Student understandings of acids and bases: A two year study

Conclusion This study had indicated that further research needs to be done into the examination of how subsequent learning will interact with knowledge previously gained. Does the learning of new knowledge in relation to previously understood knowledge cause interference (Biggs & Telfer 1986) or does it result in some confusion culminating in lack of linkages (Osborne & Freyberg, 1985)? Can the benefits of constructivism be built upon when using other strategies? These are some of the questions which arise from the results obtained in this study. This study does not provide any definitive solution to the questions; however it does show that long term retention of concepts learnt using a constructivist strategy does occur.     

When victims don't cry: children's understandings of victimization, compliance, and subversion

How do children understand situations in which the targets of moral transgressions do not complain about the way they are treated? One-hundred and twenty participants aged 5, 7, 10, 13, and 16 years were interviewed about hypothetical situations in which one child ("transgressor") made an apparently unfair demand of another child ("victim"), who then responded by either resisting, complying, or subverting. In general, 5-year-olds judged compliance positively and resistance negatively and 7- to 16-year-olds judged resistance positively and compliance negatively; all but 16-year-olds judged subversion negatively. Most participants judged the transgressor's actions negatively, regardless of how the victim had responded. The findings are discussed in terms of their implications for children's developing understandings of victimization.     

Longitudinal study of young children's responses to challenging achievement situations

Three studies were conducted to replicate and extend Dweck's findings regarding young children's responses to challenging achievement situations. Dweck's dichotomous helplessness classification system (i.e., task choice, task choice reason) was replicated with kindergartners, n = 235 (50% male), and first graders, n = 70 (46% male). To test whether individual differences in young children's responses to challenging situations are stable over time, 1- and 5-year follow-ups of the kindergartners were conducted. On the basis of children's responses on age-appropriate behavioral tasks, a composite of cognitive, behavioral, and affective helplessness indices predicted helplessness at 1 and 5 years later, n = 114 (50% male), above and beyond kindergarten task ability and gender, p<.05. Kindergarten helplessness predicted teacher ratings of children's helplessness 5 years later as well, p<.05. The implications of these findings for early intervention are discussed.     

How can we find out what 3 and 4 year olds think? New approaches to eliciting very young children's understandings in science

This paper outlines work in progress on a study which is investigating what children understand about natural and processed materials and how scientific learning on the topic could be extended and reinforced in the home. Four different interview schedules for eliciting children's understanding were developed and tried out. Children's understandings prior to each of the four units, and at the conclusion of the teaching program were documented through individual interviews. Family interviews were also conducted prior to and at the conclusion to the teaching. In this paper the difficulties associated with researching young children's thinking are explored. The rationale for a storytelling context for the interviews is presented, and there is a preliminary discussion on the effectiveness of the methodology utilised.

Phantoms and fabrications:young children's detection of implausible lies

The present study investigated whether young children are gullible and readily deceived by another's lies. Specifically, this study examined whether young children believe a lie teller's statement when the statement violates their developing knowledge of a distinction between reality and fantasy. In the first three experiments 3- to 6-year-olds (N = 293) were presented with either a story or a live staged event in which an individual made an implausible statement about a misdeed (claiming that a ghost jumped out of a book and broke a glass). A significant age effect was obtained: 5- and 6-year-olds tended to report that the individual who made the implausible statement had actually committed the misdeed, whereas 3- and 4-year-olds tended to accept the claim of the protagonist. Experiment 4 revealed that 5- and 6-year-olds (N = 43) not only disbelieved an individual's implausible statement but also inferred that the individual was lying and had a deceptive intent. In contrast, Experiment 5 revealed that 3- and 4-year-olds (N = 41) had difficulty disbelieving an individual's implausible claim about an inanimate object (i.e., the claim that a chair came alive and broke the glass). The findings suggest that 5- and 6-year-olds are not so gullible as previously thought, and that they use their well-developed real-world knowledge to detect scapegoating lies. In contrast, many younger children tend to believe another's implausible lies, perhaps due to the fact that the knowledge needed to detect such lies has not yet been consolidated.     

