Portfolios as ‘learning companions’ for children and a means to support and assess language learning in the primary school

This article explores the idea of portfolios as a way to collect evidence of pupils' learning and achievement in their language learning in the primary school. The emphasis is on portfolio work as an active and reflective process to underpin and support learning and to show evidence of achievement and progression. Pupil choice and reflexivity are essential in the process. The process can encourage learners to draw on their learning experiences across the curriculum. Whilst a means of providing evidence of learning, and for showcasing work pupils are proud of, portfolios are seen as central to and embedded in the day-to-day learning and underpinned by the principles of formative assessment. Designed to be used with other modes of assessment including the European Languages Portfolio, portfolios are in essence flexible, inclusive and a dynamic record of learning, achievement and potential for every learner. In this article, the use of portfolios from an early age as a means to promote development and learning and a way of assessing learning are inextricably linked. Teachers working to develop portfolio work, and some of their pupils, add their voices to the discussion of portfolio development towards an enhanced dialogic assessment culture.     

Portfolio assessment: direct from the classroom

Portfolios have been regarded as a means of personal self‐expression. This study reports on student real‐life experiences with portfolio assessment. The focus group comprised 150 freshmen (100 females) from a small campus of a tertiary educational institution. For two semesters (approximately 30 weeks), students engaged in numerous activities selected to encourage deep learning and understanding of mathematical concepts. Because students were not involved in the experiment, ecological validity was maximised, and observations may be regarded as fairly authentic and worthy of analysis. Generally, students reported learning much from portfolio assessment and felt an integral part of the assessment process. Portfolio assessment appeared to empower students and provide them with the self‐respect they desired. Future research could compare results from everyday observations with those from experiments.

谈幼儿教师专业成长档案袋

评价是幼儿教师专业成长过程中不可或缺的重要环节。幼儿教师专业成长档案袋评价是一种体现幼儿教师成长和发展过程性的评价。合理制作和利用教师专业成长档案袋,能激发教师自我反思、自我纵向比较,关注教师个别差异,从而有效促进教师专业发展。     

论教育评价中审美意蕴的开掘——以档案袋评价为例

审美就是人在他所创造的世界中直观自身。教育评价①中审美意蕴的开掘是指在评价中通过确证人的主体地位以及人的精神力量,充分调动学生的感性,使其在和谐自由的氛围下创造性地完成个体的全面发展。这一目标的实现,需要当代教育评价从理念、功能、方式等方面进行必要的改革。     

博客应用于实践教学中的策略

近年来,博客作为一种新兴的媒介,受到教育工作者的关注,并迅速应用到教学过程中。实践教学以其动手能力和创新能力的培养为目的,在实际实施中也有一些不足之处,如师生分离、评价体系不够完善等。充分利用博客的特点来弥补实践教学的不足,让博客成为辅助实践教学的得力工具。     

浅析档案袋评价法在幼儿园教育中存在的问题及对策

档案袋评价法作为一种新的教育评价方法,运用到我国幼儿园教育中存在以下一些问题,如加重教师负担;档案袋所搜集的内容可信度不高;对幼儿作品的搜集和选择存在盲目性;对档案袋中收集的幼儿作品缺少必要的说明;幼儿的参与度不够等。对此,我们给幼儿园以及幼儿园教师提出了一些可行性建议,使档案袋评价法能有效促进幼儿全面发展。     

Technology 2000

Abstract

This article describes a collaborative university-school district project for improving teaching and learning by using state-of-the-art educational technologies. The work resulted in the simultaneous improvement of P-12 education and teacher education. The article illustrates some of the important outcomes of a project known as Technology 2000, a collaborative effort between a university, a school district, and a business partner. Through using appropriate educational technologies, pre-service teachers, in cooperation with their supervising teachers in five classrooms at two school sites, engaged in the collaborative alignment of curriculum, instruction, and assessment to facilitate student achievement. The participants believe that the outcomes of this educational technology project have important implications for improving teaching and learning in other schools and teacher education settings.
