The authors describe a mathematics lesson designed to allow students to use their own thinking to solve elapsed time problems. Their approach emphasises student-centered structured inquiry, and follows a 'Launch, Explore and Summarise' format.

The International Mathematical Modeling Challenge takes place towards the end of Term 1 each year in Australia. Students use their research, mathematical and creative abilities to develop a mathematical model to address a real world problem. Ross Turner describes some aspects of the competition.

Classroom methods that facilitate student learning from iteration have received little attention from scholars. Iterative learning requires students to repeat a problem-solving task in new contexts each time applying lessons from previous applications. Iterative learning formats improve students' learning outcomes and help instructors ensure that…

Although science, technology, engineering, and mathematics (STEM) initiatives have received increased attention in recent years (Bybee 2011), the focus is often on science and mathematics (Thornburg 2009). Yet, engineering has been referred to as "the glue that holds the other STEM subjects together" (Thornburg 2009). With the release of…

Chemistry education research (CER) as a field is inherently interdisciplinary and has traditionally borrowed ideas, frameworks, and methodologies from other fields, such as anthropology, psychology, cognitive science, and science education more broadly. In this paper we encourage researchers to continue this tradition by utilizing the rich body of…

Integrating the disciplines of mathematics and science is one way to place the calculations of volume and surface area into a real life context. The authors present an activity for middle-school students that aims to promote their learning of these key concepts in a personally meaningful way, whilst also developing inquiry and problem solving…

Rosemarie T. Truglio is the senior vice president of curriculum and content at Sesame Workshop, where she is responsible for the development of the interdisciplinary curriculum on which "Sesame Street" is based, and oversees content development across platforms such as television, publishing, toys, home video, and theme park activities.…

These notes discuss several related propositions in geometry that can be explored in a dynamic geometry environment. The propositions involve an unexpected property of quadrilaterals.

Word problems are an essential component of providing a context for computation but are also recognized as an enduring struggle for students. Students are challenged to solve these story-based problems, often resorting to trial and error. This article presents meaningful alternative approaches to helping students make sense of word problems.

The sandwich problem described in this article would likely be considered more appropriate for third grade or above. However, as members of the research team for a lesson study involving teachers from kindergarten through fourth grade, the authors saw kindergarten students rise to the challenge. The authors invite readers to review two scenarios,…

At the start of every school year, teachers typically wonder what their new students know coming into the grade level. Sometimes, though, they place too much emphasis on what children do not know or have forgotten over summer break. After all, those gaps can be glaring. Helping their students grow is like helping an acorn grow; they must watch for…

This is a study of my dramatized narrative based on a true story of what took place in a mathematics class in an international school setting. My narrative includes the exploration of a mathematical "mistake" and the discovery of newly emergent problems. The drama, commentary, and reflections provide a close examination of the conduct…

Visually impaired or blind students require adjustments to the traditional hands-on activities and methodological and didactic strategies employed by the teacher. These adaptations are based on multisensory teaching tools, which reinforce the learning of all students in general. This paper presents simple teaching resources that allow students…

Algebra is considered an important high school course because it is recognized as the gateway to higher mathematics, college opportunities, and well-paying jobs. In the United States, most secondary schools require students to be proficient in algebra to be able to graduate from high school. One major component of algebra is word problem solving,…

The Group Exercises is a distinctive collaborative group working activity completed by approximately 170 second-year undergraduate chemistry students each year in June. The activity comprises students working in randomly allocated teams of 4-6 members to complete a structured learning package to solve chemistry problems with industrial relevance…
