What resources do parents exchange in the VCLL?

Abstract

When parent relationships form within the context of a youth baseball league, they can and often do facilitate the exchange of benefits to one or more parties, a phenomenon known as social capital. Based on 18 months of fieldwork, approximately 30 interviews, and innumerable casual conversations with parents and league officials, I explore the specific types of resources that were typically shared between parents of a youth baseball league in the American Southwest. I uncovered four specific types of benefits that parents offered and accepted as a result of the relationships they cultivated during baseball seasons: emotional support, information sharing regarding goods and services about town, job information sharing, and childcare.     

Professionalism in medical education

Medical professionalism in today's society requires the exhibition of a range of qualities deployed in the service of patients, rather than more traditionally defined aspects such as mastery, autonomy and self-regulation. These qualities incorporate demonstrated clinical competence; aspiring to excellence in practice while demonstrating humility and recognition of personal limitations; exercising professional judgement; and maintaining a fiduciary relationship with patients by the earning and maintenance of trust.     

Estimating Causal Effects of Education Interventions Using a Two-Rating Regression Discontinuity Design: Lessons From a Simulation Study and an Application

A valuable extension of the single-rating regression discontinuity design (RDD) is a multiple-rating RDD (MRRDD). To date, four main methods have been used to estimate average treatment effects at the multiple treatment frontiers of an MRRDD: the “surface” method, the “frontier” method, the “binding-score” method, and the “fuzzy instrumental variables” method. This article uses a series of simulations to evaluate the relative performance of each of these four methods under a variety of different data-generating models. Focusing on a two-rating RDD (2RRDD), we compare the methods in terms of their bias, precision, and mean squared error when implemented as they most likely would be in practice—using optimal bandwidth selection. We also apply the lessons learned from the simulations to a real-world example that uses data from a study of an English learner reclassification policy. Overall, this article makes valuable contributions to the literature on MRRDDs in that it makes concrete recommendations for choosing among MRRDD estimation methods, for implementing any chosen method using local linear regression, and for providing accurate statistical inferences.     

Sex and Risk: Parental Messages and Associated Safety/Risk Behavior of Adult Children

The importance of both parent–child conversations about sex and general family communication climates has been emphasized in numerous studies. This study compared general family communication via family communication patterns (FCP) to specific parental communication about sex in understanding young adults’ sexual communication/risk (avoidance, threat, and risk behavior). Results suggest that FCP were stronger predictors of adult children’s perceptions of sexual communication as threatening and overall avoidance of sexual communication with their partners compared to the frequency of and overall quality of parent–child conversations about sex. Theoretical and practical implications of these findings are also discussed.     

‘Crossing’ the equals sign: insights into pre-service teachers’ understanding of linear equations

This paper reports on an exploratory study designed to determine and enhance the conceptual understanding of a group of pre-service mathematics teachers at one Irish university utilizing an established framework for understanding mathematics. 23 students on a one year Professional Diploma in Mathematics Education participated in the study, which involved the distribution of a pre- and post-test and engagement in a ten week intervention designed to enhance their subject matter knowledge (SMK) and pedagogical content knowledge (PCK). The findings highlight that although there was an improvement in overall conceptual understanding across the entire cohort at the end of the intervention, within certain mathematical topics there was a statistically insignificant improvement and many deep-rooted issues remain. In this paper we focus on the pre-service teachers’ understanding of elementary algebra, in particular, how to solve a linear equation.     

Quantifying the long-term impact of zoological education: a study of learning in a zoo and an aquarium

Abstract

There is increasing evidence that zoos and aquariums do, as intended, educate their visitors. However, even though most zoos offer a wide array of educational experiences, few studies have considered if the duration of an educational experience affects learning or whether learning lasts beyond the immediate visit. The current study used matched-pairs surveys to investigate children’s knowledge, attitude and knowledge of positive behavior during both a five-day zoo camp and six months after an aquarium visit. The participants of the study included children aged 9–12?years some of whom had participated in a purposefully designed educational intervention. First, the impact of a five-day zoo camp experience on children’s learning was investigated. Second, learning retention was investigated six months after a school tour at an aquarium. Results showed that during the camp learning was positively affected by participation in the educational intervention and by previous zoo experience. Girls were more likely than boys to have an increase in learning six months after an aquarium visit. The study demonstrates that learning persists, but that education can be enhanced with longer programs. Thus, zoos can play an increasingly important role in igniting pro-environmental behavior.     

Metasearch accuracy for letters and symbols: do our intuitions match empirical reality?

The “familiarity effect” (Shen and Reingold, Perception & Psychophysics 63(3):464–475, 2001) is a phenomenon in which unfamiliar symbols perceptually “pop-out” when placed among familiar symbols (e.g., letters). In contrast, searching for familiar symbols among unfamiliar symbols is more challenging. Failure to account for effects such as these when predicting search performance could lead to overconfidence and error. This study investigated metacognitive awareness of the familiarity effect by asking participants to rate the speed and accuracy of search before they searched for either letter or symbol targets among letter or symbol distractors. Feature overlap between target and distractor and target presence or absence were also manipulated to provide concurrent cues to task difficulty. This study examined metacognitive awareness of the “familiarity effect,” and extended the findings from an earlier metasearch study (Redford et al., Memory and Cognition 39:1534–1545, 2011). Metacognition was accurate with respect to the familiarity effect. However, participants incorrectly predicted that they would detect a target’s absence faster than its presence. These findings suggest that people have metacognitive awareness for some aspects of visual search, even when patterns of search performance are complex and potentially counterintuitive. However, limitations exist in our metacognitive awareness of visual search. The results are discussed in relation to Koriat’s cue utilization framework and heuristic-based metacognition.     

Evidence-based teaching: a simple view of “science”

ABSTRACT

This paper examines the insistent claims by advocates of evidence-based teaching that it is a rigorous scientific approach. The paper questions the view that randomised controlled trials and meta-analyses are the only truly scientific methods in educational research. It suggests these claims are often based on a rhetorical appeal which relies on too simple a notion of “science”. Exploring the tacit assumptions behind “evidence-based teaching”, the paper identifies an empiricist and reductionist philosophy of science, and a failure to recognise the complexity of education and pedagogy. Following a discussion of large-scale syntheses of evidence (Hattie’s Visible Learning; the Education Endowment Foundation’s Teaching and Learning Toolkit), it examines in detail one strand of the latter concerning sports participation, which is used to illustrate flaws in procedures and the failure to take seriously the need for causal explanations.
