1. Abilities for a Technological World Unit E

2. Students will develop abilities to use and maintain technological products and systems National Standard 12

3. Apply technological tools and systems to real world experiences. Objective 5.00 Objective 5.01 Explain the concepts used to develop and maintain technological products and systems. Objective 5.02 Use computers and other tools of technology in various applications.

4. To achieve the previous objectives students will be able to apply information provided in manuals, protocols, or by experienced people to see and understand how things work.

5. A student reads an instructional manual and follows an on-screen tutorial in a multimedia module

6. The technology students of today learn in many different ways.

7. Modular Lab Some labs have gone totally modular, where the students follow a series of tutorials as they learn about technology.

8. Conventional Lab Other labs allow the student to learn through a series of teacher guided activities.

9. Whatever system is used, it is important for the student to develop the ability to use the resources around them to understand how our complex technological systems work.

10. Students will use tools, materials, and machines to safely build, diagnose, adjust, and repair systems.

11. Students must realize that FEEDBACK is information about the output of a system, and that it can be collected in many ways. A dragster is placed in a wind tunnel to collect aerodynamic data.

12. Once a student has this data, it can be used to monitor how a system is working, and then diagnose, adjust or repair the system to reach the desired goal.

13. As we made the switch from Industrial Arts to Technology Education, our use of tools and materials has changed dramatically. Along with these changes came a new series of safety concerns, not just for our students, but also for our equipment.

14. While the discharge of static electricity did little damage to a band saw, A student uses the band saw to cut out his truck for the TSA Transportation Modeling competition.

15. we must explain to our students how damaging it can be to a computer or other electronic devices.

16. Grounding strap Always use a grounding strap !

17. Students will be able to use computers and other tools of technology in various applications.

18. Interfaces; like the one attached to our robotic arm,

19. can be used to allow various devices to communicate with computers.

20. Students need to understand the operation of and properly use computers, calculators, and other electronic devices to help determine if a system is operating properly.

21. A student uses a multimeter to diagnose an electrical circuit.

22. As a system becomes more complex, the need to properly maintain the operation of a system also increases. Students assemble, program, operate, and adjust a robotic arm.

23. Students work on a digital video editing system. Proper maintenance of the equipment will ensure that the system continues to operate efficiently.

24. Students will need to access the data provided by sensors within a system to evaluate the operation of the various components making up the system, and make changes when necessary.

25. A Lego Mindstorms or ROBOLAB kit provides an excellent opportunity for students to investigate systems models.

26. Here are some examples of Lego sensors that can used by students in the lab to collect and monitor data and provide feedback to a system.

27. Temperature Sensor This sensor will allow students to monitor the temperature of something.

28. Light Sensor Students will be able to use the light sensor to monitor light from 0.6 to 760 Lux.

29. Touch Sensor This sensor allows students to identify when one item comes in contact with another.

30. Speed Computer Students will be able to use this sensor to measure speed in rotations or RPM’S, and to measure distance in inches or feet.

31. The understanding of how a system works is vital if students are allowed to operate and maintain it. Students working on the Systems Control problem at the TSA National Conference in Richmond Virginia.

32. Systems and sub-systems It will become increasingly important for students to become systems-oriented, and to realize that systems are made up of many sub- systems. Model rockets are made up of many sub-systems; ignition, propulsion, guidance, and recovery.

33. The components of the universal systems model, input, process, output, monitor, and feedback also need to be identified and used in activities whenever possible. INPUTPROCESSOUTPUT FEEDBACKMONITOR Universal Systems Model
