In this case study, we investigate how an inquiry-oriented interactive calculus textbook supported one U.S. college instructor's classroom teaching. We utilized analytical inquiry-oriented frameworks on observation data from a small classroom to capture textbooks' influence on the instruction conceptualized by the Teacher-Mathematics-Student face…

Teachers' self-efficacy in managing classrooms is an important consideration when it comes to bringing educational robots to classrooms. Orchestration tools support teachers by providing awareness indicators of students' progress as well as levers to control the flow of the lesson. We designed and evaluated the impact of an orchestration tool for…

The objective of the present study was to gain a deeper understanding of how middle-grade mathematics teachers implement questions in both technology-supported and non-technology-supported classrooms. The investigation demonstrated that in-service mathematics teachers teaching in a technology-supported classroom and in a non-technology-supported…

There has been a limited amount of research that has attempted to determine teaching strategies using adaptive learning systems. Most studies have attempted to measure success of the use of these technologies based on improvements in students' test scores but have lacked to provide any information regarding the pedagogy implemented while using the…

The poor performance of students in mathematics indicates that students need to acquire the necessary skills and knowledge required for solving mathematical problems. The study investigated the impact of information and communication technology (ICT) on gender differentials in mathematics performance among secondary school students in Kwara State.…

This article examines how teachers at one elementary school made sense of their instructional practice after their school adopted a personalized learning platform for teaching mathematics. Data includes interviews (n = 21) with 12 teachers and administrators as well as recordings of 18 hours of professional learning sessions. The study…

This article presents the results of applying an educational sequence implemented with technological support on an LMS and focused on peer assessment that was designed specifically to address key concepts in statistics with first-year undergraduate students. Individualized information is available for a total of n=232 students to support the…

Math self-competence beliefs, namely, math self-efficacy and math self-concept, are crucial factors in sustaining math learning. Since there is a lack of literature on interventions targeting math self-competence beliefs in middle school students, the aim of this systematic review is to provide a narrative synthesis of the characteristics of…

As digital technologies become a commonplace in mathematics classrooms, they transform the ways students and teachers interact with mathematics. Students learn to use a technological tool for solving mathematical tasks through a process known as instrumental genesis. Teachers' support for this process is known as instrumental orchestration. In…

Although studies have investigated the enablers and barriers of digital teaching and learning of STEM, the integration of digital technologies into teaching geometry -- one of the main mathematical concepts, is frequently ignored and does not garner much scholarly attention. To fill this specific gap, this small-scale qualitative study explored…

The paper describes an implementation of research done over several years, by me and in some cases others, at Stanford University and elsewhere. The implementation comprised the design, building, testing, and marketing of a digital educational technology platform to provide a supplementary tool for explorative mathematics learning and assessment.

This article presents an instructional technology-based cycle model intended to support and facilitate the teaching and learning of mathematics, particularly calculus. The study used quantitative methods with quasi-experimental research that uses non-randomised assignments of the study group that are categorised into experimental and control…

This study extends prior research by manipulating both intervention and skill difficulty using a multiple baseline across participants design with changing phases in a virtual tutoring environment. Participants were four U.S. students from third and fifth grades for whom appropriate and challenging instructional targets were selected following…

This study explored the potential connections between secondary in-service (ISTs) and preservice (PSTs) mathematics teachers' anticipations and their noticing of student thinking in technology-mediated learning environments, a topic with limited prior research. Specifically, the study examined how teachers (ISTs and PSTs) anticipate student…

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…
