Conditioning with taste as the CS in conditioned flavor preference learning     

Elizabeth D. Capaldi  Martin J. Hunter  Sandra A. Lyn 《Learning & behavior》1997,25(4):427-436

There appear to be unconditioned affective reactions to the four basic tastes: liking for sweet and salt and disliking for sour and bitter. We attempted to modify these reactions by pairing the tastes with calories and with sweeter tastes. Differing sucrose concentrations were ineffective in reversing the preference for salt over citric acid or for saccharin over quinine. We could, however, reverse the preference for salt over citric acid, producing an actual preference for sour over salt, by using sucrose and saccharin as the reinforcers. The initial reactions to tastes could also be modified by reducing the initial difference in affect produced by the tastes through mixing both tastes with sucrose.  相似文献   

Sharing teacher knowledge at scale: teacher inquiry,learning design and the representation of teachers’ practice     

Martin Oliver  Katerina Avramides  Wilma Clark  Jade Hunter  Rose Luckin  Cecilie Hansen 《Teacher Development》2018,22(4):587-606

Sharing teachers’ professional knowledge remains challenging. Teachers’ development often remains ad hoc or local, and attempts to scale this up have proved problematic. To address this, research in areas such as ‘learning design’ has explored the use of formal representations of practice. This proposes that educational practice can be improved by documenting, sharing and building on what teachers already do. Whilst this has led to some successes, it has not resulted in the widespread transformation of practice. This paper reviews the literature about sharing teacher knowledge. The challenges of scaling up development are then considered in relation to two theories that help explain the challenges: Communities of Practice and Sociomateriality. This analysis is illustrated through case studies in Norway and the UK. These show that teachers already create and share artefacts that represent their pedagogic knowledge. However, they found formal representations, such as learning designs, difficult to work with. The paper concludes that scaling up teacher development using abstract formalisms is unlikely to succeed. Instead, teachers value stories and the materials they already create in their day-to-day practice. It is this intermediate level of representation, between direct experience and formal abstraction, that offers the most promise for sharing practice.  相似文献   

Extinction and food-reinforced inhibition of conditioned salivation in dogs     

Dennis L. Herendeen  Martin M. Shapiro 《Learning & behavior》1975,3(2):103-106

The present experiment compared two methods of eliminating a classically conditioned response in dogs, extinction and reinforcement of nonsalivation, using both a within- and between-subjects experimental design. Eighteen dogs were trained for 16 days in Phase I, 16 days in Phase II, and 8 days in Phase III. In Phase I, each subject received classical conditioning training to two stimuli. In Phase II, Group 1 received extinction training to one stimulus and reinforcement of nonsalivation to the other stimulus. Group 2 received continued classical conditioning training to one stimulus and reinforcement on nonsalivation training to the other. Group 3 received continued classical conditioning training to one stimulus and extinction training to the other. In both the within- and between-subjects comparisons, responding to the stimulus associated with extinction was eliminated faster than responding to the stimulus associated with reinforcement of nonsalivation.  相似文献   

Disentangling the relationship between working memory and language: The roles of short-term storage and cognitive control     

Pascale Marguerite Josiane Engel de Abreu  Susan Elizabeth Gathercole  Romain Martin 《Learning and individual differences》2011,21(5):569-574

This study investigates the relationship between working memory and language in young children growing up in a multilingual environment. The aim is to explore whether mechanisms of short-term storage and cognitive control hold similar relations to emerging language skills and to investigate if potential links are mediated by related cognitive abilities. A sample of 119 Luxembourgish 6-year-olds completed several assessments of working memory (complex and simple span), native and foreign vocabulary, syntax, reading, rhyme awareness, and fluid intelligence. Results showed that short-term storage and cognitive control manifested differential links with developing language abilities: Whereas verbal short-term storage was specifically linked to vocabulary; cognitive control manifested unique and robust links with syntax and early reading development. The study suggests that in young children the working memory system is composed of separate but interacting components corresponding to short-term storage and cognitive control that can be distinguished by the roles they play in supporting language acquisition.  相似文献   

Systemic action and learning in public services   总被引：1，自引：1，他引：0  

Clare Rigg 《Action Learning: Research and Practice》2011,8(1):15-26

Complex, systemic issues continue to challenge public services without respect for organisational and professional boundaries. In practice, collaborative working with others who have differing professional cultural norms and systems confront members with the need to learn about each other's values, priorities and practices. This paper explores the potential of action learning for the development of systemic leadership capabilities within public services. Starting from core principles it is argued that action learning be seen not simply as a small group process for problem-solving or individual development, but as a collective process for inquiring into and taking action on projects and practices within their complex, multi-agent contexts.  相似文献   

