Misconceptions about adaptation by natural selection are widespread among adults and likely stem, in part, from cognitive biases and intuitive theories observable in early childhood. Current educational guidelines that recommend delaying comprehensive instruction on the topic of adaptation until adolescence, therefore, raise concerns because children's scientifically inaccurate theories about species may be left unchallenged for many years, allowing them to entrench and become difficult to overcome. In consequence, this investigation sought to explore whether classrooms of kindergartners and second graders could acquire a basic but comprehensive understanding of adaptation from an intervention constructed around two picture storybooks that mechanistically explain natural selection. Learning was assessed in near and far transfer contexts both immediately and a month later. Kindergartners and second graders demonstrated substantial learning of biological information; however, second graders showed pronounced abilities to near and far generalize, immediately and over time. Results suggest that causally cohesive interventions with an emphasis on mechanistic explanation facilitate children's classroom learning of complex counterintuitive scientific ideas.  相似文献

This study examined the impact of direct instruction and interactive instruction on immigrant kindergarten children’s vocabulary learning during storybook reading. (In the present study the terms “immigrants” and “second language learners” are used alternatively meaning kindergarteners from immigrant families who are in the process of acquiring a second language besides their mother tongue.) Eighty seven immigrant kindergarten children, aged 4–6 years old (mean = 61.68 months, standard deviations = .51) were recruited from 12 public kindergarten classrooms located in Crete. Children were acquiring Greek as a second language. The immigrant children of the 12 kindergarten classrooms were randomly assigned to two experimental groups and one control group. During the intervention phase, six stories were read twice in whole group settings. Target and non-target words were assessed by multiple choice vocabulary measure before and after the storybook readings. In the first experimental group, children were provided brief explanations of target words by direct instruction. In the second experimental group, children were involved actively in discussing target words according to interactive instruction techniques. In the control group stories were read without any explanation of target vocabulary. Results showed that interactive instruction was more beneficial on target vocabulary learning than direct instruction and the impact was greater for instructed words than for uninstructed ones. In addition, results showed that boys and girls responded differently to the teaching procedures. Specifically, in both conditions where teaching procedures were implemented, girls outperformed boys on instructed words. Furthermore, children’s initial level in Greek receptive vocabulary and target word knowledge had a significant impact on target word learning.  相似文献

The home literacy environment is a well-established predictor of children’s language and literacy development. We investigated whether formal, informal, and indirect measures of the home literacy environment predict children’s reading and language skills once maternal language abilities are taken into account. Data come from a longitudinal study of children at high risk of dyslexia (N = 251) followed from preschool years. Latent factors describing maternal language were significant predictors of storybook exposure but not of direct literacy instruction. Maternal language and phonological skills respectively predicted children’s language and reading/spelling skills. However, after accounting for variations in maternal language, storybook exposure was not a significant predictor of children’s outcomes. In contrast, direct literacy instruction remained a predictor of children’s reading/spelling skills. We argue that the relationship between early informal home literacy activities and children’s language and reading skills is largely accounted for by maternal skills and may reflect genetic influences.  相似文献

We investigated effects of listening to single or multiple storybook readings versus testing with and without feedback on children’s breadth (i.e., the number of words) and depth (i.e., the quality of word knowledge) of vocabulary learning. Kindergartners (n = 125) were divided into 3 intervention and 1 control conditions. Children in the control condition listened once to a storybook reading. In the experimental conditions, the initial storybook reading was followed by (a) repeated storybook reading, (b) repeated testing, or (c) repeated testing with feedback. For breadth of vocabulary, all 3 conditions showed learning gains compared to a single storybook reading, and no “testing effect” was found. For depth of vocabulary, repeated storybook reading and repeated testing with feedback were more effective than the control condition with the former seemingly most effective. Both for breadth and depth of vocabulary, the effects of testing were found to be conditional upon the provision of feedback.  相似文献

