Primary-level teachers can show their students that mathematics is all around them by turning classroom projects into opportunities for math practice. This across-the-curriculum activity gives pairs of students a problem-solving experience by having them figure out how to create journals with different numbers of pages. (SM)

States that problem-solving skills receive inadequate attention in many mathematics classrooms, and that preservice teacher-education programs can address the lack of instruction in problem solving. Provides rationale for teaching problem solving in the middle grades as an alternative to textbook exercises and worksheets and as a means of…

This study compared the effectiveness of 3 procedures for teaching 62 elementary students with learning disabilities to identify the correct algorithm in solving addition and subtraction word problems. The group receiving strategy teaching and sequencing practice problems and the group receiving strategy teaching only scored higher than…

While helping high school students develop statistical thinking, teachers need to engage them in all phases of investigative cycle. Students should master some of the nonmathematical elements of the cycle involved in identifying a problem, creating a plan of attack and gathering necessary data.

The conditions under which explicit instruction in checking, combined with worked examples, may be beneficial in learning how to translate sentences into algebraic equations was examined from the perspective of cognitive load theory. In two experiments it was shown that Grade 8 and 9 students were initially disadvantaged by the inclusion of a…

This paper reports research that focuses on student teachers' reflections on their learning process in a collaborative problem-solving context. One group of students with limited mathematical backgrounds worked on two problems in geometry without teacher intervention. We focus on two episodes from the group dialogues. In the first episode (section…

Each of the primary problems described in this article encourage children to "get into" the process of problem solving, and all can be introduced without written instructions. A demonstration by the teacher with large hands-on materials can involve all the children effectively and give him/her the opportunity to highlight key points and deal with…

The difficulties that primary students experience when dealing with real-world related word problems have been discussed extensively. These difficulties are not only related to complex, non-routine problems but already occur with respect to routine problems that involve the application of a simple algorithm. Due to difficulties with the…

The purpose of this study was to analyse secondary school students' (N = 16) computer-supported collaborative mathematical problem solving. The problem addressed in the study was: What kinds of metacognitive processes appear during computer-supported collaborative learning in mathematics? Another aim of the study was to consider the applicability…

The purpose of this study was to assess the effects of schema-broadening instruction (SBI), with and without explicit instruction in strategies for tackling the complexities involved in real-life (RL) math problems, on the math problem solving of third-grade students. Teachers (n = 30) were assigned randomly to 3 16-week conditions: control, SBI,…

Presents a problem which requires students to become familiar with the computation and interpretation of a non-parametric statistic for rank correlation. Purpose of problem is to help students to see meaningful application and to present a problem that does not have a text-book answer. (BR)

This study examined whether knowledge of arithmetic contributes to difficulties with equations. In Experiment 1, children (ages 7-11) completed tasks to assess their adherence to 3 operational patterns prevalent in arithmetic: (a) the strategy of performing all given operations on all given numbers, (b) the "operations=answer" problem structure,…

An engineering problem concerned with relating the coordinates of the centre of a spherical cutting tool to the actual cutting surface leads to a potentially rich example of problem-solving techniques. Basic calculus, Lagrange multipliers and vector calculus techniques are employed to produce solutions that may be compared to better understand…

A lot has been made of the topical puzzle Su Doku, with various claims that it can support development of mathematical abilities. The latest, in March this year, came from the Training and Development Agency when a giant puzzle was used to attract graduates into a career of maths teaching. A giant Su Doku puzzle toured busy city centres with the…

This article illustrates how the arithmetic series 1 + 2 + 3 + ... + n is pervasive in mathematical contexts as a powerful problem-solving tool.