A Dual Identity Approach for Conceptualizing and Measuring Children's Gender Identity          下载免费PDF全文

Carol Lynn Martin  Naomi C. Z. Andrews  Dawn E. England  Kristina Zosuls  Diane N. Ruble 《Child development》2017,88(1):167-182

The goal was to test a new dual identity perspective on gender identity by asking children (n = 467) in three grades (M_age = 5.7, 7.6, 9.5) to consider the relation of the self to both boys and girls. This change shifted the conceptualization of gender identity from one to two dimensions, provided insights into the meaning and measurement of gender identity, and allowed for revisiting ideas about the roles of gender identity in adjustment. Using a graphical measure to allow assessment of identity in young children and cluster analyses to determine types of identity, it was found that individual and developmental differences in how similar children feel to both genders, and these variations matter for many important personal and social outcomes.  相似文献   

Year 5 pupils reading an "Interactive Storybook" on CD-ROM: losing the plot?     

John Trushell  Clare Burrell  & Amanda Maitland 《British journal of educational technology : journal of the Council for Educational Technology》2001,32(4):389-401

The use of "interactive storybooks" in the primary classroom may facilitate small group and individual reading with minimal teacher intervention. This small-scale study examines whether small groups of Year 5 pupils, without teacher supervision, progress linearly through an "interactive storybook" and whether such diversions as cued animations affect pupil comprehension. The study finds that more intensive choice of diversions affects some pupils' comprehension.  相似文献   

Counselor Educators' Experiences Preparing Preservice School Counselors: A Phenomenological Study          下载免费PDF全文

Jennifer Scaturo Watkinson  Emily C. Goodman‐Scott  Ian Martin  Kathy Biles 《Counselor Education & Supervision》2018,57(3):178-193

The authors conducted a phenomenological study to explore the experiences of 32 school counselor educators preparing preservice school counselors. Analysis of data from 3 focus groups revealed 3 themes: breadth versus depth, balancing specialties and professor partiality, and preparation versus practice. These results highlight the need for collaboration across counseling specialties at the preservice level.  相似文献   

„Jeder Schule ihre Lehrer“?     

Eva Treptow  Martin Rothland 《Zeitschrift für Erziehungswissenschaft》2005,8(2):305-320

Neue Personalauswahl- und Einstellungsverfahren, an denen die Einzelschulen ma?geblich beteiligt werden, kommen bei der Besetzung von Lehrerstellen in zahlreichen Bundesl?ndern seit Mitte der 1990er-Jahre zur Anwendung und haben mittlerweile die herk?mmlichen zentralen Auswahl- und Zuweisungsverfahren zumindest in einigen von ihnen nahezu vollst?ndig abgel?st. Die Praxis und Wirkung der neuen Auswahlverfahren wurde bislang allerdings nicht systematisch untersucht. In diesem Beitrag werden empirische Befunde einer Untersuchung von Schulen in Nordrhein-Westfalen vorgestellt, die im Jahr 2002 freie Lehrerstellen über das neue Ausschreibungsverfahren besetzt haben. Erfasst wurden unter anderem die in der Praxis angewandten Kriterien der Personalauswahl und die Inhalte der Auswahlgespr?che, die Beurteilung des neuen Auswahl- und Einstellungsverfahrens durch die beteiligten Schulleitungen und Mitglieder der Auswahlkommissionen, Einsch?tzungen und Erfahrungen der neu eingestellten Lehrkr?fte sowie der Verlauf ihrer Berufseinstiegsphase und ihre Bew?hrung am neuen Arbeitsplatz.  相似文献   

Deaf teacher candidates in hearing classrooms: a unique teacher preparation program     

Martin DS  Lytle RR 《American annals of the deaf》2000,145(1):15-21

An undergraduate teacher education program at Gallaudet University prepares deaf students in "regular" education. This includes a required full-time internship with hearing students (assisted by sign language interpreters). Graduates then continue in a master's degree program in deaf education, thus acquiring dual certification. Several studies indicate that these deaf candidates progress through the same developmental stages as hearing candidates and that they develop high expectations for deaf learners. Issues related to implementing such a program are discussed.  相似文献
