This article seeks to provide researchers and practitioners in laboratory education, particularly those involved in the curriculum design and implementation of teaching laboratories at university level, with a conceptual framework and a working model for an integrated assessment of learning domains, by attending to a more holistic approach to…

How people see the world, even how they research it, is influenced by beliefs. Some beliefs are conscious and the result of research, or at least amenable to research. Others are largely invisible. They may feel like "common knowledge" (though myth, not knowledge), unrecognized premises that are part of the surrounding culture. As we…

Two studies examined the acquisition of automatic processing in a total of 22 persons with and 34 persons without mental retardation. An effect of search set size was found for both groups which disappeared with practice. Evidence of automaticity occurred with less practice for subjects without mental retardation. (Author/DB)

The science learning cycle developed by Robert Karplus and others in the 1960's has been a useful model for many science teachers and researchers. This model stresses the use of structured inquiry to organize knowledge acquisition and problem solving. Recent research in the cognitive science tradition, however, has shown that learning and problem…

Linguistic imitation by 48 children with Down's syndrome was compared to that of 57 children without mental retardation. The children with Down's syndrome imitated slightly less. This difference was related to language level and the source of the imitation, suggesting that children with Down's syndrome develop differently with respect to…

This article uses a case study of a deaf-blind infant to examine issues in the early cognitive development of such infants. The study used an ecological approach involving naturalistic observation, videotaping, anecdotal accounts, and the use of four global developmental scales. (DB)

Reasoning and logical thinking can be defined and explained from different perspectives. Three approaches are reviewed in this report; they are: (1) the logical structure approach; (2) the Piagetian approach of developmental stages; and (3) the information processing or memory approach. Four hypotheses related to these approaches were investigated…

This paper describes the mental model children have of their own learning, derived from their behaviors when learning a song. The basic assumption of the study is that behavior is an outward expression of a psychological entity. The song chosen for the study was a complex, unfamiliar Zulu song. Thirty-six children in three age groups participated…

This paper demonstrates a method for constructing long variables using items that elicit partically correct responses across ages. Long variables may be defined by students at different ages (year levels) attempting common items within a test containing other items considered to be appropriate for each age or year level. A developmental model of…

One approach to the study of cognitive processes highlights the distinctions between expert and novice problem solvers. This approach attempts to discover how experts and novices differ in the way they organize, retain and use domain related knowledge. It appears to some that what is learned from expert-novice research can help teachers to teach…

This investigation examined the relationship between problem solving ability and the criteria used to decide whether two classical mechanics problems could be solved similarly. The investigators began by comparing experts and novices on a similarity judgment task and found that experts predominantly relied on the problems' deep structure in…

Responding to recent advances in developmental and cognitive science research on knowledge acquisition, this report presents a theoretical framework for analyzing cognitive development as a process of learning. The first section summarizes three developmental characteristics recognized in both the Piagetian and the quantita experimental tradition:…

Examines the development of intuitive theories of motion among college students and children between the ages of 4 and 12. School-aged children made more erroneous predictions on the path a ball takes upon exiting a curved tube than preschoolers, kindergarteners, and college students. Results related to the "growth error." (Author/BB)

Describes two experiments that examined the effects of quantity and depth of processing on elementary school children's time perception. (HOD)

Presented is a criticism of Lawson's (1988) article on the development of misconceptions of biological concepts. Lawson's response to this criticism follows. (CW)
