Presents a model of instructional design which links cognitive learning theory and instructional prescriptions. Topics discussed include knowledge types and knowledge acquisition; memory system components; learning time; learning objectives, including skills, cognitive strategies, and creative processes; instructional methods that relate to…

Investigates how Brazilian child candy sellers form and use mathematical understandings. Finds that sellers use knowledge acquired through business activity to work school problems, while only a limited part of school learning is applied to the out-of-school situations. (FMW)

Peer helping provides critical opportunities for practice and reflection as a means of supporting psychosocial development. School counselor skill and knowledge play an important role in the process of peer program development and success. Provides steps for developing a successful program and a sample developmental training model. (JBJ)

Reports on a study of Russian parental attitudes regarding appropriate age of initial school attendance and decisions regarding secondary education. Finds that 80% of parents of young children support kindergarten education. Includes 14 tables of data from the study. (CFR)

Compares case studies of early childhood education in schools in Germany and Ireland. Both schools emphasize the importance of children's emotional-spiritual development, but while Irish children are already in formal education, German schooling defers beginning of formal learning. Concludes that more teacher interaction with children in German…

Examined the role of biological factors, such as perinatal complications, and psychological factors, such as maternal attitudes, in predicting developmental outcomes in preterm children. Findings support the main effects model of biological and environmental factors in explaining developmental psychopathology, but also the interactional model, as…

Discusses collaborative writing with hypermedia and multimedia tools as well as the requisite hardware and software support that foster cognitive and social skills. Proposes research on the impact on and possibilities for students and teachers using collaborative writing in hypermedia environments. (102 references) (JKP)

Reports on an exploratory study of a metacognitive approach to teaching low achieving secondary students. Asserts that the research team hoped to examine a process whereby a dialog about learning processes would develop. Finds that all students indicated that they were able to focus on learning as a topic of conversation. (CFR)

Compared the use of conditional logic in adult-adult and adult-child conversation. Results indicated that conversation patterns and inferences were similar except that children made fewer independent inferences and shifts in taxonomic level and responded more frequently to socially controlling statements than did adults. (AA)

Fourth grade children (n=20) were matched on a pretest and randomly assigned to either a wooden base-10 block or computerized microworld group. Instruction was designed to establish relationships between notation and meaning, extending whole number numeration to decimal numeration. Neither group changed whole-number notational methods nor had…

Reports a study to examine secondary school students' (n=200) responses to two figurally and spatially similar problems from mathematics and science that require different responses before and after instruction. Results indicated that most students gave the same response to both questions. Reasons for this pattern are discussed. (MDH)

Measured physical and cognitive development of 7- to 10-year-old Brazilian children in 3 social groups. Domestic servants' children were taller and heavier than children in slums, and shorter than middle-class children. Domestic servants' sons scored similar to slum-dwelling boys on cognitive measures. (BC)

Presents the reactions of a mathematics educator and a mathematician to a seven-year-old student's response for finding square numbers. Reflects on the mathematician's focus on the mathematics of the problem and the mathematics educator's focus on the student's systematic way of working, and discusses the common focus of student creativity. (MDH)

Discusses concerns for mathematics education research on algebra and requestions methods that focus on the Piagetian concept of cognitive obstacles. Suggests the use of computer-based environments to develop the concept of variable and offers research findings indicating that experiences working with variables in LOGO influences student…
