This paper, the first of a two-part article, follows the trail in history of the development of a graphical representation of the complex roots of a function. Root calculation and root representation are traced through millennia, including the development of the notion of complex numbers and subsequent graphical representation thereof. The…

Teaching students to collect data to answer questions is an important life skill that will serve them well throughout their adult lives. The purpose of this manuscript is to describe the implementation of an action research project in a fifth grade resource classroom. Students with mild disabilities were taught how to conduct surveys using three…

Although behavior analysis relies primarily on visual inspection for interpreting data, previous research shows that the method of display can influence the judgments. In the current study, 26 Board-Certified Behavior Analysts reviewed two data sets displayed on each of three methods--equal-interval graphs, tables, and Standard Celeration…

This study examined the fractional graph area (FGA), the proportion of page space used to display statistical graphics, in 11 behavioral journals and places behavior analysis on a continuum with other natural, mathematical, and social science disciplines. The composite FGA of all 11 journals puts behavior analysis within the range of the social…

The universities and faculties which educate teachers of mathematics for teaching pupils/students of any age group from pre-school age to higher education carefully monitor and compare valuable results of this research, detect the areas in which the mathematical achievements of pupils should be improved at the national level and propose the ways…

This paper provides qualitative student-centered research from an online Research Methodology course taught partly within the immersive, 3-D environment of Second Life with fifty-eight graduate psychology students for the purpose of suggesting a constructivist-based instruction model for immersive environments. A qualitative method approach was…

The report describes the development and evaluation of an instructional program in tangible graph interpretation for braille readers. Because graphs frequently appear in textbooks and in other printed sources, lack of appropriate translation for blind persons can be a significant educational obstacle. Based on anlyses of typical graph reading…

Analyzes the commercial energy statistics of the world by dividing the nations into three groups: developed market economy, developed planned economy, and developing nations. (GS)

Experimentation with graphical methods for data presentation is important for improving graphical communication in science. Several graphical methods are discussed including full scale breaks, dot charts, and multibased logging. Full scale breaks are suggested as replacements for partial scale breaks since partial scale breaks can fail to provide…

Presented at the International Seminar on Experimental Research in Music Education (Reading, England, 1968). The full report will be published in "Journal of Research in Music Education, Summer 1969.

The Interaction Sequence Graph records the occurrence of events according to Flanders' 10 categories of verbal interaction, the duration of each behavioral event, and the relationship of each event to those which precede and follow it. Data obtained by observing classroom teaching are analyzed and converted from a long series of numbers to a…

Text and graphs describe the Dynamic Range Configuration audiogram developed at the Central Institute for the Deaf in St. Louis, Missouri. The audiogram displays the portion of the average speech spectrum audible to the child, with and without amplification, and can be effective in counseling parents and planning appropriate amplification.…

An expense account book report encourages students to be creative and doesn't penalize students with reading and writing disabilities. Pie graphs showing expenditures a character from a book might make reveal divergent thinking skills and with a minimum of words. A reproducible worksheet is included. (MT)

Graphical perception is the visual decoding of the quantitative and qualitative information encoded on graphs. Some recent theoretical/experimental investigations of graphical perception are described, identifying certain elementary graphical-perception tasks that are performed in the visual decoding of quantitative information from graphs.…

Discusses the construction of logarithmic and arithmetic scales illustrates why they should be used, and demonstrates the difference between them. Offers suggestions for classroom applications of the scales. (FL)
