中文摘要:

      公众科学态度是科普领域的重要议题。本文以心理学假设为基础编制公众科学态度的量表，并用 Rasch 模型对量表进行单维性检验、局部独立性检验、结构分析、试题项目及被试拟合分析、评定尺度分 析。经检验，本文量表可测量公众科学态度，并用于其他延伸性研究。此外，Rasch 模型还可作为微观科普 效果评估方法的补充。

英文摘要:

      Public attitudes toward science constitute a key research focus in the field of science popularization. This study develops a scale for measuring public attitudes toward science based on psychological assumptions and validates it through the Rasch Model，examining its unidimensionality， local independence，structural validity，item fit，person fit，and rating scale functioning. The validated scale effectively measures the construct of“public attitudes toward science”and can be applied in subsequent research. Additionally，the Rasch Model proves to be a valuable supplementary tool for assessing the micro-level impacts of science popularization.
