Research Findings: Evolution by natural selection is often relegated to the high school curriculum on the assumption that younger students cannot grasp its complexity. We sought to test that assumption by teaching children ages 4–12 (n = 96) a selection-based explanation for biological adaptation and comparing their success to that of adults (n = 30). Participants provided explanations before and after a 10-min, analogy-based tutorial illustrating the principles of variation, differential survival, differential reproduction, inheritance, and population change. Although younger children (ages 4–6) showed minimal evidence of learning these principles, older children (ages 7–12) showed robust evidence of doing so, learning them at rates equivalent to adults. Participants of all ages, however, provided nonevolutionary explanations for biological adaptations (i.e., explanations referencing need, growth, and creation) nearly as often at posttest as they did at pretest. Practice or Policy: These results suggest that older elementary school-age children can be taught evolutionary concepts but that learning such concepts does not lead to the automatic replacement of nonevolutionary views of biological adaptation, which must be addressed separately.  相似文献

Research Findings: In this research we explore the relationship between young children’s number knowledge and their measurement of length. First, we examined 4- to 5-year-olds’ (kindergartners’) understanding of and preference for using standard or nonstandard units to measure length. Second, we investigated whether the following tasks were related to children’s understanding of using standard (i.e., rulers) and nonstandard (i.e., blocks) units to measure length: (a) counting and written number identification knowledge, (b) symbolic or nonsymbolic number magnitude comparison ability, and (c) approximate number line estimation ability. Third, we examined whether understanding these number tasks predicted understanding how to measure length for both standard and nonstandard units. Our results show that young children prefer to use standard units of measurement when given a choice, and some of these children use a ruler correctly. Our results also show an important relationship between children’s understandings of numbers and measurement. Practice or Policy: Given children’s preference for rulers, introducing both nonstandard and standard units in early learning settings concurrently rather than consecutively is recommended for practice.  相似文献

In collaborative problem solving, children produce and evaluate arguments for proposals. We investigated whether 3- and 5-year-olds (N = 192) can produce and evaluate arguments against those arguments (i.e., counter-arguments). In Study 1, each child within a peer dyad was privately given a reason to prefer one over another solution to a task. One child, however, was given further information that would refute the reasoning of their partner. Five-year-olds, but not 3-year-olds, identified and produced valid and relevant counter-arguments. In Study 2, 3-year-olds were given discourse training (discourse that contrasted valid and invalid counter-arguments) and then given the same problem-solving tasks. After training, 3-year-olds could also identify and produce valid and relevant counter-arguments. Thus, participating in discourse about reasons facilitates children’s counter-argumentation.  相似文献

Despite the general effectiveness of multimedia instruction, students do not always benefit from it. This study examined whether students’ learning from multimedia can be improved by teaching them relevant learning strategies. On the basis of current theories and research on multimedia learning, the authors developed a strategy training for 9th-grade students. To evaluate it, 31 students received the aforementioned training and 33 students received placebo control training. After that, students completed a multimedia learning session on meiosis. Results showed that although the experimental training improved students’ strategy knowledge, it had no effect on learning outcomes. Accordingly, students acquired strategy knowledge but did not apply it later. Implications for the design of multimedia strategy interventions and future research are discussed.  相似文献

Abstract

Based on Fiedler’s contingency model of leadership, it was assumed that the teacher style required for effective student learning in the classroom depends on the favorableness of the situation for teaching (favorableness is defined in terms of ease of exercising influence). A person-oriented teacher was expected to be more effective than a task-oriented teacher in a situation of intermediate favorableness. A task-oriented teacher was expected to be more effective in an unfavorable situation. In support of these predictions, eighth-grade male students in a situation of intermediate favorableness rated the person-oriented teacher more positively than the task-oriented teacher in terms of effectiveness, encouragement, interest, and how much they learned. In an unfavorable situation, the opposite pattern occurred: students rated the task-oriented teacher more positively than the person-oriented teacher. Results on a performance test at the end of the lesson, though not significant, were in the predicted direction that paralleled the results on students' impression ratings. The implications of these results for teacher education were considered.  相似文献

Studies of the role of phonological representations in learning to read have almost exclusively focused on speech perception. In the current study, we examined links between sensorimotor control of speech, reading, and reading-related abilities. We studied two languages, English and Dutch, which vary in the regularity of their spelling-to-sound mappings. There were 236 American and Dutch children, 4 to 8 years old, who performed an altered auditory feedback task in which the first formant of the /?/ vowel was altered. A stronger response to altered feedback for literate relative to preliterate children was observed, and this was particularly the case for the Dutch children. Moreover, the magnitude of the responses was related to precursors of reading in preliterate children and to reading skill in literate children. We propose that these findings could be related to changes in children’s speech production skills that facilitate the integration of orthographic and phonemic information.  相似文献

