The importance of computational skill for answering items in the quantitative thinking subtest of the Iowa Tests of Educational Development was investigated. Results show that computational skill is not a major factor contributing to the examinee's score on the subtest. (Author/GK)

Studied adults (ages 20-79) presented with two types of problem-solving tasks: a typical task used in problem-solving research, and a task composed of practical daily life problems. Results indicated that developmental function depends on the type of problem presented, while performance on abstract problems may decrease with age. (Author)

Examined the relationship between social adjustment and problem solving skills in samples of popular, aggressive, and isolated boys. Popular boys generated more problem solutions than the other groups. Data showed deviant boys are deficient in generating solutions but not in evaluations of presented solutions. (Author/RC)

It is proposed that the various classes of a priori knowledge incorporated in heuristic reasoning processes exert a strong influence over architectural design activity. Some design problems require exercise of some provisional set of rules, inference, or plausible strategy which requires heuristic reasoning. A case study illustrates this concept.…

The introduction of computer use in college mathematics classes for non-mathematics oriented students majoring in marketing, management, and other business-related fields is discussed. Results of a questionnaire of student opinions matched with pupil course grades is presented. It is noted students as a whole seemed satisfied with computer use.…

A possible logical flaw based on similar triangles is discussed with the Sherlock Holmes mystery, "The Muskgrave Ritual." The possible flaw has to do with the need for two trees to have equal growth rates over a 250-year period in order for the solution presented to work. (MP)

A lesson on a basic logarithmic property is presented, using geometric representations and limits of sequences. (MP)

A program which offers the principal advantages of individualized problem sequences and interactive remedial assistance, and runs in a format that allows one machine to serve more students than the common types of computer-based exercises, is described. Copies of the program listing are available from the creator. (MP)

Examined the relationship between the social and task dimensions of small groups. Developed a measure of group members' feelings of cohesion. Demonstrated that perceptions about the quality of group interactions, goal attainment, group satisfaction, and group solidarity are significantly and positively related. (RC)

Two kinds of secret writing, codes and ciphers, are discussed. The weakness of a ciphering system mentioned in the March 1981 issue is pointed out, and an alternate method is presented. Programs written in BASIC are presented which can be used to encipher messages and help break ciphers. (MP)

Teacher education programs have long attempted to teach students to follow a rational mode of thinking. Recent research on teacher thinking has shown that a gap exists between how teachers think and the rational model. Such research should be used to give teacher educators insight into how their students think and learn. (JN)

A paradigm is presented on administrative decision-making processes. The paradigm includes the possibility of developing a new policy as part of the problem- solving process. (JN)

A series of well-defined steps is given for solving titrimetric problems, based on the mole concept. An example is given, including calculations from the first step to the last. (SA)

Presents responses to an earlier report concerning a procedure for the derivation of the Ideal Gas Law from Charles', Boyle's, and other gas laws. Logic errors and solutions that work are discussed. (CS)

Reports on a marriage preparation program using a small discussion-group format and pre- and postwedding sessions, emphasizing communication patterns and conflict resolution. Evaluation shows that spouses in such a program are less likely to engage in destructive conflict with each other, and that spouses would seek assistance in solving problems.…
