The current study used a randomized control trial to evaluate a decision-making model on special education preservice candidates' instructional decision-making and self-reported confidence ratings when analyzing graphed student data. Thirty-two special education preservice candidates viewed authentic curriculum-based measurement (CBM) graphs and…

Importance: The article raises a point of visual representation of big data, recently considered to be demanded for many scientific and real-life applications, and analyzes particulars for visualization of multi-dimensional data, giving examples of the visual analytics-related problems. Objectives: The purpose of this paper is to study application…

Programming education has recently received increased attention due to growing demand for programming and information technology skills. However, a lack of teaching materials and human resources presents a major challenge to meeting this demand. One way to compensate for a shortage of trained teachers is to use machine learning techniques to…

This paper outlines the theoretical reasoning and technical implementation of a particular approach to creating multi-layered chronological charts in qualitative biographical studies. The discussed method elucidates the interpretation of traditional life chronologies where the individual's "objective" life facts are reconstructed free from…

Maintaining comparability of test scores is a major challenge faced by testing programs that have almost continuous administrations. Among the potential problems are scale drift and rapid accumulation of errors. Many standard quality control techniques for testing programs, which can effectively detect and address scale drift for small numbers of…

The Reconstructed Cohort Method is often used to examine the status of national education. However, this method does not account for individual details and we know little about the status of school enrolments by tracking individual students from entrance until dropout or graduation. This study employs the True Cohort Method to analyse data for…

The aim of this paper is to study the analysis of contingency tables with one heavyweight column or one heavyweight entry by taxicab correspondence analysis (TCA). Given that the mathematics of TCA is simpler than the mathematics of correspondence analysis (CA), the influence of one heavyweight column on the outputs of TCA is studied explicitly…

The State Higher Education Finance (SHEF) report is produced annually by the State Higher Education Executive Officers (SHEEO) to broaden understanding of the context and consequences of multiple decisions made every year in each of these areas. No single report can provide definitive answers to such broad and fundamental questions of public…

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…

Presents a case study for use in the teaching of bioprocess design. Taking the production and isolation of the intracellular protein s. cerevisae, demonstrates how undergraduates can use a range of data to construct and then investigate the range of processes flowsheet options available for a process duty.

The technique developed in this research paper for analyzing the information in charts and graphs is designed to reveal design flaws in the display that may prevent them from conveying information effectively. This analytic scheme requires isolating four types of constituents in a display and specifying their structure and interrelations at the…

This report consists of seven charts which present data on patterns of parental visiting of children in foster care in New York City from October 1976 through March 1977. Information contained in the charts is derived from the quarterly Child Welfare Information Services (CWIS) reports developed by David Fanshel and John Grundy. The charts present…

This report consists of three charts which present data on adoption patterns in New York City in the year 1976. The report is based on quarterly Child Welfare Information Service (CWIS) reports developed by Dave Fanshel and John Grundy. Each chart is accompanied by a brief explanatory text, and a summary of the findings. The charts present data on…

In this paper, a method for analyzing data from student evaluations of teaching is presented. The first step of the process requires development of a regression model for teacher's summary rating as a function of student's expected grade. Then, two-sigma control charts for individual evaluation scores (section averages) and residuals from the…

This study seeks to understand American Sign Language (ASL) as heterogeneous communication and to use it as a model for developing in other modalities alternative heterogeneous communication systems with the same advantages. (26 references) (CK)
