The design of algorithms is one of the hardest topics of high school computer science. This is mainly due to the universality of algorithms as solution methods that guarantee the calculation of a correct solution for all potentially infinitely many instances of an algorithmic problem. The goal of this paper is to present a comprehensible and…

While reports of teachers' use of curriculum materials are common, that of teachers as designers of their own materials are far less so. We argue that these (rare) instructional materials, defined as materials that are classroom-ready and that carry the teachers' actual instructional goals, are 'objects' that are suitable as records of teachers'…

Mathematical concepts have been a consensus goal for decades, yet there is little consensus on what is meant by the terms "mathematical concept" and "mathematical understanding." This article attempts to discuss these terms in a way that can be of practical use to teachers. Greater clarity on "mathematical concept"…

This paper introduces CoCo, a system designed to support and encourage collaborative learning among colocated students sharing a single mobile device. It provides teachers with the possibility to create digital lessons, configure parameters for collaborative activities such as the number of students and tablets, and monitor students' progress. On…

For students to develop adequate conceptual understanding about fractions, they require experiences that afford them opportunities to think flexibly about multiple interpretations of fractions. This article presents a sequence of lessons designed to offer such experiences for students in Years 3 and Year 4. The lessons adopt a challenging tasks…

In schools, a lesson functions as an individual building block to support the learning of new material. Experts have identified key elements in an effective lesson, and education leaders--including school based administrators, instructional coaches, department and grade-level chairs--usually look for these elements when reviewing lesson plans and…

Digital curricula can constrain teachers with ready-made instructional materials. The authors used Mathematics Teaching Practices (MTPs) to modify a digital curriculum to engage students in more thoughtful and meaningful lessons. In this article, the authors visit one of their third-grade classrooms, in which they used the prescriptive digital…

In this paper, we discuss what creativity may look like in the science classroom and what we learnt from teaching with student-generated diagrams to promote creativity in Year 7 Science lessons. As a result of this study, most students were able to communicate a deeper understanding of complex phenomena and were able to apply this knowledge both…

Middle and high school students are part of Generation Z (birth years 1997-2012), a group that is emerging as very different from their parents and teachers. This article considers ways that generational research about Generation Z learners and NCTM's Effective Mathematics Teaching Practices can be used to inform and innovate practice in the…

Despite the best of intentions on the part of overworked and undertrained classroom teachers, instructional planning can too often be described as idiosyncratic, haphazard, and lacking any logically or pedagogically defensible structure. In this article, Tim Westerberg highlights the importance of a unifying planning framework that ensures…

Students not only vary in their skill level and preferences for academic content, but also in their social-emotional skills, development, and learning. This diversity in the classroom can pose instructional challenges, but it can be also an asset. It presents the opportunity for students to learn from and with one another, gain an understanding of…

Physical education classrooms reflect a range of learners, movers, and abilities. Incoming physical educators report lacking confidence and knowledge in their ability to create inclusive lesson plans. Many undergraduate and liberal studies students are required to take one adaptative physical education pedagogy course; thus, incoming educators…

With over 70% of fourth-, eighth-, and twelfth-grade students in the United States scoring below proficiency levels in writing (NCES, 2009), teachers must provide early and effective writing intervention to accelerate students' writing skills to meet grade-level standards. In this paper, we provide teachers with a theoretical framework to…

In response to increasing teacher interest in how to design and implement effective challenging tasks, James presents the Launch/Explore/Discuss model that builds on the work of leading Australian educators and researchers Peter Sullivan, Doug Clarke, and Charles Lovitt.

Student Uncertainty as Pedagogical Resource (SUPeR) is a teaching approach that science teachers can use to promote student scientific literacy, practice, and learning. SUPeR helps students navigate scientific uncertainty to improve understanding of scientific concepts and phenomena. The SUPeR approach consists of four phases: (1) problematize a…
