A 19-step general evaluation model is described through its four stages: identifying problems, prescribing program solutions, evaluating the operation of the program, and evaluating the effectiveness of the model. The role of the evaluator in decision making is also explored. (RAO)

The contraceptive effectiveness of 155 single women between 15 and 25 years of age was found to be significantly and negatively related to a means-end problem-solving ability and a belief in internal control and significantly and positively related to a belief in chance control. (JMB)

The third in a series of six articles on the use of different models for developing creativity and instructional materials focuses on the sociodrama model. (SBH)

Results showed that play opportunity and training experience for four year olds produced roughly equivalent problem-solving speeds when the task was standard or direct. When the task was nonstandard or innovative, however, play opportunity produced faster problem solving than training. (JMB)

A few examples are discussed of situations where some solution to writing a computer program for an algorithmic problem is immediately evident, but the best solution is some distance away. (MP)

Student errors led to this exploration of the conditions under which log of x base a = x. The discussion requires only techniques contained in a first-year calculus course. (MP)

Two problem-solving strategies involved in finding the area of a particular square formed on a geoboard are described in detail. (MP)

An example is given of a problem-solving approach by outlining the development of a generalization of the Pythagorean Theorem as applied to points on a unit circle. (MP)

A discrimination reversal problem was presented to 192 children varying in age from 3 to 5 years. At the end of both the initial learning and transfer trials, probe trials were introduced to ascertain the response rule describing children's choices. (Author/SB)

Presents us with two monks on a rickety bridge. What the monks, the author, and we readers do with that dilemma is the topic of a brief existential article that contains provocative views on how our heads affect our lives. (Editor)

Competency tests may be invalid because people have different kinds of problems. In addition, these tests do not measure the competency of people who solve problems in unorthodox ways. (LS)

A total of 82 fourth and fifth graders participated in a 15-week intervention program during which they confronted problems requiring formal operational thought. Subjects showed advancement toward formal operations on the pendulum and chemicals problems (Inhelder and Piaget) and on a third problem on immediate and 4-month posttests. (Author/JH)

Advocates communicating the conventional wisdom about teaching to researchers so we can reduce the amount of trivial research that is conducted. (HOD)
