We discuss an emerging program of research on a particular aspect of mathematics learning, students' learning through their own mathematical activity as they engage in particular mathematical tasks. Prior research in mathematics education has characterized learning trajectories of students by specifying a series of conceptual steps through which…

This article presents what is possibly the first English translation of a 1930 manuscript related to Vygotsky's work (probably written by Vygotsky himself). This manuscript, the Zalkind Summary, is a five-point summary of his presentation to the First All-Union Congress on the Study of Human Behaviour in Leningrad in January 1930. This article…

Two studies, an experimental category learning task and a computational simulation, examined how sequencing training instances to maximize comparison and memory affects category learning. In Study 1, 2-year-old children learned color categories with three training conditions that varied in how categories were distributed throughout training and…

In a previous study, Parisse suggested that subject dislocations in French language (e.g. "la fille "elle" dort") could be considered as a marker of morphosyntactic development in children with normal language development. The present study aimed to develop this proposition and to confirm it with experimental data, more…

Discusses the dyslexic as having problems in translating concrete perceptions inherent in the spoken word to static and abstract representations of the printed page. Sequencing also offers a major challenge for the dyslexic. Improved understanding of the disturbance may lead to new treatment procedures. (CJ)

The first section of this paper deals with the question of whether Piaget is a developmental or a learning theorist; the second section relates Piaget's research findings and developmental theory to a sequence of curriculum units in mathematics. It is suggested that Piaget makes no distinction between learning and development of cognitive…

The criterion problem in the neoPiagetian cognitive-developmental literature is reviewed. This problem has provoked debate in the context of three empirical questions: concept age norms, concept training effects, and concept invariant sequences. It is argued that only the question of invaniant sequences in same-stage concepts is theoretically…

Defines five levels between concrete and formal operation in the development of the concept of controlling variables. The sample, methodology and research on which the work is based is described in SE 519 500. (CP)

This study tested certain implied predictions regarding conceptual learning at each of four sequential levels of development: concrete level, identity level, classificatory level, and formal level. For this purpose, scaled batteries to assess the level of conceptual development of children, kindergarten through high school, were constructed and a…

TO IMPROVE THE DEVELOPMENTAL RATE OF CULTURALLY DEPRIVED CHILDREN, A PRESCHOOL PROGRAM WAS OFFERED WHICH CONSISTED OF A PLANNED SEQUENCE OF ENVIRONMENTAL STIMULATION BASED ON THE THEORY THAT COGNITIVE DEVELOPMENT PROCEEDS THROUGH MOTOR-PERCEPTUAL-SYMBOLIC PHASES. SEVENTY-TWO DISADVANTAGED CHILDREN WERE DIVIDED INTO THREE MATCHED GROUPS. GROUP A…

This curriculum was designed as a learning sequence for the adults in charge of a group care center for infants. For example, the sequence of the steps in the child's motor development (e.g., reaching) are described, and some activities and materials appropriate to each step are suggested. Other areas for developmental sequences and activities…

Reviews theoretical frameworks and psychological processes underlying the perception and cognition of musical understanding. Suggests unifying ideas and processes based on a developmental learning framework applied to teaching methods and curriculum. Supplies six guidelines for music education practitioners who are sequencing learning activities…

This forth annual report covers the activities of the Research and Development Center in Educational Stimulation during the 1968-69 fiscal year. To reflect the Center's new programmatic structure, the description of the Center's objectives and activities is organized as follows: (1) Administrative program; (2) substantive programs, including art,…