Children live in a world where disagreement is commonplace. Although disagreement can sometimes be explained by differences in people’s reliability, disagreement may also indicate that the referent elicits multiple perspectives. The present studies (total N = 129, 5- to 12-year-old ethnically diverse U.S. children, 42% girls) examined children’s ability to resolve disagreement among two individuals by identifying referents that integrated the perspectives, and considered the extent to which any age-related change could be explained by epistemological understanding (i.e., acknowledging that two perspectives can be right). Children’s age was positively correlated with their ability to integrate perspectives, and children performed at above-chance levels by approximately 10 years of age. Age differences in integrating perspectives were partially accounted for by epistemological understanding.  相似文献

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.  相似文献

This study investigated the relationship between children’s ability to regulate emotions and display of appropriate behavior in social settings. A sample of 33 children representing a wide range of social economic status was randomly selected from a Head Start Program and an Early Childhood Development Center in the Midwest. Data were collected using the Emotion Regulation Checklist (ERC) developed by Shields and Cicchetti (Dev Psychol 33:906–916, 1997, J Clin child Psychol, 27:231–395, 1998). A “Behavior Recording” checklist was developed and used to record appropriate and inappropriate behavior observed during children social interactions. Teacher ratings identified children as generally high emotion regulators. Girls had generally higher scores than boys in emotion regulation ability. A high relationship (r = .76) was also found between emotion regulation and display of appropriate behavior. Results indicate the importance of emotions in relation to a child’s well being and academic achievement. Additionally, these findings suggest a need for parents and early childhood educators to teach children appropriate emotional behavior when confronted with situations that are in conflict with societal norms.  相似文献

By age 2, children are developing foundational language processing skills, such as quickly recognizing words and predicting words before they occur. How do these skills relate to children’s structural knowledge of vocabulary? Multiple aspects of language processing were simultaneously measured in a sample of 2-to-5-year-olds (N = 215): While older children were more fluent at recognizing words, at predicting words in a graded fashion, and at revising incorrect predictions, only revision was associated with concurrent vocabulary knowledge once age was accounted for. However, an exploratory longitudinal follow-up (N = 55) then found that word recognition and prediction skills were associated with rate of subsequent vocabulary development, but revision skills were not. We argue that prediction skills may facilitate language learning through enhancing processing speed.  相似文献

We examined the independent contributions of prosodic sensitivity and morphological awareness to word reading, text reading accuracy, and reading comprehension. We did so in a longitudinal study of English-speaking children (N = 70). At 5–7 years of age, children completed the metalinguistic measures along with control measures of phonological awareness and vocabulary. Children completed the reading measures 2 years later. Morphological awareness but not prosodic sensitivity made a significant independent contribution to word reading, text reading accuracy, and reading comprehension. The effects of morphological awareness on reading comprehension remained after controls for word reading. These results suggest that morphological awareness needs to be considered seriously in models of reading development and that prosodic sensitivity might have primarily indirect relations to reading outcomes.  相似文献

Based on the assumptions of the Taxonomy(4) and its definitions of the cognitive processes, it was hypothesized that the first four taxonomic levels are related to intelligence alone, but that performance on the upper two levels would require creative as well as intellectual abilities. The Lorge-Thorndike Intelligence Test, two creativity tests, and taxonomic tests were administered to 141 eleventh graders. Multivariate stepwise regression procedures were employed to determine the contributions of IQ and creativity to variation on the taxonomic tests. Results support the hypotheses. Implications are discussed in relation to Bloom’s model of mastery learning and the teaching for creativity.  相似文献

The last chapter of Vygotsky’s last book, Thinking and Speech, is a compressed argument about the construction of consciousness through the internalisation of language. This article comments on Vygotsky’s analysis of the ‘voyage into the interior’ undertaken by oral speech as it is internalised and abbreviated into ‘inner speech’, and then further concentrated as non-verbal thought. The article focuses on the part that literature and especially poetry play in Vygotsky’s argument in this chapter, and suggests that in exploring the condensed semantics of inner speech Vygotsky is implicitly describing how poets turn private thoughts into ‘symbols for others’. It concludes with a commentary on Vygotsky’s use of Mandelshtam’s poem ‘The Swallow’, from which he draws his epigraph.  相似文献

