Assessment Resource Tools for Improving Statistical Thinking (ARTIST)
The goal of the Web-based ARTIST is to help teachers asses statistical literacy, statistical reasoning and statistical thinking.
The ARTIST website provides a variety of assessment resources for teaching first courses in statistics and contains:
 Item Database: a collection of over 1,200 items organized by topic and learning outcome
 11 Assessment Topic Scales and the Comprehensive Assessment of Outcomes in a first Statistics Course (CAOS)
 Information, guidelines, and examples of alternative assessments
 Information on implementation issues related to designing, administering, and evaluating assessments
 Direct links to or copies of articles on assessment in statistics
 References and links to other related assessment resources
 Copies of conference papers and presentations on the ARTIST project and handouts from ARTIST mini-courses
 Information on upcoming ARTIST events
 Information about ways to participate as a scale tester

Interview Protocol for
Frequent ARTIST Users
The interviews were conducted
to collect information about
today’s instructors of statistics
assessment practices. The
information was used to tailor the
other evaluation instruments.
Participants were statistics
instructors known by the
educational resource directors.
The survey was created and
administered to collect
information about the web
design, the web content, and
implementations in educational
settings.
All registered ARTIST users
teaching introductory statistics in
the US, who had accessed the
website since August 2004, and
who were teaching that semester
were invited.
The survey was created and
administered to collect
information about the non-users’
characteristics.
Invitations for submitting the
survey were sent by e-mail to the
following list serves: isostat
group, ASA Stat ed, and the
sigmaa listserv.
The interviews for frequent
ARTIST users were conducted to
collect information about
implementations in educational
settings and educational impact.
Participants were selected based
on the number of ARTIST topic
scales and ARTIST items they
had administered to their
students.

Observation Protocol for FirstFrequent Item Database Users
Time Item Database Users
The observations were conducted
to collect information about the
navigatability of the Item
Database. We wanted to learn
where the Assessment Builder
was difficult to use, even for
experienced users.
Participants were asked to
conduct a think-aloud while
performing certain tasks, such as
create a test, add a question to
that test, remove a question.

Evaluation Findings
1. Web design: concrete recommendations have been made to improve the web design
2. Web content: recommendations have been made to include large data sets to the Item
Database and to add additional item topics.
3. Use: Many statistics educators are actively using ARTIST and value the resource. The main
reasons for statistics educators to not use ARTIST are time and misconceptions about what
ARTIST has to offer. Because of the evaluation, several non-users became more aware of
goal of ARTIST and started using ARTIST since.
4. Educational impact: instructors are changing assessment practices but there is no impact
yet on student outcomes because, so far, newly developed ideas have not been implemented
by instructors.
