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. (MAZ)

Describes a software library developed to teach biophysics and physiology undergraduates that includes software on (1) the Hodgkin-Huxley model for excitation of action potentials in electrically excitable cells; (2) a random-walk model of diffusion; (3) single voltage-gated ion channels; (4) steady-state chemically mediated transport; and (5)…

Argues that the method of "collaborative modelling" developed to teach reading skills may be utilized in generating and assessing pupil talk within the classroom. Pupil pairs were given different texts from science, English, and geography and asked to re-present them in another form. Results indicate the value of the talk emerging from…

Within mathematics education, classroom teachers, educational researchers, and instructional designers share the common goals of understanding and improving the teaching and learning of mathematics. Teachers work to help students learn; researchers study how people learn and teach mathematics; and designers develop instructional materials to…

The Houston Community College (HCC) 2011-2012 Fact Book provides statistical information about the college district. It is important for the reader to be aware that data presented in this publication may differ slightly from statistics found in other district reports. Such variances may result from differences methodology including the source of…

This document presents text and graphs to provide an overview of administrative expenditures in institutions of higher education in Texas. Administrative expenditure indicators at Texas public senior universities are compared with each other, with national averages, and with averages of the 10 states nearest Texas in population. In constant…

In statistical terms, transfer rates require two components: a numerator that represents community college students who transfer and a denominator that approximates the pool of potential transfer students. The California Task Force adopted a set of criteria to judge the appropriateness of prospective pairs of numerators and denominators. Its form…

In 1992, a study was conducted at Golden West College (GWC) in California to determine whether an English prerequisite should be required for a speech communication course and, if so, what level of English course was necessary. Fourteen sections of Speech Communication 100 were randomly chosen from the spring, summer, and fall semesters during the…
