Nameability supports rule-based category learning in children and adults

The present study tested the hypothesis that verbal labels support category induction by providing compact hypotheses. Ninety-seven 4- to 6-year-old children (M = 63.2 months; 46 female, 51 male; 77% White, 8% more than one race, 4% Asian, and 3% Black; tested 2018) and 90 adults (M = 20.1 years; 70 female, 20 male) in the Midwestern United States learned novel categories with features that were easy (e.g., “red”) or difficult (e.g., “mauve”) to name. Adults (d = 1.06) and—to a lesser extent—children (d = 0.57; final training block) learned categories composed of more nameable features better. Children's knowledge of difficult-to-name color words predicted their learning for categories with difficult-to-name features. Rule-based category learning may be supported by the emerging ability to form verbal hypotheses.

Young children learning about living things: A case study of conceptual change from ontological and social perspectives

Although research from a developmental/psychological perspective indicates that many children do not have a scientific understanding of living things, even by the age of 10 years, little research has been conducted about how students learn this science topic in the classroom. This exploratory research used a case‐study design and qualitative data‐collection methods to investigate the process of conceptual change from ontological and social perspectives when Year 1 (5‐ and 6‐year‐old) students were learning about living things. Most students were found to think about living things with either stable, nonscientific or stable, scientific framework theories. Transitional phases of understanding also were identified. Patterns of conceptual change observed over the 5‐week period of instruction included theory change and belief revision as well as reversals in beliefs. The predominant pattern of learning, however, was the assimilation of facts and information into the students' preferred framework theory. The social milieu of the classroom context exposed students' scientific and nonscientific beliefs that influenced other individuals in a piecemeal fashion. Children with nonscientific theories of living things were identified as being least able to benefit from socially constructed, scientific knowledge; hence, recommendations are made for teaching that focuses on conceptual change strategies rather than knowledge enrichment. © 2004 Wiley Periodicals, Inc.

范畴学习中分类学习与推理学习的对比研究

实验室有关范畴学习的研究只局限于对分类的研究上,这就导致在分类研究基础上提出的范畴理论不能适用于其他非分类范畴学习任务。对分类学习与推理学习进行比较,表明不同的范畴学习类型影响范畴表征,所以应当拓展实验室范畴学习的研究范围。     

Young children learning about well-being and environmental education in the early years: a funds of knowledge approach

Early childhood educators currently provide content focused learning opportunities for children in the areas of well-being and environmental education. However, these are usually seen as discrete content areas and educators are challenged with responding to children’s interests in popular-culture inspired food products given these influence their consumption of energy-dense, nutrient-poor and highly packaged food in the early childhood setting. This paper reports preliminary findings from a pilot randomised trial examining the interconnectedness of sustainability, well-being and popular-culture in early childhood education. Planning, assessment documentation and summaries from twenty-four learning experiences implemented by six educators over a six-week period were analysed using a deductive approach. Twenty well-being and environmental education topics were identified and shown to be generated by the educators when considering the children’s ‘funds of knowledge’ on popular-culture inspired food products. We argue that topics derived from children’s engagement with popular-culture may help educators to create an integrated approach to curriculum provision. This may impact child weight and facilitate obesity prevention and environmental sustainability as children create stronger connections between these content areas and their everyday choices and practices.

Integration of a social skills training: a case study of children with low social skills

This study explores changes in children's social skills after a cognitive-social skills model intervention. The intervention was conducted over a period of 12 weeks within a regular preschool setting. Sixteen children including four considered to have low social skills participated in the study. Data analysis revealed that the four children with low social skills demonstrated changes in social skills through positive play behaviours such as asking positive questions, offering suggestions, initiating play episodes, and sharing play materials, although they had limited ability to maintain play episodes.     

Going on a journey: a case study of nature therapy with children with a learning difficulty

Therapy is usually described as an indoor activity, centring on verbal dialogue between therapist and client(s). Based on a qualitative study conducted with a group of children with learning difficulties, this article presents a way in which therapy can take place creatively in nature, which serves not only as a therapeutic setting but also as a non‐verbal medium and partner in the process. Using participants' voices to highlight the programme's protocol and impacts, the article presents elements from the innovative framework of nature therapy, offering practitioners concepts and methods that can be incorporated into their practice.

Strategy acquisition by children with general learning difficulties through metacognitive training

Children with general learning difficulties commonly show lower school success and have a slower rate of learning. They show limited and inefficient strategy use in all kinds of tasks. Efficient strategy use requires a certain degree of metacognitive knowledge and executive control. A sample of 16 children (ages 8 to 12) with learning difficulties participated in a 3-month metacognitive training intervention that alternated between curriculum-related and curriculum-unrelated tasks. The children were indirectly taught cognitive and metacognitive strategies by means of guided prompting. The application of the strategies and the children's metacognitive knowledge were evaluated through observation of their behavior and verbalizations. Children showed progress in strategy use and metacognitive knowledge in both types of tasks, but it was only in the more concrete strategies that a positive correlation was found between application and quality of reflection. It is hypothesized that children perceived these concrete strategies to be of most practical value and they were therefore able to reflect most accurately on their use.     

