In this chapter, the pedagogical design and evaluation of interactive information retrieval learning environment is presented. The course consisted of lectures, Web exercises, and tutored search exercises. The pedagogical design of the learning environment was based on the ideas from anchored instruction and intentional scaffolding. Anchoring relat...

Information retrieval experiments usually measure the average effectiveness of the IR methods developed. Direct use of an operational retrieval system has the shortcoming that the user is not given feedback about the effectiveness of queries. The Query Performance Analyser (QPA) for information retrieval systems is an interactive tool for the perfo...

Design experiment on two information retrieval (IR) learning environments is presented. The participants in the study (n=57), were undergraduate students of information studies at the university. The pedagogical design of the experimental learning environment was based on the ideas from anchored instruction and intentional scaffolding. Anchoring re...

In order to design information retrieval (IR) learning environments and instruction, it is important to explore learning outcomes of different pedagogical solutions. Learning outcomes have seldom been evaluated in IR instruction. The particular focus of this study is the assessment of learning outcomes in an experimental, but naturalistic, learning...

The design and evaluation of two information retrieval (IR) learning environments took place in a basic course of IR (6 ECTS credits) at the Department of Information Studies at the University of Tampere. The course consisted of lectures, web exercises and tutored search exercises. Tutored exercises were carried out in two learning environments, in...

In order to design information retrieval (IR) learning environments and instruction, it is important to explore available pedagogical solutions and their impact on learning experiences and performance in learning situations. The particular focus of this study is the demonstration of how pedagogical solutions like scaffolding and anchored instructio...

To design information retrieval (IR) learning environments and instruction, it is important to explore learners' conceptions of the domain to be examined. This article addresses the issue by investigating students' conceptions of IR know-how and its implications for designing learning environments for IR. This study focuses on the integration of re...

Information retrieval experiments usually measure the average effectiveness of IR methods developed. The analysis of individual queries is neglected although test results may contain individual test topics where general findings do not hold. The paper argues that, for the real user of an IR system, the study of variation in results is even more imp...

Computer-supported learning environment (CSLE) Information Retrieval Game (IR Game) is described and evaluated. The IR Game is based on idea that test collections used in laboratorybased IR experiments could be used in instruction as a rapid query analysis tool. The goal is to provide a realistic environment for demonstrating the performance of que...

Operationaalisissa tiedonhakujärjestelmissä, kuten tietokannoissa ja www-hakupalveluissa, hakijan on mahdotonta arvioida luotettavasti, kuinka hyvin hän on omassa hakutehtävässään onnistunut. Järjestelmillä, jotka antavat palautetta haun onnistumisesta, voidaan avata tiedonhakujärjestelmien toimintaperiaatteita ja osoittaa konkreettisesti, miten er...
