THedu'11 Scope
--------------
This workshop intends to gather the research communities for Computer
Theorem proving (CTP), Automated Theorem Proving (ATP),  Interactive
Theorem Proving (ITP) as well as for Computer Algebra Systems (CAS) and
Dynamic Geometry Systems (DGS).
The goal of this union is to combine and focus systems of these areas to
enhance existing educational software as well as studying the design of
the next generation of mechanised mathematics assistants (MMA). Elements
for next-generation MMA's include:

  * Declarative Languages for Problem Solution: education in applied
sciences and in engineering is mainly concerned with problems, which are
understood as operations on elementary objects to be transformed to an
object representing a problem solution. Preconditions and postconditions
of these operations can be used describe the possible steps in the
problem space; thus, ATP-systems can be used to check if an operation
sequence given by the user does actually present a problem solution.
Such "Problem Solution Languages" encompass declarative proof languages
like Isabelle/Isar or Coq's Mathematical Proof Language, but also more
specialized forms such as, for example, geometric problem solution
languages that express a proof argument in Euklidian Geometry or
languages for graph theory.

  * Consistent Mathematical Content Representation:  libraries of
existing ITP-Systems, in particular those following the LCF-prover
paradigm, usually provide logically coherent and human readable
knowledge. In the leading provers, mathematical knowledge is covered to
an extent beyond most courses in applied sciences. However, the
potential of this mechanised knowledge for education is clearly not yet
recognised adequately: renewed pedagogy calls for enquiry-based learning
from concrete to abstract --- and the knowledge's logical coherence
supports such learning: for instance, the formula 2.Ï? depends on the
definition of reals and of multiplication; close to these definitions
are the laws like commutativity etc. However, the complexity of the
knowledge's tracable interrelations poses a challenge to usability design.

  * User-Guidance in Stepwise Problem Solving: Such guidance is
indispensable for independent learning, but costly to implement so far,
because so many special cases need to be coded by hand. However, CTP
technology makes automated generation of user-guidance reachable:
declarative languages as mentioned above, novel programming languages
combining computation and deduction, methods for automated construction
with ruler and compass from specifications, etc --- all these methods
'know how to solve a problem'; so, use the methods' knowledge to
generate user-guidance mechanically, is an appealing challenge for  ATP
and ITP, and probably for compiler construction!

In principle, mathematical software can be conceived as models of
mathematics: The challenge addressed by this workshop is to provide
appealing models for MMAs which are interactive and which explain
themselves such that interested students can independently learn by
inquiry and experimentation.
