3 eras of user studies observing outcomes trends in studying use why outcomes matter

• 3 Eras of User Studies

• Observing Outcomes

• Trends in Studying Use

• Why Outcomes Matter

History of Observing Use, Effects and Outcomes

Identifying origins some general comments

Identifying Origins:

Some General Comments

Three Eras


1836 1935 collections 1936 1958 documents 1959 now chunks

1836-1935: Collections

1936-1958: Documents

1959-Now: Chunks

The 3 Eras

Case LIDA


The era of collections

The Era of Collections

• Long Essential to Library

Management & Assessment

• Breakdown of Collection Use

• Collection/Services as Focus


The era of documents

The Era of Documents

• What Book/Magazine/ Paper

do Users Prefer, & Why?

• Rare: What Happens as a

Result? Outcomes of Exposure

• Shift to Qualitative Methods


The era of chunks

The Era of Chunks

• Units of Information Smaller

than a Document, e.g., an Answer

• More Emphasis on Outcomes,

e.g., Awareness or Tasks

• Scientists, Engineers, Managers


What is use

What is “Use”?

• An Ambiguous Word

Use and Outcomes


What is use1

What is “Use”?

• An Ambiguous Word

• Limited Observations

Use and Outcomes


What is use2

What is “Use”?

• An Ambiguous Word

• Limited Observations

• Effects or Applications

Rarely Measured in Past

Use and Outcomes


What is use3

What is “Use”?

• An Ambiguous Word

• Limited Observations

• Effects or Application

Rarely Measured in Past

• But More Common Now

Use and Outcomes


Lida 2014

QUANTITATIVE MEASURES, e.g.,

• Yes-No Responses to Items like

“I learned something new” or “I was reassured.”

• Scalar Responses to Statements like “I tried to relate what I read to my own experience.”

QUALITATIVE QUOTATIONS, e.g.,

• “What she told me made me feel better.”

RESEARCHER SUMMARIES, e.g.,

• “The student’s essay showed how she had paraphrased the material she read.”

What We Looked For


Lida 2014

Study

Results


Need seeking finding use

Need  Seeking  Finding  Use

Potential Explanations


Then need seeking finding use now need seeking finding use outcome

THEN:

Need  Seeking  Finding  Use

NOW:

Need Seeking Finding Use Outcome

Potential Explanations


Lida 2014

Observing Outcomes is Difficult

Qualitative Methods are Better-Suited

They were Not Popular Until the 1980s

Potential Explanations


Lida 2014

Another Potential Explanation:

Pressure from External Environment

• Parent/Funding Agencies of Libraries

Want Better Results and Justifications

Potential Explanations


Lida 2014

Pressure from External Environment

• Parent/Funding Agencies of Libraries

Want Better Results and Justifications

• LIS Scholars Face Similar Pressure, Plus Competition from Other Disciplines

Potential Explanations


Conclusions

Conclusions

• Assessing Outcomes is Important

• May Require In-Depth Methods

• Quantitative Measures Also Useful

• Yet Such Measures also have Limits
