This experiment describes a simple protocol for teaching acid-base titrations using potentiometry, conductivity, and/or photometry to determine end points without an added indicator. The chosen example examines the titratable acidity of a red wine with NaOH. Wines contain anthocyanins, the colors of which change with pH. Importantly, at the…

A bottleneck in gathering big data about learning is instrumentation designed to record data about processes students use to learn and information on which those processes operate. The software system nStudy fills this gap. nStudy is an extension to the Chrome web browser plus a server side database for logged trace data plus peripheral modules…

The primary objective of the activity presented here is to allow students to explore the frequency components of various simple signals, with the ultimate goal of teaching them how to remove unwanted noise from a voice signal. Analysis of the frequency components of a signal allows students to design filters that remove unwanted components of a…

The velocity selector is a classic first-year physics problem that demonstrates the influence of perpendicular electric and magnetic fields on a charged particle. Traditionally textbooks introduce this problem in the context of balanced forces, often asking for field strengths that would allow a charged particle, with a specific target velocity,…

One of the requirements for interior design students by the Council for Interior Design Accreditation is to be "prepared to work in a variety of contexts as well as across geographic, political, social, environmental, cultural, and economic conditions." To help with this preparation, faculty partners from two institutions--the University…

Understanding spatial reasoning is important to success in mathematics. This article shows how the proficiency strands in the "Australian Curriculum: Mathematics" provide the tools needed for effective teaching and learning of spatial thinking.

Research has discovered a link between physical activity and learning, where students who are more physically active and fit perform better in the classroom. Since most classroom settings are sedentary in nature, physical education is an ideal environment to connect physical activity and classroom content (i.e. math, English language arts,…

Drawing on data from preschools in Australia and the United States, the authors highlight strategies to help teachers demystify the process of engaging young learners with tangible technologies and showcase how robotic manipulatives serve as catalysts for peer collaboration, socio-emotional development, and creative problem solving.

The ties between literacy and numeracy exist in the development of vocabulary and language for understanding mathematical concepts. Research indicates that explicit instruction in mathematics vocabulary supports success with mathematics problem solving (Biemiller 2009; Pierce and Fontaine 2009; Rubenstein and Thompson 2002) for native…

Building sets, video games, and scatterplots may seem unrelated, but when they are combined into a problem-based learning (PBL) lesson, these elements join to create a unique learning experience. PBL lessons drive instruction by focusing learning and activities around a central challenge or question while providing a relevant, captivating, and…

Just as a compass orients a traveller, the OECD Learning Compass 2030 indicates the knowledge, skills, attitudes, and values students need not just to weather the changes in our environment and in our daily lives, but to help shape the future. The Learning Compass 2030 is composed of seven elements: (1) core foundations; (2) transformative…

Mastering the ability for learning to learn is the most ambitious goal of modern educators. A distinction is made between two relatively independent components of this expertise: (a) the reflective component of the learning to learn ability that allows a person comprehend what knowledge and skills he or she lacks to act in the new situation; (b)…

Project-Based Learning (PBL) is increasingly popular in K-12 schools, not just in the United States but around the world. PBL is a great way to engage students in their learning. In this article, the author presents what PBL is and is not.

Top-down implementation of technology is one of the most pervasive phenomena of the last couple of decades in educational history. It is the subject of many books, articles, and blog posts on how to fix schools or why educational technology is not working in the classroom. The idea of providing teachers with technology so they can make students…

Mathematical modeling is an important and accessible process for elementary school students because it allows them to use mathematics to engage with the world and consider if and when to use it to help them reason about a situation. It fosters productive struggle and twenty-first-century skills that will aid them throughout their lifetime.
