Describes an educational game in which students get the opportunity to review Lewis structures and molecular geometries through problem solving activities as a team. (YDS)

Discusses five strategies to use in creating an environment that will foster the development of critical thinking. To make thinking the subject of instruction; focusing on the key aspects of higher-order thinking; providing opportunities for continual, explicit practice; questioning and developing an investigative nature; and reinforcing the…

Discusses student difficulties in problem solving. Presents a structured approach to one-dimensional constant acceleration problems. Provides researcher's experience including an example problem, advantages of the approach, and student responses with two illustrations of problem solving. (YP)

Presents a procedure that students can use to determine the center of mass of a thin (two-dimensional), homogenous object experimentally, analytically, and numerically. Requires students to use three distinctly different approaches to a single problem and necessitates a combination of laboratory skills, a knowledge of fundamental calculus, and…

Describes problems that are presented in the form of experiments. The philosophy, method of solution, and several examples of mechanics experiment problems are described. (LZ)

Presents correct solutions to an osmosis problem of two high school science students who relied on inaccurate and inappropriate conceptual knowledge. Identifies characteristics of the problem solvers, salient properties of the problem that could contribute to the problem misrepresentation, and spurious correct answers. (27 references) (Author/MKR)

Examines how problem solving in the domain of Mendelian genetics proceeds in situations where solvers' mental models are insufficient to solve problems at hand (model-revising problem solving). The study addressed the heuristics characteristic of successful model-revising problem solving and other aspects of student model use. (LZ)

Provides six problems to help students understand new concepts of force using situations they already understand concerning velocity, acceleration, and momentum. (MVL)

Provides a method of solving vector and force problems that is less complicated for the learner. Gives several examples concerning projectiles and inclined planes. (MVL)

Describes the graphing calculator as a new graphical approach to standard physics problems. Presents a collision problem to illustrate its use. (JRH)

Presents concept mapping as an effective tool for developing an integrated curriculum. Includes examples of concept maps that represent an entire veterinary curriculum, specific courses, and case-based exercises. (21 references) (Author/JRH)

Applies a theory of analogical thinking as satisfaction of multiple constraints to the use of analogies in instruction. It shows how the strengths of particularly good analogies and the weaknesses of particularly bad ones can be understood in terms of pragmatic, semantic, and structural constraints. The constraints suggest lessons for how…

Suggests that teachers should consider which questions to ask as a part of instructional preparation. To ensure that diversity and critical thinking are involved, a teacher should use a taxonomy for a template when writing questions. Presents and discusses Bloom's taxonomy, Gagne's levels of learning, and a taxonomy for general science process…

Teachers are being asked to provide students with activities that are relevant, interrelated, and challenging. This article describes an activity, Zoo Investigation Cards, that place students in an investigative problem-solving situation and allows them to observe living organisms in the complex system of their natural habitat.
