by Yuge Tu, Di Zou, Ruofei Zhang
Abstract: The integration of emerging mobile technology into the education domain has become increasingly ubiquitous. This research reviewed the advantages and challenges of mobile learning, discussed the key factors that promote effective vocabulary learning, and conducted a survey to investigate and identify the 10 most popular word learning apps. Based on the results, we analyzed the key features of the popular apps and summarized the elements that play crucial roles in leading to successful learning. Based on such analyses, we also developed a comprehensive framework for designing and evaluating vocabulary learning apps, covering dimensions, such as content quality, multimodal presentation, engagement, personalization, repetition, and usability. A popular app, Vocabulary.com, was also assessed utilizing the proposed framework. Users, evaluators, designers, and developers of word-learning apps are expected to benefit from this research by being provided with a comprehensive understanding of app-facilitated vocabulary learning and essential features of effective word learning apps.

Implementation of flipped classroom with personalised ubiquitous learning support system to promote the university student performance of information literacy
by Chuthathip Srisuwan, Patcharin Panjaburee
Abstract: In recent years, unfiltered information has become increasingly available to individuals. It is important to cultivate students information literacy, including evaluating, synthesizing, and using information appropriately and ethically. To reduce the limitations of course duration, this study applied the flipped-classroom pedagogy to create the in- and out-of-class learning environment in an information literacy course. Taking prior knowledge into account, a personalised ubiquitous learning support system was developed to support this pedagogy in this course. An experiment was conducted on an information literacy course at a university in Thailand to investigate the effectiveness of the proposed approach. The experimental results highlight that, in comparison with the flipped classroom with conventional ubiquitous learning support system, the proposed approach significantly improved students information literacy performance, self-efficacy, career motivation, and grade motivation.

The uSAP Model: A Ubiquitous Observation Protocol for Improving Teamwork Skills, Time Management and Accuracy in High Fidelity Simulation among Nursing Students
by Nantakarn Maneejak, Pratchayapong Yasri
Abstract: High Fidelity Simulation (HFS) is a computerised manikin that can mimic physiological responses of patients which has been used in preclinical practices among nursing students. To make learning with HFS meaningful, an effective observation model has to be developed so as to improve motor skill practices. This study therefore develops a ubiquitous observation model, called uSAP which concerns specific tasks of an observed role (S), full attention to a particular psychomotor practice (A) and nursing procedures involved (P), all of which can be done ubiquitously (U). The effectiveness of this observation model is assessed among 98 nursing students who are divided into three groups: those using the uSAP model, those doing observation without a certain guideline, and those without observation. Three different aspects of performance are compared composting of teamwork ability, speed in completing HFS tasks and accuracy in administering nursing tasks related to five vital signs. In addition, the study explores the usefulness of the uSAP model using semi-structured interviews with 10 nursing students who use it. Statistical analysis reveals that those using the uSAP model outperform their counterparts in all three aspects. The interview results illustrate that the uSAP model helps nursing students learn from peers mistakes, structure their ideas orderly, stay more focused and apprehend detailed actions effectively. It is therefore recommended for nursing instructors dealing with HFS to consider using the uSAP model for enhancing the quality of observation which can subsequently help improve nursing students performances.
Keywords: high fidelity simulation; nursing education; uSAP model; ubiquitous observation; vital signs.
Using Social Media in Mobile MOOC for Teacher Professional Development
by Esther Tan, Jun Xiao, Xuejiao Li, Mengying Cao, Marcus Specht
Abstract: This paper presents a ubiquitous and mobile MOOC platform to foster lifelong learning. Harnessing the technological affordances of WeChat (a mobile social media app), learners accessed micro-learning activities and received personal learning analysis report on their mobile phones. Premised on activity theory, the mobile MOOC design model spans across five dimensions of intelligent distribution: learning objective analysis, learner persona analysis, platform improvement based on learning analytics, m-learn tool selection and m-learn interactive environment where the latter forms the core of individual and collaborative learning. To investigate learning effectiveness, we analyzed the survey data of 117 Shanghai kindergarten, primary and secondary teachers in one mini-lecture. Findings showed that learning satisfaction and learning achievement is highly correlated with the learnability of the learning environment. The integration of a multidimensional activity and multi-scenario model showed great potential to successfully accommodate the complexity and diversity of mobile MOOC learning activities in a ubiquitous-learning environment.

by Abbas Ali Rezaee, Seyyed Mohammad Alavi, Parisa Razzaghifard
Abstract: This paper reports on a study investigating the potential effect ofthe impact of Mobile-based Dynamic Assessment (MbDA) on improving English as a Foreign Language (EFL) learners' oral fluency. To fulfil the purpose of the study, 120 pre-intermediate learners of English were randomly assigned to one of three groups (two experimental groups and one control group), each consisting of 40 participants. The participants in the experimental groups completed eight communicative tasks via dynamic assessment under two different contexts: MbDA via text-chat context and MbDA via voice-chat context. The speech rate, average length of pauses, the number of repetitions, and the number of reformulation served as dependent variables. The study found that the participants in the experimental groups who received MbDA improved their speaking ﬂuency signiﬁcantly compared with their peers in the control group.

