Domain-specific knowledge and memory performance in children

Developmental studies assessing the impact of domain-specific knowledge on memory are discussed. In the first section of the review, different ways through which domain-specific knowledge relates to strategy use in memory tasks are briefly summarized. Empirical evidence indicating nonstrategic effects of the knowledge base are discussed next. In particular, findings based on the expert-novice paradigm are used to compare the knowledge structure and memory performance of experts and novices of different ages, and to explore how individual differences relate to the acquisition and use of domain-specific knowledge. The review shows that domain-specific knowledge permits children to process and remember domain-related information more efficiently, apply strategies more effectively, and integrate novel information more easily than domains for which they have less detailed knowledge. If the knowledge base is particularly rich, it exerts a greater influence than other sources of memory development (i.e., memory capacity, strategies, and metamemory) combined.     

Inhibitory control and visuospatial working memory contribute to 5-year-old children's use of quantitative inversion

This study examined the hypothesis that general cognitive resources moderated 5-year-old children's performance differences between the Concrete Identical and the Pure Quantity conditions on inversion problems (a + b – b) but not on standard problems (a + b – c). Study 1 (N = 104) showed that children who experienced higher visuospatial working memory burden performed significantly poorer in solving the inversion problems in the Pure Quantity condition than in the Concrete Identical condition, whereas those who experienced lower working memory burden showed no such difference. Study 2 (N = 194) demonstrated that children with lower levels of inhibitory control solved significantly fewer inversion problems in the Pure Quantity condition than in the Concrete Identical condition, whereas no such difference was found in children with higher levels of inhibitory control. These findings suggest that inhibitory control and visuospatial working memory may support children's use of quantitative inversion.     

The effects of documentation on young children's memory

A central aspect of the Reggio approach to early childhood education is documentation, in which educators observe, record, and display children's work. Educational anecdotes and developmental theory suggest that documentation may facilitate children's memory; the current study explored this possibility empirically. Sixty-three preschool/kindergarten children experienced a novel learning event. Two days later, children were reminded with either documentation or worksheets of event details and the factual information that had been presented, or they were not reminded. Three weeks later, children completed a memory interview that included episodic and semantic measures. Children in the documentation and worksheet conditions remembered more factual information than those in the no-reminder condition. Children in the documentation condition produced more on-topic speech than those in the worksheet condition during reminding and a subsequent learning session. Potential benefits of documentation for classroom performance are discussed.     

Is the ‘Idiot's Box’ raising idiocy? Early and middle childhood television watching and child cognitive outcome

There is widespread belief that exposure to television has harmful effects on children's cognitive development. Most studies that point to a negative correlation between hours of television watching and cognitive outcomes, fail to establish causality. Using the National Longitudinal Survey of Youth (NLSY) we study young children between 5 and 10 years of age during late 1990s and early 2000s. We find strong evidence of negative correlations between hours of television watched and cognitive test scores. However, once parent's characteristics and unobserved child characteristics are taken into account these correlations go away. We find that hours of television viewed per se do not have any measurable impact on children's test scores. Our results are robust to different model specifications and instrumental variable estimates. We conclude that despite the conventional wisdom and the ongoing populist movement, proactive policies to reduce children's television exposure are not likely to improve children's cognitive development and academic performance.     

MyTeachingPartner-Math/Science pre-kindergarten curricula and teacher supports: Associations with children's mathematics and science learning

MyTeachingPartner-Math/Science (MTP-MS) is a system of two curricula (math and science) plus teacher supports designed to improve the quality of instructional interactions in pre-kindergarten classrooms and to scaffold children's development in mathematics and science. The program includes year-long curricula in these domains, and a teacher support system (web-based supports and in-person workshops) designed to foster high-quality curricular implementation. This study examined the impacts of the intervention on the development of mathematics and science skills of 444 children during pre-kindergarten, via school-level random assignment to two intervention conditions (Basic: MTP-M/S mathematics and science curricula, and Plus: MTP-M/S mathematics and science curricula plus related teacher support system) and a Business-As-Usual control condition (BaU). There were intervention effects for children's knowledge and skills in geometry and measurement as well as number sense and place value: Children in Plus classrooms made greater gains in geometry and measurement, compared with those in BaU classrooms. Children in Plus classrooms also performed better on the number sense and place value assessment than did those in Basic or BaU classrooms. We describe the implications of these results for supporting the development of children's knowledge and skills in early childhood and for developing and providing teachers with professional development to support these outcomes.     

