Having students find and cut out of graph paper the 12 pentominoes can provide an enjoyable exercise in perception, discovery, and double checking. The pentominoes can then be used to illustrate informally several geometric concepts. (SD)

Four commissurotomy patients were tested for ability to match tachistoscopically presented stimuli with pictures in free vision, according to either structural appearance or functional/conceptual category. (Editor)

Presents several examples of investigations which demonstrate the following: (1) algebra is connected to other mathematical topics; (2) algebra is an effective tool for representing patterns and relationships; and (3) algebra is an effective tool for analyzing patterns. (DDR)

This sixth in a series of edited transcripts based on a conference at Utah State University discusses ideas from cognitive psychology that have implications for instructional design. Highlights include information processing phases; pattern recognition; short-term and long-term memory; purposes of instruction; cognitive structures; and cognitive…

Developing numerical relationships with calculators is emphasized. Calculators furnish some needed support for students as they investigate the value of fractions as the numerators or denominators change. An example with Logo programing for computers is also included. (MNS)

Several experiments were undertaken with a total of 111 undergraduates. Subjects attempted to imagine how three-dimensional novel wire objects would appear from viewpoints other than that of the subject. Subjects were unable to perform this task without making use of strategies that circumvent the process of visualization. (TJH)

In three experiments, three normal preschoolers were presented with sorting tasks ordinarily insoluble for four-year-olds. Found that, although the subjects had difficulty correctly sorting the pictures when told what criterion to sort by, they could provide correct answers when asked what they were looking for. This self-instructional effect was…

Introduces students to nonperiodic tiling and allows them to construct their own sets of kites and darts through a series of explorations, conjectures, and discoveries. (ASK)

Argues that mathematics is, to a large extent, the study of patterns. Presents an activity in which students search for patterns in the Fibonacci sequence and Pascal's Triangle. (ASK)

Self-reflection, typically operationalized in scales of egocentrism and introspectiveness, is portrayed as problematic in much of the literature on adolescents. Self-reflection has been linked to dysfunctional self-consciousness, symptomatology, and risk behaviors. Yet, self-reflection also is seen as essential for adolescent development,…

We have used multiple sources to identify a population-representative cohort of newly diagnosed patients with parkinsonism and Parkinson's disease in the UK over a 2-year period. All patients have been invited to participate in a detailed clinical assessment either at home or in an outpatient clinic. These assessments have been used to refine…

Children with dyslexia are believed to have very poor phonological skills for which they compensate, to some extent, through relatively well-developed knowledge of letter patterns. We tested this view in Study 1 by comparing 25 dyslexic children and 25 younger normal children, chosen so that both groups performed, on average, at a second-grade…

Over the past few years evidence-based practice has become of central concern to health and social services in this country. The fundamental tenant is that there must be a clear link between professional practice and its research base. This paper outlines the concept of evidence-based practice and how it rests on the concept of good quality…

Pattern work is now undertaken as early as kindergarten, and both researchers and teachers have discovered that children engage in pattern work with great enthusiasm and innate ability. Having some flexibility in pattern perception and selecting mathematically useful patterns require some training, although there is nothing particularly algebraic…

A project was conducted at Reading Area Community College (Pennsylvania) to develop the basic reading, writing, and mathematics skills of students with learning disabilities, to develop the self-esteem of these students, to motivate them, and to develop a model program that could be used by other adult education providers. The project featured a…