Influential Factors of Working Adults Perceptions of Mobile-assisted Vocabulary Learning with Multimedia Annotations
by Ruofei Zhang, Di Zou
Abstract: With the development of technology-enhanced language learning, there have been increasingly more studies on mobile-assisted vocabulary learning with multimedia annotations. However, little research has been conducted to explore working adults use of multimedia annotations in authentic mobile learning environments, investigate their perceptions of diverse types of multimedia annotations, or discuss the factors that may influence their perceptions of multimedia annotations. To fill in these research gaps, the researchers of this project developed a multimedia-annotation-enhanced vocabulary learning app, iWORDS, and invited 24 working adults in Hong Kong to learn vocabulary using this app. After experiencing mobile-assisted vocabulary learning with four types of multimedia annotations (i.e., the textual, the pictorial, the text-plus-GIF, and the text-plus-video annotations), the participants were interviewed about their perceptions and preferences. The results indicated that working adults used textual annotations most frequently but showed strongest preference for text-plus-GIF annotations. Four factors, content quality, attractiveness, efficiency, and cognitive stimuli, played important roles in influencing working adults' preferences and perceptions of multimedia annotations. Based on the research results, we proposed some suggestions for the development, selection and usage of multimedia annotations in mobile-assisted vocabulary learning.

An Exploration of Inquiry-based Authentic Learning enabled by Mobile Technology for Primary Science
by Wing Kei Yeung, Daner Sun
Abstract: In science class, few opportunities were provided for the students to do inquiry in authentic contexts. The pedagogical integration of mobile technology into science authentic learning needs more explorations. Thus, we conducted a study on inquiry-based science authentic learning enabled by a mobile tool: nQuire-it. In inquiry-based learning environment supported by nQuire-it, students experienced various tasks by personally experiencing science inquiry in authentic learning contexts, which is suitable for learning abstract concepts and developing deep understanding of the science concepts. To examine the effectiveness of the mobile technology supported science authentic learning, in the study, students performance on science inquiry, conceptual understanding and the linkage of knowledge with daily life experiences were analysed and compared between groups. The results suggested the effectiveness of nQuire-it in students science learning and in promoting students motivation and interests in science learning and improving the linkage of knowledge in and out of classroom.
Keywords: nQuire-it; science inquiry; authentic learning; mobile technologies.
A mobile game-based learning system with personalized conceptual level and mastery learning approach to promoting students learning perceptions and achievements
by Narisra Komalawardhana, Patcharin Panjaburee, Niwat Srisawasdi
Abstract: Mobile game, which is one of digital learning tools, has been widely used for encouraging students learning whenever and wherever. However, several previous studies have indicated that without properly incorporating students personalized characteristic and learning assistance mechanism into the digital game-based learning environment might fail to motivate students learning and to help them acquire knowledge. To address this issue, this study proposes an integrated learning diagnosis and mastery learning mechanism to generate appropriate gaming stage according to the conceptual levels of an individual student in a pre-test and monitor learning during the gaming process. A mobile game-based learning system was developed based on this approach, and an experiment on the general science course was conducted in four Thai elementary schools with 282 students to evaluate its effectiveness. The experimental results showed that the students achieved the concepts of force and motion through the proposed approach. The findings of this study also highlight relationships between the proposed game and the conventional game in terms of students achievement clusters, performance, and perceptions.

Scaffolding spatial ability with augmented reality and virtual reality
by Jordan Wong, Kevin Yu, Nasser Giacaman
Abstract: Spatial ability is believed to aid comprehension of core STEM concepts. As there are no reliable methods for training spatial ability, this makes it a difficult skill to improve. This paper proposes Scaffolded Interactive Learning as a framework aiming to help students build on their spatial ability skills. It includes developing confidence, as well as scaffolding students to improve spatial ability. The framework is provided to scaffold students in solving questions that may otherwise perplex them. The framework was implemented in the form of two spatial ability trainer apps exploring the latest mobile technologies: augmented reality and virtual reality. A sample of 50 participants studying engineering were included in the evaluation, with the results showing that participants benefited in both skill and confidence from training in only a short period of time. The impact of the apps was analysed using in-app logging along with paper-based spatial tests. Participants with weak incoming spatial ability particularly benefited. These findings show the promising potential of augmented reality and virtual reality in improving spatial ability. Overall, targeted spatial ability tests showed statistically significant improvements while untargeted control tests showed insignificant differences.
Keywords: Spatial ability; augmented reality; virtual reality; STEM.

