Synergizing geriatric research and education in an allied health profession with an older adult community advisory board: development and process outcomes

ABSTRACT

Community advisory boards (CABs) have been used to improve research outcomes involving specific communities and populations, including older adults. There is potential to synergize the use of CABs to encompass both research activities and the education of healthcare professionals to help meet increasing demands for a geriatric healthcare workforce in aging populations worldwide. We describe the development and process outcomes of a CAB that synergizes geriatric research and education of students in an allied health profession (occupational therapy). Implementation costs from June 2017–June 2019 were recorded. In-depth interviews were conducted with CAB participants, who were community-dwelling older adults living in St. Louis, Missouri, United States. Interview data were analyzed using a constant comparison method based on a grounded theory approach. Themes were derived regarding barriers, facilitators, and benefits of CAB participation for older adults. Fourteen older adults (aged 65 and over) were initially recruited. The total direct cost of CAB implementation was 4050 United States Dollars over two years. Barriers to CAB participation for older adults included unexpected schedule conflicts due to illness and lack of understanding of the research process, while facilitators included accessible meeting spaces, staff support, flexible participation options, and financial support (e.g., transportation). Perceived benefits of CAB participation included gains in social capital, more positive views of research, and social connectedness. Key lessons learned are described and can be used to inform a novel approach to developing and implementing CABs to improve outcomes of geriatric research and education.     

一种现代的民族浪漫主义情怀——对杨斌作品的一种解读

对本土民族文化的再现始终是画家杨斌所追求的不变主题,他把民族的欢乐,民族的美用独特的绘画语言展现在人们面前,这既表明了画家对待民族文化的一种立场,也多少改变了观者对待生命存在的态度。     

校长社会资本对农村普通高中教育资源配置的影响

高中教育是衔接义务教育和高等教育的重要环节.本文通过对西部农村高中学校的调查发现,高中学校校长所拥有社会资本的质量和数量与学校资源的获得和多少有显著关系,即拥有较多社会资本的校长,学校获得的资源相对也较多.因此,学校可以通过增加校长的社会资本积累,提高校长获取资源的能力,从而为学校争取更多的资源,解决高中教育资源紧缺的问题.同时,教育主管部门对不同学校安排不同社会资本拥有量的校长,也在一定程度上决定了学校之间资源配置的差异性.     

放大背景:解决高考现实问题的关键

建构主义认知灵活性理论的教学实践——小学语文教师职前教育实践探微

作为教育界的一种新的认识论和学习理论,建构主义对传统的教学观念提出了尖锐的批评,对学习和教学作出了新的解释。认知灵活性理论是建构主义的一支,它反对传统教学机械地对知识做预先限定,让学生被动地接受;同时也反对极端建构主义只强调学习中的非结构的一方面,忽视概念的重要性。它主张,一方面要提供建构理解所需的基础．同时又要留给学生广阔的建构的空间,让他们针对具体情境采用适当的策略。本文主要阐述建构主义的认知灵活性理论在高等师范教育专业课《小学语文教学论》教学中的作用及实施策略。     

Using Natural Language Processing to Predict Item Response Times and Improve Test Construction

In this article, it is shown how item text can be represented by (a) 113 features quantifying the text's linguistic characteristics, (b) 16 measures of the extent to which an information‐retrieval‐based automatic question‐answering system finds an item challenging, and (c) through dense word representations (word embeddings). Using a random forests algorithm, these data then are used to train a prediction model for item response times and predicted response times then are used to assemble test forms. Using empirical data from the United States Medical Licensing Examination, we show that timing demands are more consistent across these specially assembled forms than across forms comprising randomly‐selected items. Because an exam's timing conditions affect examinee performance, this result has implications for exam fairness whenever examinees are compared with each other or against a common standard.     

《紫藤花开》教学案例
