A variety of measures have been developed to quantify intervention effects for single-case experimental design studies. Within the family of non-overlap indices, the Tau-U measure is one of the most popular indices. There are several Tau-U variants, each one calculated differently. The appropriateness of each Tau-U variant depends upon the data…

As one of the core skills of the 21st century, computational thinking has received increasing attention from educators and researchers. Although some research has been conducted on computational thinking, few studies examined the impact of learning activities on students' computation thinking skills from the perspective of cognitive development.…

When undertaking quantitative hypothesis testing, social researchers need to decide whether the data with which they are working is suitable for parametric analyses to be used. When considering the relevant assumptions they can examine graphs and summary statistics but the decision making process is subjective and must also take into account the…

Linda Miller describes a model for the practical implementation of behaviour supports. This model, the "5P approach", attempts to delineate a comprehensive and sequentially-stepped model of the assessment and treatment of challenging behaviour with consistent colour-coded themes. The 5Ps include profiling the child, prioritising the challenging…

Students are frequently unaware that they hold the power of learning in their own hands. Their ability to figure out what they are doing and where they are heading are crucial keys to consciously applying learning strategies, developing effective work habits, and assessing their own performance. The ability to regulate one's own learning means…

Purpose: Under the Individuals With Disabilities Education Act (IDEA; as amended, 2004), speech-language pathology services may be either special education or a related service. Given the absence of guidance documents or research on this issue, the purposes of this clinical exchange are to (a) present and analyze the IDEA definitions related to…

This article re-examines the much maligned piechart and provides justification for its use. It identifies common pitfalls when drawing piecharts in Microsoft Excel and offers advice on how to avoid them. (Contains 6 figures and 5 tables.)

Purpose: The purpose of this paper is to compare the effect of different representations while teaching basic algorithmic concepts to novice programmers. Design/methodology/approach: A learning activity was designed and mediated with two conceptually different learning environments, each one used by a different group. The first group used the…

CADMOS is a graphical learning design (LD) authoring tool that helps a teacher design a unit of learning in two layers: (i) the conceptual layer, which seems like a concept map and contains the learning activities with their associated learning resources and (ii) the flow layer, which contains the orchestration of these activities. One of CADMOS'…

This article reviews and discusses the use of statistical concepts in a natural resources and life sciences journal on the basis of a census of the articles published in a recent issue of the "Agronomy Journal" and presents a flow chart and a graph that display the inter-relationships between the most commonly used statistical terms. It also…

Purpose: This study aims to present a general conceptual framework which can be used to evaluate quality and institutional performance in higher education. Design/methodology/approach: The quality of higher education is at the heart of the setting up of the European Higher Education Area. Strategic management is widely used in higher education…

Sfard and Kieran [Kieran, C., Educational Studies in Mathematics 46, 2001, 187-228; Sfard, A., Educational Studies in Mathematics 46, 2001, 13-57; Sfard, A. and Kieran, C., Mind, Culture, and Activity 8, 2001, 42-76] have developed a methodological framework, which aims at characterizing the students' mathematical discourses while they are working…

This report summarizes the findings of the Computer-Aided Transcription (CAT) Project, which conducted a 14-month study of the technology and use of computer systems for translating into English the shorthand notes taken by court reporters on stenotype machines. Included are the state of the art of CAT at the end of 1980 and anticipated future…

Two small studies, one an "eye-tracking" study and the other a "remote observation" study, have been conducted to investigate ways to identify two kinds of online learner interactions: users flicking through the web pages in "browsing" action, and users engaging with the content of a page in "learning"…

The purpose of this research effort was to develop and evaluate a prototype system-independent Programming Design Guide (PDG) for one of the 13 offline job aids previously developed for use with the Instructional Systems Development (ISD) model. This PDG is intended to provide all of the guidance necessary for a user to implement the job aid on…
