Can focusing on the understanding sub-skill lead to enhanced mastery of the control of variable strategy? — Stephanie Steindl and •Michael M Hull — Universität Wien, Wien, Österreich

Since the mid-20th century, education researchers across disciplines have investigated how to better teach experimental competencies. The control-of-variable-strategy (CVS) is a fundamental part of experimental knowledge acquisition, as it allows the researcher to draw valid conclusions about cause-effect-relationships in experiments where only one variable is changed. Researchers have postulated CVS as being comprised of sub-skills, with the sub-skill "understanding the indeterminacy of confounded experiments (UN)" being the most difficult for students to master. Schwichow et al. (2020) proposed that direct instruction in the UN sub-skill might result in mastery of the UN-skill before or at the same time as the remaining sub-skills. In this presentation, I will discuss my investigation of this proposal, where I measure the effect of different interventions on the overall CVS-skills.
