Examines how problem solving in the domain of Mendelian genetics proceeds in situations where solvers' mental models are insufficient to solve problems at hand (model-revising problem solving). The study addressed the heuristics characteristic of successful model-revising problem solving and other aspects of student model use. (LZ)

Describes an artificially intelligent multimedia computerized instruction system capable of developing a conceptual image of what a student is learning while the student is learning it. It focuses on principles of learning and adaptive behavioral control systems theory upon which the system is designed and demonstrates multiple user modes.…

Reviews the literature on the relation between early memory development and corresponding changes in brain development of infants. Finds that an adult-like form of explicit memory emerges between 8 and 12 months of age, drawing heavily on limbic and cortical structures. Offers theoretical perspectives for studying the ontogeny of memory. (JW)

Two experiments examined whether 40 infants would reenact what an adult did or intended to do: (1) infants observed an adult unsuccessfully attempt to complete 4 target acts; and (2) children observed a mechanical device tracing the adults' actions. Infants could infer adults' intentions and imitate target acts, suggesting that children can…

Examines three ways that constructivism is aligned with multicultural education in formal educational environments: (1) learners organize ideas in unique ways; (2) learners' self-awareness and self-concept influence learning; and (3) a learner's personal history filters new information. (GR)

In an authentic learning setting, technology has the power to support students and teachers in obtaining, organizing, manipulating, and displaying information. According to an Office of Educational Research and Improvement case study, reformed classrooms begin with an authentic, challenging task; have all students practice advanced skills; and…

The performance of a 3-year-old with Rett Syndrome in a Contingency Intervention Program using head and hand switches and adapted toys was assessed over 18 months. Learning contingent control of the stimuli positively motivated the child, promoted attention to toys and objects, and generalized to the classroom. (SW)

Notes that musical aptitude is not developed or nurtured through mere "exposure" to music but through active participation in singing and moving to music. Provides a rationale and suggestions for teaching singing in early childhood classrooms. (HTH)

Notes the importance of outdoor play to the early childhood curriculum. Explores the purpose and nature of playgrounds, and presents a staff development model based on playground contents, safety, and functions. Also notes some playground problems teachers can avoid with close observation. (HTH)

Presents an exploratory experience that allows students an opportunity to practice science process skills and use all of their senses. Describes a fruit study activity, appropriate for grades three through six, that incorporates the learning cycle (exploration, concept development, and concept application) and cooperative learning strategies.…

Discussion of hypertext and its uses in the learning process focuses on an experiment in which undergraduate students used hypertext for computer-based learning about databases. Results of a survey of students which explored when and how they used the hypertext, for what purpose, and the types of searching they preferred are reported. (12…

Describes the three phases of the learning cycle (exploration, conceptual invention, and expansion) and explains how they can be used in educational assessment. The use of semantic mapping, concept mapping, and mental modeling in the evaluation of student learning is described. (PR)

Individual differences in industriousness are discussed. It is proposed that reinforcement for increased physical or cognitive performance, or the tolerance of aversive stimulation, gives a reward value to the sensation of high effort and reduces effort's aversiveness. Applications for self-control, moral development, and education are described.…

This case study of a 30-year-old woman with a developmental learning disability (including anomia, auditory processing problems, difficulty in learning reading and spelling skills, and a poor sense of number) suggests that all these impairments may be explained in terms of a sequential processing deficit. (Author/DB)

Robert J. Sternberg's research on cognitive style and model of "mental self-government" at all educational levels have led to a pilot elementary/secondary curriculum to help students develop common sense and practical judgment as well as intellect. The interinstitutional effort between Yale and Harvard universities includes Howard…
