Computerized adaptive testing (CAT) enables efficient and flexible measurement of latent constructs. The majority of educational and cognitive measurement constructs are based on dichotomous item response theory (IRT) models. An integral part of developing various components of a CAT system is conducting simulations using both known and empirical…

The likelihood for generalized linear models with covariate measurement error cannot in general be expressed in closed form, which makes maximum likelihood estimation taxing. A popular alternative is regression calibration which is computationally efficient at the cost of inconsistent estimation. We propose an improved regression calibration…

Researchers in the behavioral and social sciences often have expectations that can be expressed in the form of inequality constraints among the parameters of a structural equation model resulting in an informative hypothesis. The questions they would like an answer to are "Is the hypothesis Correct" or "Is the hypothesis…

This article discusses integrated approaches to the management and preservation of born digital photography. It examines the changing practices among photographers, and the needed relationships between the photographers using digital technology and the archivists responsible for acquiring their born digital images. Special consideration is given…

In March 2019, the EdWeek Research Center conducted an online survey of 700 pre-K-12 teachers to learn more about how they experience and perceive ed-tech innovation. Results suggest that K-12 schools, while not innovation deserts, have plenty of room to grow when it comes to meaningful and positive changes to the ways in which they use technology.

This study investigates the effectiveness of teaching pronunciation with instructional software to a cohort of Chinese learners of English aged 13 to 16 at lower-intermediate level. It also explores the relationship between learners' attitudes towards pronunciation and their pronunciation learning. Participants were 60 students at a language…

This paper presents the "Multi-Role Project" method (MRP), a broadly applicable project-based learning method, and describes its implementation and evaluation in the context of a Science, Technology, Engineering, and Mathematics (STEM) course. The MRP method is designed around a meta-principle that considers the project learning activity…

Problem solving in the field of quantitative composition of solutions (QCS), expressed as mass share and molar concentration, is essential for chemistry students. Since successful chemistry education is based on different mathematical contents, it is important to be proficient in both mathematical and chemistry concepts as well as interconnections…

This study investigated the effects of the storytelling approach on improving of EFL learners' vocabulary knowledge. To this end, 30 upper-beginner EFL learners (out of a population of 134) were selected by means of an OPT test and were assigned to 2 groups: 1 experimental and 1 group. The participants were selected from among young EFL learners…

To understand learners' appropriation of technological tools and geometrical understanding, we draw on the theory of instrumental genesis (Lonchamp, 2012; Rabardel & Beguin, 2005), which seeks to explain how learners accomplish tasks interacting with tools. To appropriate a tool, learners develop their own knowledge of how to use it, which…

The world all around us is rapidly developing. We are witnessing the rapid evolution of technology and communication. This means new challenges and responsibilities to future strategies and attitudes. Today's operating systems and development environments apply the principle of OOP; therefore today's developments are inconceivable without the…

The purpose of this study was to investigate the effects of using dynamic geometry software on preservice mathematics teachers' spatial visualization skills and to determine whether spatial visualization skills can be a predictor of success in learning analytic geometry of space. The study used a quasi-experimental design with a control group.…

The pilot research presented here explores the classroom use of Emerging Literacy in Mathematics (ELM) software, a research-based bilingual interactive multimedia instructional tool, and its potential to develop emerging numeracy skills. At the time of the study, a central theme of early mathematics curricula, "Number Concept," was fully…

The purpose of this study was to compare the influence of management styles of head teacher's on pupils' performance in private and public primary schools in Nakuru municipality at Kenya Certificate of Primary Education level. The population comprised of teachers and head teachers in public primary schools. The study adopted the ex post facto…

Teachers' job satisfaction leads to job continuity, which in turn affects teacher performance as well as the effectiveness of their institutions. The purpose of this study was to identify if there was a relationship between the Organizational Citizenship Behavior (OCB) and Job Satisfaction (JS) of teachers since discretionary behaviours have a…
