Cryptography is the science that renders data unintelligible to prevent its unauthorized disclosure or modification. Presents an application of matrices used in linear transformations to illustrate a cryptographic system. An example is provided. (17 references) (MDH)

Describes Socratic Dialogue Inducing (SDI) laboratory methods and procedures developed to increase conceptual understanding in introductory physics laboratories. Gives an example of a typical beginning SDI lab manual section and a representative Socratic dialogue. Describes several examples of laboratory experiments developed for the SDI method.…

Presented are simple activities that can be completed by students at home with the help of a parent. Activities include the topics of sorting, patterning, counting and numbers, geometry, adding, subtracting, and measuring. Each activity describes a series of sequenced tasks related to one of the topics. (KR)

Several types of physics activities that use real-world problems to motivate learners, use computers to assist in developing conceptual understandings, connect problem situations to mathematical models, and use the models to analyze other real-world problems are presented. The topics of racing sports, sailing, and damped harmonic oscillations are…

This problem-solving activity book offers tools for attacking problems in the classroom and beyond (a reproducible card set explaining problem-solving skills, a math problem-solving grid, problem-solving lessons in science, language arts, and social studies, and a poster following scientists as they fight to reclaim an endangered species). (SM)

As in undergraduate education, the knowledge explosion and curriculum crowding in dentistry force greater emphasis on problem-solving skills and assessment of educational outcomes. Dental schools will be challenged to motivate faculty to perform their dual roles as teachers and researchers effectively, and faculty development centers can play an…

Discussed is a program that awards money to institutions that want to develop teacher training programs with national significance. Information on how the funds can be used and how the funds are distributed is included. (KR)

Traces New Zealand's introduction to school mediation, reviewing underlying goals of nonpunitive dispute resolution in the United States and highlighting significant initiatives. The establishment of the Hagley School Mediation Service is described and compared with Hawaii's Dispute Management in the Schools Project. Recommendations for school…

This chapter discusses the origins of the case method, looks at the question of what is a case, gives ideas about learning in case teaching, the purposes it can serve in the classroom, the ground rules for case discussion, including the role of questions, and new directions for case teaching. (MLW)

Described is a theorem which is generally not present in most high school geometry textbooks. Presented are two proofs and two cases which illustrate the use of the SSA theorem. (CW)

Problem-solving strategies which use reflective thinking and inference in mathematics are discussed. Examples are provided with discussions of the learning process. The advantages of this approach are stressed. (CW)

Presented are 27 science activities for secondary school science instruction. Topic areas include microbiology, botany, biochemistry, genetics, safety, earthquakes, problem solving, electricity, heat, solutions, mechanics, quantum mechanics, flame tests, and molecular structure. (CW)

Four naturalistic methods for assessing college student learning styles are discussed: direct observation of student behavior, in-depth interviews with students, analysis of self-directed learning projects, and analysis of the guiding metaphors used by students in describing the teaching-learning process. Each suggests ways teachers can adapt to…

Describes decision-aiding software, Policy/Goal Percentaging (P/G%), that can process a set of controversial alternatives when used with microcomputer-aided instruction. The benefits and objectives of microcomputer use are discussed, and applications of the software to problems in the fields of natural sciences, social sciences, and the humanities…

The last decade has shown a steady increase in the introduction of problem-based learning (PBL) in the education of health professionals. A variety of medical and dental schools have implemented PBL using different formats incorporating self-directed and small-group learning, illustrating the many options this combination of techniques offers.…
