Studying children’s social learning experimentally “in the wild”

Diffusion studies are taking us a step closer to understanding social learning and cultural transmission in young children. The first half of this article presents a review that focuses on four main cultural issues addressed by diffusion studies: (1) horizontal transmission, including child-to-child learning; (2) learning in children’s everyday environments (“in the wild”); (3) the experience of multiple demonstrations and attempts at mastering new tasks; and (4) the iterative process of learning across multiple cultural “generations.” The second half of the article introduces an open-diffusion experiment. After an initial asocial-learning phase in which children had the chance to discover two possible solutions to a puzzle box, the box was brought into the children’s playgroup, thus allowing observational learning. Although variation of method use occurred in the asocial-learning phase, by the end of the second day of the open diffusion, the group had converged on a single method. The open-diffusion approach allowed the documentation of social interactions not seen in the dyadic studies typical of the field, including both coaction and scrounging, the significance of which for cultural transmission is discussed.     

'They don't give us our marks': The role of formative feedback in student progress

This paper presents the results of an experimental evaluation of a change in assessment practice in one comprehensive secondary school. The school divided 104 Year 7 pupils into four mixed-ability teaching groups. One of these was given enhanced formative feedback on their work for one year, but no marks or grades. The other three groups were given marks and grades with minimal comments, which was the usual prior practice in this school (and many others). Using data derived from assessment, prior attainment, pupil attitudes and background information, we conducted a contextualized analysis of progress in the four teaching groups for all subjects. This showed that progress in the treatment group (formative feedback only) was substantially inferior to that of the other three groups. In this paper, we also use data from observation of the process and from group interviews with the students involved, to help explain these results. Our findings are relevant to a consideration of the often lessened impact of research findings when 'rolled' out into wider practice, and what may be done about this.     

Publisher–Society partnerships to further image accessibility and global inclusivity in the Humanities and Social Sciences: Comparing top-down and bottom-up approaches

• Collaboration between publishers and learned society partners can accelerate and amplify DEIA outcomes.
• 97 HSS titles have adopted alt-text publication workflows and this change has been welcomed by journal authors and editors.
• Efforts to promote global inclusivity do not always result in greater membership diversity, retention and growth.
• Top-down, publisher-led DEIA initiatives are effective when they are aligned strategically to pre-existing society initiatives.
• Bottom-up, member-led DEIA initiatives benefit from publisher support to mitigate financial and time-based barriers to active participation.
• To reliably track DEIA outcomes, publishers ought to adopt systematic data collection strategies through initiatives like C4 and the Joint Commitment.

     

Children with dyslexia are slow writers because they pause more often and not because they are slow at handwriting execution

It is commonly assumed that children with dyslexia are slower at handwriting than other children. However, evidence of slow handwriting in children with dyslexia is very mixed. Thirty-one children with dyslexia, aged 9 years, were compared to both age-matched children and younger spelling-ability matched children. Participants completed an alphabet-writing task and a composition task on the surface of a digital writing tablet. Children with dyslexia wrote the same amount of letters per minute in the alphabet task but wrote fewer words per minute when composing their texts than children of the same age. Crucially, no differences were found between children with dyslexia and their same age peers for speed of handwriting execution, measured by the tablet, when writing the alphabet or composing their texts. However, children with dyslexia were found to pause within their compositions as often as the spelling ability matched group. Thus handwriting execution is not impaired in children with dyslexia. The slow writing that is typical of children with dyslexia is due to pausing more often when composing and is related to spelling ability. This may reflect processing problems in response to high cognitive load through having to contend with spelling and composing concurrently.