by Jintana Wongta, Chanakan Grosseau, Chitphon Yachulawetkunakorn, Chayanuch Watthana, Charoenchai Wongwatkit
Abstract: Abstract: In 21st century, innovation capabilities become essential for the engineering
students. To achieve that, creativity and operacy are strongly required and to be
promoted throughout the study program. During the school orientation, it is a
perfect time frame to not only make them familiar with the new learning
context but also provide them a series of programs that help promote their
creativity and operacy with new friends. Based on this perspective, this study
proposes a novel school orientation approach which integrates the benefits of
STEM and collaborative learning through a series of training and group
learning processes. Meanwhile, mobile devices and applications are used to
facilitate this collaboration. To investigate the effects of this approach on
creativity and operacy, the experiment has been conducted during the
orientation days with all newcomers. The results finally reveal that the
proposed orientation approach could promote students' creativity and operacy
in different aspects.

Trends and strategies for conducting effective STEM research and applications: a mobile and ubiquitous learning perspective
by Gwo-Jen Hwang, Kam-Cheong Li, Chiu-Lin Lai
Abstract: Science, Technology, Engineering, Mathematics (STEM) has been recognised by educators as an important educational objective in the 21st century. It provides a new vision of education by encouraging school teachers to engage students in problem-solving, critical-thinking and creative-thinking tasks using the knowledge and skills learned from multiple disciplines. While the effectiveness of STEM has been recognised by educators, the challenges of applying it to school settings have also been indicated, such as the difficulties in designing cross-disciplinary tasks and measuring students' learning performances. Mobile and ubiquitous technologies have been regarded as a potential facilitator which enables learners to learn across contexts with access to learning resources in anywhere and at any time. The use of these new technologies could provide new perspectives and opportunities for developing STEM activities and studies. This paper highlights the challenges as well as the strategies for implementing STEM activities in school settings and designing STEM research. It proposes several models for guiding researchers and schoolteachers to develop STEM learning design are proposed. In addition, it provides several strategies and measuring tools for developing in-depth experimental STEM studies.

Integrating research-based practices and mobile technology to support students with executive functioning challenges in post-secondary STEM
by Jingrong Xie, James D. Basham, Alyse Bensel
Abstract: The Universal Design for Learning (UDL) framework addresses the diverse learning needs of students with disabilities (SWDs) in post-secondary STEM education. The authors argue that supporting executive function skills (EFs) and learning strategies for students with disabilities (SWDs) during their learning process is important to the persistence and success of SWDs in post-secondary STEM education. Reviewed research indicates that EF challenges in post-secondary STEM education are a critical area for SWDs. Understanding current studies on the effectiveness of providing research-based practices (i.e., EF coaching and e-mentoring) for SWDs in post-secondary education can support the success of SWDs in post-secondary STEM education and diversify STEM workforce. We highlight how emerging mobile platforms, integrated with research-based instructional practices, can support SWDs' success and persistence in post-secondary STEM education. The implications and limitations are discussed.
Keywords: EF challenges; research-based practices; mobile technology; success and persistence of SWDs; post-secondary STEM education.
Surveying Chinese teachers' technological pedagogical STEM knowledge: a pilot validation of STEM-TPACK survey
by Ching Sing Chai, Morris Jong, Zhiming Yan
Abstract: As STEM education is increasingly drawing attention from different parts of the world, there is also an emerging call for STEM education to be synthesised with the TPACK framework for the purpose of teacher professional development. Unfortunately, teacher professional development for integrative STEM education anchored by engineering design has been lacking. This study attempts to integrate STEM and TPACK framework as a means to advance the state of affairs. In particular, a STEM TPACK survey was created and validated in this study. The exploratory factor analysis indicates that the four factors, i.e. the technological pedagogical science knowledge, technological pedagogical mathematics knowledge, technological pedagogical engineering knowledge and integrative STEM can be identified. The regression analysis indicates that the three TPACK factors can predict the teachers' integrative STEM efficacy. In addition, teachers who have experienced teaching STEM classes are generally more efficacious in their STEM TPACK knowledge. Overall, the study indicates that teachers' TPACK are associated with their efficacy in implementing STEM education. This implies that it is important to expound further teacher professional development efforts using the TPACK framework, and the inclusion of mobile apps could be important.

