Chinese and Australian Year 3 Children's Conceptual Understanding of Science: A multiple comparative case study

Children have formal science instruction from kindergarten in Australia and from Year 3 in China. The purpose of this research was to explore the impact that different approaches to primary science curricula in China and Australia have on children's conceptual understanding of science. Participants were Year 3 children from three schools of high, medium and low socio-economic status in Hunan Province, central south China (n?=?135) and three schools of similar socio-economic status in Western Australia (n?=?120). The students' understanding was assessed by a science quiz, developed from past Trends in Mathematics and Science Study science released items for primary children. In-depth interviews were carried out to further explore children's conceptual understanding of living things, the Earth and floating and sinking. The results revealed that Year 3 children from schools of similar socio-economic status in the two countries had similar conceptual understandings of life science, earth science and physical science. Further, in both countries, the higher the socio-economic status of the school, the better the students performed on the science quiz and in interviews. Some idiosyncratic strengths and weaknesses were observed, for example, Chinese Year 3 children showed relative strength in classification of living things, and Australian Year 3 children demonstrated better understanding of floating and sinking, but children in both countries were weak in applying and reasoning with complex concepts in the domain of earth science. The results raise questions about the value of providing a science curriculum in early childhood if it does not make any difference to students' conceptual understanding of science.     

Designing Science Learning in the First Years of Schooling. An intervention study with sequenced learning material on the topic of ‘floating and sinking'

Research on learning and instruction of science has shown that learning environments applied in preschool and primary school rarely makes use of structured learning materials in problem-based environments although these are decisive quality features for promoting conceptual change and scientific reasoning within early science learning. We thus developed and implemented a science learning environment for children in the first years of schooling which contains structured learning materials with the goal of supporting conceptual change concerning the understanding of the floating and sinking of objects and fostering students' scientific reasoning skills. In the present implementation study, we aim to provide a best-practice example of early science learning. The study was conducted with a sample of 15 classes of the first years of schooling and a total of 244 children. Tests were constructed to measure children's conceptual understanding before and after the implementation. Our results reveal a decrease in children's misconceptions from pretest to posttest. After the curriculum, the children were able to produce significantly more correct predictions about the sinking or floating of objects than before the curriculum and also relative to a control group. Moreover, due to the intervention, the explanations given for their predictions implied a more elaborated concept of material kinds. All in all, a well-structured curriculum promoting comparison and scientific reasoning by means of inquiry learning was shown to support children's conceptual change.     

Exploring Estimation in Young Primary School Children

There is an increasing emphasis in mathematics education on the importance of estimation abilities in children. This study investigates the role of context upon primary‐aged children's estimation skills. Children in three age groups (from aged 5 to 8 years) were asked to carry out a range of estimation tasks involving distance, area and volume measurements. The tasks varied in type and complexity and were either of a ‘real‐world’ or ‘mathematics task’ form. In addition to performance measures the children's answers to questions on how they carried out the estimates were recorded and analysed. Quantitative and qualitative analyses found significant effects for context and child strategy. Estimates in contexts perceived as mathematical were different, both in that they changed with age and in their error patterns, from contexts involving perceptual‐motor skills. The children's answers highlight the importance of imagery and classroom experience. The results are discussed within a model of estimating.     

The Effects of an Age‐appropriate Intervention on Young Children's Understanding of Inheritance

ABSTRACT The present study explored 4(N = 22) and 7‐year‐olds’ (N = 24) under‐Standing of biological inheritance in cows and horses. An intervention technique adapted from Springer (1995) in which children are taught the basic facts of intrauterine development and birth, in story form, was used in an attempt to improve children's conceptual understanding of inheritance. All children were pre‐tested about inheritance and subsequently half were trained using the intervention (the others were controls). All children were post‐tested within a week of pre‐test, and about 4 weeks later completed delayed post‐tests. Results showed that at pre‐test there were significant age differences in both judgements and explanations of inheritance with 7‐year‐olds exhibiting more sophisticated biological reasoning. Surprisingly, there were no significant improvements for either age in judgements or explanations of inheritance as a function of the intervention at post‐test or delayed post‐test. The findings are discussed with reference to theoretical issues surrounding children's theory of inheritance and the implications for training studies.     

