Present Subject

The use of existing and emerging technologies in teaching and learning provides the opportunity to present subject-area content using devices, programs, and venues in ways that promote higher-order thinking and long-term retention. In the last decade, advances in artificial intelligence (AI) have resulted in the development of virtual reality programs that enable end-users to interact with content in third and fourth-dimensional interactive spaces (i.e., extended reality or XR). The transformation beyond traditional face-to-face or two-dimensional teaching and learning has resulted in an unforeseen digital side effect. The digital side effect presents in the form of deepfakes or the deliberate alteration of audio and visual content to advance a specific point of view. The premise of this chapter is to present a primer using the technological, pedagogical, and content knowledge (TPACK) and levels of use construct to mitigate the presence of deepfake and malinformation in subject-area content when working in XR environments.

Based Instruction

This chapter presents a case study of online teaching in Statistics and Operations Research (OR) at the Open University of Catalonia (UOC). UOC is a purely online university with headquarters in Barcelona, Spain, with students from many countries. As common to most math-related knowledge areas, teaching and learning Statistics and OR present difficult challenges in traditional higher education. These issues are exacerbated in online environments where face-to-face interactions between students and instructors as well as among students themselves are limited or non-existent. Despite these difficulties, as evidenced in the global growth of online course offerings, Web-based instruction offers comparative benefits to traditional face-to-face instruction. While there exists a plethora of literature covering experiences and best practices in traditional face-to-face instruction in mathematics, there is a lack of research describing long-term successful experiences in Statistics and OR online courses. Based on the authors’ experiences during the last decade, this chapter aims to share some insights on how to design and develop successful online courses in these knowledge areas.

Higher Education Teaching

The Corona Pandemic has a major impact on teaching at universities. Various stakeholders have to face new challenges when face-to-face courses are no longer feasible. The management of higher education institutions, teachers and their teams as well as the IT and didactics support are called upon to develop digital teaching and learning formats at short notice. This article aims to identify specific tasks and responsibilities with the help of two literature analyses and to transfer the results into a holistic overview of agile change for Flipped Classroom courses. This overview is based on a Change Management (CM) process to which tasks of agile development and change are assigned. It thus combines both short-term development under time pressure from an agile perspective as well as long-term necessary steps of CM. The necessity and usefulness of such an overview was determined before its creation. For this purpose, a short quantitative survey was conducted with 65 people, who have already passed through the entire CM-process of digital change in higher education teaching and are therefore regarded as experts. The usefulness and necessity of the overview were confirmed. The concluding recommendations for action address the possible use of the overview, the implementation of individual tasks and the joint action of the stakeholders during and also after the Corona Pandemic, which should support the change to digital higher education teaching.

Previous work has established that a narrated animation is more effective at communicating a complex biological process (signal transduction) than the equivalent graphic with figure legend. To my knowledge, no study has been done in any subject area on the effectiveness of animations versus graphics in the long-term retention of information, a primary and critical issue in studies of teaching and learning. In this study, involving 393 student responses, three different animations and two graphics—one with and one lacking a legend—were used to determine the long-term retention of information. The results show that students retain more information 21 d after viewing an animation without narration compared with an equivalent graphic whether or not that graphic had a legend. Students' comments provide additional insight into the value of animations in the pedagogical process, and suggestions for future work are proposed.

Teaching Learning

It is no longer news that the novel Corona Virus pandemic (COVID-19) is ravaging and still destroying the world, killing so many people and sending economies in different countries into recession. COVID-19 came as a thief in the night in the household of traditional schooling. Gradually, the face-to-face traditional way of teaching and learning was immediately put on hold and all parties running to their shelves for cover as measure to avert the spread of the dreaded virus. What came up as a viable alternative to face-to-face or conventional mode of teaching-learning in school and higher institution is E-learning. So many of these educational institutions had to resort to learning through some E-learning platforms which include ZOOM, YouTube, Google Meet, Google Classroom, Duo, Free Conference Call, etc. This established the fact that majority of the organizations have made an instant switch to online collaboration inclusive of schooling systems. This paper therefore sort to examine how Nigerian schools are reshaping the schooling/education system as to align with the alternative model of teaching-learning most essentially as E-learning rest on major pillars which are undoubtedly deficient in Nigeria and amongst Nigerians. There are challenges to overcome in achieving the e-learning phenomenon in Nigeria, many students without reliable internet access, power supply and technology struggle to participate in digital activities, which hinder online learning. The paper was approached in an E-learning subscriber or user point of view around FCT Abuja metropolis which includes teachers and learners (students/pupils). Questionnaires were distributed to the E-learning users and also the teachers of E-learning. Data were collected and analyzed using percentage method and Likert method to arrive at a conclusion and useful recommendations were made to enhance e-learning during and post COVID-19 in the various educational institutions in Nigeria.

