Instructional Procedures and Content Notes
Silent Reading (7 minutes) – Slide is automatically timed
Write Objectives (5 minutes) – Students write daily objectives in their notebooks. Leaving enough room to write the
answers to the objectives at the end of class / Slide is automatically timed (Song may play to tie into the objectives)
Chapter PowerPoint (35 minutes, approximately can go much longer or shorter)
Teacher conducts interactive lecture with a PowerPoint slideshow while students take fast notes and participate in higher
order questioning, and small group activities. 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 website
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 website
Modifications to meet student needs (IEP, ILP, ELL and Special Needs)
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.
Modifications to meet student needs (Enrichment)
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.

The Technological System

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

Permission granted to reproduce for educational use only.
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.

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.

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

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.

Types of Control Systems
• Two major types of control systems used:
– Open-loop control and closed-loop control.
• Open-loop systems use no feedback.
• More systems use closed-loop systems, which means
these systems use feedback.
• Technology systems, such as manufacturing, use market
research, quality control, inventory control, process
control, material resource control, and wage control.
© Goodheart-Willcox Co., Inc.
Permission granted to reproduce for educational use only.
Components of Control Systems
• Monitoring devices include:
– Mechanical sensors, thermal sensors,
optical sensors, electrical or electronic
sensors, and magnetic
(electromagnetic) sensors.
• Data-comparing devices like:
– Analytical systems and judgmental
systems.
• Adjusting devices are controllers.
© Goodheart-Willcox Co., Inc.
Permission granted to reproduce for educational use only.
Adjusting Devices
• Four adjusting devices:
– Mechanical controllers: cams, levers, and other
linkages.
– Electromechanical controllers: electromagnetic
coils and forces to move linkages.
– Electrical and electronic controllers: switches,
transistors, and integrated circuits.
– Fluidic controllers: fluids and air.

Permission granted to reproduce for educational use only.
The Operation of Control Systems
• Technological control systems can be
classified as:
– Manual control systems like systems that
pilots would use.
– Automatic control systems like
thermostats in heating systems.
