Description¶
A researcher-administered hands-on ramp-task assessment adapted from Chen and Klahr's ramp task to measure kindergartners' control-of-variables strategy through progressively complex experiment designs and feedback.
Components¶
Claims¶
- Mokken scale analysis establishes content validity of the ramp task as a unidimensional measure of CVS use [+M]
- Ramp task levels are ordered by difficulty: performance declines as the number of variables to set increases [+W]
