An exploration of the common content knowledge of high school mathematics teachers

open access: yesPerspectives in Education, 2014
Many studies point to the problem of poor mathematics content knowledge of  mathematics teachers in South Africa. The purpose of this study was to investigate teachers’ knowledge of the mathematics they are themselves teaching.

In Situ Graph Reasoning and Knowledge Expansion Using Graph‐PRefLexOR

open access: yesAdvanced Intelligent Discovery, EarlyView.
Graph‐PRefLexOR is a novel framework that enhances language models with in situ graph reasoning, symbolic abstraction, and recursive refinement. By integrating graph‐based representations into generative tasks, the approach enables interpretable, multistep reasoning.

Graph Attention Neural Networks for Interpretable and Generalizable Prediction of Janus III–Vi Van Der Waals Heterostructures

open access: yesAdvanced Intelligent Discovery, EarlyView.
A crystal graph neural network based on the attention mechanism is proposed in this work. The model dynamically weights features through the attention mechanism, enabling precise prediction of properties of material from structural features. Here, taking Janus III–VI van der Waals heterostructures as a representative case, the properties have been ...

A Shared Control Method of Multiobjective Motion Fusion for Surgical Robot

open access: yesAdvanced Intelligent Systems, EarlyView.
This paper proposes an innovative shared control method that can handle multiple objectives task by integrating various types of controllers. It not only takes into account the priorities among the objectives but also allows for the flexible addition or removal of objective controllers.

BAXTER ALGEBRAS AND DIFFERENTIAL ALGEBRAS

open access: yesDifferential Algebra and Related Topics, 2002
A Baxter algebra is a commutative algebra $A$ that carries a generalized integral operator. In the first part of this paper we review past work of Baxter, Miller, Rota and Cartier in this area and explain more recent work on explicit constructions of free Baxter algebras that extended the constructions of Rota and Cartier.

Reprogrammable, In‐Materia Matrix‐Vector Multiplication with Floppy Modes

open access: yesAdvanced Intelligent Systems, EarlyView.
This article describes a metamaterial that mechanically computes matrix‐vector multiplications, one of the fundamental operations in artificial intelligence models. The matrix multiplication is encoded in floppy modes, near‐zero force deformations of soft matter systems.

Prerequisite Relations Annotation Tool: Annotation and analysis of educational relations in texts

open access: yesJournal of the Association for Information Science and Technology, EarlyView.
Abstract Relations between terms in texts have long been studied in linguistics and specialized knowledge domains, especially when occurring in educational materials like textbooks, where they play a crucial role in guiding instructional design and learning.
