The need for data literacy is an increasingly pressing priority in society, but most of the work in data-centred education has focused on developing skills at the middle school, secondary, and post-secondary levels, with little attention on the potential for engaging elementary-aged students in reasoning with and about data. This paper reports…

The lesson set in this article describes an introductory learning experience using wildlife camera-based citizen science projects hosted on Zooniverse (http://www.zooniverse.org). Wildlife camera projects were chosen due to the charisma of the study organisms, student engagement while looking at images, ease of access to projects, ease of teaching…

Nowadays, knowledge dissemination among children is no longer limited to the classroom and course or information books. It also includes websites explicitly addressed to youngsters who have a different stage of cognitive development and background knowledge compared to adults. However, they are also the first to live in today's multimodal…

Many researchers, teacher educators, teachers and students view graphics in text as an aspect of student learning (e.g. engagement, comprehension). However, as a field we have not addressed teachers' pedagogical content knowledge and decision-making associated with the use of graphics, student learning and issues of access. This mixed methods…

As a group of middle school mathematics teachers and teacher educators, the authors have focused their attention on using innovative practices coupled with high cognitive demand tasks to engage students, pique their interest in mathematics, and promote conceptual understanding. This article explores their three-act task design. In act 1, students…

The activities described here allow students to explore the concept of diffusion with the use of common equipment such as computers, webcams and analysis software. The procedure includes taking a series of digital pictures of a container of water with a webcam as a dye slowly diffuses. At known time points, measurements of the pixel densities…

The challenges of implementing learner-centred pedagogies have been well documented, noting that many reform efforts fail to consider important contextual factors. With attention to the disparity between policy and practice, this study investigated the conditions under which teachers can enact learner-centred pedagogy in the Maldives using…

The most common activity in a social studies classroom should be the analysis of primary sources. Students are intrigued and engaged by edited and unedited documents, written statements, transcribed speeches, photographs, pictures, charts, graphs, cartoons, and even material objects. Ideally, the goal of social studies teachers is to prepare…

Middle school teachers tend to rely heavily on texts that have become increasing more visual. There is little information available about the graphical demands of general middle grades' science texts. The purpose of this study was to quantify the type and quality of the graphical representations and how they interacted with the textual material in…

It has long been known that when a cable of specified length is hung between two poles, it takes the shape of a catenary--a hyperbolic cosine function. In this paper, we study a variation of this problem. First, we consider a cable hanging between two poles in which one end of the cable is fixed to one pole; the other end of the cable runs over a…

Collecting data and analyzing the results of experiments is difficult for children. The authors found a surprising way to help their third graders make graphs and draw conclusions from their data: digital photographs. The pictures bridged the gap between an abstract graph and the plants it represented. With the support of the photos, students…
