To Receive

Dr MathTM is a mobile, online tutoring system where learners can use MXitTM on their mobile phones to receive help with their mathematics homework from volunteer tutors. These conversations between learners and Dr Math are held in MXit lingo. MXit lingo is a heavily abbreviated, English-like language that is evolving between users of mobile phones that communicate using MXit. The Dr Math project has been running since January 2007 and uses volunteer tutors who are mostly university students who readily understand and use MXit lingo. However, due to the large number of simultaneous conversations that the tutors are often involved in and the diversity of topics discussed, it would often be beneficial to provide assistance regarding the mathematics topic to the tutors. This article explains how the μ model identifies the mathematics topic in the conversation. The model identifies appropriate mathematics topics in just over 75% of conversations in a corpus of conversations identified to be about mathematics topics in the school curriculum.

The worldwide use of cell phones has rapidly increased over the past decades. With the increasing use of mobile phones, concern has been raised about the possible carcinogenic effects as a result of exposure to radiofrequency electromagnetic fields. The objective of this study was to explore the perceptions and opinions towards brain cancer related to cell phone use among university students in Malaysia. The study revealed that the majority of the study participants believe that there is no relationship between brain cancer and hand phone use.DOI: http://dx.doi.org/10.3126/ajms.v4i1.7808 Asian Journal of Medical Sciences 4(2013) 1-4

Insight Into

As the world becomes increasingly interconnected, mobile phones has become the utmost preference device for most Malaysian to stay connected. Over the past decades, mobile phone users in this country has been increasing steadily. Percentage of individuals in Malaysia using mobile phones increased from 94.2% in 2013 to 97.5% in 2015 (DOS, 2016). According to the hand phone users survey carried out by MCMC (2017) , there were 42.3 million mobile phone subscriptions with a penetration rate of 131.2% to a population of 32.3 million at the end of 2017. In a study on university students of Malaysia, Ho et al. (2018) revealed that a substantial amount of them (18.83%) actually do not know what to do with the waste mobile phones. This reflects the low awareness amongst university students and the lack of formal management system in Malaysia. Moreover, the findings show the rate of replacements of even functioning phones is high and a significant high stockpile of the waste mobile phones, which in turn increase the generation of e-waste eventually. Tremendous amount of waste mobile phones are expected to be generated in Malaysia. Malaysia is now facing a challenge on how to deal with the ever growing generation of waste mobile phones from users. An insight into their e-waste management practices and key predictors in relation to waste mobile phones recycling intention are therefore essential. This would help to lay the foundation for developing a suitable, workable, effective and efficient system of collecting e-wastes. This study aims to probe into university students' behavioural intentions to recycle waste mobile phones. In the meanwhile, it is expected to derive the policy implications for the future expansion and enhancement of mobile phones recycling response rate.

Engaged learners are effective learners. Even though it is widely recognized that engagement plays a vital role in learning effectiveness, engagement remains to be an elusive psychological construct that is yet to find a consensus definition and reliable measurement. In this study, we attempted to discover the plausible operational definitions of engagement within an online learning context. We achieved this goal by first deriving a set of interpretable features on dynamics of eyes, head and mouth movement from facial landmarks extractions of video recording when students interacting with an online tutoring system. We then assessed their predicative value for engagement which was approximated by synchronized measurements from commercial EEG brainwave headset worn by students. Our preliminary results show that those features reduce root mean-squared error by 29% compared with default predictor and we found that the random forest model performs better than a linear regressor.

This chapter considers factors that can play roles in the use of mobile phones in university English as a Foreign Language (EFL) classrooms in Japan. While recent developments have made such devices an increasingly attractive alternative to computers in education, issues such as cost and privacy have been noted by other research to be of some concern. This study investigated the use and perceptions of mobile phones by 249 university students studying EFL in Japan. Results indicated that although students declared varying levels of proficiency with their mobile phones, most were able to complete the tasks queried. Among factors that might inhibit successful implementation of the use of mobile phones for education, cost and security concerns were minimal, but student reservations about using mobile phones for educational tasks appeared to be a mediating factor.

This chapter seeks opportunities to use mobile technology to improve human mobility. To this end, the chapter reports a diary study of university students’ use of mobile telephones for rendezvousing—arranging, and traveling to, informal meetings with friends and family. This diary study reveals, and suggests explanations for, a number of deficits in user performance: (1) rendezvousers occasionally become highly stressed and lose valuable opportunities; (2) outcomes are worse when rendezvousing at unfamiliar locations; (3) 31 to 45 year olds report more personal sacrifices than 18 to 30 year olds; and (4) when mobile phones are used on the move, the experience of communication is slightly worse than when phones are used prior to departure. Ways of using mobile technology to make good these deficits are suggested.

A 2 × 2 between-subjects design was used to examine the effects of message framing (gain vs loss) and color combination (red background with white characters vs white background with black characters) on 120 university students' perception of materials promoting the H1N1 flu vaccine and their willingness to receive the vaccine after they had read the materials. Each participant completed a 6-item questionnaire, and the results of an analysis of variance showed that participants rated vaccine information presented through loss-framed messages as having greater interest and leading to greater understanding. Loss-framed messages presented on a white background with black characters significantly increased the willingness of the participants to receive the vaccine.
