approaches to the assessment of inquiry and investigation in science. TIMSS 2023 will capitalize on the
benefits of digital assessment by:
•
Incorporating a variety of technology-enhanced item formats to promote student
engagement.
•
Including simulated real-world and laboratory situations where students can integrate
and apply process skills and content knowledge to perform scientific investigations or
experiments.
•
Improving measurement of higher-order cognitive processes using interactive scenarios that
present students with adaptive and responsive ways to work through science problems.
•
Collecting information about how students interact with the achievement items to learn
more about how students engage in the practice of science, their misconceptions, and their
test-taking strategies.
The Introduction to the TIMSS 2023 Frameworks provides further detail on the new interactive item
types and response types planned for TIMSS 2023. It also describes the initiative begun in TIMSS 2019
to develop and begin administering longer, scenario based Problem Solving and Inquiry Tasks (PSIs)
in the mathematics and science assessments, and the plans for incorporating the PSIs into the TIMSS
2023 assessments and beyond.
At each grade, the science assessment framework for TIMSS 2023 is organized around two
dimensions:
•
Content dimension, specifying the subject matter to be assessed
•
Cognitive dimension, specifying the thinking processes to be assessed
Exhibit 2.1 shows the target percentage of score points devoted to each content and cognitive domain
for the TIMSS 2023 fourth and eighth grade assessments.
