Self‐reported measures are an easy, time‐efficient, and low‐cost way to collect research data compared to other assessment methods. They are, however, characterized by several limitations regarding the quality and the clarity of the data they produce, especially when they are implemented in education. The main purpose of the current study was to use a method called discrete choice modeling (DCM) in education, in order to develop a self‐reported instrument that will reduce the bias for socially desirable responses and to assess teachers’ practices in physical activity. DCM method has the ability to overcome the respondents’ tendency to answer in a socially desirable way. A nationally representative sample of 531 Greek early educators participated in this study and were administered a self‐assessment questionnaire based on DCM. Results showed that the DCM based newly developed instrument manages to assess effectively educators’ practices and provided evidence of the applicability of the method in education. Further implications and future recommendations regarding the effective application of DCM in education are discussed.  相似文献

In this ITEMS module, we introduce the generalized deterministic inputs, noisy “and” gate (G‐DINA) model, which is a general framework for specifying, estimating, and evaluating a wide variety of cognitive diagnosis models. The module contains a nontechnical introduction to diagnostic measurement, an introductory overview of the G‐DINA model, as well as common special cases, and a review of model‐data fit evaluation practices within this framework. We use the flexible GDINA R package, which is available for free within the R environment and provides a user‐friendly graphical interface in addition to the code‐driven layer. The digital module also contains videos of worked examples, solutions to data activity questions, curated resources, a glossary, and quizzes with diagnostic feedback.  相似文献

我国优秀标枪运动员陈奇投掷步技术特点分析   总被引:6,自引:0,他引:6  
采用高速摄像、录像解析及比较分析方法,对我国优秀标枪运动员陈奇投掷步相关运动学参数进行比较分析。结果发现陈奇投掷步的技术特点:助跑距离较长、助跑速度较快,第二交叉步前后速度损失同投掷成绩呈负相关;第一交叉步前后身体重心速度的增加幅度同交叉步前后躯干后倾角变化量呈负相关,第二交叉步前后身体重心速度的损失幅度同交叉步前后躯干后倾角变化量呈负相关;最后一步前后身体重心水平速度的损失幅度同躯干后倾角变化量呈正相关。  相似文献

Bast fibres have been commonly used as a textile material in Northern Europe since Neolithic times. However, the process of identifying the different species has been problematic, and many important questions related to their cultural history are still unanswered. For example, a modified Herzog test and the presence of calcium oxalate crystals have both been used in identification. In order to generate more reliable results, further research and advancement in multi-methodological methods is required. This paper introduces a combination of methods which can be used to identify and distinguish flax (Linum usitatissimum), hemp (Cannabis sativa), and stinging nettle (Urtica dioica). The research material consisted of reference fibres and 25 fibre samples obtained from 12 textiles assumed to be made of nettle. The textiles were from the Finno-Ugric and Historical Collections of The National Museum of Finland. The fibre samples were studied by observing the surface characteristics and cross sections with transmitted light microscopy, and by using a modified Herzog test with polarized light, in order to identify the distinguishable features in their morphological structures. The study showed that five out of 25 samples were cotton, 16 nettle, one flax, and one hemp. Findings from two samples were inconsistent. The results show that it is possible to distinguish common north European bast fibres from each other by using a combination of microscopic methods. Furthermore, by utilizing these combined methods, new and more reliable information could be obtained from historical ethnographic textiles, which creates new vistas for the interpretation of their cultural history.  相似文献

This study examines how the Early Years Educators at Play (EYEPlay) professional development (PD) programme supported inclusive learning settings for all children, including English language learners and students with disabilities. The EYEPlay PD model is a year‐long programme that integrates drama strategies into literacy practices within real‐classroom contexts. Inclusive education refers to ensuring equal opportunities to access and participation in learning activities for all students. Cultural‐historical activity theory was used to understand and unpack the drama practices. Twelve semi‐structured focus group interviews were conducted with 19 preschool teachers. The data were analysed via constant‐comparative and interpretive methods. The study findings showed that EYEPlay PD practices enhanced inclusive learning settings for diverse groups of students by increasing access and expanding opportunities to learn, and supporting a positive learning environment.  相似文献

This article reports historical research which sought to understand the present‐day post‐secondary art curriculum through analysing its history in terms of changes in conceptions of art. It found that there have been six distinctive curricula: Apprentice, Academic, Formalist, Expressive, Conceptual and Professional. As a new curriculum has been introduced, it has co‐existed with much contained in a previous one. Most of the curriculum changes have taken place in the past 65 years. During this time, there has been a massive expansion in the education of artists and at the same time art schools accommodated first modernism and then post‐Duchampian aesthetics. A conclusion is that this has made for a very crowded curriculum. Moreover, despite there being an ever increasing choice of things a student might learn, it appears that there is nothing which all students have to learn. It can be problematic that one part of the curriculum is in contradiction to another part, and moreover this lack of a core raises fundamental, ontological questions about what art as a discipline is.  相似文献
