Graph neural networks (GNN) are vital for analyzing real-world problems (e.g., network analysis, drug interaction, electronic design automation, e-commerce) that use graph models. However, efficient GNN acceleration faces with multiple challenges related to high and variable sparsity of input feature vectors, power-law degree distribution in the…

Middle school students need to know about energy concepts and how they can reduce their energy use. New energy-monitoring tools provide powerful opportunities for students to engage in authentic investigations rich in the science practices described in "A Framework for K-12 Science Education" (NRC 2012), while at the same time advancing their…

As anyone who has taught or taken a statistics course knows, statistical calculations can be tedious and error-prone, with the details of a calculation sometimes distracting students from understanding the larger concepts. Traditional statistics courses typically use scientific calculators, which can relieve some of the tedium and errors but…

This paper examines the technological affordances of the visualiser, and what teachers actually do with it in the primary (elementary) classroom, followed by an investigation into one example of teaching and learning with this whole-class technology. A visualiser is a digital display device. Connected to a data projector, whatever is in view of…

The graph of this function is analyzed by using calculus methods and the computer. The graph in most texts is shown to be misleading. (MP)

A computer program is presented that generates problem sets involving sketching graphs of trigonometric functions using graphical addition. The students use calculators to sketch the graphs and a computer solution is used to check it. (MP)

The generation by computers of random numbers is discussed. A BASIC program is given that will generate a set of normally-distributed random numbers. (MP)

Discussed are programs for the TRS-80 to draw vertical and horizontal bar graphs. A short set of exercises is included. (MP)

Methods for getting a computer-linked plotter to do a total plot of a relation are discussed. (DT)

Difficulties encountered when drawing the graphs of linear equations are discussed. Programs are developed to overcome these and worksheets are given for further practice. (MP)

Explains format, style rules, and lexicographic conventions that improve clarity and precision in a technical glossary. Discusses general rules, rules of style, rules of grammar and syntax, and rules for figures. Describes the computer display techniques and file management system used to develop such a glossary. (SR)

A method of approximating areas under curves in precalculus courses is described. (SD)
