A Galilean Approach to the Galileo Affair, 1609–2009

Galileo’s telescopic discoveries of 1609–1612 provided a crucial, although not conclusive, confirmation of the Copernican hypothesis of the earth’s motion. In Galileo’s approach, the Copernican Revolution required that the geokinetic hypothesis be supported not only with new theoretical arguments but also with new observational evidence; that it be not only supported constructively but also critically defended from objections; and that such objections be not only refuted but also appreciated in all their strength. However, Galileo’s defense of Copernicanism triggered a sequence of events that climaxed in 1633, when the Inquisition tried and condemned him as a suspected heretic. In turn, the repercussions of Galileo’s condemnation have been a defining theme of modern Western culture for the last four centuries. In particular, the 20th century witnessed a curious spectacle: rehabilitation efforts by the Catholic Church and anti-Galilean critiques by secular-minded left-leaning social critics. The controversy shows no signs of abating to date, as may be seen from the episode of Pope Benedict XVI’s attitude toward Paul Feyerabend’s critique of Galileo. Nevertheless, I have devised a framework which should pave the way for eventually resolving this controversy, and which is modeled on Galileo’s own approach to the Copernican Revolution.     

What If the Doors of Every Schoolhouse Opened to Social-Emotional Learning Tomorrow: Reflections on How to Feasibly Scale Up High-Quality SEL

Social-emotional learning (SEL) refers to a set of competencies that form the basis of human interaction. So, SEL in schools is no fad. But what would happen if every school actively wanted to bring in SEL tomorrow? Using the articles in the special issue on SEL as a springboard, this article looks at the neurological basis of SEL, SEL best practices, approaches to SEL instruction, assessment, and the complex issue of SEL and equity, and it reflects on the implications of these areas for scaling up sooner rather than later. Specific guidelines are provided, starting with this basic point: There are not enough experts available to guide this process, so schools must invest in staff learning about SEL, its rootedness in our biology, its basic role in accomplishing everything humans try to accomplish, and what we know about best practices and must provide cohort-based, ongoing professional development experiences that provide continuous support.     

The effects of changes in class size on teacher–pupil interaction

This chapter examines the changes in teacher–pupil interaction which occurred when teachers from the state maintained sector, with classes containing around thirty children, were provided with the opportunity to teach classes of approximately half that size. This was achieved either by “buddying” each of these teachers with a partner from a private school or by employing an extra teacher to take half of the large class. The results of the observation of these lessons showed increases in the types of interaction which previous research has shown to be positively correlated with increased pupil achievement. These increases, however, were not statistically significant. The chapter, therefore, concludes that before future experimental studies are carried out, there is a need for training designed to maximize the use of these key teacher–pupil interactions in small class settings.     

Solitary and Collaborative Pretense Play in Early Childhood: Sources of Individual Variation in the Development of Representational Competence

This study evaluates sources of individual variation in child pretense play as an expression of emerging mental representation. Family sociodemographic characteristics, maternal personological characteristics, and maternal affective and cognitive play behaviors, as well as children's gender, language competence, and play, were examined simultaneously. Naturalistic child solitary play and child collaborative play with mother were videorecorded in 141 20–month-olds. Child solitary play, child-initiated and mother-initiated collaborative play with mother, and maternal demonstrations and solicitations of play were then coded into nonsymbolic and symbolic acts. Zero-order relations obtained between child play and, respectively, child gender and language, family SES, and maternal verbal intelligence, personality, physical affection, and play demonstrations and solicitations. Structural equation modeling supported the following unique predictive relations: Child language and mothers' symbolic play positively influenced child collaborative play, and child gender and mothers' verbal intelligence predicted child solitary play. Child gender and mothers' verbal intelligence and physical affection influenced mothers' play and so influenced child collaborative play indirectly. The cognitive advantages of child play and maternal influences on child play are placed in an adaptive parenting framework.     

Emotional Determinants of Infant-Mother Attachment

The present study examined the assumption that emotion-related characteristics of mothers and infants contribute to the development of infant-mother attachment in the first year of life. Mothers' emotion and personality characteristics were assessed with expressive-behavior ratings and self-report scales. Infant characteristics were measured by emotion and temperament questionnaires (mother report) and objective coding of facial expressions of emotions. Attachment classifications were determined by means of the Strange Situation procedure, and a continuous-variable index of attachment security was derived by a discriminant function procedure. Mothers' emotion experiences, expressive behaviors, and personality traits were significant predictors of the level of security of the infant-mother attachment. Infants' expressive and temperamental characteristics as rated by their mothers were also significant predictors of attachment security.
