Explains graphing functions when using LOTUS 1-2-3. Provides examples and explains keystroke entries needed to make the graphs. Notes up to six functions can be displayed on the same set of axes. (MVL)

Described is a four-month social studies unit allowing for the integration of mathematics and language arts in grade one. The unit focuses on the concept of shelter; mathematics emerges as the key investigative tool used to facilitate and broaden the children's view of where they and their classmates live. (MNS)

Discusses the use of graph theory to aid in the depiction of organic molecular structures. Gives a historical perspective of graph theory and explains graph theory terminology with organic examples. Lists applications of graph theory to current research projects. (ML)

Toddlers in the lowest 10th percentile for lexical production were compared with age- and language-matched controls on measures of phonetic complexity, lexical development, and grammatical complexity. Results indicate an overlap between phonology, lexicon, and grammar and suggest the importance of true consonant production for lexical development.…

Using a video sign-monitoring task in American Sign Language, this study investigated the effects of late exposure to a primary language on adult linguistic processing. Native signers were sensitive to errors in both verb agreement and aspect; early and late signers were only sensitive to errors in aspect morphology. Late exposure was found to…

Presents an analysis of errors in a 400-page corpus of German essays by American college students in second-year language courses showing that syntax is the most problematic area, followed by morphology. This study indicates that 80% of student errors are not of semantic origin and are potentially recognizable by a syntactic parser. (six…

Reports on the reading habits of native-English speaking and nonnative-English speaking undergraduate college students who completed a reading habits questionnaire. Results revealed that nonnative students read more widely for longer periods of time and had higher perceptions of themselves as readers in their native language than did…

Presented are exercises that demonstrate the application of standard concepts in the design of algorithms for plotting certain fractals. The exercises can be used in any course that explains the concepts of bounded or unbounded planar sets and may serve as an application in a course on complex analysis. (KR)

Describes a study of high school students that investigated the use of microcomputers to teach principles relating to the design and interpretation of graphs. Results related to student achievement, higher order thinking skills, and behavioral protocols are discussed. A sample assignment sheet and test questions are appended. (66 references) (LRW)

Two students (ages 10-11) with learning disabilities exhibited improved on-task behavior and academic performance during self-monitoring procedures, with additional increases resulting from self-graphing procedures. However, little improvement in on-task behavior and academic productivity was noted with the introduction of self-reinforcement and…

An integrated unit that combines the areas of science, social studies, and art is described. Water and land environment, the community, and folk arts are reflected in the unit. Activities include measuring water and air parameters, netting and seining, observation of a stream and the land around it, writing and picture journals, and media…

Integrates mathematics and science by investigating the scientific application of the Polynomial Difference Theorem using data points from an experiment. Utilizes the different capabilities of the graphing calculator to investigate a problem whose solution is a second degree equation and makes connections between the mathematical concepts involved…

Describes use studies of CD-ROM products in American and western European academic, public, and special libraries. Comparative results of the surveys are reported, including effect of CD-ROMs on library use of online databases, difficulties with different vendors' search techniques, and desired subjects of optical products. (10 references) (LRW)

Demonstrates how to construct rational, exponential, and sinusoidal functions that appear normal on one scale but exhibit interesting hidden behavior when viewed on another scale. By exploring these examples, students learn the importance of scale, window size, and resolution effects in computer and calculator graphing. (MAZ)

Stresses using the features of graphing calculators to teach parametric equations much earlier in the curriculum than is presently done. Examples using parametric equations to teach slopes and lines in beginning algebra, inverse functions in advanced algebra, the wrapping function, and simulations of physical phenomena are presented.
