3
Background Sample
  • Background
  • Survey and study are based on research started in
    Colorado
  • Survey topics include hours worked, staff
    activities, students use of the library, library
    resources including computers, library budget,
    interactions with the local public library, and
    district-level support
  • Sample
  • Surveys sent to all K-12 public school libraries
    last spring
  • 656 School librarians completed the survey (36
    response rate)
  • Sample of respondents is very similar to the
    overall population of school libraries in terms
    of size and location

Response Rates and Sample Sizes by Level
5
Data Sources
  • Data on student and school characteristics
    maintained by OSPI
  • Census data on community level characteristics
    (like adult education levels)
  • The number and percentage of students passing the
    Reading portion of the WASL in 2001, 2002, and
    2003 (data for the 3 years was combined for the
    study)
  • The online survey completed by 656 school
    librarians

6
Study Objectives
  • Objective 1 Determine whether library quality
    has an effect on students WASL performance
  • Objective 2 Identify factors that contribute or
    correlate with student learning
  • Objective 3 Examine characteristics of better
    performing libraries

7
Objective 1Does library quality have an effect
on student learning?
8
Creating the initial model
  • We identified the community and school
    characteristics that best predict the percentage
    of students passing the reading WASL.
  • Separate models were developed for Elementary,
    Middle, and High Schools.
  • Data elements included
  • From OSPI Students receiving free reduced
    price lunch, student ethnicity, teacher education
    and experience, school enrollment,
    student-teacher ratios, urban/rural location
  • From Census Number of families children in
    poverty, household income, and adult educational
    attainment

9
Elementary School Base Model
  • A model was developed that explained 69 of the
    variance in the percentage of students passing
    the Reading WASL
  • Variables in the model are
  • Percent of students receiving free or reduced
    price lunch
  • Student racial composition
  • Average years of teacher experience
  • Percent of adult females in the community who
    earned at least an Associate of Arts degree
  • Total school enrollment
  • Whether the school is in an urban or rural part
    of the state

10
Middle School Base Model
  • A model was developed that explained 82 of the
    variance in the percentage of students passing
    the Reading WASL
  • Variables in the model are
  • Percent of students receiving free or reduced
    price lunch
  • Student racial composition
  • Percent of adults in the community who earned at
    least an Bachelors degree
  • Percent of children in poverty
  • Percent of individuals in poverty

11
High School Base Model
  • A model was developed that explained 67 of the
    variance in the percentage of students passing
    the Reading WASL
  • Variables in the model are
  • Percent of students receiving free or reduced
    price lunch
  • Student racial composition
  • Percent of adults in the community who earned at
    least an Bachelors degree
  • Per student expenditures at the district level

12
Creating the enhanced model with library survey
data
  • To each of these models, survey data about school
    libraries was added to see if any aspects of the
    quality of libraries have a statistically
    significant impact on the percentage of students
    passing the WASL.

13
Elementary School Significant Library Factors
  • Adding variables from the library survey
    increased the precision of the model for
    elementary schools by 3 percentage points
  • Variables with a statistically positive effect on
    WASL scores include
  • Number of classroom visits to the library
  • Non-classified library staff hours per week
  • Number of volunteers assisting in the library
  • Hours doing collection development
  • Number of types of interactions between school
    and local public library

14
Middle School Significant Library Factors
  • Adding variables from the library survey
    increased the precision of the model for middle
    schools by 2 percentage points
  • Variables with a statistically positive effect on
    WASL scores include
  • Number of volunteers assisting in the library
  • Hours library staff spent on all teaching-related
    activities

15
High School Significant Library Factors
  • Adding variables from the library survey
    increased the precision of the model for high
    schools by 1 percentage point
  • The only variable with a statistically positive
    effect on WASL scores was
  • Number of books per student

16
Objective 2Other Factors that Correlate with
WASL Performance
17
Identifying Other Factors
  • Regression model allows for the exploration of
    factors that contribute to student performance,
    while taking into account other local
    characteristics
  • Quartile analysis identifies factors that are
    related to student performance but does not test
    whether it is independently important or simply
    related

18
Quartile Analysis Methodology
  • The regression models that did not use survey
    data (explained in the previous section) were
    used to predict the percentage of students who
    would pass the reading WASL given the number of
    people with free or reduced price lunch, adult
    education levels, etc.
  • The predicted value from the model for each
    school was compared to the actual percentage who
    passed the reading portion of the WASL in 2001,
    2002, and 2003.
  • Schools were ranked by how much they exceeded or
    fell short of their predicted scores.

