决不言“小”

这些运动员证明,并非只有个子高才会表现出色。你是否曾经因为个子矮小而经历过困难的时光?这种情况时常会发生在运动场上。在很多运动项目中,教练和观众们往往认为你长得     

Distinguishing Two Stages of Mathematics Conceptual Learning

In this theoretical article, we distinguish two stages of learning a new mathematical concept – participatory and anticipatory. We use a recently developed mechanism for explaining mathematical conceptual learning – reflection on activity-effect relationship – as well as von Glasersfelds tripartite model of a scheme, to explain qualitative distinctions between the two stages. We use this distinction to explain why instructional interventions (including inquiry-based approaches) may not bring about the intended instructional goals.     

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.     

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。     

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.     

Finding the skills for tomorrow: Information literacy and museum information professionals

This paper presents results from 21 semi-structured interviews with museum information professionals who were asked about their experiences working with information resources, tools, and technologies in museums. The interviews were analyzed to develop an understanding of the information literacy skills of museum information professionals. This paper presents the results of this analysis, and discusses the state of information literacy in museums, and the increasing need for museum information professionals to possess information literacy skills. The results illustrate how information literacy is defined by information professionals in museums, and how perceptions of information literacy and its importance to museums have changed over time.
