Many researchers have studied who and what teachers notice from video and some have focused on the analytic stance of teachers, meaning how noticing occurs. We complement existing work with a focus on analytic stance in a particular mathematics domain, proportional reasoning. We engaged 30 practicing teachers in an online course that included…

This article presents a guide to implementing oral history projects in Spanish language courses, drawing from our fifteen-year collaborative initiatives with various community organizations in the Trenton area. Among these is our comprehensive Puerto Rican Oral History Project, which resulted in five short video documentaries and over sixty…

Background: Data visualizations transform data into visual representations such as graphs, diagrams, charts and so forth, and enable inquiries and decision-making in many professional fields, as well as in public and economic areas. How students' data visualization literacy (DVL), including constructing, comprehending, and utilizing adequate data…

Technology development has been integrated into the educational environment and has led teachers to become much better trained in educational, technological tools. Currently, education is being transformed; for this, there are new methodological approaches, and education needs the integration of digital tools. Previously and still today,…

Video analysis is carried out for one-dimensional motion and collision experiments using Tracker. Physical variables, i.e. displacement, time, and velocity, can be deducted from the analysis and allows one to connect them to the equation of motion and energy conservation. Corresponding equations of motions are given without neglecting the effect…

Conjectures are a key component of mathematical inquiry, a process in which the students raise conjectures, refute or dismiss some of them, and formulate additional ones. Taking a design-based research approach, we formulated a design principle for personal feedback in supporting the iterative process of conjecturing. We empirically explored the…

Background: Digital media are pervasive in the lives of young people and provide opportunities for them to learn about STEM. Multiple theories argue that the STEM media environment may shape how youth see a STEM career in their future. Yet, little is known about how pre-college digital media consumption may be related to students' STEM career…

Recognized as one of the most beautiful experiments of all time, the oil drop experiment performed by Robert Millikan and his graduate students (primarily Harvey Fletcher) is a standard in the repertoire of experiments performed by undergraduate physics students. However, "as a teaching lab it does not enjoy a good reputation for three…

Framing through the concept of precarity, we share our arts-based research on the experiences of creating a collaborative performance-making project focused on connecting students from different education levels, to create a film-dance integrated performance to advocate for social justice issues in education. We, as instructors and researchers,…

The chemistry of metal-organic frameworks (MOFs), a new class of emerging crystalline porous solids with three-dimensional (3D) networks composed of metals and multidentate organic molecules, was introduced by using three differently shaped crystals. We reported new and mild MOF synthesis methods that are simple and devised to be performed in high…

This article combines Bourdieusian practice with narrative sociomaterial theory to investigate what story of higher education and its purpose is being conveyed to students. Our case study revolves around a Danish university. We conduct a sociomaterial analysis of three university sites: an information day for prospective students, a video of a…

In this paper we present a qualitative analysis based on data collected by means of an eye-tracker tool, concerning the outcome of a mathematical analysis question administered to a group of candidates of university level or higher. One of the research aims is to highlight similarities and differences in the visual observation of the question…

The objective of this study is to design a temperature measurement system based on a non-contact method using a sensor camera from a webcam. The material being measured is nickel wire given an electrical current of 4.5 A-6.5 A with an interval of 0.5 A. The temperature measurement is based upon the measurement of the average pixel value…

In South Africa, limited studies have been conducted investigating responsive teaching and little is known about how teachers respond to unexpected events 'in the moment' that did not form part of their planning. In this article, we report how a Grade 9 novice and expert teacher responded to unexpected learner offers during the teaching of algebra…

High school students have been through profound changes and challenges in the last three years. The experiences of the pandemic, lockdowns, virtual classes, and economic and social disruptions have had tremendous--and possibly lasting--impacts on them. As they prepare to enroll in college, have those experiences changed how they search for…
