Word problems play a crucial role in mathematics education. However, the authenticity of word problems is quite controversial.
In terms of the necessity of realistic considerations to be taken into account in the solution process, word problems have
been classified into two categories: standard word problems (S-items) and problematic word problems (P-items). S-items refer
to those problems involving the straightforward application of one or more arithmetical operations with the given numbers,
whereas P-items call for the use of real-world knowledge and real-life experience in the problem-solving process. This study
aims to explore how Chinese upper elementary school mathematics teachers think of the place and value of P-items in the elementary
mathematics curriculum. 相似文献

The purpose of this study was to investigate language related difficulties and the language of cognitive processes of English-Korean bilingual students in solving mathematics word problems. Qualitative case study research methodology was used to collect, analyze, and present data. The principle of purposeful sampling was used to select six English-Korean bilingual students. Different types of bilinguals revealed distinct patterns of difficulties and languages in solving mathematics word problems written in English and Korean. Children in the transition stage that is unstable and changing revealed more difficulties in solving the mathematics word problems overall.This article is a summary of doctoral dissertation under the direction of James W. Wilson at the University of Georgia. 相似文献

The purpose of the present study is to clarify the contributions of cognitive skills (nonverbal reasoning, language comprehension, working memory, attention, processing speed) and academic skills (mathematics facts retrieval, mathematics computation, mathematics vocabulary, reading comprehension) in performing mathematics word problems among elementary school students. With the two-stage meta-analytic structural equation modeling approach, I synthesized 112 correlation matrices from 98 empirical studies (N?=?111,346) and fitted the hypothesized partial mediation model. Overall, path analysis indicated that language comprehension, working memory, attention, mathematics vocabulary, and mathematics computation were unique predictors of word-problem solving. Subgroup analysis demonstrated different unique predictors for younger and older students to perform word problems (K-2nd grades versus 3rd–5th grades). Implications, limitations, and future directions are discussed.

Effects of consistency and adequacy of language information on understanding elementary mathematics word problems 总被引：3，自引：0，他引：3
Two types of elementary mathematics word problems involving different linguistic structures were devised to examine the understanding
and solution of these problems by 91 Grade 3, 4, and 5 children divided into “more able” and “less able” subgroups. One task
consisted of 12 consistent and 12 inconsistent language problems on the basic processes of addition, subtraction, multiplication
and division. Another task consisted of a total of 36 word problems with 12 items each containing adequate, inadequate, and
redundant information, respectively, for problem solution. Subsidiary tasks of general ability, vocabulary, reading comprehension,
mathematics concepts, reflection on mathematics learning, and working memory were also administered to provide estimates of
the contribution of these “nonmathematics” tasks to the solution of elementary mathematics problems. Analyses of variance
and covariance of group data showed significant main effects of grade, consistency, and adequacy of linguistic information
in problem solution. Word problems containing inconsistent information were more difficult than those with consistent information.
Further, word problems containing inadequate and redundant information were more difficult to classify, and for the children
to explain, than those items with just enough information. Interviews with 12 individual children provided further insight
into their strategies for problem solutions. Both cognitive and developmental perspectives are important for mathematics learning
and teaching for children with or without learning disabilities. 相似文献

This study, situated in a multilingual, English-medium educational context, draws on theory from mathematics and language education to capture teachers’ perspectives on the place of language in their mathematics pedagogy. The benchmark study explored this topic through surveying and interviewing teachers. Additionally, it sought to relate teachers’ views to their practice by focusing on observing three teachers’ mathematics lessons at primary one, three, and five. Findings are that mathematics teachers placed importance on teaching language, being specifically concerned with language as input and comprehension. They taught vocabulary and reading skills in supportive ways explicitly yet differently at the three grade levels. Particularly at the lower levels, teachers contextualised language in the concrete examples employed for mathematics teaching. At all three levels, prominence was given to teaching pupils how to read word problems as well as how to solve them. However, at primary three, a tension was observed between the two aims of teaching mathematical vocabulary and teaching the reading skills for word problems. This paper illustrates the tension and discusses its possible causes. 相似文献

From classifications of word problems in international discussion of elementary mathematics instruction as well as from conceptual elaborations of didactical analyses in Germany, a classification of semantic structures of one-step word problems involving multiplication or division is proposed, comprehending four main classes: Forming the n-th multiple of measurers, combinatorial multiplication, composition of operators, and multiplication by formula. This classification is more comprehensive and differentiated than the classifications of Vergnaud (1983), Nesher (1988), and Bellet al. (1989) — aiming at a better assignment between diverse contextual circumstances and conceptual demands of mathematics and at compatibility with the well-known semantic structures of addition and subtraction word problems. 相似文献

The purpose of this study was to examine effectiveness of paraphrasing interventions on mathematics word problem‐solving accuracy in third grade children (N = 72) at risk for mathematics disabilities (MD). Three instructional conditions directed students’ attention through paraphrasing, via writing, to different propositions within word problems. Students were randomly assigned to one of four intervention conditions: paraphrase question propositions (restate), paraphrase relevant propositions (relevant) and paraphrase all propositions (complete) or an untreated control. A mixed ANCOVA indicated that paraphrasing relevant and complete propositions significantly increased posttest accuracy when compared to the control and restate condition. Results from the study provide support for the effectiveness of paraphrasing interventions that directs students to restate/paraphrase propositions of mathematics word problems relative to the control condition. 相似文献
