Schematising activities in early childhood education

The purpose of this study was to determine the importance of introducing schematising to children in early childhood and to determine whether schematising can be taught to children. This was done using a longitudinal, quantitative study with a quasi-experimental design (N = 133). In this study, the use of schematising was taught to an experimental group of children to determine if it is possible to realise significantly improved results in schematising tasks for an experimental group in comparison to a control group of children who were not taught schematising. Pupils in the experimental group demonstrated significantly better results on schematising, which cannot be explained by maturation. In our future research, we will investigate the mathematical performances of these experimental and control groups in the next grade of the primary school curriculum.     

Teacher educators working on their own professional development: goals,activities and outcomes of a project for the professional development of teacher educators

This article reports on the professional development of teacher educators within the context of a national project, ‘Professional Quality of Teacher Educators,’ where a professional standard and a standards‐based procedure of (self‐)assessment and professional development have been created and effectively implemented. This project offered a unique opportunity to analyze the goals, activities and outcomes of the process of professional development of teacher educators in a situation in which this development is promoted by the professional group as a whole. In our research, we used 25 completed portfolio's made by teacher educators participating in the standards‐based procedure of (self‐)assessment and professional development. We found that teacher educators, participating in this procedure, prefer the development of their knowledge and skills over the development of their attitudes and beliefs. For their professional development, the teacher educators experiment with new activities within the work‐situation and interact with colleagues within their professional community, more than that they study theory or reflect on their work. The participating teacher educators experience a positive impact at the personal level (change in cognition and behavior). More than one‐third of them share outcomes with others. Above, they report a more positive self‐esteem and more enthusiasm for teacher education. This article may motivate other countries or institutions to invest in the professional development of teacher educators. Further research is necessary on the essence of the professional qualities of teacher educators and the relation of their professional development with student learning.     

General Growth Mixture Analysis of Adolescents' Developmental Trajectories of Anxiety: The Impact of Untested Invariance Assumptions on Substantive Interpretations

Substantively, this study investigates potential heterogeneity in the developmental trajectories of anxiety in adolescence. Methodologically, this study demonstrates the usefulness of general growth mixture analysis (GGMA) in addressing these issues and illustrates the impact of untested invariance assumptions on substantive interpretations. This study relied on data from the Montreal Adolescent Depression Development Project (MADDP), a 4-year follow-up of more than 1,000 adolescents who completed the Beck Anxiety Inventory each year. GGMA models relying on different invariance assumptions were empirically compared. Each of these models converged on a 5-class solution, but yielded different substantive results. The model with class-varying variance–covariance matrices was retained as providing a better fit to the data. These results showed that although elevated levels of anxiety might fluctuate over time, they clearly do not represent a transient phenomenon. This model was then validated in relation to multiple predictors (mostly related to school violence) and outcomes (grade-point average, school dropout, depression, loneliness, and drug-related problems).

Introducing Children to Anatomy: “Getting to Know Our Bodies: The First Step Toward Becoming a Scientist”

Museums are used in every discipline to collect, classify, and present information for scientific purposes. They also serve as an effective educational medium. Since the establishment of a boutique anatomy museum at Bahçeşehir University, lectures, conferences, and seminars have been organized there over the past four years on the history of human anatomy and the human body. In order to raise awareness about the need to make anatomy accessible to kindergarteners and school-aged children, rather than exclusively to undergraduate students, activities that are suited to a wide range of ages have been developed at the museum and at the anatomy laboratory. Four different sessions were conducted, including activities such as lectures using plastic models as props, shaping organs out of playdough, anatomy puzzles, watching cartoons, and examining specimens through a microscope. Healthy and pathologic anatomies were chosen to match daily themes. Among the kindergarteners and elementary school children, no grading was done, nor was any questionnaire administered; however, a survey was administered in the 10–12 age group (N = 64). According to the students' written feedback, 93.75% said they “are happy with microscope activities” while 84.37% said they “had so much fun” participating in the playdough activities. However, 18.75% criticized the activities, saying they “could have been longer.” In conclusion, it is believed that these “getting to know our bodies” activities that were hosted in the anatomy museum, including conferences, workshops, material preparation, and instructional movies, may play an important role in the development of a healthy society.

Visuospatial working memory in adolescents with poor performance in mathematics: variation depending on reading skills

The first purpose of this study was to investigate whether the visuospatial working memory (VSWM) skills of 15–16‐year‐old pupils with difficulties in mathematics differ from those of their normally achieving peers. The goal was to broaden the view of the complex system of VSWM. A set of passive and active VSWM tasks was used. The study’s second purpose was to investigate whether pupils with mathematical difficulties differed in their VSWM skills based on whether they had signs of reading deficits or not. Results indicate that the pupils with poor performance in maths showed poorer performance on certain VSWM tasks. The group with deficits only in maths had less capacity for storing passive visual simultaneous information, while the group with difficulties both in maths and reading had deficits in both storing (passive visual and visuospatial information) and processing, and had less ability to control irrelevant visuospatial information compared to their peers of the same age. The results indicate a general VSWM deficit in pupils with both mathematics and reading problems and a specific VSWM deficit in pupils with only mathematics problems.     

略论"媒介批评"的概念及其起源

国内2001年出版的两本媒介批评专著关于媒介批评概念与起源的认识与理论总结存在着一些偏差。本文认为媒介批评是人们依据一定的新闻传播观念或理论,并且参照新闻史的背景来对新闻传播实践中存在的问题进行的批评活动。媒介批评的起源从认识论角度可以追溯到新闻媒介的起源,经历了从口头自发批评到文字批评再到自觉的系统理论批评的发展历程。
