ABSTRACT

The aim of this study was to analyse the effect of the visiting-scientist approach supported by conceptual change activities on high school students’ images of scientists and perceptions of gender and risks that scientists take. Twenty-five students attending 10th grade in the 2017–2018 academic years participated in the study. A quasi-experimental model with a pretest and a post-test without a control group, one of the quantitative research techniques, was used. In the implementation, activities based on conceptual change and the visiting-scientist approach of were carried out. To determine students’ scientist images, A ‘Draw-a-Scientist-Test’ and a ‘Scientist-in-Images-Scale’ were administered before and after the implementation, and interviews exploring their drawings were conducted. Similarly, the ‘Gender-of-Scientists-Perception-Scale’ and ‘Risks-of-Being-a-Scientist-Perception-Scale’ were conducted to determine students’ perceptions of the gender of scientists, and the risks encountered by the scientists. A descriptive analysis approach was used for the analysis of qualitative data collected before and after the implementation, and a Paired-Sample t-test and Wilcoxon signed-rank test were used for the analysis of quantitative data. As a result of the analysis, it was found that, after the implementation, students thought of the scientist less stereotypically and their roles less risky than they believed before.

摘要

这项研究的目的是分析概念改变活动支持的访问科学家方法对高中学生的科学家形象，性别观念和科学家承担的风险的影响。在2017-2018学年期间，有25位就读10年级的学生参加了这项研究。使用具有无对照组的前测和后测的准实验模型，这是一种定量研究技术。在实施过程中，开展了基于概念变化和的访问科学家方法的活动。为了确定学生的科学家形象，在实施前后分别进行了“绘画科学家测试”和“图像科学家比例”，并进行了探访他们的绘画的访谈。相似地，进行了“科学家的性别认知量表”和“科学家的感知风险量表”，以确定学生对科学家性别的看法以及科学家所面临的风险。使用描述性分析方法对实施前后收集的定性数据进行分析，并使用配对样本t检验和Wilcoxon符号秩检验对定量数据进行分析。分析的结果表明，实施该计划后，学生对科学家的看法比以往更少了，而且对他们的角色的冒险也比以前想象的要少。使用描述性分析方法对实施前后收集的定性数据进行分析，并使用配对样本t检验和Wilcoxon符号秩检验对定量数据进行分析。分析的结果表明，实施该计划后，学生们对科学家的看法比以往少了成见，他们的角色也比以前想象的要冒险。使用描述性分析方法对实施前后收集的定性数据进行分析，并使用配对样本t检验和Wilcoxon符号秩检验对定量数据进行分析。分析的结果表明，实施该计划后，学生对科学家的看法比以往更少了，而且对他们的角色的冒险也比以前想象的要少。
