Some determinants of second-order conditioning

In a Pavlovian conditioning situation, an initially neutral stimulus may be made excitatory by nonreinforced presentations in compound with an established conditioned excitor [i.e., second-order conditioning (SOC)]. The established excitor may be either a punctate cue or the training context. In four conditioned suppression experiments using rats, we investigated whether SOC phenomena parallel other cue interaction effects. In Experiment 1, we found that the response potential of a target stimulus was directly related to the intertrial interval when SOC was mediated by a punctate cue, and inversely related to the intertrial interval when SOC was mediated by the training context. Experiment 2 demonstrated that punctate- and context-mediated SOC are oppositely affected by posttraining context extinction, and Experiments 3 and 4 demonstrated that context- and punctate-mediated SOC are differentially affected by conditioned stimulus (Experiment 3) and unconditioned stimulus (Experiment 4) preexposure treatments. These findings parallel phenomena in conditioned inhibition and cue competition situations.     

Effects of reinforcer delay and variability in a successive-encounters procedure

Pigeons responded in a successive-encounters procedure that consisted of a search period, a choice period, and a handling period. The search period was either a fixed-interval or a mixed-interval schedule presented on the center key of a three-key chamber. Upon completion of the search period, the center key was turned off and the two side keys were lit. A pigeon could either accept a delay followed by food (by pecking the right key) or reject this option and return to the search period (by pecking the left key). During the choice period, a red right key represented the long alternative (a long handling delay followed by food), and a green right key represented the short alternative (a short handling delay followed by food). The experiment consisted of a series of comparisons for which optimal diet theory predicted no changes in preference for the long alternative (because the overall rates of reinforcement were unchanged), whereas the hyperbolic-decay model predicted changes in preference (because the delays to the next possible reinforcer were varied). In all comparisons, the results supported the predictions of the hyperbolic-decay model, which states that the value of a reinforcer is inversely related to the delay between a choice response and reinforcer delivery.     

Logics,rhetoric and ‘the blob’: Populist logic in the Conservative reforms to English schooling

A lot has been written about the lasting implications of the Conservative reforms to English schooling, particularly changes made by Michael Gove as Education Secretary (2010–2014). There is a lot less work, however, on studying the role that language, strategy and the broader political framework played in the process of instituting and winning consent for these reforms. Studying these factors is important for ensuring that any changes to education and schooling are not read in isolation from their political context. Speeches particularly capture moments where intellectual and strategic political traditions meet, helping us to form a richer understanding of the motives behind specific reform goals and where they fit into a political landscape. This article analyses speeches and policy documents from prominent politicians who led the Conservative education agenda between 2010–2014 to illustrate how politicians mobilised a deliberate populist strategy and argumentation to achieve specific educational goals, but which have had broader social and political implications. Concepts from interpretive political studies are used to develop a case analysis of changes to teacher training provision and curriculum reform, illustrating how politicians constructed a frontier between ‘the people’ (commonly teachers or parents) and an illegitimate ‘elite’ (an educational establishment) that opposed change. This anti-elite populist rhetoric, arguably first tested in the Department for Education, has now become instituted more widely in our current British politics.     

A science need: Designing tasks to engage students in modeling complex data

In this information age, the capacity to perceive structure in data, model that structure, and make decisions regarding its implications is rapidly becoming the most important of the quantitative literacy skills. We build on Kaput’s belief in a Science of Need to motivate and direct the development of tasks and tools for engaging students in reasoning about data. A Science of Need embodies the utility value of mathematics, and engages students in seeing the importance of mathematics in both their current and their future lives. An extended example of the design of tasks that require students to generate, test, and revise models of complex data is used to illustrate the ways in which attention to the contributions of students can aid in the development of both useful and theoretically coherent models of mathematical understanding by researchers. Tools such as Fathom are shown as democratizing agents in making data modeling more expressive and intimate, aiding in the development of deeper and more applicable mathematical understanding.

Digital Rhetoric: Toward an Integrated Theory

This article surveys the literature on digital rhetoric, which encompasses a wide range of issues, including novel strategies of self-expression and collaboration, the characteristics, affordances, and constraints of the new digital media, and the formation of identities and communities in digital spaces. It notes the current disparate nature of the field and calls for an integrated theory of digital rhetoric that charts new directions for rhetorical studies in general and the rhetoric of science and technology in particular.     

Supporting Teaching Faculty as Scholars: A Developmental Model

Professors from across the academic disciplines at Council for Christian College & Universities (CCCU) institutions have traditionally excelled in their teaching. In recent years, CCCU faculty have also increasingly been expected to conduct research and to publish scholarly work. As CCCU institutions expand research and scholarship expectations for faculty, we must also provide the requisite support for professors to be effective in this work. In this article, we highlight institutional practices to encourage, support, and celebrate scholarly writing and research by faculty. Drawing upon findings from Zuidema's 2016 survey of CCCU chief academic officers, we offer benchmark practices for communicating expectations, offering tangible supports and resources, augmenting accountability measures with formative feedback, and recognizing and celebrating scholarship. Against this backdrop, we highlight practical, affordable strategies used at Point Loma Nazarene University (PLNU) in California and Dordt College in Iowa, two CCCU institutions that have increased expectations for scholarship in recent years. Through these illustrations, we aim to inspire new and creative strategies for supporting scholarship by showing how these practices are an outgrowth of a developmental philosophy of leadership that seeks to invest in the core resource of CCCU institutions: the faculty.     

A developmental review of response time data that support a cognitive components model of reading

The present article provides a review of numerous studies that measured response times for cognitive tasks related to six components of the reading process. The component processes were single-letter recognition, multi-letter unit identification, word and pseudoword identification, semantic access/concept activation, phrase and sentence comprehension, and text comprehension. The response time data are presented in tables and summarized in the text. The data provide support for a componential view of reading.     

Social IEP Objectives, Teacher Talk, and Peer Interaction in Inclusive and Segregated Preschool Settings

The purpose of this study was to examine: (a) the role of teacher talk in promoting peer interaction, (b) the adequacy of social IEP objectives to reflect children’s social functioning and guide provision of teacher talk, and (c) differences in children’s peer interaction and teacher talk in inclusive and segregated settings. Thirty children with disabilities and their teachers participated. Overall, we observed low rates of teacher talk thought to support peer interaction; however, when teachers verbally facilitated peer interaction, children were observed interacting more frequently with peers. Children’s social IEPs accurately reflected their current level of social functioning. However, the social IEPs appeared to fail to influence teacher intervention. Finally, children with disabilities in inclusive settings interacted with peers more than children in segregated settings, even though there was no significant difference in amount of teacher talk in the two settings.
