The emergence of Do-It-Yourself (DIY) science movements is becoming a topic widely discussed in academia and policy, as well as by the general public and the media. While DIY approaches enjoy increasing diffusion even in official research, different social actors frequently talk about them in different ways and circumstances. Interaction and negotiation processes amongst actors (e.g. policy makers and DIY communities) define the premises upon which different conceptualisations of DIY science are deployed.

In this paper we offer a framework for analysing the discourse on DIY science.

Our study consists of a field research of three spaces active in DIY science premises, two dedicated events of the DIY community, and an auto-ethnography in the field of DIY biology.

By relying on the theory of social worlds/arenas (SW/A), we collected data on how notions of DIY science are constructed by different social actors and how conceptual borders are built or are likely to shift, resulting in multiple possible SW/A mappings. We conclude that each and every conceptualisation of DIY science cannot stand independently from the situatedness of its multiple contexts, therefore making its usage in policy making and governance particularly complex.

DIY（DIY）科学运动的出现正在成为学术界、政策界以及公众和媒体广泛讨论的话题。尽管 DIY 方法在官方研究中也日益普及，但不同的社会参与者经常以不同的方式和情况谈论它们。参与者（例如政策制定者和 DIY 社区）之间的互动和谈判过程定义了 DIY 科学的不同概念的部署前提。

在本文中，我们提供了一个分析 DIY 科学话语的框架。

我们的研究包括对 DIY 科学场所活跃的三个空间的实地研究、DIY 社区的两次专门活动以及 DIY 生物学领域的自动民族志。

通过依靠社会世界/领域（SW/A）理论，我们收集了有关不同社会参与者如何构建 DIY 科学概念以及概念边界如何建立或可能转变的数据，从而产生多种可能的 SW/A映射。我们的结论是，DIY 科学的每一个概念都不能独立于其多重背景的情境，因此使其在政策制定和治理中的使用特别复杂。
