There are the only two studies available on the types of solutions--unsaturated, saturated, supersaturated, dilute and concentrate--in the related literature with respect to students' understanding. But, no study focuses on remediation of students' alternative conceptions with regard to the aforementioned concepts, based on the assumption that…

This article is the third in a series on the teaching of sets and some of the reasons for doing so. A discussion is presented of the use of set language in teaching concepts from logic, probability and algebra. (JP)

A study was conducted among 64 students in an introductory psychology class at Yale University to clarify the components of syllogistic reasoning used in a syllogistic evaluation task. A modified form of componential analysis was used to decompose the syllogistic evaluation task with abstract content into the subtasks of encoding and encoding plus…

This study was concerned with distinguishing between two kinds of immature reasoning, both of which lead children to draw the same conclusions from arguments and which, therefore, cannot be distinguished by the usual tests. A total of 20 second-graders and 16 sixth-graders were tested on a logic game in which winning depended on drawing correct…

The ideas in this workbook for stimulating children's creative thinking are presented as integral parts of ten stories about a boy named Dudley Bond (a distant relative of a very famous spy), his friend Max (a professional bear), and his cousin Maybelle. They find their imaginations stretched by a backyard scientist-inventor who knows dozens of…

Children from kindergarten, second, and fifth grade were verbally presented a passage containing an equal number of idea units which were relevant versus irrelevant to the main theme of a story. For all grade levels, relevant idea units were recalled to a greater extent than idea units irrelevant to the main theme. (CS)

The purposes of this study were twofold: (1) to investigate the effect of movement for several inanimate objects on children's judgments of "aliveness;" and (2) to examine the nature of explanations given by three age groups of children in support of their judgments as to whether animate and inanimate objects were "alive" or…

An Intelligent Computer Aided Instruction (ICAI) program that incorporates an Expert module which allows the tutor to compare the student's response to those generated by an expert was developed for use with Wumpus, a simple maze-exploration game. The Wumpus Advisor program offers advice to a player involved in choosing the best move in a game for…

The logical foundations of deduction and induction are outlined to form the rules for the construction of a set of tests of reasoning ability. Both deduction and induction involve the derivation of a conclusion from a set of premises. Deductive logic uses syllogisms and is abstract. Inductive logic is both empirical and abstract. Although…

This study was designed to examine the processes underlying developmental changes in children's (1) use of combinatorial strategy, and (2) comprehension of conjunctive and disjunctive propositional relationships. A total of 108 children from third, sixth and eighth grades participated in this study. Each child was administered three tasks…

In common law legal systems, the doctrine of precedent directs appellate judges to search out legal rules articulated in previous cases similar to the present case before making their decision. Although this principle is universally accepted, the extent to which legal rules determine decisions varies, since the rule element and judicial discretion…