Showing How Many: young children's written representation of number

Abstract This paper reports a simple experiment which explores young children's written representation of number. Previous research (e.g. Hughes, 1983; Sinclair, Siegrist & Sinclair, 1982) has shown that several factors may influence the extent to which children will spontaneously deploy their knowledge of numerals to represent numerosity, but the available evidence is insufficient to provide a clear account of the relative weight of these factors. The present experiment involved presenting five to six year‐old children with arrays of simple objects and manipulating the wording of the instructions. The results showed that the use of the term ‘how many’ led the vast majority of the children to show numerosity by using materials. In contrast, when asked to represent ‘what’ they could see, most children concerned themselves with depicting the nature of the objects in the array by drawing or writing. These findings suggest that the linguistic context of the task is important in determining the children's representational strategies. Furthermore, it is argued that children's understanding of number and their ability to use numerals is quite separable from their knowledge of when it is appropriate to deploy these skills.     

Dyslexia and learning musical notation: A pilot study

Both the alphabet and our system of musical notation are largely based on arbitrary conventions and associations. Conforming to the Dyslexic Automatization Deficit Hypothesis, children suffering from dyslexia are supposed to have difficulty in automating these types of conventions and/or associations. Scientific research into the relation between dyslexia and learning musical notation is rare. Therefore, we developed a new intervention paradigm on learning musical notation. This program was followed by five dyslexic children and four children without dyslexia, in order to study and compare the learning processes of both groups. The program consisted of instruction, practice in the skills and knowledge related to musical notation, and test assignments. During each session, the problem-solving process of the individual child was observed and the amount of time required to complete each assignment in the program was recorded. In addition we analyzed the errors made by the two groups of children in each session. A pretest-posttest comparison revealed that dyslexic children needed more time to learn musical notation than did children without dyslexia. Dyslexic children also made more mistakes and produced more ‘third transpositions’. The implications for teaching musical notation are outlined.     

A theoretical framework for studying educational media: A pilot study

Are different media equally effective for a given learning task when each presents the same event of instruction? Are given instructional materials equally effective for different types of learning outcomes? This pilot study used three types of stimulus materials—text, film, and live demonstration—to teach cardiopulmonary resuscitation to graduate students. Learning outcomes measured were verbal learning and a motor skill task.     

A study of the nature of students' understandings about the concept of burning

The purpose of this study was to identify and characterize students' understandings about the concept of burning. Naturalistic data-collecting strategies used in this study included participant observation and interviewing. Twenty eighth graders were interviewed using the “interview-about-events” technique, a variation of the Piagetian interview. The interviews were audiotape recorded, transcribed, and analyzed using the process of analytic induction. The analysis showed that students' understandings about burning were fragmented, inconsistent, and at variance with scientific knowledge. These understandings are analyzed using Olson's (1977) characterization of common sense and scientific knowledge.

Components of young children's trait understanding: behavior-to-trait inferences and trait-to-behavior predictions

Trait attribution is central to people's na?ve theories of people and their actions. Previous developmental research indicates that young children are poor at predicting behaviors from past trait-relevant behaviors. We propose that the cognitive process of behavior-to-behavior predictions consists of two component processes: (1) behavior-to-trait inferences and (2) trait-to-behavior predictions. Experiment 1 demonstrates that 4-, 5-, 7-, and 9-year-olds can infer trait labels from behaviors. Experiment 2 demonstrates that 4-, 5-, and 7-year-olds can predict behaviors from trait labels but not from past behaviors. Experiment 3 demonstrates that 4- and 5-year-olds understand traits as predictive and stable over time. Taken together, these three studies show that young children, in possessing component trait-reasoning processes, have a nascent understanding of traits.

Engaging young students in scientific investigations: prompting for meaningful reflection

This study examined the verbal prompts a tutor used to promote reflection and young students’ responses to these prompts. Seven children (ages 8–12) participated in 260 min of one-on-one tutoring to learn scientific concepts related to gear movement; the tutor spontaneously provided these students with 763 prompts for reflection. Prompts reliably induced reflection: Students responded verbally 87% of the time. Turn-by-turn discourse analysis revealed seven distinct types of prompts and 11 distinct types of verbal responses. High-level prompts were strongly associated with high-level responses. A log-multiplicative association model with two dimensions (temporality and certainty) represented the relationships between prompt and response types; from this model, odds ratios estimated the strength of association between specific pairs of prompt and response types. Findings are discussed in terms of the effects that reflection may have on students’ developing understanding of scientific concepts.     