Contextual modulation of attention in human category learning

In a category-learning experiment, we assessed whether participants were able to selectively attend to different components of a compound stimulus in two distinct contexts. The participants were presented with stimulus compounds for which they had to learn categorical labels. Each compound comprised one feature from each of two dimensions, and on different trials the compound was presented in two contexts, X and Y. In Context X, Dimension A was relevant to the solution of the categorization task and Dimension B was irrelevant, whereas in Context Y, Dimension A was irrelevant and Dimension B was relevant. The results of transfer tests to novel stimuli suggested that people learned to attend selectively to Dimension A in Context X and Dimension B in Context Y. These findings contribute to the growing body of evidence that people can learn to selectively attend to particular dimensions of stimuli dependent on the context in which the stimuli are presented. Furthermore, the findings demonstrate that context-dependent changes in attention transfer to other categorization tasks involving novel stimuli.     

Young children's perceptionsof scientists: a preliminary study

Background

Since the 1950s, there has been a growing body of research dealing with perceptions children have of scientists. Typically, research studies in this area have utilized children's drawings in an effort to discern what those perceptions are. Studies assessing perceptions children have of scientists have shown that children have stereotypical images of scientists. Although there is no direct evidence to demonstrate the link between children's images of science and scientists with their career choice, several researchers (including this researcher) have assumed that children's attitudes towards science are greatly influenced by their perceptions of science and scientists.

Purpose

This study aimed to find out if there was a difference in the way 5- to 8-year-old children drew scientists, taking account of age, gender and socio-economic status.

Sample

For this study a convenience sample of 30 young children was used. Participants included young children between the ages of 5 and 8 years from a public elementary school in Ankara, the capital city of Turkey. Although the sample of the study was obtained from one school in a metropolitan area, children involved in this preliminary study were from very different socio-economic backgrounds. As the sample size is very small for making comparisons, it was intended to have a similar number of children from different age groups and socio-economic backgrounds and both genders.

Design and methods

The researcher worked individually with each child who participated in this study in an interview setting. Although each child was asked a set of standard questions, and given a standard set of directions, each interview session was informal enough to allow the researcher to gain additional information about children's drawings and to clarify any of their responses. During the interview sessions, children's responses were noted by the researcher. Before the children were asked to draw their picture of a scientist, they were offered a set of coloured pencils or crayons and told to feel free to colour their drawing or any parts of it they would like to accentuate. At the end of the interview and drawing sessions, the researcher went through all the drawings and notes to get a ‘feel’ for and ascertain what was being said, identifying key themes in each drawing.

Results

The most common scientist type drawn in this study was the stereotypical scientist type: someone who conducts research, or someone who tries to invent a new material. But unlike previous studies, around 35% of the scientist figures drawn (n = 15) were of the social scientist type. Stereotypical images drawn by the current study participants included symbols of research, such as scientific instruments and laboratory equipment of all kinds, and symbols of knowledge, principally books and cabinets, technology and the products of science. An interesting finding of this study was that perceptions of young children differed due to their age. Children at the age of 8 years drew non-stereotypical scientist images, and they drew more detail than did their younger peers. When children were compared in terms of their gender, no significant differences were observed between girls and boys. But on the other hand, none of the boys drew female scientists, and five out of 30 children who were girls drew female scientists. While children of parents with lower socio-economic status drew more stereotypical scientist images, children of parents with higher economic status drew different images of scientists, a result which showed us that the scientist perceptions of young children differ with socio-economic status.

Conclusions

Emergent from this research has been a non-stereotypical perception of scientists, and some evidence exists that such a non-stereotypical perception differs due to age and socio-economic status. While these images may seem amusing, they also provide a reflection of the image that children have about what a scientist looks like. These images may have a powerful impact on present functioning and future plans of young children.     

Effect of different training methods on perceptual learning in impulsive children.

The effectiveness of different training and transfer test conditions in promoting perceptual learning in impulsive kindergarten children was investigated. Interproblem variability was found to be more effective than intraproblem variability, and a differentiation training procedure was found to be more effective than a matching training procedure. The results provide guidelines for designing effective training methods for improving discrimination learning and problem solving in impulsive children.     

Lifelong learning and becoming a mother: evaluation of the Young Parents Program

The purpose of this research was to identify how lifelong learning has the potential to accommodate the changed circumstances and future needs of women who become mothers as teenagers. The research drew on the previously separate theories of lifelong learning and becoming a mother to frame this initial study. A qualitative case study was used to evaluate the Young Parents Program, which was devised to meet the informal learning needs of young mothers aged between 15 and 25 years. A total of eight mothers completed a survey and four of them also participated in a focus group interview to provide more in depth responses. The results indicate that the content of the programme provided relevant information that met the informal learning needs of the participants. The delivery of the programme helped participants to make connections with other young mothers in similar circumstances. The findings imply that informal learning programmes that respond well to the immediate needs of young mothers have the potential to prevent young mothers from becoming socially isolated. Young mothers who become engrossed in their own problems without access to relevant informal learning may fail to undertake formal learning opportunities that might be available in the future.     

Staff development needs and provision in Commonwealth countries: Findings from a Commonwealth of learning training impact study

The mission of the Commonwealth of Learning (COL) to provide staff development in open and distance education within the Commonwealth countries is noted. The paper then draws upon selected findings from the COL Training Impact Study (a study of 114 training events provided by COL over a 10-year period) and discusses the respondents' views on the needs and forms of provision that can be employed in providing staff training in open and distance education.
