Students with mathematics difficulty, especially students with disabilities and emergent bilinguals, require careful consideration during word-problem instruction. Word problems that include relational terms such as more but are not easily solved using the implied operation (i.e., addition) can be particularly challenging. First, we summarize a…

A theoretical model describing young students' (Grade 3) arithmetic-algebraic structure sense was formulated and validated empirically (n = 130), hypothesizing that young students' arithmetic-algebraic structure sense consists of five distinct but correlated factors; structure in numerical equivalence and word-problem modeling, structure in…

METRICS was a 5-year grant program funded by the U.S. Department of Education designed to immerse elementary school students in computer science. METRICS components included 1) creation and implementation of rigorous computer science curriculum units and assessments to support STEM coursework connected across all subjects through problem-based…

This paper is the third in a series of Analytical Insights papers, which provide accessible, up-to-date analysis of educational datasets. The insights in this paper are drawn from the latest National Assessment Program Literacy and Numeracy (NAPLAN) and Longitudinal Literacy and Numeracy in Australia (LLANIA) data to discuss student participation…

This study examines two longstanding but thinly evidenced claims regarding credentialing requirements for teachers in the early grades (pre-K, K, 1, 2, and 3): 1) that elementary education (ELED) educator standards, under which many U.S. early grade teachers are prepared, address early instructional practices less adequately than early childhood…

This paper is the first in a series of Analytical Insights papers, which provide accessible, up-to-date analysis of educational datasets. This insights paper draws on the latest National Assessment Program Literacy and Numeracy (NAPLAN) data to discuss student participation and engagement with the tests -- factors which impact the quality and…

Research has demonstrated strong relations between spatial skill and mathematics across ages and in both typical and atypical populations, suggesting that a significant proportion of variance in mathematics performance can be explained by variance in spatial skill. Why do these relations exist and how do they develop? Studies of dimensionality in…

In an innovative, progressive school, students were asked to solve a fairly routine mathematical problem using real money in a "real-world" scenario. Even though the school values students' ideas, the reaction of the teacher to one student's alternative modelling of the problem suggests that he was expecting a particular answer to be…

Though research on effective instruction in math word problem solving is prominent at the middle and secondary levels, much less work has been done in elementary grades. In this article, we review the research on varied problem-solving instructional interventions at the third-grade level for students across ability levels. Third grade was chosen…

The interaction analysis presented by Kim and Roth examines nine students, their teachers, the learning task and materials in a mixed second and third grade science classroom during the school day. In the research narrative readers are introduced to two resourceful and creative groups of students as they work on a task assigned by their…

"What do you do with the remainder when you divide?" Mrs. Thompson asked her third-grade students. They replied with such comments as, "You can't share that, because they won't be equal!" and "It's not going to come out even because you can't do that!" These answers were consistent with third- and fourth-grade student performance in a pretest and…

While there is widespread agreement on the importance of incorporating problem solving and reasoning into mathematics classrooms, there is limited specific advice on how this can best happen. This is a report of an aspect of a project that is examining the opportunities and constraints in initiating learning by posing challenging mathematics tasks…

Solving word problems is a difficult task for students at-risk for or with learning disabilities (LD). One instructional approach that has emerged as a valid method for helping students at-risk for or with LD to become more proficient at word-problem solving is using schemas. A schema is a framework for solving a problem. With a schema, students…

This study builds on two lines of research that have so far developed largely separately: the use of additive methods to solve proportional word problems and the use of proportional methods to solve additive word problems. We investigated the development with age of both kinds of erroneous solution methods. We gave a test containing missing-value…

The article begins with a brief overview of the situation throughout the world regarding problem solving. The activities of the ProMath group are then described, as the purpose of this international research group is to improve mathematics teaching in school. One mathematics teaching method that seems to be functioning in school is the use of open…
