这篇文章探讨了教师、科学家、青年和社区组织者共同努力开发一门回应社区关注和下一代科学标准(NGSS)的课程时所产生的紧张关系。在城市重金属污染的背景下,在先前对标准的批评的基础上,我们确定了NGSS的意识形态承诺如何阻碍了它们对社区问题的适用性。我们研究了绩效预期(pe)和学科核心思想中潜在的意识形态承诺,因为它们与城市重金属污染的历史和当前原因和后果有关。科学企业和化工行业既会产生危害,也会产生效益,而NGSS只关注效益,忽略了科学的危害和效益是不均匀分布的。鉴于教师实施NGSS的压力,本文介绍了合作课程开发工作的例子,这些工作既满足PEs的要求,又推动学生提出关键问题,并与社区互动,挑战标准与化工行业的一致性。最后,我们认为NGSS将教师定位为科学事业现状的推动者,我们记录了科学教师在美国学校扮演更具变革性角色的可能性。
This article examines the tensions that arose as teachers, scientists, youth, and community organizers worked to develop a curriculum that was responsive to community concerns and the Next Generation Science Standards (NGSS). Within the context of urban heavy metal contamination and building on previous critiques of the standards, we identified how the ideological commitments of the NGSS hinder their applicability to community issues. We examine latent ideological commitments in the performance expectations (PEs) and disciplinary core ideas as they relate to historical and present causes and consequences of urban heavy metal contamination. Whereas the scientific enterprise and chemical industry produce harms and benefits, the NGSS focus on benefits and ignore that both harms and benefits of science are unevenly distributed. Given the pressure on teachers to implement the NGSS, this paper presents examples from collaborative curriculum development efforts that meet PEs while pushing students to ask critical questions and engage with their communities to challenge the standards’ alignment with the chemical industry. Ultimately, we argue that the NGSS position teachers as promoters of the status quo of the scientific enterprise and we document possibilities for the role of science teachers in US schools that are more transformative.
