Welche Zusammenhänge bestehen zwischen dem fachspezifischen Professionswissen von Mathematiklehrkräften und ihrer Ausbildung sowie beruflichen Fortbildung?

Zusammenfassung Der vorliegende Beitrag besch?ftigt sich aus der Perspektive von Theorien zum Kompetenzerwerb mit dem Zusammenhang zwischen dem fachspezifischen Professionswissen von Mathematiklehrkr?ften und ihrer Ausbildung und beruflichen Fortbildung. Dabei wurden institutionelle Unterschiede der Lehramtsausbildung wie auch individuelle Unterschiede im Studienerfolg, der Berufserfahrung und der besuchten beruflichen Fortbildungen untersucht. Die Analysen basieren auf Daten von 195 Mathematiklehrkr?ften, die an der COACTIV-Studie teilnahmen. Unsere Ergebnisse zeigen, dass sich Lehrkr?fte unterschiedlicher Lehr?mter deutlich in ihrem professionellen Wissen unterscheiden und dass insbesondere der Erfolg im Studium mit besseren Leistungen im Fachwissen und im fachdidaktischen Wissen zusammen hing. Wir diskutieren Implikationen unserer Ergebnisse vor dem Hintergrund der Lehramtsausbildung und beruflicher Fortbildungen.      

AGE‐FAIR ASSESSMENT OF PSYCHOMETRIC INTELLIGENCE

This study examined the validity of a parallel form of the Primary Mental Abilities test for use with adults aged 50 to 90 years. Significant intraindividual performance gains on the parallel form were observed on the Verbal and Number subtests, while the effect on Space and Reasoning subtests was less substantial The development of such age‐fair measures of psychometric intelligence and related issues are discussed within the context of current developments in research on aging.     

互补性与次协调性

玻尔互补性原理的准确意义已引起了许多争论。这里我们并不打算对玻尔的观点进行详细的评论,而是对在一种明确的意义上包含互补性被我们称之为C-理论的理论所能理解的东西作尽可能有道理的解释。那些理论的基本逻辑是一种通过对经典逻辑的演绎概念作恰当修改而得到的所谓＂次经典＂逻辑。粗略地说,C-理论是含有＂物理上＂不相容定理（尤其是矛盾定理）的非平庸理论。因此,其基本逻辑是一种次协调逻辑。本文被视为我们有关C-理论及其应用的一系列作品的第一篇。     

Children with disabilities: a longitudinal study of child development and parent well-being.

This Monograph presents the results of the Early Intervention Collaborative Study, a longitudinal investigation of the cognitive and adaptive behavior development of children with developmental disabilities and the adaptation of their parents, extending from infancy through middle childhood. The study was designed to generate and test conceptual models of child and family development and contribute to the knowledge base that informs social policy and practice. The sample for the investigation reported here consists of 183 children with Down syndrome, motor impairment, developmental delay and their families who were recruited at the time of their enrollment in an early intervention program in Massachusetts or New Hampshire. Data were collected at five time points between entry to early intervention and the child's 10th birthday. Home visits were conducted at each time point and included child assessments, maternal interview, and questionnaires completed independently by both parents. Trajectories in children's development and parental well-being were analyzed using hierarchical linear modeling. Predictor variables were measured at age 3 years when children were exiting early intervention programs. Children's type of disability predicted trajectories of development in cognition, social skills, and daily living skills. Children's type of disability also predicted changes in maternal (but not paternal) child-related and parent-related stress. Beyond type of disability, child self-regulatory processes (notably behavior problems and mastery motivation) and one aspect of the family climate (notably mother-child interaction) were key predictors of change in both child outcomes and parent well-being. A different aspect of the family climate--family relations--also predicted change in child social skills. Parent assets, measured as social support and problem-focused coping, predicted change in maternal and paternal parent-related stress respectively. The implications of these findings for both the science of child development and the policies and practices of developmental intervention are discussed.     

The Effect of Early Intervention Services on Maternal Well-Being

In this investigation we examine the relation between intensity, duration, and comprehensiveness of early intervention (EI) services and changes in three aspects of maternal well-being: parenting stress, social support, and family cohesion. Data on the hours, length, and types of services received by a sample of 133 children and families from EI programs in Massachusetts and New Hampshire were gathered from the point of entry into EI to the point of discharge around the child's third birthday. Hierarchical regression analyses were used to determine which measure of EI service intervention contributed significantly to the explained variance in changes in maternal well-being, over and above aspects of the child's functioning and prior levels of maternal well-being. Results indicated that, although greater service intensity was associated with improved family cohesion overall, mothers of children without motor impairment reported greater increases than mothers of children with motor impairment. Service intensity and comprehensiveness predicted significant increases in social support levels. EI services did not have a significant impact on parenting stress. Three practice and policy implications are discussed: building flexibility into EI service provision to be responsive to individual family needs; attending to the accommodations required of families raising a child with a motor impairment; and incorporating other aspects of family functioning into future studies of EI effectiveness.     

亲爱的木木，我们开始认真了

春天总是过得异常快，刚下过几场雨。就已经快三月了。雨还在吧嗒吧嗒地下着，不过再也不用叫醒木木了。毕竟快高考了，谁还会再在课堂上睡觉呢？木木，也许再陪你听过几场雨，就会到那个绵长绵长的六月了吧？     

Family Influences on Adaptive Development in Young Children with Down Syndrome

In this study we investigated the extent to which the family environment predicted differences in trajectories of adaptive development in young children with Down syndrome. The sample was comprised of 54 children with Down syndrome and their families who were studied from infancy through the age of 5 years as part of a longitudinal study of children with disabilities. Hierarchical linear modeling (HLM) was used to estimate the parameters of hierarchical growth models in domains of adaptive development. Results indicated that growth in communication, daily living skills, and socialization domains were predicted by measures of the family environment (i.e., family cohesion and mother-child interaction) above and beyond that predicted by maternal education. Further, Bayley MDI measures during infancy did not predict changes in adaptive development in any of the domains. The results are discussed in terms of implications for service provision and for expanding theoretical frameworks to include the development of children with disabilities.
