The failure of many instructional design initiatives is often attributed to poor instructional design. Current instructional design models do not provide much insight into design processes for creating e-learning instructional solutions. Given the similarities between the fields of instructional design and software engineering, instructional…

Evaluation of the cosine function is done via a simple Cordic-like algorithm, together with a package for handling arbitrary-precision arithmetic in the computer program Matlab. Approximations to the cosine function having hundreds of correct decimals are presented with a discussion around errors and implementation.

We propose the use of a laptop with a program generator and a transistor power amplifier to control the frequency, duration and amplitude of the LED stroboscope flashes. Examples of the stroboscopic photographs are given.

Mplus is a powerful latent variable modeling software program that has become an increasingly popular choice for fitting complex item response theory models. In this short note, we demonstrate that the two-parameter logistic testlet model can be estimated as a constrained bifactor model in Mplus with three estimators encompassing limited- and…

This article reminds readers of the benefits that use cases bring to the software development process. Use cases, as featured in the UML (Unified Modeling Language), are contrasted with the much terser "user stories" favoured by agile methods. With their normal and alternative flows, and extending and included behaviours, use cases…

In this report, we introduce a system for running reimbursed surveys via text messages and mobile cash. The key advantage of this approach is the ability to conduct rapid surveys at an extremely low cost. After reviewing existing literature, we describe an automated system for conducting such surveys and demonstrate its merits in a…

Gamification is the use of game design elements in nongame contexts and has been shown to be effective in motivating behavior change. By seeing game elements as "motivational affordances," and formalizing the relationship between these elements and motivational affordances, it is the position of this article that gamification can be…

This study strived to determine the effectiveness of integrative teaching of reading strategies and working memory on basic math and problem-solving skills. It is a quasi-experimental pretest-posttest study carried out on 50 second-graders from Chahashk Shandiz village in the academic year of 2020-2021 who were randomly selected by cluster…

As we enter a new age of technological innovation and subsequent educational instrumentation change, there is increasing demand for innovative methods that encourage student learning experiences in virtual, online spaces. ePortfolios and e-book projects are designed and owned by students and are centered within the student's learning. They provide…

This study examined the effects of reflective practices (RP) on self-directed learning competencies (SDLC) as well as the relationship between technology-mediated collaborative learning (TMCL) as a reflective practice and SDLC in a preservice teachers' class. Regression analyses were conducted to examine the effects of RP on SDLC. In addition, a…

Programmatic advertising has come to dominate the landscape of digital media planning. To prepare ad majors for their future careers in the industry, it is essential to teach students programmatic buying and provide them with hands-on experience. In this article, the authors present their approach of integrating teaching programmatic buying into a…

This article reports the results of an explorative, quantitative study designed to investigate the pedagogical potential of Flip (formerly Flipgrid) as a connectivist and transmedia tool for developing English language learners' productive skills to provide a basis for their continued improvement. The study suggests that the connectivist practice…

Mobile technologies illustrate a positive effect when used in mathematics learning. However, user experience evaluations are mostly quantitative. The study adopted a qualitative case study approach using semi-structured interviews to examine the experiences of educators at a special needs school in the Western Cape, South Africa. Thematic analysis…

Artificial intelligence (AI) tools have become a popular topic in the education field. Most of the schools in Hong Kong focus on how to properly use AI software to help students' learning experience. As this is still a relatively new technology, the stance for most of the schools in Hong Kong is skeptical. This study aims to find out whether…

In recent years, artificial intelligence (AI) has increasingly made advances across various fields, including ELT. In this article we embrace an egalitarian dialogue framework to explore and understand the role of AI in language education. This format provides a useful backdrop for navigating the dual responses--enthusiasm and scepticism--by which…
