An essay on error

In recent years, researchers have started to take an increasing interest in errors that can frustrate teaching and training and learning. These enquiries have, however, tended to be of a special-purpose kind in the sense that they have focused on particular learning domains such as language learning, mathematics learning, and the acquisition of perceptual-motor skills. What is lacking is a more global approach to the problem of error or even, for that matter, a recognition that a global approach might be both possible and informative. This article tries to rectify this gap in the theoretical literature by indicating, in a comparatively discursive and non-rigorous way, the form that such an overall theory of error might take.     

Preferential looking as a measure of visual resolution in infants and toddlers: a comparison of psychophysical methods

We used preferential looking to estimate the monocular visual resolution of children 6-36 months old and compared results from 3 psychophysical methods: Taylor and Creelman's PEST staircase, our modification of the PEST procedure, and the method-of-constant stimuli. Estimates of visual resolution for 48 children tested with the original and modified PEST procedures and for 50 children tested with the method-of-constant stimuli and the modified PEST procedure showed excellent agreement across procedures, with the modified PEST procedure requiring the fewest trials and the least time. Results from the modified PEST procedure for 168 children with normal eye alignment and minimal refractive errors indicated that monocular visual resolution improves from 6.5 min at 6 months to 1.2 min at 36 months. Preferential looking combined with the shortened PEST procedure should be useful for testing the visual resolution of preverbal children with eye problems.     

Educating Community Intellectuals: Rhetoric, Moral Philosophy, and Civic Engagement

This article encourages technical and professional communication programs to take on the challenge of educating students to become “community intellectuals.” The notion of educating future professionals for a career needs to be reconsidered in light of both current research concerning civic rhetoric and past practices in moral humanism courses. The triumvirate of rhetoric, ethics, and moral philosophy provides an effective foundation for reconfiguring existing pedagogy in the field and offers insights for nurturing community intellectuals.     

Changes in parent-child interaction in response to intervention

Parent-child interactions during the early years form the basis of many types of skill acquisitions, including fine motor and communication skills. Early intervention programmes aimed at promoting the attainments of children with disabilities or learning delays often suggest ways in which parents can interact with their children. The present study examined whether such intervention changes the nature of the parent-child interaction, using two groups of typically developing infants. The mothers of these two groups of prelinguistic children aged 10–12 months and 17–18 months were recorded talking to their infants when playing with a toy and then when asked to encourage their child to play in a particular way. Analyses of the affective and perceptual salience of the pitch of the mothers’ voices indicated that with the younger infants, but not the older infants, both the affective quality and the dynamic range of the mothers’ voices was reduced in the second condition. It is argued that this reduction enables the younger infants to concentrate on the task but restricts access to the linguistic content of what is said. The implications of these findings for intervention programmes are discussed.     

Initial Experiences of Creating Multimedia Computer Simulations to Replace Pharmacology Practicals

The replacement of traditional practicals by CAL simulations was prompted by a combination of economic factors, a decreased level of technical support and the requirement for a large capital investment to replace old and broken equipment. In an economic climate which promised only further increases in the number of undergraduates and no assured commensurate increase in resources, CAL appeared to be a possible alternative (Brown et al , 1988). Our only previous attempt to produce our own CAL package had been written in Turbo Basic on a 286 PC. It had involved considerable time and effort and the results were not particularly realistic. The increase in computing power offered by the 486 series of PCs, availability of low cost sound and video capture expansion cards, and the emergence of authoring systems, such as Toolbook, Hypercard and Authorware , appeared to provide an opportunity to produce better simulations (Purcell, 1993; Hartley, 1993).     

The relationship between neonatal characteristics and three-month mother-infant interaction in high-risk infants

The behavior of 4 groups of infants--healthy term, healthy preterm, sick preterm, and sick full-term--was assessed in the neonatal period using the Neonatal Behavioral Assessment Scale (NBAS). At 3 months postterm, infants and their mothers were observed and videotaped in a free-play session. Both the NBAS and mother-infant interaction data were analyzed to assess the effects of maturity (term vs. preterm), illness (sick vs. healthy), and their interaction. Results revealed that illness of the infant affected both NBAS performance and maternal behavior during the interaction at 3 moths. Infants who were ill performed poorly on the NBAS orientation dimension; this dimension was found to be significantly associated with maternal and infant behaviors at 3 months. These data demonstrate an association between early infant characteristics and subsequent mother and child interactive behaviors. They also identify postnatal illness as an important influence on the development of the mother-infant dyad.     

The Persistent Life of Oppression: The Unconscious,Power, and Subjectivity

The rise of standardization signals that Paulo Freire's critique of the banking concept of education continues to be relevant today. But Freire's theory of critical pedagogy has not gone without its critiques. On the one hand, the fact that these criticisms exist should not blind us to the fact that Freire's intention was to formulate an emancipatory pedagogy because of oppressive systems of education. On the other hand, we cannot continue Freire's project without heeding the warnings issued by these criticisms. In this paper, we address pressing issues concerning Freire's libratory pedagogy and the way it has been taken up by recent Marxist theorizing in education while at the same time maintaining the importance for thinking through an emancipatory pedagogy. We are clear: the real culprit in this situation is the persistent life of oppression itself. We utilize psychoanalysis and the theories of Michel Foucault in order to pinpoint and work through a specific problematic concerning Freire's theories – namely: oppression has an existence in the unconscious such that those who are oppressed form passionate attachments to the forms of power that oppress them. Indeed, such a problematic is not flattering for all who are concerned with forms of social oppression, but, we contend, that unless this problem is recognized and worked through, no real liberation is possible     

Paradigm revisited: Another look at the physical and social sciences

The study reexamines the paradigm concept as presented by Lodahl and Gordon with respect to the concept of consistency in professional life. The results show that high paradigm disciplines are more consistent than low paradigm disciplines on selected measures of educational background and professional activity. The conclusions of this investigation suggest first that the paradigm concept works well by itself in researching academic professions, and second that the concept of consistency offers a new way of both classifying faculty and exploring the dimensions of faculty characteristics.     

The State of the Literature on Student Evaluations of Teaching and an Exploratory Analysis of Written Comments: Who Benefits Most?

The purpose of this exploratory analysis is to review the state of the literature on student evaluations (SEs) of teaching and examine to what extent an instructor's race/ethnicity influences student's qualitative comments. Also, does the intersection of race and gender influence student's qualitative comments on SEs? Utilizing an online survey distributed among various organizational listserv in the discipline of Political Science, this study highlights written comments received on SEs by faculty generally. Additionally, we hope to contribute findings that support how negative comments may affect faculty of color and women.     

Development of self-recognition, personal pronoun use, and pretend play during the 2nd year

This study examined the relation of visual self-recognition to personal pronoun use and pretend play. For a longitudinal sample (N=66) at the ages when self-recognition was emerging (15, 18, and 21 months), self-recognition was related to personal pronoun use and pretend play such that children showing self-recognition used more personal pronouns and demonstrated more advanced pretend play than did children not showing self-recognition. The finding of a relation among these measures provides additional evidence that in the middle of the 2nd year of life a metarepresentation of self emerges in the human child.
