This study explored the relationship between digital literacy and the online learning satisfaction of junior high school students and its internal mechanism. The results showed that the digital literacy of junior high school students was positively associated with their online learning satisfaction. The basic elements of teaching activities are teachers, students, teaching content, and teaching media. Most studies on learning satisfaction explore the influencing factors from the above perspectives. From the perspective of students, most previous studies have explored the effects of their learning attitude, motivation, and self-efficacy on online learning satisfaction [42][43][44]. However, different from traditional face-to-face learning in the classroom, online learning requires students to operate digital devices to complete learning tasks such as lectures, exercises, and homework. With the transition from face-to-face learning to online learning environments, students may feel ill-adapted.40 Students with high digital literacy have stronger network technical, cognitive, and social-emotional abilities. Therefore, in online courses during COVID-19, they can participate in online learning with high proficiency, thus generating higher online learning satisfaction.
The mediating effect of online learning engagement
The mediating effect results showed that online learning engagement played a partial mediating role in the association between digital literacy and online learning satisfaction. The effective use of information technology and digital learning resources can enhance learners' emotional, cognitive, and behavioral input by directly influencing multiple mediating factors, such as learning motivation and learning interest [45][23]. The results of this study confirmed the conclusion again and extended the conclusion to junior high school students. Students with high digital literacy are equipped with stronger abilities and qualities of acquisition, production, use, evaluation, interaction, sharing, innovation, security, ethics, and so on [46], so they can maintain online learning faster and longer, and increase engagement in online learning. Good information application ability is better reflected in the network learning mode, so students have a higher enthusiasm to participate in the network learning communication, and good "information awareness" helps students adopt a positive and proactive attitude to solve problems [47]. Online learning engagement has a positive connection with online learning satisfaction. The vigor, dedication, and absorption attributes of learning engagement can make online learners gain more positive emotions and academic achievements, and thus experience more online learning satisfaction.
Under the background of digitalization, many countries have introduced educational informationization policies to promote the upgrading and iteration of national education and realize the digitalized transformation of education. They make full use of information and digital means and focus on improving the digital literacy of educatees to promote all-around education transformation from the height of national strategies. For example, the National Education Technology Plan (NETP) released by the United States every four or five years since 1996, the Digital Education Action Plan (2021-2027) formulated and promulgated by the EU in 2020, and the Digital Agenda for Education 2023-2027 published by French in 2023 [48][49][50][51]. In the era of the digital economy, the cultivation and promotion of digital literacy will become the leader in developing students' core literacy. The results of this study also demonstrate the necessity of these measures at the micro level. The improvement of students' digital literacy is conducive to the improvement of online learners' learning engagement and online learning satisfaction, so as to promote the digital transformation of education. The healthy development of education will certainly promote the development of social politics, economy, and culture.
The moderating role of parents’ educational expectations
The results of the moderating effect test showed that parents’ educational expectations moderate the first half path of the mediating effect of digital literacy on online learning satisfaction. The association between digital literacy and online learning engagement is stronger for junior high school students with high parents’ educational expectations and weaker for vice versa. In other words, parents’ educational expectations enhanced the effect of digital literacy on online learning engagement, which confirmed the protective-enhancing model. Harrell and Bower point out that basic information literacy can improve the persistence of online learners, but with the improvement of learners' information literacy level, learners will reduce their attention to course content and learning tasks due to the interference of various activities in the network and thus tend to stop learning [52]. Adolescents who perceived high parents’ educational expectations had higher self-expectations for education [53]. Parents' educational expectations are reflected through their intelligence, energy, and economic investment in their children's education. Therefore, junior high school students with high parents’ educational expectations have clearer learning goals and stronger learning motivation in the online learning process during the pandemic, and will consciously apply good digital literacy to online learning rather than to other disruptive activities unrelated to learning tasks. Therefore, the results of this study once again verified the Rosenthal effect.
Implications
As mentioned above, prior to the COVID-19 pandemic, basic education students were not the main users of online learning, so most of the research on online learning was focused on college students. In order to effectively prevent the spread of the virus during the period of COVID-19, online teaching has been used to maintain the continuity of education worldwide in various degrees. As a new form of learning that spans time and space, flexibility, and ubiquity, online learning is an activity for students to learn through network communication technology or digital media. It has the advantages of resource sharing, information crowdfunding, behavior data, flexibility in time and space, relationship networking, etc., leading students' learning styles and growth paths [54]. In recent years, many countries have made considerable development and investment in digital learning technologies and online learning platforms [55]. In 2021, the Office of the Central Cyberspace Affairs Commission of China issued an Action Program to Improve Digital Literacy and Skills for All Citizens.46 Then, in 2022, China's Ministry of Education listed the strategic action of education digitization as an annual priority. Digital literacy is not only the core of skills in the 21st century, but also the foundation of lifelong learning in the digital economy era. Digital literacy and digital ability have become the core literacy and basic abilities of workers and consumers in the era of the digital economy [56]. Online-offline hybrid teaching will be an education mode that the world continues to explore and develop. Based on the results of this study, we suggest improving the digital literacy of junior high school students and attaching importance to the improvement and reasonable expression of parents’ educational expectations, so as to promote students' online learning engagement, increase online learning satisfaction, and achieve good learning results.
Limitations and future directions
There are also several limitations in this study. First, all variables were evaluated from junior high school students’ self-reports. In future studies, we should consider obtaining variables through the evaluation of parents, teachers, or classmates to reduce response bias and social desirability effects. Second, cross-sectional data cannot show the causality of variables. Experimental and longitudinal study strategies should be considered for use in the future to evaluate more accurate relationships. Third, this study was conducted in a sample of Chinese junior high school students that are reasonably homogeneous in culture, and future studies should extend the findings to different countries and regions.
