Evaluating the user education

Abstract

Desicusses the user training programme of the Helsinki University of Technology Library in the light of an internordic monitoring project. In the project, the use of OPACs was evaluated by analyzing the transaction logs and it was concluded that end users do not exploit the various possibilities of OPACs. A large part of the material found in the collections in the library is not retrieved: misspellings, lack of truncation, inequate use of Boolean operators and wrong database choices lead to ineffective retrieval. Emphasis in the online catalogue training has been on the 'hands on' exercises and it appears that the training programme is not very effective in the area of subject searching. Presents reasons for this and discusses plans for the future development of the library user training programme
