Changes in Understandings of Three Teachers' Beliefs and Practice Across Time: Moving From Teacher Preparation to In-Service Teaching

Beliefs often guide a teacher's decision-making, thinking, and practice in the classroom (Vartuli, 2005 Vartuli, S. 2005. Beliefs: The heart of teaching. Young Children, 60: 76–86.  [Google Scholar]). There is limited longitudinal research on how early childhood preservice teachers develop new knowledge about their beliefs as they transition into in-service teaching positions (Joram & Gabriele, 1998 Joram, E. and Gabriele, A. J. 1998. Preservice teachers' prior beliefs: Transforming obstacles into opportunities. Teaching and Teacher Education, 14: 175–191. [Crossref], [Web of Science ®] , [Google Scholar]). Across 4 years that encompassed a series of three studies, this article chronicles three teachers' understandings of how their beliefs and practices were interrelated and informed by one another. Preservice teachers were interviewed and completed written reflections as they moved from under the umbrella of an undergraduate early childhood teacher preparation program into classrooms as in-service teachers. Findings reveal (a) how the preservice teachers' beliefs were initially unstable and nascent during Study One, (b) how a transactional nature between beliefs and practice began to emerge during Study Two, and (c) how, during Study Three, this relational exchange contributed to an increase in deliberate action as in-service teachers. Implications for early childhood teacher preparation programs include ensuring opportunities for preservice teachers to use self-reflection and inquiry across a range of course and field experiences as they identify and make connections between beliefs and practice.     

The Impact of a High Stakes Teacher Evaluation System: Educator Perspectives on Accountability

The use of student achievement data to evaluate an individual teacher's effectiveness has become a new focus in educational policy. This article focuses on the underresearched teacher perception of this new policy measure. Drawing on ethnographic research procedures, this article explores how first-grade teachers in one state navigated a new high-stakes teacher evaluation system. Although the results indicate that teachers have a desire for accountability, findings also show a variety of beliefs on the validity of teacher evaluation, as well as differing applications of scoring measures across school contexts.     

Change in atypical maternal behavior predicts change in attachment disorganization from 12 to 24 months in a high-risk sample

This longitudinal study examined links between disorganization and atypical maternal behavior at 12 and 24 months in 71 adolescent mother-child dyads. Organized attachment and maternal not disrupted behavior were more stable than disorganization and disrupted behavior, respectively. At both ages, disorganization and maternal disrupted behavior were significantly correlated. Change in atypical maternal behavior predicted change in disorganization across time. The results provide substantial support for extant theories linking anomalous maternal behavior to the development of disorganized attachment. The Interesting-but-Scary paradigm, introduced in this study, promises to be a useful tool for assessing attachment and maternal behavior in toddlerhood.     

Embracing inclusive teacher education

This paper examines the extent to which initial teacher education (ITE) programmes contribute to the development of inclusive attitudes, values and practices. Inclusive education is the entitlement of all children and young people to quality education, irrespective of their differences or dispositions. It is about embracing educational values of equity, diversity and social justice. The data which underpins this paper was obtained through research commissioned by the Department of Education (DE) Northern Ireland (NI) which sought to identify existing practices that increased the motivation, participation and achievement of all pupils of school age with special educational needs (Moran & Abbott, 2006 Moran, A. and Abbott, L. 2006. The development of inclusive schools in Northern Ireland: a model of best practice Northern Ireland Statistics and Research Agency, Research Report 42 [Google Scholar]). Head teachers and Special Educational Needs Coordinators (SENCOs) views were sought on the effectiveness of ITE programmes in preparing student teachers to work in inclusive school settings.

Cet article considère jusqu'à quel point les programmes de formation pédagogique initiale (ITE) contribuent au développement d'attitudes, de valeurs et de pratiques inclusives. Tous les enfants et les jeunes ont le droit à un enseignement de bonne qualite sans tenir compte de leurs différences, de leurs tendances ou de leurs infirmités. Il s'agit d'embrasser les valeurs éducatives de l'équité, de la diversité et de la justice sociale. Les données qui sont à la base de cet article ont été obtenues à partir de recherche commandée par le ministre de l'Education (DE) pour l'Irlande du Nord (NI) qui cherchait à identifier les pratiques actuelles qui ont augmenté la motivation, la participation et la performance de tous ceux qui ont des difficultés d'apprentissage scolaire (Moran & Abbott, 2006 Moran, A. and Abbott, L. 2006. The development of inclusive schools in Northern Ireland: a model of best practice Northern Ireland Statistics and Research Agency, Research Report 42 [Google Scholar]). On a demandé les opinions de Directeurs et de Coordinateurs pour l'enseignement spécialisé sur l'efficacité des programmes de formation pédagogique initiale (ITE) à préparer les enseignants stagiaires à travailler dans des établissements d'enseignement inclusif.

