Exploring Estimation in Young Primary School Children

There is an increasing emphasis in mathematics education on the importance of estimation abilities in children. This study investigates the role of context upon primary‐aged children's estimation skills. Children in three age groups (from aged 5 to 8 years) were asked to carry out a range of estimation tasks involving distance, area and volume measurements. The tasks varied in type and complexity and were either of a ‘real‐world’ or ‘mathematics task’ form. In addition to performance measures the children's answers to questions on how they carried out the estimates were recorded and analysed. Quantitative and qualitative analyses found significant effects for context and child strategy. Estimates in contexts perceived as mathematical were different, both in that they changed with age and in their error patterns, from contexts involving perceptual‐motor skills. The children's answers highlight the importance of imagery and classroom experience. The results are discussed within a model of estimating.

Addressing bullying through critical making

This paper explores how maker pedagogies helped middle school students develop transferable competencies, such as creativity, problem solving, self-directed learning and citizenship skills. We offer an in-depth look at how purposeful or critical making related to bullying awareness can help struggling students develop positive attitudes related to their roles as contributing members of a classroom community of learners.     

Research on Language and Communication in Children who have Severe Handicaps: a review and some implications for intervention

Abstract This paper presents a critical discussion of some contemporary literature on the language development of, and problems in communication for, persons with severe handicaps. For meaning to be transmitted from one person to another requires a social interactive context. These transactional exchanges begin very early in a child's life and carry particular implications for caregivers and therapists. Some implications of this literature for intervention are suggested.     

Locomotor activity and exploration: The use of traditional manipulators to dissociate these two behaviors in the rat

An apparatus designed by Berlyne was used to dissociate locomotor activity and inspective exploratory responses with the aid of traditional manipulators. In this apparatus, novel and complex stimulation increased exploration but did not affect locomotor activity (LA), d-amphetamine (1.5 mg/kg) increased LA but decreased exploration. These findings provide a double dissociation of the behavioral components. In addition, low intrasubject correlations for the two behaviors were demonstrated. Results are discussed with reference to the need for simultaneous separate measures to obtain valid indices of exploratory behavior and LA.     

Learning and nonlearned neophobia enhancement both contribute to the formation of illness-induced taste aversions by deer mice (Peromyscus maniculatus bairdi)

An investigation was made of the occurrence of learned and nonlearned aversions in the acquisition of illness-induced taste aversions in mice of the genusPeromyscus. It was determined: (1) that illness following the ingestion of a novel flavor both produced aversions specific to that flavor and also enhanced neophobia directed toward novel flavors in general; (2) that the specific aversion and the enhanced neophobia appeared to be mediated by independent processes, with no indication that the enhanced neophobia was dependent upon the integrity of the specific aversion; and (3) that illness following the ingestion of familiar water produced enhanced neophobia, which did not appear to be mediated by an aversion to water. It was noted that the results were fundamentally in agreement with those previously obtained with laboratory rats, except that a demonstration of the independence between the two types of aversions has not yet been reported in those animals.
