With the trend of population aging, Taiwan, which has entered an aging society, is also gradually paying increasing attention to the learning and quality of life of the elderly (e.g., 1, 2, 3). Also, the use of technology among older adults in the current years has risen increasingly (4, 5). Accordingly, there have been numerous international research studies conducted on the digital use of the elderly (e.g., 6, 7–10). It is therefore clear that the issue of how digital technology can help to improve the lives of older people is a crucial and continuing high-demand issue.
Despite the increasing usage of technology among the elderly and the crucial role that digital learning has been found to play in enhancing the integration of older adults into their lives and learning (11, 12), there has been little research focusing on both acceptance and rejection of older adults’ digital learning. Previous research has indicated that participating in digital learning offers more significant positive benefits for the elderly (10, 13, 14). Nevertheless, before discussing the performance of older adults’ digital learning, the premise is that we should understand whether digital learning is interesting or terrifying, or whether older adult learners may have paradoxical hesitation toward digital learning.
Therefore, to shed light on the mechanisms behind a growing number of older adult learners who participate in digital learning, the current research aims to propose a theory entirely tailored made for older adult learners during digital learning. As a prerequisite, the current framework tries to integrate and unify all the elements and sequences that feature older adults’ specific situations regarding the process of digital learning involving precursors, the acceptance and barrier factors, intentions, perceived behavioral controls, and outcomes and behaviors.
1.1 Motivation and acceptance of digital learning for older adult learners
The Technology Acceptance Model (TAM; 15) is a theory that described how and why users come to accept and adopt technology. In TAM, perceived usefulness and Perceived ease of use have been showed to have a positive relation to intentions and actual behaviors. To extend TAM, several theories were created to further model this process regarding technology adoption, such as Unified Theory for Acceptance and Use of Technology (UTAUT 1&2) (16, 17). However, so far, few theories specifically tailored for targeting the elderly have been developed regarding technology or digital learning. When it comes to technology use or even digital learning, the elderly exhibit distinct motivation, learning patterns, and adaptation after being exposed to digital learning. Target specific characteristics and theories are a trend and urgent need with accumulating aging populations.
To discuss whether older adults participate in digital learning or not, we can start with reviewing older adults’ digital using circumstance. Hutto, Bell (18) indicated that self-efficacy is the mediator of older adults’ intention to use social media. Therefore, before discussing whether older adults willing to use digital techniques, we have to encourage older adults to participate in digital learning and it is important to address their concerns about "difficulty," "unfamiliarity," and "fear of falling behind." Instead, we should cultivate positive attitudes and mental states, such as "ease of use" and "sense of achievement" about using digital technologies. Moreover, the benefits of incorporating digital techniques into their daily life are also important factors in promoting the success of older adults. For example, Jung, Walden (19) investigated the reason of whether older adults use Facebook or not, and the result shows that the reason of older adults using Facebook includes “the ability to contact with people who usually cannot be contacted”, “the ability to share photos”, “the ability to be contacted by families and friends and social surveillance” and “the convenience to organize and communicate with social network”. In addition, by analyzing a series of qualitative interviews, Lüders and Gjevjon (20) found that the motivation of older adults to use digital techniques can be enhanced by several factors, such as the belief that "if my grandchildren can do it, so do I," followed by curiosity, awareness of the multiple functions of digital devices, and social interaction.
1.2 Barriers hindering the elderly from digital learning
Although many theories aim to extend TAM, few of them specifically discuss the barriers that hinder the use of technology or participation in digital learning. In fact, previous research has already indicated some obstructive factors or barriers regarding technology adoption or digital learning (e.g., 21, 22, 23). For example, Verkasalo, López-Nicolás (22) brought up a model and emphasized that some technical barriers can weaken the motivation of using technology. These technical barriers are based on different devices and specific, so they tried to distinguish the devices in this model and invited the user and non-users of these devices to participate in the experiment to confirm this model. Moreover, Hutto, Bell (18) and Jung, Walden (19) indicate that interface design and privacy protection are one of the obstructive factors of older adults using social media and digital technology.
In addition, through qualitative interviews, Lüders and Gjevjon (20) found that if older adults make an observation or social comparison through digital devices and feel socially excluded, then this would weaken their motivation to use digital devices. Seifert, Hofer (24) also pointed out that it is likely for older adults to feel socially excluded on the internet and this make them more unwilling to use the internet. Besides the issue of privacy protection and social comparison, the biggest problems are still the lack of digital competency and difficulty to use. For example, Jung, Walden (19) mentioned that the reasons for older adults’ unwillingness to use Facebook include the need for media richness, cue absent aspects of Facebook, unwillingness to spend time to get familiar with Facebook, and limited site skills. Research has also indicated that infrequent use of digital techniques among older adults hinders their ability to use them freely and leads to unfamiliarity with their operation, this in turn, can result in feelings of computer anxiety and technological fear (25). Although digital technology is crucial in improving the quality of life, a significant portion of adults and older adults lack basic digital competencies or skills. This knowledge gap creates a division between them and the younger generation, often referred to as digital natives, resulting in a phenomenon known as the generation gap. Oppenauer-Meerskraut, Kropf (26) investigated gaming design for older adults’ physical training also indicated that older adults might reject digital or gaming design.
