Children's construction of mathematical knowledge in solving novel isomorphic problems in concrete and written form

The focus of this article is children's construction and analogical transfer of mathematical knowledge during novel problem solving, as reflected in their strategies for dealing with isomorphic combinatorial problems presented in “hands-on” and written form. Case studies of low- and high-achieving 9-year-olds in school mathematics serve to illustrate a general progression through three identified stages of strategy construction. The important role of domain-general strategies in this development is highlighted. Included in the study's findings is the fact that achievement level in school mathematics does not predict children's attainment of the third stage, as is evidenced by the low-achieving student's construction of sophisticated combinatorial knowledge and the high-achieving student's failure to do so. Children's ability to recognize structural correspondence between the two isomorphic problem sets and the extent to which this facilitates problem solution are also reported.     

Mathematics in Children's Thinking

The human mind inevitably comprehends the world in mathematical terms (among others). Children's informal and invented mathematics contains on an implicit level many of the mathematical ideas that teachers want to promote on a formal and explicit level. These ideas may be innate, constructed for the purpose of adaptation, or picked up from an environment that is rich in mathematical structure, regardless of culture. Teachers should attempt to uncover the mathematical ideas contained in their students' thinking because much, but not all, of the mathematics curriculum is immanent in children's informal and invented knowledge. This mathematical perspective requires a focus not only on the child's constructive process but also on the mathematical content underlying the child's thinking. Teachers then can use these crude ideas as a foundation on which to construct a significant portion of classroom pedagogy. In doing this, teachers should recognize that children's invented strategies are not an end in themselves. Instead, the ultimate goal is to facilitate children's progressive mathematization of their immanent ideas. Children need to understand mathematics in deep, formal, and conventional ways.     

Picture Books as an Impetus for Kindergartners' Mathematical Thinking

Although there is evidence that the use of picture books affects young children's achievement scores in mathematics, little is known about the cognitive engagement and, in particular, the mathematical thinking that is evoked when young children are read a picture book. The focus of the case study reported in this article is on the cognitive engagement that is facilitated by the picture books themselves and not on how this engagement is prompted by a reader. The book under investigation, Vijfde zijn [Being Fifth], is a picture book of high literary quality that was not written for the purpose of teaching mathematics. The story is about a doctor's waiting room and touches on backwards counting and spatial orientation only tacitly as part of the narrative. Four 5 year olds were each read the book by one of the authors without any questioning or probing. The reading sessions took place in school, outside the classroom. A detailed coding framework was developed for analyzing the children's utterances that provided an in-depth picture of the children's spontaneous cognitive engagement. Surprisingly, almost half the utterances were mathematics-related. The findings of the study support the idea that reading children picture books without explicit instruction or prompting has large potential for mathematically engaging children.     

Reflective Tutoring: Insights into Preservice Teacher Learning

An undergraduate seminar was designed to help preservice teachers focus on students' learning. Preservice teachers planned and conducted weekly tutoring sessions with fourth graders and discussed their experiences in weekly discussions. The author investigated what preservice teachers learned about teaching mathematics from their focus on students' learning of mathematics. The author examined the tasks that preservice teachers posed to children, the questions they asked of children, and the reflections they wrote about their experiences. The article describes what the preservice teachers learned from their experiences and provides insights into their knowledge and skills for developing children's mathematical power.     

Teaching children to add and subtract

At a 1980 conference, leading mathematics educators synthesized previous knowledge on children's early understanding of addition and subtraction and proposed central parameters for future research in these areas form a cognitive science perspective. We have, since 1980, increased our knowledge about how children learn to add and subtract, but we need to know more about the best ways for teachers to guide children as they construct knowledge of addition and subtraction.In this article, we review several studies that focus on an enhanced role for teachers in enabling children to learn addition and subtraction. These studies describe efforts that have been made to teach children to use diagrams and mediational representations, number sentences, or algorithms and procedures. The studies report improvement in children's problem-solving performance, but the impact of the efforts described on children's conceptual understanding is less clear. Thus, we analyze this research, pose questions on the relationship of instruction to children's knowledge construction, and propose a research agenda that we believe will enable us to understand how teaching can best help children learn to add and subtract.     

Immigrant parents’ perspectives on their children’s mathematics education

This paper draws on two research studies with similar theoretical backgrounds, in two different settings, Barcelona (Spain) and Tucson (USA). From a sociocultural perspective, the analysis of mathematics education in multilingual and multiethnic classrooms requires us to consider contexts, such as the family context, that have an influence on these classrooms and its participants. We focus on immigrant parents' perspectives on their children's mathematics education and we primarily discuss two topics (1) their experiences with the teaching of mathematics, and (2) the role of language (native language and second language). The two topics are explored with reference to the immigrant student's or their parents' former educational systems (the “before”) and their current educational systems (the “now”). Parents and schools understand educational systems, classroom cultures and students' attainment differently, as influenced by their sociocultural histories and contexts.     

