The Gale-Shapley stable marriage theorem is a fascinating piece of twentieth-century mathematics that has many practical applications--from labor markets to school admissions--yet is accessible to secondary school mathematics students. David Gale and Lloyd Shapley were both mathematicians and economists who published their work on the Stable…

An analysis of one-step equations from a cognitive load theory perspective uncovers variation within one-step equations. The complexity of one-step equations arises from the element interactivity across the operational and relational lines. The higher the number of operational and relational lines, the greater the complexity of the equations.…

The article discusses current issues related to the implementation of the UNESCO roadmap implementing Global action programme on education for sustainable development. In the context of increasing the professional level of pedagogical workers is a priority area in the implementation of education for sustainable development. Therefore, we believe…

Interactive experiences are rapidly becoming popular via the surge of "escape rooms"; part game and part theatre, the "escape" experience is exploding globally, having gone from zero offered at the outset of 2010 to at least 2800 different experiences available worldwide today. CrashEd is an interactive learning experience that…

This article suggests that logic puzzles, such as the well-known Tower of Hanoi puzzle, can be used to introduce computer science concepts to mathematics students of all ages. Mathematics teachers introduce their students to computer science concepts that are enacted spontaneously and subconsciously throughout the solution to the Tower of Hanoi…

There are two approaches for providing Tier 2 interventions within Response to Intervention (RtI): standard treatment protocol (STP) and the problem-solving approach (PSA). This article describes the multi-tiered RtI prevention model being implemented across the United States through an analysis of these two approaches in reading instruction. It…

Although much of the scientific community concerns itself with ideas of a sustainable future, very little of this interest and motivation has reached the classroom experience of the average chemistry major, and therefore, it is imperative to expose students to these ideas early in their careers. The focus of most undergraduate chemistry curricula…

MAUVE (magnitude, answer, units, variables, and equations) is a framework and rubric to help students and teachers through the process of clearly solving and assessing solutions to introductory physics problems. Success in introductory physics often derives from an understanding of units, a command over dimensional analysis, and good bookkeeping.…

Everyone has problems, from the smallest ant competing for a food source to the largest elephant needing to cool down. Fortunately, organisms have structures that function to help them solve these problems. So when a group of fourth-grade students look for solutions to their problems, who do they turn to? A biological champion, of course! Plants…

Learning celebrations are increasingly common in schools looking to put more emphasis on community and efficacy in place formulaic science fair projects. The celebration aspect is in the community's participation and interaction with the learners. Students are the main event, performing as they would in a school play or applying acquired knowledge…

The Smarties-Box Challenge encourages students to apply several different mathematical capabilities and concepts--such as, estimation, multiplication, and the notion of being systematic--to solve a complex, multistep problem. To effectively engage in the Smarties-Box Challenge, students are required to demonstrate aspects of all four proficiency…

One area of algebraic thinking essential for students' success is a relational understanding of the equal sign. Research has indicated a positive correlation between students' relational understanding of the equal sign and their equation-solving performance, suggesting that students' early conception of the equal sign may affect their learning and…

This essay presents and discusses an eight-session seminar course designed to develop critical thinking skills in doctoral biochemistry students by exposing them to classical experiments in biochemistry. During each 2.5 session, different key topics of the discovery and development of biochemical concepts are discussed. Before each session,…

Framing mathematics ability as innate or intimately connected to someone's intelligence is common. Have you ever heard a parent or colleague say something akin to, "Jonathan can really write, but I don't know what happened in math!"? Unfortunately, this framing not only narrowly describes how mathematics learning occurs but also raises…

Active learning classrooms provide an ideal opportunity to develop key workplace skills such as teamwork, information processing, critical thinking, and problem solving. Although many active learning pedagogies implicitly support student development of these skills, the role of the instructor in explicitly prompting and assessing these skills in…
