Within digital ecologies, teachers routinely find an abundance of information related to their teaching. While many teachers pursue brute force searches for online ideas and resources, during the COVID-19 pandemic, teachers had to address pressing new challenges in online teaching in the most efficient ways possible. This chapter reports on an ongoing study of 16 teachers and how they relied upon digital social platforms to make the move to online teaching. Analysis revolves around socially-distanced video-recorded interviews with these teachers. Given their limited time, teachers had to be selective about what they deemed useful and relevant to their immediate needs. Strategic uses of digital social platforms served to address some of those needs. Specific strategies observed in the data regarding the development of pedagogy included joining teacher collectives, accessing expert-like spaces, and finding pedagogical inspiration within posts by teacher-influencers.

Address Space Layout Randomization

ROP (Return-Oriented Programming) is a kind of attack technique which makes use of the existing binary code of target systems. ASLR (Address Space Layout Randomization) is widely used to protect systems from buffer-overflow attacks by introducing artificial diversity to software. With ASLR software can be immune from ROP attacks to some extent. Due to the fact that ASLR cant randomize base addresses of executables code segments and its utility on 32-bit architectures is limited by the number of bits available for address randomization, attackers can successfully exploit a target system by using brute force in limited time. Thus, we proposed FLR, a function level randomization technique to mitigate ROP attacks. FLR randomly permutes functions in executables, making attackers assumptions on executables incorrect. We implemented a prototype of FLR and randomized ten executables. ROP attacks succeeded without FLR and failed with FLR.

Study Process

Human Anatomy tutors had to adapt to Covid-19 reality by restructuring their methods by teaching in spring – autumn in 2020 at the Department of Morphology. The aims of this study were to identify and understand the variety of solutions being utilized by tutors and to clarify new challenges and directions. The open-ended interviews were used to collect data from 15 Anatomy tutors. Thematic analysis, used to analyze the qualitative data, emphasized the tutors’ perceptions of remote practical anatomy classes’ efficiency. Tutors developed their action plans for online teaching and highlighted the preparation of new materials, adoption of new technologies and skills. Based on the results of the transition from face-to-face to online anatomy teaching, there were detected five thematic items that were related to tutors’ challenges. It was concluded that challenges that need to become a priority for tutors in online education concern mainly the special training courses, design of new models, video and/or online lectures, demonstration labs, practical classes, collegial contacts, technicians, IT-staff and colleagues support, consultation hours and communication. Future directions for tutors must be effective not only for increasing the quality of the Human Anatomy study process but also for the evolution of anatomy education.

Transferring the form of face-to-face learning in conventional classes to online learning is not only as simple as changing learning materials into all-digitalization as not all teachers try to make a proper and organized preparation before starting the online teaching process. With the limited time to practice speaking skills at the National Institute of Technology Malang, the teachers are expected to have the right planning and strategies for their classes. Therefore, this paper reports on the the use of ASSURE model in teaching speaking online from the perspective of two English teachers in the National Institute of Technology Malang. This qualitative study relied primarily on in-depth interviews of the two teachers to gather the information. This research’s findings and recommendations are expected to help provide insights in preparing and developing other online speaking classes to achieve better outcomes.

Learning to teach online presents new challenges to even seasoned instructors. In an age of technological wizardry, the author of this chapter proposes that there are no secrets to good online teaching. However, the effective application of sound pedagogy online requires time, effort, and planning. Using Collins and Berge’s framework for online teaching, this chapter outlines how novice instructors’ adaptation to the new medium must include attention to the pedagogical, managerial, technical, and social aspects of teaching. In so doing, online teachers are encouraged to move from a didactic, teacher-centered paradigm to a constructivist-based model where community and collaboration are valued equally with content.

Abstract Multi chip packages provide higher functionality in a module using multiplicity of dice. One specific packaging technology known as Stacked Chip-Scale Packaging raises new challenges for the failure analysis community. A methodology to perform full electrical isolation and failure analysis without damaging the electrical connectivity on either package or any of the dies in a stacked 2-die package is described. A second challenge is to obtain analysis result in a limited time frame in order to improve manufacturing yield and perform corrective action effectively. Example of successful failure analysis following this methodology on units with failure in packaging unit and units in failure in the die are presented.

This communication exposes the results of an ongoing study related to the use and potential of the Instagram social network as a complementary tool in the acquisition of competences for the students of the Sculpture II subject in face-to-face and online teaching. The objective of this research is to establish the theoretical foundations of a working model based on the use of ICT and social networks as possible propelling and inspiring elements of artistic practices, especially those oriented to the sculptural field. For this study, the group_f52 Instagram account has been created in order to enhance the learning of the contents of the subject, based on the communicative power that the image has on this platform, the possibilities of interaction and multiple contents that it offers, thus as its accessibility. The study, which is in the Interaction and redirection phase towards online teaching, was well received by the reference group. The audiovisual materials have been viewed by 80% of the members who follow the account and it is expected that, after the closure of the facilities, Instagram will become a virtual space for coexistence for the group.

The COVID-19 pandemic has set new challenges before the world in all areas including, education, and India is not an exception. The elementary, secondary and higher education system of our country is severely affected with this deadly disease. As such, the schools, colleges and universities have suspended their offline classes throughout the country since March last week of 2020. Amidst these challenges, it has also opened up new opportunities for the teachers, educators, and technocrats, etc. to use online virtual learning strategies for imparting learning experiences to students across the world. Thus, techno-pedagogy is the need of the hour in India and especially in Higher Education. However, the nation is gradually moving towards normalcy, and offline classes have been started by some of the states. Hence, it was necessary to assess how effective online teaching, learning and evaluation in the context of offline teaching, learning and examination. The present paper highlights the views of the undergraduate students on the feasibility of online teaching, learning and examination in the state of Arunachal Pradesh.
