3. mention the uses of data processing.

ENTRY BEHAVIOUR

The pupils can define data as information.

INSTRUCTIONAL MATERIALS

The teacher will teach the lesson with the aid of: Functional computer systems and other devices.

METHOD OF TEACHING

Choose a suitable and appropriate methods for the lessons.

Note – Irrespective of choosing methods of teaching, always introduce an activities that will arouse pupil’s interest or lead them to the lessons.

CONTENT OF THE LESSON 

LESSON 1 – INTRODUCTION 

Data processing is the process that convert data into information by the computer.

The process is automated that runs on computers and other information systems.

Data processing coverts raw data collected, filtered, sorted, processed, analyzed, stored, and then produced usable and desired form.

The types of data processing are Batch Processing, Real – time Processing, Online Processing, Multiprocessing and Time-sharing

METHODS OF COLLECTING DATA

There are 3 main data processing methods:

1. Manual

2. Mechanical

3. Electronic

1. MANUAL DATA PROCESSING 

Manual data processing is the method of process of collecting, filtering, sorting, processing, analyzing, storing and producing data by human without the use any electronic device or automation software.

It is a low cost method to data processing and requires little or no tools.

The human errors are high and consume lots of time.

2. MECHANICAL DATA PROCESSING 

Mechanical data processing is the method of process of collecting, filtering, sorting, processing, analyzing, storing and producing data using simple devices and machines such as calculators, typewriters, printing press, etc.

It produces less errors than manual and save little more time.

3. ELECTRONIC DATA PROCESSING 

Electronic data processing is the method of processing data using modern technology, software and programs.

This method is the most fastest, reliable, accurate and very expensive.

 

LESSON 2 – USES OF DATA PROCESSING 

The uses of data processing are as follows:

1. It is used for large amounts of data such payroll.

2. It used for small amounts of data such such money withdrawn from ATM.

3. It is used for scanning data such as barcode.

4. It is used to process large data at a time.

5. It is used for forecasting weather.

6. It is used for controlling air traffic.

7. It is used for sorting and arranging data.

8. It is used for reducing large data to its main points.

9. It used for compiling multi data.

10. It is used for summarizing computed data.

11. It is used for classifying data into different categories.

12. It is used for collecting, organizing, analysing, interpreting and presenting data.

13. It used for validating data correctly.

LESSON 3 – REVISION AND WEEKLY ASSESSMENT 

As stated in performance objectives or lesson evaluation. 

PRESENTATION

To deliver the lesson, the teacher adopts the following steps:

1. To introduce the lesson, the teacher revises the previous lesson. Based on this, he/she asks the pupils some questions;

2. Teacher organizes pupils in groups or pairs depending on the size of the class.

3. Teacher gives each of the group or pair mental sum.

4. Teacher also gives the same mental sum with simple device such calculator.

Pupil’s Activities – Perform mental sums with or without any simple device.

5. Teacher asks pupils to compare the result and differentiate between the sums.

Pupil’s Activities – Differentiate between manual and electronic data processing.

6. Teacher listen to the pupils and uses their responses to introduce the lesson.

Pupil’s Activities – Pay attention to the lesson introduction to understand the concept of data processing.

7. Teacher leads a discussion on methods of data processing such manual, mechanical and electrical data processing.

Pupil’s Activities – Uses mental sum with and without simple device to differentiate between different methods of data processing.

8. Teacher uses types of data processing as discussed in previous class to introduce and discuss uses of data processing.

Pupil’s Activities – Participate actively in the class discussion to analyze the important use of data processing in their communities.

9. Teacher summarizes the lesson on the board with appropriate lesson evaluation.

Pupil’s Activities – Participate actively in the summary of the lesson by responding correctly to the lesson evaluation and write as instructed.

CONCLUSION

To conclude the lesson for the week, the teacher revises the entire lesson and links it to the following week’s lesson.

NEXT LESSON

Revision and Second Term Examination – Second Term Examination Computer Studies Primary 4 (Basic 4)

LESSON EVALUATION 

Teacher asks pupils to:

1. explain the meaning of data processing.

2. state 3 methods to data processing.

3. explain the following:

• Manual data processing

• Mechanical data processing

• Electronic data processing

4. differentiate between manual, mechanical and electronic data processing.
