This study aims to examine the effects of mixture item response theory (IRT) models on item parameter estimation and classification accuracy under different conditions. The manipulated variables of the simulation study are set as mixture IRT models (Rasch, 2PL, 3PL); sample size (600, 1000); the number of items (10, 30); the number of latent…

This paper presents an application of the Kalman filter in signal processing in instrumentation systems when the conditions of the environment generate a large amount of interference for the acquisition of signals from measurement systems. The unwanted interferences make important use of the instrumentation system resources and do not represent…

Systematic classroom observation is often used in evaluating and enhancing the quality of classroom instruction. However, classroom observation can potentially suffer from human bias. In addition, the traditional classroom observation is too expensive for resource-constrained environments (e.g., Sub-Saharan Africa, South and Central Asia). A…

Learning to program has long been known to be a difficult task, requiring a student to develop both fluency in the syntax and grammar of a formal programming language and learn the problem-solving approaches and techniques of computational thinking. The successful teaching strategies of the past have involved maintaining small teacher-student…

Reading on grade level by the close of third grade has been shown to impact a student's chance to graduate on time and therefore impacting future success. English learners (ELs), however, have struggled to read on grade level by the close of third grade as compared to their English-speaking peers. This quasi-experimental study determined if an…

The purpose of this research is to investigate the relationship between participating in an online software application focused on phonological processing and working memory and outcomes on foundational reading assessment measures. The online software application utilized was the Sound Reading Program. Students began the intervention working in…

The paper analyses the grades assigned by the professors of the University of Milan to their students at the end of written exams, comparing what happened in academic year 2018-19 and in academic year 2020-21, i.e., before and during the crisis caused by the COVID-19 pandemic. In March 2020, the lockdown closed the classrooms, stopping…

The reaction rate and rate law are chemical kinetics concepts that undergraduate students have difficulty understanding and applying in real life. A further challenge is the overall reaction rate of consecutive reactions. Herein we present a creative teaching practice using the analogy-based approach to exploit the similarities between the…

Numerous studies have been concerned with developing new authorship recognition systems to address the increasing rates of cybercrimes associated with the anonymous nature of social media platforms, which still offer the opportunity for the users not to reveal their true identities. Nevertheless, it is still challenging to identify the real…

Internet security safety awareness of parents is an important issue that should be addressed to raise the knowledge and awareness level about internet risks, information privacy, personal information, safety concerns and online attacks among parents to be able to teach their children to keep safe use on the internet. This study amid to investigate…

Eye tracking has become an increasingly popular research methodology among language researchers to examine online cognitive processing of second-language (L2) speakers and bilinguals. As the scope of eye-tracking research expands, there is a need to ensure that the methodology is used properly, so as to safeguard the validity of research findings…

This article illustrates the use of Microsoft OneNote as an Electronic Notebook for undergraduate biochemistry lab reports as well as student opinions of this use both before and during the online coursework shift during the pandemic.

With the increase in business transaction types, all sized companies widely use enterprise systems like SAP. Business schools work to integrate enterprise systems into the curriculum as a result of industry demands. However, studies show many business schools face challenges integrating enterprise systems into curriculum and maintaining integrated…

This paper discusses strategies that two high school geometry teachers employed to solve a challenging geometry problem with the aid of dynamic geometry software (The Geometer's Sketchpad (GSP). The teachers were part of a group of teachers who participated in a summer professional institute funded by the National Science Foundation. The paper…