19
Quartile Analysis Methodology (continued)
  • The survey responses from the top 25 of schools
    (generally those who did 3 to 6 better than
    predicted) were compared to the bottom 25 (3 to
    6 below predicted)
  • Results are reported if there is a statistically
    significant difference between the two mean
    values
  • The analysis focused on student performance on
    the reading portion of the WASL only

20
Elementary Factors Affecting Reading
  • The following have statistically significant
    differences (top 25 and bottom 25)
  • Positive Difference
  • Percent of books that are science related (12
    vs. 9)
  • Number of science books published in last 5 yrs
    (270 vs. 182)
  • Percent of science books published in last 5 yrs
    (23 vs. 19)
  • Total circulation (823 vs. 788)
  • Negative Difference
  • Dollars from Title V (442 vs. 954)
  • Note Values marked with are computed on a
    per-student basis and displayed for a typical
    elementary school of 400 students.

21
Middle School Factors Affecting Reading
  • The following have statistically significant
    differences (top 25 and bottom 25)
  • Positive Difference
  • Number of CD-Rom and online resources (4.2 vs.
    2.6)
  • Dollars from Other (1,652 vs. 665)
  • Volunteer hours per week (2.6 vs. 0.9)
  • Number of volunteers (1.9 vs. 0.8)
  • Number of hours spent on teaching activities per
    week (22.0 vs. 18.9)
  • Negative Difference
  • Total library budget (14,104 vs. 15,920)
  • Note Values marked with are computed on a
    per-student basis and displayed for a typical
    middle school of 700 students.

22
High School Factors Affecting Reading
  • The following have statistically significant
    differences (top 25 and bottom 25)
  • Positive Difference
  • Number certified librarian hours per week (50
    vs. 35)
  • Negative Difference
  • Overtime hours on all other non-library
    activities (0.6 vs. 6.7)
  • Note Values marked with are computed on a
    per-student basis and displayed for a typical
    high school of 1,100 students.

23
Objective 3Examine the Characteristics of
Better Performing Libraries
24
Section 3 Methodology
  • As with the section above, the predicted value
    from the model for each school was compared to
    the actual percentage who passed the reading
    portion of the WASL in 2001, 2002, and 2003.
  • Schools that did better than their predicted
    score were identified as better performing
    schools. This is approximately half of the
    sample.
  • The average responses for the group of better
    performing schools and for all schools were
    tabulated.
  • No statistical test was used. The differences
    between the groups were considered and the most
    noticeable are mentioned here.

25
Better Performing Elementary Schools
  • What are the differences between the better
    performing schools and elementary schools in
    general? The better performing schools have
    the following characteristics
  • More likely to be flexibly scheduled
  • Fewer paid staff working fewer hours
  • More volunteers
  • Less time teaching non-library subjects, more
    time focused on library work
  • More circulation of materials in a typical week
  • Fewer books but more other catalogued holdings
  • Slightly more computers in building that are
    directly linked to library
  • Smaller overall library budget
  • More book talks presented by the public library
  • More homework alerts provided to the public
    library

26
Better Performing Middle Schools
  • What are the differences between the better
    performing schools and middle schools in
    general? The better performing schools have
    the following characteristics
  • More volunteers
  • More individual students using the library and
    fewer groups
  • More circulation of materials and in-library use
  • Fewer books and other catalogued holdings
  • Fewer technology demonstrations by public library
    staff
  • Fewer shared networks links with public library
  • More cataloging assistance from district

27
Better Performing High Schools
  • What are the differences between the better
    performing schools and high schools in general?
    The better performing schools have the
    following characteristics
  • More credentialed librarian staff and hours and
    fewer classified and other paid staff
  • Fewer individuals using the library
  • Less circulation of materials but more in-library
    use (in-library use is greater than circulation)
  • More other catalogued holdings (besides books)
  • Older science collection
  • More computers with access to library databases
  • Fewer book talks presented by the public library
  • Fewer technology demonstrations by public library
    staff
  • More reference questions directed to the public
    library
  • More shared access to the public library catalog
  • More shared access between school and ESD
    resources

28
Using Library Survey Data
  • Use State Level Results for
  • Examining building WASL Reading scores
  • Allocating resources to types of school libraries
  • Understanding the characteristics of better
    performing libraries
  • Use Survey Average and Better Performing School
    Data for
  • Comparing your library/media center to the
    average and better performing models by-
  • Service, staffing, use collections, budget
  • Staff roles, training, work load,
    teaching/learning time, technology use to the two
    averages
  • Comparing library/media centers within a district

29
