STRAND 1.0: FOUNDATION OF COMPUTER STUDIES

Sub Strand: 1.3 Input/Output (I/O) Devices

Specific Learning Outcomes

By the end of the sub-strand, the learner should be able to:

a) Describe the types of input and output devices used in computer systems,

b) examine the criteria for selecting input and output devices,

c) use input and output devices to perform tasks,

d) recognise the technological advancement of input and output devices.

Suggested Learning Experiences

The learner is guided to:

• discuss types of input devices (keying devices, pointing devices, scanning devices, voice input devices, touch screen, digitiser, digital cameras, quick response (QR) code, touch screens, resistive, speed sensors, weather sensors, microphones, drones, smart traffic lights),
• use print or digital resources to search for information on output devices (printers, monitors, speakers, LED, projectors, plotters, actuator roadside LED panels, variable message signs (VMS), digital signage),
• discuss methods that involve the use of input devices to enter data into a computer,
• Watch a video on how traffic and surveillance cameras record and monitor traffic flow.
• discuss methods used to output information from a computer,
• brainstorm factors to be considered when acquiring input and output devices,
• discuss the importance of using input and output devices in different areas (home devices, roads, cars, ATMs, Point of Sale Terminals, businesses, communication, and safety systems),
• Consult a resource person to demonstrate how input and output devices enhance road safety.
• create a quick response (QR) code and share information such as warnings and updates on road safety,
• Discuss the advantages and disadvantages of QR codes and traditional barcodes.
• scan a document and share with peers,
• visit a computer user environment and identify the input/output devices (traffic cameras, surveillance cameras, speed sensors, weather sensors, smart traffic lights),
• match input and output devices to their uses,
• Sensitise community members on how to reuse input/output devices.

Suggested Key Inquiry Question(s)

1. Why are input and output devices important in a computer?
2. What are the technological advancements in input/output devices?

Core Competencies to be Developed

Creativity and Imagination: The learner generates new ideas to create a quick response (QR) code and share information.

Learning to Learn: The learner shares experience on how to reuse input and output devices.

Values

Peace: The learner respects self and others while discussing the advantages and disadvantages of QR codes and traditional barcodes.

Unity: The learner collaborates with others to scan and share documents.

Pertinent and Contemporary Issues (PCIs)

Socio-economic and Environmental Issues: The learner observes safety in a computer user environment as they identify input/output devices.
