Computer science is a dynamic field of study that requires constant review and updating of the curricular designs in academic programs--in general, measuring the impact of plan changes has been little explored in the literature. In most cases, it focuses only on structuring its curricula, leaving aside several factors associated with important…

The purpose of this qualitative design case study was to determine the design elements that can lead to technology acceptance of a mobile multimedia tour at an informal historical site. Using rapid prototyping, a tour prototype was developed using a low-cost Website building platform. The tour was then tested with thirteen participants in two…

Online instructional design and how to engage students cognitively in online asynchronous courses have been an ongoing question. This case study presents an intentional design of an asynchronous online graduate course to foster cognitive presence. The research questions investigate students' cognitive presence (CP) captured by two measures:…

Qualitative and multimethod scholars face a wide and often confusing array of alternatives for case selection using the results of a prior regression analysis. Methodologists have recommended alternatives including selection of typical cases, deviant cases, extreme cases on the independent variable, extreme cases on the dependent variable,…

Nontraditional adult students in higher education must balance a multitude of responsibilities while completing their college education. This student population juggles work, family, and college coursework. To maximize options for this student population and meet their needs, institutions of higher education have developed alternative modes of…

The central roles of science in the field of remedial and special education are to (a) identify basic laws of nature and (b) apply those laws in the design of practices that achieve socially valued outcomes. The scientific process is designed to allow demonstration of specific (typically positive) outcomes, and to assist in the attribution of…

This study examined how specific guidelines and heuristics have been used to identify methodological rigor associated with single-case research designs based on quality indicators developed by Horner et al. Specifically, this article describes how literature reviews have applied Horner et al.'s quality indicators and evidence-based criteria.…

Multisite trials, in which individuals are randomly assigned to alternative treatment arms within sites, offer an excellent opportunity to estimate the cross-site average effect of treatment assignment (intent to treat or ITT) "and" the amount by which this impact varies across sites. Although both of these statistics are substantively…

Purpose: The purpose of this paper is to examine relationship between teacher competences and organizational citizenship behavior (OCB) with empowerment as a mediating factor. Design/methodology/approach: The study took a cross-sectional descriptive and analytical design. Using cluster and random sampling procedures, data were obtained from 383…

Researchers have become increasingly interested in programs' main and interaction effects of two variables (A and B, e.g., two treatment variables or one treatment variable and one moderator) on outcomes. A challenge for estimating main and interaction effects is to eliminate selection bias across A-by-B groups. I introduce Rubin's causal model to…

The purpose of this article is to demonstrate how hierarchical linear modeling (HLM) can be used to enhance visual analysis of single-case research (SCR) designs. First, the authors demonstrated the use of growth modeling via HLM to augment visual analysis of a sophisticated single-case study. Data were used from a delayed multiple baseline…

This meta-analysis used hierarchical linear modeling to examine 115 single-case studies with 343 participants that examined the effectiveness of social skills interventions for individuals with autism spectrum disorder (ASD). The average effect size of the included studies was 1.40 (SD = 0.43, 95% CL = 1.32-1.48, N = 115). In the further, several…

This article examines peer-to-peer learning--in virtual schools--among the most vulnerable of students. As a description of a comprehensive case study focused on three different students with disabilities, their parents, their teachers, and their school administrators, this article examines the effects of three kinds of variables on the prevalence…

The aim of this research was to design a framework for integrating e-learning in Higher Education Institutions in developing countries. Data were collected from 266 university students and staff of five universities in Uganda using a questionnaire. Data were analyzed using descriptive statistics. The requirements for e-learning integration were…

Children's participation in after-school physical activity can attenuate the overweight and obesity rates among rural, low socioeconomic status (SES) children. Children's individual determination, as well as social and environmental factors, can influence their behaviors. Purpose: The purposes of this study were to determine if a difference…
