In the past decade, Computational Thinking (CT) education has received growing attention from researchers. Although many reviews have provided synthesized information on CT teaching and learning, few have paid particular attention to collaborative learning (CL) strategies. CL has been widely implemented in CT classes and has become the most…

There is an increasing interest in the integration of computational thinking (CT) in the K-12 curriculum. By integrating CT into other disciplines, the aim is to equip students with essential skills to navigate domain-specific challenges. This study conducts a systematic review of 108 peer-reviewed scientific papers to analyze in which K-12…

Reacts to an article published in a previous issue of this journal on the effects of graphing calculators and computer algebra systems (CAS) on students' manual calculation and algebraic manipulation skills. Considers the contribution made by Jean-Baptiste Lagrange to thinking about the role of CAS in teaching algebra. (ASK)

A program is given which offers students a chance to practice mental computation and judge the effects of various rules for formating output. (MNS)

Strategies for rapid mental computation are explained, including multiplying by 11 (or 21, 31, etc.); adding columns of numbers; and multiplying 2-digit numbers. Rapid mental computation is suggested as a motivator for investigating the underlying mathematical principles. (DB)

A set of three problem-solving programs designed as drills that give practice in mental arithmetic are reviewed. The programs are viewed to have several weaknesses in style, but are noted as worthy of consideration for purchase. The material is designed to motivate students to practice all four basic operations. (MP)

Describes the basic and exceptional calculation abilities of a calculating prodigy whose performances were investigated in single- and multi-digit number multiplication, numerical comparison, raising of powers, and short-term memory tasks. Shows how his highly efficient long-term memory storage and retrieval processes, knowledge of calculation…

Describes two main categories of mental activity used by students in mathematics classes: mental mathematics and mathematical thought. Calls for the continuation of teaching mental mathematics and asks for the inclusion of mathematical thought in the national curricula. (MKR)

Four worksheets and teaching suggestions are presented, with the focus on mental computation for levels 2-3; factors, levels 3-4; and nonroutine problems, levels 5-6 and 7-8. (MNS)

Example of magic tricks that can be used as an integral part of various lessons in arithmetic and algebra are given. Their mathematical basis is also discussed. (MNS)

An example of an unrealistic "real world" problem from the National Assessment of Educational Progress highlights a comparison of school and "folk" mathematics. The failures of typical problems taught in school and some suggested remedies are featured. (MP) Aspect of National Assessment (NAEP) dealt with in this document:…

Presents concluding remarks to a symposium, "The Social Organization of Knowledge and Practice." Focuses on high aptitude of persons in everyday situations to solve problems and make decisions. Addresses three questions: (1) What happens when a problem-solver reaches a situation involving calculation? (2) How does learning transfer take place? and…

The material is designed for pupil practice in: (1) associating numerals with sets of objects and finding sums of two or three numbers; (2) subtracting, one- and two-digit numbers with some regrouping; (3) mental computation using the basic operations; and (4) using combinations of basic operations with whole numbers and decimals. (MP)

A study of 255 fifth graders and 177 eighth graders from 12 randomly chosen Mexican schools was conducted to identify and characterize the students' computational estimation skills and strategies. Data from computational estimation tests and selected interviews revealed that Mexican students employed general estimation processes similar to U.S.…

First, fourth, seventh, and tenth graders were timed when solving simple and complex addition problems, then were presented similar problems in untimed interviews. Manipulation of confusion between addition and multiplication, where multiplication answers were given to addition problems (3 + 4 = 12) indicated an interrelatedness of these…
