Empirical evidence for benefit? : Reviewing quantitative research on the use of digital tools in mathematics education

The benefit of using digital tools in education, and in mathematics education in particular, is subject to debate. To investigate this benefit, we focus on effect sizes on student achievement reported in reviews of experimental and quantitative studies. The results show significant positive effects with modest effect sizes. Possible causes for this are discussed and illustrated with one case study. We wonder if the review studies capture the subtlety of integrating digital tools in learning as much as qualitative studies do, and question their potential to address the “how” question. As a conclusion, a plea is made for replication studies and for studies that identify decisive factors through the combination of a methodologically rigorous design and a theoretical foundation in domain-specific theories from mathematics didactics

Uses of technology in lower secondary mathematics education : a concise topical survey

This topical survey provides an overview of the current state of the art in technology use in mathematics education, including both practice-oriented experiences and research-based evidence, as seen from an international perspective. Three core themes are discussed: Evidence of effectiveness; Digital assessment; and Communication and collaboration. The survey’s final section offers suggestions for future trends in technology-rich mathematics education and provides a research agenda reflecting those trends. Predicting what lower secondary mathematics education might look like in 2025 with respect to the role of digital tools in curricula, teaching and learning, it examines the question of how teachers can integrate physical and virtual experiences to promote a deeper understanding of mathematics. The issues and findings presented here provide an overview of current research and offer a glimpse into a potential future characterized by the effective integration of technology to support mathematics teaching and learning at the lower secondary level

Rhinoviruses

Picornaviruses, which include the human rhinoviruses (HRVs) and enteroviruses (EVs), are the most frequent cause of acute human illness worldwide. HRVs are the most prevalent cause of acute respiratory tract illnesses (ARIs) which usually commence in the upper respiratory tract (URT). ARIs are the leading cause of morbidity in children under 5 years and occur in all seasons. ARIs linked to HRV infections are associated with excessive and perhaps inappropriate antibiotic prescribing and with significant direct and indirect healthcare expenditure. ARI incidence is highest in the first 2 years of life, with up to thirteen episodes per year including up to six positive for an HRV, and it is not uncommon to average one infection per child-month
