Applying ChatGPT to tackle the side effects of personal learning environments from learner and learning perspective: An interview of experts in higher education

This paper investigates the capacity of ChatGPT, an advanced language model created by OpenAI, to mitigate the side effects encountered by learners in Personal Learning Environments (PLEs) within higher education. A series of semi-structured interviews were conducted with six professors and three Information and Communication Technology (ICT) experts. Employing thematic analysis, the interview data were assessed, revealing that the side effects stemming from the learner and learning perspectives could be primarily categorized into cognitive, non-cognitive, and metacognitive challenges. The findings of the thematic analysis indicate that, from a cognitive standpoint, ChatGPT can generate relevant and trustworthy information, furnish personalized learning resources, and facilitate interdisciplinary learning to fully actualize learners’ potential. Moreover, ChatGPT can aid learners in cultivating non-cognitive skills, including motivation, perseverance, self-regulation, and self-efficacy, as well as metacognitive abilities such as self-determination, self-efficacy, and self-regulation, by providing tailored feedback, fostering creativity, and stimulating critical thinking activities. This study offers valuable insights for integrating artificial intelligence technologies to unleash the full potential of PLEs in higher education.


Introduction
Personal Learning Environments (PLEs) is an educational approach that enables students to utilize social media to enhance self-regulated learning in both formal and informal pedagogical settings [1,2].The purpose of PLEs is to equip students with the ability to organize the resources, social interactions, and information produced in the teaching-learning process [3,4].Research has found that there is a correlation between the use of PLEs and improved student autonomy and decision-making capacity, which can reduce reservations in performing tasks [5].Additionally, self-efficacy, a malleable element [6], can be enhanced over time through the use of virtual or traditional tools and strategies integrated into PLEs.
However, the development and implementation of PLEs can result in unintended negative consequences, referred to as side effects.These side effects can have an impact on both the learners and the learning process, leading to reduced learning outcomes or hindering the achievement of educational goals.Recent literature has identified various forms of side effects in education, including distractions, information overload, and reduced interaction between learners and teachers caused by the use of technology in the classroom [7,8].Similarly, challenges related to privacy, data security, and learner autonomy can arise from the implementation of PLEs [9,10].Pedagogical approaches can also create side effects, such as anxiety, stress, and academic disengagement caused by the use of high-stakes testing or competitive grading systems [11,12].
To mitigate the potential side effects of PLEs, we aim to explore how ChatGPT, a language model that provides personalized responses to learners, can address the potential side effects of PLEs from the learner and learning perspective.We plan to conduct interviews with experts in higher education to discuss the potential side effects of PLEs, the benefits of using ChatGPT, and how it can enhance the learning experience.By doing so, we hope to provide insights into how AI technologies such as ChatGPT can be leveraged to improve the effectiveness and efficiency of PLEs while minimizing potential side effects.

Concept and development of Personal Learning Environments (PLEs)
Personal Learning Environments (PLEs) provide learners with the ability to create and share their own content, work collaboratively with others, and access resources from anywhere and at any time through incorporating different digital tools and resources, such as social media, blogs, wikis, and other web-based applications.PLEs offer a flexible and dynamic learning experience that can be tailored to suit the needs and interests of individual learners, resulting in increased engagement and improved learning outcomes.According to Castañeda's [13] analysis of the PLE literature published during the period 2010-2020, two critical areas of research have emerged: pedagogical practices and self-regulated learning.The notion of PLEs has been linked with the creation of innovative learning models that challenge traditional educational structures and prioritize the learner, granting greater autonomy and placing them at the center of the learning process.In this regard, teachers are viewed as facilitators and guides.Meanwhile, research on self-regulated learning suggests that PLEs is primarily examined from a pedagogical perspective, albeit with subtle variations.Moreover, digital tools, and Web 2.0 services are considered as instruments for learners to manage their learning and enhance cognitive skills associated with self-regulated learning.

Side effects of PLE in higher education from a learner and learning perspective
Studying the side effects of education is crucial for providing learners with an optimal educational experience.Metcalf [14] research suggests that understanding the potential negative consequences of educational interventions can help educators and policymakers make informed decisions about the design and implementation of educational programs.In terms of the side effects of PLEs, one of the primary challenges identified is the integration of PLEs with formal learning management systems (LMS).This challenge arises due to the differences in structure and functionality between PLEs and LMSs, which may lead to issues with interoperability and data exchange [1].Kop and Hill [15] identified the gap between individuals with access to digital technologies and those without, as well as the quality and reliability of the information available within PLEs.Fiedler and Va ¨ljataga [16] highlighted the challenge as the lack of a clear and consistent definition of PLEs.Blaschke [17] discussed the challenge of incorporating social media into existing formal educational systems.Wilson et al. [18] addressed the issue of control and ownership of learning within PLEs.While PLEs aim to empower learners by giving them control over their learning experience, this may conflict with traditional educational systems, where control is often held by institutions and educators.
From the learner and learning perspective, this research reviewed the side effects and challenges of PLEs, and summarized them into the following three categories: cognitive skills, non-cognitive skills, and meta-cognitive skills.Regarding cognitive skills, learners require sufficient digital literacy to use PLEs effectively.For instance, Lee and Meina [19] and Attwell [20] suggest that keeping up with new technologies and developing necessary digital literacy skills can be difficult for learners due to the fast pace of technological change.Furthermore, the abundance of information available online can be overwhelming, making it challenging for learners to distinguish credible sources and effectively utilize digital tools [1,15].
In terms of non-cognitive skills, it includes motivation, perseverance, self-regulation, and self-efficacy.According to Kim [21], learners' motivation and emotions are critical factors for success in PLEs.However, effectively measuring and utilizing non-cognitive skills in PLEs remains a challenge.Routledge, Humphries and Kosse [22,23] notes that non-cognitive skills are difficult to measure and develop, which poses a challenge to their effective utilization in PLEs.
As for meta-cognitive skills, it includes self-determination, self-efficacy, and self-regulation, which involves setting personal learning goals, selecting and organizing resources, and evaluating their learning outcomes.Learners who lack these skills may face difficulties in managing their PLEs effectively [16].Rodman [24] suggest that PLEs require learners to be proactive in their learning, taking ownership of their learning outcomes.Developing learners' self-efficacy is another critical challenge in PLEs.Jeske et al. [25] argue that learners must feel confident in their abilities to succeed in a personalized learning environment.Lastly, learner self-regulation and management of Web 2.0 tools pose challenges in the development and implementation of PLEs.Lim and Newby [26] highlight the importance of learners' self-regulation in the effective use of Web 2.0 tools, emphasizing the need for learners to manage their online learning activities effectively.
To succeed in PLEs, learners need to have a range of cognitive, non-cognitive, and metacognitive skills.While digital literacy, motivation, self-regulation, and self-efficacy are important for success, developing and utilizing these skills effectively can be challenging for both learners and educators.

Methods
The study received approval from the Wenzhou University Review Board, bearing the approval number IORG/IRB #202303.For data collection, online semi-structured interviews were carried out during 20-27 February, 2023, utilizing the Tencent Conference platform.The interviews were conducted in English and lasted between 25 to 30 minutes.Following their participation, each interviewee was sent a letter of appreciation acknowledging their valuable contribution.Throughout the research, the team was deeply conscious of ethical standards and was committed to upholding them.Before proceeding with interviews, written informed consent was secured from every participant via email, reflecting our commitment to respecting their choices.Strict confidentiality was maintained regarding the participants' information, ensuring their anonymity and privacy.Their data was handled with utmost discretion, and their identities were never mentioned in any resulting publications or reports.
