Piaget's formal operational stage is related to the teaching of science by focusing on the development of paper and pencil tests for determining students' cognitive level of development and on procedures for helping concrete operational students improve achievement and become more formal in their thinking. (JMF)

Studied high school and university students' use of mental representations in reasoning, and the developmental progression of their reasoning with concrete and abstract content. Reasoning was more difficult with abstract content. Abstract problems followed by concrete ones led to reduced concrete problem performance for high schoolers but not for…

Investigates whether the formal schemata and propositional logic are acquired gradually across age during adolescence, in agreement with Piaget's logical analysis of the structure of formal thought, or acquired in wholesale spurts, thus disagreeing with Piaget's theory. (GA)

Examines why analytical thinking should be a major focus of teaching in the reading and writing classroom. (HOD)

Briefly reviews psycholinguistic research, describes six categories of utterance, and reports on research into the relationship between level of thought and length of speech. Results indicate that both teachers and students take successively longer to express higher-cognitive types of utterances. (EAO)

Assesses the ability of tenth grade students (n=364) to acquire meanings of graphs that are frequently used in their biology textbooks. Indicates that the main source of failure to process information equally well from tables and graphs was not a lack of basic analytical skills but rather a lack of understanding of the relationship between…

Toward the improvement of teaching history and to provide student insights into the study of history, a course involving structure, relevancy, an interdisciplinary approach, and innovation is suggested which advocates analyzing what has happened in the past as a whole, as revealed by the various sciences of archaeology, anthropology, paleontology,…

Investigates the attainment of abstract and concrete concepts and the use of pseudoexamples to move concrete thinkers to abstract levels in secondary school chemistry classes. Findings reveal abstract students achieve significantly higher means on both concrete and abstract concept attainment and that pseudo examples have no effect on the ability…

The ReQuest procedure, designed to teach students to raise questions independently, has many components that lend themselves to solving some of the problems faced by the teacher of juvenile delinquents. (HOD)

Compared laboratory and naturalistic content influences on formal reasoning tasks of 90 13-, 15-, and 17-year-olds, focusing on tasks requiring ability to control variables. Results indicate that 8 to 20 percent of performance variance was associated with task content. Content effects were also shown to reflect expectations about task variables.…

Two years after the end of a two-year intervention program set within the context of science learning intended to promote formal operational thinking, achievement of students (n=234) was tested by their results on British National examinations taken at age 16. Male experimental subjects achieved an average of 40 percent more grades of C or above…

Twenty-two secondary students with learning disabilities were successfully taught the principles of scientific reasoning. Using student-teacher dialogs, students analyzed information presented in magazine articles and advertisements. Students improved their ability to identify the principal claim made in an article or advertisement, graph the…

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…

This article presents specific instructional approaches and examples to develop the algebraic reasoning skills of middle and secondary students with mild disabilities. Discussion of the National Council of Teachers of Mathematics standards identifies general principles, content standards, and process standards. Discussion of effective instruction…

The Inductive Reasoning and Analytical Reasoning tests of the Johnson O'Connor Research Foundation have been analyzed in a factorial study including marker tests for two commonly recognized reasoning factors, induction (three tests) and logical reasoning (two tests). The primary purpose of the study was to determine the extent to which the Johnson…
