GPS sensor-based mobile learning for English: an exploratory study on self-efficacy, self-regulation and student achievement
© The Author(s) 2015
Published: 17 November 2015
This study investigated the effects of self-efficacy and self-regulation on student achievement in a context-aware learning environment. Particularly, an innovative global positioning system (GPS) sensor-based mobile learning system was used to facilitate English learning of different plants on campus. A total of 41 university students participated in the study, divided into high and low groups of self-efficacy and self-regulation. The findings showed that both self-regulation and self-efficacy were significant predictors of learning achievement in the mobile context-aware learning (MCL) context. Moreover, while the GPS-based MCL learning session had positive effects on learning achievement, no significant increase in self-regulation or self-efficacy was found in either the high or the low group, supposedly due to the short duration of the activity. The participants found the system easy to use and useful, but they also raised critical concerns that can inform future improvements. We hope this exploratory study can serve as a starting point from which more interactive, user-friendly GPS sensor-based learning systems will be generated and more areas of application will be further explored to foster self-regulated, self-motivated ubiquitous learning of mobile learners.
KeywordsContext-aware learning Ubiquitous learning Technology-enhanced language learning
Mobile learning has been highlighted by the 2010, 2011, and 2012 Horizon Reports (Johnson et al. 2012; Johnson et al. 2010; Johnson et al. 2011) as one of the most promising trends in higher education. Rapid advancements in cloud computing and the permeation of mobile devices in recent years have further pushed mobile learning into the era of mobile context-aware learning (MCL). A number of MCL-based systems have been developed for learners, with the ambition of realizing anytime, anywhere, and most of all, seamless/ubiquitous learning (Hwang and Wu 2014; Hwang et al. 2009; Hwang et al. 2011).
Self-efficacy and self-regulation are both crucial factors across different learning contexts (Sun and Rueda 2012). For self-regulation, research has shown that students’ learning achievement improved significantly after tutors facilitated self-regulation strategies (Montague 2007; Porath and Bateman 2006). Research has also shown that, with proper design, learners’ self-regulation could be enhanced with the assistance of technology, such as handheld devices and radio-frequency identification (RFID) (El-Bishouty et al. 2010; Puzziferro 2008; Sha et al. 2012).
While self-efficacy has been much studied in mobile learning and MCL research, learners’ self-regulation has not received equivalent research attention, as MCL studies that investigate self-regulation (e.g., El-Bishouty et al. (2010)) are relatively few in number. In addition, most of the existing MCL research has utilized RFID (Hsu et al. 2011; Tan et al. 2007) technology; however, the potential of the global positioning system (GPS) could be investigated further. Compared to RFID, GPS’s wide sensing range may help learners engage in learning activities without the problems of finding RFID tags. When Abowd et al. (1997) conducted their MCL study with GPS, they concluded that the wireless communication still needed improvement so that it can be seamlessly integrated with the MCL. With the recent development, GPS is now readily applicable to most smartphones without the need to purchase and allocate RFID devices. Based on the above rationale, the purposes of this study are threefold: firstly, to examine the effect of self-efficacy and self-regulation on learning achievement in a GPS-based MCL; secondly, to explore the overall effectiveness of the GPS-based context aware mobile system on students’ learning achievement for English; and thirdly, we are interested in understanding participants’ user experience and attitudes toward the system for future improvement of the system.
Context-aware learning, by definition, refers to the situation in which learners enter real-life situations so that they can directly immerse themselves in the environment and sharpen their skills. Context-aware learning regards context as part of the learning content, and being in a real-life environment will facilitate the learning process (Schank and Kass 1996). The aim is to encourage learners to investigate knowledge and learn to use it in a realistic and appropriate environment (Brown et al. 1989; Herrington and Oliver 1995). Even though context-aware learning has created potential for authentic learning and performance, Brown et al. (1989) remind us that a guide is indispensable to helping learners understand the purpose and procedure, as well as the requisite strategies to resolve ill-defined problems. Through such guidance and support, learners are more able to exploit and reflect on their learning progress, as well as understanding how they can apply what they have learned to different real-life situations through the learning by doing approach.