Education Process

Education landscape has changed dramatically due to Covid19 pandemic as in many country, conventional or face-to-face teaching and learning is no longer an option to avoid the spread of a virus.  E-learning become one of the best alternative to ensure education process could continue because experts believe world could only recover from this crisis in another two years. This paper will delve into students’ perspective about e-learning and their willingness to use e-learning. Technology Acceptance Model (TAM) was used to outlined this study. Majority of the student have an idea about what is e-learning. They also agree that e-learning able to accomplished learning and assessment proses as well as enable the interaction among students and student with instructor. Result also indicate, majority of the students have positive opinion towards e-learning nevertheless they prefer e-learning to be embedded in their education process (hybrid learning) as they are still prefer to have some level of face-to-face learning. However, this result cannot be used to generalize the opinion of all university’s’ student as diploma student tend to feel more comfortable to have face-to-face interaction with lecturer because they are in the transition period from school to university.

Impact Of Technology

Engaging in reflective practice is certainly not a new concept in the field of teacher education. Over the course of their pre-service training, teacher candidates characteristically experience changes in their teaching philosophy, and by extension, their pedagogic identities. Typically, these changes occur at the initial, midpoint, and final stages of the candidacy resulting from iterative reflective practices demonstrated through coursework and field experiences. Traditional models of teaching and learning situate these reflections through exchanges of experiences during discussions in face-to-face classroom or field-based settings. However, as existing and emerging technologies continue to impact teaching and learning in the 21st century, teacher preparation programs must respond in kind by adapting courses and aligning curricula to be responsive in the short term and nimble enough in the long term to change as institutions of higher education are only at the precipice of understanding the deeper impact of technology on teaching and learning.

La pandemia scoppiata nel 2020 ha determinato il trasferimento della didattica in presenza a una mediata da uno schermo. Il cambiamento ha posto l’attenzione su tale modalità sollevando domande sulla sua organizzazione. Il contributo esplora tali temi e si focalizza sugli spazi formativi digitali, analizzati dal punto di vista dell’usabilità: tale concetto racchiude l’efficacia, la piacevolezza, la facilità d’uso di un sistema (Nielsen, 1994). In questo studio, sono stati presi in considerazione due sistemi: Moodle e WordPress. Entrambi hanno come obiettivo finale la gestione di contenuti digitali, ma con finalità diverse. Nelle due piattaforme, opportunamente allestite, sono state implementate alcune risorse aperte di italiano come L2. Per la raccolta di dati sono stati impiegati un software di monitoraggio del comportamento degli utenti, interviste e questionari. L’analisi dei dati ha fatto emergere indicazioni sull’esperienza di apprendimento degli utenti e sul loro comportamento, nonché sull’efficacia degli ambienti e dei materiali Parole chiave: AMBIENTI DI APPRENDIMENTO DIGITALI, ITALIANO L2, USABILITÀ, ANALISI DELL’APPRENDIMENTO Since the explosion of the pandemic in 2020, teaching and learning practices have been forced to switch from a face-to-face model to one mediated by a screen. This change has placed intense attention on the character of computer-mediated instruction. This paper explores these themes and focuses on formative digital spaces, analyzed from the point of view of usability: this concept includes efficacy and the ease and pleasantness of use of a system (Nielsen, 1994). In this study, two systems were considered: Moodle and WordPress. They share the goal of managing digital content, albeit with different objectives. In both platforms, accessible, open-source L2 Italian materials were made available. For the data collection, interviews, questionnaires, and software monitoring users’ behavior were employed. The analysis of the data sheds light on the learning experience of the users and their behavior, as well as on the efficacy of the environments and materials.

Long Term Follow Up

There are few long-term follow-up studies of parasuicides incorporating face-to-face interviews. To date no study has evaluated the prevalence of psychiatric morbidity at long-term follow-up of parasuicides using diagnostic rating scales, nor has any study examined parental bonding issues in this population. We attempted a prospective follow-up of 85 parasuicide cases an average of 8½ years later. Psychiatric morbidity, social functioning, and recollections of the parenting style of their parents were assessed using the Clinical Interview Schedule, the Social Maladjustment Scale, and the Parental Bonding Instrument, respectively. Thirty-nine persons in total were interviewed, 19 of whom were well and 20 of whom had psychiatric morbidity. Five had died during the follow-up period, 3 by suicide. Migration, refusals, and untraceability were common. Parasuicide was associated with parental overprotection during childhood. Long-term outcome is poor, especially among those who engaged in repeated parasuicides.

Hydroxyurea Therapy

SummaryHydroxyurea (HU) is usually a well tolerated antineoplastic agent and is commonly used in the treatment of chronic myeloproliferative diseases. Dermatological side effects are frequently seen in patients receiving longterm HU therapy. Cutaneous ulcers have been reported occasionally.We report on four patients with cutaneous ulcers whilst on long-term hydroxyurea therapy for myeloproliferative diseases. In all patients we were able to reduce the dose, or stop HU altogether and their ulcers markedly improved. Our observations suggest that cutaneous ulcers should be considered as possible side effect of long-term HU therapy and healing of the ulcers can be achieved not only by cessation of the HU treatment, but also by reducing the dose of hydroxyurea for a limited time.
