Within the traditional “teacher-textbook-student” triad, the textbook serves as the core carrier of knowledge, and the classroom functions as the primary site for knowledge transmission. However, in an era where “digital natives” constitute the main student body, static, linear printed textbooks and the model of one-way knowledge transmission in classrooms are increasingly inadequate for cultivating students’ core competencies and innovative abilities ([4]). The development of digital textbooks and digital classrooms signifies far more than the simple introduction of technological tools or a shift in media; it represents a systematic reconstruction concerning educational philosophy, teaching models, and evaluation systems. Its aim is to build a new, open, interactive, precise, and personalized learning ecosystem. Therefore, clearly understanding the profound role of digital textbooks and systematically planning the construction path for digital classrooms represent a pressing issue requiring in-depth research in current educational reform.

Three-Dimensional Value Beyond “E-books”. Digital textbooks should not be simply regarded as PDF files loaded with multimedia resources. Their core value is reflected in the following three dimensions:

Digital textbooks are far more than simply digitized versions of printed content. They are comprehensive learning platforms that integrate text, images, audio, video, animations, interactive exercises, and expansive hyperlinks. For both teachers and students, leveraging these features effectively is key to unlocking their immense potential.

For teachers, digital textbooks are innovators in instructional design and classroom management:

Building Contextualized and Personalized Classrooms: In traditional classrooms, explaining abstract concepts can be time-consuming and laborious. Digital textbooks, however, allow teachers to call up high-definition satellite images for geography, play historical footage to recreate the past, or use 3D models to dissect human organs. This vastly enriches the dimensions of teaching, making knowledge tangible and accessible. Furthermore, teachers can use the built-in tiered exercises and resource libraries of digital textbooks to create differentiated lesson plans based on the overall level of the class, catering to the diverse learning needs of all students.

Enabling Precision Teaching and Assessment: The learning management systems that accompany digital textbooks can record real-time data on student reading duration, quiz performance, knowledge gaps, and more. By analyzing this data, teachers can quickly identify common class-wide issues and individual weaknesses, allowing for targeted feedback and tutoring. These shifts teaching from being “experience-driven” to “data-driven,” achieving a new level of precision.

Fostering Collaborative Inquiry and the Flipped Classroom: Teachers can use the digital textbook platform to assign group research tasks. Students, focusing on a specific topic, can use linked resources both within and beyond the textbook to gather information, organize it, and collaborate on projects, thereby cultivating critical thinking and digital literacy. Additionally, digital textbooks are ideal tools for implementing the “flipped classroom” model. Students acquire foundational knowledge before class by watching videos and completing basic exercises, freeing up class time for in-depth discussion, project-based exploration, and personalized guidance, truly realizing a “student-centered” approach.

For students, digital textbooks are boosters for self-directed learning and skill development:

Creating Personalized Learning Pathways: Students are no longer passive recipients of uniform information. They can selectively delve into supplementary materials based on their own interests and comprehension, re-watch videos explaining difficult concepts, or skip content they have already mastered. This partially returns the initiative for learning to the students, fostering self-directed learning abilities.

Using Interactive Features to Deepen Understanding: Instantly submitted exercises, drag-and-drop chemical molecular models, simulatable physics experiments... these interactive features provide immediate feedback, enabling students to “learn by doing,” consolidate knowledge through trial and error, and transform abstract theory into concrete experience.

Constructing an Interconnected Web of Knowledge: Through hyperlinks and prompts for related knowledge points within digital textbooks, students can easily connect old and new knowledge, as well as concepts from different disciplines. For example, while studying a classical Chinese text, they can access links about the author’s life, relevant historical context, and later literary critiques, thereby building a multidimensional, interconnected knowledge system rather than just accumulating isolated facts.

Based on the aforementioned characteristics of digital textbooks, the construction of digital classrooms is a systematic project. We propose a four-layer integration model. It is crucial to note that the successful implementation of this model hinges on two fundamental preconditions at the institutional level. First, strong and sustained institutional support is required for top-level design, including the development of a clear digital strategy, investment in interoperable technological infrastructure, and the establishment of data governance policies that protect student privacy. Second, a robust, ongoing teacher training program is indispensable. This program must extend beyond mere tool operation to encompass the pedagogical redesign of lessons, data interpretation skills, and strategies for fostering the classroom community layer outlined below.

The construction of digital textbooks and classrooms is not without challenges, primarily facing four major hurdles:

Mindset and Capacity Challenges: Teachers may face “technophobia” and “insufficient design capability.”

Countermeasures: Conduct sustained, tiered, case-led teacher training, and establish cross-disciplinary teacher communities of practice to encourage collaborative design and experience sharing.

Resource and Technical Challenges:Risks of “information silos” and the “digital divide” exist.