Research Findings: Children learn most of their vocabulary incidentally, by hearing words used in their environment. This study explored which kinds of presentations of words, without any direct instruction, yielded greater depth of target word knowledge. Changes in 56 kindergartners’ depth of knowledge for each of 23 novel target words (N = 1,288) based on presentation in 1 of 3 conditions (read-aloud, teacher conversation, or both read-aloud and conversation) were explored and compared to control words that were never presented. A 2-level, cross-classification analysis modeled the postintervention score for each word for each child. Children’s word meaning knowledge improved most when words were presented via combined conversations and read-alouds. Vocabulary gains for words presented via conversations differed across classrooms. Practice or Policy: Both teacher conversations and read-aloud presentations of target vocabulary should be used together. Professional development for teachers’ effective vocabulary conversations may be needed.  相似文献

This study focuses on children’s understanding of hazardous household items (HHI) and waste (HHW). Children from grades 4, 5 and 6 (n=173) participated in a questionnaire and interview research design. The results indicate that: (a) on a daily basis the children used HHI and disposed of HHW, (b) the children did not realize the danger of these items and their exposure to hazardous substances, (c) some children ignore consequent adverse health effects, (d) school‐based recycling and other environmental education programs can have a significant effect on children’s conceptions, and (e) even though children use and discard HHI, they can also present a strong external environmental locus of control orientation, considering that others, and not they themselves, should deal with the problem. The findings enrich the knowledge base on the topic, and can be used in the development of environmental education pedagogies aimed at reducing environmental and health risks associated with the use and disposal of hazardous items.  相似文献

This study was designed to investigate children’s abilities to count and make quantitative comparisons. In addition, this study utilized reasoning questions (i.e., how did you know?). Thirty-four preschoolers, mean age 4.5 years old, participated in the study. According to the results, 89 % of the children (n = 30) were able to do rote counting and 70 % (n = 24) were able to do rational counting. When children were asked how they knew how many objects were in a set, 30 responded that they used a counting strategy. Sixty-five percent of children (n = 22) answered “zero” when no block was given and 21 children answered “nothing” when they were asked what zero meant to them. About quantitative comparisons, 65 % of children (n = 22) answered correctly when they were asked more and less questions.  相似文献

This study investigated whether children learn from exploration and act as effective informants by providing informative demonstrations tailored to observers’ goals and competence. Children (4.0–6.9 years, N = 98) explored a causally ambiguous toy to discover its causal structure and then demonstrated the toy to a naive observer. Children provided more costly and informative evidence when the observer wanted to learn about the toy than observe its effects (Experiment 1) and when the observer was ordinary than exceptionally intelligent (Experiment 2). Relative to the evidence they generated during exploration, children produced fewer, less costly actions when the observer wanted or needed less evidence. Children understand the difference between acting-to-learn and acting-to-inform; after learning from exploration, they consider others’ goals and competence to provide “uninstructed instruction”.  相似文献

This paper describes the development, implementation and preliminary evaluation of the Reaching Educators and Children (REACH) program, a training and coaching intervention designed to increase the capacity of early childhood teachers to support children’s social and emotional development. We evaluated REACH with 139 teachers of toddler and preschool classrooms. Teacher attendance and survey results suggest that teachers were highly satisfied with the training and materials. Data from classroom observation scales conducted pre- and post-REACH implementation suggest significant improvements in the sensitivity of teachers’ interactions with children in the classroom, and increased teacher use of targeted social and emotional supports (such as teaching children to resolve conflicts). Further, data from observations of children’s classroom behavior suggest increases in children’s prosocial behaviors and small but significant decreases in verbal aggression. These findings provide preliminary evidence that the REACH program may be effective in building teachers’ capacity to support social–emotional development of young children, and point to the need for additional research.  相似文献

As the economy diversifies and stratifies, more mothers of young children experience job instability. To advance understanding of the implications of this trend, this study examines the role of job instability in maternal sensitivity, an important component of child development, during their children’s first 3 years of life. Structural equation models with longitudinal multimethod data from the NICHD Study of Early Child Care and Youth Development (n = 1,211; 1991–1994) revealed that mothers’ involuntary job loss, but not other job transitions, was negatively associated with sensitivity. This association was most pronounced among mothers with less education. Mediation analyses found that the association was explained by changes in family income and maternal depression, pointing to policy-relevant mechanisms for reducing inequalities among children.  相似文献
