This paper shows how the patterns of variation created in the teaching were critical in helping a class of Primary 3 students in Hong Kong to learn about the colour of light, so that the students attained conceptual rather than procedural knowledge. A ‘Learning Study’ approach was adopted, which is a Lesson Study grounded in a particular learning theory to improve teaching and learning. This study, based on the learning theory of Variation advanced by Marton and Booth, was premised on three types of variation: variation in students’ ways of experiencing what is to be taught/learnt (V1), variation in teachers’ ways of dealing with the ‘object of learning’ (V2), and the use of ‘pattern of variation’ as a guiding principle of pedagogical design to enhance students’ learning (V3). In planning the lesson, a conscious effort was made to create relevant patterns of variation, i.e. varying certain critical aspect(s) while keeping other aspects of the object of learning invariant in order to help students to discern those aspects. Comparison between the results of the pre- and post-test shows that there was significant gain in the students’ learning outcomes with respect to the intended object of learning. The findings contribute knowledge to how the Theory of Variation can be used in practice. It also illustrates how teachers can make use of this theoretical framework to analyze their own teaching and thereby, develop an analytical awareness of teaching and learning.  相似文献

信息时代中的青少年德育     

卢乃桂  王芳 《教育学报》2006,2(2):55-59

在华人社会,道德教育一直以来都是教育最基本的组成部分,因为培养有道德的人是教育的首要任务。道德教育的实施,其实是培植那些反映道德标准的价值观。然而,信息时代的出现及充斥在互联网上的大量信息,已改变了教育的方式,并向传统的道德教育发出挑战。在这一背景下,我们建议中国的教育工作者应寻求实践道德教育的新途径,以迎接网络世界的出现。崇高空洞的道德标准应让位给简洁易懂的观念,比如“尊重”。我们应该积极的去探索“网络世界”中的信息和观念,而不是一味的避免。有启发性和适切的道德教育应建基于儿童和青少年的发展需要和真正兴趣之上。华人社会的德育工作者,包括学校教师,家长,非正式教育的组织者,都应共同努力去了解虚拟的网络世界,并设计出可行的方法来适应新形势下的教育需要。  相似文献   

Effects of Alternated Basketball Competition on Perceived Competence in Adolescents with Intellectual Disabilities Over a Period of 13 Months: A research note     

Christophe Maïano  Grégory Ninot  Gérard Bruant  Jean Bilard 《International Journal of Disability, Development & Education》2002,49(4):413-420

The purpose of this study was to examine the effects of alternated (segregated and integrated) basketball competition on two domains of perceived competence and on general self-worth. Participants were 24 adolescent males with intellectual disabilities divided equally into three groups: (a) those involved in basketball in an alternated sport competition, (b) those involved in adapted physical activity, and (c) those who were sedentary. The experimental treatment lasted for 13 months. For the sport competition group this involved 2 hr of training each week and 12 competitive meets. We administered Harter's (1985) Self-Perception Profile for Children 13 times to determine changes in perceived competence and general self-worth. The results indicate no significant changes for the different groups in the two domains of perceived competence and in general self-worth over 13 months.  相似文献   

A discursive question: Supporting student-authored multiple choice questions through peer-learning software in non-STEMM disciplines     

Stephen Snow  Adriana Wilde  Paul Denny  m. c. schraefel 《British journal of educational technology : journal of the Council for Educational Technology》2019,50(4):1815-1830

Peer-learning that engages students in multiple choice question (MCQ) formulation promotes higher task engagement and deeper learning than simply answering MCQ’s in summative assessment. Yet presently, the literature detailing deployments of student-authored MCQ software is biased towards accounts from Science, Technology, Engineering, Maths and Medicine (STEMM) subjects, rather than discursive subjects or disciplines where content may contain fewer absolute facts and objective metrics and more nuance. We report on qualitative and quantitative findings from a semester-long deployment of a peer-learning software package (PeerWise) in a 140-student course on Interaction Design. PeerWise enables students to author, rate and comment upon their peers’ MCQ questions. The platform was enthusiastically adopted as a revision aid, yet overall question quality was poor and students expressed difficulty in translating the discursive nature of the course content into MCQs with only one correct answer. In addressing these shortcomings, this paper offers specific recommendations to instructors of more discursive subjects using student-led MCQ authoring platforms, and further, how platforms such as PeerWise may be adapted to better suit disciplines characterised by discursive content. We propose alternative approaches to moderation and two suggestions for potential amendments to the software itself.  相似文献   

Cognitive-linguistic profiles of Chinese typical-functioning adolescent dyslexics and high-functioning dyslexics

