Energy is a critical concept in physics problem-solving, but is often a major source of confusion for students if the presentation is not carefully crafted by the instructor or the textbook. Confusion can be caused by the careless use of language in energy discussions. Students consciously or unconsciously imitate a teacher in their use of…

Teamwork and problem-solving skills have frequently been identified by business leaders as being key competencies; thus, teaching methods such as problem-based learning and team-based learning have been developed. However, the focus of these methods has been on teaching one skill or the other. A key argument for teaching the skills concurrently is…

A simple mathematical model for the behaviour of how vehicles follow each other along a looped stretch of road is described. The resulting coupled first order differential equations are solved using appropriate matrix techniques and the physical significance of the model is discussed. A number possible classroom exercises are suggested to help…

This article explores the use of classroom video as a tool for fostering productive discussions about teaching and learning. The setting for our research is a 2-year mathematics professional development program, based on the Problem-Solving Cycle model. This model relies on video from the teachers' own classrooms and emphasizes creating a…

Decades of research into learning have demonstrated that learners are diverse, changing, and adaptable. In this regard, the practice as educators must become flexible and adaptive to meet the wide variation of learning needs. A general consensus exists among educators, businesses, and other stakeholders that there is a significant gap between the…

There has been criticism about STEM education not focusing enough on problem solving, especially in authentic real-world contexts which are most often associated to ill-structured domains. To improve education, it is essential that curricula bring students to high levels of cognitive development by exposing them to authentic problems.…

"Blended learning" is using online tools to communicate, collaborate, and publish, to extend the school day or year and to develop the 21st-century skills students need. With blended learning, teachers can use online tools and resources as part of their daily classroom instruction. Using many of the online tools and resources students already are…

Many educators share the vision of the Equity Principle--teachers holding high expectations for all students. However, according to National Assessment of Educational Progress (NAEP) reports, minority students continue to lag behind white students in mathematics achievement. Furthermore, the discrepancies are more pronounced on the extended,…

This paper reviews and critiques the existing research on a widely recommended instructional approach called context-based physics, which involves placing physics material within a real-life context in an attempt to improve student motivation, problem solving, and achievement. Described first are the problems that exist with traditional physics…

The Council of Chief State School Officers (CCSSO), through its Interstate Teacher Assessment and Support Consortium (InTASC), offers this set of combined resources that define and support ongoing teacher effectiveness to ensure students reach college and career ready standards. This document includes the "InTASC Model Core Teaching…

This qualitative case study addresses the need for pedagogical approaches to working with open educational resources (OER). Drawing on a mix of historical thinking heuristics and case analysis approaches, a blended pedagogical strategy and primary source database were designed to build student understanding of historical records with transfer of…

In recent years, interest has increased in preschool programs that promote low-income children's early learning and development. Although research in this area has focused mostly on 4-year-olds, a growing number of 3-year-olds attend publicly funded preschool. In fact, in Head Start--a federally funded early childhood education program--the…

This report presents exploratory impact findings for 3-year-olds from the Head Start CARES demonstration, a large-scale randomized controlled trial implemented in Head Start centers for one academic year across the country. The study was designed primarily to test the effects of the enhancements on 4-year-olds, but it also provides an opportunity…

Preschool has long been viewed as a way to promote low-income children's early learning and development. Some promising classroom-based strategies have been found to enhance preschool children's social, emotional, and behavioral competencies. Most of this research has focused on 4-year-olds, even as a growing number of 3-year-olds attend Head…

Two problems in projectiles are discussed which generate interesting loci.
