Contemporary World 3: Assessing Student
Learning
http://services.bepress.com/numeracy/
Our Course
• Uses case studies centered on one or more media
articles
• Each case study contains study questions focusing
on the quantitative content of the article
• Student responses often involve critiquing,
analyzing, decision making, and explaining.

Need: Instrument that we could apply to these
non-standard student responses.
A Little History
AAC&U VALUE Project:
•Developed for institutional level assessment (not
for grading student work)
•15 areas, 10 of which are termed Intellectual and
Practical skills:
•Inquiry and analysis, critical thinking, written
communication, oral communication, reading,
quantitative literacy, information literacy,
teamwork, problem solving

Missing Competencies?:
– Critical Reading
– Number sense
– Synthesis
Folded into “Interpretation”
Changed “application/analysis”
to “analysis/synthesis”
Scale
– No “zero”
– “4” designated capstone
achievement; not a

Added Value of QLAR
1. Allows one to align student prompts with an
organized thought process as represented by
the rubric
To solve a complex problem a student needs to read and
glean information, convert the information into a usable
form, calculate, make or draw a conclusion, and then
communicate the result via explanation.
