Children's learning about the balance scale

We present a detailed look at children's learning about the balance scale. In our study, as children explored the balance scale, they acquired and built on special-case and context-specific knowledge. Before making general and context-independent observations, they made more local observations.We contrast our findings with two previous analyses of children's knowledge [Inhelder and Piaget, 1958; Siegler, 1978] about the balance scale in light of assumptions about the nature of knowledge and its acquisition. Educational implications of all three analyses are considered.     

Dilemmas of Participatory Enquiry: a case study of method‐in‐action

The purpose of this paper is to problematize the notion of participatory enquiry as a legitimate form of educational evaluation. Using a case study of a new teacher education program the authors describe how they negotiated and enacted an alternative evaluation methodology within a traditional context. The evaluation process was intended to actively engage faculty members and students, as well as representatives of the educational system and the broader community, in self‐reflection and self‐evaluation of their own program. The authors then attempt to turn the methodology back on itself by critically analyzing their own participatory process in terms of a number of dilemmas that arose during the three‐year course of the evaluation. These dilemmas were addressed directly as political issues of method as a means of eliciting discussion and debate about the appropriateness of various forms of enquiry in the assessment and evaluation of higher education.     

Factors in the development of proportional reasoning strategies by concrete operational college students

This study was designed as a test for two neo-Piagetian theories. More specifically, this research examined the relationships between the development of proportional reasoning strategies and three cognitive variables from Pascual-Leone's and Case's neo-Piagetian theories. A priori hypotheses linked the number of problems students worked until they induced a proportional reasoning strategy to the variables of M-space, degree of field dependence, and short-term storage space. The subjects consisted of students enrolled in Physical Science I, a science course for nonscience majors at the University of Southern Mississippi. Of the 34 subjects in the study, 23 were classified as concrete operational on the basis of eight ratio tasks. Problems corresponding to five developmental levels of proportional reasoning (according to Piagetian and neo-Piagetian theory), were presented by a microcomputer to the 23 subjects who had been classified as concrete operational. After a maximum of 6 hours of treatment, 17 of the 23 subjects had induced ratio schemata at the upper formal level (IIIB), while the remaining subjects used lower formal level (IIIA) schemata. The data analyses showed that neither M-space and degree of field-dependence, either alone or in combination, nor short-term storage predicted the number of problems students need to do until they induce an appropriate problem-solving strategy. However, there were significant differences in the short-term storage space of those subjects who mastered ratio problems at the highest level and those who did not. Also, the subjects' degree of field-dependence was not a predictor of either the ability to transfer problem-solving strategies to a new setting or the reuse of inappropriate strategies. The results of this study also suggest that short-term storage space is a variable with high correlations to a number of aspects of learning such as transfer and choice of strategy after feedback.     

Teaching Chronobiology and Sleep Habits in School and University

ABSTRACT— Early morning school schedules are in the opposite direction to the sleep–wake cycle in adolescence and early adulthood. This conflict leads to sleep deprivation and irregular patterns whose consequences are scarcely explored. This article discusses the effects of three educational experiences with high school students, parents, teachers, and medical students. The first experience was developed with high school students in Natal, Brazil, to determine whether sleep habits would improve with increased awareness. Positive effects were observed in some aspects of sleep knowledge and practices. In the second experience in Atlanta, GA, sleep education activities were presented to middle and high school teachers, parents, and students to emphasize the importance of sleep. In the third program in Murcia, Spain, undergraduate medical students were introduced to chronobiology of sleep by a practical exercise that pointed out to what extent they shared most of adolescent sleep characteristics. Educational chronobiological experiences about sleep are essential to develop healthy sleep habits in the general population, particularly in students.     

Exploring identities and cultures in inter-professional education and collaborative professional practice

Although the concept of multi-agency working has been pursued and adopted as the most appropriate way to improve childcare provision and health workforces in recent years, both in the UK and more globally, research suggests that participation in such work can be problematic. This article examines current developments in inter-professional education and collaborative professional practice. Drawing on desk research across the fields of Education, Health and Social Care, it applies a critical lens to re-examine inter-professional working using well-established concepts of profession, identity, culture, career, and training/work transitions. The article uses theoretical hooks to look for similarities and differences in the promotion of inter-professionality across the Education, Health and Social Care sectors, alongside those which occur within each. It looks towards a re-invigoration of knowledge creation and application through research. This is viewed as especially urgent in times of fragmentation, transformation, and arguably, disintegration, in the services its professional and academic educators and workers seek to serve.     

Fabrication of an Ultrasonic Nebulizer: Rate of Flow and Performance Studies

ABSTRACT

This article describes how to build, in-house, a new type of ultrasonic nebulizer and presents the results of tests to determine its rate of aqueous flow and its performance during the transport of a collagen-based adhesive (ratio of adhesive actually delivered to adhesive misted). It also reports on a consolidation treatment case study carried out with the new ultrasonic misting prototype: the NebulA-MG 14. This case study was applied to powdery paint layers of a medium-sized oil painting on canvas, 111.5?×?86.5?cm. The new device is shown to be both reliable and effective, particularly for consolidating medium and large-sized works.     

Moral education: dilemmas for the teacher

ABSTRACT

The paper examines recent developments in food‐focused education following the implementation of the 1988 Education Reform Act. Drawing on data from an ESRC‐funded project on Teaching and Learning about Food and Nutrition in Schools (1993‐4), the paper explores evidence which demonstrates a marginalized and fragmented curriculum for food, and considers its implications. The paper comprises two sections. The first focuses on literature and curriculum documentation available at the start of the research and examines the formal corpus of school knowledge about food. This informs the second section which draws on data collected during case‐studies of four English secondary and primary schools and on what the data tell us about the food curriculum and its implications for transmission in the case‐study schools. Specific examples highlight issues of diversity, ambiguity and contradiction in implementation. Conclusions emphasize the need for greater curriculum coherence in policy and practice and for a reassessment of the framing and interpretation of food knowledge and skills. In the absence of systematic evaluations, schools continue to replicate rather than challenge the contradictions in understandings about food use which are documented features of the adult population in general.     

ENGLISH LANGUAGE PROFICIENCY AND TEST PERFORMANCE: AN EVALUATION OF BILINGUAL STUDENTS WITH THE WOODCOCK‐JOHNSON III TESTS OF COGNITIVE ABILITIES

In this article, we report the findings of an exploratory empirical study that investigated the relationship between English Language Proficiency (ELP) on performance on the Woodcock‐Johnson Tests of Cognitive Abilities‐Third Edition (WJ III) when administered in English to bilingual students of varying levels of ELP. Sixty‐one second‐grade students, identified as Limited English Proficient, were recruited from a suburban public school district and were given the WJ III in addition to their annual state standardized assessment of ELP. The findings of this study provide evidence to support a linear, inverse relationship between ELP and performance on tests that require higher levels of English language development and mainstream cultural knowledge. The implications of the findings of the present study suggest that practitioners must consider an examinee's level of developmental language proficiency and cultural knowledge acquisition as continuous variables when determining the impact of such factors on test performance and evaluation regarding whether scores obtained from tests administered in English are indeed valid for interpretation.
