Digital technology in mathematics education: Why it works (or doesn't)

The integration of digital technology confronts teachers, educators and researchers with many questions. What is the potential of ICT for learning and teaching, and which factors are decisive in making it work in the mathematics classroom? To investigate these questions, six cases from leading studies in the field are described, and decisive success factors are identified. This leads to the conclusion that crucial factors for the success of digital technology in mathematics education include the design of the digital tool and corresponding tasks exploiting the tool's pedagogical potential, the role of the teacher and the educational context

Webbing and orchestration. Two interrelated views on digital tools in mathematics education

The integration of digital tools in mathematics education is considered both promising and problematic. To deal with this issue, notions of webbing and instrumental orchestration are developed. However, the two seemed to be disconnected, and having different cultural and theoretical roots. In this article, we investigate the distinct and joint journeys of these two theoretical perspectives. Taking some key moments in recent history as points of de- parture, we conclude that the two perspectives share an importance attributed to digital tools, and that initial differences, such as different views on the role of digital tools and the role of the teacher, have become more nuances. The two approaches share future chal- lenges to the organization of teachers'collaborative work and their use of digital resources.Comment: Teaching Mathematics and its Applications (2014) to be complete

This paper describes a classroom experiment on the use of digital technology in initial algebra. Indonesian grade seven students of 12-13 year-old took part in a four session teaching sequence on beginning algebra enriched with digital technology, and in particular applets embedded in the Digital Mathematics Environment. The intervention aimed to improve students’ conceptual understanding and procedural skills in the domain of equations in one variable. The qualitative analysis of written and digital student work, backed up with video observations during the experiment, reveal that the use of digital technology affects student thinking and strategies dealing with equations and with related word problems. Practical and theoretical consequences of the results are discussed

La tecnología digital en educación matemática: por qué funciona (o no)

The integration of digital technology confronts teachers, educators and researchers with many questions.

Para investigar es-tas cuestiones, se describen seis casos de estudio prominentes en el área, y se identifican los factores decisivos para el éxito. Esto lleva a la conclusión de que los factores cruciales para el éxito de la tecnología digital en la educación matemática incluyen el diseño de la herramienta digital y de las tareas apropiadas que exploren el potencial pedagógico de la herramienta, el papel del profesor y el contexto educativo

The integration of digital technology into secondary mathematics education is not yet a widespread success. As teachers are crucial players in this integration, an important challenge is not only to attract early adopters, but also to support mid-adopting teachers in their professional development on this point. The questions addressed in this Chapter are: which practices such mid-adopting teachers develop when starting to use technology in their mathematics classroom; and how these practices change over time while engaging in a project with colleagues and researchers. To answer these questions, theoretical notions of instrumental orchestration, TPACK and community of practice underpin the case study of two mathematics teachers from a group of twelve, who engaged in a project on technology-rich teaching. The data includes lesson observations, blogs and results from questionnaires. The results show the type of teaching practices the teachers develop and the changes in these practices. Even if these changes are modest and the impact of the community is limited, the teachers clearly became more confident in integrating technology in their teaching

Instrumentation schemes for solving systems of linear equations with dynamic geometry software

In this paper we focus on the link between the use of dynamic geometry software and student understanding for the solution of systems of linear equations from an instrumental genesis perspective. Three task-based interviews were conducted with an undergraduate linear algebra student majoring in mathematics education and proficient in using dynamic geometry software. Data included video recordings, student written work and screen recordings. The data analysis was guided by the theoretical lens of instrumental genesis, to elaborate on how student thinking was shaped by the use of the digital artefacts. The digital technology supported the participant’s solution steps and over time the student developed four interrelated instrumentation schemes, which are parameter scheme, combined algebra and geometry scheme, the intersection of figures scheme and echelon form scheme.publishedVersio

Didactical engineering in France; an insider’s and an outsider’s view on its foundations, its practice and its impact

International audienceThe notion of didactical engineering has influenced and characterized contemporary research in mathematics education in France to an important extent. In this paper, we address the following from an insider’s and an outsider’s perspective: (1) the way this notion is theoretically grounded, (2) the kinds of design research practices has it led to and is leading to, and (3) the way it relates to the design research paradigm. As a conclusion, we highlight similarities and differences between the two perspectives and recommend further discussions to the benefit of both didactical engineering from an insider’s and an outsider’s perspective

Aprender matemáticas en un entorno de álgebra computacional: los obstáculos constituyen oportuniades

Utilizar álgebra computacional no es tan fácil como puede parecer. Frecuentemente, los estudiantes encuentran obstáculos mientras trabajan en un entorno de álgebra computacional. En este artículo se distinguen los obstáculos globales y los locales, y se identifican los de ambas categorías. La teoría de la instrumentación proporciona un marco para interpretar el obstáculo como un desequilibrio entre los aspectos conceptual y técnico de un esquema de instrumentación. Se argumenta que explicitar los obstáculos y tratar de superarlos, conduce al desarrollo conceptual. En consecuencia, los obstáculos constituyen oportunidades de aprendizaje

Designing an instrument to measure the development of techno-mathematical literacies in an innovative mathematics course for future engineers in STEM education

Techno-mathematical Literacies (TmL), which are defined as a combination of mathematical, workplace and ICT knowledge, and communicative skills, are acknowledged as important learning goals in STEM education. Still, much remains unknown about ways to address them in teaching and to assess their development. To investigate this, we designed and implemented an innovative course in applied mathematics with a focus on Techno-mathematical Literacies for 1st-year engineering students, and we set out to measure the learning effect of the course. Because measuring TmL is an uncharted terrain, we designed tests that could serve as pre- or posttests. To prevent a test learning effect, we aimed to design two different but equally difficult tests A and B. These were assigned randomly to 68 chemistry students, as a pretest, with the other one serving as posttest after the course. A significant development in TmL was found in the B-pre group, but not in the A-pre group. Therefore, as a follow-up analysis we investigated whether the two tests were equally difficult and searched for possible explanations. We found that test B was indeed perceived as more difficult than test A, but also that students who were assigned B (pre) were previously higher achieving than A (pre), and a sound mastery level of basic skills that ground the higher-order TmL seemed necessary. Furthermore, as TmL are very heterogenous by nature, some of them are easier learned and measured than others. Based on the results, we propose ways of testing TmL, which should be validated in future research
