"A profession without reflective practitioners who are willing to learn about relevant research is a blinkered profession - one that's disconnected from best practices and best thinking, and one which, by default, often resorts to advocacy rather than evidence to survive." Ross Todd (2008).

man with pie chartShe's a great library media specialist.

His library is always filled with enthusiastic students.

Her students always create great projects.

These are wonderful accolades about teacher librarians, but how do we know for a fact that these wonderful media specialists are effective? How do we know that the library media program impacts student performance? How can we demonstrate our worth to the school board in facts, not just anecdotes? We need evidence.

Evidence based practice is the systematic process of documenting how a teacher librarian makes a difference in student learning.

Is this realistic for library media specialists?

When classroom teachers and teacher librarians are collaborating on activities to impact student learning, it makes sense to collect data about the effectiveness of the activity. Traditional student assessments such as test score, rubrics, and checklists are the place to begin. However there are many other types of evidence that can be collected through the library media center such as circulation statistics and learning logs.

What are evidence-based strategies?

David Loertscher suggests three evidence-based strategies (Loertscher, 2003):

Ongoing Data Collection. Involves using various information gathering techniques to monitor progress regularly. Data may be collected daily, weekly, monthly, or other regular measures. Techniques may include real-time tracking (i.e., hits at website), periodic gathering (i.e., check blog), or project collecting (i.e., end of project).

Also read a recent report of initial data gathered from Surveys of Indiana School Library Media Specialists 2003-2004 (Nov. 2004) (MS Word document will download to desktop). This study was an effort of the Association for Indiana Media Educators (AIME) in collaboration with the Indiana University School of Library and Information Science and the IU Public Opinion Laboratory at Indianapolis on the IUPUI campus.

Evidence-based Practices. Involves measuring effectiveness as the event occurs such as counting the use of proper citations in student PowerPoint presentations a few days after a mini-lesson on citing sources.

Action Research Projects. Involves conducting a formal study addressing specific questions about program effectiveness.

What is Project Achievement?

David Loertscher spearheaded a national initiative called Project Achievement focusing on the collection and presentation of evidence that connects library media programs to student achievement.

info power"significant measures that are most likely to produce results in achievement and indicate maximum teacher collaboration and organization effectiveness. Because you have these data, a ripple effect occurs, like throwing a pebble in a pool, triggering many other organizational practices and policies." David Loertscher (2003)

Loertscher's four measurement areas include:

Evidence is collected from three perspectives creating triangulation. This means gather evidence from various perspectives (Loertscher & Woolls, 2003):

The roles of teachers and librarians in the program are emphasized.

The paper proposes a national agenda to demonstrate the postitive influences of effective school librarians and qualit school libraries on student learning.

Check Your Understanding

info power"What is evidence-based practice and how can it work for you? First coined by the medical profession in the early 1990s, evidence-based practice can now be applied to what you do to show how and why your services are important to student learning. Start by familiarizing yourself with existing research on how school libraries can optimize learning. Then make sure you systematically focus on gathering meaningful evidence on the impact of your instructional role on student achievement."
Todd, Ross (April 2003). Irrefutable Evidence: How to Prove You Boost Student Achievement (Access requires Login). School Library Journal.

Loertscher and others have written about using direct and indirect measures as ways to collect evidence. If those terms are fuzzy or unknown to you, here is a brief explanation:

There are many ways to collect evidence, and assessments can be categorized as being either direct or indirect measures.

Direct measures are most often used. A direct measure refers to measuring the thing that you want to measure; measuring actual work, measuring a sample of work including exams, projects, demonstrations, performances, and other completed work. The strength of direct measurement is that you are capturing a sample of what was done, which can be very strong evidence. A possible weakness of direct measurement is that not everything can be demonstrated in a direct way; things such as values, perceptions, feelings, and attitudes.

In contrast, an indirect measure is when you measure something by measuring something else. At first that may sound strange, but an indirect measure is based upon a report of perceived work. These reports can come from varied perspectives such as students, teachers, staff members, and others. Indirect measures provide added information (information that cannot be directly measured) about what happened, what was completed, and what is valued by different constituencies.

Indirect measures are not as strong as direct measures, because one has to make assumptions about what exactly this type of self-reporting means. For example, if someone reports that a student has performed a specific task, how do we know that their assessment is accurate? The strength of indirect measurement is that it can assess certain implicit qualities such as values, feelings, perceptions, and attitudes from a variety of perspectives. The weakness of this approach is that in the absence of direct evidence, assumptions must be made about how well perceptions match the reality of actual achievement.

Make It Real

Your principal has announced that each department begin collecting evidence of the effectiveness of their program. You've been given David Loertscher's handout as a recommended place to start with the library media program. Read Project Achievement: Brief Guide and Handouts (PDF document, 2003).

You have two options:

Option 1

Select one of the four areas: reading, collaboration, information literacy, or technology described by Loertscher. Select particular aspects of the guidelines or samples that you think would be particularly worthwhile. Would you select an emphasis or make your project more general? Would you use the entire school or focus on a particular grade level or subject area? What direct and/or indirect measures would you use? Why?

Discuss how you would go about convincing your teachers to participate in this type of evidence-gathering activity. Your arguments should be aimed at the average overworked and underpaid teacher who may not be as enthusiastic as you are about this project.

Option 2

Develop a new measurement area or a subset of one of the basic four (i.e., primary sources, current events). Use the Collecting the Data project for ideas. Apply ideas from the four areas provided as examples. Create a Library Media Center Program Ripple Effect Measures page for your topic including LMC Agenda goals, Curriculum Agenda goals, pebbles to measure, justification, demonstrate through research and practice that..., and report.

Discuss why you think this approach would be effective with this topic.
