Images of Science Linked to Labwork: A Survey of Secondary School and University Students

This paper presents findings about the images of science drawn upon in laboratory work, by upper secondary and university students, in academic streams with a science focus. Data were collected through four written questions, administered to a total of 368 students. The questions all required students to comment on laboratory investigations carried out by research scientists or by science students. We show that students' reasoning has an epistemological and an ontological dimension, and that it often differs significantly from accepted perspectives on the nature of science. The issue for teaching appears to be showing students what counts (and what does not count) as appropriate reasoning in actual situations. In other words, explicit teaching about the various relationships that can exist between theory and data would transform labwork towards a more critical process that involves making and justifying decisions.     

Challenges in identifying target skills for math disability screening and intervention

Gersten, Jordan, and Flojo (in this series) review their research on math difficulties, with an emphasis on applying current knowledge to inform practices of early identification and intervention. On a practical level, educators are in dire need of empirically based screening and intervention tools. From a scientific perspective, it is important to recognize the need to clearly define what we seek to identify and remediate, and to acknowledge that we are currently far from achieving this goal despite recent advances in the field. Among the studies reviewed by Gersten et al., as well as other studies by several other researchers, there is much variability in how mathematics difficulties are defined and measured, and even in the terms used to refer to them. I address the degree of consensus and controversy currently characterizing the state of math learning disabilities research, with an emphasis on the usefulness of a developmental perspective in appraising this young field.     

Adult outcomes in women who experienced parental violence during childhood

OBJECTIVE: The aims of this work are to analyze the associations between violence suffered at the hands of fathers and mothers in childhood and adolescence and three outcomes in adulthood--having or not having children, marital status, and occupational status--controlling for the possible impact of partner violence. METHOD: This cross-sectional study examined a sample of 510 women, attending various health care and social services facilities in a Northern Italian city. Both quantitative and qualitative data were collected. RESULTS: Almost one quarter of the respondents reported some kind of abuse by one or both parents, and 18.2% had experienced physical and/or sexual violence by a partner or ex-partner; women abused by parents were more likely to experience partner violence. Irrespective of whether they experienced partner violence, women abused by parents were more likely to be childless, divorced or never married, and in a precarious occupational situation. CONCLUSIONS: This study is the first one carried out in Italy on this subject: results largely confirmed the trends found in studies in other countries. However, two of the associations which emerged, namely between parents' abuse and being divorced or never married and between parents' abuse and being childless, are worth noting, since they could be interpreted as failures or, on the contrary, as active and positive choices made by abused women in a difficult context. Qualitative data from case histories provided insights into the violence some women have suffered and its consequences, but also into women's great resilience and strengths.     

Collaborative learning at the computer; How social processes ‘interface’ with human-computer interaction

In drawing an ‘outline sketch’ of the field of research on interactional learning situations with computers, this paper attempts to provide a general framework for the contributions which follow. After a brief overview of the theoretical grounding of studies in the field, we examine the extent to which learner-computer interaction and learner-learner interaction can interfere with or support one another.

The need for a change of theoretical perspective on the role of social interaction in learning is highlighted. It is argued that viewing collaborative learning in terms of joint negotiation of a common problem space might help in defining the optimal characteristics of educational software.

Finally, the critical role of social dimensions such as social comparisons between partners is pointed out. In conclusion, the need for more local theories, taking particular account of the learning domain, is stressed.

     

Building strong parent–teacher relationships in primary education: the challenge of two-way communication

This study investigates which subjects teachers talk about with parents in parent–teacher conferences and other contact moments, and how they communicate with regard to these subjects. Fifty-five in-depth interviews were carried out with teachers from special education schools, at-risk schools serving low socio-economic status children and mainstream primary education schools in the southern part of the Netherlands. The results illustrate that (1) two-way communication is used the most in at-risk schools, (2) teachers find it difficult to involve parents in the decision-making process concerning special care for the child, and (3) the teachers’ attitude towards parents is best when it comes to difficult discussion topics. When situations are really difficult, teachers stand alongside the parents instead of addressing them from their expert role, asking them ‘How can we solve this together?’. Teachers should be more aware of this quality, and not be afraid to address difficult subjects or conflicts.     

