The tremendous growth of Information Technology during the past two decades has indeed set the educational planners thinking. The thoughts have mainly concentrated in the following areas:

Forum for Computer Education in SchoolsIn association with Indiatimes

Information Technology in schools in the new millenniumBy A N Warhadpande

Present Environment

• Using technology in planning of lessons.

• Nature of class rooms tomorrow.

• Integrating technology with school education.

• Use of Multimedia and Internet to benefit learning.

• Teachers becoming facilitators for learning.

• Interactive learning where the teachers also learn from children in addition to children learning from their peers.

• Sharing of lessons, assignments and evaluation of performance through the Internet.

• Coping up with curriculum while learning to use technology.

• Evaluation philosophies and techniques.

A country or an individual cannot become great just by copying someone else.

Should we ape?

"I cannot say that everything is wrong with the Indian Education system, if that were the case we would not have seen so many top professionals who are Indians in the developed countries.“

"I cannot say that everything is wrong with the Indian Education system, if that were the case we would not have seen so many top professionals who are Indians in the developed countries.“

Dr. Karan Singh

To progress, it is absolutely necessary to:

examine the environment,

In short, every project needs to be individually studied. We certainly have to take advantage of the facilities provided by technology in all walks of life including education. In education, we are dealing with children and we do not immediately see what good or bad we are doing for them, it is

revealed several years later.

the state of technology, availability and quality of both material and human resources.

6

A lot has been said, written and discussed by various specialists in various forums on these topics.

Recent Discussions

After being exposed to the various thoughts on the subject one gets totally lost!

7

and Parents…

One hears parents say very proudly "My child is only three years old and spends hours with the computer, hearing stories, seeing pictures and interacting with the machine".

Some people have already started saying, "If Internet is not brought to school, children will have to interrupt their learning for coming to school".

8

Repercussions

With a little reflection, the questions that dominates are:

"Have we seriously thought about what a child should be exposed to in say 10 to 12 years of schooling?"

What about getting used to living in a society?

Can we human beings spend our lives with a machine for company?

Will we be happy to get help and assistance from machines only instead of advice and guidance from parents, elders and even peers?

Will the machines be more satisfying friends than live human beings?

9

Some more…

It should be of great concern to see that so much thought is going into how teaching and learning should take place and nobody talks about what should be taught or learnt.

• On the other hand we complain that the use of technology by children do not learn the basic concepts.

• They should have a facility to get answers to their questions as and when questions occur to their mind. So!So! Every child should have a multi -media system with an Internet access at all times.

• We talk about using technology to facilitate all our work. Children should carry their computers to school and back, instead of having a load of books and notebooks.

IntroductionWorkbooks   In Microsoft Excel, a workbook is the file in which you work and store your data. Because each workbook can contain many sheets, you can organize various kinds of related information in a single file. By default a workbook contains 3 worksheets.

49

Introduction

Worksheets   Use worksheets to list and analyze data. You can enter and edit data on several worksheets simultaneously and perform calculations based on data from multiple worksheets.

Sheet tabs   The names of the sheets appear on tabs at the bottom of the workbook window. To move from sheet to sheet, click the sheet tabs.

Active/Selected cellA cell is the intersection of a row and column. The cell that is selected by clicking or using the arrow keys is the insertion point.

50

Introduction

A block of cells is selected by using arrow keys while holding down the shift key or simply clicking and dragging the mouse across a range of adjacent cells

Chapter – 4 (Beginning C++)

Discussion Outline• Introduction • Brief History of C++• Development Cycle• C++ Character Set• Data Types in C++• Identifiers and Keywords• Structure of a C++ Program• Variables• Constants: Literals• Comments• Preprocessor• Basic Input/Output• Formatted Output

Introduction

• Languages evolve to solve specific problems• The Object Oriented approach evolved similarly

providing techniques for managing enormous complexity reuse of software components defining data coupled with related tasks

• OOP treats data and the procedures that act upon the data as a single “object”

• The object is a self contained entity with an identity and certain characteristics of its own

• Some OOP languages are SmallTalk, Java, C++, Ada etc.

• C++ is a superset of the language “C” – it inherits all the features of C and adds a whole lot of capabilities to it

71

Features of OOP

• Simple, easy to maintain, reusable programs known as objects

• Binds code and data together creating a more powerful unit encompassing all details of a process or a task

• Such modules or objects can be dedicated to perform specific tasks

72

A Sample ProgramC++ is a powerful general-purpose programming language. It can be used to create small programs or large applications.

#include <iostream.h> int main() { cout<<"HEY, you, I'm alive! Oh, and Hello World!"; return 0; }

#include <iostream.h> int main() { cout<<"HEY, you, I'm alive! Oh, and Hello World!"; return 0; }

Let's look at the elements of the program.

#include: A preprocessor directive that tells the compiler to put code from the header file iostream.h into our program. By including header files, you an gain access to many different functions. For example, the cout function requires iostream.h.

int main(): This line tells the compiler that there is a function named main, and that the function returns an integer, hence int.

Braces ({ and }) signal the beginning and end of functions and other code blocks.

cout Function: The next line of the program may seem strange. If you have programmed in another language, you might expect that print would be the function used to display text. In C++, however, the cout function is used to display text.

Insertion operators: The <;<; symbols, are known as insertion operators. The quotes tell the compiler that you want to output the literal string as-is.

Terminator: The semicolon is added onto the end of all function calls in C++; the semicolon later shows up when you declare variables.

73

Class

• A set, collection, group, or configuration containing members regarded as having certain attributes or traits in common; a kind or category.

• Provides the way to create User Defined data type

• A Class combines attributes (behavior) of an Object and the operations (functions) performed on the attributes of that object

• An Object is an Instance of a Class

74

Abstraction

• Provides facility to/for:create user defined data typeencapsulationdata security

• Abstraction handles the complexities of an object• Example:

Driver changes gears while driving. The task is performed but the actual process of gears changing is hidden from him.
