The research reported in this article sought to develop a taxonomy of grade 11 students' levels of understanding in algebraic problem-solving tasks. The student sample was from high schools in the province of Ontario in Canada. Problems from four areas in algebra namely, variables, expressions, equations and word problems were chosen to be…

How can we use math to understand--and solve--challenges in our world? In "What We Do When Fairness Fails Us," Moises, Marissa, and Astrud realize that a specialized high school uses a lottery for admission that prevents many qualified students from attending. As they research how lotteries work, they come across videos by Federico…

Deliberation and inquiry can go hand-in-hand. Inquiry-based learning calls on teachers to facilitate student-led discovery, something that can only happen when students ask questions and weigh possible answers before settling on a plausible and evidentiary answer. Teaching through inquiry is about setting students up to wrestle with the issue at…

This report of the development of an intervention in practice outlines the design, delivery, and evaluation of a tailored, school-based, group adolescent sleep intervention utilising youth participation methodology and an intervention mapping protocol as a framework. The intervention also included supplementary video support. The intervention was…

In this article, the history of the golden ratio is discussed to demonstrate how exploring this ratio would be of value in a secondary mathematics classroom. Following this, a mathematical activity related to the golden ratio that is suitable for students from Year 7 to Year 12 is outlined.

Teacher-researcher, Katherine Macro spent six weeks observing an eleventh-grade Advanced Placement and Composition class at Sunnybrooke Central High School to examine the teacher's use of creative drama to teach Shakespeare. In this article, Macro describes ways the instructor used theater-based instructional strategies, especially a staged…

Quadratic equations are a notorious topic for the challenge it provides to students in secondary mathematics. Despite this, there is limited research, particularly in the Australian context, that explains why such challenges persist. This article details the causes of Year 11 students' difficulties in solving quadratic equations. Observing…

Below the surface of the ocean, currents, eddies, and other physical processes redistribute energy and biologically important elements. Measuring this transport can be challenging, and scientists must address a wide spectrum of oceanographic and engineering concepts when designing instruments to observe these processes. In this activity,…

This article describes how I, an American music teacher educator, visited the classrooms of eight Musical Futures Champion Teachers in the United Kingdom and observed their teaching with a focus on informal music learning and nonformal teaching. Musical Futures, a professional development organization in the UK, is the original organization that…

Currently, research surrounding transition programs for students entering high school focuses on academic achievement outcomes. However, the prevalence of school shootings in predominantly white, suburban communities shows that students in these often academically competitive schools may need support to help them become more connected to the…

The PreACT® suite of assessments (PreACT® 8/9, PreACT®, and PreACT® Secure™) can be used to monitor students' progress toward college and career readiness. Scores are classified into one of three readiness levels based on chances of meeting the ACT College Readiness Benchmark. This data byte presents the updated score ranges for each readiness…

Helping students reach a clear understanding of the cause-and-effect relationship between changes in parameter and the graph of an equation is the focus of the activity outlined in this article. The behavior of phase shifts has been regarded as counterintuitive for many people, and often, because of this, conflict between student intuition and…

Thanks to the development and deployment of federally funded satellite-, buoy-, and aircraft-based remote sensing instruments, continuous streams of Earth and space data are publicly available via online databases. This accessibility provides flexibility to explore geoscience data that are interesting and relevant to students--keystone components…

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,…

Boaler (2016) asserted that problem posing is the "essence of real mathematics", yet many students do not have opportunities to pose and then solve their own mathematical questions. Rather, students spend their time solving tasks someone else posed--often their teacher or textbook. To promote problem posing, the author designed,…
