Investigations of face identification have typically focussed on matching faces to photographic IDs. Few researchers have considered the task of searching for a face in a crowd. In Experiment 1, we created the Chokepoint Search Test to simulate real-time search for a target. Performance on this test was poor (39% accuracy) and showed moderate…

In this digital ITEMS module, Dr. Brian Leventhal and Dr. Allison Ames provide an overview of "Monte Carlo simulation studies" (MCSS) in "item response theory" (IRT). MCSS are utilized for a variety of reasons, one of the most compelling being that they can be used when analytic solutions are impractical or nonexistent because…

Virtual laboratory simulations can contribute to the educational objectives related to practical classes, especially in situations of online or hybrid teaching. We present a proposal for laboratory activity involving the quantification of proteins with the biuret reaction and measurement by visible light spectrometry. The student will be able to…

A glass of water covered with a disk with a hole in it can be turned upside down without spilling the water in the glass, provided the hole is small enough and the disk is pressed against the rim of the glass. A quasistatic numerical simulation based on hydrostatic pressure and surface tension of water was used calculate the critical hole diameter…

Contribution: A didactic methodology, based on analytical expressions and experimental validation, to describe the process of abrupt current interruption in a series RL circuit, that considers real passive components and uses a toggle switch as disconnecting device. Background: In undergraduate courses, circuits adopted in transient analysis…

Due to low cost monte-carlo (MC) simulations have been extensively conducted in the area of educational measurement. However, the results derived from MC studies may not always be generalizable to operational studies. The purpose of this study was to provide a methodological discussion on the other different types of simulation methods, and run…

With the anticipated increase in narrative video games entering the English classroom, the particular features of the genre need added attention. One of these features is the stronger perceived relationship between a player and the character than a reader and a character. While this has benefits for effective storytelling, it also creates the…

At the end of the 18th-century, Charles Coulomb developed an apparatus to study the force between two electrified beads which allowed him to obtain his famous Coulomb's law. Today, as one of the most fundamental outcomes in classical electromagnetism, his result is revisited in most high school physics courses, where students are asked to…

Digital educational technologies offer the potential to customize students' experiences and learn what works for which students, enhancing the technology as more students interact with it. We consider whether and when attempting to discover how to personalize has a cost, such as if the adaptation to personal information can delay the adoption of…

Learning practices in education are constantly evolving to provide high-quality education. One of the trends used to provide high-quality education is incorporating technological tools to teach and learn STEM concepts. Implementing physical manipulative tools and virtual manipulative tools in STEM classrooms positively influenced conceptual…

In today's society, student safety is the number one concern of school administrators. As such, the need to continuously think, practice, and grow as an educational leader charged with keeping students safe is of paramount importance. This action research aimed to increase school administrator self-efficacy in a community of practitioners during…

Two overlapping trends in the U.S. educational environment have given rise to this study: the changes in the demands placed on school principals over the past decade (Hess & Kelly, 2005; Davis, Darling-Hammond, LaPointe, & Meyerson, 2005; National Association of Secondary School Principals & National Association of Elementary School…

Little research exists on the use of video games as instructional tools in music education. The purpose of this pilot study was to examine the effects of two different video games on rhythm performance and to determine whether the level of flow achieved during the games had an impact on the results. Collegiate music students (N = 8) participated…

Purpose: In light of growing attention to promoting democratic learning opportunities in the EU and the US, this study provides insight into student opportunities to engage in the organisation of mock elections in Dutch high schools, and constraints that teachers identify in implementing mock elections. Approach: A survey study was conducted. One…

Using classical test theory and item response theory, this study applied sequential procedures to a real operational item pool in a variable-length computerized adaptive testing (CAT) to detect items whose security may be compromised. Moreover, this study proposed a hybrid threshold approach to improve the detection power of the sequential…