To conclude, both acceptance and barrier factors are crucial for older adults regarding digital learning. The current research accordingly aims to explore older adults’ demands by weighting equally on both acceptance and barrier factors.
1.3 Approach-avoidance conflict in digital learning for the elderly: paradoxical hesitation towards technology
Approach-avoidance conflict refers to a conflict arises when people have two opposing psychological forces toward a certain object: approach and avoidance. Approach means pushing them toward a certain goal or having positive and desirable aspects toward the object. Avoidance refers to a force pulling them away from or having negative or undesirable force toward the object (27, 28).
As for approach force, the previous research on the usage of technology have primarily focused on the acceptance factors for general consumers, workers, and young people (e.g., 16, 17, 29). However, there are few discussions about the avoidance force or mental paradox of older adults while using digital technique. Young people or the workforce generally have a higher frequency and need for using technology compared to older adults, resulting in less mental paradox and shorter break-in periods. Previous research has also shown that older adults experience mental paradoxes when using technology (30, 31). For example, Wilson (32) investigated the relation between older adults’ emotional attachment towards a device and happiness showed that the increase of the frequency of using smartphone would strengthen the emotional attachment towards smartphone and raise their self-esteem. However, excessive emotional attachment to the device was found to reduce the sense of belongingness among older adults. Therefore, older adults should find the balance between “the increase of self-esteem by digital device using” and “the decrease of belongingness by deuced emotional attachment towards devices”.
1.4 Older adults digital learning outcomes and behaviors
Previous research on the outcome performance or learning behaviors of older adults’ digital technique using found out that the good or bad of the performance depends on how they use digital technique during the process and their attitude toward technology and. For example, Tirado-Morueta, Aguaded-Gómez (33) indicated that previous research on the acceptance of individuals toward technique just simply looked into whether they “accept it or not”. They thought that the performance of individual’s technique using should divided into three dimensions, the accessibility of physical distance, the frequency of use, and the purpose of using technology, which concluded three levels of access and use of technology: physical access, operational use, and informative-expressive use. In their research, physical access refers to the usage frequency; operational use means performing simpler task used for our daily life; informative-expressive use refers to more difficult tasks that require a higher level of skills.
Furthermore, the degree to which older people adapt to digital technology also depends on whether they are actively participating in society or only passively observing it. For example, previous research on older adults’ motivation and mental adaptation on using social media found that if older adults made directed communications with families or other social objects via Facebook, the decrease of loneliness and the increase of satisfaction of their social role were greater than those who made broadcast communications or just passively consumed the content (18). The discussion above can also apply on whether older adults initiatively participate in digital learning (for example, initiatively raise a question online or share knowledge) or passively participate in digital learning (for example, simply view websites for knowledge or listen to online courses).
Lastly, older adults’ attitude toward technique and the role technique plays in their lives also influence on whether they adapt to digital learning well or not. Hutto, Bell (18) indicated that older adults’ attitude toward digital technique should be as “augments” of daily life but not “replacements”. By doing so, older people can better adapt to the use of technology.
As discussed above, this research considers different levels of digital learning outcomes and behaviors by classified older adults as three types of learners based on (a) whether if digital learning is an autonomous choice; (b) whether if technology is regarded as augments to enhancing their life or as replacements of their original life; and (c) whether if high-level functions of technology were employed to assist daily needs.
1.5 Current study
The purpose of this study is to develop a new theory entirely customized especially for older adults while participating in digital learning. The current research adds several target specific elements in this framework, inclusive of barrier factors and paradoxical hesitation intention toward digital learning. Moreover, the current study unifies all elements and situations that emerge throughout the whole older adults’ digital learning process. The sequences from mechanisms how they are exposed to technology to classifying types of older adults’ digital learning behaviors are also analyzed thoroughly.
At this point, the research questions addressed are:
-
1. What is the major precursor of exposure to technology for the elderly?
-
2. Are there acceptance and barrier factors when it comes to senior digital learning?
-
3. Is it possible that older adults have paradoxical hesitation intention toward digital learning, in addition to having intention to use and having no intention to use it?
-
4. What are their perceived behavioral controls during the process of digital learning?
-
5. What are their actual learning behavioral types?
