The Unit Big Idea The designed world is the product of a design process, which provides ways to turn resources - materials, tools and machines, people, information, energy, capital, and time - into products and services. © 2011 International Technology and Engineering Educators Association, STEMCenter for Teaching and Learning™ Foundations of Technology ©International Technology Education Association Center to Advance the Teaching of Technology & Science Engineering byDesign™
The Lesson Big Idea Information and communication systems greatly impact our quality of life. © 2011 International Technology and Engineering Educators Association, STEMCenter for Teaching and Learning™ Foundations of Technology ©International Technology Education Association Center to Advance the Teaching of Technology & Science Engineering byDesign™
Systems Model Information and Communication systems follow the systems model and require inputs, processes, outputs and feedback. Example: Text messaging Inputs: a phone, a person operating the phone, cell phone service, etc. Process: transmitting the message using phone, landlines and/or satellite, phone Output: message sent Feedback: undeliverable message or confirmation of message sent © 2011 International Technology and Engineering Educators Association, STEMCenter for Teaching and Learning™ Foundations of Technology ©International Technology Education Association Center to Advance the Teaching of Technology & Science Engineering byDesign™

Email Example Source: Person typing the message Encoder: CPU used to translate the keyboard strokes to programming language Transmitter: Wireless connection, modem, phone line Receiver: router on other computer © 2011 International Technology and Engineering Educators Association, STEMCenter for Teaching and Learning™ Foundations of Technology ©International Technology Education Association Center to Advance the Teaching of Technology & Science Engineering byDesign™
Email Example Decoder: CPU used to translate binary code to software application Storage: Inbox, hard drive, server Retrieval: Software application which pulls up email, such as Outlook, gmail, etc. Destination: Other person reads the email © 2011 International Technology and Engineering Educators Association, STEMCenter for Teaching and Learning™ Foundations of Technology ©International Technology Education Association Center to Advance the Teaching of Technology & Science Engineering byDesign™
Reflection Can you think of other I&C systems and identify the inputs, process, output and feedback? Can you identify the source, encoder, transmitter, receiver, decoder , storage, retrieval , and destination? © 2011 International Technology and Engineering Educators Association, STEMCenter for Teaching and Learning™ Foundations of Technology ©International Technology Education Association Center to Advance the Teaching of Technology & Science Engineering byDesign™
