Person-centred reviews and transition: an exploration of the views of students and their parents/carers

The person-centred review (PCR) is a model for the review of a student’s special educational needs (SEN) which places the young person and their family at the centre of the process. This mixed-methods, exploratory study investigated the views of 16 students with SEN aged between 10–11 years (Year 6) and 13–14 years (Year 9), and their parents/carers on their PCRs (which were mostly held at transition). Attention was paid to potential changes in the young people’s locus of control and feelings towards school. Findings indicated that the PCR is a collaborative, constructive and reassuring process for families where a wealth of information is shared openly and honestly within a relaxed, yet structured, meeting. The young people were generally positive about the process, although many felt daunted beforehand. Some parents felt the meeting was too long and not entirely accessible to children. The study did not conclude that the young people’s locus of control or feelings towards their education changed following the PCR. Implications for good practice are discussed, particularly for educational psychologists and in the context of the SEN and Disability Code of Practice.     

Adolescents’ Social Networks: Exploring Different Patterns of Socio-Digital Participation

The purpose of the study was to assess adolescents’ participation in various socio-digital activities by using a self-report questionnaire, a social networking questionnaire, and interviews. The participants (n?=?253) were grade 6–9 students from a multicultural lower-secondary school in Finland. Three profiles of socio-digital participation were identified: friendship oriented basic participators (n?=?161), gaming-oriented participators (n?=?61), and creative participators (n?=?31) intensively engaged in diverse socio-digital practices. The analyses revealed systematic differences in social networking relations as a function of adolescents’ social-digital participation profile and gender. The reciprocal values in hanging out, liking, and media multiplexity were highest for creative participators, whereas gaming-oriented participators were less socially active than their peers. The socio-digital expertise of creative participators was socially recognized by a larger group of peers than that of the other groups. The study produces methodological tools suitable for collecting systematic longitudinal data of socio-digital practices of larger groups of adolescents in future.

试论辩证唯物主义总体性原理在当代的发展

本文着重论述了恩格斯的总体性物质自组织原理（简称哲学总体性原理）在改造德国古典哲学中的形成和发展问题。该原理在当代又有了重大的发展。从本体论看,核宇宙已揭示了以核聚变为动力的“宇宙熵”的双向演化的总体机制;从认识论看,哲学熵在信息核能时代是对“宇宙熵”的能动的哲学反思,弄清哲学熵与宇宙熵的同一性和差别以及哲学熵的社会特有的能动性就能更好掌握哲学总体性原理的新内容和时代方法论价值取向。哲学熵与总体性原理相结合必将促进唯物主义和辩证法的总体结构与方法的信息化的新发展。

论学生的主体地位在教学活动中的建构

中小学教学活动，关键在于充分体现教学的主体性精神。承认学生在教学中处于主体地位，即承认学生在教学中既是认识活动的主体，又是价值活动的主体。活动是学生主体地位得到落实的重要保证。学生的活动及活动方式必须得到巧妙的安排和组织。
