Goals and objectives of many state and local environmental education programs have included developing students with knowledge, skills, positive attitudes and motivation to take action, to prevent and to resolve environmental problems. This digest describes variables involved in developing responsible environmental behavior and some teaching…

This paper takes the position that logical knowledge is distinct from conceptual and procedural knowledge and can make a unique contribution to the understanding of knowledge acquisition. This view of logical knowledge departs from the traditional Piagetian view of stages and the overriding view of logic as the sole means of constructing new…

Two experiments examining adults' use of dimensional adjectives focused specifically on the distinction made between height and overall size as determiners of "bigness." The subjects in both experiments were college students. In the first, the hypothesis that the meaning of "big" shifts as a function of the object being…

The middle school grades are a period of transition: a time in the formal educational process when immature children develop into young adolescents who are better prepared for the rigors of higher education and life itself. In order to help children master the sophisticated social studies concepts and skills necessary for higher secondary…

Aware that children conceive of different types of trust, a study examined 60 children's conception of trust. The subjects comprised three age groups: 6-7 years old, 8-9 years old, and 10-11 years old. Each subject was interviewed on the basis of three stories. The stories depicted a hypothesized violation of trust in a moral context (lying),…

Researchers in medicine, education, and related fields continue to make new discoveries about how the brain functions or malfunctions. The implications of studies of how young children learn compare favorably with those of educators such as Maria Montessori, Jerome Bruner, and Jean Piaget. These researchers saw growth and development as a series…

This paper presents an examination of the construction of logic in multidigit subtraction. Interviews were conducted with 90 grade 2 and grade 3 students to determine whether they understood the logic of borrowing and whether the construction of the logic was related to procedural expertise or corresponding conceptual knowledge. Of 34 students…

To discover whether increased exposure to and understanding of figurative uses of language would result in improved performance on a metaphorical language comprehension test, gains were measured on a figurative language test that was administered twice, approximately four months apart, to a total of 319 elementary school children in Harlem, New…

This case study presents a descriptive portrait of how one general mathematics teacher transformed her classes from a computational to a conceptual orientation. The outcomes of the transformation for student learning and instruction are discussed. The findings suggest student gains in computational competence, mathematical effort, and attitude via…

A research study designed to measure understanding of economic terms among 13- and 14-year olds is summarized. For purposes of the study, two tests were constructed: a 10-item questionnaire focusing on definitions of words such as banking, production, costs, money, and wealth, and a compilation of drawings and photographs developed to reflect…

Recent research in cognitive science and science education suggests that science-naive individuals have an understanding of the natural world based on their interpretation of everyday experience. This can make the process of conceptual change difficult. This paper presents ideas related to the acquisition of knowledge in astronomy. A theoretical…

The Educational Technology Center has attempted to develop a series of computer based learning environments to support the learning and application of multiplicative reasoning. The work and software described in this paper, including the teaching experiment that generated the error phenomena examined, is part of a larger ongoing research project.…

One approach to the study of problem solving is to observe how people with different skills (novices and experts) solve problems by collecting and analyzing protocols and formulating models to obtain solution processes. Individual differences are subsequently explained by the differences in the knowledge possessed, as embodied by the sets of…

The study examined the effectiveness of a program to improve the cognitive skills of 91 hearing impaired college students. Experimental students received systematic cognitive instruction focusing on specific generalizable skills during the experimental period, several times per week, in the contexts of their regular college classes. Instructors of…

This digest suggests that research findings can provide teachers with verification and clarification of how children learn mathematics, and thus how to teach mathematics more effectively. Three topics are discussed: (1) number concepts; (2) problem solving; and (3) manipulative materials. (PK)
