Discriminant validity and interrelations of conceptual and procedural knowledge in fractions and algebra: Evidence from confirmatory factor analysis

British Journal of Educational Psychology, Volume 96, Issue 3, Page 1396-1418, September 2026.
Abstract Background Conceptual and procedural knowledge are two distinct types of mathematical knowledge. Measuring them with sufficient discriminant validity is challenging because they are typically highly correlated. Prior studies have demonstrated discriminant validity of paper‐and‐pencil measures separately for fractions and algebra.

Coal Mining as a Driver of Land Use and Land Cover Change and Degradation: A Case in Moatize City, Mozambique

Land Degradation &Development, Volume 37, Issue 13, Page 9126-9143, 15 August 2026.
ABSTRACT Coal remains a major global energy source despite ongoing environmental controversies, particularly, regarding climate change and landscape transformation. This study investigates the spatiotemporal dynamics of land use and land cover (LULC) in the Moatize Coal Basin (MCB), Mozambique, between 1990 and 2024, with a specific focus on land ...

Mechanistic Insights Into Surfactant‐Regulated and Carboxylate‐Mediated Uniform Zinc Plating

ChemSusChem, Volume 19, Issue 15, 14 August 2026.
Dendrite‐free zinc metal anodes are achieved by kinetic control of aqueous Zn plating using millimolar sodium dodecylbenzenesulfonate (SDBS) and ethylenediaminetetraacetic acid (EDTA) in a mildly acidic electrolyte. Persistent coadsorption slows interfacial charge–transfer, maintains Zn2+ surface concentration, and shifts growth from diffusion to ...