Students’ relationships to knowledges,place identity and agency concerning the St. Lawrence river

Our study is framed according to a transformational-sociocritical approach to an education for sustainable development (ESD) that, in particular, considers landscapes as learning contexts of potential use for fostering engagement in the areas of environmental protection and sustainable development. In keeping with this perspective, we surveyed students aged 16–17 years from the Lower St. Lawrence region (Quebec, Canada) concerning their knowledge and perceptions of issues pertaining to the St. Lawrence, the river facing them on an everyday basis, and about their role as citizens in that connection. In respect of theoretical considerations, we propose developing the concepts of relationships to knowledge, place identity and agency. An analysis of questionnaires (N=334) has served to: bring out the learnings and issues pertaining to the St. Lawrence River that students consider to be meaningful; characterise the various identity-centred relationships with this landscape; and define the eco-civic agency of the students surveyed. The results of this analysis then provide a basis for some proposals for an ESD curriculum relating to the St. Lawrence River that is rooted in students’ concerns. While the environmental issues dealt with occur locally, the potential transfer of results into other curricula and educational contexts is also discussed.

Gender difference does not mean genetic difference: Externalizing improves performance in mental rotation

The fear of underperforming owing to stereotype threat affects women's performance in tasks such as mathematics, chess, and spatial reasoning. The present research considered mental rotation and explored effects on performance and on regulatory focus of instructions pointing to different explanations for gender differences. Two hundred and one participants were asked to perform the Mental Rotation Test (MRT) and were told that men perform better than women. Then they were divided into four sub-groups and provided with no additional information (control condition) or one of three explanations: (a) genetic factors, (b) widely-held stereotype, or (c) time limit. A decrease in performance was predicted for the genetic instruction and an increase for the two alternative explanations based on externalizing. Results showed that both women and men are harmed by the genetic explanation and relieved by both the stereotype and the time limit explanations. Explanations stressing genetics and time limit as factors affecting performance favor prevention focus.     

Numerical Magnitude Representations and Individual Differences in Children's Arithmetic Strategy Use

Against the background of neuroimaging studies on how the brain processes numbers, there is now converging evidence that numerical magnitude representations are crucial for successful mathematics achievement. One major drawback of this research is that it mainly investigated mathematics performance as measured through general standardized achievement tests. We extended this research by investigating the association between numerical magnitude representations and children's strategy use during single‐digit arithmetic. Our findings reveal that children's symbolic but not nonsymbolic numerical magnitude processing skills are associated with individual differences in arithmetic. Children with better access to magnitude representations from symbolic digits retrieve more facts from their memory and are faster in executing fact retrieval as well as procedural strategies. These associations remain even when intellectual ability, digit naming, and general mathematics achievement are additionally controlled for. All this indicates that particularly the access to numerical meaning from Arabic symbols is key for children's arithmetic strategy development, which suggests that educators and remedial teachers should focus on connecting Arabic symbols to the quantities they represent.     

Autonomic Regulation on the Stroop Predicts Reading Achievement in School Age Children

In this study we examined high frequency heart rate variability (HF‐HRV, a parasympathetic index) both at rest and during challenge, to assess if variations in cardiovascular activity measured during a Stroop task could be used to predict reading achievement in typically developing children. Reading achievement was examined using the Peabody Individual Achievement Test–Revised. Results showed that greater HF‐HRV suppression during both the Stroop word and Stroop word–color conflict tasks was associated with better reading achievement. Higher basal levels of HF‐HRV did not predict better reading scores. These results are among the first to show a link between HF‐HRV and reading achievement in a normative school age population, and offer new insight into the association between cognitive activity and autonomic regulation of the heart.
