For students to be successful in algebra, they must have a truly conceptual understanding of key algebraic features as well as the procedural skills to complete a problem. One strategy to correct students' misconceptions combines the use of worked example problems in the classroom with student self-explanation. "Self-explanation" is the…

This article describes a method of instruction using an active learning strategy for teaching stoichiometry through a process of gradual knowledge building. Students identify their misconceptions and progress through a sequence of questions based on the same chemical equation. An infrared device and software registered as the TurningPoint Audience…

Learners are all different and teachers are all different, so why do we often ignore this reality when trying to explain, or demystify, some aspect of mathematics in the classroom? Enabling learning can be challenging, demanding of creativity, and needy of alternatives if understanding is the real goal. Here the authors offer ideas that are aimed…

In this article, the authors explore framing, a non-multiplicative technique commonly employed by students as they construct similar shapes. When students frame, they add (or subtract) a "border" of fixed width about a geometric object. Although the approach does not yield similar shapes in general, the mathematical underpinnings of…

The "Balance of Nature" metaphor is a pervasive idea in ecology. However, the scientific community acknowledged during the last decades that equilibrium conditions are rare, while disturbance events are not uncommon. We suggest that the exclusive teaching of the "Balance of Nature" metaphor produces cultural, scientific and learning misconceptions…

Today's students are inundated with information--via social-networking websites, personal blogs, collaborative wikis, online-only publications, and so on--that ranges from biased personal opinions to peer-reviewed scientific papers. Some sources describe science events accurately; others don't. Students should understand how this media coverage…

Effectively teaching the concepts of osmosis to college-level students is a major obstacle in biological education. Therefore, a novel computer model is presented that allows students to observe the random nature of particle motion simultaneously with the seemingly directed net flow of water across a semipermeable membrane during osmotic…

This paper argues that research on the educational uses of technology frequently overemphasizes the influence of technology. Research in the field is considered a form of critical perspective, and assumptions about technology are questioned. Technological determinism is introduced, and different positions on this concept are identified. These are…

A simple, conceptual method is described for using the spreadsheet scroll bar to find the composition of a system at chemical equilibrium. Simulation of any kind of chemical equilibrium can be carried out using this method, and the effects of different disturbances can be predicted. This simulation, which can be used in general chemistry…

The concept of "function" spans elementary school through high school. When introducing the topic to elementary school and middle school students, the authors ask them to work with a variety of examples and representations of functions, since a formal definition of a function is rather abstract. They give the most accessible geometric functions…

In this paper, we describe animations and animated visualizations for introductory and intermediate-level quantum mechanics instruction developed at the University of St Andrews. The animations aim to help students build mental representations of quantum mechanics concepts. They focus on known areas of student difficulty and misconceptions by…

The purpose of this workshop paper is to understand the ways that women and men who work in the field of composition-rhetoric studies can more fully understand and articulate ways to enable women writing students to use more fully the new kinds of technology that proliferate in the digital realm. The material is based on the author's twenty-six…

It's been a rough time for the image of K-12 virtual education. Studies in Colorado and Minnesota have suggested that full-time online students are struggling to match the achievement levels of their peers in brick-and-mortar schools. Articles in "The New York Times" questioned not only the academic results for students in virtual schools, but…

This article discusses the role of open and distance learning to widen participation and promote social inclusion within Australian higher education, as well as the benefits that open educational resources (OER) could bring to that context. It also explores some of the most relevant social inclusion policies and related initiatives developed in…

The periodic table and the periodic system are central to chemistry and thus to many introductory chemistry courses. A number of existing activities use various data sets to model the development process for the periodic table. This paper describes an image arrangement computer program developed to mimic a paper-based card sorting periodic table…
