Abstract

The development of survey items includes the preparing and validating the items. A construct validity and reliability are two important concepts in survey research that are used to assess the quality of survey items. This study was conducted to generate on the construct validity process of the survey items in heutagogy elements specifically for vocational learning. Items have been developed based on relevant literature and the context of vocational education in particular leads to readiness for employment. Therefore, to go through the process of validity and reliability of the items, this study involved 100 students from Vocational Colleges to response the survey items. There are 71 items in a set of questionnaires with six elements consists of Exploring, Collaborating, Relationship, Creating, Reflection and Sharing. The data was analysed based on Rasch Model as statistical measurement model that can be used to assess the validity and reliability of research instruments. The construct validity was examined by analysing the point-measure correlation index, infit, and outfit values; meanwhile, the reliability was examined by analysing the item reliability index. The results have shown that the findings of the analysis found seven items dropped because the items did not meet the requirements of the established analysis. By analysing the data collected from the questionnaire, the final instrument shows a total of 64 items suitable for measuring six elements of heutagogy. The Rasch Model differs from other measurement models in reliability assessment by focusing on one-dimensionality, assessing both person and item reliability, enabling item calibration, and providing fit statistics. Hence, this systematic approach may facilitate researcher to improve the items to produce the good quality of research instrument.
神学调查项目的开发与验证
调查项目的开发包括项目的准备和验证。构念效度和信度是调查研究中的两个重要概念,用于评价调查项目的质量。本研究旨在探讨职业学习学要素调查项目的建构效度过程。项目是根据有关文献和职业教育特别是为就业做好准备的背景拟订的。因此,为了对问卷进行效度和信度的检验,本研究选取了100名高职院校学生来回答问卷。一套问卷共有71个项目,包含探索、合作、关系、创造、反思和分享六个要素。数据分析基于Rasch模型作为统计测量模型,可以用来评估研究工具的效度和信度。通过分析点测量相关指数、infit和装备值来检验结构效度;同时,通过对项目信度指标的分析,对项目的信度进行了检验。结果表明,调查结果的分析发现七个项目下降,因为项目不符合既定的分析要求。通过分析从问卷中收集的数据,最终的仪器显示了64个项目,适用于测量六种元素的变异。Rasch模型与其他测量模型在可靠性评估方面的不同之处在于,它侧重于一维,评估个人和项目的可靠性,允许项目校准,并提供拟合统计。因此,这种系统的方法可以帮助研究者改进项目,以生产出高质量的研究仪器。
