Discrete Choice Modeling in Education: An Innovative Method to Assess Teaching Practices

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.     

Digital Module 05: Diagnostic Measurement—The G‐DINA Framework https://ncme.elevate.commpartners.com

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.     

Diversity Literary Awards: A Tool for Assessing an Academic Library’s Collection

Abstract

Diversity literary awards and other sources were used to create a list of high-quality titles written by and about underrepresented groups. This list was used to assess the diversity and inclusiveness of the library collections of a land-grant university in the Pacific Northwest and compare it to peer institutions. Gaps in the collection and acquisition processes were identified and will be used to improve the processes to increase the number of diverse titles added to the library’s collections.     

Analyzing Food Science Research for Publishing Characteristics as a Model for Understanding the Needs of Researchers

Abstract

This paper provides a methodology to study the characteristics of the research output from a university department. The faculty publications and their cited references over a 10-year period were used as the basis for this study to identify their publishing patterns and the types of material they are publishing; a core set of journals and other resources they are publishing in and citing over this period; the characteristics of the journals in which they publish and cite; the degree of openness of their publications and their citation advantage; and the age of resources that are referenced.

从当前中小学体育教学现状看高校体育教育专业的教学改革

在新的历史时期，研究中小学校体育教学现状对于高等体育教育专业的教学改革十分必要。本主要采用问卷调查和献分析等方法对我国16个省、直辖市、自治区的241所中小学校进行问卷调查和分析，发现：当前中小学校体育教师的教学工作负担过重，科研的整体水平偏低，法律意识淡薄等不利因素；同时提出：在现阶段的高等体育教学中，应当加强对学生科研能力的培养，技术教学要突出“多能一专”的教学思想，并建议有关部门关注体育教师的“减负”问题。

不同技术类型背越式跳高摆动动作对起跳效果的影响

通过采用不同研究模型对我国优秀男子不同技术类型背越式跳高运动员在起跳时摆动动作效果进行定量分析，探讨我国优秀男子不同技术类型背越式跳高运动员摆动动作对起跳效果的影响。结果表明：我国优秀男子背越式跳高运动员摆动效果约占50％，且摆动效果的大小与技术类型无关，与高度的增加没有线性相关。但当高度增加到本人最好成绩时，摆动作用达到最大值。选用中国男性青年模型与扎齐奥尔斯基模型对背越式跳高技术进行研究，结果没有显差异性。
