Acquisition and extinction of differential responses to signals paired with shock or shock omission in goldfish: Evidence for truly discriminated avoidance learning     

Dominic J. Zerbolio  Joel L. Royalty 《Learning & behavior》1982,10(3):377-389

Goldfish trained to discriminate between signals paired with shock (S?) and signals paired with shock omission (S+) with a linear presentation procedure, originally learned (OL) to control the signal state of a shuttle box and showed a decided preference for the S+ signal. In Experiment 1, following OL, groups had one OL signal replaced (S+ or S?), both signals replaced (S+ and S?), or the OL signals reversed (S+ and S? reversed) and were then tested in a transfer training procedure. In transfer, groups with one signal replaced maintained discriminated performance at OL levels; the S+ replaced group was slightly superior to the S? replaced group on the first day of transfer. With both OL signals replaced, discrimination dropped to chance performance levels, whereas, with OL signal shock pairing reversed, discrimination performance dropped below chance levels. In Experiment 2, following OL, extinction procedures consisted of turning off the shocker (0% shock) or of shocking 100% or a random 25% of the trials. A fourth extinction procedure (R,) retained the trial start response-dependent shock-omission contingency, but shock differentiating the S+ and S? signals was eliminated entirely. Extinction of the S+/S? discrimination was measured both during extinction training per se and with reversal retraining of the S+/S? discrimination later. Groups for which the OL S+ was paired with shock during extinction extinguished on both measures, but groups for which the OL S? was paired with shock omission did not extinguish, especially as shown by the reversal test procedure. Theoretical implications and the implications for several conditioning procedures are discussed.  相似文献   

Linguistic and Cultural Appropriations of an Immigrant Multilingual Literacy Teacher Educator     

Patriann Smith  S. Joel Warrican  Alex Kumi-Yeboah 《Studying Teacher Education》2016,12(1):88-112

This autoethnographic self-study describes my interpretations of multicultural awareness, with special attention to multilingual awareness (MLA), based on my interactions with 52 students in the context of two literacy courses over a period of one year. An autoethnographic self-study provided an avenue to harness my reflections on practice and to study the ways in which my practice reflected awareness of my role as an educator. Findings from my teaching videos, written responses to students, and student evaluations suggested that my communication patterns with students reflected certain elements of multicultural awareness, as displayed by my attention to individual predispositions, cultural practices and personal stereotypes. The findings also appeared to indicate that multicultural and MLA interacted to reflect facilitation and symbiosis. Facilitation seemed apparent in my awareness of differences among students’ cultures and my own as I monitored my linguistic processing. Symbiosis appeared to emanate from the recognition of how my response to individual predispositions facilitated my application of conversational strategies based on feedback. This, in turn, heightened my attention to stereotypical attitudes and behaviors. Implications for multicultural teacher education include the benefits of using autoethnographic self-study to scrutinize educators’ awareness in practice as they determine the impact of this awareness on their instructional roles in multicultural teacher education. By extension, the study suggests that autoethnographic self-study research can provide additional lenses through which to interrogate monolithic perceptions of diversity in multicultural teacher education.  相似文献   

What time-series designs may have to offer educational researchers     

Thomas R. Kratochwill  Joel R. Levin 《Contemporary educational psychology》1978,3(4):273-329

The promise of time-series designs for educational research and evaluation is reviewed. Ten time-series designs are presented and discussed in the context of threats to internal and external validity. The advantages and disadvantages of various visual and statistical data-analysis techniques are presented. It is argued that time-series research paradigms are useful when researchers (a) wish to involve a single subject in experimental research (individuals as units of analysis) or conduct program-evaluation studies (aggregates as units of analysis), (b) are interested in nearly continuous measurement, (c) cannot meet conventional design and statistical assumptions, or (d) wish to specify individual differences through N = 1 research strategies. It is also suggested that more research endeavors be devoted to combining unique characteristics of time-series research with conventional multi-unit paradigms.  相似文献   

Enhancing comprehension in small reading groups using a manipulation strategy     

Arthur M. Glenberg  Megan Brown  Joel R. Levin 《Contemporary educational psychology》2007

Having young readers manipulate objects to correspond to the characters and actions in a text greatly enhances comprehension as measured by both recall and inference tests. As a step toward classroom implementation, we applied this manipulation strategy in small (three-child) reading groups. For successive critical sentences, one child would read the sentence aloud and then manipulate the objects, then the next child would read and manipulate, and so on. Children in a reread control condition also alternated reading the text. For the reread condition, one child would read the critical sentence and then reread it, followed by the next child, and so on. Children who manipulated were substantially more accurate in answering questions about the texts. Thus, the manipulation strategy meets at least some of the criteria for being applicable in a classroom setting, namely it is effective when applied in small groups.  相似文献   