Audio-Visual aids in education - the beginning

The many achievements of the Educational Foundation for Visual Aids and the National Committee for Audio-Visual Aids to Education, under the leadership of the late Dr J A Harrison from their inception until his death last year, might lead many ‘Educational Media’ leaders to think that the audio-visual movement in Education was essentially a postwar development. That this is not so is evidenced by the fact that more classroom teaching films were being made in Britain n i each of the years 1934—39 than are being made today! There were annual conferences organised by the British Film Institute and the Educational Handwork Association; there were frequent articles on the subject and reviews of new films in Sight & Sound, World Film News, The Schoolmaster, The Times Educational Supplement, British Journal of Photography, even one on Schools' television etc, and several books had been published: ‘The Cinema in Education’ in 1925, ‘Report on Educational and Documentary Films’ by the British Association for the Advancement of Science, 1930; ‘The Film in National Life’ 1932; ‘The Film in the Classroom’ 1932; ‘The Cinema in School’ 1933; ‘The Film in the School’ 1935; etc.     

Children at work: The home workplace

Young children's early experiences with the adult work world have generally been ignored by researchers. Consequently, little research base exists for understanding children's conceptions of the adult work world. This study, part of a larger investigation of families who work at home for income rather than in separate workplaces, focuses on children's experiences with work in such families. Twenty-seven children ages 7 months to 18 years were observed or interviewed in the family work setting. Findings indicate that all the verbal children held concrete knowledge of their parents' work, as was evidenced by their ability to label jobs, describe procedures, and name tools. Furthermore, all the children were involved with their parents' work in a developmental progression: (1) playing and watching, (2) simple tasks, (3) regular assistance, paid or unpaid, (4) regular paid work. Their experiences suggest that home-working parents play a powerful role in their children's work socialization.     

Intrapersonal Emotion Regulation Processes Influence What Children Remember About Their Emotional Experiences

Little work has tested how emotion regulation (ER) processes influence children's memory for negative experiences. We investigated how two intrapersonal ER processes (affect-biased attention and changes in negative feelings) predicted children's (N = 184, 93 girls, ages 3–11) memory. Recall of a sad or scary film was tested after a delay. The way discrete emotional information was remembered varied with ER and children's age. Older children with greater affect-biased attention or less reduction of fear demonstrated privileged memory for central information from the scary film. Older children with greater affect-biased attention but greater reductions in sadness recalled more from the sad film overall. Findings suggest ER processes should be considered when examining children's memory for negative emotional information.     

Reading instruction affects the cognitive skills supporting early reading development

This study examined the cognitive skills associated with early reading development when children were taught by different types of instruction. Seventy-nine children (mean age at pre-test 4;10 (.22 S.D.) and post-test 5;03 (.21 S.D.)) were taught to read either by an eclectic approach which included sight-word learning, guessing from context and analytic phonics, or by a synthetic phonics approach, where children were taught solely to sound and blend letters to read unfamiliar words. The results illustrated differences in the skills supporting children's word reading based on their method of reading instruction. For the eclectic group, pre-test letter knowledge, vocabulary and rhyming skills predicted later reading ability, whereas for the synthetic phonics group, letter knowledge, phonemic awareness and memory span predicted later reading skill. The results suggest that children will draw upon different cognitive skills when reading if they are taught to use different word recognition strategies.     

Comfort drawing during investigative interviews: Evidence of the safety of a popular practice

Objective

This study evaluated the impact of comfort drawing (allowing children to draw during interviews) on the quality of children's eyewitness reports.

