Instructional designers make numerous decisions daily to perform their job, for example, what authoring tool to use, what model or strategy to use, and what design process to use to develop learning solutions. Decision-making is important in the field of instructional design. The literature revealed many factors or variables instructional…

In this article, the authors focus on five instructional approaches with a strong evidence base for the teaching and learning of math: (a) plan, model, and practice: systematic and explicit instruction; (b) focus on the language of math; (c) use multiple representations, including number lines; (d) build fluency; and (e) provide word problem…

Iteration and improvement are important attributes of design, tacitly indicating that failure is also a part of the process. There are different conceptions of failure in engineering contexts than in other academic settings. Therefore, for beginning designers, these failure experiences may be perceived as mishaps, lowering confidence or interest.…

Visual analysis and nonoverlap-based effect sizes are predominantly used in analyzing single case experimental designs (SCEDs). Although they are popular analytical methods for SCEDs, they have certain limitations. In this study, a new effect size calculation model for SCEDs, named performance criteria-based effect size (PCES), is proposed…

The four-component instructional design model (4C/ID) has been increasingly used in face-to-face and online learning environments. We present a meta-analysis on the use and effect on performance of educational programs developed with the 4C/ID model after more than 20 years of its application and research in different academic areas and technical…

When instructional designers talk about what they do, they often discuss their outcomes rather than their process. Conjecturing during decision-making requires the instructional designer to build upon their prior knowledge of the situation and experiences and make assumptions based on available information to design an appropriate solution. This…

Intelligent tutoring systems are effective for improving students' learning outcomes (Pane et al. 2013; Koedinger and Anderson, "International Journal of Artificial Intelligence in Education," 8, 1-14, 1997; Bowen et al. "Journal of Policy Analysis and Management," 1, 94-111 2013). However, constructing tutoring systems that…

From a philosophical viewpoint, technological design is about connecting what is desirable with what is technically possible. Technology itself plays a major role in design processes, not only because technology development is what designing is all about, but also since the existing technology at any given point in time frames what is possible to…

Within the context of fashion design, fabric is the key variable in the design process, offering infinite options in terms of variety, quality, weight, colour, texture and pattern. The manipulation of these fabrics is an effective tool at the designer's disposal, which can be used to create innovation in a design. This study examines the use of…

Evaluating novelty in design education is subjective and generally depends on expert's referential metrics. Presently, practitioners in this field perform subjective evaluation of answers of prospective students, but many a time, humans are prone to errors when associated with repetitive tasks on large-scale. Therefore, this paper attempts to…

A precisely formulated research question is becoming increasingly important within the humanities. This applies not only to research funding applications, but also to articles, papers, and student theses. This article presents a tool allowing students to develop research questions on their own, which is open enough to allow for a wide variety of…

Several branches of the potential outcome causal inference literature have discussed the merits of blocking versus complete randomization. Some have concluded it can never hurt the precision of estimates, and some have concluded it can hurt. In this article, we reconcile these apparently conflicting views, give a more thorough discussion of what…

In single-case research designs (SCDs) to determine a functional relation a time-series graph is constructed. Preliminary evidence suggest the approach used to scale the vertical axis and the data points per x- to y-axis ratio (DPPXYR) impact visual analysts' decisions. We conducted a systematic review to evaluate time-series graphs published in…

This dissertation was designed to foster a deeper understanding of population invariance in the context of composite-score equating and provide practitioners with guidelines for addressing score equity concerns at the composite score level. The purpose of this dissertation was threefold. The first was to compare different composite equating…

The rapid development of technology in today's times make business' survival a rather complex task. It is therefore necessary for the specialized organization and administration of each company to differentiate and strengthen its competitive advantages. Gamification is an established practice in many business domains and can enforce employees to…