The pedagogical benefits of enacting positive psychology practices through a student–faculty partnership approach to academic development     

Alison Cook-Sather  Joel Alden Schlosser  Abigail Sweeney  Laurel M. Peterson  Kimberly Wright Cassidy  Ana Colón García 《International Journal for Academic Development》2018,23(2):123-134

Academic development that supports the enactment of positive psychology practices through student–faculty pedagogical partnership can increase faculty confidence and capacity in their first year in a new institution. When student partners practice affirmation and encouragement of strengths-based growth, processes of faculty acclimation and self-authoring can be accelerated. This article presents a student–faculty pedagogical partnership program and positive psychology practices that focus on faculty strengths and capacities as the foundation for reinforcing and revising existing pedagogical strategies and for sustaining energy for continued development. It combines collaborative autoethnographic and comparative case study approaches to investigate the pedagogical benefits of these practices.  相似文献   

Alternative conceptions in animal classification: A cross-age study     

John E. Trowbridge  Joel J. Mintzes 《科学教学研究杂志》1988,25(7):547-571

Employing a cross-age design, this study examined students' alternative conceptions in animal classification at the elementary, secondary, and college levels. Based on a previous study that made use of clinical interviews and a classification task, subjects (N = 468) were administered a multiple-choice/free-response instrument that probed understanding of the concept animal, the vertebrate/invertebrate distinction, and the principal vertebrate classes. Results suggest that students subscribe to a highly restricted view of animals; applying the label almost exclusively to vertebrates, especially to common mammals. When asked to distinguish between vertebrate and invertebrate animals and to classify several species into vertebrate groups, a wide range of alternative conceptions emerged. Cross-age comparisons indicate that many of these alternative views remain intact throughout the school years, while others yield more readily to formal instruction and/or nonschool experiences. Considered within the context of a neoconstructivist view of learning, several suggestions are offered for teaching concepts in animal classification.  相似文献   

Tablet computers in Philippine public schools: school-level factors that influence technology management and use     

Jedaiah Joel Lumagbas  Wally Smith  Esther Care  Claire Scoular 《Technology, Pedagogy and Education》2019,28(1):73-89

Many developing countries are investing in large-scale initiatives to deploy information and communications technology in schools. However, merely equipping schools with hardware and software does not guarantee that the technology is used effectively to improve learning outcomes. This study aims to identify factors that influence the use of technology in schools in a developing-country context. It investigates this through a multiple-case study of the Australian AID tablet computer programme in the Philippines, in which 1000 tablets were given to nine public schools for student use. Focusing specifically on the impact at a whole-school level, the study revealed factors affecting outcomes that were specific to a developing-country context, as well as confirming the relevance of more general factors identified in the literature. The study also brings to light tablet-specific benefits and issues in this context. These results have implications for the effective school-level implementation of technology programmes in developing countries. Recommendations that proceed from these are presented for policy-makers and school administrators looking to use these devices in schools.  相似文献   

Psychopharmacological intervention. II: Teacher perceptions of psychotropic medication for students with learning disabilities     

M H Epstein  N N Singh  J Luebke  C E Stout 《Journal of learning disabilities》1991,24(8):477-483

The perceptions, knowledge, and opinions of 104 teachers of students with learning disabilities regarding medication used with their students were investigated. The students' doctors were perceived as the professionals primarily responsible for making the decision to have the student either placed on or taken off medication. The teachers indicated that global impressions and direct behavioral observations were used to assess the effects of medication but that they would prefer to use behavioral observations and rating scales. Hyperactivity and delusions/hallucinations were perceived as the problems most likely to lead to medication. Less than 15% of the teachers indicated that their professional preservice training had provided them with sufficient information on the use of medication for children with behavior problems, and less than 20% had a similar opinion regarding their inservice training on the same topic.  相似文献   

Neoliberalism,imperialism and conservatism: tangled logics of educational inequality in the global South     

Joel Windle 《Discourse: Studies in the Cultural Politics of Education》2019,40(2):191-202

ABSTRACT

Accounts of neoliberalism in education frequently evoke a universal trend, with insufficient attention to context, as well as routinely presenting the ‘pre-neoliberal’ as the ideal. This paper argues that studies of neoliberalism, concentrated in the global North, frequently ignore the distinctive forms and histories of neoliberalism in the global South, as well as its connections to other logics of power, which are illustrated using examples of schooling in Brazil. The differing weight of neoliberal politics and policies across geopolitical boundaries suggests caution in casting neoliberalism as a unique institutional setting for contemporary educational inequalities or attributing all educational conservatism to neoliberalism. A conceptual contribution is provided by proposing a multi-scalar approach to educational inequalities, in which educational sites, events and practices are considered in terms of nexus.  相似文献
