Introduction
The advent of digital technologies and the growing presence of audiovisual media in everyday life have significantly transformed the educational landscape. The digitization of teaching materials, the proliferation of educational videos and the interactivity offered by multimedia tools affect teaching and learning practices. In this context, digital audiovisual media, which include not only videos but also animations, simulations and even virtual realities, become a valuable ally in education, enabling new ways of approaching content and stimulating students.
As Irene Machado argues in her analyses of the plasticity of audiovisual images, the electronic processing of sound and visual images creates cinematic spaces that introduce new perceptual and cognitive variants into teaching experiences (Machado, 2018). It is therefore fair to say that digital audiovisual technologies have helped rethink and reconfigure teaching methods and strategies, enriching the way knowledge is shared and built in classrooms.
In this text, I discuss the positive and negative aspects of using digital audiovisual media in educational contexts, addressing their potential and the challenges they raise. I then point to possible solutions and developments for the obstacles identified, highlighting examples that show the current and future impact of these technologies in education.
The Role of Digital Audiovisual in Educational Technologies
The potential benefits of digital technologies for teaching practices were raised with great enthusiasm in recent decades, but over time not all of them materialized as hoped. On the one hand, these technologies did make learning more dynamic, interactive and accessible in some contexts, although the panacea of global and equitable reach did not match reality. The versatility of audiovisual resources does allow many topics to be approached in a more playful and engaging way, making complex content easier to understand and stimulating different senses. In this way, digital audiovisual media contribute to sensory experiences that can enrich learning, but this requires adequate conditions and rigorous planning that prevents automatism and dependence on the part of the student. Therefore, the use of technology must be oriented toward the user’s creative practice and not merely toward the automated handling of the tool.
Irene Machado explores the notion of a “cinematic space” generated by the combination of sound and image, stressing that audiovisual media create an environment in which students’ perception and cognition can be expanded (Machado, 2018). This reinforces the idea that audiovisual resources make it possible to approach content in a multisensory way, making teaching more attractive and better suited to different learning styles.
Another positive aspect concerns the flexibility offered by digital audiovisual materials. Tools such as videos, animations, podcasts and virtual reality platforms can be used in many contexts, from traditional classrooms to distance learning. This variety of formats allows content to be adapted to students’ specific needs, fostering greater inclusion, for example for students with different skill levels or special needs (Silva & Meneses, 2023).
Interactivity is another central element, since digital platforms make it possible to create interactive videos, that is, a context in which students actively take part in building the texts, making decisions, answering questions or exploring different paths within the content. From a semiotic standpoint, this interactive approach aligns with Lotman’s (1990) understanding that exchange and interaction in the semiotic space of culture enhance the retention of information and the construction of knowledge by fostering a dialogue between agents and signs, here the student and the content, through multiple input channels and a multimedia environment that values different kinds of intelligence.
In addition, digital audiovisual media can help contextualize content, bringing theory into practical, everyday situations. Videos, for example, make it possible to demonstrate scientific experiments, recreate historical moments and present natural phenomena in a vivid and engaging way. In this way, students can be exposed to and visualize abstract concepts or phenomena far removed from their reality, which helps build new knowledge by establishing zones of translation where semiotic conflicts give rise to new meanings.
Digital audiovisual media thus offer, at least potentially, ways of enriching teaching, fostering more inclusive, sensory and interactive learning, while allowing greater flexibility in approaching content and helping students contextualize and better understand the concepts presented.
Despite the advantages digital audiovisual media bring to education, it is also important to consider some issues and concerns that surround them. Although audiovisual resources can enrich learning, they also pose challenges that must be addressed if their potential is to be realized.
One of the main problems relates to the excessive and indiscriminate use of these technologies. In some situations, audiovisual materials are used without proper pedagogical planning, which can result in a superficial or distracted experience for students. Instead of being tools that complement and deepen content, videos and animations can become mere entertainment devices that do not foster genuine knowledge building. For example, the frequent use of videos at school without the necessary context, or without room for reflection and debate, can lead students to consume information in an immediate way, oriented more toward entertainment than toward teaching and learning. This would run counter to the principles of active and critical learning and make it harder to consolidate knowledge in long-term memory.
Moreover, digital audiovisual media should not replace more interactive teaching practices, such as debates and group work, but should serve them. Depending on how they are used, they can limit student participation and inhibit the development of critical thinking. According to Lotman (1990), interaction is fundamental to the construction of meaning and to learning, but an excess of audiovisual media, or of any other resource, without proper mediation can limit the space for dialogue and reflection in the classroom. This is especially worrying in distance learning, where students’ isolation can be heightened by the absence of more human and less mechanical interactions.
Lotman argues that “semiotic space” is not made up of isolated elements but of constant relations and interactions between signs. He holds that living immersed in semiotic space also means living amid scattered information which, once organized as text, becomes culture. In this context, it is important to bear in mind that the classroom, the school, virtual learning environments and many others are semiotic spaces. Educational dynamics, therefore, are part of systems of cultural encounters and interactions between communication processes that are essential to the development of semiotic movements.
These relations foster dialogue and create an environment of transformation, in which information is translated, recoded and incorporated into culture, expanding its meaning. In other words, interaction is the mechanism through which the text of culture is constituted and transformed, and it is essential to the existence and evolution of semiotic space.
