<str<strong>on</strong>g>The</str<strong>on</strong>g> Xmath calculator is further developed. A<br />

sophisticated <strong>on</strong>line calculator has been missing<br />

in c<strong>on</strong>necti<strong>on</strong> with mathematical and scientific e-<br />

learning and will increase the performance/price<br />

rate of the system.<br />

3. MODULES AND OBJECTS<br />

A module is a collecti<strong>on</strong> of objects- a menu<br />

card of objects- which are grouped under a<br />

mathematical topic. Metadata assigned to the<br />

object may suggest to the publisher the order in<br />

which these objects can be organized. As an<br />

example the main topic level could be Calculus,<br />

next level Functi<strong>on</strong>s and then the module<br />

C<strong>on</strong>tinuity divided into different objects for<br />

download.<br />

A module may c<strong>on</strong>tain an introducti<strong>on</strong> object,<br />

theory objects, examples objects, exercises<br />

objects, assessments objects, applicati<strong>on</strong>s<br />

objects, graphics objects, animati<strong>on</strong>s objects and<br />

student projects objects. Not all modules will<br />

necessary include all the different kinds of<br />

objects. <str<strong>on</strong>g>The</str<strong>on</strong>g> objects in a module may be<br />

downloaded independently of each other but the<br />

publisher will have access to informati<strong>on</strong> about<br />

the c<strong>on</strong>necti<strong>on</strong> between the objects and how to<br />

organize them. However if a publisher <strong>on</strong>ly needs<br />

the animati<strong>on</strong> object, say, he will then download<br />

<strong>on</strong>ly this object.<br />

(similarly as for cybernetics). Our modules called<br />

“Discovering Mathematics” do not bel<strong>on</strong>g to any<br />

specific field of mathematics; they are built<br />

primarily from the “Problems point View”.<br />

Mathematical problems, mostly drawn from<br />

calculus, are presented in a form which enables<br />

to create, in the process of their soluti<strong>on</strong>, an<br />

interc<strong>on</strong>nected network of new problems.<br />

To help the user to develop ability in solving<br />

problems the network then helps to find easier<br />

problems which she can solve if she is not able<br />

find a soluti<strong>on</strong> of the first problem or more<br />

complicated <strong>on</strong>es of the same character.<br />

5. MATHEMATICAL DICTIONARY<br />

<str<strong>on</strong>g>The</str<strong>on</strong>g> interface to the repository of modules<br />

(dMathArchive) is intended to be easy to use and<br />

a selected mathematical item may be search for<br />

to find the definiti<strong>on</strong> and an introducti<strong>on</strong> to the<br />

item. This will work like a mathematical dicti<strong>on</strong>ary<br />

with a wide range of items being present.<br />

Searching for “Eigenvalue” the definiti<strong>on</strong> and an<br />

introducti<strong>on</strong> to the topic “Eigenvalue” will show<br />

up.<br />

6. EVOLUTIONARY SYSTEM<br />

In the design of the dMathArchive the c<strong>on</strong>cept<br />

of “Evoluti<strong>on</strong>ary user c<strong>on</strong>trolled development”<br />

(EUCD) will be important. <str<strong>on</strong>g>The</str<strong>on</strong>g> dMath project will<br />

implement this c<strong>on</strong>cept by letting<br />

users/publishers develop their own objects for<br />

upload to the database repository or modify<br />

existing modules/objects. This will do the archive<br />

“c<strong>on</strong>tinuously growing” and give it an “agile<br />

development ” with focus <strong>on</strong> changes. Of course<br />

the modules and objects have to be reviewed by<br />

the editorial board of the archive.<br />

<str<strong>on</strong>g>The</str<strong>on</strong>g> same philosophy may be used for<br />

developing software packages for the Xmath<br />

Calculator.<br />

In the project modules in Number <str<strong>on</strong>g>The</str<strong>on</strong>g>ory,<br />

Calculus, Geometry, Differential Equati<strong>on</strong>s,<br />

Linear Algebra, Statistics and Probability,<br />

Numerical Methods, Interdisciplinary<br />

Mathematics and Fourier Series will be<br />

developed.<br />

4. INTERDISCIPLINARY MATHEMATICS<br />

Some of the modules require a special<br />

attenti<strong>on</strong>. <str<strong>on</strong>g>The</str<strong>on</strong>g> project is highly Multidisciplinary<br />

and Interdisciplinary and will develop modules in<br />

interdisciplinary mathematics [24]. Our aim is not<br />

to define what interdisciplinary mathematics is<br />
