摘要

本研究旨在开发一种具有有效性和可靠性的测量工具,以确定在教育学院工作的院士们对其向职前教师提供专业价值观的责任的看法。为了创建量表所需的项目库,我们查阅了相关文献,并在此基础上创建了一个包含 44 个项目的问题库,同时还听取了专家的意见。在对项目进行修订后,采用 Lawshe 技术确定其内容效度。对 300 名教职员工进行了量表施测,获得了一组数据,并对其进行了效度和信度分析。采用探索性因子分析(EFA)揭示量表的建构效度,采用 Cronbach's Alpha 信度系数、项目-总分相关性和二分之一测验信度方法确保量表的信度,采用低 27%-高 27%独立组 t 检验对量表进行区分。经过 EFA 分析,形成了 26 个项目的 3 因子结构。该结构解释了量表总方差的 59.647%。量表信度的 Cronbach Alpha 内部一致性系数为 0.952。据观察,各项目总相关值均高于 0.5 且呈正相关,所有项目的相关值均高于 0.30,这是建议的下限。根据两次半测验的信度分析结果,等效半测验之间的相关系数为 0.942。为了考察量表项目的区分度,对高 27%组和低 27%组的得分进行了 t 检验,结果发现,在 α=.000 的水平上,组间差异显著。

Scale Development Study on the Perception of Responsibility for Providing Professional Value for Prospective Teachers
In this study, it was aimed to develop a measurement tool with validity and reliability to determine the perceptions of academicians working in faculties of education about their responsibility to provide pre-service teachers with professional values. In order to create the necessary item pool for the scale, the literature was reviewed and in this context, a question pool of 44 items was created and expert opinions were taken. After the revisions in the items, Lawshe Technique was used to determine the content validity. 300 faculty members were administered the scale and a data set was obtained, which was analyzed for validity and reliability. Exploratory factor analysis (EFA) was used to reveal the construct validity of the scale, Cronbach's Alpha reliability coefficient, item-total score correlation and two-half test reliability methods were used to ensure the reliability of the scale, and lower 27%-upper 27% independent groups t-test was used for the discrimination of the scale. As a result of EFA, a 26-item, 3-factor structure emerged. This structure explains 59.647% of the total variance of the scale. Cronbach Alpha internal consistency coefficient for the reliability of the scale was found to be 0.952. It was observed that the item total correlation values were high and positive above 0.5 and the correlation values of all items were above 0.30, which is recommended as the lower limit. According to the results of the two-half test reliability analysis, the correlation coefficient between the equivalent halves was found to be 0.942. As a result of the t-test between the scores of the upper 27% and lower 27% groups in order to examine the discrimination of the scale items, it was found that the difference between the groups was significant at α=.000 level.
