Sustaining the teaching profession: Innovating the ‘golden thread’ in university‐led teacher education

British Educational Research Journal, EarlyView.
Abstract This paper examines the implications of England's ‘golden thread’ policy framework for teacher education, which describes a state‐mandated, linear model of professional learning from initial teacher training and education through to continuing professional development.

Re‐thinking teachers' professional development: An analysis of National Professional Qualifications for school leaders in England

British Educational Research Journal, EarlyView.
Abstract This article considers how teachers' professional development could be redeveloped to help address the current crisis in teacher recruitment and retention by offering greater intellectual rigour and more opportunities for intellectual growth. Our analysis is focused on the UK government's current policy for leadership development in schools in

Growth mindset is positively associated with mathematics attainment in Scotland—But socioeconomic status plays a greater role

British Educational Research Journal, EarlyView.
Abstract There is currently a gap in knowledge around pupils' growth mindset (GM) and attainment in Scotland, particularly in relation to Socioeconomic Status (SES). This study offers insights on the relevance of growth mindset in Scotland for attainment in mathematics by drawing on large‐scale data from the OECD's Programme for International Student ...

Fouling‐Free Inertial Microfluidic Cell Clarification for Lentivirus Manufacturing

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Lentiviral vectors (LVVs) are widely used as gene‐delivery vehicles in cell and gene therapy, enabling stable integration of transgenes into target cells. However, efficient clarification of LVV harvest remains a major bottleneck in large‐scale manufacturing, as conventional depth filtration often results in significant product loss.
