Presents an activity that simulates involvement in a paleontology dig in which students in teams unearth a skeleton and follow field procedures for documenting the dig and handling specimens. Provides details of each stage of the project. (DDR)

Describes an investigation that explores students' understanding of the translation, rotation, and deformation of an object. Findings illustrate that students have difficulty appreciating that these different phenomena can occur simultaneously. Discusses some implications for teaching. (DDR)

Three preschoolers performed four sorts with stimulus cards--an untaught target sort and three directly taught alternating sorts considered to self-instruct the target performance. Accuracy increased first in the skill sorts and then in the untaught target sorts. All subjects generalized to new target sorts. Correct spontaneous self-instructions…

This study of 60 Swedish university students examined whether or not acute alcohol intoxication inhibits or facilitates the incubation phase of the creative process. Results found that the participants in the alcohol group produced significantly more incubations in their diaries and significantly higher levels of originality. (Author/CR)

Compares a soft system model of teaching with a hard systems model for learning, essential components of which are perception, memory, and concept formation. Proposes a combination of soft systems thinking and hard systems instruction as a scientific basis for the craft of teaching. (SK)

Presents two examples of using the limitations of calculators to help students understand important mathematical ideas. The first example shows how a simple algebraic calculation can make a recursive model work long enough to perform the job at hand while the second shows how the limitations of a calculator can be used to introduce the need for…

Describes experience using a new approach to teaching induction that was developed by the Mathematical Methods in High School Project. The basic idea behind the new approach is to use induction to prove that two formulas, one in recursive form and the other in a closed or explicit form, will always agree for whole numbers. (KHR)

Recommends the use of concept mapping in science teaching and proposes that it be presented as a creative activity. Includes a sample lesson plan of a potato stamp concept mapping activity for astronomy. (DDR)

Presents the conceptual, philosophical, and methodological basis for the "Procedural and Coding Manual for Review of Evidence-Based Interventions." Discusses key conceptual issues and areas of potential controversy surrounding the manual and the research framework for coding evidence-based interventions (EBIs). Presents methodological…

Presents results of preliminary trials that suggest that the program devised helped UK Year 12 (A-level) learners develop useful concepts of current and voltage, acquire a more integrated understanding of circuit behavior, and overcome their tendencies towards localized and sequential reasoning. Provides learners with a valuable aid for problem…

Explores the effects of students' inquiry during a technology-supported unit of evolution and natural selection on their beliefs about the nature of science. Shows that the inconsistency of individual responses undermines the assumption that students have stable, coherent epistemological frameworks. Indicates differences between student talk…

Investigates the effects of instructional environment on students' conceptual understanding and procedural knowledge of calculus. Uses multiple achievement measures to determine the degree to which students from different instructional environments had mastered the concepts and procedures inherent to first semester calculus. Indicates no…

Presents a teaching experience that resulted in students getting to a point of full understanding of the kinesthetic activity and the algebra behind it. Includes a lesson plan for a traffic jam activity. (KHR)

Describes a laboratory-type activity, liquid assets, used to illustrate, develop, or reinforce central concepts in first-year algebra. These include linear function, slope, intercept, and dependent and independent variables. Presents a group activity for collecting data, transition from group to individual activity in plotting data points, and…

Presents an activity that investigates the reflections on a mirror. Focuses on the relationship between a person's height and the mirror's height. (YDS)
