ULearnEnglish: An open Ubiquitous System for Assisting in the English Vocabulary Learning

Abstract

Language learners often face communication problems when they need to express themselves and do not have this ability. On the other hand, continuous advances in technology create new opportunities to improve second language (L2) acquisition through context-aware ubiquitous learning (CAUL) technology. Since vocabulary is the foundation of all language acquisition, this article presents the ULearnEnglish, an open-source system to allow ubiquitous English learning focused on incidental vocabulary acquisition. To evaluate the proposal, 15 learners used the system developed, and 10 answered a survey based on the Technology Acceptance Model (TAM). Results indicate a favorable response to the use of the learner context to assist them in their learning. The ULearnEnglish achieved an acceptance of 78.66% for the perception of the utility, 96% for the perception of ease of use, 86% for user context assessment, and 88% for ubiquity. This study presented a positive response in using the location of users to assist their learning. Among the main contributions, this study demonstrates an opportunity for ubiquity use in future research in language learning. Also, furthers studies can use the source available to evolve the model and system.

The Development of U-Learning Innovation to Promote Research Potential: Analysis by Advanced Statistics, Srinakharinwirot University, Thailand

“…The third category includes course learning systems, such as an open ubiquitous system to assist in learning English [14], a blended mobile learning model for learning through tablets from local science learning stations [15], and the effect of a ubiquitous learning management system using imagineering to enhance learning achievement and multimedia creation skill for those enrolled in a digital multimedia course [16].…”

Potential Use of Propolis as Endodontic Irrigant

“…Irrigating solutions are used in endodontic treatment in order to eliminate bacteria from root canals. Several studies have been carried out in the search for irrigants that combine better properties, including antimicrobial activity, low or no toxicity to periapical tissues, solubility and ability to dissolve organic matter [3,4]. Intracanal medications are used as adjuvants in endodontic treatment, with the aim of moderating pain, reducing remaining bacteria and their metabolites, and accelerating the healing process [5].…”
