A mapping procedure based on the SOLO Taxonomy developmental model was used to classify the problem-solving strategies of students (n=34) in grades K-2. Only one multiplication problem was used to isolate three components of the problem-solving procedure. (MDH)

Kindergarten (n=30) and grade 1 (n=15) students of contrasting socioeconomic backgrounds were interviewed to assess their knowledge of number word sequences and spatial patterns and their ability to recognize numerals and use counting to establish numerosity of visible and screened collections. Findings indicate greater variation in abilities…

Examined the quality of responses of six classes of grade six students to four questions requiring multiple and generalized solutions posed under varying conditions. Results indicated that this type of question can be useful in classrooms because students can respond at a variety of levels. (13 references) (MDH)

Twenty-four sixth-grade children participated in clinical interviews on ratio and proportion before receiving instruction in the domain. Student thinking was analyzed in terms of mathematical components critical to proportional reasoning. Two components, relative thinking and unitizing, were consistently related to higher levels of sophistication…

Examined the accuracy with which parents judged their children's preferences, and the relationship between parental accuracy and children's cognitive performance. Mothers were more accurate than fathers; parents of fifth graders were more accurate than parents of second graders. The accuracy of parents' predictions was related to children's…

Discusses the influence of culture and family and the importance of self-esteem in the development of competency in young children. Describes the role of the teacher in creating a developmentally appropriate environment that fosters self-initiated learning and a personal locus of control. (SH)

Presents guidelines on ways teachers can create an atmosphere that will encourage young children to use higher level thinking skills in all their classroom activities. Describes five learning experiences that promote such thinking abilities. (BB)

Argues that the dichotomy between domain-specific and general theories of cognitive development addressed in the "Merrill-Palmer Quarterly" special issue is unproductive. Suggests that polarities of generality and specificity exist in creative tension as seen through developmental processes. (Author/BB)

Identified is research related to concept formation; the chronology of identity and equivalence conservations; the relationship of mental age to performance on number concept tasks; perceptual, attentional, linguistic, and social factors; and the potential use of cognitive developmental criteria as measures of ability for both normal and retarded…

Discussed is a constructivist model of science learning and its possible use in the treatment of science misconceptions. Science learning as conceptual and methodological change is described. (KR)

Discussed are expert systems development and teaching, the representation and processing of knowledge, knowledge representation in chemical engineering, and expert systems in chemical engineering. The seven phases of expert system development are illustrated. (CW)

Cognitive, academic, and behavioral characteristics of 42 children with learning disabilities were assessed from identification at age 6-7 to the age of 11.5. At endpoint, resource students showed a drop in verbal intelligence quotient and lower achievement compared to mainstreamed students, though there were no differences at the time of…

Based on the premise that body experiences interfere inconveniently with scientific ideas in mechanics instruction. Suggests that learning processes start with body experiences and, with guidance, transform them into something scientific. Discusses this process for the static and kinetic aspects of force and for measurement. (MDH)

Raises questions regarding what students are perceiving when concrete models are used to represent abstract scientific concepts. Discussion of several exploratory investigations on the role of models in science teaching is presented in three areas: (1) interactions with students; (2) effectiveness of models; and (3) spatial ability and models.…

Differences in component processing skills of students of different ages and developmental changes over 1 year were studied for 96 students in grades 2 through 4 and 59 of them in a follow-up. Results trace the development of component processing skills and suggest a theory of the development of component skills. (SLD)
