Effects of a student with severe emotional/behavioral disorders (SEBD) graphing her own performance data on rate of correct words read per minute were evaluated using a withdrawal of treatment case study design. The student recorded her daily performance using a desktop computer and standard spreadsheet software that automatically graphed each…

Effects of microcomputer-based laboratory (MBL) exercises and level of cognitive development on high school biology students' ability to construct and interpret line graphs were investigated. Forty-six students enrolled in general biology classes at a rural high school volunteered to participate in the study. These students were administered…

In the introductory section of this report, the Second International Mathematics Study (1981-82) is described. The study, which involved about 500 classrooms in the United States and classrooms in 24 other countries in grades 8 and 12, was designed to provide detailed information about the content of the mathematics curriculum, how mathematics is…

Examines (1) how students evaluate information obtained in the science laboratory; (2) the effects of use of microcomputer-based laboratory; and, (3) the effects of explicit instruction on critical evaluation skills. Discusses results in terms of students' propensity to accept incorrect graphs and in terms of the effect of the enhanced instruction…

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)

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)

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…

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…

This article describes an approach to teaching linear equations using multiple representations in a highly motivating context. Connections among representations are made explicit to enhance understanding and empower students. (Contains 4 figures.)

An exploratory study developed ways to describe systematically a particular graphic organizer, the frame. For the study, 27 middle-grade teachers each constructed 2 frames on sections of fourth-grade science and social studies texts. Teachers also worked collaboratively in pairs and larger groups to produce frames. Collaborative sessions were…

This document is a compilation of classroom aids for teachers using statistical data appearing in World Eagle publications. Six teachers and the editors of World Eagle supplied specific examples of materials generated for classroom drills, tests, and assignments. Classroom assignments and documents are designed to teach statistical information…