Dyslexia is a developmental disability affecting the acquisition of reading and writing skills, and its developmental nature makes longitudinal research of great importance. This study therefore investigated the cognitive-linguistic profiles of the typical-functioning dyslexics and high-functioning dyslexics with longitudinal cohorts of Chinese-speaking adolescents diagnosed with childhood dyslexia. These two dyslexic groups of fifty students (with 25 typical-functioning dyslexics) were assessed in Grade 2 (Time 1) and in Grade 8 (Time 2), whereas 25 typically developing controls were assessed at Time 2. Students were administered measures of phonological awareness, morphological skills, visual-orthographic knowledge, rapid naming, verbal working memory, and literacy skills. Results showed that, at Time 2, both dyslexic groups performed less well than the control group on most of the measures. Deficits in rapid naming were particularly salient in both dyslexic groups. Comparing the two dyslexic groups, the typical-functioning dyslexics had more multiple deficits than the high-functioning dyslexics. Findings highlight the importance of rapid naming deficits as potential universal causes of dyslexia and the utility of targeting visual-orthographic knowledge and morphological skills in supporting the development of dyslexic adolescents.  相似文献   

Identification of learning styles online by observing learners' browsing behaviour through a neural network     

Jia-Jiunn Lo  Pai-Chuan Shu 《British journal of educational technology : journal of the Council for Educational Technology》2005,36(1):43-55

Identification of individual learning style is important when developing adaptive educational hypermedia systems. Current systems ask learners to complete questionnaires to identify their learning styles, which might not be appropriate in some contexts. The goal of this research is to identify the learner's learning style by simply observing his/her browsing behaviour without asking the learner to answer any questions or filling out any form. It is implemented through a multi‐layer feed forward neural network (MLFF). Browsing behaviour, in this research, includes three factors, the use of embedded support devices (ESDs), the selection of link types, and the navigation between visited/unvisited nodes. The experiment results showed the proposed model performed well in identifying learning styles. Link type is the dominant factor and Time shift may not be a major factor in the identification of learning styles. Because of the fast execution property of neural networks and identification of learning styles online, it is possible to incorporate learning styles into online adaptive educational web‐based systems.  相似文献   

Recent Changes to Reference Services in Academic Libraries and Their Relationship to Perceived Quality: Results of a National Survey     

Jason Coleman  Melissa N. Mallon  Leo Lo 《图书馆管理杂志》2013,53(6):673-696

ABSTRACT

A national survey of academic librarians was conducted to examine relationships among reference service staffing changes, reference service innovations, adoption of reference technology, library type and size, and service quality. Analysis of the 606 response sets reveals trends toward reduced use of librarians and increased use of student staff at in-person service points, widespread increases in appointment-based and self-service reference, intensive efforts to reduce demand for reference by improving library instruction, and general improvements in reference service quality. Factors strongly associated with decreases or increases in quality are discussed in detail and implications for reference managers are provided.  相似文献   

Exposure of Taiwanese adolescents to pornographic media and its impact on sexual attitudes and behaviour     

Ven‐hwei Lo  Edward Neilan  Mine‐ping Sun  Shoung‐Inn Chiang 《亚洲交流杂志》2013,23(1):50-71

This article examines the use of pornographic media by Taiwanese high school students, and explores the effects of exposure to such on their attitudes and behaviour in terms of sexual permissiveness.

The results of this research indicate that more than 90 per cent of the students interviewed had at least some exposure to a variety of pornography, with males reporting significantly higher exposure frequencies than females. The results also show that exposure to pornographic media has significant effects on high school students’ sexual permissiveness and nonexclusive sexual attitudes and behaviour.  相似文献   

Do Consonant Sonority and Status Influence Syllable-Based Segmentation Strategies in a Visual Letter Detection Task? Developmental Evidence in French Children     

Norbert Maïonchi-Pino  Bruno de Cara  Jean Écalle  Annie Magnan 《Scientific Studies of Reading》2013,17(6):550-562

This article queries whether consonant sonority (sonorant vs. obstruent) and status (coda vs. onset) within intervocalic clusters influence syllable-based segmentation strategies. We used a modified version of the illusory conjunction paradigm to test whether French beginning, intermediate, and advanced readers were sensitive to an optimal “sonorant coda–obstruent onset” sonority profile within the syllable boundaries as a cue for a syllable-based segmentation. Data showed that children used a syllable-based segmentation that improved with reading skills and age. The results are discussed to support that the visual letter detection within pseudowords primarily and early relies on acoustic-phonetic cues within the syllable boundaries, whereas the syllable effect seems to be developmentally constrained by reading skills and age.  相似文献
