新课程中的微积分及其教育价值

随着新一轮数学课程改革的进行,微积分再一次走进中学数学.微积分课程的教育价值主要有:增强了高中数学的严密性,优化了解题过程、扩展了研究范围,培养了学生解决实际问题的能力,发展了学生的数学思维能力,提高了学生的数学文化素养.要实现微积分的教育价值,需要兼顾不同层次学生对微积分的求知需求,把握高中微积分与大学微积分不同的尺度定位,防止微积分方法对高中基础知识的消极影响.

班主任如何强化小学生的德育教育

德育教育工作是一门知识面广,内容丰富、高深,并具有与时俱进特点的科学,要做好学校的德育工作,必须下苦功,必须掌握一定的德育理论知识,这是做好德育工作的前提。班级主任处在德育工作的第一线,是德育工作队伍的基本力量,他们教育管理水平的高低关乎学校德育工作的成败。作为德育工作者的职业形象是他在完成教育工作任务时,在学校以及在社会中承担的职业作用和表现。其自身形象对于学生的发展具有强烈的外在的示范性与内在的感染性。德育工作者的教育魅力,首先源于他做人的楷模,教师的仪表、工作作风、言谈举止和良好习惯,都是其良好素质的外化,同时也是影响学生形成良好素质的动力。     

试谈小学生写作能力培养

小学生的作文实质是练习用笔来说话。在学生已经学会或基本学会了用口语的基础上,要让学生学会用笔来说话,实现口头到笔头的转化,把写变成了一种由内到外的自由倾吐,使学生对于写话有兴趣,乐于把自己的所见、所闻、所思、所感毫无拘束地写下来,从而形成一种写作主体,写自己的自得之见,抒自己的自然之情,用自己的自由之笔,写自己的自在之趣的思想境界,这样就从心底里排除了＂作文难＂的障碍,减轻了学生的心灵压力,有利于提高作文教学的效益,让学生把所见、所闻、所感,尤其是最受感动的,印象最深的,不拘字数地写出来,这样就能培养学生作文的兴趣。学生写作文,感到最难的则是无话可写。为解决此难题,我在语文教学中提出了三点弥补方法,即多读书、多积累、多练。

School engagement and rights‐respecting schools

Disengagement in school is associated with behavioral problems and decreased academic achievement. In contrast, pupils who are engaged in school develop the academic and social efficacies that underlie successful adulthood. Moreover, engagement promotes educational resilience. This study examines pupils’ self‐reported level of engagement in schools that are explicitly respecting of children’s rights compared with pupils in traditional schools. The Young Students’ Engagement in School Scale was developed and used with 1289 9‐ to 11‐year‐olds from 18 schools, six of which had fully implemented the Hampshire Education Authority’s Rights Respect and Responsibility (RRR) Initiative. Factor analysis indicated four dimensions of engagement: rights‐respecting climate; interpersonal harmony; academic orientation; and participation. Pupils in RRR schools had higher scores on all but the academic dimension. The findings suggest the potential of rights‐respecting schools in promoting engagement and the potential utility of the measure in identifying areas in which pupils’ engagement may need intervention.     

Teachers’ perspectives on 40 years of reform: the case of the Israeli junior high school

The purpose of this study is to trace junior high school teachers’ perspectives regarding the strengths and weaknesses of their type of school, and to glean more information concerning their preferable type of grade configuration. To this end, 25 teachers filled out an open questionnaire and six of them were further interviewed to provide more insight into the teachers’ responses. Surprisingly, most of the teachers tended to strongly support the 1–8 type elementary schools rather than the current situation of 1–6, 7–9, 10–12 in which they have ever worked. Theoretical and practical implications are suggested.     

Understanding Singaporean preschool teachers' beliefs about literacy development: Four different perspectives

Investigating teachers' beliefs may shed light on their activities in the classroom, and in turn, on the pedagogical process itself. It is, however, not easy to study teachers' beliefs empirically. Q-methodology has been used over several disciplines to systematically investigate individuals' points of view on a range of issues. A study involving Q-methodology was conducted in Singaporean preschools to investigate some teachers' perceptions of early literacy development and instruction. The study revealed four viewpoint groups among the 30 preschool teachers who participated in the study, and possible teacher characteristics that distinguish the viewpoints from each other. The results suggest that the differences in viewpoints are indicative of differences in cultural expectations held by various groups of teachers.     

Let the children have their say: children with special educational needs and their experiences of Physical Education – a review

This paper reviews literature examining the perspectives of children with special educational needs related to their experiences of Physical Education (PE). The extent to which literature addresses inclusion in PE was determined and emerging themes arising from consultation with children with special educational needs regarding PE were examined. Qualitative studies, concentrating on consultation with special educational needs children, were reviewed and six key themes were identified: children's experiences of PE; their experiences of PE teachers; discrimination by others; feelings of self‐doubt; barriers to inclusion; and empowerment and consultation. Findings indicate children with special educational needs enjoy PE when fully included; however, participation is restricted by discrimination, limited teacher training and material barriers to inclusion. Consequently, teacher training in special educational needs and the education of non‐disabled children about special educational needs requires extensive consideration.     

Researching the views of pupils with multiple and complex needs. Is it worth doing and whose interests are served by it?

Because of what are perceived by some as potential challenges it is still commonplace for research to fail to seek the opinions of pupils with multiple and complex needs. While many such pupils do have significant communication difficulties, along with other disabilities, which are undoubtedly a constraint, it is crucial in order to be inclusive, that methods of fostering pupil voice are sought. This piece of practitioner‐based research seeks to do this by focusing on the introduction of an aided communication system, Talking Mats? , for pupils with multiple and complex needs in a mainstream secondary school setting. The study highlights the strengths and weaknesses of the introduction of Talking Mats. The notion of ‘research’ with this group of pupils is considered and the key issues of reliability, validity and ethics discussed. The paper concludes by reflecting on the findings and gives a number of practical ideas for future practitioner researchers.
