Associative foundation of causal learning in rats

Are humans unique in their ability to interpret exogenous events as causes? We addressed this question by observing the behavior of rats for indications of causal learning. Within an operant motor–sensory preconditioning paradigm, associative surgical techniques revealed that rats attempted to control an outcome (i.e., a potential effect) by manipulating a potential exogenous cause (i.e., an intervention). Rats were able to generate an innocuous auditory stimulus. This stimulus was then paired with an aversive stimulus. The animals subsequently avoided potential generation of the predictive cue, but not if the aversive stimulus was subsequently devalued or the predictive cue was extinguished (Exp. 1). In Experiment 2, we demonstrated that the aversive stimulus we used was in fact aversive, that it was subject to devaluation, that the cue–aversive stimulus pairings did make the cue a conditioned stimulus, and that the cue was subject to extinction. In Experiments 3 and 4, we established that the decrease in leverpressing observed in Experiment 1 was goal-directed instrumental behavior rather than purely a product of Pavlovian conditioning. To the extent that interventions suggest causal reasoning, it appears that causal reasoning can be based on associations between contiguous exogenous events. Thus, contiguity appears capable of establishing causal relationships between exogenous events. Our results challenge the widely held view that causal learning is uniquely human, and suggest that causal learning is explicable in an associative framework.

Student evaluation of courses: what predicts satisfaction?

The main goals of course evaluations are to obtain student feedback regarding courses and teaching for improvement purposes and to provide a defined and practical process to ensure that actions are taken to improve courses and teaching. Of the items on course evaluation forms, the one that receives the most attention and consequently the most weight is the question, ‘Overall, I was satisfied with the quality of this course.’ However, no attention has been placed on examining the predictors of students being ‘satisfied with the quality of this course’ overall. This study attempts to address this gap. The findings show that while student characteristics and reasons for enrolling in a course are predictors of overall satisfaction, it is the evaluation questions that predict the majority of the variation in course satisfaction. The findings also reveal that faculty‐selected optional questions are stronger predictors of overall satisfaction than compulsory questions.     

Leg preference and interlateral asymmetry of balance stability in soccer players

To examine the effect of long lasting practice on pedal behavior in sport, we compared experienced adult soccer players and nonsoccer players on leg preference in motor tasks requiring general mobilization, soccer related mobilization, and body balance stabilization. We also evaluated performance asymmetry between the right and left legs in static and dynamic unipedal body balance, based on center of pressure displacement, and correlated that with leg preference in balance stabilization tasks. Results revealed (a) a distinct leg preference between mobilization and stabilization tasks, which were significantly different between players and nonplayers, (b) similar balance stability between the right and left legs, (c) greater stability of experienced players compared with nonplayers in static and dynamic balance, and (d) absence of a significant leg preference correlation with interlateral balance asymmetry. These results suggest an effect of extensive soccer skill practice on establishing leg preference for specific mobilization tasks and overall balance control.     

Black-white achievement gap and family wealth.

This article examines the extent to which family wealth affects the Black-White test score gap for young children based on data from the Panel Study of Income Dynamics (aged 3-12). This study found little evidence that wealth mediated the Black-White test scores gaps, which were eliminated when child and family demographic covariates were held constant. However, family wealth had a stronger association with cognitive achievement of school-aged children than that of preschoolers and a stronger association with school-aged children's math than on their reading scores. Liquid assets, particularly holdings in stocks or mutual funds, were positively associated with school-aged children's test scores. Family wealth was associated with a higher quality home environment, better parenting behavior, and children's private school attendance.     

Neither Right nor Wrong: How a Teacher Integrates Her Personal and Professional Life With Policy

This article focuses on the importance of recognizing and appreciating the ways that a teacher integrates her personal and professional life with an English-only policy. Much can be learned from the ways in which she negotiates social forces and integrates them into her individual reality while making sense of the restrictive language policy. Whether they are consciously aware of it or not, teachers have the power to make ethico-political choices. Motivated by moral principles and personal beliefs, teachers make decisions about their right or ability to determine and follow a particular course of action that a policy may dictate. Educational policies coming from the top-down can be daunting and leave teachers with a sense of a loss of control and power over what happens in their classrooms. However, I argue that teachers do have control over how they interpret the policy. There is no clear right or wrong path, but rather a multitude of diverse choices that are available to teachers.     

Toward Sustainable Educational Changes through School-Based Professional Development on ELL Assessment for New Teachers

Developing teachers' knowledge about assessing English language learners (ELLs) is critical for achieving intended policy outcomes of improving teaching under Race to the Top policy and Common Core State Standards. In addition to teachers' expressed concerns about teaching Common Core State Standards to ELLs in a national survey published in Education Week (Gewertz, 2013 Gewertz, C. (2013, February). Standards worrying teachers. Education Week, 32(22), 12–13. [Google Scholar]), the formation of two assessment consortiums (i.e., Smarter Balanced Assessment Consortium, or SBAC, and Partnership for Assessment of Readiness for College and Careers, or PARCC) indicates the urgency for teachers to demonstrate their assessment knowledge and for schools to provide meaningful professional development opportunities in that area. In this article, we detail the rationale for school-based professional development targeting assessment, especially for new teachers, and outline a proposed procedure for providing such training.     

Dose–response relations between preschool teachers’ exposure to components of professional development and increases in quality of their interactions with children

The present study examined the pattern of associations over time between the quality of observed interactions and exposure to features of an effective coaching model for 170 preschool teachers enrolled in a study investigating professional development impacts. Using a treatment-on-the-treated approach, teachers exposed to a greater number of cycles of coaching showed more improvement in classroom interactions over the year. More specifically, of the two components of treatment examined, video exemplars and individual coaching prompts, exposure to prompts was associated with growth from baseline in instructionally supportive interactions while watching video exemplars was associated with growth in emotionally supportive behaviors in analysis of linear effects. Watching emotional support video exemplars was negatively associated with growth in classroom organization behaviors. The non-linear pattern of these associations suggested that the initial dosage of prompts created observable effects on instructional support, but after a certain point additional dosage was not effective. Conversely, initial dosage did not create observable effects on emotional support, but improvement was observed after exposure to a certain minimum dosage of time watching video exemplars. The results have implications for the design, delivery, and focus of professional development for early childhood educators.
