Lasting Effects: What the Post Pandemic Return to In-person Teaching Tells Us About the State of e-Learning and its Future Trajectory

An outpouring of studies on the forced move to distance learning during the COVID-19 pandemic has revealed deep concerns with teaching and learning online. Yet, now that most learning is returning to pre-pandemic environments, it seems naive to assume that teachers and learners in these settings, are, or will ever be, the same. A deeper understanding of the impact of those online experiences on teachers and learners before, during and immediately after the pandemic can provide insight into how to move forward in our educational systems, where technology is increasingly implicated. The conceptual framework of the study was based on the three key features of contemporary e-learning theory: learner-centred, community-based, constructivist-driven. We mapped this framework against course design, teaching approach and the use of technology to conceptualize the conditions that existed in returning to in-person teaching in a blended learning setting. This framework uncovers the developments, constraints, openness, and fears of a group of Higher Education (HE) EFL Chilean teachers in leading students into technology-enhanced, 21st century learning environments. A qualitative case study methodology was employed. Findings are based on written responses to an 8-item open questionnaire (n=32) and individual, oral-based (n=13) interviews along with field notes. Evidence of a significant advancement in digital literacy skills on the part of teachers, and indeed students was uncovered. Untypical in the Chilean educational context, a strong shift towards valuing more social constructivist teaching practices and an awareness of the importance of fostering relationship-building in learning ecologies, both in person and online, was also revealed. Changes attributed to both positive experiences online and reactions to negative ones, bode well for those long seeking a shift away from a traditional educational mindset that existed prior to the pandemic. At the same time, the findings that reveal hesitancy and in some cases fear of the rapidly encroaching new technologies, especially Artificial Intelligence (AI) tools, indicate that for some teachers the embrace of technology has its limits. We discuss both encouraging and more concerning results in terms of the insight they offer and their implications for further e-learning research and for educational stakeholders operating in increasingly technology-dependent learning spaces.

Results show that, the expected values of periodic and seasonal means of the Buys-Ballot table are; (1) periodic mean mimic the shape of the trending curves of the original series and contains seasonal indices (2) seasonal mean is a function of the trending parameters of the original series and contain seasonal indices.
Integrated dual axis solar tracker using a single tracking motor

Solar energy is generally available in copious amounts globally and as a renewable energy resource, its importance now and in the future cannot be gainsaid. However, optimizing the rays of the sun by utilizing photovoltaic (PV) systems and aligning solar panels in a particular direction with regards to the sun’s rays always present their own challenges. Solar heating, molten salt power plants, and artificial photosynthesis are all examples of ever-evolving technologies that harness the sun's radiant light and heat for electrical energy. Solar trackers aim solar panels or modules directly at the sun. In this paper, a solar tracking system using Arduino is built. This system captures free solar energy, stores it in a battery, and then transforms it to the appropriate alternating current. It allows the energy to be used as a standalone power source in ordinary households. This system is built to adapt to its surroundings as quickly as possible. The system ensures that any software and hardware issues are minimized or wholly removed. Our system is put through its paces in terms of real-time responsiveness, reliability, stability, and security. Weather, temperature, and mild mechanical stresses are all factors that our system is built to withstand. The solar tracking system is the most effective technology to improve the efficiency of solar panels by tracking and following the sun's movement. With the help of this system, solar panels can improve the way of sunlight detection so that more electricity can be collected as solar panels can maintain a sunny position. Thus, this paper discusses the development of two-axis solar-tracking development using Arduino Uno as the principal controller of the system.
THE ROLE OF ONLINE LEARNING PLATFORMS IN EDUCATION

Digitization of education is a significant trend for reform and modernization in the global education environment. Digitization refers to the conversion of various information sources, such as texts, sounds, images, and videos, into digital language. Several analysts, including Tim Berners-Lee, the inventor of the World Wide Web, consider the emergence and growth of online education as a pivotal moment in the history of education. The European Union has adopted a digitalization approach to education. The EU 2020 education development plan focuses on digital technology, which was adopted in 2014. The primary goal of this document was to make effective progress in the field of information technology by integrating modern technologies and using technology alongside education. After conducting a comparative analysis of the existing conceptual apparatus, we have identified several fundamental concepts related to this problem area. Text, graphics, and multimedia information placed on Internet sites (servers) are commonly understood as Internet resources. This information is delivered to the user's computer in the form of a set of files or documents (including an archive) in various formats, such as HTML, DOC, PDF, and TXT. Internet resources also encompass executable programs placed on servers (distribution), which can be transferred to the user's computer for further use upon request. This article discusses how the concept of Internet portals is being used to address this problem, which is relevant across all areas of human activity influenced by the Internet. By creating a unified platform that aggregates and organizes educational resources, Internet portals can significantly enhance the accessibility and effectiveness of education. Keywords: Internet resources, effectiveness of education, digitization.
CREATING A HIGH-PERFORMANCE HADOOP CLUSTER CONSIST OF WEAK COMPUTERS WITHIN THE ORGANIZATION

Knowledge of practical methods of processing large amounts of data is akin to black magic. There are many tools and techniques for scalable data processing, in particular, caching (for example, using the mem cached program), replication, partitioning and, of course, Map Reduce/Hadoop. Hadoop is an open source framework that implements the Map Reduce distribution and reduction algorithm, which underlies Google's approach to organizing queries to distributed datasets that make up the Internet. This article is intended for programmers, architects and project managers involved in processing large amounts of data offline. It will describe how to get a copy of Hadoop, how to organize a cluster and how to write analysis programs. We will start by applying Hadoop in the default configuration to solving a few simple tasks, for example, analyzing changes in the frequency of occurrence of words in the corpus of documents; this will help to understand the basic ideas of Hadoop and MapReduce. Next, we will move on to the basic concepts of MapReduce applications developed using Hadoop, and along the way we will study the components of the framework, the application of Hadoop to a wide range of data analysis tasks and numerous examples of Hadoop in action. Keywords: big data, cluster, Hadoop.