A framework for designing interactive multimedia to scaffold young children's understanding of historical chronology

Young children's understanding of thehistorical past is often characterised by alack of temporal differentiation and a sense oftotal discontinuity with the present. Researchhas suggested that this situation may be causedin part by their formation of inappropriaterepresentations when solving problems ofchronology. To help children construct moreappropriate external representations forparticular tasks and reason more effectivelywith them about chronological concepts, weinvestigated the role that interactivemultimedia might play in scaffoldingteacher-led activities in the classroom. Inthis paper we report on our conceptual designand pedagogical approach to developingeffective dynamic, interactive representationsand activities at the computer interface, aimedat bridging the conceptual gap between concreteexperience and abstract concepts. Evaluationsof the software built using this frameworkshowed that the program was well received bychildren and teachers alike, and that it wasable to facilitate children's understanding of,and ability to reason about, chronology.     

Making Meaningful Choices: an investigation into young children's intonation patterns in storytelling

Abstract This paper investigates the meaningful choices in intonation made by young children. A category system for classifying choices is outlined and an experiment is reported in which randomly selected groups of 41/2‐5 year‐olds heard and retold stories in different situations. Results indicate that all groups distinguished narrative from other forms of discourse and drew upon intonation resources appropriately. Differences were found between recalling a story with pictures and one without, suggesting that these are different cognitive tasks and that children make different selections from choices available to them.     

Fathers' involvement in young children's literacy development: Implications for family literacy programmes

Relatively few studies of family literacy programmes have investigated parents' experiences and whilst a number of such programmes have been specifically aimed at fathers, little is known about the involvement of fathers in programmes which target both mothers and fathers. This article reports fathers' involvement in a family literacy programme and their home literacy practices with their young children. The article provides a definition of family literacy and describes the context of the study, which was carried out in socio‐economically disadvantaged communities in a northern English city. Fathers' participation in their children's literacy was investigated through interviews at the beginning and end of the programme (n = 85) and home visit records made by teachers throughout the programme. Quantitative and qualitative analysis of these data indicate that, while fathers' participation in the family literacy programme was not easily visible, almost all fathers were involved to some extent in home literacy events with their children. During the programme, teachers shared information about literacy activities and the importance of children having opportunities to share literacy activities with their parents. Data indicate that fathers who were not mentioned by mothers as having been involved in their children's literacy were significantly more likely to be on a low income than those who were reported as being engaged with their children in home literacy activities. Fathers in the study were involved in providing literacy opportunities, showing recognition of their children's achievements, interacting with their children around literacy and being a model of a literacy user. Although involved in all four of these key roles, fathers tended to be less involved in providing literacy opportunities than mothers. While fathers and sons engaged in what might be described as traditionally ‘masculine’ literacy activities, fathers were more often reported to be involved with their children in less obviously gendered home literacy activities. The article concludes with discussion of implications for involving fathers in future family literacy programmes.     

Learning How to Learn: Parental ethnotheories and young children's preparation for school

This paper discusses one aspect of the findings from an ethnographic study of the ways in which four-year-old children learn, and are taught, at home and in their Reception class. The children were from two distinctive cultural backgrounds within the same urban neighbourhood: one-half belonged to UK ('Anglo') families, and one-half to families from Bangladesh. They were observed and assessed throughout their first school year, and additional data were collected from interviews with parents, practitioners and the children themselves. Analysis of the data suggested that one way of understanding the variation in the children's experiences was through the ethnotheories, or cultural belief systems, of their home communities--such as their parents' concepts of childhood, and their theories of intelligence and instruction. The paper argues that such differences in children's home preparation have consequences for their school experience, and carry implications for their school providers. The study of parental ethnotheories, therefore, may help to explain, and alleviate, the differences in school achievement of children from diverse backgrounds. However, accessing respondents' personal theories presents both ethical and methodological problems, particularly when the researcher is working with socially disadvantaged groups.