Teachers' funds of knowledge and the teaching and learning of mathematics in multi-ethnic primary schools: Two teachers' views of linking home and school

In this paper we explore two teachers' views on the role(s) of parents, the local community and children's home lives in the learning of mathematics in primary school. We use Moll and Greenberg's concept of ‘funds of knowledge’ and apply it to the case studies of two teachers working in the UK context. Issues of teachers' professional experience, ethnicity, class and gender emerge as significant in examining similarities and differences in the teachers' beliefs, understandings and practices in the area of linking home and school. We end with a discussion of some implications for teacher education and professional development.     

Mother and Child Emotions during Mathematics Homework

Mathematics is often thought of as a purely intellectual and unemotional activity. Recently, researchers have begun to question the validity of this approach, arguing that emotions and cognition are intertwined. The emotions expressed during mathematics work may be linked to mathematics achievement. We used behavioral measures to identify the emotions expressed by U.S. mothers and their 11-year-old children while solving pre-algebra tasks in the home. The most notable positive emotions displayed by mothers and children included positive interest, affection, joy, and pride, whereas the most notable negative emotions expressed included tension, frustration, and distress. Reflecting the social aspects of doing homework together, mothers' and children's emotions were highly correlated. Independent of pre-existing differences in knowledge, children's emotions were associated with their performance on a mathematics post-test: tension was linked to poorer performance while positive interest, humor, and pride were linked to better performance. We found no evidence of gender differences in the emotions while working the tasks, although boys responded with more tension following an incorrect solution than did girls.     

Revisiting mathematical problem solving and posing in the digital era: toward pedagogically sound uses of modern technology

The availability of sophisticated computer programs such as Wolfram Alpha has made many problems found in the secondary mathematics curriculum somewhat obsolete for they can be easily solved by the software. Against this background, an interplay between the power of a modern tool of technology and educational constraints it presents is discussed. Using topics from algebra (equations) and elementary number theory (summation of powers of integers), the paper suggests ways of developing problems that are both technology-immune and technology-enabled in the sense that whereas software can facilitate problem solving, its direct application is not sufficient for finding an answer. Stemming from the author's work with secondary mathematics teacher candidates, this paper highlights the appropriate use of technology as support system for multiple ways of knowing and knowledge construction in the modern classroom.     

Empowering Families in Hands‐on Science Programs

Parental involvement in schools has been documented as a positive influence on children's achievement, attendance, attitudes, behavior, and graduation rate, regardless of cultural background, ethnicity, and socioeconomic status ( National Parents and Teachers Association, 1998 ). Unfortunately, it has been difficult in today's world of working parents to get them actively involved in science, mathematics, and technology programs and to maintain this involvement in upper‐elementary and secondary schools. This study reports on the Science: Parents, Activities, and Literature project's attempt to get parents productively involved in their children's hands‐on science program. The results illustrate that (a) parents will become involved and they find their involvement a positive experience, (b) teachers appreciate parents' contributions as an instructional resource, and (c) students perceive the increased parental involvement positively.     

Language Influence on Children's Cognitive Number Representation

This study examined the effect of language on children's cognitive representation of number. The sample for the study consisted of 90 Arabic speaking children with a mean age of 80 months. Children were interviewed individually and asked to represent written two‐digit numbers using base‐10 blocks. A new approach for testing the linguistic relativity hypothesis was used. The results of the study revealed that language played an important role in children's cognitive number representation. On the other hand, the results support the argument that the instructions given with the task alter children's performance on it. This study suggests that language may explain the cross‐cultural differences in mathematics achievement. However, the disadvantage that the language might place on children can be overcome with well‐planned instruction.     

A case study of pedagogy of mathematics support tutors without a background in mathematics education

This study investigates the pedagogical skills and knowledge of three tertiary-level mathematics support tutors in a large group classroom setting. This is achieved through the use of video analysis and a theoretical framework comprising Rowland's Knowledge Quartet and general pedagogical knowledge. The study reports on the findings in relation to these tutors’ provision of mathematics support to first and second year undergraduate engineering students and second year undergraduate science students. It was found that tutors are lacking in various pedagogical skills which are needed for high-quality learning amongst service mathematics students (e.g. engineering/science/technology students), a demographic which have low levels of mathematics upon entering university. Tutors teach their support classes in a very fast didactic way with minimal opportunities for students to ask questions or to attempt problems. It was also found that this teaching method is even more so exaggerated in mandatory departmental mathematics tutorials that students take as part of their mathematics studies at tertiary level. The implications of the findings on mathematics tutor training at tertiary level are also discussed.     

Problem Solving: Teachers' Perceptions,Content Area Models,and Interdisciplinary Connections

Features of common problem-solving models in mathematics and science, as well as those found in business and industry today, are discussed. Commonalties in the models are used to advance a case for interdisciplinary or integrated instruction in mathematics, science and technology. The Integrated Mathematics, Science and Technology (IMaST) program's problem-solving model is presented as an example of a curriculum project that draws upon the commonalties in the problem-solving models as a basis for a seventh grade integrated curriculum.     

