Computer science teacher training at the University of Groningen

The University Center for Academic Learning and Teaching (UOCG) provides the University of Groningen with an educational program to train fully qualified secondary school teachers in many secondary school subjects including computer science. This two-year Master's in Education Program consists of teacher training that includes a large internship component and teacher training courses, in addition to those courses provided by the faculties. During the internship, the secondary school where the internship takes place is in charge of a substantial part of the teacher training, while the University's role is mainly a supervisory one

Architectural Considerations for Extending a Relational DBMS with Deductive Capabilities

This paper describes the development rationale and the architecture of a prototypical expert-database system. Knowledge processing capabilities of SQL were enhanced by extending the language by recursive views. This work is based on an evolutionary approach; smooth integration with the base language was an important development aim. After a discussion of the main design alternatives, the architecture of a prototype is presented. Finally the progress of the project is described and possibilities for further extension are indicated. 1 Recursive Views 1.1 Motivation A host of modern applications demand knowledge processing capabilities in combination with the support of large scale volume data processing capabilities and multi-user support for concurrent access and flexible combination of persistent information as provided by todays data base systems. But classical expert system shells lack important features needed in conjunction with bulk transaction processing, support for pers..
