The power of mathematical inscriptions, such as graphs, is often attributed to the fact that they summarize a lot of information independent of their contextual particulars. There is evidence, however, that even quintessential experts and scientists have difficulties interpreting graphs when they are unfamiliar with the entities represented and…

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…

What is physics without graphs and diagrams? The web is becoming ubiquitous, but how can one expect students to make graphs and diagrams on the web? The solution is to extend functionality through Java applets. Four examples of exercises using the Physics Applets for Drawing (PADs) will illustrate how these can be used for physics instruction to…

This article describes the use of limits in topics that are usually covered in a high school advanced placement chemistry course or a first-year college chemistry course. Such an approach supplements the interpretation of the graph of an equation since it is usually easier to evaluate the limit of a function than to generate its graph. In…

This article takes a further look at the percentage of data points exceeding the median (PEM) analysis method for single-case research data, first presented in this journal by Hsen-Hsing Ma. Ma examined the relationship between PEM and the established percentage of nonoverlapping data (PND) and then applied PEM in a meta-analysis of 61 data sets,…

This paper examines the relation between bodily actions, artifact-mediated activities, and semiotic processes that students experience while producing and interpreting graphs of two-dimensional motion in the plane. We designed a technology-based setting that enabled students to engage in embodied semiotic activities and experience two modes of…

Previous visual analysis research reported that the overall agreement between visual analysis and statistical analysis was poor. In response, some researchers suggested the use of celeration lines to improve the accuracy and reliability of visual analysis. However, subsequent research reported little or no improvement in accuracy with such lines.…

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.
