Zhu, Liqi; Gigerenzer, Gerd – Cognition, 2006
Can children reason the Bayesian way? We argue that the answer to this question depends on how numbers are represented, because a representation can do part of the computation. We test, for the first time, whether Bayesian reasoning can be elicited in children by means of natural frequencies. We show that when information was presented to fourth,…

Williamson, Victoria – Mathematics Teaching Incorporating Micromath, 2007
In this article, the author describes her attempt to develop more interactive mental mathematics sessions. She observed that her students perceive the multiplication tables as a series of facts which are either known or not known, not as tools which could be used to derive other facts in a flexible manner. She therefore undertook the task of…

Carroll, William M. – School Science and Mathematics, 1996
Compares the results of a whole-class test on mental computation problems given to fifth graders who had been in a reform-based mathematics curriculum with those of students in a traditional mathematics curriculum. Reports that the students in the reform-based program performed much higher than the comparison group on all but one problem. (16…

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…

Reys, Barbara – Instructor, 1983
Students who can compute mathematical problems in their heads have learned a skill that is important for estimating and for understanding the number system. Practice activities that can help students master mental computation skills are described. (PP)

Anderson, John R.; Fincham, Jon M. – Cognitive Science, 2014
Multi-voxel pattern recognition techniques combined with Hidden Markov models can be used to discover the mental states that people go through in performing a task. The combined method identifies both the mental states and how their durations vary with experimental conditions. We apply this method to a task where participants solve novel…

Rea, Robert E.; French, James – Arithmetic Teacher, 1972
A study of activities in mental computation and in paper and pencil enrichment activities for sixth graders showed that both treatments produced increases in achievement test scores. Examples of both types of activities used are included. (DT)

Suzuki, Kouzi – Illinois Mathematics Teacher, 1995
Describes the use of a soroban, a base-10 computer which is a relative of the Chinese abacus, for developing concepts of number sense, place value, operation sense, and mental computation. Provides pictures of the soroban. (MKR)

Ullman, M.T.; Pancheva, R.; Love, T.; Yee, E.; Swinney, D.; Hickok, G. – Brain and Language, 2005
Are the linguistic forms that are memorized in the mental lexicon and those that are specified by the rules of grammar subserved by distinct neurocognitive systems or by a single computational system with relatively broad anatomic distribution? On a dual-system view, the productive -ed-suffixation of English regular past tense forms (e.g.,…

Olsen, James R. – Mathematics Teacher, 2015
After studying the Common Core State Standards for Mathematics (CCSSM) and brain-based learning research, James Olsen believes mental math instruction in secondary school mathematics (grades 7-12) and in teacher education programs needs increased attention. The purpose of this article is to share some keys for teaching mental math. Olsen also…
