Background and Context: Gender research shows that women are better at reading comprehension. Other studies indicate a lower tendency in women to choose STEM professions. Since data modeling requires reading skills and also belongs in the areas of information systems and computer science (STEM professions), these findings provoked our curiosity. Ob...

The last two decades have seen the emergence of social-technological networks, which have changed the teaching methods and technological learning techniques. Social networks, learning technologies, and digital teaching tools are gradually becoming major work tools, integrated in the different educational systems. The integration of digital technolo...

This study involves e-learning skills via educational software, compared to instruction via educational software with the mediation of an instructor. In the last two decades, the role of the teacher-lecturer has changed, from teaching to guidance and instruction. The technological tools have changed the nature of the learning space and the manner i...

One of the immediate consequences of Covid-19 is that educational institutions all over the world had to make a rapid transition from frontal classroom learning to distance learning. The present study focuses on higher education and examines the implications of the transition from in-class learning to learning via the Zoom platform in an academic i...

Due to Covid-19, the higher education system in Israel faced rapid changes. Among these was the immediate shift to online exams. In this paper, we endeavor to scrutinize the different approaches to online-testing that diverge, converge, and complement each other on varying dimensions. The main questions we would like to address are how online exams...

This study addresses the effectiveness of learning via educational software. Recent decades have seen the integration of technologies, which are changing teaching and transforming teachers into mediating, facilitating, and guiding figures by means of digital learning methods that serve as a major tool in schools, colleges, and universities. The cur...

UNSTRUCTURED The desire for healthcare organizations to reduce the cost of chronic care and to prevent disease from occurring to begin with, has coincided with the development of new technology that is revolutionizing digital health. Numerous health-oriented mobile phone applications (referred to as mHealth apps) have been developed and are availab...

Background Noncommunicable diseases (NCDs) are the leading global health problem in this century and are the principal causes of death and health care spending worldwide. Mobile health (mHealth) apps can help manage and prevent NCDs if people are willing to use them as supportive tools. Still, many people are reluctant to adopt these technologies....

We address existing intergenerational gaps in use of technology and in digital language, and their potential negative consequences for the well-being of older-aged adults. We describe a new contextualization feature which we designed as an addition to existing instant- messaging systems, to overcome misunderstandings and communication breakdowns du...

Conceptual modeling of databases is a complex cognitive activity, particularly for novice database designers. The current research empirically tests a new pedagogy for this activity. It examines an instructional approach that stresses visualizing gradual transitions between levels of abstraction in different hierarchic levels of a relational databa...

Since database conceptual modeling is a complex cognitive activity, finding an appropriate pedagogy to deliver the topic to novice database designers is a challenge for Information Systems (IS) educators. The four-level TSSL model that is known in the area of human-computer interactions (HCI) is used to explain and demonstrate how instructional des...

Database conceptual modeling is an essential skill for Information Systems (IS) practitioners, but is a complex cognitive activity that is error prone. Finding an appropriate pedagogy to deliver the topic to novice database designers has been a challenge for IS educators. TSSL, a model that is known in the area of human-computer interactions (HCI)...

We apply a pedagogic approach named learning from errors (LFE) to the area of relational database modeling. Database modeling is a complex cognitive process characterized by a high level of element interactivity. Finding an appropriate pedagogy to teach database modeling is a challenge for information systems educators. One of the challenges that p...

This paper describes the design of a prototype for an emotionally enhanced computer mediated communication system which is aimed at compensating for the emotional distance between communicators. The prototype system encourages the sender to take the emotional perspective of the message receiver by giving the sender a sense of how his message may af...

This research focuses on improving relational databases design of novice designers. Teaching conceptual data modelling is a challenge to Information systems/Information Technology educators. Our goal is to test the effectiveness of the learning from errors approach in the area of conceptual data modelling of relational databases. For understanding...

Our goal is to test the effectiveness of the learning from errors approach in the area of conceptual data modelling of relational databases. For understanding the difficulties that n...

This study suggests a framework that analyzes individual preferences towards interactive systems by modeling users' evaluations of the cognitive costs and the benefits of using the systems. A graphical cost-benefit approach, which was originally applied in the area of system analysis and design to help decision-makers select computer systems for or...

Research problem: Adding contextual information to a core message has been shown to be critical in improving communication quality, especially in computer mediated communication. This paper models how people contextualize messages in the face of changing communication complexity. Research question: Can changes in communication complexity that occur...

The aim is to determine whether one of two hierarchical metaphors, the tree (parent-child) or the nested (object-container), is more suitable for designing educational interfaces for children. To cope with this is-sue an experimental educational application was designed with a prototype for each hierarchical metaphor. The application was evaluated...

This paper deals with communicational breakdowns and mis-understandings in computer mediated communication (CMC) and ways to recover from them or to prevent them. The paper describes a case study of CMC conducted in a company named Artigiani. We observed communi-cation and conducted content analysis of e-mail messages, focusing on mes-sage exchange...

Computer-mediated collaboration, a rapidly expanding form of work, introduces unique opportunities but problems as well. One of these problems is the higher risk of misunderstandings. Current communication theories suggest that misunderstanding may be reduced by contextualization, i.e., providing contextual information to explain a core message. Ho...

Computer-mediated collaboration, a dominant mode of organizational communication particularly in dispersed and multinational organizations, introduces unique opportunities but also new problems. One of these problems is the higher risk of misunderstandings, which is more likely to occur in computer-mediated teamwork than in face-to-face teams (Cram...

An experiment was conducted to test the relationships between users' perceptions of a computerized system's beauty and usability. The experiment used a computerized application as a surrogate for an Automated Teller Machine (ATM). Perceptions were elicited before and after the participants used the system. Pre-experimental measures indicate strong...

Metaphors are commonly used in our every day language. They structure our perceptions and understanding and are known to be very useful for educating new concepts. Metaphoric-based interfaces are considered in the HCI field as usable and easy to learn, because metaphors relate user actions in computerized systems to already familiar concepts. The g...
