Teaching mathematics in high school

Ralph Back Tapio Salakoski

Structured derivations in high schoolStructured derivations:Based on Dijkstras calculational style for proofsExtended to complete logical system based on sequent calculus (Back and von Wright: Refinement calculus, Springer 1998)Validated in Kupittaa high school pilot study3 year study (test group using structured derivations, control group using standard approach). All courses in high school curriculum coveredTest group clearly and consistently outperformed control groupPilot projects in a number of other high schools schoolsSupported by large course development and teacher training grantNew book: Mathematics with a little bit of logic Back and von WrightPresents basic approach as a high school course, lots of examples

Structured derivations exampleSolve equation |x-1|+|2x-y|=0

|x-1|+|2x-y|=0{property of absolute values}x-1=0 2x-y=0{add 1 to both sides of left equation}x=1 2x-y=0{simplify right conjunct}[x=1]2x-y=0{substitute x=1 by assumption}2-y=0{solve}y=2x=1 y=2motivate each step, on separate linenested derivationlogical notation in derivationassumptions have scopecollapsabel outlinesPublish on web

Invariant based programming

Ralph Back

Invariant based programmingConstructing programs and correctness proofs togetherBased on early work by Back and early TR by John ReynoldsStart by formulating the invariants of the system, then transitions between invariants, and then verify correctness of transitionsFormal methods lightEasy to learn, easy to use in practiceHave carried out a number of sessions teaching both novices and experienced programmers how to construct verified programsNow teaching approach to first year CS students at bo AkademiSocos environment provides computer support for methodDrawing diagrams, proving verification conditions automatically, generating executable code, testing and debugging

Nested invariant diagramsA: array 1..n of integer; Permutation(A,A0); 1 = A[k]i: integer; 1

Distributed Systems Design

Kaisa Sere, Marina Walden, Elena Troubitsyna

System approach - from theory to practiceSystem approachA system or a computer-based product is first modeled as one entity on a very abstract level. Thereafter, detail is introduced into the model in a systematic manner (e.g. using patterns).When the model is detailed enough it is decomposed into meaningful parts or sub-models, e.g. environment, hardware and software. Dependability: correctness (fault avoidance) , fault toleranceFormalisms: Action systems, B Method, Event BThe approach gives structure to the design of complex distributed systems and helps in managing the derivation task.

Model Driven Development

Johan Lilius Ivan Porres

Model-Driven Software and System Development The goal of the Model Driven Development group at CREST is to study and develop new ways to build large software-intensive systems in practice using advanced modeling languages and toolsTheoryTool FrameworksApplications

MDDLong term research goals: Understand methods for domain driven design,Understand the foundations (structure and algorithms)of domain driven design.Results:A methodological framework verified through 2 substantial case studies (PhD Dragos Truscan)A framework for the semantics of DSL that enabled codegeneration (PhD Dag Bjrklund). A framework for metamodelling (PhD Marcus Alanen)

MDD (cont)Middle term research goals: Implementation of theoretical results in tool frameworksResultsCORAL - A tool to define, edit and transform visual modeling languages: Modeling language definition, Visual languages and editors, Model transformation, Model interchangeRialto - A language for multiple models of computation: Flexible definition of behavioral semantics

MDD(cont.)Short term research goals: Verify our more theoretical results in practice, Apply the tool frameworks, provide feedback to middleand long term goalsResultsMICAS platform: Tool for definition of mobile phone subsystemsPECOS: Tools and methods for verification of non-functional constraints (energy) in mobile phone subsystemsFuture topicsModel based testingDealing with non-functional constraints in system design Version control
