The purpose of this proposed blended course design is to develop inter-professional communication and collaboration in critical thinking, inquiry, and learning. Implementation of inter-professional education between undergraduate students from different faculties enables a building of connections and relationships which could lead to improved collaboration in future inter-professional practice....
In order to image complex geological structures, seismic surveys acquire an increasingly large amount of data. While the resulting data sets enable higher-resolution images of the subsurface, they also contain redundant information and require large computational resources for processing. One approach for mitigating this trend is blended imaging, which combines the original shot records into a ...
The aim of this paper is to identify measurements of learning efficiency and learning effectiveness of blended learning and to analyze drivers of learning effectiveness and learning efficiency in learning environments of corporate education. Therefore a literature review of the AIS Electronic Library is done. With a single term search including “learning efficiency”, “learning effectiveness” an...
The Strategy and Practice of Blended Learning in Open and Distance Learning: Experiences from GDRTVU
In this paper we introduce our experiences of blended learning for open and distance learning in our university in recent years. We form our basic philosophies to implementing blended learning and make one blended learning system with 10 subsystems, which is consisted of online learning environment, instruction design, interaction, space, time, curriculum, learning material, community of practi...
sulphuric acid adsorbed on silica gel is a practical and useful catalyst for acetylation of varius alcohols, phenols and amines.
Aromatic amines are mammary carcinogens in rodents and exposure to aromatic amines may be associated with increased risk of breast cancer in women. Peroxidases present in milk can oxidize aromatic amines to reactive electrophiles which bind to DNA and induce mutations. Hydrogen peroxide, required for peroxidase-dependent oxidations, is supplied by milk xanthine oxidase and by the respiratory bu...
The first iron-catalyzed guanylation of amines is reported. Commercially available Fe(OAc)2 acts as an excellent catalyst for the addition of amines to carbodiimides. The reaction is broadly applicable to a variety of primary, secondary, and heterocyclic amines, and tolerates a wide range of functionalities allowing the easy preparation of a large family of guanidines. The low price and low tox...
This article describes a collaborative study of the blended learning approach, designed to pave the way for higher education students to integrate online and face-to-face learning environments in an ―Instructional Technology and Material Development‖ course at the University of Yildiz Technic in Turkey. The purpose of this study is to investigate the students‘ perceptions of the blended learnin...
We present an approach to the design of mixed reality spaces that aims to create a more harmonized and unified user experience. We refer to these as blended spaces. Blended spaces draw upon a description of physical and digital spaces in terms of the ontology, topology, volatility and agency. By describing physical and digital spaces in these terms we are able to use the process and design prin...
BACKGROUND Blended learning describes a combination of teaching methods, often utilizing digital technologies. Research suggests that learner outcomes can be improved through some blended learning formats. However, the cost-effectiveness of delivering blended learning is unclear. OBJECTIVE This study aimed to determine the cost-effectiveness of a face-to-face learning and blended learning app...
