Migrating the teaching and learning activities to the Internet invites a plethora of cyber risks and security threats. As distance learning has undergone a spectacular development and use recently, especially in the Covid-19 era-when it was, once, only temporarily established-, it is considered of utmost importance to ensure the issue of security a...

The abrupt outbreak of the coronavirus pandemic throughout the world in March 2020 resulted in the sudden closure of all schools, colleges and universities, institutions, and an unprecedented pivot to remote learning. Students and teachers were confronted with the the overwhelming challenge of migrating from the traditional face-to-face or hybrid m...

The SPI Manifesto provides a framework for guiding software development organisations in their improvement efforts. Based on the Values of People, Business and Change, which are supported and informed by one or more of the ten principles, the designer and developer can avoid pitfalls, minimise risks and make their business successful. It has been e...

Over a decade has passed since the inception of the SPI Manifesto. The fact that the signatories of the manifesto emanate from both the academic and the industrial communities enables a robust exchange of ideas and experiences. Continuous enrichment and refinement have been evidenced in publications, industrial projects, and consultancy across both...

Industry 4.0 is universally referred to as the fourth industrial revolution. It is a current trend of automation and data exchange in manufacturing technologies.

The Software Process Improvement (SPI) Manifesto is based on three basic values: people, business focus and organisational change underpinning the philosophy of SPI. In turn, these values bring up to date certain SPI principles serving as a foundation for action in software development. The authors of this paper carried out a pilot expert validatio...

Measuring viewers’ experiences of films has become a critical issue for filmmakers because all kinds of audiences now have access to new releases from all over the world. Some approaches have focused on the cognitive level of the experience, while others have emphasized the structure of films. Additionally, some have used quantitative objective met...

Software Process Improvement (SPI) has been founded on the belief that a well-defined and executed process is likely to produce a high-quality pro-duct. Improving a product might provide insights for future improvement efforts. However, this bottom-up approach does not necessarily lead to improvement, considering in particular that software product...

A password manager stores and handles users’ passwords from different services. This relieves the users from constantly remembering and recalling many different login credentials. However, because of the poor usability and limited user experience of password managers, users find it difficult to perform basic actions, such as a safe login. Unavoidab...

Lifelong learning is currently being embraced as a central process that could disrupt traditional educational paths. Apparently, the (ideal) type of learning often promoted is deep and meaningful learning, though it is not always required to be so. Deep learning goes beyond superficial knowledge assimilation of unlinked facts; it aims at developing...

A positive image would inspire the capable but underrepresented who might otherwise give up on computing.

Deeper learning and conceptual understanding are essential and critical elements for achieving learning process improvement in Computational Thinking (CT) curricula. For successful learning outcomes the school teachers of programming most probably have to familiarise themselves with two essential learning frameworks: i) tangible programming interfa...
