Direct linkSchwichow, Martin; Brandenburger, Martina; Wilbers, Jens – International Journal of Science Education, 2022
Designing and interpreting controlled experiments are important inquiry skills addressed in many current science curricula. The relevant skills associated with the design and interpretation of controlled experiments are summarised under the term control-of-variables strategy (CVS). Research on elementary school students' CVS skills shows that they…

Schwichow, Martin; Zimmerman, Corinne; Croker, Steve; Härtig, Hendrik – Journal of Research in Science Teaching, 2016
The ability to design and interpret controlled experiments is an important scientific process skill and a common objective of science standards. Numerous intervention studies have investigated how the control-of-variables-strategy (CVS) can be introduced to students. However, a meta-analysis of 72 intervention studies found that the opportunity to…

Schwichow, Martin; Christoph, Simon; Boone, William J.; Härtig, Hendrik – International Journal of Science Education, 2016
The so-called control-of-variables strategy (CVS) incorporates the important scientific reasoning skills of designing controlled experiments and interpreting experimental outcomes. As CVS is a prominent component of science standards appropriate assessment instruments are required to measure these scientific reasoning skills and to evaluate the…
