Learning Multi‐unit Number Concepts and Understanding Decimal Place Value

Research indicates that many errors in secondary school mathematics can be attributed to lack of understanding of decimal place value. Recently it has been suggested that this arises from an underlying weakness in integer place value concepts and perception of multidigit numbers in unitary terms rather than base ten, multi‐unit structures. Development of place value and multidigit number concepts was examined in individual interviews with 262 primary school pupils, aged between 7 and 12 years, using subjects’ concrete representations of written numerals and associated verbal explanations. Almost all the children had some understanding of integer place value; most older children had multi‐unit concepts of three‐ or four‐digit numbers; but two‐digit numbers, especially values of 20 or less, were frequently perceived in terms of units by all age groups. This was particularly common for the value ten where 55% of subjects displayed unitary concepts. Implications for understanding and teaching decimal place value are discussed.     

Assessing and Promoting Self‐Regulated Strategy Use

College counselors can assist students in enhancing their academic performance by assessing student self‐regulated strategies. Key aspects of self‐regulated strategy use (SRSU) are identified, and a semistructured interview to assess SRSU is presented. The rich data collected in the interview can assist the counselor in designing academic counseling interventions consistent with the needs and life situation of the individual student.     

Reader,Word, and Character Attributes Contributing to Chinese Children’s Concept of Word

Concept of word—the awareness of how words differ from nonwords or other linguistic properties—is important to learning to read Chinese because words in Chinese texts are not separated by space, and most characters can be productively compounded with other characters to form new words. The current study examined the effects of reader, word, and character attributes on Chinese children’s concept of word in text. A total of 164 fifth-grade Chinese children participated in this study. Concept of word was measured by children’s lexical decisions about words and nonwords embedded in strings of characters. Cross-classified multilevel logistic models showed that reader attributes, including reading comprehension, vocabulary knowledge, and morphological awareness, interacted with certain word or character attributes in predicting children’s lexical decisions about words or nonwords. This study sheds light on the complex relationships between reader, word, and character attributes in the formation of concept of word in Chinese.     

如何与人相处

1. Keep skid chains on your tongue ;always say less than you think.Cultivate a low,persuasive voice.How you say it counts more than what you say. 2. Make promises sparingly,and keep them faithfully,no matter what it costs. 3. Never let an opportunity pass to say a kind and encouraging word to or about somebody.Praise good work,regardless of who did it.If criticism is needed,criticize helpfully, never spitefully. 4. Be interested in others,their pursuits,their work,their homes and families. Make merry with those who rejoice;with those who weep,mourn.Let everyone you meet,however humble,feel that you     

A survey of antecedents of attitudes toward science

Relationships among attitudes of students toward science, as measured by the WASP (Wareing Attitudes Toward Science Protocol), perceived antecedents of such attitudes, and class achievement or performance indicated by reported grades were investigated for a survey sample of 1,740 students in 87 high school science classes from five communities. Additionally, students' self-reported number of tests administered in a given course, perceived rewards, degree of stress, and internal structure of the course were examined as potential predictor variables. Results indicate a significant correspondence between report card grades, degree of structure, degree of stress, gender, degree of rewards, number of tests, and students' attitudes toward science.     

Child care choices: A longitudinal study of children,families and child care in partnership with policy makers

Child Care Choices is an example of new early childhood research based on a relationship between policy makers and researchers. It is also an example of large-scale longitudinal team-based research into early childhood in Australia. The ongoing study addresses the professional problem for practitioners and policy makers of the increasing use of multiple care settings and changes to care arrangements in the early years and their possible impacts on child development. The project will follow an initial sample of 693 families with a child aged from birth to three years over a three-year period. An ecological framework is used to include the influences on child development of characteristics of the children and their families, their city or country location, as well as their childcare history and current care arrangements. Development is measured in terms of children’s health, motor development, social and emotional development, language and communication as well as emerging literacy and numeracy. The article discusses the unique features of the project in Australian early childhood research, its history, preliminary findings, and the potential of this kind of large-scale, longitudinal team-based research conducted in partnership with policy makers to contribute to policy as well as to theoretical debate.     

Educational performance or educational inequality: what can we learn from PISA about France and England?

This article evaluates PISA 2000 as a resource for providing information on educational attainment and inequality, focusing on France and England. Going beyond pupils' performance, it assesses levels of educational inequality by examining distributions of scores and the relationship between socio‐economic status and performance. This review raises methodological issues which could hamper the comparison of performance. The prioritising of ‘skills for life’ over curriculum‐based questions, together with PISA's sampling on the basis of pupils' age rather than their class/grade, works to the advantage of the English performance. The issue of low response rates in England is also raised and care is urged with regard to ranking the performance of France and England on the basis of these results. The article concludes that as a tool for comparing average performance PISA has drawbacks, but for assessing levels of inequality it is a useful resource.     

Children’s early numeracy in England,Finland and People’s Republic of China

This research investigated the similarities and differences between countries in young children’s early numeracy skills related to age, culture, and gender. The participants were five‐year‐old children from Beijing (People’s Republic of China), England, and Finland. The rationale for the cross‐cultural comparison originates from research results with older children showing that Asian children outperform children from America or Europe, and from the lack of such information concerning younger children. The results showed that in all locations older children performed better than the younger children. Cultural differences were found: young children from Beijing outperformed those from England and Finland in overall early numeracy performance, as well as in sub‐tests for understanding of quantities and relations (i.e. relational skills), and counting skills. Finnish children had better scores than English children in the whole early numeracy scale and in the relational scale. The results are discussed in relation to culture, instruction in preschools, and learning support at home, as well as the effects of language characteristics. The culture’s appreciation of and approach to mathematics learning in early childhood is a plausible explanation for the cross‐cultural differences found in this study.
