Students’ Procedural Fluency in Fraction Addition through Built-in Definition Fraction Media

SJME (Supremum Journal of Mathematics Education)
This study aims to describe elementary students’ procedural fluency in solving fraction addition problems using the built-in definition fraction media. Fraction operations are often challenging for students, particularly when determining common denominators and applying calculation procedures accurately.

Symbolic Regression and Multi‐Objective Optimization of the Flory–Huggins Interaction Parameter for Hydrogels

Advanced Engineering Materials, EarlyView.
We develop a data‐driven method to derive the mathematical expressions of the Flory–Huggins interaction parameter χ for the swelling behavior of temperature–responsive hydrogels. Starting from initial assumptions of χ, our workflow combines Bayesian optimization, Flory–Rehner theory, and symbolic regression to generate candidate χ expressions.

Investigating the use of models to develop Grade 8 learners’ conceptual understanding of and procedural fluency with fractions

, 2017
Both my teaching experience and literature of this research study strongly suggested that fractions are difficult to teach and learn across the globe generally, and Namibia in particular.

Microstructure Evolution of a VMnFeCoNi High‐Entropy Alloy After Synthesis, Swaging, and Annealing

Advanced Engineering Materials, EarlyView.
The synthesis and processing (rotary swaging and annealing) of the novel VMnFeCoNi alloy is investigated, alongside the estimation of the grain size effect on hardness. Analysis of a wide grain size range of recrystallized microstructures (12–210 µm) reveals a low annealing twin density.

Investigating the Students’ Mathematical Fluency and Procedural Skills using P-cube (P³) as an Authentic Assessment

International Journal of Research in Social Science and Humanities
Mathematical fluency and procedural skills are essential for students to deepen their understanding of mathematics and apply knowledge to real-world situations. However, the 2022 PISA results revealed that the Philippines continues to perform poorly in mathematics, underscoring the need to strengthen these competencies among students.

A Lightweight Procedural Layer for Hybrid Experimental–Computational Workflows in Materials Science

Advanced Engineering Materials, EarlyView.
We unveil a prototype hybrid‐workflow framework that fuses automatedcomputation with hands‐on experiments. Built atop pyiron, a lightweight, parameterized layer translates procedure descriptions into executable manual steps, syncing instrument settings, human interventions, and data capture in real‐time today.

Influence of Test Temperature and Test Frequency on Fatigue Life of Aluminum Alloy EN AW‐2618A

Advanced Engineering Materials, EarlyView.
The influence of test temperature and test frequency on the fatigue life of EN AW‐2618A is investigated. High‐cycle fatigue tests are performed at different test temperatures and frequencies on the 1000 h/230°C overaged state. Both test parameters reduce fatigue life due to time‐dependent damage mechanisms.
