The purpose of this article is to present the results of a study conducted to investigate how the attributes of 3-D technology such as avatars, 3-D space, and comic style bubble dialogue boxes affect participants’ social, cognitive, and teaching presences in a blended problem-based learning environment. The community of inquiry model was adopted to analyse(More)
It is essential that nursing students develop the problem solving and critical thinking skills required in the current health care environment. Problem-based learning has been promoted as a way to help students acquire those skills; however, gaps exist in the knowledge base of the strategies used by learners.

In recent decades, the use of electronic systems, especially embedded systems such as mobile phones has been expanding rapidly. Such products use minimal amount of materials, generate less waste and noise, save space, and are considered cost-effective and attractive. In such devices, consideration needs to be given to both high power density and high chip(More)
Membranes with selective superwettability for oil/water separation have received significant attention during the past decades. Hierarchical structures and surface roughness are believed to improve the oil repellency and the stability of Cassie-Baxter state. Diatoms, unicellular photosynthetic algae, possess sophisticated skeletal shells (called frustules)(More)
On-the-job training and professional development is an integral part of today's workforce. In the current study, the authors investigated the use of a Performance Support System (PSS) designed to support educators to integrate technology during their lesson planning. The system is known as Matrix Aided Performance Support System (MAPS). The PSS is intended(More)
Technology provides the means to create useful learning and practice environments for learners. Well-designed cognitive tutor systems, for example, can provide appropriate learning environments that feature cognitive supports (ie, scaffolding) for students to increase their procedural knowledge. The purpose of this study was to conduct a series of usability(More)