The “Batman Effect”: Improving Perseverance in Young Children

This study investigated the benefits of self‐distancing (i.e., taking an outsider's view of one's own situation) on young children's perseverance. Four‐ and 6‐year‐old children (N = 180) were asked to complete a repetitive task for 10 min while having the option to take breaks by playing an extremely attractive video game. Six‐year‐olds persevered longer than 4‐year‐olds. Nonetheless, across both ages, children who impersonated an exemplar other—in this case a character, such as Batman—spent the most time working, followed by children who took a third‐person perspective on the self, or finally, a first‐person perspective. Alternative explanations, implications, and future research directions are discussed.     

Question,Explanation, Follow‐Up: A Mechanism for Learning From Others?

This study explored differences in caregiver–child interactions following children's information‐seeking questions. Naturalistic speech from thirty‐seven 4‐year‐olds and their caregivers was used to explore children's information‐seeking questions, the caregiver's response, and children's subsequent follow‐up. Half of the families were low‐socioeconomic status (SES) and the other half were mid‐SES. Although children across socioeconomic groups asked a similar proportion of questions, mid‐SES caregivers offered significantly more explanatory responses to causal questions as well as more noncircular explanations than low‐SES caregivers. No differences were found in children's follow‐up to responses given to fact‐based questions; however, after hearing unsatisfactory responses to causal questions, mid‐SES children were significantly more likely to provide their own explanation. Such variability in caregiver–child interaction may have implications for subsequent learning.     

Making Meaningful: Intention in Children's Art Making

Children's art work has often been the subject of study by researchers seeking to gain insight into the role of art making in children's learning and development. However, rarely are children's own explanations of their art making used to inform these studies. Children's perceptions of their own art making are important for research and practice in art education, because their artistic experiences and motivations determine how they will engage in and respond to art making activities. This study used ethnographic methods to learn about the art making that took place over the course of one year in an elementary school art room, and to gain insight into the students' experiences and perceptions of art‐making activity. Data were analysed using a socio‐cultural framework. By asking children why they made art and exploring children's own explanations of their art making, this study reveals some of the important intentions that children bring to their artistic activity, and some of the ways that children make meaning through art making.     

Children's Temperament and Academic Skill Development During First Grade: Teachers' Interaction Styles as Mediators

The present study followed 156 Finnish children (M_age = 7.25 years) during the first grade of primary school to examine to what extent parent‐ and teacher‐rated temperament impacts children's math and reading skill development during the first grade, and the extent to which this impact would be mediated by teachers' interaction styles with the children. The results showed that the impact of children's low task orientation and negative emotionality on their math skill development was mediated via teachers' behavioral control and, among girls, also by psychological control. The negative impact of children's inhibition on math skill development, in turn, was not mediated via teachers' interaction styles. Temperament did not predict the children's reading skill development during first grade.     

Science in early years education: introducing floating and sinking as a property of matter

In the present study we test the effectiveness of a teaching intervention concerning the phenomenon of floating and sinking as a property of the matter the bodies are made of. The treatment, designed for children aged four to six years, comprises two units of hierarchically sequenced activities. The children experiment with objects having specifically designed characteristics aiming at shifting children's attention from the objects to the material(s) these are made of. Both solid and hollow objects were used. The activities were developed collaboratively by a researcher and early years teachers and were implemented by the teachers of the work group in their own public school classes in a sample of 104 children. Action research processes were used to optimise classroom practices. Teacher preparation took place within the work group before implementation. Concept cartoons were used for the children's final assessment. Analysis of classroom data recorded during the course of the activities showed gradual redirection of the children's attention from the objects to the materials of which they were made. The results of the post-instructional assessment revealed high percentages of pupils understanding the kind of material as the determining factor for the bodies' behaviour in water.     

