This paper reviews an approach for finding optimal solutions to the traveling salesman problem, a well-known problem in combinational optimization, and describes implementing the approach using the MAPLE computer algebra system. The method employed in this approach to the problem is similar to the way ant colonies manage to establish shortest…

The University of South Carolina at Hilton Head offers a major in Hotel, Restaurant, and Tourism Administration (HRTA). Many students in the HRTA major take both the HRTA Tourism course and a business calculus course. An interdisciplinary research project was designed in an effort to interest these students in the power of calculus as a…

This study assessed the impact that reflective journals used in an introductory college science course had on preservice teachers' science literacy. Fourteen preservice teachers enrolled in an introductory physical science course taught using a variety of constructivist instructional methods (hands-on activities, cooperative group work,…

Instructional resources that employ multiple representations have become commonplace in mathematics classrooms. This study will present computer software, LaborScale which was designed to improve seventh grade students' word problem-solving skills through computer-based multiple representations including graphic, symbolic, and audio…

This section concerns pattern recognition activities related to the properties of cubes and is suitable for reproduction in worksheet and transparency form for classroom use. (JP)

Describes planning and implementation of innovative community college course utilizing office machines to develop problem solving skills in business mathematics. (AG)

Outstanding teachers Meet and discuss instructional problems excluding other teaching matters. Article presents teacher opinions of their progress as well as seminar goals. (RK)

Discusses some central ideas emerging from a systematic approach to teaching scientific problem-solving skills. Areas considered include: insights derived from naturalistic studies; effective problem-solving methods; problem-solving procedures; characteristics of the knowledge base (focusing on functional conceptual building blocks, knowledge…

Teachers should consider using strategy games to introduce students to problem solving in an enjoyable way. Advantages of games, criteria, games and variations to use, and classroom organization are each discussed. (MNS)

Visualization is an effective technique for determining exactly what students must do to solve a mathematics problem. Pictures and charts can be used to help children understand which mathematics facts are present and which are missing--an important step toward problem solving. (PP)

Discusses areas related to teaching science-related, value-laden, real-world problems. These include potential/limitations of science and scientific method, how science-based information fits in with other kinds of information, how preconceptions about problems/issues affect scientific problem solving, and utilization of different educational…

The easy availability and popularity of newspapers enhance their use in the classroom. The material presented is grouped under: (1) "Comparative Shopping and Estimation Activities"; (2) "Buying and Furnishing Houses"; and (3) "Graphing, Probability, and Statistics." Teachers are encouraged to consider such applications in involving pupils in…

The pendulum and balance beam were studied. The principal question addressed was whether students could substantially and quickly benefit from a teaching strategy explicitly designed to promote transfer. About half the subjects could acquire in brief time a procedure for transferring knowledge to novel tasks. (MP)
