The purpose of this research is to develop a scale to determine the perceptions of teachers working in secondary schools related to school safety. Alongside the social actors, the elements involved in achieving the goals of educational activities are important actors in the solution and implementation of the school security problems. Therefore,…

This study aims to evaluate the psychometric properties of the developed diagnostic assessment test and to identify student misconceptions in science in terms of school grades. 153 students were gathered by using random sample from 10th to 12th grade in senior high schools. The 32 items of the two-tier multiple-choice diagnostic test were…

Mobile learning (m-learning) has become an increasingly attractive solution for schools and universities that utilize new technologies in their teaching and learning setting. This study investigates the technical factors affecting the development of m-learning applications services from students' perspectives. It presents a model consisting of…

This paper explores the concept of dynamically generating definitions using a deep-learning model. We do this by creating a dataset that contains definition entries and contexts associated with each definition. We then fine-tune a GPT-2 based model on the dataset to allow the model to generate contextual definitions. We evaluate our model with…

Virtual Environment for Social Information Processing (VESIP™) is a web-based social information processing assessment developed for youth in grades 3-7. VESIP was developed to address: (1) the broader assessment of social information processing in a variety of socially challenging situations; and (2) the need for technically strong and scalable…

Digitally enhanced learning and teaching is widely used across the European Higher Education Area, with general acceptance growing over the years and institutions widely acknowledging the benefits it brings to the student experience. The strategic focus being placed on digitally enhanced learning and teaching has increased, undoubtedly accelerated…

While young people are generally better educated today than ever before, recent graduates tend to lack practical skills -- especially digital skills. Certification programs offer one effective way to address this digital skills gap. They give learners a way to gain the skills they need to compete, and also to demonstrate credibly that they possess…

The problem under investigation was the impact of restorative justice on lowering rates of exclusionary discipline among minority populations. The focus was primarily on students in grades K-12. More specifically, targeted groups included African American and Latino students (particularly males), and parents. Student/teacher relationships were…

This dissertation describes an experiment to investigate how learners with different levels of background in computer science learn core concepts of computer science, in particular, algorithms. We designed a study to focus on cognitive task analysis for eliciting the empirical mental elements of learning two graph algorithms. Cognitive workload…

Many classroom-observation instruments have been developed (e.g., Gleason et al., 2017; Nava et al., 2019; Sawada et al., 2002), but a very small number of studies published in refereed journals have rigorously examined the quality of the ratings and the instrument using measurement models. For example, Gleason et al. developed a mathematics…

This article uses definitions provided by Cronbach in his seminal paper for coefficient a to show the concepts of reliability, dimensionality, and internal consistency are distinct but interrelated. The article begins with a critique of the definition of reliability and then explores mathematical properties of Cronbach's a. Internal consistency…

I discuss the contribution by Davenport, Davison, Liou, & Love (2015) in which they relate reliability represented by coefficient a to formal definitions of internal consistency and unidimensionality, both proposed by Cronbach (1951). I argue that coefficient a is a lower bound to reliability and that concepts of internal consistency and…

Diagnostic classification models are psychometric models that aim to classify examinees according to their mastery or non-mastery of specified latent characteristics. These models are well-suited for providing diagnostic feedback on educational assessments because of their practical efficiency and increased reliability when compared with other…

This paper aims to develop and standardize the emotional maturity of high school teachers scale. Emotional maturity is a process in which the personality is continuously striving for greater sense of emotional health, both intra-physically and intra-personally. If teachers are emotionally mature which means if they have the ability to realize the…

Handling and analyzing to web financial data is becoming a challenge issue in knowledge management and education to accounting practitioners. eXtensible Business Reporting Language (XBRL), which is a type of web financial reporting, describes and recognizes financial items by tagging metadata. The goal is to make it possible for financial reports…
