The purpose of this study is twofold: first, to delve into professional development (PD) of science teachers’ views about nature of science (NOS) throughout activities linking NOS aspects to science centers (SCs), and second, to reveal how a science teacher uses NOS aspects while teaching in SCs. An instrumental qualitative case study method with different data sources was used. There were 18 elementary science teachers participating voluntarily in this study. Additionally, one science teacher among the participants was observed two times during her SCs visit with her grade 6th and 7th students. Researchers trained science teachers for using the facilities of SCs and supported their understanding of NOS. Before and after the workshop, open-ended VNOS-C questionnaire was administered, and follow-up interviews were conducted. Observations in SCs were made to check whether the teacher were able to use NOS concepts while teaching science. Findings revealed that the majority of science teachers exhibited improved views about NOS, and improvement was attained particularly on the aspects of tentativeness, methods of scientific investigation, social and cultural embeddedness, and creativity and imagination, while the least improvement was noted for scientific theories and laws. During the SC visits, the teacher employed all aspects of NOS except the theory and law tenet and mostly discuss about the observation, inference, and experiment while teaching. Further PD activities are suggested to support teachers to develop their own teaching plans specific to each exhibit by employing NOS concepts for teaching with/in SCs.

科学中心的科学教师专业发展

本研究的目的有两个：首先，在将 NOS 方面与科学中心 (SC) 联系起来的活动中，深入研究科学教师对科学本质 (NOS) 观点的专业发展 (PD)，第二，揭示科学如何教师在 SCs 教学时使用 NOS 方面。使用了具有不同数据源的仪器定性案例研究方法。有 18 名小学科学教师自愿参与了这项研究。此外，参与者中的一名科学老师在她的 SC 访问期间与她的 6 年级和 7 年级学生进行了两次观察。研究人员培训科学教师使用 SCs 的设施，并支持他们对 NOS 的理解。研讨会前后，进行了开放式 VNOS-C 问卷调查，并进行了后续访谈。对 SCs 进行了观察，以检查教师在教授科学时是否能够使用 NOS 概念。调查结果显示，大多数科学教师对 NOS 的看法有所改善，尤其是在尝试性、科学研究方法、社会和文化嵌入性以及创造力和想象力方面取得了进步，而在科学理论和科学方面的进步最少。法律。在SC访问期间，老师除了理论和法律原则外，还运用了NOS的各个方面，并且在教学中主要讨论了观察、推理和实验。建议进一步开展 PD 活动，通过采用 NOS 概念与 SCs 进行教学，以支持教师针对每个展览制定自己的教学计划。