Countermeasures: Schools need to strengthen top-level design, promote the interoperability of platforms and data, pay attention to disadvantaged student groups, provide necessary equipment and network support, and ensure educational equity.

The Risk of Over-Datafication:The heavy reliance on learning analytics may lead to an overemphasis on quantifiable metrics at the expense of holistic education. This can raise significant student privacy concerns and potentially narrow the curriculum, as teachers might feel pressured to “teach to the metric”—focusing only on what is being measured (e.g., quiz scores) while neglecting harder-to-quantify skills like creativity, collaboration, and critical thinking.

Countermeasures: Establish strict data ethics and privacy protection guidelines, ensuring transparent data collection and usage policies with informed consent. Furthermore, professional development should guide teachers to interpret data as formative and diagnostic tools, not as definitive judgments of student worth. The evaluation system itself must be reformed to balance quantitative data with qualitative assessments, such as portfolio reviews and project-based evaluations, to present a complete picture of student growth.

Evaluation and Management Challenges: Traditional evaluation systems struggle to measure higher-order competencies and collaborative spirit in digital classrooms.

Countermeasures: Reform teaching evaluation standards, emphasize process data, and introduce diverse evaluation methods based on portfolios and performance tasks.

The Path to Integration: Digital as the Tool, Tradition as the Foundation

While embracing digital textbooks, we must clearly recognize that technology is always a tool, and the core of education is “cultivating people.” The valuable heritage of traditional teaching—what we might call “traditional knowledge”—should not be discarded, but rather imbued with new vitality in the digital age ([5]).

Firstly, the capacity for deep reading and systematic thinking requires a return to “tradition.”

The fragmented information and diverse presentation styles of digital textbooks can easily lead to scattered attention and superficial thinking among students. Here, teachers should consciously guide students toward “deep reading.” ([1]) For instance, after using digital resources for background learning, require students to return to the pure text for annotation, excerpting, and reflective writing. A specific pedagogical strategy to facilitate this is “Guided Annotation,” where the teacher provides students with a digital text embedded with prompts and a dedicated digital notebook. Students are instructed to not merely highlight text, but to use a consistent set of symbols or comment tags (e.g., ([1]) for questions, ([7]) for key insights, ([6]) for connections to other knowledge) to mark the text. They are then required to elaborate on these annotations in their digital notebook—for example, explaining why a certain point is crucial, or formulating a specific question about a confusing passage. This structured process transforms passive reading into an active dialogue with the text, slowing down the cognitive process to foster critical analysis and retention. This process of deep engagement with the text is crucial for developing logical reasoning, critical thinking, and linguistic sensitivity—things no technology can replace.

Secondly, the value of writing by hand and engaging both mind and body is irreplaceable.

Writing Chinese characters is not just a skill; it is a form of cultural and cognitive training. In subjects like mathematics and physics, the process of manually working through calculations and derivations embodies the organization of thought and logical rigor ([10]). Teachers should encourage students to use traditional note-taking to consolidate knowledge frameworks after learning with digital textbooks, and to use pen and paper for complex calculations and compositions. Neuroscience shows that handwriting activates broader regions of the brain, aiding memory consolidation and knowledge internalization.

Thirdly, teacher-student interaction and emotional connection are the soul of education.

No matter how intelligent a digital textbook is, it cannot replace a teacher’s encouraging glance, a reassuring pat on the shoulder, nor can it replicate the spark of intellectual collision in group discussions or face-to-face debates. Teachers should use the class time saved by digital textbooks to organize more group activities, thematic debates, role-playing, and other activities requiring high levels of interpersonal interaction. Technology should serve to deepen the connections between people, not become a barrier.

Finally, the ancient wisdom that “practice yields genuine knowledge” is never obsolete.

No digital simulation, however, realistic, can fully replicate the awe of hands-on instrument calibration and observing chemical reactions in a lab; no virtual museum tour, however clear, can match the experience of standing before an artifact and feeling the weight of history. Digital textbooks should act as a bridge connecting the classroom to reality, inspiring students to go out, observe, practice, and create. As shown in Figure 1.

Digital textbooks are the “intelligent engine” activating digital classrooms, while digital classrooms are the “practical field” for realizing the value of digital textbooks, shown in Table 1. The deep integration of the two is driving education

from “standardized production” towards “personalized growth.” The future educational landscape will be a smart learning environment where digital textbooks serve as a key hub, integrating physical space, social relationships, and digital information. Educators should proactively embrace this transformation, starting by building a solid resource foundation, using innovative teaching activity designs as the engine, navigating with data intelligence, and ultimately fostering a vibrant learning community, thereby laying a solid foundation for cultivating innovative talents adapted to future society.
