Peer education: The untapped potential

The purpose of this paper is to provide a rationale for making broader educational use of peer learning principles as explicated in developmental theory and research. The paper argues that peer learning brings with it unique motivational and cognitive benefits for participating peers. Research has shown that peer learning can bolster children's self-esteem, awaken their interest in challenging tasks, enhance scholarly achievement, and foster prosocial behavior. In particular, it is an effective means of enabling children to grasp basic concepts that underlie school curricula.Two different forms of peer learning, “peer tutoring” and “peer collaboration,” are distinguished. Each has its potential use: peer tutoring for transmitting information and drilling special skills; peer collaboration for facilitating intellectual discovery and the acquisition of basic knowledge.Some general guidelines for the integration of peer tutoring and peer collaboration in the classroom are offered. It is recognized that specific curriculum plans implementing these guidelines must be formulated with a view to the overall cultural context of the school system. Such plans must be molded in context to suit the needs of each particular site. It is concluded, however, that the general principles of peer education set forth in this position paper would enhance all varieties of schooling. As explicated in this article, peer education complements rather than supplants adult teaching, freeing up teachers' time and attention and enabling them to focus more directly and effectively on individual children's learning needs.     

Children's relative number judgments: One-to-one correspondence,recognition of noncorrespondence,and the influence of cue conflict

Although one-to-one correspondence can be seen as a component of successful counting, number conservation, and relative number judgments, there is evidence of considerable discrepancies between children's competencies in these different tasks. Concerning relative number judgments there are strikingly different claims concerning the ability of young children to make one-to-one correspondence-based judgments. In part these discrepancies reflect differences in criteria. Four experiments are reported in which 5-year-olds' relative number judgments of small and large number displays with and without perceptual aids were studied. Children were found to respond to local rather than global density differences and to benefit from the provision of perceptual aids on both small and large number displays with one exception, namely, large number displays where the longer row is less numerous.     

The selective impact of question form and input mode on the symbolic distance effect in children

Five experiments are reported on the symbolic distance effect (SDE) and related phenomena with 6- and 9-year-old children. In the first of these, children were asked to judge the relative sizes of animals in verbal and pictorial tests featuring the comparatives "bigger" and "smaller." A perceptual condition with actual objects was included by way of comparison. A Symbolic Distance Effect was obtained for both lexical and pictorial input. Mode differences were also observed. Pictures produced faster responses than words, and congruity effects occurred only in the pictorial condition. Although performance was similar in tests with either comparative, our subsequent experiments on both 6- and 9-year-olds reveal a significant asymmetry in the child's capacity to verify statements of relation as a function of the direction along the (size) continuum implied by the question. However, important differences between age groups also apparent in the data lead us to conclude that the older subjects develop strategies to overcome this asymmetry by translating certain statements of relation into a form more congruent with their natural modes of encoding.     

Attitudes toward the unconscious

As a keynote to a conference bringing together psychoanalysts and analytical psychologists, this paper addresses different mythic attitudes toward the unconscious, Starting with the caricatures of Oedipus and Narcissus that the author feels Jung and Freud originally projected onto each Other in the course of their quarrel. He moves on to the fairytale-like stories of Perseus and Beauty and the Beast to discover mote complex images of the stance taken in relation to the unconscious by present-day analysts: working within both die Jungian and the Freudian traditions.     

Organizational factors and work involvement

The aim of this paper is to describe a study which investigated the influence of organizational factors on job involvement and specialization involvement. It was hypothesized that rank, self-expression, participation in decision making, and career factors affect job and specialization involvement. The independent variables were chosen by considering an extension of Schein's (1971, Journal of Applied Behavioral Science, 7, 401–426) “career cone” concept. The hypotheses were tested using a sample of Australian Army officers (N = 384) in a questionnaire survey. The results showed that job involvement is associated primarily with self-expression, although the latter is influenced in turn by participation in decision making, and that specialization involvement is associated with both self-expression and career factors. Rank does not affect either involvement variable. It was concluded that Schein's concept is a useful guide to theory and research on career attitudes. The results support the proposition that job and specialization involvement are distinct constructs. Implications for organizations are discussed.     

A signal detection framework for the evaluation of probabilistic forecasts

In this paper I formulate an approach for evaluating probabilistic forecasts in terms of signal detection theory. Signal detection theory provides a powerful perspective for this type of problem, and a rich empirical background including methodological tools as well as an extensive body of research in many domains. I propose procedures which emphasize the maximization of expected utility for the decision maker who uses the forecasts. Further, I suggest approaches to obtaining indices of calibration and resolution within this framework. I also present arguments that the proposed indices will exhibit the same basic properties as do decompositions of Brier's (1950, Monthly Weather Review, 78, 1–3) mean probability score. However, the properties may be reflected in different ways, and hence, the present methods may lead to different conclusions about forecasting ability. Finally, I argue that the use of an expected utility loss function makes this approach more appropriate for practical applications as well as for theoretical research than other procedures with more arbitrary loss functions.     

Development of natural language concepts: IV. The relationship between semantic organization and learning

In Experiment 1, 30 subjects at each of three age levels were shown pictures of unfamiliar “animals”. They were told two semantic attributes for each animal (e.g., kind and strong) and were asked to learn these sets so that, when shown a picture, the appropriate attributes could be recalled. The results indicated that the dimensional structure of the attributes had a strong effect on new learning for young children. Incongruent pairs of attributes (e.g., kind and ugly) were difficult to learn compared to congruent (e.g., kind and beautiful) or unrelated (e.g., kind and tall) sets. These results indicate: (a) Attribute structure is a factor in new learning; (b) 6-year-olds tend to organize the verbal labels for attributes into bipolar dimensions, rather than into independent clusters of attributes. The latter findings require reexamination of the meaning of previous word-association data which had been interpreted as indicating that 6-year-olds tend not to organize meanings bipolarly. Experiment 2 showed that the disruptive effects of incongruence on new learning disappears by college age.     

Training children's self-control: A field experiment in self-monitoring and goal-setting in the classroom

A field experiment investigated the effects of training in self-monitoring and goal-setting skills on classroom study behavior and academic achievement among elementary school students in an individualized mathematics program. In the Self-Monitoring Conditions, students were shown a simple system for observing and maintaining daily records of their own study behavior during their math classes; orthogonally, in the Goal-Setting Conditions, students were shown a simple method of setting and recording daily performance goals during their math classes. Exposure to self-monitoring procedures produced significant increases in both appropriate study behavior and in actual achievement in the mathematics program, while exposure to goal-setting procedures had no effect on either study behavior or academic achievement. Nor, contrary to expectation, did exposure to the goal-setting instructions enhance the effectiveness of the self-monitoring system. The implications of these results in terms of implicit and explicit models of self-reinforcement processes were discussed.     

Transfer of compounds and components in the discriminative learning of retardates

The discriminative learning and transfer of compound and component problems were assessed in retarded subjects at two levels of intelligence. It was found that brighter subjects (MA = 10 years) found the component problems relatively easier than the compound problems to a greater extent than did the less developed subjects (MA = 5 years). The learning of compound solutions was shown to transfer positively to other compound problems and negatively to component problems. Component solutions were found to transfer positively to other component solutions and negatively to compound solutions. These dimensional transfer effects were interpreted to mean that both compound and component solutions were mediated and conceptual in nature. The developmental differences in relative usages of compound and component aspects of stimuli were viewed as the result of differences in direction of attention rather than of differences in complexity of processing.