Using Scaffolding Strategies to Promote Young Children’s Scientific Understandings of Floating and Sinking

The purposes of this study are to examine young children’s explanations of floating and sinking and to investigate how scaffolding strategies provided by a tutor could promote their scientific understandings. Fifteen 4-year-olds and fifteen 5-year-olds from a public kindergarten in northern Taiwan participated in this study. The children were interviewed before and after an instructional intervention to examine their understandings about how the weight, volume, and material of an object are related to sinking and floating. During the intervention, children manipulated objects made of different materials and were assigned to one of the three groups: scaffolding-material (provided with teaching scaffolding and allowed to see the materials of the objects), scaffolding (teaching scaffolding only), and material groups (seeing the materials only). In the first two groups, 16 teaching strategies based on six scaffolding principles were employed. Analyses of interviews showed that before the intervention, the 4-year-olds seemed to have a variety of explanations for sinking and floating and a majority of the 5-year-olds used weight as an explanation for floatation. After the intervention, both 4- and 5-year-olds in the scaffolding-material and scaffolding groups improved their understandings of floating and sinking. Particularly, three out of five 5-years-olds in the scaffolding-material group related the material of an object to its buoyancy and generalized their explanations to the objects made of the same material. The findings suggest that manipulative experiences alone might not be enough for children to further their understandings about floatation and that combining teaching scaffolding with children’s perceiving of the materials of objects is more effective. This study provides insight into how to support young children to learn science through effective teaching strategies.     

The Effect of Teachers' Memory‐Relevant Language on Children's Strategy Use and Knowledge

Building on longitudinal findings of linkages between aspects of teachers' language during instruction and children's use of mnemonic strategies, this investigation was designed to examine experimentally the impact of instruction on memory development. First and second graders (N = 54, M_age = 7 years) were randomly assigned to a science unit that varied only in teachers' use of memory‐relevant language. Pretest, posttest, and 1‐month follow‐up assessments revealed that although all participating children learned new information as a result of instruction, those exposed to memory rich teaching exhibited greater levels of strategic knowledge and engaged in more sophisticated strategy use in a memory task involving instructional content than did students exposed to low memory instruction. The findings provide support for a causal linkage between teachers' language and children's strategic efforts.     

Mothers' Acculturation and Beliefs About Emotions,Mother–Child Emotion Discourse,and Children's Emotion Understanding in Latino Families

Research Findings: We examined associations among Anglo acculturation, Latino enculturation, maternal beliefs, mother–child emotion talk, and emotion understanding in 40 Latino preschool-age children and their mothers. Mothers self-reported Anglo acculturation, Latino enculturation, and beliefs about the value/danger of children's emotions and parent/child roles in emotion socialization. Mother–child emotion talk was observed during a Lego storytelling task. Children's emotion understanding was measured using 2 age-appropriate tasks. Correlations showed that mothers' Latino enculturation was associated with mothers' stronger belief in guiding children's emotions and children's lower emotion understanding. Anglo acculturation was associated with mothers' lower belief that emotions can be dangerous and children's better emotion understanding. Mothers with a stronger belief in guiding children's emotions more frequently labeled emotions. Mothers with a stronger belief that emotions can be dangerous less frequently explained emotions. Regressions controlling for child age and maternal education demonstrated that mothers with a stronger belief that children can learn about emotions on their own and mothers with greater Latino enculturation had children with lower emotion understanding, whereas mothers with greater Anglo acculturation had children with better emotion understanding. Practice or Policy: Results suggest that understanding both family acculturation and family enculturation will be helpful for early childhood researchers and educators seeking to assess and promote children's socioemotional development.     

Complexity of reasoning about children's development: Links with teacher‐preparation content courses and supervised laboratory experience

Abstract

In a sample of 74 university students studying early childhood and pre‐kindergarten education, researchers assessed the relationships between child development knowledge, complexity of reasoning about development, prior work experience with children, and teacher‐preparation content courses and laboratory courses. There was no statistically significant association between knowledge of child development and complexity of reasoning. The former primarily involves the acquisition of facts about patterns of general change, whereas complexity of reasoning permits caregivers to apply those facts to real‐life care‐giving dilemmas. Child development knowledge was predicted by the number of completed pre‐kindergarten content courses, but not by experience with children. Complexity of reasoning was predicted by both content and laboratory courses, the effects of which were assessed separately. Findings suggest that teacher‐preparation content courses, supplemented by guided experience with children, provide a basic framework for integrating important concepts about children's growth and behavior.     

