Proof plays many important roles in mathematics. Proofs should do more than simply verify that a statement is true; instead, a proof should also explain why a statement is true and enrich both the author's and the readers' understanding of the statement and important mathematical ideas within it. Common practice in high school geometry classrooms…

Despite holding wide-ranging experiences with constant velocity and non-zero acceleration, students wrestling with physical science concepts struggle to demarcate the two distinct characteristics of motion. In fact, this prior experience and loose familiarity with associated terminology often act as an obstacle toward a deep and robust…

We report on our experience with the implementation of project-based teamwork on nuclear energy with 14 ninth-grade students from a lower secondary model school and its assessment using two written questionnaires, which were answered by the students after the completion of the project. The first questionnaire elicited students' opinions about the…

This study examined the effects of task demand and familiarity on students' perception and processing of spatial information upon viewing visuospatial representations. Participants in South Korea were told that they would travel through an area, either drawing a map or observing the scenery depicted in photographs. The level of familiarity in the…

The purpose of this article is to familiarize teachers with the concept of executive functioning and to provide them with a collection of strategies that they can use to help support middle and high school students with planning, organization, task-initiation, and impulse control.

Spatial skills have been shown in various longitudinal studies to be related to multiple science, technology, engineering, and math (STEM) achievement and retention. The specific nature of this relation has been probed in only a few domains, and has rarely been investigated for calculus, a critical topic in preparing students for and in STEM…

As 21st century skills (e.g., creativity and collaboration) are informally developed by tech-savvy learners in the Digital Age, technology-based strategies to develop such skills in non-formal and formal contexts are necessary to reduce the gap between academic and business organizations on the one hand, and the revolutionary wave of self-taught…

Research has demonstrated that instruction that relies heavily on studying worked examples is more effective for less experienced learners compared to instruction emphasizing problem solving. However, the guidance associated with studying some worked examples may reduce the performance of more experienced learners. This study investigated…

Full membership is acceptance and belonging in a school community where all stakeholders have a voice and the culture is reflective of these values and beliefs. This qualitative study compared the perceptions of general and special education teachers from two southern high schools. The author explored how scripts of disability inform teacher…

Learning the symbolic language of chemistry is a difficult task that can be frustrating for students. This article introduces a game, ChemOkey, that can help students learn the names and symbols of common ions and their compounds in a fun environment. ChemOkey, a game similar to Rummikub, is played with a set of 106 plastic or wooden tiles. The…

This article documents how second language (L2) Spanish learners in an American high school formulated explicit grammar rules during three inductive lessons on the pronominal clitic "se." Following Adair-Hauck "et al." (2010), each lesson first presented a property of "se" within a narrative text, and then had learners inductively "Co-construct"…

In the last decade, the issue of teaching the Palestinian perspective on the Jewish-Arab conflict in Israeli schools gave rise to considerable debate and competing curricula. A quasi-experimental study compared the effects of these competing approaches on learners' attitudes to out-group narratives and perceived in-group responsibility (IR). A…

In a North Texas school district, students taking online courses in a variety of subject areas were not successfully completing courses at the district's expected levels. The district pays for courses and student support while remaining financially responsible to the community and programmatically to students' online success. Students'…

This paper explores the impact of a Teaching and Learning Audit of all government schools in Queensland, Australia. This audit has a concern with the extent to which schools "differentiate classroom learning". We note that in England, since September 2012, one of the standards that teachers have been expected to demonstrate is an ability…

English, particularly regarding a foreign language teachers' professional development, has been studied in depth. However, it is not known how Iranian English as a foreign language teachers perceive continuing professional development. This study explored the perceptions of Iranian English as a foreign language teachers of continuing professional…
