Jan R. Boehnke<p>For me the question remains, how would one design interventions that improve so substantially over and above this control group that their signal cuts through pupils' individual differences, teaching styles, and massive school-effects. I find this genuinely a massive challenge.</p><p>How large can these effect sizes really be?</p><p><a href="https://mastodon.social/tags/StudyDesign" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>StudyDesign</span></a></p>
