This study describes the relationship of two cognitive variables, logical thinking and disembedding ability, to learners' abilities to make conceptual shifts from less acceptable to more acceptable conceptual understandings of a physical phenomenon. The difference in the logical thinking and disembedding ability of students who exhibited different…

A major goal of mathematics teaching is the involvement of students in the personal process of discovering mathematical ideas and formulating problems. The process of an inductive leap followed by a deductive argument is used in mathematics courses at Phillips Exeter Academy (New Hampshire). Mathematical problems are presented in which the givens…

Thinking-aloud protocols of human problem solvers working on geometry problems are presented and discussed. Protocols were obtained from six individuals working on nine different problems in which constructions were used. Nineteen protocols are presented with annotation and discussion, and other protocols are summarized. The primary purpose of the…

Despite the endorsement of problem solving by social studies educators as an important process for students to learn, research shows that most social studies teachers do not include such higher level intellectual processes in their teaching. This paper specifically deplores the lack of attention to inquiry problems. The authors suggest that social…

This document discusses the relation between adolescents' expertise (their informational background, which can be accurate or inaccurate, about a particular task or subject) and their formal operational reasoning, and reports the results of three studies of the effects of children's expertise on reasoning. In Study I, adolescents from a rural…

The National Instititute of Education sponsored a conference on the future of research in adolescent reasoning. This report reflects this conference discussion, which focused on: (1) the theoretical basis for research programs in the area of adolescent reasoning; (2) research programs likely to be effective in gathering information relevant to…

Reports a study which examined objective ratings of the moral issues expressed in the Defining Issues Test (DIT) items in relation to verbal reports of the reasoning with which those ratings were generated. Finds that differences in the educational level of the subjects were significant. A case is made for verbal assessment of information on…

Investigated the development of formal reasoning among students (ages 10-18 years) from predominately White, middle-class communities located in rural, suburban homogeneous, and suburban heterogeneous areas. Results indicate clear differences among communities in formal reasoning ability. Implications for using science instruction to promote…

Describes a schema-theoretic view of how analogies enhance students' prior knowledge; reviews some of the recent studies using analogies to assist students' comprehension of science text; and illustrates the use of an analogical study guide in biology. (HOD)

A study of 191 juniors and seniors from 6 Oahu high schools tested their ability to interpret and construct search statements after reading brief instructions on concept analysis, Boolean operators, and search statement format. On average, students made two errors per statement; scores and types of errors are examined for influences of gender and…

This booklet is part of the "Getting to Grips with..." series, which is intended for the general reader who wants to understand important trends in vocational education and training. It is designed to provide the reader with an understanding of the concept of key technologies, to describe the potential importance that this way of…

A sample of 217 students (from grades 4 to 8) who were enrolled in an elementary school science-oriented gifted and talented program were compared to 91 mainstreamed subjects in grades 7 through 10. Assessement instruments included: a battery of Piagetian measures designed to assess combinatorial reasoning, probabilistic reasoning, and the ability…

On the basis of studies reported elsewhere (SE 019 717 and 719) the author discusses the implications of research on cognitive development for teachers whose subjects involve an understanding of proportionality. Several common methods of teaching chemistry students to use proportionality in chemical problems are described. Research on the…

Attempts to show that not only can density be taught to lower ability pupils but that by doing so, there is the possibility of assisting pupils to develop their reasoning powers. Lists teaching activities that help in this process. (CW)

If British Columbia education policy wanted to promote growth in numeracy and mathematics, the curriculum would provide opportunities to use mathematical concepts in social situations and give students time to move from concrete to abstract thought. Instead, the curriculum emphasizes extensive mechanical understanding and algorithmic manipulation…
