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 Euclidian 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.