Research Findings: In order to identify the active ingredients in an effective professional development intervention focused on enhancing preschool vocabulary instruction, this study examines the frequency with which teachers and children discussed theme-related vocabulary words during shared book reading. Head Start teachers received 1 year of training focused upon early vocabulary development. Children's vocabulary skills were assessed in the fall and spring of the school year. In spring, teachers read a storybook to their classroom, and teachers’ and children's remarks about theme-related vocabulary during the reading—including contextualized and decontextualized statements as well as verbatim repetitions of one another's statements—were coded. Practice or Policy: Results of multilevel models showed that more frequent references to thematic vocabulary by teachers were linked to stronger child vocabulary development. Although children's vocabulary references were not uniquely predictive of vocabulary learning, teachers’ repetition of children's remarks contributed to children's vocabulary gains.  相似文献

This article explores the preschool teachers’ use of concrete and abstract comments and questions within the classroom contexts of storybook reading and guided play to promote classroom conversations. Early childhood educators promote oral language development by creating a language-rich environment in which children become active participants in classroom dialogue. Teachers must intentionally plan and scaffold this learning through interactive storybook reading and storybook extensions using props through guided play. This article provides examples of the types of comments and questions that can serve to model and facilitate children’s vocabulary and comprehensive language development and subsequent literacy skills.  相似文献

This study assessed the effects of three different intervention programs on low-SES mother?Cchild joint activities and on their kindergarten-age children??s progress in early literacy and language. Parents in three groups (119 mothers, 5 fathers) were coached to mediate child learning, respectively, in: interactive storybook reading, writing, or visuomotor skills. A group-specific workshop was followed by 7?weeks of tri-weekly structured dyadic interactions and weekly tutorial home visits. A fourth group (control) received no intervention. Results showed implementation success: Mothers coached in interactive storybook reading or writing mediation improved in the coached activity from pretest to immediate posttest and to delayed posttest. Interactive storybook reading improved less for older than younger children, whereas writing mediation improved more for older than younger children. No transfer emerged from one activity to the other: Coaching on reading had no effect on writing or visuomotor skills, and coaching of writing had an effect only on writing. Children??s alphabetic skills were enhanced in the writing mediation-coached group, whereas linguistic competencies, unexpectedly, were not enhanced in the interactive storybook reading-coached group. The significance of writing mediation as a dyadic activity promoting literacy is emphasized.  相似文献

The study examined the differential contributions on vocabulary and alphabetic skills of three literacy programs: (a) storybook reading program; (b) alphabetic skills program; and (c) a combined program. It was expected that storybook reading would enhance primarily vocabulary while alphabetic skills training would promote primarily alphabetic skills. Program by age interactions were examined in two age groups (3–4 and 4–5 years old) to test whether the storybook reading program may be more productive for the younger children whereas alphabetic skills program more productive for the older children. Twelve low-SES preschools participated in the study, three in each program and three as a comparison group. Results indicated that the children in the three intervention programs progressed significantly more than the comparison group on name writing, letter knowledge and phonological awareness. Further, the alphabetic skills program outperformed the other groups on word writing, letter knowledge and initial letter retrieval, whereas the storybook reading program outperformed only the comparison group. Results on the combined program were mixed – enhancing more initial letter retrieval and book vocabulary than storybook reading program. In general, no differences emerged in the progress of younger versus older children except on receptive vocabulary – the younger surpassing the older in all programs.  相似文献

This study compared levels of parent involvement in early intervention services for children under three which were delivered in community settings (children’s homes and child care programs) and specialized settings (early intervention centers and provider offices) in the USA. Respondents reported the highest levels of parental involvement in the home. However, level of involvement in the home was not significantly higher than the provider’s office for parent attendance, quality and content of parent-provider communication, and effective instruction; level of provider communication and instruction to parents was not significantly higher in the home than in the early intervention center. Early intervention services in the child care setting were associated with the lowest levels of parent involvement. With the exception of child care, these results suggest that specialized and natural settings are associated with similar levels of parent involvement.  相似文献

A randomized controlled trial was conducted to determine the efficacy of U-Pace instruction for older undergraduates, ages 25 and older, and younger undergraduates, ages 18 to 24. Additionally, change in learner perceptions across the semester, an outcome not reported in the literature on U-Pace instruction, was investigated. In both younger and older undergraduates U-Pace instruction produced greater learning, greater academic success, and sustained or improved students’ perceptions of themselves as learners compared with Face-to-Face instruction. The findings provide strong support for the efficacy of U-Pace instruction in younger and older students and highlight a possible mechanism underlying U-Pace instruction’s effects on learning and academic success.  相似文献