Methods

Children (N = 219, 5 to 12 years) who had participated in an earlier memory study returned 1 or 2 years later, experienced a new event, and described these events during phased, investigative-style interviews. Interviewers delivered the same prompts to children in the no drawing and drawing conditions but provided paper and markers in the drawing condition, invited these children to draw, and periodically asked if they would like to make another picture.

Results

Most children in the drawing condition were interested in using the materials, and measures of eyewitness performance were sensitive to differences in cognitive ability (i.e., age) and task difficulty (i.e., delay between the remote event and interview). Comfort drawing had no overall impact as evidenced by nonsignificant main effects of condition across 20 performance measures, although more of the younger children reported experienced touching in the drawing than no drawing condition.

Conclusions

The children successfully divided attention between voluntary drawing and conversations about past events. Importantly, comfort drawing did not impair the amount of information recalled, the accuracy of children's answers, or even the extent to which interviewers needed to prompt for answers. Due to the large number of analyses, the benefit of drawing for younger, touched children requires replication.

Practice Implications

Comfort drawing poses no documented risks for typically-developing school-aged children, but the practice remains untested for younger children and those with cognitive impairments.     

Fostering Parental Support for Children's Mathematical Development: An Intervention with Head Start Families

The first national education goal, school readiness, recognizes a need for young children to be better prepared for entry into elementary school. Many low-income children exhibit a pattern of underachievement in school mathematics. Research has revealed a developmental gap between low-income preschool children and their middle-class peers with respect to the extent of their numerical knowledge. Research has also found that many low-income children do not receive a broad base of support for mathematical development at home or in preschool. In each of two studies, we conducted a bi-generation (parent and child) mathematics intervention with Head Start families. The intervention was designed to enhance parental support for pre-kindergarten children's mathematical development. It was found that low-income parents were willing and able to support this area of their children's development once they were provided with the training to do so. The support that parents provided to their children through the intervention was clearly effective in enhancing the development of children's informal mathematical knowledge. Intervention children developed more extensive mathematical knowledge than a comparison group of low-income children. Thus, an important step toward achieving the school readiness goal can be taken by fostering low- income parents' support for young children's mathematical development.     

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.     

Fitting the Message to the Listener: Children Selectively Mention General and Specific Facts

In three experiments, two hundred and ninety‐seven 4‐ to 6‐year‐olds were asked to describe objects to a listener, and their answers were coded for the presence of general and specific facts. In Experiments 1 and 2, the listener's knowledge of the kinds of objects was manipulated. This affected references to specific facts at all ages, but only affected references to general facts in children aged 5 and older. In Experiment 3, children's goal in communicating was either pedagogical or not. Pedagogy influenced references to general information from age 4, but not references to specific information. These findings are informative about how children vary general and specific information in conversation, and suggest that listeners' knowledge and children's pedagogical goals influenced children's responses via different mechanisms.     

Learning From Others: The Effects of Agency on Event Memory in Young Children

Little is known about the influence of social context on children's event memory. Across four studies, we examined whether learning that could occur in the absence of a person was more robust when a person was present. Three-year-old children (N = 125) viewed sequential events that either included or excluded an acting agent. In Experiment 1, children who viewed an agent recalled more than children who did not. Experiments 2a and 2b utilized an eye tracker to demonstrate this effect was not due to differences in attention. Experiment 3 used a combined behavioral and event-related potential paradigm to show that condition effects were present in memory-related components. These converging results indicate a particular role for social knowledge in supporting memory for events.     

