The phenomenon of emerging water jets from the holes of containers has been extensively studied; nevertheless, it continues to inspire researchers and teachers. The main aspects of the recent studies concern: the range of the jets trajectories; the extension of Bernoulli's equation, of which Torricelli's expression represents an ideal situation,…

Over the past several decades it has become increasingly important to understand nature of science (NOS) for scientific literacy in science education. Science education researchers have suggested using socio-scientific issues to create a context for that purpose. The present fast-moving coronavirus or COVID-19 pandemic as a socio-scientific issue…

This paper describes an investigation looking at the underlying mathematics of poker machines. The aim of the investigation is for students to get an appreciation of how poker machines are designed to ensure that in the long-term players will inevitably lose when playing. The first part of this paper describes how students can model a simple poker…

A lesson that focuses on the intricate co-evolution of flowers with their pollinators is one way to help students learn the delicate balance in nature and help ensure that our actions do not upset this balance. In this lesson students use the engineering design process to engineer a flower that is a perfect model for its chosen pollinator. Next,…

In this article, the authors share what they learned from their study of writing communities, which they refer to as writing groups, during the 2017-18 school year. The authors propose a conceptual framework for writing groups that engages students in the process of designing and participating as writers with their peers. The framework emphasizes…

"Transcendentalism" refers to philosophical, religious, and literary beliefs held by Ralph Waldo Emerson, Henry David Thoreau, Margaret Fuller, Amos Bronson Alcott, and other writers in New England during the 1830s and 1840s. Emerson believed in the significance of one's intuition and individuality. He expresses these beliefs in his…

Graphing functions is an important topic in algebra and precalculus high school courses. The functions that are usually discussed include polynomials, rational, exponential, and trigonometric functions along with their inverses. These functions can be used to teach different aspects of function theory: domain, range, monotonicity, inverse…

Generalizing is a foundational mathematical practice for the algebra classroom. It entails an act of abstraction and forms the core of algebraic thinking. Kinach (2014) describes two kinds of generalization--by analogy and by extension. This article illustrates how exploration of fractals provides ample opportunity for generalizations of both…

A mysterious conflict of solutions emerged when a group of tenth- and eleventh-grade students were studying a seemingly ordinary problem on combination and probability. By investigating the mysterious "conflicts" caused by multiple randomization procedures, students will gain a deeper understanding of what it means to perform a task…

The plight of refugees has recently received considerable media coverage. Yet, little attention is given to groups who are internally displaced. The purpose of this article is to model one way to teach about internally displaced peoples, drawing on the Rohingya crisis as a specific example. We first provide a background of the Rohingya crisis, and…

Geospatial Inquiry is an educational framework that offers students an opportunity to engage with, and become curious about, geospatial data for a defined purpose. The authors define Geospatial Inquiry as: "Asking and answering a question through the analysis and communication of data that is linked to a geographic location on, above, or near…

"Louisiana Believes," the state's comprehensive plan to prepare students for college and career success, includes a system of related policies and programs that help schools provide students with pathways to future prosperity, give schools the resources to offer these pathways, and reward schools when students achieve their goals. This…

The implementation of the Common Core's Standards for Mathematical Practice can pose a challenge to all teachers of mathematics but especially to preservice teachers. These standards require teaching in a way that often differs from what preservice teachers have experienced as learners. Standard 1--"Make sense of problems and persevere in…

People are regularly confronted with environmental and science-related issues presented to them in newspapers, on television, or even in their own doctor's office. Often the information they use to inform their decisions on matters of science may be ambiguous and contradictory. This article presents an activity that investigates how students deal…

The traditional Run the Football Field physics activity--in which students are timed as they move at different speeds on a football field to investigate displacement and velocity--has been updated for the 21st century. Nowadays, GPS-enabled tablets and smartphones replace the stopwatches and yard markers of the past, allowing students to collect…
