We argue that the traditional physical environment is commonly taken for granted and that little consideration has been given to how this affects pupil-teacher interactions. This article presents evidence that certain physical environments do not allow equal visual interaction and, as a result, we derive a set of basic guiding principles that…

In social sciences, the use of stringent methodological approaches is gaining increasing emphasis. Researchers have recognized the limitations of cross-sectional, non-manipulative data in the study of causality. True experimental designs, in contrast, are preferred as they represent rigorous standards for achieving causal flows between variables.…

The concepts of "tradition" and "authority" are generally understood to be problematical in history curriculum design. Drawing on MacIntyre's account of disciplines as social practices, this article argues that, to the contrary, these are concepts that need to be incorporated into any curriculum theory that attempts to build a…

This commentary on the special issue, entitled "Models and Tools for Systems Learning and Instruction," highlights the accomplishments of the papers in this collection. It also points to some avenues for further strengthening research on promoting systems understanding. Collectively, the papers make advances in our understanding of how…

The purpose of this study is to disseminate the results of recent advances in statistical power analyses with regard to multilevel mediation and its implementation in the PowerUp!-Mediator software. The authors first focus on the conceptual and statistical differences among common asymptotic, component-wise, and resampling-based tests of mediation…

The purpose of this paper is to present results of recent advances in power analyses to detect the moderator effects in Cluster Randomized Trials (CRTs). This paper focus on demonstration of the software PowerUp!-Moderator. This paper provides a resource for researchers seeking to design CRTs with adequate power to detect the moderator effects of…

The authors discuss the need for critical thinking that examines the foundations of the field of educational technology. They provide an overview of two activities that can allow this kind of examination to take place. The first focuses on identifying assumptions and evaluating their implications. The second focuses on Finn's ("Audiovisual…

Global companies often face cultural issues when they conduct training of employees in other countries. In today's increasingly global and digitally connected society, it is essential to assure the alignment between the learning needs of individuals from different cultures and the way content is designed and delivered, both online and…

Based on the increasing interest in systematic reviews and meta-analyses of Single-Subject Experimental Designs (SSEDs), the aim of the present review is to determine the general characteristics of these meta-analyses, including design characteristics of the primary studies and the meta-analyses, the kind of data, and the kind of analysis. After a…

Single-case design is a repeated-measures research approach for the study of the effect of an intervention, and its importance is increasingly being recognized in education and psychology. We propose a Bayesian approach for estimating intervention effects in SCD. A Bayesian inference does not rely on large sample theories and thus is particularly…

Instructional developers and others creating apps must choose from a wide variety of app development tools and technologies. Some app development tools have incorporated visual programming features, which enable some drag and drop coding and contextual programming. While those features help novices begin programming with greater ease, questions…

This updated third edition of "Curriculum Planning and Instructional Design for Gifted Learners": (1) Is a guide to designing curriculum for the gifted at any level of learning and in any subject area; (2) Addresses the need to differentiate at all levels in the design process; (3) Shows how to customize curriculum for advanced learners;…

Purpose: This research attempts to reveal ways of addressing challenges in open universities related to empowering lifelong learning; establishing policies and strategies in dropouts, student portfolio and support services for students with special needs; and implementing online instructional design and strategies. Two institutions were…

The use of analytical methods from learning analytics (LA) research combined with visualizations of learning activities using learning design (LD) tools and frameworks has provided important insight into how instructors design for learning. Nonetheless, there are many subtle nuances in instructors' design decisions that might not easily be…

Learning management systems (LMSs) are ubiquitous components of the academic technology experience for learners across a wide variety of instructional contexts. Learners' interactions within an LMS are often contingent upon how instructors architect a module, course, or program of study. Patterns related to these learner interactions, often…