“Why do dogs pant?”: Characteristics of parental explanations about science predict children's knowledge

Using a new method for examining parental explanations in a laboratory setting, the prompted explanation task, this study examines how characteristics of parental explanations about biology relate to children's knowledge. Parents (N = 148; M_age = 38; 84% female, 16% male; 67% having completed college) of children ages 7–10 (M_age = 8.92; 47% female, 53% male; 58% White, 9.5% Black, 9.5% Asian) provided answers to eight how and why questions about biology. Parents used a number of different approaches to address the questions, including providing more mechanistic responses to how questions and more teleological responses to why questions. The characteristics of parental explanations—most notably, how frequently parents provided correct responses—predicted children's performance on measures of verbal intelligence and biological knowledge. Additional exploratory analyses and implications for children's learning are discussed.     

Effective behavior management in preschool classrooms and children's task orientation: Enhancing emergent literacy and language development

This study investigated the relations among preschool teachers’ behavior management, children's task orientation, and children's emergent literacy and language development, as well as the extent to which task orientation moderated the relation between teachers’ behavior management and children's emergent literacy and language development. Participants included 398 children and 67 preschool teachers from preschool programs serving an at-risk population. Teachers’ behavior management was observationally assessed and children's task orientation was measured via teacher-report. Children's language and emergent literacy skills were directly assessed in the fall and in the spring of the preschool year. Hierarchical linear models were used to predict children's residualized gain in emergent literacy and language (i.e., Spring scores with Fall scores as covariates) from their task orientation and their teachers’ behavior management. Task orientation and behavior management each positively predicted children's emergent literacy development, but not language development. There was a significant interaction between teachers’ behavior management and children's task orientation in predicting children's language development, such that high scores on both variables were associated with the most optimal language outcomes. Implications for research and early education are discussed.     

Grasping the essence of a science activity by using a model of pedagogical reasoning and action

This article grasps the essence of how a science content can be foregrounded by elaborating around concepts as floating and sinking, in relation to boats. The data consist of a videotaped authentic session with one preschool teacher and four children. The model of pedagogical reason and action [Shulman, L. S. 1987. “Knowing and Teaching: Foundations of the New Reform.” Harvard Educational Review 57 (1): 1–23. doi:10.17763/haer.57.1.j463w79r5645541] constitutes the analytical lens. The results show that the content is framed within a series of creative activities where children’s suggestions of how to act are crucial. The scientific content is approached according to the children’s verbalisations of their understandings. Furthermore, dialectical relationships become the main tool when making the content visible.     

Young Children's Self‐Concepts Include Representations of Abstract Traits and the Global Self

There is debate about the abstractness of young children's self‐concepts—specifically, whether they include representations of (a) general traits and abilities and (b) the global self. Four studies (N = 176 children aged 4–7) suggested these representations are indeed part of early self‐concepts. Studies 1 and 2 reexamined prior evidence that young children cannot represent traits and abilities. The results suggested that children's seemingly immature judgments in previous studies were due to peculiarities of the task context not the inadequacy of children's self‐concepts. Similarly, Studies 3 and 4 revealed that, contrary to claims of immaturity in reasoning about the global self, young children update their global self‐evaluations in flexible, context‐sensitive ways. This evidence suggests continuity in the structure of self‐concepts across childhood.     

A Review of Children's,Teachers' and Parents' Influences on Children's Drawing Experience

In this article we argue that research into children's drawings should consider the context in which drawing occurs and that it is crucial to investigate the attitudes and practices of teachers, parents and children themselves that shape children's drawing experience and the drawings which they produce. We review the findings of seven empirical studies reporting data collected through direct observations, interviews and questionnaires from the three main players (teachers, parents and children) on the attitudes and practices shaping children's drawing. Issues covered include teachers' perceptions of the purposes and importance of drawing, support offered by teachers, parents and children for children's drawing endeavours, and possible factors that may lead to an age‐related decline in the amount of drawing children choose to do. We end the review by reporting some preliminary findings from our own large‐scale interview and survey study of 270 5–14 year old children, their parents and teachers, that provides a comprehensive assessment of attitudes and practices influencing children's drawing experience at home and at school. The findings provide further insight into the aforementioned issues, particularly children's, teachers' and parent's explanations of why children's drawing behaviour might decline with age. It is hoped that by reporting these preliminary findings some additional understanding of the context in which children produce their drawings can be gained and new areas for debate opened up.
