介绍绝缘体变为导体的实验两则

“导体和绝缘体之间没有绝对的界限,在一定的条件下绝缘体也可以变成导体。一般条件下不导电的玻璃,当温度升高到一定程度时也会变成导体”。按照课本的要求,玻璃球作实验材料有一定缺陷。可以用废小灯泡、或盐水溶液来替代玻璃球来做实验,其结果是,材料易得,操作简便。效果更好。

Aligning Components of Recognition and Response and Response to Intervention to Improve Transition to Primary School

Children face numerous transitions throughout their school careers. Research has demonstrated that early transitions can positively or negatively impact future school performance. Establishing effective models to ensure carryover of instructional strategies and interventions into early elementary school can increase the likelihood children will have a smooth transition to kindergarten from preschool. Response and Recognition (R&R) is a framework for delivering a continuum of instructional strategies and interventions to meet children’s needs at the preschool level. Response to Intervention (RtI) is a framework for implementing a continuum of instructional strategies and interventions to meet children’s needs at the K-12 level. The purpose of this paper is to outline the similarities and differences between the R&R and RtI frameworks and to provide recommendations of ways the two frameworks can be used to ensure a smooth transition into primary school.

Learning to manage and managing to learn

In this paper Fiona Reeve, Jim Gallacher and Terry Mayes of Glasgow Caledonian University, bring together two current themes in higher education, work‐based learning and the use of new technology in teaching and learning. The paper begins to explore their interaction by examining the ways in which new technology can help to overcome some of the barriers which exist to work‐based learning. To begin this analysis a general model of a WWW‐based learning resource is described which has relevance for a range of open learning contexts. A central aspect of this model is the use of communication technologies to promote the creation of learning dialogues. The way in which this general model might be applied to work‐based learning is then examined. Having suggested that such a model has much to offer work‐based learning, some of the constraints which might be encountered on implementation are then identified. Finally, the authors conclude that it is in promoting more and better forms of communication that new technology can contribute towards work‐based learning practice.     

Accentuate the Negative to Latch onto the Affirmative (How to Save Mockingbirds)

Role play is a potent, widely employed technique in the teaching of controversial issues. Attitude modification is often cited as a major reason for using role play. But how can we expect attitudes to change if students, either through teacher accident or their own design, are allocated roles which reinforce attitudes with which they already identify? One possible remedy is to organise groups so that students are required to identify closely with value positions and attitudes with which they may not sympathise. The purpose of this paper is to outline a simple values clarification technique which can be used to assess students’ attitudes towards a controversial issue. Once this assessment has been completed, its results can be used for group selection. Subsequently the same technique can be used to assess the degree of attitude change. The approach outlined has the virtue of being a pedagogical technique which can also be used for group differentiation, summative evaluation and research. This approach will be illustrated by referring to the study of a controversial issue in Scotland by fourth year B.Ed. (Primary) students from Moray House Institute. Theoretical questions about how role play contributes to attitude change are also examined in the paper.

高校选留辅导员队伍建设现状及优化路径

选留辅导员是高校辅导员队伍中的一个特殊群体,其“来自学生、服务学生、回归学生”特点使其成为大学生群体“主对象”的知心人、日常思政教育“主阵地”的排头兵、辅导员队伍“主力军”的蓄水池。在辅导员专业化、职业化建设的大背景下,应该对选留辅导员队伍给予足够重视,从业务指导、工作机制、激励机制、职业规划等多方面优化设计。     

Lessons to be learned

The evaluative and reflective papers in this special issue of Education and Information Technologies show some interesting types of assistance information technology (IT) can provide to those who manage classrooms and educational organizations. Most of the papers are based on longitudinal research confirming the value of the applications of the IT presented. The papers strongly support the influence of the variable groups included in Fig. 1 in the introductory paper, and further comparison with the analysis framework can draw out inferences on what factors are of particular importance for successful implementation. We can conclude that, although the original framework was designed for more institutional level IT management implementations, it can additionally provide a guiding framework for evaluating the impact of IT on the wide variety of managing roles within the classroom, and should even provide a guiding and evaluative tool for a more virtual environment of the future

How to assess for improvement of learning

This review summarizes and builds on a seminar about assessment of student learning in higher education. Assessment can be looked upon as simply something that has to be done at the end of a course. During the course of discussions at the seminar the participants became more aware of how assessment can have an impact on learning. This means that assessment can be used as a means to improve learning. This realization is not a new one, but it is highlighted here in a more coherent and concise way than usual. Many alternative methods of assessment are possible. Some instructional design rules will be presented here for designing assessment sessions in such a way that learning can be improved. When designing an assessment method, one can be guided by the following considerations. The content of assessment should be chosen in accordance with the learning outcomes one hopes to achieve. The organization of assessment can be designed in such a way that the desired learning process is promoted. The outcome of assessment can provide feedback to many of the stakeholders: to the students on their learning process; to the faculty on its outcomes; and to the teacher by pointing out the following steps to be taken in improving assessment, learning and teaching.     

正确认识内部审计

正确认识内部审计有利于充分发挥内部审计作用。内部审计本质上是一种管理服务活动,其职能是兴利防弊和价值增值,并非专为检查舞弊而进行。内部审计不同于外部审计和管理咨询,内部审计能实施风险管理,为实现组织目标服务。
