  1. Searching and Using Electronic LiteratureIII. Research Design

  2. Framework for Empirical Research of Human Behavior • Paradigms • positivist • naturalistic • dualistic A research design is guided by a paradigm using a methodology • Methodologies • quantitative • qualitative • pluralistic

  3. Classic Method for Observation • Experiment (rigid standards exist) • randomization • treatment • to find cause-effect (relationship between dependent and independent variables) • to test hypothesis based on statistical significance of quantitative data

  4. Alternative Method • Naturalistic experiment • observing real behaviors in real life • subject's own environment • to describe behavior • to interpret or model behavior • typical data: interactions, verbalized thoughts, diaries, participant-observations, interviews • longitudinal

  5. Research Questions 1. How are electronic literature retrieval systems used in finding useful information for class-related tasks by faculty and undergraduate students? • What type of information is used for selecting documents? • What type of information is used for defining topics?

  6. Research Questions (cont’d) 2. What are the search processes? • Which system functions are used and how? • What problems related to system do users encounter during the search? 3. Are there any differences between faculty and students? What are the differences if any?

  7. Experimental design • Participants • Participants from Phase I • New participants with similar backgrounds • Simulated class-related tasks • Faculty: conducting a search for literature to design a course assignment • Students: conducting a search for literature to complete a course assignment

  8. Data Collection • Behavior • Search process (video) • Think-aloud during searching (audio synchronized with video) • Topic description before searching • Topic description after searching • Post search input • Cognitive trait • Learning style

  9. Data Analysis (Plan) • Transcribing data • Verbalization (reasons for certain actions) • Search formulation / reiteration • Screen action • Selection behavior • Coding
