The importance of reducing the gender gap in engineering programs by recruiting and retaining female students is well recognized. Although women hold roughly half of all jobs in the United States, only 24% of STEM jobs are occupied by women. The problem is even more pronounced for engineering, where women held about 12% of jobs as of 2013 (Corbett…

A series of pedagogical problem set exercises are posed that illustrate the principles behind material efficiency green metrics and their application in developing a deeper understanding of reaction and synthesis plan analysis and strategies to optimize them. Rigorous, yet simple, mathematical proofs are given for some of the fundamental concepts,…

In October 2014, an interesting new app became freely available in the Apple Store®. It is called PhotoMath®: (1) Hold a phone or tablet up to a mathematics problem in a textbook; (2) The app shows the answer to the problem; and (3) Select Steps to see the step-by-step process for getting from the problem to the solution. The app works for simple…

This paper outlines a programme "Safe and Social" that has been implemented with adults with intellectual disability across multiple contexts in a service based in Ireland. The emphasis within the programme is on providing service users and staff with a framework and the necessary language to discuss social behaviours and boundaries,…

This article discusses the status of World Geography Education and the importance of these concepts in developing 21st century students. Moreover, the authors also showcase how World Geography concepts can be intentionally taught through a technological/engineering, design-based learning challenge that requires students to solve a global housing…

Supporting students to develop an understanding of the meaning of fractions is an important goal of elementary school mathematics. This involves developing partitioning strategies, creating representations, naming fractional quantities, and using symbolic notation. This article describes how teachers can use a formative assessment problem to…

In the last decade, engineering education has evolved in many ways to meet society demands. Universities offer more flexible curricula and put a lot of effort on the acquisition of professional engineering skills by the students. In many universities, the courses in the first years of different engineering degrees share program and objectives,…

Quick leadership transitions may succeed in other industries, but they don't usually work in the "business of relationships" we call school. Boards that respond to a solvable problem by firing the head may believe that action is necessary and good for the school. In truth, these abrupt changes almost always hurt schools, with devastating…

According to recently published national standards, elementary students should engage in engineering design activities. This article outlines ways that teachers can use literacy instruction to support young students' engineering design activity, such as by selecting texts in which characters face problems that can be solved through engineering,…

The method of least-squares (LS) has a built-in procedure for estimating the standard errors (SEs) of the adjustable parameters in the fit model: They are the square roots of the diagonal elements of the covariance matrix. This means that one can use least-squares to obtain numerical values of propagated errors by defining the target quantities as…

The implementation of troubleshooting within a pre-existing expository laboratory is described and evaluated. Student feedback indicated that troubleshooting activities are highly effective in providing a hands-on opportunity to exercise problem-solving skills and gain a better understanding of the whole process in addition to effectively…

Creative and critical thinking skills are the abilities, which can sometimes be used interchangeably in definition. In fact, they have different constructs because they differentiate in outcome of human behaviours. Also one of today's requirements is that individuals should approach everyday problems by using both competences. So, one of the…

Austin Independent School District (AISD) teacher appraisal results from 2014-2015 were used to identify areas of need for professional development in 2015-2016. Results from the Professional Development and Appraisal System and Professional Pathways for Teachers (PPfT) were included. This executive summary provides highlights from the full report…

This article describes an instructional model for integrating children's literature and language arts into the elementary school science curriculum. This science-literacy instructional model is an adaptation from the original 5E model of scientific inquiry. The model demonstrates how reading, writing, listening, and speaking can be incorporated…

Increasing availability of digital devices in elementary school classrooms presents exciting new opportunities for teachers to support the teaching and learning of mathematics. Although many of the math applications available for these devices focus on drill and practice of mathematical procedures, screencasting apps can help support effective…
