DATA PROCESSING

Subject	Digital Technologies
Class	JSS 1 (Basic 7)
Term	Second Term
Week	3
Topic	Data Processing
Duration	80 Minutes (Double Period)

1. BEHAVIOURAL OBJECTIVES

By the end of the lesson, students should be able to:

1. Define data, information, and data processing.
2. Identify and explain the major stages of data processing.
3. Differentiate between manual and electronic data processing.
4. State at least four importance of data processing.
5. Give examples of data processing in schools, banks, businesses, and other organisations.
6. Calculate simple totals and averages from given data.

2. INSTRUCTIONAL / TEACHING AIDS

• Computer system or laptop.
• Calculator, where available.
• Whiteboard and markers.
• Paper, pens, and sample school registers.
• Sample examination scores and sales records.
• Spreadsheet software, if available.

3. PREVIOUS KNOWLEDGE / ENTRY BEHAVIOUR

Students are familiar with numbers, names, examination scores, and other facts collected in everyday life. They may have seen teachers calculate scores, shopkeepers add prices, or school officials arrange students' records.

The teacher asks students to mention examples of facts collected in school and explain how those facts can be arranged or used to obtain useful information.

4. PRESENTATION STEPS

STEP	TEACHER'S ACTIVITY	STUDENTS' ACTIVITY
Step 1: Introduction 10 minutes	The teacher presents examples of students' scores and prices of goods. The teacher asks how these figures can be used to calculate totals and obtain useful information.	Students observe the examples, answer questions, and describe situations in which they have seen data being collected or calculated.
Step 2: Meaning of Data, Information, and Data Processing 15 minutes	The teacher defines data, information, and data processing. Examples are given to show how raw facts become useful information after processing.	Students take notes, explain the key terms in their own words, and identify data and information from the examples provided.
Step 3: Stages of Data Processing 15 minutes	The teacher explains data collection, preparation, input, processing, output, and storage, using the preparation of examination results as an example.	Students list the stages, explain their functions, and arrange the stages in a logical sequence.
Step 4: Manual and Electronic Data Processing 15 minutes	The teacher compares manual processing with electronic processing, explaining their methods, speed, equipment, and examples.	Students identify examples of both methods and state differences between them.
Step 5: Importance and Practical Activity 15 minutes	The teacher explains the importance of data processing in education, banking, business, and healthcare. Students are guided to calculate the total and average of three examination scores.	Students state the benefits of data processing, calculate the given total and average, and explain how the results could be recorded or stored.
Step 6: Evaluation and Conclusion 10 minutes	The teacher asks oral questions, corrects misunderstandings, reviews the major concepts, and gives the assignment.	Students answer questions, summarise the lesson, and write down the assignment.

5. EVALUATION QUESTIONS

1. Define data, information, and data processing.
2. List and explain four stages of data processing.
3. State three differences between manual and electronic data processing.
4. Mention four areas where data processing is used.
5. State four reasons why data processing is important.
6. A student scores 12, 16, and 18 in three subjects. Calculate the total and average score.

6. ASSIGNMENT

1. Explain the meaning of data processing in your own words.
2. List the stages of data processing and explain any four.
3. Give three examples each of manual and electronic data processing.
4. State five importance of data processing in a school.
5. A shopkeeper records sales of ₦1,200, ₦800, and ₦500. Calculate the total sales and explain how the information can be stored for future use.

7. TEACHER'S REFLECTION

After the lesson, the teacher should reflect on the following:

• Were students able to explain data, information, and data processing?
• Could students identify the major stages of data processing?
• Were students able to differentiate between manual and electronic methods?
• Could students calculate simple totals and averages correctly?
• Which concepts require further explanation or practical demonstration?
