The coronavirus disease of 2019 (COVID‐19) pandemic has severely crippled our globalized society. Despite the chaos, much of our civilization continued to function, thanks to contemporary information and communication technologies. In education, this situation required instructors and students to abandon the traditional face‐to‐face lectures and move to a fully online learning environment. Such a transition is challenging, both for the teacher tasked with creating digital educational content, and the student who needs to study in a new and isolated working environment. As educators, we have experienced these challenges when migrating our university courses to an online environment. Through this paper, we look to assist educators with building and running an online course. Before we needed to transition online, we researched and followed the best practices to establish various digital educational elements in our online classroom. We present these elements, along with guidance regarding their development and use. Next, we designed an empirical study consisting of two surveys, focus group discussions, and observations to understand the factors that influenced students' engagement with our online classroom. We used the same study to evaluate students' perceptions regarding our digital educational elements. We report the findings and define a set of recommendations from these results to help educators motivate their students and develop engaging digital educational content. Although our research is motivated by the pandemic, our findings and contributions are useful to all educators looking to establish some form of online learning. This includes developers of massive open online courses and teachers promoting blended learning in their classrooms.

With ever-greater reliance of the developed world on information and communication technologies, constructing secure software has become a top priority. To produce secure software, security activities need to be integrated throughout the software development lifecycle. One such activity is security design analysis (SDA), which identifies security requirements as early as the software design phase. While considered an important step in software development, the general opinion of information security subject matter experts and researchers is that SDA is challenging to learn and teach. Experimental evidence provided in literature confirms this claim. To help solve this, we have developed a framework for teaching SDA by utilizing case study analysis and the hybrid flipped classroom approach. We evaluate our framework by performing a comparative analysis between a group of students who attended labs generated using our framework and a group that participated in traditional labs. Our results show that labs created using our framework achieve better learning outcomes for SDA, as opposed to the traditional labs. Secondary contributions of our article include teaching materials, such as lab descriptions and a case study of a hospital information system to be used for SDA. We outline instructions for using our framework in different contexts, including university courses and corporate training programs. By using our proposed teaching framework, with our or any other case study, we believe that both students and employees can learn the craft of SDA more effectively.