A personalised mobile learning system for promoting STEM discipline teachers' TPACK development
by Tanachai Kajonmanee, Pawat Chaipidech, Niwat Srisawasdi, Kornchawal Chaipah
Abstract: The contemporary education presents many challenges to improve teaching quality, including instructional practices knowledge, of teachers in science, technology, engineering, and mathematics (STEM) disciplines. To promote higher teaching competency for STEM teachers, the technological pedagogical content knowledge (TPACK) framework is recognisably and essentially adopted. To help improve TPACK for teachers, we proposed a mobile learning system that personalises digital learning contents by analysing learning styles, TPACK-oriented problems, content attributes, and mobile device and network capabilities. This study explored effects of the system on 78 in-service secondary-school science teachers in the Northeast of Thailand. The results indicated that the system significantly improved participants' TPACK skills in almost all aspects. Moreover, over 65% of participants were at least well satisfied with the system, and over 90% were at least moderately satisfied. These results showed that our system is a promising learning tool to improve STEM teachers' proficiencies under the TPACK framework.

by Kannika Daungcharone, Patcharin Panjaburee, Krittawaya Thongkoo
Abstract: Many studies have utilised the potential of mobile games to promote students' learning performance, while few have transformed compiler working steps into mobile games. In this paper, the researchers developed a mobile game by simulating the C compiler working steps with daily life situations. Afterward, the researchers applied a lecture-based learning approach to implementing the game in a Thai university C programming language course. The group implemented a mobile game-transformed lecture-based approach by comparing it to conventional lecture-based approach and mobile game approach. The findings of this study support the notion that students can better achieve the C programming language concept through a mobile game, especially when integrated with the process of lecture-based approach. The findings of this study also highlight the mobile game-transformed lecture-based approach support the students'motivation to learn the C programming language.

Consumer Perception towards Corporate Social Responsibility Practices: a study of the Malaysian Banking Sector
by Yeo Chu May, Amy, Steve Carter
Abstract: Organisations can gain enormous benefits when they are perceived as being socially responsible to their stakeholders. One of the important stakeholder groups that appear to be particularly susceptible to the banks Corporate Social Responsibility (CSR) initiatives is their consumers. Thus, this research aims to investigate how banks customers perceived CSR practices in the banking industry in Malaysia. Administering through a Google-form survey instrument, supplemented with a created link via Facebook and Whatsapp, a total of 240 responses were collected, resulting in a response rate of 80 per cent. Data collected were analysed using statistical tools such as descriptive statistics, correlations and multiple regressions mainly on the predictive power of the constructs in this study. The notable results indicated consumer awareness tended to be positively correlated to CSR practice and it was also one of the most important constructs contributing to the prediction of CSR with the exception of knowledge of consumers and purchasing decision. This suggests that bank managers need to take seriously consumer awareness into the next level of analysis, in which social media has an essential role to play in disseminating important information relating to CSR practices and implementation, including the use of mobile learning as an educative tool.
Keywords: CSR practices; consumer awareness; purchase decision; consumer knowledge; Malaysian banking industry.

THE INCLINATION TO PUBLIC DISCLOSURE OF FINANCIAL FORECASTS BY COMPANIES LISTED ON THE WARSAW STOCK EXCHANGE IN TIMES OF MOBILE LIFE
by Tomasz Sosnowski, Anna Wawryszuk–Misztal
Abstract: Voluntary disclosures play an important role in mitigating the information asymmetry on the financial markets and the mobile perspective can be a challenge for modern corporate reporting. Public disclosures are usually announced in a web and they can be accessed online by users. Using a sample of 267 non-financial companies listed on the Warsaw Stock Exchange between 2016 and 2018, we examine the link between some attributes of the companys tendency to future predictive reporting of earnings projections and its corporate governance system. Employing the logistic and multivariate regression analysis, we document that institutional investors are able to enhance the company to adopt better the practice of the voluntary disclosure of earnings forecasts, at the same time keeping under control the flow of more general forward-looking information to other stock investors. Moreover, the management and supervisory board size, as well as the presence of female members in the boardroom are also associated with the companys policy of future predictive reporting.

Enhancing Skill Prediction through Generalizing Bayesian Knowledge Tracing
by Tak-Lam Wong, Di Zou, Gary Cheng, Jeff Kai Tai Tang, Yi Cai, Fu Lee Wang
Abstract: Learning Analytics (LA) have been widely investigated and applied to understand and optimize the learning process and environment. Among a number of LA tools, Bayesian Knowledge Tracing (BKT) was developed aiming at predicting the probability that a skill has been successfully acquired by a learner. While current development has proved BKT to be sufficiently accurate in prediction and useful, the state-of-the-art BKT methods suffer from a number of shortcomings such as the incapability to predict multiple skills learnt by a student. In this paper, we extend the ordinary BKT model to predict unlimited number of skills learned by a learner based on a non-parametric Dirichlet Process (DP). Another characteristic of our approach is that it can easily incorporate prior knowledge to our model resulting a more accurate prediction. The extended model is more generic and able to handle border applications. We have developed two efficient approximate inference methods based on Gibbs sampling and variational methods.
Keywords: Bayesian Knowledge Tracing; BKT; learning analytics.
