THE ROLE OF TUTORING IN PROBLEM SOLVING^*

Abstract

THIS PAPER is concerned with the nature of the tutorial process; the means whereby an adult or "expert" helps somebody who is less adult or less expert. Though its aim is general, it is expressed in terms of a particular task: a tutor seeks to teach children aged 3, 4 and 5 yr to build a particular three-dimensional structure that requires a degree of skill that is initially beyond them. It is the usual type of tutoring situation in which one member "knows the answer" and the other does not, rather like a "practical" in which only the instructor "knows how". The changing interaction of tutor and children provide our data.A great deal of early problem solving by the developing child is of this order. Although from the earliest months of life he is a "natural" problem solver in his own right (e.g. Bruner, 1973) it is often the ease that his efforts are assisted and fostered by others who are more skilful than he is (Kaye, 1970). Whether he is learning the procedures that constitute the skills of attending, communicating, manipulating objects, locomoting, or, indeed, a more effective problem solving procedure itself, there are usually others in attendance who help him on his way. Tutorial interactions are, in short, a crucial feature of infancy and childhood. Our species, moreover, appears to be the only one in which any "intentional" tutoring goes on (Bruner, 1972;Hinde, 1971). For although it is true that many of the higher primate species learn by observation of their elders (Hamburg, 1968; van Lawick-Goodall, 1968), there is no evidence that those elders do anything to instruct their charges in the performance of the skill in question. What distinguishes man as a species is not only his capacity for learning, but for teaching as well. It is the main aim of this paper to examine some of the major implications of this interactive, instructional relationship between the developing child and his elders for the study of skill acquisition and problem solving.The acquisition of skill in the human child can be fruitfully conceived as a hierarchical program in which component skills are combined into "higher skills" by appropriate orchestration to meet new, more complex task requirements (Bruner, 1973). The process is analogous to problem solving in which mastery of "lower order" or constituent problems in a sine qua non for success with a larger jjroblcm, each level influencing the other-as with reading where the deciphering of words makes possible the deciphering of sentences, and sentences then aid in the deciphering of particular words (F. Smith, 1971). Given persistent intention in the young learner, given a "lexicon" of constituent skills, the crucial task is often one of com-

Towards a unified science of cultural evolution

“…Developmental psychologists have demonstrated high-fidelity imitation by subjects of the behaviour of a model, from Bandura's classic studies on aggression (e.g., Bandura et al 1961) through to comparative studies of observational learning in children and chimpanzees Nagell et al 1993;Whiten 1998;Whiten et al 1996;Whiten et al, in press), and the role of pedagogy in cultural transmission (Csibra & Gergely 2005;Gergely & Csibra 2006;Wood et al 1976). Other studies have tracked the transmission of text along linear chains of participants (Bangerter 2000;Kashima 2000;Mesoudi et al, 2006).…”

Dignité humaine et Pensée critique dialogique chez des enfants et des adolescents

“…Ainsi, nous avons observé que le processus de développement ou d'apprentissage d'une PCD s'effectue à la manière d'un « échafaudage » (Wood, Bruner & Ross, 1976), c'est-à-dire que la pensée s'approprie graduellement des représentations plus complexes, tout en conservant des ancrages dans les représentations plus simples, ces dernières disparaissant peu à peu, au fur et à mesure que la pensée se transforme et s'enrichit. En effet, nous avons observé que, dans chaque groupe d'élèves étudié, la perspective épistémologique dominante est précédée d'une perspective plus simple qui semble s'estomper, et suivie d'une perspective plus complexe qui semble en voie de construction (voir Daniel & Gagnon, 2016).…”

The discourse of a 'smart' technology: implications for educational practice

“…Observation of skilled tutors suggests a form of interaction 'management' that is more than simply strategic insertions of advice or reinforcement. Such narrow conceptions may be encouraged by the fashionable discourse of teachers being 'guides on the side' (King, 1993) -a view sometimes aligned with the social constructivism made popular through Vygotsky's (1933Vygotsky's ( /1978 writing and the scaffolding metaphor of Wood et al (1976). However, Vygotsky's own formulation of such an expert's scaffolded guidance was built more around notions of the expert's participation in a shared activity -rather than simply their ability to calculate and contribute timely hints or answers.…”
