Reports two small-scale studies that investigate whether the understanding of scientific concepts will be enhanced by using collaborative pairings. Examines how types of pairings affects performance. Finds students working in pairs outperformed their counterparts working individually. Also notes that dyads improved upon initial performance in…

Compares reading performance of good and poor Brazilian fourth-grade students with Scottish children of equivalent reading competence and age range. Finds that in contrast to the Scottish sample, no cases of predominant morphemic dyslexia or ambiguous cases were found among the Brazilians. Concludes data do not support the view that phonological…

Reviews relationship of IQ scores to race and gender. Explores the logic that supports the use of intelligence testing to discriminate and to exclude. Argues that default assumptions allow researchers to remain unaware of the subtle adverse impact of their research. Includes recommendations to encourage a broader understanding of intelligence.…

Describes psychometric issues associated with three different learning styles models (visual, auditory, and haptic), and the instruments designed to assess those models. Presents some background to the learning styles idea along with suggestions for utilizing this information with developmental students. The learning styles instruments discussed…

Investigated the role of behavioral style and cognitive performance as predictors of cognitive development in extremely low-birth-weight children assessed at age 2 and again at age 4. Found stability of cognitive performance from 2 to 4 years of age; this as well as behavior style and orientation-engagement predicted subsequent cognitive…

Simple arithmetic word problems are often featured in elementary school education. One type of problem, "compare with unknown reference set," ranks among the most difficult to solve. Differences in item difficulty for compare problems with unknown reference set are observed depending on the direction of the relational statement (more than vs. less…

In this study we investigated the putative role of cognitive dysfunction, diagnosis (schizoaffective versus schizophrenia disorder), and alcoholism as risk factors for suicidal behavior among individuals with DSM-IV schizophrenia or schizoaffective disorders. Subjects received cognitive tests and medical records were reviewed for evidence of a…

The study was carried out with 175 Turkish students by using drawings at different ages understanding of gene, DNA and chromosome concepts. Students from 8th, 9th, 11th grades and, science and biology student teachers were simply asked to draw the structure of gene, DNA and chromosome in a cell and also to give explanations about these three…

The purpose of this research study is to explore year 6, 8 & 11 (13, 15 and 17 years old respectively) Turkish pupils' views about the particulate nature of matter within the context of phase changes. About 300 pupils participated in the study. Questionnaires distributed to year 6, 8 and 11 pupils included 6-item open-ended questions about (a)…

Precise and accurate pedon descriptions prepared by field scientists using standard techniques with defined terminology and methodology are essential in describing soil pedons. The accuracy of field measurements generally are defined in terms of how well they agree with objective criteria (e.g., laboratory analysis), such as mechanical analysis…

Neuropsychological tests have limited sensitivity in identifying subtle residual cognitive impairments in patients with good medical recovery from head injury and post-concussive syndrome. Detecting and characterizing residual "real life" cognitive difficulties can be problematic for treatment purposes. This study investigated the usefulness of a…

The purpose of this study was to compare the effectiveness of the Raven's Standard Progressive Matrices, the Naglieri Nonverbal Abilities Test (NNAT), and the Iowa Test of Basic Skills (ITBS) in selecting for ethnically diverse students who may be gifted. The participants of the study were 175 students enrolled in Grades 3-5 and Grade 8 in a…

A study examining the effects of computer animation exercises on cognitive development asked two groups of seventh graders to create computer animations, working from a simple mythic text. The ability of students to create narrative scenarios from this mythic text was analyzed. These scenarios were then recreated in the school computer lab, using…

In 1991, a study was conducted using the Watson-Glaser Critical Thinking Appraisal (CTA) to determine how well students at Rancho Santiago College (RSC), a large, multicultural community institution in Santa Ana, California, demonstrated critical thinking abilities. Written at the ninth grade reading level, the CTA attempts to assess an…

This document provides specific examples of what is involved in applying intellectual criteria and standards to students' reasoning, focusing on elements of reasoning (EORs). The significance of reasoning having elements and the need for standards in assessing reasoning are described. The following are the EORs: (1) purpose, goal, or end in view…