In the past, context-aware learning was frequently linked to teaching outside of the classroom, such as holding exhibitions or visiting museums or ecological parks. With the advancements in mobile technologies and the prevalence of mobile devices such as smartphones, tablets, and devices such as Google Glass, the traditional context-aware learning has evolved into mobile context-aware learning (MCL). Via MCL, learners are further allowed to send and receive information, and interact with others anywhere using their mobile devices. More specifically, learners’ locations and ambient information (e.g., temperature, altitude, etc.) can be detected so that relevant information can be provided to them for immediate consultation and seamless learning. As stated by Chang et al. (2011), mobile context-aware systems have the advantages of allowing learners to experience and observe real-life situations and so acquire knowledge to a fuller extent. Learners are more able to grasp the concept of abstract contents, in turn bringing about improved learning and performance.
Regarding research in this area, Zhao et al. (2008) developed the Mobile Learning Assistant for Mathematics that was adaptive to users’ preferences, learner characteristics, and the contextual environment. Particularly, adaptive contents were provided based on device capabilities and learners’ experience, and users were able to post questions (text message, photos, and video/audio captured by the mobile device) to participate in group discussion. The results showed that the users’ learning efficiency, as well as their motivation, increased as a result of using such an adaptive MCL approach. Hwang et al. (2009) applied MCL to the laboratory context. In the past, difficulties in operating laboratory instruments (e.g., performing single-crystal X-ray diffraction) had led to a high demand for experienced professionals to be on site so as to guide inexperienced operators. With the innovative context-aware expert system, appropriate steps and actions were displayed logically and systematically on mobile screens to novice operators. This approach was proved to reduce operational/experimental errors and decrease labor costs, as well as increasing the students’ overall learning efficacy.
In Abowd et al. (1997) research, GPS was integrated with their mobile context-aware tour guide (Cyberguide), including four components: map, information, positioning, and communications. They concluded that GPS is particularly useful and effective for outdoor learning activities. However, at that time, the wireless communication and the bandwidth were limited, which affected the efficiency of the GPS positioning. With the recent advancements in mobile devices, context-aware technology has become an important feature for mobile-assisted seamless learning or ubiquitous learning (Wong and Looi 2011).
Self-regulation refers to the awareness and set of behaviors adopted and practiced by a learner during the learning process of achieving a desired goal (Schunk et al. 2013). Self-regulation is not a mental ability or a skill for good academic performance; rather, it is a method involving the use of different strategies or goal setting so that learners can enhance their learning performance (Zimmerman 2002). Self-efficacy is individualized because learners have different abilities, traits, and personal goals. According to Schunk et al. (2013), when learners use self-regulatory strategies, they are able to learn more effectively and achieve set goals more easily. It is self-regulation that helps learners maintain self-awareness and guides their behaviors to reach their goals.
Previous attempts to facilitate learner self-regulation have been largely confined to traditional classrooms and student counseling. Zimmerman (2008), however, argued that approaches to self-regulated learning should be renewed to adapt to technology-enhanced learning environments in the twenty-first century. Research approaches should also be updated with new paradigms. In practice, specific strategies should be explored and validated for different contexts and pedagogical methodologies, such as learning systems that incorporate MCL. One example is the mobile context-aware and adaptive learning schedule (mCALS) tool developed by Yau and Joy (2008). This system allows learners to denote their location, identify whether their learning progress is on schedule, and proactively process unlearned content. Another context-aware learning system developed by El-Bishouty et al. (2010) helps undergraduates identify the different components within a personal computer so that they can assemble one on their own. This system provides learning content in accordance with the context and allows learners to adjust the contents, rendering flexibility, learner control, and personalized self-regulation strategies.
In summary, learning systems based on mobile learning and MCL can enhance learners’ abilities to self-regulate and use the appropriate strategies, thus assisting them in the learning process.
Self-efficacy originates from Bandura’s social cognitive theory (Bandura 1982), which states that external environments and the behaviors of others affect individuals’ mentality and behaviors. Through observation and social interaction, individuals formulate their self-judgment of their competence to perform a specific task. This self-judgment leads the individual to decide on the amount of effort to invest in completing a task or to abandon it even before attempting it (Bandura 1977, 1982).
The self-efficacy construct has been investigated in MCL research. Studies have found that self-efficacy affects individuals’ use of mobile devices to undertake MCL, as those with a relatively higher self-efficacy for mobile devices are more willing to make use of such devices to learn and vice versa (Kay and Knaack 2005; Tsai et al. 2010). A study by Kay and Knaack (2005) focused on trainee teachers who learned using laptops and wireless Internet access. They found that the long-term application of this learning method increased the trainee teachers’ self-efficacy in the use of laptops and their general computer ability, while it facilitated their future use of computers as teaching aids.
