广州市流动儿童社会适应性调查与思考     

李柏宁  熊少严 《现代教育论丛》2007,(5):27-31

选取广州市1200名流动儿童进行问卷调查,研究结果表明,目前广州市流动儿童的社会适应性总体处于良好发展水平,但也存在一些不容忽视的适应问题与障碍。目前存在的城乡二元制度是流动儿童社会适应性问题的根本性原因,促进城市流动儿童社会适应性发展应从两方面努力,当前尤其需要国家、政府以及流动儿童家庭、学校与社会等多方面协同参与,从制度、文化层面形成流动儿童社会适应与融合的良性发展机制。  相似文献

Understanding and supporting the use of feedback from mobile applications in the learning of vocabulary among young adolescent learners     

《Studies in Educational Evaluation》2023

Understanding how young adolescent learners interact with mobile vocabulary learning applications can aid them in becoming more engaged with the information and feedback they are receiving. Inspired by the literature on learner-oriented feedback practice, this study asked two research questions: 1) what kind of feedback from the mobile apps can predict their learning experience, and 2) what features are useful in the support of self-assessment practice? Both survey data (n = 259) and interview data (n = 12) were collected from students at a junior school in southern China. Quantitative analysis suggests that high levels of satisfaction and perceived usefulness are associated with two factors: 1) visualizing the learning gaps with reference to external standardized tests and curricula, and 2) encouraging independent rather than social learning strategies. The qualitative data identified four main features or principles which may support young adolescent learners’ use of apps for self-assessment practice: 1) explicit links to curricula and tests; 2) immediate feedback on answers and learning strategies with more similar tasks; 3) maintaining relationships with teachers and peers, and 4) emotional support. Implications include the integration of quick automatic feedback to app users, clear alignment of self-assessment tasks with national curriculum and tests, and stronger emotional and cognitive support from both peers and instructors.  相似文献   

“Was that interesting?” & “Does it matter?”: The implications of on-task learning experiences     

《Studies in Educational Evaluation》2023

Interest is a critical fuel for and outcome of learning. Building on and refocusing the Four-Phase Model of interest development, this study provides a window into the ecology of the learning experience and interest it generates. This research uses a novel mobile assessment platform to test learning experiences in three university courses (Organic chemistry, biochemistry, and introduction to physics for non-majors) and pilots a micro-analytic approach to capturing these experiences during lectures/tutorials. Students' interest in tasks, a single class, and the domain of study were collected with short surveys through an online mobile platform during class, immediately following task experiences. Latent variance-based modelling suggested strong forward connections between interest in most tasks. The connections between prior knowledge and interest with a future interest in course tasks varied strongly and were dependent on the nature of the tasks. The nuance of these connections and their implications for mobile assessment are discussed.  相似文献   

法国校园禁用手机法案的成效与争议     

杨光富  陈宏友 《比较教育研究》2020,(1):33-38

2018年法国国会表决通过了《3~15岁学生在校园内禁止使用手机的法案》,其实早在2010年法国就出台过相关法案,但本次禁机令要求更加严格。目前,法国已超过90%的学生拥有手机,但不当使用给学生带来了手机上瘾症、网络欺凌、学业成绩下降等问题。由于上述原因以及欧洲委员会手机禁令的倡导,法国最终颁布了该法案。法案实施后,学生已经逐渐适应,课堂纪律得到很大的改善,学生课后相互交流和运动的机会大大提高。不过,在实践中也遇到了手机如何存放与管理、家长与孩子如何及时联系等问题。  相似文献
