When trained on all components, fifth and seventh graders became very competent in dealing…

Five articles explore various theoretical aspects of problems and problem solving skills. Highlights include strategies to learn problem solving skills; knowledge structures; metacognition; behavioral processes and cognitive psychology; erotetic logic; creativity as an aspect of computer problem solving; and programing as a problem-solving…

Discusses the use of Aristolean logic in developing practical reasoning and arguments. Asserts that practical arguments are used to explain why an individual took action based on practical reasoning. Contends that this approach should be used by teachers in applying research findings to instruction and in encouraging students to support their…

Describes the use of practical rationality from the vantage point of a graduate student and an elementary teacher in an urban school. Discusses how using the approach led to revised policies regarding reading strategies and discipline. Contends that practical argument philosophy can be useful in practical classroom applications.
