This study aimed to collect empirical studies related to technology enhanced language learning, and to systematically synthesize and review these studies to investigate the effectiveness of technology on language learning. The variables are year of publication, educational level, sample size, treatment duration, outcome measurement and types of devices. A total of 90 studies published between 1990...
Smartphones and desktop computers are ubiquitous in today's world. Due to the improved computing power and high portability of smartphone devices, users are performing more sophisticated tasks on their smartphones. This study compares the performance of a web-based task on a desktop computer with a mobile-based task on a smartphone. In addition, we have compared the overall user experience and preference...
A loading and testing system was developed by utilizing the technology of computer and hydraulic, which was employed to test the performance and quality of the maintained shearer haulage part. This paper was focused on the introducing on this system's theory of testing and loading, basic structure, and key devices. This system achieved the all experiments for the performance of the shearer haulage...
Since early eighties, not too many happened in analytical methods of performance valuation for actual computer and communication networks. The methods of the classic queuing theory (the mean value analysis, the convolution method) adopt unrealistic assumptions. The stochastic queuing network methods are not adequate for investigation of actual networks. Therefore, the paper presents an approximate...
In present study, we developed a pointing movement experimental device with visual feedback control function that is capable of perform the cognitive psychological procedure relate to own hand movements. It can serve to determining the human characteristics of pointing movement with or without visual feedback restriction. The main part of present device consists of a touch monitor, one set of light...