The relationship between early childhood teachers' instructional quality and children's mathematics development

This study examined how early childhood (EC) teachers' instructional quality predicted children's development in mathematics across two measurement occasions. Therefore, EC teachers' (n = 25) instructional quality was assessed using one standardized observation instrument covering both domain-specific and general aspects of instructional quality. Additionally, data on children's (n = 208) outcome in early number skills was collected applying a standardized test. Multilevel structural equation modeling was used accounting for nested data. Children's age and the average size of preschool groups were controlled for. Results revealed that EC teachers' instructional quality predicted children's development but was not associated with their initial achievement. The findings suggest that instruments covering domain-specific and general aspects might be helpful in order to measure EC teachers' instructional quality in mathematics and predict children's learning growth. Understanding the mechanisms between instructional quality and children's development may help EC teachers to enhance their math teaching in practice.     

Does intensity matter? Preschoolers’ print knowledge development within a classroom-based intervention

The present study examined the extent to which two dimensions of intervention intensity, (dose frequency and dose) of a 30-week print-referencing intervention related to the print knowledge development of 367 randomly selected children from 55 preschool classrooms. Dose frequency refers to the number of intervention sessions implemented per week; teachers were randomly assigned to either the high-dose frequency condition (four intervention sessions per week) or the low-dose frequency condition (two intervention sessions per week). Dose refers to number of print-referencing teaching strategies used per intervention session and was a naturally varying variable across classrooms. Structural models of children's spring print knowledge showed a significant interaction of dose and dose frequency in relation to children's outcomes. Follow-up analyses showed that the benefit of providing four versus two print-referencing sessions per week disappeared when teachers were providing a relatively intense number teaching strategies within sessions (i.e., the dose was high). Considered differently, findings also show that increasing the number of print referencing teaching strategies within a session (i.e., the dose) related positively to children's print knowledge development, but only when the weekly number of intervention sessions were low (i.e., two intervention sessions weekly). Overall, findings show that there is a benefit to increasing the dose or dose frequency of the print referencing intervention, but increasing both aspects of intervention intensity appeared to have a diminishing benefit to children's learning. Findings empirically support the multi-dimensional nature of intervention intensity and implications for research and practice are discussed.

Learning while playing: Children's Forest School experiences in the UK

Children's outdoor play is declining, despite clear links between play, learning and development. Alternative learning initiatives which provide children with a diversity of play opportunities, including the chance to play outdoors, are therefore needed. One such programme, Forest School, is increasing in popularity in the UK and internationally, yet little is understood about its impact on children's learning, or how alternative approaches are informing learning in mainstream settings. This novel study examined primary school children's experiences of engaging in a Forest School programme in relation to this intersection between formal and informal approaches to learning. It explored how children interpret their experiences when faced with a fusion of learning environments and critically evaluates the benefits children realise, when asked to reflect on their learning engagement in both classroom and outdoor settings. Interviews were conducted with 33 children from two mainstream primary schools in England who had recently completed a 6-week Forest School programme. A rigorous phenomenological thematic analysis revealed three inter-related themes: a break from routine; learning through play; collaboration and teamwork. The findings suggest that the blending of Forest School with mainstream settings contributes to children's social, cognitive, emotional and physical skill development through experiential learning using play. These findings are significant because they not only emphasise the values of social constructivist play-pedagogy which underpin Forest School practice, but also highlight the need for primary schools to consider learning outside of the classroom as an effective pedagogy.     

Individual variation in children's reading comprehension across digital text types

The present study examined children's digital text comprehension of digital text types linear digital text vs hypertext, with or without graphical navigable overviews. We investigated to what extent individual variation in children's comprehension could be explained by lexical quality (word reading efficiency and vocabulary knowledge), cognitive load factors (prior knowledge and working memory), text type and graphical overview. Participants were 93 sixth graders in a within‐subject design. Word reading efficiency, vocabulary knowledge and prior knowledge predicted children's digital comprehension scores, while working memory did not. Reading comprehension was equal for linear text or hypertext. However, the presence of an overview facilitated reading comprehension for readers with lower prior knowledge. It can be concluded that hypertexts with basic digital text features and accompanying comprehension questions are not more difficult for children than linear digital texts, that similar individual factors predict reading comprehension of linear text and hypertext, and that a graphical overview helps when prior knowledge is low.