Este documento examina el punto hasta el que los programas iniciales de formación pedagógica contribuyan al desarrollo de actitudes, valores y prácticas inclusives. Todos los niños y los jóvenes tienen derecho a la enseñanza inclusive, o sea, de buena calidad, sin distinción de diferencia, temperamento ni discapacidad. Se trata de dedicarse a valores educativos de equidad, diversidad y justicia social. Los datos que respaldan este documento fueron obtenidos por medio de investigaciones encargadas por el Ministerio de Educación de Irlanda del Norte. Este pensó identificar prácticas actuales que aumentaran la motivación, la participación y el rendimiento de todos los alumnos de edad escolar que requirieran una educación especial (Moran & Abbott, 2006 Moran, A. and Abbott, L. 2006. The development of inclusive schools in Northern Ireland: a model of best practice Northern Ireland Statistics and Research Agency, Research Report 42 [Google Scholar]). Solicitaron las opiniones de los directores y de coordinadores de la educación especial respecto a la eficacia de los programas iniciales de formación pedagógica en lo que se refiere a preparar a los estudiantes de magisterio para trabajar en colegios con ambiente inclusive.

Dieses referat untersucht, inwieweit die ersten Lehrerausbildungsprogramme (ITE) zur Entwicklung von inklusiven Einstellungen, Werten und Praktiken beitragen. Inklusive Ausbildung bedeutet die Berechtigung aller Kinder und Jugendlicher zu einer erstklassigen Ausbildung, ungeachtet ihrer Unterschiede, Veranlagungen oder Behinderungen. Es geht um die Wahrnehmung der erzieherischen Werte von Fairness, Vielfalt und sozialer Gerechtigkeit. Die Daten in diesem Referat wurden anhand von Forschung im Auftrag des Kulturministeriums Nordirland (DENI) erworben, die versuchte, die bestehenden Verfahrensweisen zu identifizieren, welche die Motivation, Teilnahme und Leistungen aller schulpflichtigen Kinder mit besonderen schulischen Bedürfnissen förderten (Moran & Abbott, 2006 Moran, A. and Abbott, L. 2006. The development of inclusive schools in Northern Ireland: a model of best practice Northern Ireland Statistics and Research Agency, Research Report 42 [Google Scholar]). Schulleiter und Koordinatoren von Besonderen Schulischen Bedürfnissen (SENCOS) wurden befragt im Hinblick auf die Wirksamkeit von ITE‐Programmen, Referendare auf die Arbeit in inklusiven Schulumgebungen vorzubereiten.     

A simple classroom teaching technique to help students understand Michaelis-Menten kinetics

A new, simple classroom technique helps cell biology students understand principles of Michaelis-Menten enzyme kinetics. A student mimics the enzyme and the student's hand represents the enzyme's active site. The catalytic event is the transfer of marbles (substrate molecules) by hand from one plastic container to another. As predicted, increases in marble concentration increase the number of marbles transferred per unit time (initial rate, V(0)) until the turnover number becomes rate limiting and V(0) approaches the maximum velocity (V(max)), as described by the Michaelis-Menten equation. With this demonstration, students visualize an important concept: the turnover number is constant and independent of marble concentration. A student assessment of this exercise showed that it helped students visualize the turnover number and V(max) but not K(m), the marble concentration at which V(0) is one-half V(max). To address the concept of K(m), we use supplemental laboratory and lecture exercises. This exercise with plastic containers and marbles is equally suited to demonstrate the kinetics of carrier-mediated membrane transport. We conclude that this exercise helps students visualize the turnover number and V(max) and gives students important insights into the kinetic parameters used to characterize the catalytic activity of enzymes and membrane transporters.

Northern Ireland beginning teachers' experiences of induction: the ‘haves’ and the ‘have nots’

The induction of beginning teachers continues to occupy a significant position on educational policy agendas as a crucial dimension in the formation of a teacher and one upon which an emergent career is built. Whilst there is growing impetus to establish an induction model that constitutes a relevant, fulfilling experience, current arrangements continue to vary throughout the UK. This paper describes induction as it affected a sample of beginning teachers in Northern Ireland, where there is a dearth of permanent positions for those newly qualified. Highly contrasting experiences of the induction year emerged between graduates in permanent and one‐year temporary positions, and those who were short‐term temporary and supply teachers. The former completed a meaningful induction whereas the latter, because of sporadic, fragmented employment, did not. A flexible model of induction is proposed, with collaborative involvement of the higher education institutions, the schools and the local education authorities.
