Reports a study that examined the effects of conceptual orienting questions and differences in prior knowledge on factual learning and problem solving in biology. Tenth graders who participated in control or orienting questions groups completed posttests. Results indicated that question groups outscored the control group. (SM)

Using an integrated curriculum anchored in science and multimedia technology, Project LINCOL'N (Living in the New Computer Oriented Learning 'Nvironment) facilitates active learning for all students. The project's vision is to enable all students, including those with disabilities, to engage in authentic learning in a problem-solving environment.…

Presents an introductory activity in statistics in which a mathematics class is divided into groups to "draft" teams of major league baseball players. Describes the drafting procedure, charting the team, scoring, roster changes, and gathering and evaluating data. Includes draft list, daily box scores, and cumulative box scores. (MKR)

Compares seven positions on media influences on learning that were presented in a previous journal issue; discusses the conflict between advocates of a given approach versus integrated approaches to the solving of complex problems; and presents a model that links cognitive processes to computer-based prescriptions for improvements in learning. (35…

Surveyed 53 Greek elementary school teachers and 55 teacher trainees regarding school psychologists. Subjects rated usefulness of school psychologist in solving learning, conduct, and attention problems of students. Findings suggest that teachers and trainees held positive perceptions about school psychologists. Willingness to follow through with…

The most time consuming and expensive step in developing expert systems is knowledge acquisition (KA), and it is important to determine how the limited resources for acquiring knowledge should be allocated across different sources. This paper develops a model that determines how KA resources should be spent and how such a model may be used. (23…

The errors and strategies made by students who consistently use the incorrect-addition strategy on "hard" ratio tasks were investigated. The characteristics of these "adders," such as awareness of noninteger multiples, the use of fractions and decimals, awareness of both within and between ratios, and distinguishing nonratio…

Results of a systematic investigation into university students' (n=236) misunderstandings of d.c. simple circuit operations are reported. These results provide evidence of various misconceptions present before and after teaching the following topics: a battery as a source of constant current; the functional relation expressed by Ohm's law; power…

Presented is a proof where special attention is accorded to rigor and detail in proving the lemma that relates ruler-and-compass constructions to arithmetical operations. The idea that some angles cannot be trisected by a ruler and compass is proved using three different cases. (KR)

Presented is the theorem proposed by Volterra based on the idea that there is no function continuous at each rational point and discontinuous at each irrational point. Discussed are the two conclusions that were drawn by Volterra based on his solution to this problem. (KR)

Describes the design and implementation of a major collaborative assignment in which students investigate and produce written and oral solutions to a problem with a national perspective experienced by a community corporation, business, governmental, or not-for-profit organization. (KEH)

The effectiveness of specific dimensions of adult mediation on preschoolers' self-regulation of a model consultation strategy was evaluated using microcomputer puzzle tasks. Findings suggest that children's acquisition of the model consultation can improve over a short period of time with culturally mediated instruction. (Author/GLR)

In whole concept mathematics, students actually use math and understand the practicality of what they are studying. This learner-centered approach treats students with respect, uses real-life situations, encompasses a variety of learning styles, and involves cooperative learning techniques. (SK)

It is proposed that algorithms and heuristics are useful in improving professional problem-solving abilities when contextualized within the academic discipline. A basic algorithm applied to problem solving in undergraduate engineering education and a similar algorithm applicable to legal problems are used as examples. Problem complexity and…

Describes current issues and difficulties inherent to the topic of critical thinking in physical education; also presents and discusses a schematic representation of a theoretical critical thinking model for the psychomotor domain (cognitive organizing, cognitive action, cognitive and psychomotor outcomes, and metacognitive monitoring).
