consent Letter and Form/Template; (3) Semistructured Interview Guide; and (4) Permission to Conduct Research Study.
