浅谈在物理教学中如何设计新课引入

新课引入对整个课堂教学有着至关重要的影响。大多数比较好的引入环节，一般都渗透有启发性、情景性、趣味性、实用性、参与性等多个因素。文章就这些因素在初中物理课引入环节中的运用作了阐述．     

阅读媒介会导致发展性阅读障碍吗——一项面向学龄儿童群体的实证研究

随着数字技术的发展,多元化阅读媒体影响着读者的阅读行为、阅读方法和阅读认知能力。本研究采用实验法,以学龄儿童为被试对象,对其纸质阅读与数字阅读的表现进行分析,探究阅读媒介对各项阅读认知能力产生的影响,以及儿童在自然条件下使用纸质媒介和数字媒介进行阅读时发展性阅读障碍发生率的差异,为发展性阅读障碍阅读干预研究提供参考。研究发现,阅读媒介会影响发展性阅读障碍的发生率,数字媒介环境下发展性阅读障碍的发生率明显高于纸质媒介环境。采用数字媒介阅读时,发展性阅读障碍儿童语音能力比纸质阅读时的表现逊色,汉字识别能力、同音语素能力、多义语素能力、阅读理解能力则不存在显著差异。同时,实验还发现存在一类儿童——数字媒介性阅读障碍儿童,他们在纸质阅读时并未表现出阅读困难,而在数字阅读时表现出持续性阅读困难,该类儿童的汉字识别能力、语素能力、语音能力和阅读理解能力均受到数字媒介的影响。图2。表6。参考文献36。     

Co-developmental trajectories of psychological need satisfactions at school: Relations to mental health and academic functioning in Chinese elementary school students

This study explored the co-developmental trajectories of autonomy, competence and relatedness need satisfactions at school and their relations to mental health and academic functioning in Chinese elementary school students. An accelerated longitudinal design was used with a sample of three cohorts (grade 3, grade 4, and grade 5) (N = 1070, 45.8% female; M_age = 9.44, SD = 0.97) on four occasions at 6-month intervals. Parallel process latent class growth models revealed five heterogeneous patterns (i.e., Congruent-moderate; Congruent-high; Congruent-low; Congruent-decreasing; Low-autonomy, High-competence and relatedness), all of which significantly associated with time-varying mental health and academic functioning indicators. The findings highlight the importance of subgroup differences and possible cultural considerations in understanding the progression of psychological need satisfactions and the need for universal screening and dynamic monitoring of students’ psychological need satisfactions at school and implementing more sophisticated interventions tailored to the unique characteristics of the relevant subgroups to promote optimal mental health and learning.     

Developmental discourses as a regime of truth in research with primary school students

While developmental discourses have been heavily critiqued in relation to education systems, less attention has been paid to how these impact the data collection process in classroom research. This article utilises Foucault’s concept of regime of truth to highlight the pervasiveness of developmental discourses when conducting research in primary schools. Such a theoretical framing makes explicit how developmental discourses work and are constructed as ‘truth’, which limit the possibilities for alternative perspectives. This article shows how this regime of truth works in practice by reflecting on qualitative research conducted with two age groups in two primary schools in Australia, focusing on the researcher’s navigations of these discourses. In particular, this article examines the impact of developmental discourses on conducting research with multiple age groups, initiating research, choosing methods for data collection, and negotiating power relations and ethical practices.     

发育性颈椎管狭窄与脊髓型颈椎病的相关性分析

目的：进一步探讨脊髓型颈椎病与发育性颈椎管狭窄的关系。方法：应用比值法对70例正常人和110例脊髓型颈椎病患者的X线侧位片进行统计学测量与比较，研究范围从C3～C7。结果：C3～C7正常组与颈椎病组的椎管中矢径比值有显著性差异。结论：发育性颈椎管狭窄是脊髓型颈椎病的重要发病因素。     

论发展性教学艺术形成

发展性教学艺术是主体性教育指导下的教学艺术,它最利于学生个性全面和谐的发展.为了形成发展性教学艺术,教师首先应确立发展性教学的基本思想,形成发展性学生观,学会让学生主体参与教学,形成指导学生理解文本与进行超文本理解的艺术.     

浅析发展性学校评价的动力缺失及对策建议

发展性学校评价理念在落实的过程中存在动力缺失的问题,究其原因,主要有：评价主体对发展性学校评价的认识存在偏差、评价反馈环节薄弱、组织缺失和合作文化缺乏以及内部评价与外部评价失衡等,为了有效激发评价动力,需要从以下几点着手：正确认识发展性学校评价、完善评价机制、注重校内合作文化建设、加强内外部评价之间真诚对话等。     

中国煤炭城市的发展绩效评价和转型影响因素分析

本文利用基于松弛的序列方向性距离函数,测算了2003-2010年中国30个煤炭城市工业经济的市场、环境效率和相应的全要素生产率指数,并采用二元选择模型分析了煤炭城市发展模式转型的影响因素。结果显示:在研究期间内,多数煤炭城市表现为生产率进步,且进步主要源于技术变动,而效率变动对生产率进步的贡献呈现起伏波动的不稳定状态;中国煤炭城市的发展主要分布于“市场高效环境高效型”和“市场低效环境低效型”两类模式之中;科技投入水平和城市开放程度提升显著地促进了煤炭城市转型,而资源依赖性上升是煤炭城市转型的显著阻力。     

Profiles and predictors of behavioral resilience among children in child welfare

Children living in out-of-home care have experienced a multitude of adversities, often resulting in compromised functioning. The current study used Ontario Looking After Children (OnLAC) project data to estimate developmental trajectories of behavioral outcomes (i.e., conduct and emotional problems) over a 4-year period (i.e., ages 6–10 to 9–13) in 313 children living in out-of-home care. Predictors measured at baseline (e.g., sex) and across the subsequent 4-year period (e.g., parenting practices) were also investigated. Findings indicated that 64.2% and 58.6% followed resilient trajectories for conduct behaviors and emotional functioning, respectively. Predictors of resilient trajectories included internal developmental assets, number of children in the home, whether the child was receiving treatment, and positive parenting. Findings need to be interpreted with an understanding that children in out-of-home care have varying levels of functioning across various domains (e.g., educational, social) other than the ones measured here. Predictors were static and dynamic and cut across various contexts, emphasizing the importance of considering child functioning within an ecological model.     

A MIRCENS’ Network to Safeguard Nature's Invisible Assets

The effect of age on the way that children aged 7–16 years classify food was examined in a cross‐section of Welsh school children. Primary school children were interviewed and invited to classify photographs of food into groups. Secondary school children undertook a similar task using cards on which were written the names of foods. Although by 7 years of age children had well‐established food classification strategies, there are considerable differences between those used by older and younger children. A time of particular change was seen in the use of classification labels during the first year of senior school with children aged 11–12. Potential implications of the findings for the design and implementation of nutrition education programmes are considered.
