what is sbr
What Is SBR?
  • U.S. Dept. of Education (No Child Left Behind)
    • Rigorous, systematic & objective procedures to obtain reliable & valid knowledge
      • Empirical methods
      • Rigorous data analyses
      • Measurements or observational methods
      • Experimental or quasi-experimental designs
      • Replication & generalization
      • Accepted by independent sources
what is sbr3
What Is SBR?
  • National Research Council (Scientific Research in Education, 2002)
    • Clear set of questions
    • Methods appropriate to answer questions & rule out competing answers
    • Accounting for previous research
    • Conceptual basis
    • Data collected & analyzed systematically
    • Clearly described & available for criticism
what is sbr4
What Is SBR?
  • Experimental & quasi-experimental design
    • Randomization v. matching v. self selection with controls (isolation of treatment variables, problem of transferring medical model to education)
    • Professional ethics (malpractice, human subjects issues, negative & side effects)
    • “Natural” experiments or quasi-experiments
  • “Appropriate methods” alternative (according to NRC): causal modeling
  • Status of qualitative research
what is sbr5
What Is SBR?
  • Types of questions
    • What is happening?
    • Is there a systematic effect?
    • How is it happening?
what is sbr6
What Is SBR?
  • Types of questions
    • What is happening?
      • Descriptive studies
      • Conceptual viewpoint
      • Reproducible protocols for recording data
      • Purposes
        • Estimating population characteristics
        • Identifying simple relationships
        • Describing local settings
what is sbr7
What Is SBR?
  • Types of questions
    • Is there a systematic effect?
      • Cause-and-effect studies
        • Correlation v. cause-and-effect
      • Controlling for antecedent & intervening variables
        • Randomization v. matching v. causal modeling
        • Ruling out competing answers
what is sbr8
What Is SBR?
  • Types of questions
    • Why or how is it happening?
      • Process studies
        • Observation and interviews
        • Ethnographic approach
        • Testing hypotheses via alternative causal models
how much of it do we have
How Much of It Do We Have?
  • Historical research on school library impact
    • “What is happening?” type (simple correlations)
    • Local studies of students or classes
    • Largely experimental or quasi-experimental
    • Most common weaknesses
      • Lack of conceptual framework
      • Minimal reliance on previous research
      • Failure to document reproducible data collection strategies
    • Gaver study as “watershed”
how much of it do we have10
How Much of It Do We Have?
  • “Colorado”-style studies
    • “Is there a systematic effect?” & “How is it happening?” types
    • Statewide studies of schools
    • Causal modeling (A leads to B leads to C, despite D) based on Information Power
    • Multivariate statistical analysis to control for competing causes
    • Norm-referenced v. standards-based test scores
how much of it do we have11
How Much of It Do We Have?
  • Krashen studies
    • What is happening?” & “Is there a systematic effect?” types
    • Print, information-rich environments
    • School & public libraries
    • Correlations between availability & usage of information resources and test scores
    • Krashen’s hypothesis about impact of poverty
how much of it do we have12
How Much of It Do We Have?
  • AASL/World Book Action Research Project
    • “What is happening?” type
    • Encouragement of local documentation of impact
    • Local academic achievement data from local, state, or national tests
    • Power reader student survey
    • Power learner student evaluation/Power learner teacher, library media specialist and administrator evaluation
how much of it do we have13
How Much of It Do We Have?
  • Student Learning Through OH School Libraries
    • “What is happening?” & “How is it happening?” types
    • “Student learning” (how) v. “academic achievement” (how much)
    • Student v. school as unit of analysis
    • Self-reported outcomes & critical incidents v. test scores
how much of it do we have14
How Much of It Do We Have?
  • Project Achievement
    • “What is happening?” & “How is it happening?” types
    • National initiative to collect and present local evidence linking school library programs to student achievement
    • Units of analysis: learner, teaching unit & organization
    • Outcomes: reading, collaboration, information literacy & technology
how can we do it better
How Can We Do It Better?
  • Improving Research
    • Elaborating conceptual frameworks (theories, standards)
    • Replicating research to improve generalizability (time, geography & politics)
    • Building on previous research
    • Combining quantitative & qualitative methods (research & political motivations)
    • Encouraging meta-analysis of research
how can we do it better16
How Can We Do It Better?
  • Disseminating research findings (getting past the choir)
    • White House conference
    • AASL Administrator Day
    • What Works Clearinghouse
    • Books, articles & presentations aimed at educator community
how can we do it better17
How Can We Do It Better?
  • Applying findings (evidence-based practice)
    • Politicization of education policy & research (tail wags dog)
    • Gap between research & practice
    • Bureaucratic pressures on practitioners v. freedom from “publish or perish” mentality (can’t see forest for trees)
