信息技术与课程整合的教学模式研究之二——“传递—接受”教学模式

该文是系统研究"信息技术与课程整合教学模式"系列研究论文的第二篇。这组系列研究论文对信息技术与课程整合实施过程中广大教师必须面对的重要问题——"对信息技术环境下教学模式的内涵与特征应如何正确认识、以及对这类教学模式应如何有效实施"作了较深入的探讨;该文则着重对课内整合模式中的主要代表之一"传递—接受教学模式"进行研究,并从该模式的产生背景、内涵与特征、实施步骤及实施案例等几个方面做出比较深入的阐述。     

Comparison of retention and extinction of a visual discrimination as an index of forgetting in mice

The retention and extinction of a visual discrimination was examined in BALB/c mice. The mice were trained to perform a go/no-go discrimination task in parallel runways. Initial training resulted in an intermediate level of performance. Testing consisted of an additional session using either retention (Experiment 1) or extinction (Experiment 2) at one of five time intervals between 1 and 30 days. It was found in Experiment 1 that forgetting progressively increased over intervals of between 14 and 30 days. In Experiment 2, extinction testing induced more impairment of performance, so that forgetting occurred earlier relative to retention testing in Experiment 1. However, in both experiments, the measure of performance by a discrimination ratio revealed the same amount of forgetting when the training-test interval was 30 days. These results define the forgetting curve for such a discrimination by mice. They are discussed in terms of possible factors involved in forgetting.     

图形—背景理论解读英语中动结构的语义基础

从认知语言学的视角探讨英语中动结构的认知语义基础,运用“图形—背景理论”对中动结构及其相应的被动语态进行比较分析。本文认为两种句型结构虽都表达了被动意义,但由于某种原因1)即使图形相同,充当的角色也不同;2)背景不同,凸显程度及其所起作用亦不同;3)后景的凸显程度也不同这三种情形而导致两种句型结构的语义并不相同。

Compatibility and Complementarity of Classroom Ecology and Didactique Research Perspectives in Physical Education

ABSTRACT

A large diversity of theoretical frameworks exists in the physical education literature. This article focuses on two of those frameworks to examine their compatibility and their complementarity. The classroom ecology paradigm concentrates on the balance between three task systems, two vectors, and programs of actions proposed by the physical education teacher and negotiated by students. The didactique research program studies the teaching and learning processes using the concepts of didactic contract and didactic milieu that focus on how the knowledge content emerges within teacher and students’ joint action. The article underlines the complementarity and the compatibility of the two frameworks when analyzing teaching and learning in physical education. It argues that the gray areas left by the classroom ecology paradigm could be filled with the insights of the didactique research program. A concise example of how the two frameworks have already been utilized is presented.     

塔与灯的真实--论《到灯塔去》中灯塔的象征意义

伍尔夫的《到灯塔去》富含各类象征意象。其中，灯塔是最重要的象征意义复合体，是拉姆齐夫妇的形象代表，象征着理智与情感、现实与理想的统一。同时，伍尔夫也借这一“客观对应物”表达了她对世界存在本质的看法。战后的灯塔之行反映了伍尔夫在困顿中的良好愿望，这既是对世界本体的确认，也是对人物自我求证的肯定。

部队院校开放性电学实验教学实践

随着信息化技术的快速发展,现代社会对于高校学员的综合素质要求越来越高,实验教学也需要做相应的调整以适应需求。在电学实验中开设"智能灯"项目的开放实验就是基于此种目的,在模拟电路实验和数字电路实验课程中锻炼学员解决问题、动手实践的能力,再结合新的开放实验考核方式对学员的综合素质做出评价,有利于学员创新思维、个性发展的培养。     

Anti-bullying procedures for schools in Ireland: principals’ responses and perceptions

The role of the principal is imperative in creating a school climate that nurtures differences and equality at the same time. Policy and legislation in Ireland dictates the responsibility of school principals in preventing and intervening in issues relating to bullying. The current research investigates the extent to which principals consider the impact of bullying on their students and the strategies they take to combat it in their schools. We consider how principals respond to bullying and what supports they feel are missing for them to adhere to relevant policy. A sample of 918 principals from a range of schools across Ireland completed an online survey. The results demonstrated some positive actions by principals such as the provision of anti-bullying policies. However, they also document areas that need more action such as increased access to counsellors and appointing a specific staff member to deal with and tackle bullying in each school. Guidance from the Department of Education and Skills in Ireland on the development and provision of an anti-bullying programme is called for. Results are discussed in light of the current Anti-Bullying Procedures established by the Department of Education and Skills and the Action Plan for Bullying 2013.
