A survey of 21 free online buffer calculators and apps found only 2 that correctly calculated pH under conditions where [H[superscript +]] and [OH[superscript -]] cannot be ignored in the ratio term of the Henderson-Hasselbalch equation. Traditional guidelines for when use of formal concentrations is acceptable were found to be flawed. For acidic…

This exploratory study investigated the behaviors and content of onscreen calculator usage by a nationally representative sample of eighth-grade students who responded to items from the 2017 National Assessment of Educational Progress mathematics assessment. Meaningful features were generated from the process data to infer whether students…

In this study, the effect of using on-screen calculators on eighth grade students' performance on two TIMSS 2019 Problem Solving and Inquiry Tasks items considered as examples of technology-enhanced items administered on computers was examined. For this purpose, three logistic regression models were run where the dependent variables were giving a…

In spite of the proliferation of educational technologies, teacher surveys have indicated relatively low levels of technology integration in mathematics lesson delivery in Ghanaian Senior High Schools. This study examined how Senior High School mathematics teachers use the available technology resources in their pedagogy in Ghana. Drawing on the…

The duo of artefacts is a simplified model of the complex systems of various manipulatives (either tangible or virtual) that mathematics teachers and their students use in classrooms. It offers a means to study the complexity of the interweaving of the tangible and of the digital worlds in the teaching and learning processes. A duo of artefacts is…

Technological resources in secondary education have had problems in their implementation, especially in public institutions, this has caused teachers to keep traditional learning methodologies, with minimal alternatives to use active methodologies due to the limited access to Information and Communication Technologies (ICT). The present research…

As I approach my 70th year in physics, let me tell my younger colleagues about my adventures with computation. When I was 14, my father gave me a slide rule because I appeared to be headed toward a career in physics. Since then, I have had experience with many other calculating devices.

While traditional graphing calculators have become commonplace in high school mathematics classrooms, newer and more powerful connected graphing packages (CGP) are less pervasive. This study observes how four teachers integrate a CGP into their high school mathematics classrooms, with a focus on the challenges the teachers faced and the…

This paper highlights the new enhancements of the Halomda platform designed to improve students' learning and exam preparation. The new features include a Graph Plotter, Algebraic Calculator and Context ChatGPT Recommended Key Guidelines. The use of these features is demonstrated though a working example of solving a double integral, illustrating…

The National Council of Teachers of Mathematics (NCTM), has made an effort to increase the use of technology and the use of calculators into the classroom and curriculum. As a result, many studies and articles have been written on the subject of calculator use in the classroom. A review of over 600 studies revealed that it is not curricula that…

Prospective teachers and cryptography students use programming, statistics and guile to enrich both their courses.

This study uses "Critical Race Theory," "Settler Colonialism," and "Critical Whiteness Studies" to frame how property is recognized only under the auspices of whiteness. In the college algebra classroom, this is born out through white entitlement, racialized senses of sharing, and resource allocation. This study uses…

Surveys are commonly used to determine how people feel about a specific issue. The increasing availability of the internet and popularity of social networking sites have opened up new possibilities for conducting surveys and, with limited additional costs, enlarge the pool of volunteer respondents with the desired background, experience, or…

Calculators are a viable option for educational technology in developing countries due to its affordability and accessibility; it is also supported by literature to have positive effects on the students' acquisition of mathematics concepts and skills positively. However, the stakeholders of education in Indonesia often stigmatize the use of…

This study reports on the development, validation, and reliability of a geometry disposition scale (GDS) to measure pre-service teachers' (PSTs') attitudes to geometry learning. PSTs from two Colleges of Education (CoEs) in Ghana volunteered to participate in the study (N = 153). A principal component analysis (PCA) extracted four factors: deep…
