Investigated is the extent to which students' nonscientific beliefs change by comparing before and after instruction as a function of students' reasoning skill. Nonscientific beliefs discussed include special creation, orthogenesis, the soul, nonreductionism, vitalism, teleology, and nonemergentism. (KR)

Examined and compared the logical thinking skills and science process skills of junior high school students in North Carolina (n=3,291) and Japan (n=4,397) by grade and by gender. Results indicated that Japanese students in grades seven, eight, and nine performed significantly better than North Carolina students in both areas. (MDH)

Classroom teachers frequently use various programs, strategies, and techniques to enhance student thinking, including questioning, writing, and general information processing (meaning construction, encoding, matching, analyzing, representing, and abstracting). The paper notes other strategies not used or underutilized by teachers. (SM)

Two studies examined abstract conditional reasoning. Findings indicated an increase in use of formal justifications with grade, and that abstract reasoning was facilitated by realistic context. Findings supported the idea that such reasoning may represent a qualitative change in reasoning abilities and that its development relies on appropriate…

Examinees can correctly answer many Scholastic Assessment Test (SAT) reading items when the passages accompanying the items are missing. According to one hypothesis, examinees use information from other reading items (cognates) belonging to the same passage. The purpose of this study was to test that hypothesis for the revised SAT (SAT-I) reading…

A cognitive or internal representation refers to an organized system of information which reflects certain, but not all, of the information about reality being represented. This paper considers various opinions, controversies, and debates about what representation is, how it comes about, and what forms of representation can be distinguished. The…

Investigates factors affecting students' ability to consistently apply the concept of adaptations. Individual interviews were conducted with 74 Year 10 students in Australia, of whom only 47% showed an understanding of the concept. It was found that the students were more likely to apply the concept to vertebrates. (AIM)

Argues that the syntactic and mental model accounts of the suppression effect in deductive reasoning are inadequate. Proposes a relative salience model. Describes a test of predictions from this model in a suppression model, which obtained evidence of convergent validity for the salience construct. Results could not be reconciled with either the…

Three experiments with 276 college, secondary, and middle-school students extend the research of G. T. Fong and others in teaching students abstract rules. Results support a revival of formalist views of transfer: that teaching formal rules about inference making can improve reasoning and support transfer. (SLD)

Longitudinal data on conversations recorded from 1 child between 18 and 27 months of age and 3 children between 27 and 62 months were analyzed to chart acquisition of the word "if" and of conditional inference. Within six months of speaking their first "if," children produced "ifs" at the same rate and forms as…

Effects of undergraduate training on inductive reasoning and logic were examined. Social science training produced significant effects on statistical and methodological reasoning. Natural science and humanities training produced significant effects on conditional logic reasoning. Results indicate that reasoning is taught and generalizable. (BC)

A study with 57 second graders identified some logically irrelevant transformations that children considered relevant in relation to the weight of an object. Two logically relevant transformations, movement upward and movement downward, were irrelevant to the subjects, whether texture, continuity, temperature, and darkness were generally…

Twenty-eight sign language interpreters participated in a battery of tests to determine if a profile of cognitive, motor, attention, and personality attributes might distinguish them as a group and at different credential levels. Eight interpreters held Level II and nine held Level III Virginia Quality Assurance Screenings (VQAS); the other 11…

This paper contains a consideration of the nature and role of warrants for research conclusions in educational research. The paper argues the need for an explicit warrant in the form of a logical and persuasive link between the evidence produced and the conclusions drawn (with appropriate qualifications and caveats). It describes social scientific…

A study investigated whether expressive writing facilitated abstraction in language use, thereby improving reading comprehension. Ninety students enrolled in four required basic skills reading courses at a suburban community college in New Jersey were divided into a control and an experimental group. Students in the experimental group wrote…
