A general model of conceptual change which is largely derived from current philosophy of science, but which can illuminate learning as well, is described. Some features of this model are illustrated by interviews with students studying special relativity in physics. Finally, some pedagogical implications are presented. (Author/PB)

Discusses the characteristics of a nurturing and of a constraining classroom environment and the effects of each on children's learning to write. (HTH)

Summarizes a study to widen the applicability of Piagetian theory-based conflict methodology from individual situations to entire classes. A Solomon four group design was used to study effects of conflict instruction on students' (N=127) ability to conserve volume of noncompressible matter and to apply that knowledge to gas volume. (Author/JN)

Six studies investigated the use of pictorial material in a group setting to measure the cognitive level of children (age 7 to 11) on eight Piagetian concepts. Children were low to middle socioeconomic status with 60 percent Spanish surnames. Factor analysis and clinical administration supported test validity. (Author/CTM)

Scores on the Home Observation for Measurement of Environment (HOME), designed to reflect parental support of early cognitive and social development, were correlated with elementary school achievement five to nine years later. Results supported the predictive value of the instrument for school achievement among low-income families. (Author/DB)

Studies the scientific curiosity and inquiry of 226 high school students from grades 10 to 12 who were studying the Israeli adaptation of the Biological Science Curriculum Studies (BSCS) program in eleven different schools representing city and Kibbutz Schools in Israel. (HM)

Eleven papers comprise the special issue on learning disabilities and deal with definition, prevalence, promising research strategies, and potentially effective educational treatments oriented toward the processes of thought and the "learning to learn" strategy. (DB)

Investigated the interaction between science teaching strategy (semideductive, structured inductive, hypotheticodeductive) and selected learner characteristics (Piagetian cognitive level and field independence) in terms of student achievement in science. Achievement of undergraduate elementary education majors (N=77) in a general science program…

Studies children's justification of message choices as characteristics of their reasoning processes. Indicates that interpersonal reasoning increases in sophistication and complexity over the age groups studied and that females reason at a higher level than males. Situational influences on level of interpersonal reasoning were also found. (JMF)

Described are ways in which curriculum in science and mathematics may be shaped to the adolescent. Several examples relate to cognitive development, neurological functioning, physical changes, social evolution, and moral growth of the adolescent. (DS)

Described is a three-phase model for teaching problem solving to the middle school student. Phases include cue attendance, thinking aloud, and developing diagrams of steps to solutions. Because middle school students are in a transitional period in their cognitive processes, implementation of problem solving skills seems appropriate. (Author/DS)

This study investigated a way of teaching Israeli student-teachers about the nature of classroom activities in the cognitive domain by training them to observe actual lessons. Observation was limited to the activity of pupils in science classrooms rather than to that of the science teachers. (HM)

Using studies from many countries, the author reviews the advantages and disadvantages of three designs for bilingual instruction: delivery in the second language, initial instruction in the mother tongue, and mixed delivery in both languages. Cognitive development and students' attitudes toward their native language are considered. (SJL)

Two tests of cognitive development, the Cartoon Conservation Scales, Levels I and II, were designed to measure Piagetian stage-related constructs for children of different age groups. The tests were factor analyzed within age levels and were also analyzed using scalogram and tabular methods to test sequential hypotheses. (Author/CTM)
