This study investigated teacher-student relationships from the teachers' point of view at Perth metropolitan schools in Western Australia. The study identified three key social and emotional aspects that affect teacher-student relationships, namely, Connectedness, Availability and Communication. Data were collected by questionnaire (N = 139) with stem-items answered in three perspectives: (1) Idealistic: this is what I would like to happen; (2) Capability: this is what I am capable of; and (3) Behaviour: this is what actually happens, using four ordered response categories: not at all (score 1), some of the time (score 2), most of the time (score 3), and almost always (score 4). Data were analysed with a Rasch measurement model and a uni-dimensional, linear scale with 24 items, ordered from easy to hard, was created. The data were shown to be highly reliable, so that valid inferences could be made from the scale. The Person Separation Index (akin to a reliability index) was 0.93; there was good global teacher and item fit to the measurement model; there was good item fit; the targeting of the item difficulties against the teacher measures was good, and the response categories were answered consistently and logically. Teachers said that the ideal items were all easier than their corresponding capability items which were in turn easier than the behaviour items (where the items fitted the model), as conceptualized. The easiest ideal items were: I like this child and This child and I get along well together. The hardest ideal item (but still easy) was: I am available for this child. The easiest behaviour item (but still hard) was: This child and I get along well together. The hardest behaviour item (and very hard) was: I am interested to learn about this child's personal thoughts, feelings and experiences. The difficulties of the items supported the conceptual structure of the variable.
本研究从教师的角度调查了西澳大利亚州珀斯市都会区学校中的师生关系。该研究确定了影响师生关系的三个关键社会和情感方面,即联系性、可及性和沟通。通过问卷调查收集数据(N = 139),主干项目从三个角度作答:(1)理想状态:这是我希望发生的情况;(2)能力:这是我能够做到的;(3)行为:这是实际发生的情况,使用四个有序的回答类别:完全不(得分1)、有时(得分2)、大部分时间(得分3)和几乎总是(得分4)。使用Rasch测量模型对数据进行分析,并创建了一个由24个项目组成的单维线性量表,项目按从易到难排序。结果表明数据具有高度可靠性,因此可以从该量表中得出有效的推论。人员分离指数(类似于可靠性指数)为0.93;教师和项目与测量模型的整体拟合度良好;项目拟合良好;项目难度与教师测量指标的匹配度良好,回答类别一致且符合逻辑。教师表示,理想项目都比相应的能力项目更容易,而能力项目又比行为项目更容易(在项目符合模型的情况下),这与概念化一致。最容易的理想项目是:我喜欢这个孩子和这个孩子与我相处融洽。最难的理想项目(但仍然容易)是:我随时为这个孩子提供帮助。最容易的行为项目(但仍然困难)是:这个孩子与我相处融洽。最难的行为项目(非常困难)是:我有兴趣了解这个孩子的个人想法、感受和经历。项目的难度支持了该变量的概念结构。
