Recent thrust of research has focused on non-conventional classrooms for teaching to EFL learners. Amongst the newly developed models, Unplugged Classroom Model (UCM) is the most debated one as textbooks are aside and the syllabus is based on conversation-driven activities. This study sought to determine the pros and cons of unplugged teaching for enhancing EFL learners' oral proficiency. From ...

In this paper, we present a group, asynchronous problem solving exercise designed to introduce non-computer science students to a variety of concepts from artificial intelligence and operations research. The exercise is designed to be a Computer Science (CS) Unplugged activity suitable for the online classroom. CS Unplugged is a methodology for teaching CS concepts using hands-on interactive ac...

BACKGROUND Most Brazilian schools do not have a continuous program for drug use prevention. To address this gap, the Ministry of Health adapted the European evidence-based program Unplugged to improve the drug use prevention efforts of Brazilian public schools. The aim of this study was to evaluate the process of program implementation in three Brazilian cities among middle school students betw...

Abstract. The principles and major steps of Enterprise Meta-Model (EMM) based development of Use Case model (UCM) in CASE system environment are presented in this paper. The Enterprise Meta-Model represents the key concepts of domain knowledge. The enterprise processes, management functions, and their interactions are considered as the critical components of the domain knowledge accumulated as ...

We introduced “Computer Science Unplugged” to our classes in junior and senior high schools. “Unplugged” is an education method of computer science without students using a computer at all. For our classes, we developed original teaching materials and methods for Unplugged. As a result, the students could learn the topics of computer science with interest by using Unplugged. They enjoyed the ga...

The phenomenon of unwanted commercial messages (UCM), including e-mail spam and emerging forms that target other Internet communications facilities, is analyzed from an information-economics perspective. The UCM industry is characterized as a tragedy of the commons. UCM traffic pays off for its senders when it is noticed and consumed by Internet users, and the industry is, therefore, dependent ...

We report practice lessons in 'Computer Science Unplugged’ (CS Unplugged) with assisted digital materials. CS Unplugged involves physical or group activities that lead students to computer science, and it is an excellent method of informatics education for beginners. However, such activities are not always easy for all students. Therefore, we designed various digital materials to assist student...

One of the earliest events in neuromuscular junction (NMJ) development is the accumulation of acetylcholine receptor (AChR) at the center of muscle cells. The unplugged/MuSK (muscle specific tyrosine kinase) gene is essential to initiate AChR clustering but also to restrict approaching growth cones to the muscle center, thereby coordinating pre- and postsynaptic development. To determine how un...

En route to their targets, motor axons encounter choice points at which they select their future path. Experimental studies predict that at each choice point specialized cells provide local guidance to pathfinding motor axons, however, the identity of these cells and their signals is unknown. Here, we identify the zebrafish unplugged gene as a key component for choice point navigation of pionee...
