JSS 3 First Term

LEARNING OBJECTIVES: BY THE END OF THE LESSON PUPILS SHOULD BE ABLE TO:

Cognitive	i. Revise every topic of the First Term. ii. Practise questions on networks, number systems and programming. iii. Identify and settle weak areas before the examination. iv. Plan the final week of revision.
Affective	i. Appreciate the value of Revision in school, at home and in the community. ii. Show willingness to use digital tools carefully, safely and responsibly.
Psychomotor	i. Write the four network types and one example of each from memory. ii. Convert 1101 to decimal and 13 to binary without looking at your notes. iii. Draw the truth tables for AND, OR and NOT from memory. iv. Write the algorithm for a simple everyday task in five steps.

Rationale: A network is two or more devices connected so they can share resources. Understanding review of Networks and the Internet, review of Number Systems and Data Representation, review of Logic, Algorithms and Programming, answering Examination Questions helps learners use digital technology confidently, safely and responsibly.

Pre-requisite Knowledge: In Week 10, learners studied Electronic Mail and Presentation Software, including parts of an Email Message, how Email Travels, composing and Sending. The knowledge from that week is used again in this lesson.

Learning Material/Teaching Aid: Whiteboard, markers, computer or laptop where available, printed notes and charts on Revision, practical task sheets, learners' notebooks and pens.

Reference Materials: Digital Technology for Junior Secondary Schools (JSS 3); NERDC Digital Technology Curriculum; Digital Technology JSS 3 First Term Notes (Week 11); First Term examination and Continuous Assessment question papers.

LESSON DEVELOPMENT

Stage/Step (Time)	Teacher's Activities	Student's Activities	Learning Points
Introduction 5 MINUTES	Welcomes learners, revises Week 10 (Electronic Mail and Presentation Software) with two quick oral questions, and asks what they already know about Revision. Elicits responses and writes the topic on the board.	Recall the previous lesson and share what they already know about Revision.	Connecting prior knowledge to Revision.
Step 1 6 MINUTES	Covers Review of Networks and the Internet: A network is two or more devices connected so they can share resources. Networks are named by the area they cover: a PAN around one person, a LAN in one building, a MAN across a city and a WAN across a country or the world. The internet is the largest WAN.	Listen, take notes and answer oral questions on "Review of Networks and the Internet".	Understanding: Review of Networks and the Internet.
Step 2 6 MINUTES	Covers Review of Number Systems and Data Representation: A number system is built on a base. The decimal system is base 10, the binary system is base 2, the octal system is base 8 and the hexadecimal system is base 16. The value of a digit depends on its place value.	Copy the key points, give examples from school and everyday life, and ask questions on "Review of Number Systems and Data Representation".	Understanding: Review of Number Systems and Data Representation.
Step 3 6 MINUTES	Covers Review of Logic, Algorithms and Programming: A logic gate takes one or more bits and gives one bit. The AND gate needs both inputs to be 1, the OR gate needs at least one, and the NOT gate flips its single input. Every gate can be shown in a truth table.	Discuss in pairs, then report one point on "Review of Logic, Algorithms and Programming" to the class.	Understanding: Review of Logic, Algorithms and Programming.
Step 4 6 MINUTES	Covers Answering Examination Questions: Objective questions reward accuracy, so read every option before choosing. Short answer questions reward precision, so give exactly what is asked. In a difference question write both parts in the order asked.	Respond to questions, complete the examples on the board and note down "Answering Examination Questions".	Understanding: Answering Examination Questions.
Practical Work 6 MINUTES	Guides learners through the practical work: (i) Write the four network types and one example of each from memory. (ii) Convert 1101 to decimal and 13 to binary without looking at your notes. (iii) Draw the truth tables for AND, OR and NOT from memory. Moves round the class to check progress and correct unsafe or careless use.	Carry out the practical tasks individually or in pairs and record what they did in their notebooks.	Applying the lesson through hands-on practice.
Evaluation 3 MINUTES	Asks learners to: i. Revise every topic of the First Term. ii. Practise questions on networks, number systems and programming. iii. Identify and settle weak areas before the examination. iv. Plan the final week of revision.	Respond verbally and in writing to the evaluation questions.	Assessment and consolidation of the lesson content.
Conclusion 2 MINUTES	Recaps the main points: review of Networks and the Internet, review of Number Systems and Data Representation, review of Logic, Algorithms and Programming, answering Examination Questions. Links them to the assignment and previews Week 12: Examination.	Listen, ask questions and copy the assignment.	Reinforcement of key concepts and a preview of the next lesson.

Assignment: i. (a) Define Digital Citizenship and state three (3) qualities of a good digital citizen. (b) Explain the term Digital Footprint and how students can maintain a positive online reputation. (c) Mention two (2) dangers of unsafe online behaviors (e.g., cyberbullying or sharing personal data). ii. A pupil connects a Bluetooth headset to a phone, a school laboratory has 30 computers sharing one printer, a university links campuses in different parts of Abuja, and the whole world is linked together. Classify each of these four situations as a PAN, LAN, MAN or WAN, and give the meaning of each term.
