Girls are underrepresented in mathematical and science Olympiads, global informal learning activities which often serve as stepping stones for admission to top universities and future STEM careers. The present article aims to investigate the role of implicit gender‐science stereotypes on representation and achievement among participants of the German Chemistry Olympiad using a cross‐sectional online study (N = 445, mean age 16.5 years, 51% female) entailing the Implicit Association Test and two motivational scales. This study was the first of its kind to use moderated mediation analysis to examine the effects of gender‐science stereotypes on participation and achievement, mediated by the expectancy and value beliefs self‐concept and topic interest. We found that in the female group, gender‐science stereotypes negatively predicted the participants' willingness to continue in the competition. This relationship was mediated through topic interest. In addition, we found self‐concept predictive for further participation among female participants, as well as for competition score among both gender groups. Furthermore, topic interest positively predicted male participants' willingness to continue with the competition. The results underline the negative association of implicit gender stereotypes with female participation in the German Chemistry Olympiad. Organizations such as the German Chemistry Olympiad should therefore critically reflect on existing gender biases within their own structure. In doing so they can create an environment that has the potential to heighten self‐concept and interest for all participants equally. Our findings add to existing expectancy‐value research in the context of gender differences in mathematics and science, supporting potential strategies toward gender equity.

在化学奥林匹克竞赛中实现性别平等的第一步：了解内隐的性别科学定型观念的作用

女孩在数学和科学奥林匹克竞赛，全球非正式学习活动中所占的比例不足，这些活动通常是入读顶尖大学和未来STEM职业的垫脚石。本文旨在通过横断面在线研究，探讨内隐性别科学定型观念对德国化学奥林匹克竞赛参与者代表性和成就的作用（N= 445，平均年龄16.5岁，女性占51％），并进行了内隐联想测验和两个动机量表。这项研究是同类研究中的第一个，它使用中度调解分析来检验性别，科学定型观念对参与和成就的影响，这是由期望和价值信念，自我概念和主题兴趣所介导的。我们发现，在女性群体中，性别科学定型观念负面地预测了参赛者继续比赛的意愿。这种关系是通过话题兴趣来调解的。此外，我们发现自我概念可以预测女性参与者的进一步参与以及两个性别群体之间的竞争得分。此外，话题兴趣积极地预测了男性参与者继续比赛的意愿。结果强调了内隐性别刻板印象与德国化学奥林匹克运动中女性参与的消极关联。因此，像德国化学奥林匹克运动会这样的组织应该批判性地反思其自身结构中现有的性别偏见。这样，他们可以创造一种环境，有可能平等地提高所有参与者的自我概念和兴趣。我们的发现增加了数学和科学领域性别差异背景下的现有预期价值研究，为实现性别平等的潜在策略提供了支持。这样，他们可以创造一种环境，有可能平等地提高所有参与者的自我概念和兴趣。我们的发现增加了数学和科学领域性别差异背景下的现有预期价值研究，为实现性别平等的潜在策略提供了支持。这样，他们可以创造一种环境，有可能平等地提高所有参与者的自我概念和兴趣。我们的发现增加了数学和科学领域性别差异背景下的现有预期价值研究，为实现性别平等的潜在策略提供了支持。
