THedu'12 Scope

This workshop intends to gather the research communities for computer
Theorem proving (TP), Automated Theorem Proving (ATP), Interactive
Theorem Proving (ITP) as well as for Computer Algebra Systems (CAS)
and Dynamic Geometry Systems (DGS). The workshop tries 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

   * Declarative Languages for Problem Solution: education in applied
     sciences and in engineering is mainly concerned with problems,
     which involve operations on elementary objects to be transformed
     to an object representing a problem solution. Preconditions and
     postconditions of these operations can be used to 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

   * 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 inquiry-based learning from concrete to
     abstract --- and the knowledge's logical coherence supports such
     learning: for instance, the formula 2.pi 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 traceable 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, TP 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, this 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 series 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.
