Representing and recording student thinking in public spaces during mathematics discussions is challenging work. In this article, the authors articulate why skillfully recording and representing during discussions matters. The authors share principles for recording student thinking in the moment and share an activity structure to use with…

Pinhole camera photography is explored using a set of entomology pins due to their known pin diameters and availability in a variety of sizes. A procedure to prepare removable-lens digital cameras for pinhole photography is described. A video is included showing a set of ten insect pins and how to fit the camera with pinhole apertures. Formulas…

Cyberbullying is the use of digital communication tools and spaces to inflict physical, mental, or emotional distress. This serious form of aggression is frequently targeted at, but not limited to, vulnerable populations.

Massive online Open Courses (MOOCs) make extensive use of videos. Students interact with them by pausing, seeking forward or backward, replaying segments, etc. We can reasonably assume that students have different patterns of video interactions, but it remains hard to compare student video interactions. Some methods were developed, such as Markov…

Companies and individuals spent large sums of money to advertise in a variety of media, including newspapers, magazines, radio, TV, and, more recently, the Internet. Preying on the fears and insecurities of consumers, these entities used…

To efficiently create books and other instructional content from videos and further improve accessibility of our course content we needed to solve the scene detection (SD) problem for engineering educational content. We present the pedagogical applications of extracting video images for the purposes of digital book generation and other shareable…

In this article the possibilities to use video diaries as data collection tool in studies about scientific literacy are discussed. The starting point is a need for students to develop scientific knowledge which they can use as citizens in different situations. I argue that with this definition the students' scientific literacy (SL) must be…

In this paper, we present the integration of a Wiki with lecture recordings using a tool called "aofconvert", enabling the students to visually reference lecture recordings in the Wiki at a precise moment in time of the lecture. This tight integration between a Wiki and lecture materials allows the students to elaborate on the topics…

The most effective way to understand what a child knows about the reading process is to take a running record. In "Running Records", Mary Shea demonstrates how teachers can use this powerful tool to design lessons that decrease reading difficulties, build on strengths, and stimulate motivation, ensuring that children develop self-sustaining…
