Epistemic Objects and Tools on the School Grounds: Addressing Plant Blindness and Knowledge Construction

open access: yesScience Education, EarlyView.
ABSTRACT Plants mediate the supply of energy and matter for all animals, including human beings yet we are faced with “plant blindness” whereby we pay limited attention to and accord little value to plants. Plant blindness is evident in school curricula whereby students have limited opportunities to learn about plants.

Numerically efficient mechanical modeling of reinforced concrete membrane elements with fixed, interlocked cracks

open access: yesStructural Concrete, EarlyView.
Abstract Compression field approaches such as the Cracked Membrane Model with fixed, interlocked cracks (CMM‐F) are efficient tools for the mechanical modeling of reinforced concrete elements, providing the mechanical model σ=fε$$ \boldsymbol{\upsigma} =f\left(\boldsymbol{\upvarepsilon} \right) $$ required for finite element analyses.

Quantifying Structural Complexity, Effort, and Performance: An Early Experiment Using Network Design Tasks

open access: yesSystems Engineering, EarlyView.
ABSTRACT Structural Complexity is perceived as driving cost in system development, yet managing it effectively requires empirical understanding. This study investigates human decision‐making using a toy transportation‐style network design task, focusing on how Structural Complexity, Effort, and Performance interact. Seventy‐four participants (primarily