Self-efficacy was found to influence a variety of learning outcomes in MCL contexts. In Tsai et al.’s study (Tsai et al. 2010), elementary students in the third to sixth grades used MCL with plants in their school using a personal digital assistant (PDA) and undertook book-based research before completing a questionnaire on self-efficacy. Learners with higher self-efficacy and confidence in using the PDA were better at learning with it. Furthermore, when a person’s self-efficacy for mobile devices increased, their anxiety for using such devices reduced (Kwon et al. 2007; Tsai et al. 2010). Hwang et al. (2011) developed a PDA-based context-aware learning system for elementary school students to observe butterflies in a real garden. In addition to significant improvements in learning achievements, there was also an increase in self-efficacy for using computers to learn.
Chularut and DeBacker (2004) consider that an effective learning strategy or method (for example, the use of concept maps) helps students to learn English and improve their self-efficacy for English. Wong (2005) also found that students who used such strategies performed better, thus leading to improvements in their self-efficacy for English. Their self-efficacy levels in turn affected their future learning performance and strategy use. Bouffard-Bouchard et al. (1991) found that self-efficacy is an important factor influencing self-regulation during the English verbal learning tasks. It follows that self-efficacy and self-regulation (e.g., goal setting, task strategies, help seeking, etc.) may be intercorrelated constructs. It would be of value to include both constructs in MCL studies to explore their joint effects on learning outcomes.

The GPS-based MCL system
The instruments used in this study include questionnaires on self-regulation, self-efficacy for English and mobile devices, perceived ease of use and usefulness of the system, and an achievement test on the plants. The Motivated Strategies for Learning Questionnaire (MSLQ) developed by Pintrich et al. (1991) was used to measure self-regulation, self-efficacy for English, and learning strategies. We translated the questionnaire according to the conditions of the study without revising the intended meaning of the questions. Prior to the formal study, experts helped examine the contents of the questionnaires translated into Chinese to ensure that the translated questions conveyed the intended meaning. The original MSLQ uses a seven-point scale. For consistency, we used a six-point Likert scale throughout this study, with 6 and 1 each denoting “strongly agree” and “strongly disagree.” The Cronbach’s alphas of self-regulation, self-efficacy for English, and learning strategies were .69, .88, and .83, respectively. The instruments used in this study were adapted from existing validated scales. We also measured participants’ self-efficacy for mobile devices. Items from Tsai’s (Tsai et al. 2010) PDA self-efficacy survey (PSS) were adapted and slightly modified to fit the purpose of this study. A sample question is “In the u-learning context, I think I can read the content on the screen using a smartphone.” The Cronbach’s alpha was .91. The confirmatory factor analysis (CFA) of model fit indicated χ2 = 6.50, p = .89, RMSEA = .00, CFI = 1, and SRMR = .03. Based on the model fit criterion proposed by Hu and Bentler (1999) (CFI > .95, RMSEA < .08, and SRMR < .08), a good fitting result and construct validity were obtained. The values of factor loadings were between .97 and .61, reaching the significant level of .05.
Participants’ perceived ease of use and perceived usefulness of the GPS-based MCL system were based on the Technology Acceptance Model (TAM) questionnaire proposed by Davis (1989). Items were slightly modified to fit the purpose of this study. Sample questions include “It would be easy for me to become skillful at using the GPS-based MCL System” (perceived ease of use) and “I would find the GPS-based MCL System useful in learning about different plants in English” (perceived usefulness). The Cronbach’s alphas were .89 and .86, respectively.
Lastly, participants’ learning achievement was measured by the self-developed plants in English test. The test contained ten items. A sample question is “In which month does the Blackboard Tree (Alstonia scholaris) bloom?” The difficulty level of the test on average was .74. The discrimination power of D value was .40 on average, indicating the quality of items was considered good (Ebel and Frisbie 1986).
The GPS-based context-aware mobile learning activity took about an hour. The participants went around the campus with their smartphones (see Figs. 3 and 7), matched their locations using the MCL system, and read the learning content and related guidance (see Fig. 4 as an example). After completing the session, they took the plants in English achievement test and completed post-test questionnaires on self-regulation, self-efficacy for English and mobile devices, and the perceived ease of use and usefulness of the GPS-based MCL system. Lastly, we individually interviewed all of the participants to obtain their feedback on the learning content and operation of the learning system.

