Lai, Maxine; Zax, Alexandra; Barth, Hilary – Developmental Science, 2018
Learning the meanings of Arabic numerals involves mapping the number symbols to mental representations of their corresponding, approximate numerical quantities. It is often assumed that performance on numerical tasks, such as number line estimation (NLE), is primarily driven by translating from a presented numeral to a mental representation of its…

Brooks, Neon B.; Barner, David; Frank, Michael; Goldin-Meadow, Susan – Cognitive Science, 2018
People frequently gesture when problem-solving, particularly on tasks that require spatial transformation. Gesture often facilitates task performance by interacting with internal mental representations, but how this process works is not well understood. We investigated this question by exploring the case of mental abacus (MA), a technique in which…

Bray, Wendy S.; Maldonado, Luz A. – Teaching Children Mathematics, 2018
A single fact-focused number-string discussion is unlikely to result in all students adopting more flexible and efficient fact strategies; however, these authors have found that repeated engagement in such discussions over time does promote student reasoning about relationships, which in turn leads to increased fact fluency. By cultivating a…

Kale, Ugur; Akcaoglu, Mete; Cullen, Theresa; Goh, Debbie; Devine, Leah; Calvert, Nathan; Grise, Kara – TechTrends: Linking Research and Practice to Improve Learning, 2018
Computational thinking is one of the skills critical for successfully solving problems posed in a technology driven and complex society. The limited opportunities in school settings to help students develop computational thinking skills underscores the need for helping teachers integrate it in their practices. Besides developing the knowledge of…

Uanhoro, James Ohisei; O'Connell, Ann A. – AERA Online Paper Repository, 2018
There have been increasing calls for applied researchers to see and utilize effect sizes as the primary outcomes of their research. However, this sometimes places a methodological burden on researchers whose primary interests are substantive. Motivated by a desire to help applied researchers better report effect sizes and their confidence…

Tang, Xiaodan; Yin, Yue; Lin, Qiao; Hadad, Roxana – AERA Online Paper Repository, 2018
Computational thinking (CT) has been recognized as an essential part of every child's education (Wing, 2006) and Bebras contest items have been frequently used to measure CT. Think alouds has emerged as a prominent method for identifying thought processes and correcting problems with assessments. As little research has examined validity evidence…

Swan, Daniel M.; Pustejovsky, James E. – Grantee Submission, 2018
Single-case designs are a class of repeated measures experiments used to evaluate the effects of interventions for small or specialized populations, such as individuals with low-incidence disabilities. There has been growing interest in systematic reviews and syntheses of evidence from single-case designs, but there remains a need to further…

Karabey, Burak – Australian Mathematics Education Journal, 2019
This study aims to introduce a method that is based on the relationship between numbers and geometry, which can be used to show the exact location of rational numbers on the number line, compare rational numbers, make calculations, and examine rational numbers conceptually through parallel lines. It is believed that this method will to contribute…

Baroutsis, Aspa; White, Sonia L. J.; Ferdinands, Ella; Goldsmith, William; Lambert, Elizabeth – Australian Primary Mathematics Classroom, 2019
Computational thinking can be defined as "solving problems, designing systems, and understanding human behaviour, by drawing on the concepts fundamental to computer science" (Wing, 2006, p. 33). There are strong links between computational thinking associated with coding and mathematical thinking (Wing, 2006). The digital technologies…

Melkonian, Vardges – PRIMUS, 2019
This paper discusses a game that can be used for introducing the binary representation of integers in an interactive and fun environment. The game is introduced in the way it is presented in an undergraduate Discrete Mathematics class. Variations of the game are discussed, particularly its extension to base-three representation of integers. It is…

Morano, Stephanie; Riccomini, Paul J.; Lee, Joo-Young – Learning Disabilities Research & Practice, 2019
Abstract Assessment results are used to investigate relations between performance on a fraction number line estimation task and a circular area model estimation task for students with LD in Grades 6-8. Results indicate that students' abilities to represent fractions on number lines and on circular area models are distinct skills. In addition,…

Liebscher, Eckhard; Michael, Ben – International Electronic Journal of Mathematics Education, 2019
In the paper a software solution is presented for the generation of instances of exercises. The focus is on education in mathematics but the approach can be adopted in other fields such as computer science and natural science. The present solution uses the R environment for the generation process and LaTeX for the content presentation. In the…

M.; Dionne, Ginette; Brendgen, Mara; Vitaro, Frank; Tremblay, Richard E.; Boivin, Michel; Kovas, Yulia – British Journal of Educational Psychology, 2019
Background: The number line task assesses the ability to estimate numerical magnitudes. People vary greatly in this ability, and this variability has been previously associated with mathematical skills. However, the sources of individual differences in number line estimation and its association with mathematics are not fully understood. Aims: This…

Latour, Austin W.; Peterson, David D.; Riner, Daniel D. – International Journal of Kinesiology in Higher Education, 2019
As a result of a Department of Defense (DoD) mandate, the U.S. Navy implemented its current body composition assessment (BCA) program in 1982. Despite the feasibility of the current program, its reliability, validity, and applicability have long since been called into question. As a result of these concerns, the Naval Health Research Center (NHRC)…

Kurniawan, Oka; Koh, Li Ling Apple; Cheng, Jermaine Zhi Min Cheng; Pee, Maggie – Journal of Chemical Education, 2019
Integrating knowledge across disciplines has been shown to be a challenging, and yet it is a necessary skill that university students need to develop. Students who are able to connect different concepts, perspectives, and angles of a given topic are generally more engaged and have better understanding. However, designing lesson plans or…
