The BIG Idea Big Idea: Information and communication systems greatly impact our quality of life and are an essential component of business and industry that is rapidly expanding. © 2013 International Technology and Engineering Educators Association STEM  Center for Teaching and Learning™ Foundations of Technology

The Systems Model and Communication Information and Communication systems follow the systems model and require inputs, processes, outputs, and feedback. © 2013 International Technology and Engineering Educators Association STEM  Center for Teaching and Learning™ Foundations of Technology

The Systems Model Inputs – What goes into the system. (people, capital, materials, tools, energy, knowledge, and time). Process – All the activities that take place. (Designing, constructing, testing, tweeking, etc.) Output – The results of the system. (product, new knowledge, impacts) Feedback – Tells the system if it is working or not. © 2013 International Technology and Engineering Educators Association STEM  Center for Teaching and Learning™ Foundations of Technology

The Systems Model and Communication Example: Sending a text message © 2013 International Technology and Engineering Educators Association STEM  Center for Teaching and Learning™ Foundations of Technology Input: the desire to send a text message and preparation for it. Process: entering the information using a mobile phone and transmitting it. Output: the message is displayed Your message here Feedback: confirmation of the message

Information and communication systems can be further broken down into the: ELEMENTS OF COMMUNICATION - Parts Sender – the person or machine originating the communication Message – what is being communicated Channel – What the message is sent via Receiver – the device that collects the message Feedback - Working? Interference –Not working? © 2013 International Technology and Engineering Educators Association STEM  Center for Teaching and Learning™ Foundations of Technology

Information and communication systems can be further broken down into the: PROCESSES OF COMMUNICATION Encoding – Puts message into a transmittable form Transmitting – Sending message over path Receiving – downloads the message Decoder – Changes the message back into a form that we can understand. Storage – the device that stores the communication Retrieval – the device that retrieves the communication on command © 2013 International Technology and Engineering Educators Association STEM  Center for Teaching and Learning™ Foundations of Technology

Communication Nonverbal communication is the process of communicating without using words, generally using visual cues between people. Kinesics – the study of communication through gesture, posture, and movement Haptics – the study of communication through touching © 2013 International Technology and Engineering Educators Association STEM  Center for Teaching and Learning™ Foundations of Technology
