Instructional Materials

The teacher will teach this lesson with the aid of:

A computer system (or laptop)
Keyboard chart or physical keyboard
Charts showing data and information examples
Prepared class data set (scores, names, numbers)
Whiteboard/marker

Rationale for the Lesson

This lesson helps pupils understand the clear difference between raw facts and meaningful results. It also enables pupils to see how correct keyboard inputs can produce useful information for daily school and business tasks.

Prerequisite/Previous Knowledge

Pupils have basic knowledge of data and information from the previous lesson and have seen a computer keyboard and simple typed text on a screen.

Lesson Content/Board Summary

Data and Information

Differences Between Data and Information

The following are differences between data and information:

Data are raw facts and figures, while information is processed data with meaning.
Data may be unorganized, while information is organized and easy to understand.
Data is the input, while information is the output after processing.
Data alone may not help decision making, while information supports decision making.
Data can contain errors or noise, while information is usually checked and summarized.

Examples of Data and Information

The following are examples of data and the information obtained from them:

Data: 40, 55, 60, 75, 90; Information: Highest score is 90, lowest score is 40, average score can be calculated.
Data: Daily sales (₦5,000, ₦7,500, ₦6,000); Information: Total sales for three days is ₦18,500.
Data: Attendance numbers for a week; Information: Total attendance and number of absentees for the week.
Data: Names and ages of pupils; Information: List of pupils within a given age range.

Keyboard Arrangement as Data

The keyboard contains letters, numbers, and symbols arranged in keys. These keys represent data items because they are raw inputs that must be pressed and processed before any meaning appears on the screen.

The following are examples of keyboard data items:

Alphabet keys: A to Z
Number keys: 0 to 9
Symbol keys: +, -, /, ?, @
Space bar and enter key used to separate and arrange typed data

Typing Alphabets and Numbers to Produce Information

Typing is the act of entering data (letters and numbers) into the computer through the keyboard. When the typed data is arranged to form meaningful words, sentences, or results, it becomes information.

The following show how typed data becomes information:

Data typed: C O M P U T E R; Information: The word “COMPUTER”.
Data typed: 2 0 2 6; Information: The number “2026” used as a year.
Data typed: 5 0 + 2 0; Information: The expression “50 + 20” which can be processed to get 70.
Data typed: A, B, C, 1, 2, 3; Information: A meaningful code or password when properly arranged.

Teaching Methods/Instructional Techniques

Discussion, Lecture, Demonstration, Question and Answer, Visual Aids

Instructional Procedures

Step 1: Introduction

Time: 5 minutes
Teaching Skill: Set Induction
Teacher’s Activity: The teacher writes random letters and numbers on the board and asks pupils to describe them as raw facts. The teacher asks pupils what happens when the letters are arranged into a word and introduces the topic for the day.
Pupils’ Activity: Pupils respond, identify the items as raw facts, and suggest words that can be formed from letters.
Learning Point: Raw inputs are data, and meaning comes after arranging or processing.

Step 2: Revision of Key Ideas

Time: 6 minutes
Teaching Skill: Questioning
Teacher’s Activity: The teacher asks pupils to recall basic meanings of data and information and guides a short recap using examples from school records.
Pupils’ Activity: Pupils answer questions and give simple examples of data and information.
Learning Point: Data and information are related, but they are not the same.

Step 3: Differences Between Data and Information

Time: 8 minutes
Teaching Skill: Explanation
Teacher’s Activity: The teacher presents a clear list of differences between data and information and writes key points on the board.
Pupils’ Activity: Pupils copy notes and contribute additional differences.
Learning Point: Data is input and information is meaningful output.

Step 4: Examples of Data and Information

Time: 7 minutes
Teaching Skill: Illustration
Teacher’s Activity: The teacher provides sample data sets (scores, sales) and guides pupils to state the information obtained (highest, total, summary).
Pupils’ Activity: Pupils suggest information derived from each data set and copy the examples.
Learning Point: Information is obtained when data is summarized or interpreted.

Step 5: Demonstration Using Keyboard Arrangement as Data

Time: 8 minutes
Teaching Skill: Demonstration
Teacher’s Activity: The teacher displays the keyboard and points out letters, numbers, and symbols as data items. The teacher explains that keys are raw inputs until they are pressed and processed by the computer.
Pupils’ Activity: Pupils observe the keyboard, identify letter and number keys, and classify them as data items.
Learning Point: Keyboard keys provide data input for the computer.

Step 6: Practical Activity (Typing to Produce Information)

Time: 6 minutes
Teaching Skill: Practical Skill Development
Teacher’s Activity: The teacher guides pupils to type given alphabets and numbers to form meaningful words and simple numeric expressions. The teacher checks correctness and explains how meaning appears as information on the screen.
Pupils’ Activity: Pupils type assigned letters and numbers, form words and numbers, and read the output on the screen.
Learning Point: Typed letters and numbers become information when they form meaningful output.

Step 7: Evaluation/Review

Time: 5 minutes

Teaching Skill: Questioning/Assessment

Teacher’s Activity: The teacher evaluates the learning by asking the following questions:

State four differences between data and information.
Give two examples of data and state the information obtained from each.
Explain why keyboard letters and numbers are regarded as data.
Explain how typing alphabets and numbers can produce information.

Pupils’ Activity: Pupils answer orally and in writing.

Learning Point: Pupils demonstrate understanding of the lesson.

Step 8: Conclusion

Time: 0 minutes
Teaching Skill: Summarization
Teacher’s Activity: The teacher summarizes the key differences, gives final examples, and emphasizes correct input during typing. Assignment: write five examples of data from daily life and state the information that can be obtained from each; type one meaningful sentence and one four-digit number in the computer lab.
Pupils’ Activity: Pupils copy the summary points and assignment.
Learning Point: Data becomes information when it is arranged, processed, and given meaning.

Lesson Keywords

Data – Raw facts and figures used as input.
Information – Processed data that is meaningful and useful.
Input – Data entered into the computer through devices like the keyboard.
Keyboard – An input device used to enter letters, numbers, and symbols as data.
Processing – Converting data into a useful form to produce information.

Differentiation

Pupils who need support will use guided examples and teacher-provided word lists for typing, while advanced pupils will create their own data sets and generate at least three information statements from each.

Note for teachers using this lesson plan

Emphasize examinable differences between data and information and ensure pupils can support answers with clear examples. During the practical activity, focus on correct key identification and meaningful outputs to connect keyboard inputs to real information.
