Observation of patterns constructed on geoboards can lead to discussions of properties of primes, number sequences, and complex numbers. (SD)

This paper reports two experiments investigating the effect of schooling and urbanization on short term recall and recognition memory. Subjects were 384 male children and young adults living in Morocco representing urban and rural and schooled and nonschooled backgrounds. Additional subject groups--including Koranic school students, Moroccan rug…

Described are three experiments which probed children's sensitivity to structure or organization in visual patterns. Each experiment employed a different paradigm (complexity judgment, discrimination learning, recognition learning, and memory) in order to tap different aspects of children's use of structural information. Subjects were children in…

To combat difficulties of dictated spelling tests, such as unreliable scoring due to illegible writing and the possibility of clues being provided through the enunciation of words by examiners, a technique was developed for writing experimental spelling tests by computer. Additionally, the diagnostic function of spelling scales was considered…

Processing complex multivariate information effectively when relational properties of information sub-groups are ambiguous is difficult for man and man-machine systems. However, the information processing task is made easier through code study, cybernetic planning, and accurate display mechanisms. An exploratory laboratory study designed for the…

The first of two experiments conducted in Detroit investigated the relationship between class and ethnic membership and identification of class and ethnicity; the role age and sex of respondent play in accuracy of speaker identification; and attitudes toward various socioethnic speech patterns. The second study was concerned with the attitudes of…

Three experiments compared cognitive processes in Caucasian nursery school children from different socioeconomic backgrounds who were equated for performance on the Peabody Picture Vocabulary Test. The first demonstrated that children from lower socioeconomic backgrounds experience more difficulty in solving a series of extradimensional and…

An activity is presented which provides an opportunity for students to discover numerical patterns with the aid of a calculator. (MN)

Described are: how teachers can use the computer language Logo, along with noncomputer activities, for teaching about linear and two-dimensional patterns and about combining shapes to create more complex shapes. Three computer program listings are included. (MNS)

Suggestions are given on how to introduce calculators in the primary grades plus activities to teach number concepts and number patterns. (MNS)

Provided are follow-up activities for having students explore the concept of line symmetry. Using a mirror to move a pattern; finding patterns with one, two, or four lines of symmetry; finding asymmetrical patterns; deciding if patterns are different; and solving the problem of finding all patterns possible are discussed. (MNS)

Two quasiexperimental designs--nonequivalent dependent variable and reversed treatment designs--illustrate pattern matching logic as a basis for evaluation, examining college health services. Three pattern matches are significant: (1) program pattern match indicates implementation; (2) measurement match assesses test validity; and (3) effect…

The problem-solving skills of logical thinking, critical thinking, visualization, and communication skills are linked with some activities for students. Sample activities with logic, strategies and patterns, breaking fixed notions, open-minded problems, spatial visualization, and communication are described. (MNS)

A total of 72 children, 36 each from first and sixth grades, were given a 70-item study list followed by a recognition test list of equal length. To indicate the relative dominance of features encoded at both ages, labels, pictures, and referents were recombined to form visual, semantic and acoustic distractors. (MS)

In an investigation of how different types of topic reinstatements affected second language learners' recognition and recall of sentence topics in lectures, it was learned that repeated structures were more easily recalled and recognized than simple ones, and low English proficiency learners have poorer recall of complex structures.
