技术改造课程,技术改善学习——全国高校教育技术协作工作委员会第七届年会暨学术交流会（CETA7）综述

信息技术的高速发展为高校教师提供了新的教学方式,学生的学习方式也因此而改变,在课程和学习被改变的同时,教育在无形中就发生了变化。全国高等学校教育技术协作工作委员会第七届年会暨学术交流会（CETA7）于10月13日至14日在辽宁大连举行,大会以＂技术改造课程、技术改善学习＂为主题,围绕视频公开课建设、资源共享课建设、教师教学能力提升、教育新技术、教师专业发展、网络教学平台的深度应用等主题展开,与会者进行了较为深入地交流与探索。     

智能教学系统中的学习推理模型研究

将Agent技术引入智能教学系统(ITS)是当前ITS研究的重要方向之一,本文提出了一种改进的基于Agents的学习推理模型,在模型中引入了学生Agent,教学Agent,资源Agent,资源管理Agent,并对各Agent的基本功能进行描述,进一步明确了教学Agent的各项功能,该模型能更好的反映学生的学习状态和学习需求,更能满足个性化学习的需要。

Adverse childhood experiences and deleterious outcomes in adulthood: A consideration of the simultaneous role of genetic and environmental influences in two independent samples from the United States

BackgroundAdverse childhood experiences (ACEs) are a potent risk factor. Despite these findings, studies have also recognized the importance of considering additional sources of genetic and environmental influence that cluster within families.ObjectiveTo properly control for latent sources of genetic and within-family environmental influences and isolate the association between ACEs and the following outcomes in adulthood: physical health, depressive symptoms, educational attainment, income attainment, alcohol problems, and antisocial behavior.Participants and SettingTwo independent samples of twins and siblings from the United States: the Midlife Development in the United States (MIDUS) study (N = 862) and the National Longitudinal Study of Adolescent to Adult Health (Add Health; N = 3112).MethodsSibling comparison models, which control for latent sources of genetic and within-family environmental influences, were estimated to examine whether differential exposure to ACEs was associated with the examined outcomes.ResultsFamilies that experienced more adversity also experienced more deleterious outcomes. However, siblings that experienced more adversity were no more likely to experience deleterious outcomes than their co-siblings. However, greater exposure to ACEs was associated with increases in depressive symptoms (Add Health). Additional models revealed that the similarity between siblings from the same family stemmed from latent sources of within-family environmental influences not captured by traditional ACEs measures.ConclusionsConsidering genetic influences and additional latent sources of within-family influences is crucial in isolating the effects of ACEs. Currently employed ACEs measures may not adequately capture the full range of impactful sources of family-level environmental influence.     

Using students’ feedback for teacher education: measurement invariance across pre-service teacher-rated and student-rated aspects of quality of teaching

Comparing self-perceived quality of teaching to students’ perception can be used in higher education to improve the quality of teaching of pre-service teachers in teacher education. However, comparing these measurements from different perspectives is only meaningful if the same constructs are being measured. To shed light on this comparison’s meaningfulness, we scrutinised whether aspects of quality of teaching are measured in the same way across pre-service teachers and their students by means of measurement invariance analyses. To do so, 272 pre-service teachers in teacher education rated aspects of their quality of teaching, and were rated by their 4851 students. Measurement invariance across these perspectives was tested in multilevel structural equation models. Strong measurement invariance held for two aspects of quality of teaching; for the third, one item lacked weak measurement invariance. Pre-service teachers perceived their quality of teaching lower than their students. In conclusion, aspects of quality of teaching can be compared across perspectives, and teacher education should encourage pre-service teachers to use students’ feedback as a valuable resource for improving their quality of teaching.

以工作过程为导向的高职校本教材的开发

工作过程导向模式是一种全新的职业教育模式,校本教材作为与之配套的教学材料,也应以工作过程为导向。探索以工作过程为导向的校本教材的开发。     

农村信息技术课中三分法教学模式的应用

由于农村高中的信息技术课地位差、课时少、学生水平参差不齐等原因,使得新课改下的教学举步维艰。三分法教学模式能为农村信息技术教师在新课改的道路上搭一段平缓的阶梯,它将课堂分为复习与提高、精讲与练习、评价与作业等3个阶段,每个阶段各占15分钟,既有效版面教师常常不知不觉中又回到传统的"满堂灌"方式上,又能使所学知识在课堂上得到充分的巩固提高。     

从中国留学生在英国的学习表现看我国教育存在的问题及对策

近年来,越来越多的中国学生选择在国外高校学习深造,中国学生在国际化教育背景下的表现彰显了现阶段我国教育中存在的问题。借鉴国外院校优秀的教育理念和模式,结合我国教育自身的特点,寻找解决教育问题的对策,是当前提高我国教学质量、加强学生素质培养的有效途径。