Exploring Fractal Geometry With Children

The intent of this article is to heighten elementary school teachers', teacher educators', and teacher-education researchers' awareness of possible applications of fractal geometry with children and, subsequently, to initiate a discussion about the appropriateness of including this new mathematics in the elementary curriculum. Activities for exploring children's thinking and understanding relative to (a) describing, identifying, and measuring fractal patterns and (b) the attribute of self-similarity in some fractal sets are presented, as are recommendations for future research.     

Motivations and meanings of students' actions in six classrooms from Germany, Hong Kong and the United States

This article presents an analysis of about 100 interviews with students from eight-grade classrooms in Berlin, Hong Kong and San Diego that reconstructs student motivations and the meanings they attribute to classroom activities. The data of the six classrooms were produced in the Learner's Perspective Study (LPS). The LPS is an international collaboration of researchers investigating practices in eighthgrade mathematics classrooms in 13 countries. Although not the central focus of the research, the case study of six classrooms revealed a variety of students' beliefs and perceptions, which are the focus of this article. These correspond to the possibilities the classroom practices offer. The study also reveals some similarities among student motives and concerns across classrooms. The findings are an important reminder that basing a curriculum upon an alternative vision calls for changing mathematical content as well as the social relations that are established through teaching methods and principles of evaluation.     

Prospective Teachers' Perspectives on Mathematics Teaching and Learning: Lens for Interpreting Experiences in a Standards‐Based Mathematics Course

In a mathematics course for prospective elementary teachers, we strove to model standards‐based pedagogy. However, an end‐of‐class reflection revealed the prospective teachers were considering incorporating standards‐based strategies in their future classrooms in ways different from our intent. Thus, we drew upon the framework presented by Simon, Tzur, Heinz, Kinzel, and Smith to examine the prospective teachers' perspectives on mathematics teaching and learning and to address two research questions. What perspectives on the learning and teaching of mathematics do prospective elementary teachers hold? How do their perspectives impact their perception of standards‐based instruction in a mathematics course and their future teaching plans? Qualitative analyses of reflections from 106 prospective teachers revealed that they viewed mathematics as a logical domain representative of an objective reality. Their instructional preferences included providing firsthand opportunities for elementary students to perceive mathematics. They did not take into account the impact of a student's conceptions upon what is learned. Thus, the prospective teachers plan to incorporate standards‐based strategies to provide active experiences for their future elementary students, but they fail to base such strategies upon students' current mathematical conceptions. Throughout, the need to address prospective teachers' underlying perspectives of mathematics teaching and learning is stressed.     

A Tutorial Program: Collaboration Between Preservice and Inservice Teachers

Many elementary school teachers face severe time constraints working individually with students who need extra help or attention in mathematics. Sometimes, children who need this attention do not receive it. At the same time, critics of teacher education programs contend that preservice teachers do not receive enough hands-on experience teaching children. The Mathematics Tutorial Program is one attempt to address both of these issues. In this program, elementary grade children are identified by their classroom teachers as needing extra help in mathematics. They are paired with preservice elementary school teachers. Each preservice teacher tutors one or more elementary children for two 30-minute sessions each week for 6 to 24 weeks. They use manipulatives and a hands-on approach. The tutors reported professional gains from their contacts with classroom teachers, mathematics educators, and elementary children. Classroom teachers involved with the program commented on the children's improved selfesteem and confidence in mathematics. The children eagerly looked forward to the time with their tutors.     

An Integrated Research on Children's Construction of Meaningful,Symbolic, Partitioning-related Conceptions and the Teacher's Role in Fostering That Learning

A teaching experiment was conducted with two fourth graders to study the co-emergence of teaching and children's construction of fraction knowledge. The children's learning, i.e., modifications in their fraction schemes, was fostered through working on tasks in a computer microworld. The children advanced from thinking about a unit fraction as one of several equal parts in a whole (the equipartitioning scheme) to operating with a unit fraction as a symbolized, iterable part the magnitude of which is based on the numerosity of the partitioned whole (the partitive fraction scheme). The paper interweaves an analysis of children's construction of partitioning-related symbolic conceptions of fractions with an analysis of the teaching—planning and using tasks—that fosters such an advancement by introducing fraction words and numerals in the context of the children's partitioning activities.     

Preservice Teachers' Analysis of Children's Work to Make Instructional Decisions

Teaching is an interactive process in which teachers gather information, analyze the results, and construct a response based on this diagnosis ( Cooney, 1988 ). Considering alternatives in constructing a response, that is, making an instructional decision, is of great importance in teaching. How might mathematics teacher educators provide experiences for preservice teachers to begin the development of this skill? In an attempt to determine how these experiences might reveal the level of understanding preservice teachers have in regards to children's mathematical thinking, a study was conducted over three semesters. During the mathematics methods course, preservice teachers were involved in analyzing children's work through the review and discussion of several samples. They were required to determine the error pattern, discuss what might have lead to this misconception, and suggest appropriate instructional strategies that might help this student. Although most preservice teachers could correctly identify the computational error patterns, they had difficulty in determining what might have led to the misconceptions and proposing effective instructional strategies.
