A Review of Methods for Missing Data

This paper reviews methods for handling missing data in a research study. Many researchers use ad hoc methods such as complete case analysis, available case analysis (pairwise deletion), or single-value imputation. Though these methods are easily implemented, they require assumptions about the data that rarely hold in practice. Model-based methods such as maximum likelihood using the EM algorithm and multiple imputation hold more promise for dealing with difficulties caused by missing data. While model-based methods require specialized computer programs and assumptions about the nature of the missing data, these methods are appropriate for a wider range of situations than the more commonly used ad hoc methods. The paper provides an illustration of the methods using data from an intervention study designed to increase students’ ability to control their asthma symptoms.     

Early identification and interventions for dyslexia: a contemporary view

This paper reviews current proposals concerning the definition of dyslexia and contrasts it with reading comprehension impairment. We then discuss methods for early identification and review evidence that teacher assessments and ratings may be valid screening tools. Finally, we argue that interventions should be theoretically motivated and evidence based. We conclude that early identification of children at risk of dyslexia followed by the implementation of intervention is a realistic aim for practitioners and policy‐makers.     

Culture and Technology: implications for multicultural teacher education

ABSTRACT

American classrooms are experiencing a rapid growth in cultural and ethnic diversity, as well as an increase in educational classroom computing. Because culture directly affects classroom organisation and classroom learning, teachers need to understand, incorporate, and support their students’ cultures. Furthermore, since educational computing is not culturally neutral, teachers in culturally diverse settings must integrate the computer culture, the classroom culture, and students’ learning preferences. To meet the need for culturally and technologically competent multicultural teachers, teacher education programs must first define both cultural competency and computer competency. After examining the relationship between culture and educational computing, the paper explores some essential components of cultural and technological competency for multicultural teachers. Finally, it indicates the need for further research on the interaction of culture and technology in the multicultural classroom.

媒体素养——大学生思想政治教育的必备课题

思想政治教育的目的是使大学生成为德智体美全面发展的人才.在新媒体环境下,大学生总体表示出理性的态度与行为,但处于思想活跃又缺乏主观能动性的他们,容易迷失自我,仅仅在德智体美方面进行思政教育,突显出一定的问题,他们的媒体素养较为缺乏,这给当代大学生思政教育带来了困难与挑战.故此在思政教育过程中应增加“媒体素养”这一内容,它既是思政教育的调味剂,又是一道独家美味佳肴,应在大学生思政教育中烹调好这道菜.     

高职院校学生人文阅读现状与培养对策研究

高职教育作为高等教育的重要组成部分,向社会培养了大批工作在生产第一线的高技能、复合型人才。但与此同时,高职院校毕业生综合素养较低的问题也呈现出来,主要表现在语言表达能力和逻辑思维能力不高,心理承受力和应变能力较差等问题。这与高职院校教育存在重专业、轻素质;重技能、轻人文的现象有着重要的关系。本文通过对三所高职院校调查问卷获取第一手资料,并依此提出提高高职院校学生人文阅读能力的对策,以期抛砖引玉,共同探索提升高职院校学生人文阅读的新方法。
