The translation and adaptation of an assessment instrument into another language can be problematic, due, among other reasons, to sociocultural differences. This proved to be the case with the Spanish adaptation of the Students' Understanding of Models in Science (SUMS) questionnaire, a Likert-type scale developed originally in English. In light of this, and with the additional aim of improving upon certain aspects of the original instrument, we report the development of a new questionnaire for assessing Spanish-speaking students' understanding of the nature of models and their uses in science, providing validity evidence for the internal structure of the construct measured. The tool was developed by considering various dimensions of this concept that have been described in the literature, as well as the results of studies that piloted the SUMS questionnaire. For each dimension we drew up a set of items that could be rated using a Likert-type scale; half of these items were positively worded with respect to an adequate understanding of models, and half were reverse worded. The adequacy of the proposed items was first assessed by a panel of experts, following which we examined the score structure obtained with the resulting instrument by administering it to a sample of 1272 students aged between 14 and 55 years. After purifying the instrument based on the results of these analyses, we obtained a final version of the questionnaire comprising 20 items distributed equally across four subscales: Beyond exact replicas, Purpose of models, Multiple models, and Changing models. The results obtained through factor analysis and structural equation modeling provide validity evidence for the internal structure of the construct measured. The questionnaire is quick to administer and is applicable to students across a wide range of ages and levels of education, including prospective science teachers.

用于评估讲西班牙语的学生对模型的性质及其在科学中的用途的理解的调查问卷的开发

由于社会文化差异等原因,将评估工具翻译和改编成另一种语言可能会出现问题。事实证明,西班牙改编的学生对科学模型的理解 (SUMS) 问卷就是这种情况,这是一种最初用英语开发的李克特型量表。鉴于此,为了改进原始工具的某些方面,我们报告了一个新问卷的开发,用于评估讲西班牙语的学生对模型的性质及其在科学中的用途的理解,提供有效性证据用于测量构造的内部结构。该工具是通过考虑文献中描述的这个概念的各个方面而开发的,以及对 SUMS 问卷进行试点的研究结果。对于每个维度,我们都制定了一组可以使用李克特型量表进行评分的项目;在充分理解模型方面,这些项目中有一半的措辞是积极的,而另一半则是相反的措辞。建议项目的充分性首先由一个专家小组评估,随后我们通过对 1272 名年龄在 14 至 55 岁之间的学生的样本进行管理,检查了由此产生的工具获得的分数结构。根据这些分析的结果净化工具后,我们获得了问卷的最终版本,包括 20 个项目,平均分布在四个子量表中:在充分理解模型方面,这些项目中有一半的措辞是积极的,而另一半则是相反的措辞。建议项目的充分性首先由一个专家小组评估,随后我们通过对 1272 名年龄在 14 至 55 岁之间的学生的样本进行管理,检查了由此产生的工具获得的分数结构。根据这些分析的结果净化工具后,我们获得了问卷的最终版本,包括 20 个项目,平均分布在四个子量表中:在充分理解模型方面,这些项目中有一半的措辞是积极的,而另一半则是相反的措辞。建议项目的充分性首先由一个专家小组评估,随后我们通过对 1272 名年龄在 14 至 55 岁之间的学生的样本进行管理,检查了由此产生的工具获得的分数结构。根据这些分析的结果净化工具后,我们获得了问卷的最终版本,包括 20 个项目,平均分布在四个子量表中:随后,我们通过对 1272 名年龄在 14 至 55 岁之间的学生的样本进行管理,检查了由此产生的工具获得的分数结构。根据这些分析的结果净化工具后,我们获得了问卷的最终版本,包括 20 个项目,平均分布在四个子量表中:随后,我们通过对 1272 名年龄在 14 至 55 岁之间的学生的样本进行管理,检查了由此产生的工具获得的分数结构。根据这些分析的结果净化工具后,我们获得了问卷的最终版本,包括 20 个项目,平均分布在四个子量表中:超越精确复制品模型目的多个模型变化模型。通过因子分析和结构方程建模获得的结果为所测构念的内部结构提供了有效性证据。该问卷可快速管理,适用于各种年龄和教育水平的学生,包括未来的科学教师。
