Errors in children's subtraction

Many of the errors that occur in children' subtraction are due to the use of incorrect strategies rather than to the incorrect recall of number facts. A production system is presented for performing written subtraction which is consistent with an earlier analysis of the nature of such a cognitive skill. Most of the incorrect strategies used by schoolchildren can be accounted for in a principled way by simple changes in the production system, such as the omission of individual rules or the inclusion of rules appropriate to other arithmetical tasks. The production system model is evaluated against a corpus of over 1500 subtraction problems done by 10-year olds and is shown to account for about two-thirds of the (nonnumber fact) errors. It also provides an alternative, simpler interpretation of the subtraction errors analysed by Brown and Burton (1978). Some implications for teaching are discussed.     

The Subtle Temptations of State Sponsored Theological Education: A New Zealand Perspective

Abstract. Over the past fifteen years in New Zealand, theology has come in from the tertiary educational cold in various ways. One of the results or reasons for this has been willingness on the part of the state to accredit and provide funding for theological education and research. This has taken place largely through a compliance system of accreditation and resource allocation. The result has been academic recognition and a precarious financial boon for theology and some theological institutions and their students. But little attention has been paid to the epistemological and pedagogical temptations of compliance. Drawing on the recent experience of the writer, this article seeks to identify a number of the subtle temptations posed by state sponsored theological education and research.     

The effects of the age of eyewitnesses on the accuracy and suggestibility of their testimony

Previous studies have compared the performance of young adult eyewitnesses with that of children or elderly eyewitnesses, but few studies have allowed direct comparison of the performance of all three age groups. The accuracy and suggestibility of accounts of a video recording of a kidnapping were investigated using an experimental eyewitness paradigm. Subjects were drawn from three age groups: children (aged 7–9 years); young adults (aged 16–18 years) and elderly subjects (aged 60–85 years). Subjects' accuracy in answering non-misleading questions and their susceptibility to misleading information was measured. Both the elderly and child subjects gave fewer correct answers and more incorrect answers to non-misleading questions than did young adults. The elderly subjects gave fewer correct responses but also fewer incorrect responses to non-misleading questions than did child subjects. Children were more suggestible than either elderly or young adults. No significant difference was found in the suggestibility of elderly and young adults. Contrary to the trace strength hypothesis no relationship was found between accuracy of recall and suggestibility. © 1997 John Wiley & Sons, Ltd.

Neutrality, Rebirth and Intergenerational Justice

A basic feature of liberal political philosophy is its commitment to religious neut-rality. Contemporary philosophical discussion of intergenerational justice violates this com-mitment, as it proceeds on the basis of controversial metaphysical assumptions. The Contractualist notion of a power imbalance between generations and Derek Parfit's non-identity claims both presuppose that humans are not reborn. Yet belief in rebirth underlies Hindu and Buddhist traditions espoused by millions throughout the world. These traditions clearly constitute what John Rawls dubs "reasonable comprehensive doctrines", and therefore cannot be dismissed by political liberals. In many societies, including the USA, the UK, and India, belief in rebirth exists alongside other traditions, as well as modern Western views. A liberal theory for such societies must be impartial regarding rebirth, and the after-life in general. Two alternatives forms of liberal neutrality are sketched, based on Contractualism and Consequentialism.     

Sociality and intergenerational transfer of older adults’ nostalgia

Interest in nostalgia has blossomed, yet its nature in older adulthood and potential for intergenerational transfer to younger adults has remained neglected. In Experiment 1, we focused on the content of older adults’ nostalgic (vs. ordinary) recollections and asked whether older adults’ nostalgia could be transferred to younger adults. We showed that nostalgia expressed in older adults’ narratives was positively associated with nostalgia reported by young-adult readers. In Experiment 2, undergraduates read a nostalgic or ordinary narrative written by an older adult. Then they rated their own nostalgia as well as their perceived social connectedness, self-continuity, and meaning in life. Exposure to older adults’ nostalgic (vs. ordinary) narratives promoted concurrent nostalgia among young adults, along with associated psychological benefits (social connectedness, self-continuity, meaning). The findings illustrate the potential for intergenerational transfer of nostalgia through written narratives, and attest to the universality of nostalgic themes across younger and older adults.     

Cultural values and attitudes towards guidance and counselling services in one secondary school in Malaysia: the role of a school cultural system

This narrative ethnographic study aims to explore students' attitudes towards guidance and counselling services in one secondary school in Malaysia. Semi-structured individual interviews, group interviews and observations were conducted with school students of different racial backgrounds. They were identified as referred clients, self-referred clients, and those not deemed to be involved in counselling. The data were analysed using the constant comparative analysis grounded theory approach. The findings indicate that there were different attitudes among the three groups of participants concerning counselling services. The study highlights the role of a school system in elucidating attitudes towards guidance and counselling services. It poses implications for understanding counselling services within the school system.
