Megan Rojo; Sarah G. King; Jenna Gersib; Christian T. Doabler – Learning Disability Quarterly, 2025
Competence with rational numbers is essential for mathematics proficiency in secondary mathematics. However, many students struggle with rational number concepts, and students with mathematics difficulties struggle even more. The purpose of this study was to examine the effects of an intervention that incorporated the use of explicit instruction…

Rickard Östergren; Ulf Träff; Jessica Elofsson; Hugo Hesser; Joakim Samuelsson – Scandinavian Journal of Educational Research, 2024
The study set out to explore different mathematical difficulties among 877 second-grade children and to test the effect of memorization versus conceptual practices with number combinations. It used a latent profile analysis of baseline measurements of digit writing speed, number combination fluency, multidigit calculation, and number sense skills…

Hitt, Fernando – North American Chapter of the International Group for the Psychology of Mathematics Education, 2020
We present the results of a research project on arithmetic-algebraic thinking that was carried out jointly by a team in Mexico and another in Quebec. The project deals with the concepts of variable and covariation between variables in the sixth grade at the elementary level and the first, second, and third years of secondary school--namely,…

Henderson, Peter; Hodgen, Jeremy; Foster, Colin; Kuchemann, Dietmar – Education Endowment Foundation, 2017
This guidance report focuses on the teaching of mathematics to pupils in Key Stages 2 and 3. It is not intended to provide a comprehensive guide to mathematics teaching. We have made recommendations where there are research findings that schools can use to make a significant difference to pupils' learning, and have focused on the questions that…

Jordan, Nancy C.; Hansen, Nicole; Fuchs, Lynn S.; Siegler, Robert S.; Gersten, Russell; Micklos, Deborah – Grantee Submission, 2013
Developmental predictors of children's fraction concepts and procedures at the end of fourth grade were investigated in a 2-year longitudinal study. Participants were 357 children who started the study in third grade. Attentive behavior, language, nonverbal reasoning, number line estimation, calculation fluency, and reading fluency each…

Mtetwa, David; Garofalo, Joe – Academic Therapy, 1989
The article identifies five incorrect beliefs about mathematics often held by students who have difficulty with mathematics. They include: the relative size of numbers is more important than the relationships between quantities; computation problems must be solved by using a step-by-step algorithm; mathematics problems have only one correct…

O'Brien, Thomas C. – School Science and Mathematics, 1971
Children may perform computational operations readily when dealing with physical materials, but may have difficulty dealing with representational stimuli (pictures of objects) or symbolic stimuli. Describes and illustrates the function of mediators in moving from physical to representational or symbolic stimuli. (PR)
