Mastery Motivation: Definition and Measurement

This paper presents a working definition of mastery motivation which has evolved from our research with infants and young children over the past two decades. We define mastery motivation as a psychological force that stimulates an individual to attempt independently, in a focused and persistent manner, to solve a problem or master a skill or task which is at least moderately challenging for him or her. After describing key features of this definition, we discuss three conceptual issues: 1) the distinction between mastery motivation and cognitive competence, 2) developmental transitions in mastery motivation, and 3) the breadth of the concept. The paper concludes with a long section on assessing mastery motivation. Persistence at tasks is the main measure of the strength of the child's mastery motivation. Our structured task procedure, for 15- to 36-month-old children, attempts to disentangle mastery motivation and competence. We have also developed a questionnaire to assess mastery motivation in general and in five specific behavioral domains: social, symbolic, combinatorial, means-end, and gross motor. We believe that our definition helps to clarify the concept of mastery motivation and that our assessment procedures will facilitate future research.     

No Difference in the Neural Underpinnings of Number and Letter Copying in Children: Bayesian Analysis of Functional Near‐Infrared Spectroscopy Data

It is under debate whether the neural representation of numbers and letters might rely on distinct neural correlates, or on a mostly shared neural network. In the present study, a total of 47 children in fifth grade (Experiment 1) and sixth grade (Experiment 2) simply copied numbers and letters on a touch screen while brain activation changes were recorded by means of functional near‐infrared spectroscopy (fNIRS). fNIRS data of both experiments and a joint analysis revealed that a shared neural network, particularly in the left hemisphere, was activated in response to both number and letter copying. Interestingly, no difference was observed in brain activation patterns between these two stimuli, as revealed by Bayesian analysis. Our findings indicate that both number and letter copying lead to similar brain activation in children. We further suggest methodological and applied applications of these findings in the frame of educational neuroscience.     

Measuring perceived social support: Development of the child and adolescent social support scale (CASSS)

The measurement of students' social support has become a popular topic in education and psychology, yet measurement tools in this area are limited. In this study, we use a large, representative sample to conduct confirmatory factor, reliability, and correlational analyses of scores on the Child and Adolescent Social Support Scale (CASSS; Malecki, Demaray, Elliott, & Nolten, 1999). These analyses revealed evidence of reliability, a four‐factor structure (Parent, Teacher, Classmate, and Close Friend subscales), and construct validity. The results of this study indicate that the CASSS covaries as predicted with the clinically important constructs of self‐concept, social skills, and behavioral indicators. There is evidence that the CASSS can be used to understand children and adolescents' perceived social support. © 2002 John Wiley & Sons, Inc.     

Children, play, and computers in pre-school education

The paper reports a study designed to inform the development of an information and communication technology strategy for the pre‐school years of education. The main methods of collecting evidence were observations at seven pre‐school settings and interviews with at least two practitioners and a number of children at each site. Practitioners generally referred to children “playing with the computer”. We describe some of the problems to be found in the emphasis on free play in nurseries and play groups when this means children are using computers as complete novices. There were few examples of peer support; adults rarely intervened or offered guidance and the most common form of intervention was reactive supervision. Interaction with a computer was therefore a limited experience for most children, but we provide examples of guided interaction that suggest a way forward for professional development.
