PowerPoint also includes short video clips & web links. Desk Activity (10 minutes, Approximately) Vocabulary Students write each word multiple times and define each word. Test Your Knowledge Students answer designated summary questions for the chapter. Study with the FoundationsofTechnology.com websiteFoundationsofTechnology.com Projects / Computer Activity (28 minutes Approximately) Closure (Review of 5 minutes, Objectives Approximately) Homework: (if applicable) Finish Vocabulary / Objectives / Test Your Knowledge Study with the FoundationsofTechnology.com websiteFoundationsofTechnology.com Modifications to meet student needs (IEP, ILP, ELL and Special Needs) Modifications to meet student needs (Enrichment) Students with writing difficulties may write the objectives later. 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.

Day 1 Outputs and Feedback and Control Slide 18 Permission granted to reproduce for educational use only. Goodheart-Willcox Co., Inc. The Technological System Slide 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. Slide 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. Slide 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. Slide 22 Permission granted to reproduce for educational use only.
