Now that the basic technical standards for an open, global learning infrastructure are rapidly maturing, it is time to shift our focus to the development of an integrated toolset that hides the technical complexities from the end user and that enables the author, teacher and learner to be more effective and efficient. In this talk, we will discuss some new approaches to realise this idea and we...

This study investigates the profile of Chinese pre-service mathematics teachers’ Technological Pedagogical Content Knowledge (TPACK) through a sample of 106 people.

From the data collected from the scale, the findings reveal that Chinese pre-service mathematics teachers rated themselves as most competent in the factor of Content Knowle...

Proving the efficacy of certification standards?

Generative educational assessments such as essays or drawings allow students to express their ideas. They provide more insight into student knowledge than most multiplechoice items. Formative guidance on generative items can help students engage deeply with material by encouraging students to effectively revise their work. Generative items promote scientific inquiry by eliciting a variety of re...

Using novel data collected from a career intelligence website, we study whether and why high-tech firms rely more heavily on non-wage benefits, such as free meals, transportation subsidies, and athletic facilities (“work-related perks”). We find that employers engaged in IT innovation are more likely to offer work-related perks, but not more traditional non-wage benefits such as health insuranc...

In response to VO challenges, research and development efforts shall address different features and components of VO, that cover a wide spectrum of areas. Considering the complexity of building technical support infrastructures and applications for VOs, clearly at the time of such developments, the choice of best approach, standards, technology, commercial tools/systems, or R&D developed protot...

The aims of this paper are to use a birandom variable to denote the stock return selected by some recurring technical patterns and to study the effect of exit strategy on optimal portfolio selection with birandom returns. Firstly, we propose a newmethod to estimate the stock return and use birandom distribution to denote the final stock return which can reflect the features of technical pattern...
