Argues that the traditional chemistry laboratory manual is not inherently a cookbook and the modern course manual does not automatically eliminate the cookbook approach. Suggests that it is the nature of the teacher guidance that students receive before, after, and during the laboratory work that makes a chemistry program meaningful and effective.…

Presents a question designed to launch a discovery journey through conjecture, research, serendipitous encounters, proof, answers, and new questions. Reports some discoveries and suggests ways in which to incorporate this strategy into classrooms. Presents a geometry project that incorporates this problem-solving approach to mathematics. (JRH)

Describes a study that examined fifth-grade Finnish pupils' problem-solving processes in a LEGO/Logo technology-based learning environment. Results indicate that learning model and gender account for group differences in problem solving processes, and are interpreted as supporting the validity of discovery learning. (Author/LRW)

Advocates using an end-user approach to microcomputers in production/operations management. This approach requires the student to design and create spreadsheet models to solve problems, enhancing subject area knowledge, creativity, and problem-solving and computer skills. (SK)

This study is one of several conducted by the authors in their investigation of the use of "higher order rules" in the solution of problems. The focus of the current experiment was determination of the compatibility of identified rules with the knowledge of average teenagers, and of the extent to which instruction in higher order rules…

Robert M. Gagne, Ralph W. Tyler, and Wilbert J. McKeachie, in independently prepared statements made before a summer institute on effective teaching, emphasized that good learning is active rather than passive; stresses the learning of principles; exploits the advantages in newness: exploration of something new, a new practice, a principle learned…

Six different methods were used by students to solve the problem of finding the area of a given trapezoid. A seventh method used by textbooks is also discussed. (MP)

A special topics elective course is described. The rationale and organization are discussed and examples of course content and student achievement are presented. (MP)

The objective were to explore some of the ways in which the calculator can be used and to determine the effects. Areas covered are: computation, mathematics readiness, problem solving, and discovery learning. (MP)

The idea of "complete permutations" of n distinct objects is explored in order to investigate an application of the concept that arises in Rex Stout's mystery novel, Too Many Cooks. (MN)

An exploratory problem is presented which involves the identification of all the ways a unit fraction with prime denominator can be written as a sum of two unit fractions. (MN)

A problem concerning the generation of an array of numbers is posed. The author examines the use of this problem in several secondary-school and college classes. (SD)

Briefly discusses several frequently encountered barriers to learning--negative impact on inner self, threatening situations, rewards, and blockage of spontaneous exploration--from both theoretical and practical perspectives. Ways in which Logo is useful in removing these barriers are noted. (MBR)

Reviews Logo programming language's developmental history, including Papert's vision, creation of LISP, and evolution of Logo from LISP; discusses reasons for Logo not becoming a commonplace programming language; describes Logo program design and its utility for serious programmers; and lists sources of further information on Logo.
