Slower students will be accommodated by being given the complete set of notes and ask to underline the key words other students are writing down. Slide shows are equipped to click on voice over buttons (created by advanced students,) so the slide show can be read to those who need it on an individual basis. Advanced students improve the PowerPoint lectures for various chapters. They add voice over, modify pictures, find movie clips, website links, etc, and can chose from a list of independent project challenges.

18 Permission granted to reproduce for educational use only. © Goodheart-Willcox Co., Inc. The Technological System

19 Permission granted to reproduce for educational use only. © Goodheart-Willcox Co., Inc. Outputs The desirable outputs of technological systems satisfy a technological problem or opportunity. There can also be undesirable outputs, however, like pollution, soil erosion, or other problems. The intended outputs are expected and may be desirable or undesirable. Unintended outputs, which were not expected, may also result from systems.

20 Permission granted to reproduce for educational use only. © Goodheart-Willcox Co., Inc. Immediate and Delayed Outputs Most technological systems are designed to produce a product or service for use now, which results in immediate outputs. Aerosol cans and sulfur dioxide eventually creating pollution are examples of delayed outputs.

21 Permission granted to reproduce for educational use only. © Goodheart-Willcox Co., Inc. Feedback and Control We can view internal control systems from three different angles: –Types of control systems. –Components of control systems. –Operations of control systems. There are also external controls, such as political actions and personal value systems, to be considered.

23 Permission granted to reproduce for educational use only. © Goodheart-Willcox Co., Inc. Review What effect do feedback and control have on outputs in technological systems? Outputs are the results of the system that are, in turn, modified or corrected by feedback and control.

24 Permission granted to reproduce for educational use only. © Goodheart-Willcox Co., Inc. Review How are outputs categorized? Outputs are categorized in three ways: desirable/undesirable, intended/unintended, and immediate/delayed.

25 Permission granted to reproduce for educational use only. © Goodheart-Willcox Co., Inc. Review What are the desirable and undesirable outputs of transportation technology? The desirable output is the movement of goods and people, while the undesirable output is the fumes and toxic by-products of different modes of transportation.

26 Permission granted to reproduce for educational use only. © Goodheart-Willcox Co., Inc. Review Define feedback as used in technology systems. Using information from the output of a system to control or regulate the system or its inputs to affect the output.
