Teacher guide — Lesson 1 | Dalswin Institute

Preparation

Before the class starts

Open the lesson site on the projector and test the slides, quiz and practice activities.
Bring at least three real devices if possible: a desktop or laptop, a tablet or phone, and a small embedded device (calculator, remote, smart card).
Print the assignment brief and rubric for learners without devices, or show them where to print.
Have a backup plan for no internet: the reading and slides can be printed from the browser before class.
Prepare a simple cashier or attendance example for the information-cycle demonstration.
Check that learners can open a browser and reach the practice page; pair those who share a device.

Run sheet

150-minute lesson plan

Time	Mode	Instructor	Learners
0–30 min	Theory	Define a computer, walk through the information cycle, give workplace examples and introduce the computer types. Ask frequent questions.	Take notes, answer questions, copy the key terms.
30–60 min	Demonstration	Tour the real devices. Trace one task through input, processing, output and storage. Show where the processor, memory and storage sit.	Observe, identify the four jobs, ask questions.
60–120 min	Guided practice	Guide the reading, then the slides, then the three practice activities. Circulate and correct misconceptions.	Read, follow the slides and complete the practice lab, individually or in pairs.
120–140 min	Independent	Set the quiz and start the assignment. Monitor scores; note learners below 6/10 for follow-up.	Complete the quiz, then begin the computer hunt and recommendations.
140–150 min	Review	Discuss quiz answers, correct the most common errors, preview hardware and software for Day 2.	Ask questions, correct notes, note homework.

Answer keys

Quiz and practice answers

Quiz — 10 questions

B — accepts data, processes with instructions, produces information.
A — typing a price is input.
C — a printer presents output.
B — a laptop combines screen, keyboard, battery and computer.
C — a server provides shared records.
A — a washing-machine control unit is embedded.
True — a smartphone performs all four jobs.
A — a workstation is built for demanding professional work.
B — a laptop suits a travelling sales officer.
B — computer skills support accuracy, organisation and communication.

Practice lab

Computer or not: smartphone C, paper notebook N, laptop C, bicycle N, ATM C, ruler N, tablet C, candle N. (C = computer, N = not.)
Device match: receptionist → desktop; field officer → laptop; café counter → tablet; clinic records → server; commuter → smartphone; car engine → embedded system.
Cycle: typing → input; spelling check → processing; monitor → output; saving → storage; mouse click → input; Excel total → processing; speakers → output; flash drive → storage.

Assignment — model recommendations

Accept other choices when the learner gives sound reasons. The reasoning matters more than the exact device.

Receptionist → desktop with printer and surge protector. Fixed desk, large screen, comfortable keyboard, best value; a laptop would waste money on portability that is never used.
Field sales officer → laptop with a carry bag and mobile data. Portable, full keyboard, runs catalogues and email; battery life matters.
Accountant → desktop or workstation with a second monitor and external backup. Large spreadsheets, dual screens, reliable power and easy repair.
Managing director → lightweight laptop or tablet with a carry case and cloud storage. Travels, presents and reads email; battery life and weight matter more than raw power.

Watch for these

Common misconceptions

“The monitor is the computer.”The monitor is an output device. The processor, memory and storage may be in a case, inside the screen, or in a phone.

“A phone is not a real computer.”A smartphone performs all four jobs and runs programs. Its limits are screen size and typing, not computing ability.

“The most expensive device is best.”Fit matters. A tablet beats a workstation at a café counter; a desktop beats a laptop for a receptionist who never moves.

“A server is just a fast desktop.”A server is defined by its role — providing shared files and services — and needs backups, security and administration.

“Storage and memory are the same.”Storage keeps files when the power is off. Memory (RAM) is temporary working space used while programs run. Keep this distinction light on Day 1; it returns in Day 2.

“Embedded computers are not real computers.”They accept input from sensors, process it and produce output. They are dedicated to one job, which is why they look different.

Support every learner

Differentiation and assessment

Learners without a device

Pair them with a device user for the practice lab. Print the reading and assignment brief. The computer hunt can be completed on paper from observation; the memo may be handwritten and still earns full marks for content and structure.

Advanced learners

Ask them to compare two devices for the same role or calculate a simple cost comparison. Challenge them to find three embedded computers in the room and explain the input and output of each.

Language support

Pre-teach six terms: input, processing, output, storage, hardware, software. Use the glossary and ask learners to give one local example for each. Allow answers in a familiar language first, then translate the key term.

Assessment link

The quiz is formative. The 30-mark assignment feeds the Computer Fundamentals component (10% of the programme). Day 5 adds the practical folder-and-document assessment for Week 1.

Homework: finish the reading, practice and quiz; complete and submit the memo before Day 2.