Literacy instruction is a powerful determinant of children’s academic and school outcomes. Teachers’ training for literacy instruction is therefore critical for children’s reading learning. The present study examined the contents of 130 courses related to literacy instruction from a representative national sample of primary teachers’ undergraduate programs (N = 81), to address the following issues: which courses, related to literacy instruction, are included in the curriculum of undergraduate training programs? Which is the weight of the courses in undergraduate programs? What are the contents of the courses? The results show that most critical features of literacy instruction are included in the course contents of most programs (e.g. phonics, theory of literature). Still, some other critical features are underrepresented (reading/writing comprehension skills) or apparently missing (assessment and intervention in reading/writing problems). Moreover, the time allocated to literacy instruction seems to be scarce. Still, wide differences across university programs and courses were found.  相似文献

Children’s experiences with early numeracy and literacy activities are a likely source of individual differences in their preparation for academic learning in school. What factors predict differences in children’s experiences? We hypothesised that relations between parents’ practices and children’s numeracy skills would mediate the relations between numeracy skills and parents’ education, attitudes and expectations. Parents of Greek (N = 100) and Canadian (N = 104) five‐year‐old children completed a survey about parents’ home practices, academic expectations and attitudes; their children were tested on two numeracy measures (i.e., KeyMath‐Revised Numeration and next number generation). Greek parents reported numeracy and literacy activities less frequently than Canadian parents; however, the frequency of home numeracy activities that involved direct experiences with numbers or mathematical content (e.g., learning simple sums, mental math) was related to children’s numeracy skills in both countries. For Greek children, home literacy experiences (i.e., storybook exposure) also predicted numeracy outcomes. The mediation model was supported for Greek children, but for Canadian children, the parent factors had both direct and mediated relations with home practices.  相似文献

Research Findings: The present study compared effects of explicit instruction on and practice with the phonological form of words (form-focused instruction) versus explicit instruction on and practice with the meaning of words (meaning-focused instruction). Instruction was given via interactive storybook reading in the kindergarten classroom of children learning Dutch. We asked whether the 2 types of instruction had different effects on vocabulary development and 2 precursors of reading ability—phonological awareness and letter knowledge—and we examined effects on these measures of the ability to learn new words with minimal acoustic-phonetic differences. Learners showed similar receptive target-word vocabulary gain after both types of instruction, but learners who received form-focused vocabulary instruction showed more gain in semantic knowledge of target vocabulary, phonological awareness, and letter knowledge than learners who received meaning-focused vocabulary instruction. Level of ability to learn pairs of words with minimal acoustic-phonetic differences predicted gain in semantic knowledge of target vocabulary and in letter knowledge in the form-focused instruction group only. Practice or Policy: A focus on the form of words during instruction appears to have benefits for young children learning vocabulary.  相似文献

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

Several researchers have shown that children’s ability to make inferences is related to their reading comprehension. The majority of research on this topic has been conducted on older children. However, given the recent focus on the importance of narrative comprehension in prereaders, the current study examined the relationship between inference making and story comprehension in 4- to 5-year-olds. We examined children’s online inferences while narrating a wordless book as well as children’s story comprehension of a different storybook. We found that children’s total number of inferences was significantly related to their story comprehension. Three types of inferences were significantly related to story comprehension—characters goals, actions that achieved those goals, and character states. In a hierarchical regression controlling for children’s age and expressive vocabulary, a composite of these three inference types significantly predicted children’s story comprehension.  相似文献

Research Findings: In the United States a shift has occurred in how children are identified for long-term special education services. Since 2004, U.S. funding for special education services has included a provision for early intervention services, focusing on the importance of providing supplemental instructional opportunities to students who are not successful in learning from the core classroom instruction. Commonly referred to as response to intervention, this model involves educators monitoring how well students respond to intervention instruction, with referral for special education services for those who make little progress. Practice or Policy: In this article, we propose that intervention instruction should be responsive to the learner as well as focus on how well the learner responds to the intervention. Given that contextual circumstances, including instructional experiences, impact the child's literacy achievement, providing intervention instruction that is contingent upon each child's literacy strengths and needs is the best way to ensure each child's successful response to intervention instruction. As an example of an intervention using responsive instruction, this article describes different instructional approaches provided by Reading Recovery teachers with 3 children who were initially the lowest readers and writers in their classes. All 3 children were able to progress to on-grade-level reading and writing proficiency as a result of the intervention.  相似文献

