A new experiment using mobile phones is proposed in which its audio frequency response is analyzed using the audio port for inputting external signal and getting a measurable output. This experiment shows how the limited audio bandwidth used in mobile telephony is the main cause of the poor speech quality in this service. A brief discussion is…

This article argues that the study conducted by Facebook in conjunction with Cornell University did not have sufficient ethical oversight, and neglected in particular to obtain necessary informed consent from the participants in the study. It establishes the importance of informed consent in Internet research ethics and suggests that in Facebook's…

Sensor systems are becoming pervasive in many domains, and are recently being generalized by the Internet of Things (IoT). This wide deployment, however, presents significant security issues. We develop security techniques for sensor systems and IoT, addressing all security management phases. Prior to deployment, the nodes need to be hardened. We…

Artificial intelligence (AI) has taken the world by storm, with new AI-powered tools such as ChatGPT opening up new opportunities in higher education for content creation, communication, and learning, while also raising new concerns about the misuses and overreach of technology. Our shared humanity has also become a key focal point within higher…

Student attitudes towards distance learning can affect both the acquisition of knowledge and the motivation to learn. This study explores student attitudes towards the following four topics: (1) technological and environmental impediments towards distance learning, (2) asynchronous versus synchronous course preferences, (3) online versus in-person…

Aim/Purpose: The objective of this study is threefold: (i) investigate how a group of subjects see the relationship between the integration of content, pedagogical and technological knowledge of their chemistry teaching in light of the teaching practices developed during the pandemic; (ii) present a framework for the integration of digital…

This study explores how students produce their own mini videos using the target language to share experiences and communicate with native speakers. Multimodality is used as a theoretical approach. Class observations and in-depth interviews were used for data collection, which was analysed by theme. The research results indicate that students deem…

The COVID-19 pandemic stimulated education system worldwide to employ online learning to support learning despite difficult times. To respond to this challenge and to promote Sustainable Development Goal (SDG) 4, advocating quality education, a virtual learning material (VLM) for Biology was articulated in Google Classroom. Accordingly, this study…

The transition to fully or partially online instruction for K-12 students necessitated by the 2020 COVID-19 pandemic highlighted the current lack of understanding of practices that support K-12 student learning in online settings in emergency situations but also, more troublingly, in K-12 online teaching and learning more generally. A systematic…

The study was conducted to evaluate the implementation of the Concurrent Classroom (CC) modality, a type of hybrid learning modality wherein an in-person teacher teaches in-person and online students simultaneously. The study utilized a quantitative research design to assess the implementation of the CC based on its viability, functionality, and…

Learning and innovation's skills are increasingly recognized as key factors separating students who are prepared for more complex environments of life and work in the twenty-first century, and those who are not. The relationship between the industry and the academia is undoubtedly in Mexico and several countries nowadays a very important social…

However, accessing information regarding threat assessment-related state mandates and recommendations can be a challenging and a time consuming task for school personnel as there is no single…

Research has noted the effectiveness of online tools (e.g., discussion boards) for supporting help seeking among class members. However, help seeking is not necessarily warranted via online learning tools because some factors (e.g., low Internet self-efficacy) may influence students' intention to use them. This study aims to identify the…

School psychologists are tasked with the job to implement evidence-based practices (EBPs) in the schools and are increasingly using the internet and social media applications, such as Pinterest, to find intervention resources.
