A nanotechnology module was developed for ninth grade students in the context of teaching chemistry. Two basic concepts in nanotechnology were chosen: (1) size and scale and (2) surface-area-to-volume ratio (SA/V). A wide spectrum of instructional methods (e.g., game-based learning, learning with multimedia, learning with models, project based…

A summer academy is held for grade 9-12 high school students at the University of Toronto, Toronto, ON, Canada, every year. The academy, dubbed the Da Vinci Engineering Enrichment Program (DEEP), is a diverse program that aims to attract domestic and international high school students to engineering and sciences (and possibly recruit them). DEEP…

The use of handheld computers in educational contexts has increased considerably in recent years and their value as a teaching tool has been confirmed by many positive experiences, particular within collaborative learning systems (Mobile Computer Supported Collaborative Learning [MCSCL]). The cost of the devices has hindered widespread use in…

This study describes the analogical models and narratives used to introduce and teach Grade 9 chemical covalent compounds which are relatively abstract and difficult for students. We explained each model's development during the lessons and analyzed understanding students derived from these learning materials. In this context, achievement,…

After-school programs specifically designed to improve students' mathematics achievement in collaboration with classroom teachers' planning and in class daily instruction have been found to be successful in improving student learning (Hock, Pulvers, Deshler, & Schumaker, 2001). The purpose of this article is to describe the results of an…

The Algebra Project DR K-12, funded by the National Science Foundation as a Research and Development Project, addressed the challenge of offering significant STEM content for students to ensure public literacy and workforce readiness. The project's primary purpose was to test the feasibility and effectiveness of a model for establishing four-year…

English language learners (ELLs) often find themselves marginalized with respect to learning mathematics in U.S. schools due, in part, to language barriers and gaps in prerequisite math knowledge and skills. The goal of this study was to use Sen's (1980, 1992, 1999) capabilities approach model as a lens through which to analyze the relationship…
