- Does library quality have an effect on student
learning? - Other factors related to student learning
- Characteristics of better performing libraries
- How to use the data from the survey at your

3Background 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
4Response Rates and Sample Sizes by Level
5Data 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
6Study 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
7Objective 1Does library quality have an effect
on student learning?
8Creating 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
9Elementary 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
10Middle 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
11High 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
12Creating 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.
13Elementary 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
14Middle 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
15High 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
16Objective 2Other Factors that Correlate with
WASL Performance
17Identifying 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
18Quartile 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.
19Quartile 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
20Elementary 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.
21Middle 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.
22High 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.
23Objective 3Examine the Characteristics of
Better Performing Libraries
24Section 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.
25Better 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
26Better 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
27Better 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
