Describes the "number 2 arithmetic challenge," an activity in which students score points by creating examples using the number 2 that satisfy an unknown rule. Computers are utilized to verify and record examples. Conflicts with computer responses create situations to explore negative numbers, fractions, mixed numbers, the order of…

Sex differences in variability in the national norms of the Differential Aptitude Tests, Preliminary Scholastic Aptitude Test/Scholastic Aptitude Test, Wechsler Adult Intelligence Scales, and California Achievement Tests were examined. Compared to females, males were consistently more variable in quantitative reasoning, spatial visualization,…

Presents the results of a survey of 165 seventh grade students asked to respond yes, no, or maybe to 21 metacognitive statements about their cognitive activity on a mathematical word problem. Suggests how to use the responses as a basis for developing classroom activities. (MDH)

A longitudinal study followed Brian from grade five through grade seven to examine his representation and development of mathematical knowledge. Some observations over the four years were that Brian liked to figure things out, responded poorly to suggestions not fitting the representation he constructed, and changed attitudes from purposeful and…

Asserts that research into the effects of word processing on student writing is dependent on established writing skills, keyboarding techniques, human intervention, and the established criteria for good writing. Concludes that nonnative writers may benefit in significant ways from the attributes of word processing. (CFR)

Presents a scripted lesson plan for intermediate grades, based on M.C. Wittrock's model of generative teaching derived from brain lateralization research. Uses a shopping mall as the setting for hypothetical dilemmas. Offers a combination of verbal and imagined strategies that improve students' economic reasoning and teaches cost-benefit analysis.…

Asserts that economics can be taught more effectively at all grade levels using the whole-language approach. Describes the role of teachers, students, and the instructional process in the whole-language classroom. Discusses student evaluation using portfolios and includes a portfolio description table used in an economics class. (CFR)

Reviews research on interactive computer learning. Examines the extent to which learner-computer interaction and learner-learner interaction can interfere with or support one another. Finds that viewing collaborative learning as joint negotiation of a common problem helps to define optimal characteristics of educational software. (CFR)

Reports on a study of 22 pairs of third-grade students and 22 pairs of seventh-grade students who worked on a variety of computer-based tasks. Finds that older students were more likely to focus on internal pattern construction than remaining oriented toward external characteristics of the patterns. (CFR)

Task engagement and conceptual change were studied for 12 sixth graders in 2 classrooms where teachers and instructional materials provided students with extensive support to understand science better. Results indicate that some students recognize the value of science learning and demonstrate cognitive engagement, whereas others pursue alternative…

This review of the past 10 years of computer-based instruction (CBI) with students having mild disabilities notes constraints (such as unrealistic expectations and limited access to hardware and software), and then considers the impact of CBI on curriculum, teacher training, teacher role and attitudes, instructional design, and learning of basic…

Mel Levine writes about learning disabilities in a way that sometimes invites satire. The premise of his 2003 book, "The Myth of Laziness," for example, is that a child who appears lazy probably does not lack motivation, but rather suffers from "output failure." Levine, a professor of pediatrics at the University of North…

This study evaluated the cognitive and achievement profiles of college students experiencing difficulties in foreign language (FLD group). Because past research appears to have generated different results based on the type of comparison groups utilized, we attempted to obtain a better representation of students with foreign language difficulties.…

Socioeconomic status (SES) is strongly associated with cognitive ability and achievement during childhood and beyond. Little is known about the developmental relationships between SES and specific brain systems or their associated cognitive functions. In this study we assessed neurocognitive functioning of kindergarteners from different…

This study compared sentence comprehension skills in typically developing children 5-17 years of age, children with language impairment (LI) and children with focal brain injuries (FL) acquired in the pre/perinatal period. Participants were asked to process sentences "on-line", choosing the agent in sentences that varied in syntactic complexity…