The above findings are in line with El-Bishouty et al. (2010) study wherein learners with better self-regulation performed better using the context-aware learning system. Our findings also echo Sha et al. (2012) study wherein more self-regulated students received higher achievement scores in their MCL learning context. As mentioned earlier, MCL studies that investigate learners’ self-regulation are relatively few in number. Our study adds evidence to the critical role of self-regulation in MCL learning. In the outdoor learning activity without instructor, self-regulation influenced learning performance. It is possible that the learners with high self-regulation employed the effective learning strategies and behaviors (e.g., posting questions on the discussion board, planning the route) during the limited learning time. More studies are suggested to examine detailed self-regulation strategies, such as goal setting, environment structuring, time management, help seeking, etc., to explore how these strategies could be facilitated to improve student achievement in the context of an MCL environment. At this point, we suggest that teachers or facilitators be attentive to learners’ self-regulation and provide differentiated learning tasks appropriate for them.

RQ3: To what extent do self-regulation, self-efficacy, and learning achievement change over the duration of the GPS-based MCL learning activity?

Low (n = 16)

However, it was surprising to find that participants’ self-efficacy for mobile devices decreased from the pre-test to the post-test, although once again, the change was not statistically significant (see Table 8). It is possible that the participants had over-estimated their abilities prior to using the devices for learning. After using the GPS-based MCL system, they realized that their self-efficacy was not as high as they had previously thought. On the other hand, the result might also reflect some usability issues. The GPS MCL system might not be very user-friendly so that participants’ confidence decreased after using the system.
RQ4: What are users’ perceptions of and attitudes toward the GPS-based MCL system?
Perceived ease of use
‘Some parts of the content were excessive. The contents of the different sections could have been distributed more evenly. Try not to display too much information.’ (Participant 4)
‘Looking back on the entire experiment, I felt as though I was only looking at my mobile phone throughout the process, without any on-site interactions.’ (Participant 3)
Participants also commented on the forum embedded in our MCL system, with some saying that when they used it to post messages or questions on site during the learning session, they expected to receive instant responses from peers. However, they did not receive timely feedback to resolve their doubts, making them feel that the forum was ineffective. As such, in the future, we will revise our design of the learning tasks to facilitate on-site interactions, such as posting guiding questions on the forum beforehand. A few participants further suggested incorporating a search and query function so that they need not switch to another page. This comment provides valuable information for us to improve the user interface of our MCL system.
Unexpectedly, we realized that some learners were not very familiar with the campus environment. Although we gave the learners a simple hand-sketched map during the orientation, they still encountered difficulties finding the learning locations. They expressed that the map would have been more helpful if it indicated more buildings, locations, or landmarks. Two participants who had recently enrolled in the university even suggested providing an actual learning route.
Besides participants’ feedback, we also noted some problems or issues ourselves. Regarding the technical aspects of the GPS-based MCL system, it is ideal to set a wider range to avoid non-detection. Yet, the drawback is that it will take longer for the system to position and respond, especially when we are using different types of mobile devices or when many users are using the system. In the near future, we plan to figure out an exact balance point between detection and speed, meanwhile updating our server to increase the database processing capabilities for more users.
Limitations and conclusion
This study has its limitations; foremost is that the duration of the learning session was only 1 h due to practical considerations. In the future, we will increase the time span so that the learners have sufficient time to go around the campus with their smartphones, match their locations using the MCL system, and apply more diversified learning strategies. Furthermore, this study is exploratory in nature, and we have not included a control group at this point. Future studies may employ an experimental design to closely examine the causal effects of the GPS-based MCL systems on learners’ self-regulation, self-efficacy, and learning achievement.
Despite the above limitations, this study utilizes a self-developed GPS mobile context-aware learning system to investigate the effects of self-regulation and self-efficacy on English learning. So, as to improve the system, we explored participants’ user experiences, including their perceived ease of use, perceived usefulness, and how it could be improved. Findings from this study may provide reference for the design and utilization of GPS sensor-based context-aware mobile devices in teaching English and related subjects. We hope this study can serve as a starting point from which more interactive, user-friendly GPS sensor-based learning systems will be generated and more areas of application will be further explored to foster self-regulated, self-motivated ubiquitous learning of mobile learners.
