Julie Lynem’s son had taken algebra in eighth grade, but hadn’t comprehended some of the core concepts. After a family discussion, we decided he would repeat Algebra 1 in ninth grade,” Lynem, a journalism lecturer, wrote in CalMatters. Perhaps most controversial was its treatment of algebra.
In the face of mounting evidence, education experts accepted a prescriptive fact: student success is not measured by milestones like ‘took a foreign language in fifth grade’ or ‘passed Algebra in high school’ but by how s/he thinks. Thinking Flexibly. Thinking Flexibly. Managing impulsivity. Persisting.
In its current form, school algebra serves as a gatekeeper to higher-level mathematics. Researchers and policy makers have pushed to open that gate—providing more students access to algebra, focusing in particular on those students historically denied access to higher-level mathematics. Let’s Not Be So Quick to Give Up on Algebra.
Introducing Tabular Manipulating Data in Tabular Getting Data into Tabular Cleaning Data for Tabular The Structure of Tabular Tabular Everywhere Algebra with Symbolic Arrays Language Tune-Ups Brightening Our Colors; Spiffing Up for 2025 LLM Streamlining & Streaming Streamlining Parallel Computation: Launch All the Machines!
One can view a symbolic expression such as f[g[x][y, h[z]], w] as a hierarchical or tree structure , in which at every level some particular “head” (like f ) is “applied to” one or more arguments. So how about logic, or, more specifically Boolean algebra ? We’ve looked at axioms for group theory and for Boolean algebra.
When confronted with real-world math problems with multiple answers, students will be able to think more creatively and flexibly. The curriculum for algebra classes, for example, will move at a faster and more efficient pace. How Can Academic Enrichment Boost Student Success? Enriched Knowledge.
The function Map takes a function f and “maps it” over a list: Comap does the “mathematically co-” version of this, taking a list of functions and “comapping” them onto a single argument: Why is this useful? As an example, one might want to apply three different statistical functions to a single list. is PositionSmallest. In Version 3.0
be the primary measure of success in a course, and some measure of grace and flexibility will be included along with high standards and "rigor" And for other instructors, this concept raises more questions than answers. For some instructors, it provides hope that student growth will (finally!) A misplaced trust in statistics.
Events are like functions, whose “arguments” are incoming tokens, and whose output is one or more outgoing tokens. The systems can be based on Boolean algebra, database updating or other kinds of ultimately computational rules. At the level of individual events, ideas from the theory and practice of computation are useful.

In 2000 I was interested in what the simplest possible axiom system for logic (Boolean algebra) might be. of what’s now Wolfram Language —we were trying to develop algorithms to compute hundreds of mathematical special functions over very broad ranges of arguments. Yes, there can be a lot of flexibility in this model.
has a very flexible way of representing its results, that allows for different numbers of variables, different numbers of solutions, etc. ✕. we’re connecting to “Descartes-style” analytic geometry, converting geometric descriptions to algebraic formulas. Here’s a first example of a new convenience function: SolveValues.