Effectiveness of a video self-modelling (VSM) intervention was examined with primary schoolchildren who attended a full-time special education programme for pupils with social emotional and behavioural difficulties and who exhibited inappropriate behaviour during small-group reading instruction. A randomised multiple-probe baseline design was used in this study in four subjects with a follow-up phase 6 weeks after intervention. Four children aged 10 were videotaped during reading instruction to determine levels of active learning and behavioural difficulties. Intervention took place at the teacher’s desk or table 3–5 minutes immediately before the child’s designated time for reading group instruction. During intervention, the children were shown carefully selected brief segments of their own video that had been recorded during the previous session. Results indicated VSM was an effective intervention for increasing active learning responses and for reducing behavioural difficulties during reading instruction. Optimum results were maintained for more than 8 weeks after intervention. These results support VSM as an effective antecedent intervention and add to the growing body of evidence-based practices for elementary school pupils who have social emotional and mental health difficulties.  相似文献

In two experiments we examined how children's nonword pronunciations are influenced by learning words. In Experiment 1, children pronounced nonwords before and after learning words sharing orthographic rimes with the nonwords. These rimes varied in spelling-to-sound consistency and regularity. Children's nonword pronunciations were more sensitive to consistency and regularity after instruction than before. Experiment 2 expanded upon Experiment 1 by modifying the instruction to highlight regularity and consistency in rime unit neighborhoods and by including both younger (M age = 7.6) and older (M age = 9.92) participants. After instruction, Experiment 2 participants demonstrated greater sensitivity to rime unit consistency and regularity than Experiment 1 participants. In both experiments, the children, especially the younger participants, made more adultlike pronunciations after instruction than before. We conclude that learning words varying in consistency and regularity increased the children's sensitivity to these properties.  相似文献

Background: While there is a considerable body of research exploring the relationship between older primary school children’s reading attitudes, confidence and attainment, there is a noticeable lack of research with younger children. Furthermore, there is relatively little research exploring the extent to which children’s reading attitudes, confidence and attainment are related to their enjoyment of learning to read.

Purpose: To understand the relationship between young children’s reading attitudes, reading confidence, enjoyment of learning to read and reading attainment.

Sample: Two hundred and three children (103 boys) with an average age of 6 years and 9 months (.32 years standard deviation) participated in this study. Children were from 11 primary schools in England, located within a wide range of socio-economic neighbourhoods.

Design and methods: All children completed questionnaires examining their attitudes to reading, reading confidence (using Progress in International Reading Literacy Study items) and enjoyment of learning to read. Children also completed an assessment of word reading. All assessments were administered individually.

Results: Children’s attitudes to reading, reading confidence and enjoyment of learning to read correlated with their word reading skill; however, only reading attitudes and reading confidence predicted variance in reading success. With regard to gender differences, girls reported more positive reading attitudes than boys, even after controlling for differences in reading skill.

Conclusions: Results highlight that the relationship between children’s reading skills and the affective aspects of learning to read develops from a young age. Therefore, methods of reading instruction need to foster affective aspects of reading, in addition to developing cognitive skills to best support young children’s reading development.  相似文献

Evidence-based practice is highly appreciated and demanded in the field of education, especially in relation to extra support provided for children struggling with learning. Currently, there is a lack of intervention studies in the area of mathematics. This study aimed to investigate the effects of a short mathematics intervention programme on second graders (Mage?=?8?years, 2?months) with low performance in mathematics, in a quasi-experimental, intervention-control setting. A group of low-performing second graders (LOWi, n?=?11) was taught twice a week for eight weeks on the mathematics topics of number word sequence skills, counting skills and conceptual place value knowledge. The intervention’s effectiveness was examined by comparing the mathematics performance of the LOWi group to those of two groups consisting of low performing (LOWc, n?=?13) and typically performing children (TYPc, n?=?64), who followed their business-as-usual mathematics instruction. The LOWi group made significant improvements in mathematics but did not show significantly better gains, compared to the LOWc and TYPc groups, immediately and three months after the intervention. We discuss the implications for educational practice and intervention research.  相似文献
