Numerical estimation in adults with and without developmental dyscalculia

It has been hypothesized that developmental dyscalculia (DD) is either due to a defect of the approximate number system (ANS) or to an impaired access between that system and symbolic numbers. Several studies have tested these two hypotheses in children with DD but none has dealt with adults who had experienced DD as children.This study aimed to compare these two hypotheses in an adult population in order to investigate which deficits still persist at that age. To that aim, numerical estimation tasks were given to adults who had or had not experienced DD as a child. Three of the estimation tasks required a mapping between the ANS and symbolic numbers: participants had to estimate the number of same or different-sized dots presented by producing the corresponding Arabic number or, conversely, to produce the number of dots corresponding to a presented Arabic number. A fourth task did not require any processing of symbolic numbers; participants had to produce a collection of dots of the same numerosity as another one previously presented.Consistently, in all the four numerical tasks and irrespective of whether the tasks used symbolic numbers or not, the estimates of DD participants were less accurate than those of the control participants. These results indicate that adults who had experienced DD as children continue to demonstrate a less precise magnitude representation.     

Conceptions of inclusion and inclusive education: a critical examination of the perspectives and practices of teachers in Poland

This small‐scale study details the development and execution of a system of inclusive education in 20th and 21st century in Poland. A detailed review of the literature and employment of in‐depth semi‐structured interviews aimed to establish how inclusion is defined and operationalised in Poland. In addition, the study sought to establish how the teachers' levels of professional development and personal attitudes towards inclusion were influencing the evolution of this important educational initiative. The data from the study detail that the concept of inclusion is not well known in Poland, and that integrative education still dominates educational thinking. The study provides data to suggest integration in Poland works well in the early stages of education, but that it struggles to provide for and integrate older children into the mainstream educational settings. The research concludes that Poland has taken an important but perhaps faltering step towards educating all children in the mainstream schools.     

Dynamic task selection: Effects of feedback and learner control on efficiency and motivation

Structural features of learning tasks are relevant for problem solving but not salient for novice learners. Feedback in the form of Knowledge of Correct Response (KCR) during practice is expected to help learners recognize the structural features and to profit from learner control over the selection of learning tasks. A 2 × 2 factorial experiment (N = 118) was conducted to study the effects of the KCR feedback (present and absent) and control over the selection of learning tasks (learner control and program control). The presence of the KCR feedback yielded higher efficiency on a near-transfer test as well as higher learner motivation. An interaction between feedback and control, indicating extra beneficial effects of feedback when learners control the selection of learning tasks, was not found. Theoretical and practical implications are discussed.     

The relationship between teaching practices and student achievement in first year classes

This study investigated the links between the teaching practices of primary school teachers (n = 200) who were observed while presenting a new text to their first year classes, and the student achievement levels in those classes. The teaching practices are specifically concerned with the way the teachers supported and encouraged students’ activities during verbal interactions. Two different populations were observed: classes of first year students with a reduced teacher–student ratio (about ten students per class) and classes with a normal teacher–student ratio (between 20 and 25 students per class). We found that the average level of student achievement in the reduced size classes was higher than in the standard size classes but that teaching practices differed only at precise periods of group or individual introduction to new reading texts. In these periods, we found links between teaching practices and student achievement.     

Ian Serraillier The Silver Sword

Cle invited several classroom teachers to select a novel which regularly goes well with their classes, to analyse its success, and to discuss the ways in which they and their classes have shared the book together.Gill Bullen chose Ian Serraillier'sThe Silver Sword (published in the United States asEscape from Warsaw), which she enjoys teaching to eleven and twelve-year-old children of all abilities. John Hodgson, who has taught in both England and the United States, has found Albert Camus'The Outsider (published in the States asThe Stranger) to be a popular choice with students of fifteen and over.Further contributions from teachers will be published in our next issue.     

Research note

Conclusions The results of the present study seem to justify the following conclusions: (1) it is possible to identify several, relatively independent, and psychologically meaningful dimensions of the self-concept; and (2) the self-concept as measured by the Self-concept Scale functions independently of intelligence and academic aptitude as a correlate of academic achievement. Therefore, the new instriument has opotential to make an important contribution to the prediction of academic achievement. Since the istrument is only in its experimental stage, replication and cross-validation studies should be carried out to confirm the findings of the study.OISEBased mainly on Gill (1968).     

Women in Art: The Last Taboo

The intention of this paper is to explore traditions and current trends in art with particular reference to the depiction of female experiences such as pregnancy, abortion, birth and motherhood. The inclusion and exclusion of such images in art history over time and across societies reflects prevailing attitudes, whilst affirming various stereotypical and gendered constructions developed and sustained within those societies. These constructions in turn relate to criteria defined by class, access to education and notions of femininity. Work by artists which feature aspects of these experiences (particularly childbirth), is considered taboo by many in a Western society which continues to render the essentially female experience as private, invisible and stigmitised and confuses the natural with the sexual. The work of undergraduate art students, inspired by the artwork of women artists who make explicit or are influenced by essentially female experiences, is discussed and attempts made to connect their work to the issues outlined.