Another aspect that deserves attention involves accessibility and inclusion. Although digital audiovisual media can also be presented as an inclusive tool, depending on the context they can reinforce inequalities when they are not used equitably. Many students lack access to adequate electronic devices or good-quality internet, especially in remote regions or disadvantaged socioeconomic contexts. This can prevent all students from fully benefiting from these technologies and widen educational gaps. In rural or peripheral communities, for example, students often have to travel to public places, such as libraries, to access audiovisual materials, which can make it impossible to follow school activities regularly and independently.
Another problem concerns the superficiality and speed with which information can be consumed when there is no good planning. Audiovisual content, especially in digital environments, is often produced to be watched quickly, favouring a superficial understanding of the subject. The “short video” culture promoted by platforms such as TikTok and Instagram can lead students to expect that all information can be grasped quickly and easily, discouraging in-depth reading and the development of analytical thinking. In this context, complex materials such as long documentaries or detailed explanatory videos may be neglected in favour of shorter, more immediate content, which does not necessarily contribute to deep and meaningful learning.
In addition, an excess of sensory stimuli, such as sounds, moving images and visual effects, can harm concentration and the retention of information. Research in neuroeducation suggests that continuous exposure to intense audiovisual stimuli can result in “cognitive overload”, which makes it harder to assimilate content and consolidate learning (Silva & Meneses, 2023). In face-to-face classes, this can mean more distracted and less engaged students, while in virtual environments it can contribute to mental fatigue and lack of motivation.
So, although digital audiovisual media have the potential to enrich education, their excessive and indiscriminate use, lack of accessibility, the promotion of superficial understanding and sensory overload pose significant challenges. These issues point to the need for a careful, well-planned pedagogical approach so that audiovisual resources do not become an obstacle rather than a tool for improving education.
Possible paths and challenges
To deal with the challenges and concerns associated with digital audiovisual media in education, we need teaching strategies that promote a conscious and planned use of these resources, avoiding their negative aspects and enhancing their benefits. This requires careful selection of audiovisual materials and the creation of an interactive and collaborative learning environment that values dialogue and critical reflection.
One of the most effective ways of addressing indiscriminate use is to design lesson plans that integrate audiovisual media actively. Instead of using videos merely as a passive way of delivering content or illustrating concepts, teachers can turn them into objects of discussion and analysis. For example, in a science class on the brain, a documentary such as the BBC’s Brain Story, produced by
Sam Roberts and Alan Bookbinder, which explores how we think, feel and act, can be shown in parts, with strategic pauses for group debate and reflection. This practice encourages students to interpret the cultural signs presented and build meanings together, reaffirming Lotman’s view of the importance of interaction for the construction of meaning.
It is also essential that teachers act as mediators in the learning process, guiding students in understanding audiovisual elements. Activities involving critical analysis of the materials, such as identifying narrative elements, the construction of images and the use of the soundtrack, can help develop a deeper and more reflective reading of the content. In health-related classes, for example, showing a film adaptation of a literary work about plagues or diseases can be followed by activities that compare the visual language or narrative with the written text and the facts being studied, highlighting the points most relevant to the content.
Another path is to promote interactive videos and audiovisual tools that directly involve students in the creative process. Platforms that let students record and share their own videos can be used to encourage them to produce audiovisual content themselves. This active approach helps students better understand the concepts at hand, developing their communication and expression skills while encouraging autonomy in building knowledge. A practical example would be asking science students to produce short videos explaining experiments done at home with simple materials. This kind of activity reinforces theoretical content while fostering creativity and experimentation.
As for accessibility, it is important to implement policies that ensure all students have equitable access to audiovisual resources. This may include computer labs in schools and partnerships with public spaces, such as libraries and cultural centres, that offer free internet access and digital equipment. It is also important to provide alternatives to digital content for students who have difficulty accessing it, such as printed materials or activities that do not depend exclusively on technology. In distance learning, some initiatives have shown positive results, such as community support networks in which families and schools work together to share technological resources among students.
Regarding superficiality and sensory overload, one possible solution is to teach students to use audiovisual resources critically and consciously, that is, to promote media literacy. This can be done through activities that encourage the critical reading of audiovisual texts, a concept similar to the critical reading of written texts. Teachers can guide students to question the intentions of content producers, analyse how images and sounds are used to convey messages and reflect on how those messages affect their understanding of the world. In a class that considers media literacy, for example, students could analyse videos not only for their content but also for possible biases, identifying the persuasive strategies used and discussing how these strategies may or may not influence their perceptions and behaviour.
Another important path is to alternate audiovisual media with other teaching practices, such as debates, writing and group work. This multimodal approach helps avoid cognitive overload, since it allows students to process information in different ways and at different paces. In an ecology class, for example, after watching a video on climate change, students could be divided into groups to research local solutions to the problem and develop a presentation or an informative mural. This process integrates the knowledge gained through audiovisual media with other forms of expression and analysis, enriching the learning experience.
The key to addressing the challenges posed by digital audiovisual media in educational technologies therefore lies in the conscious and planned integration of these resources into teaching. By promoting active, critical and inclusive practice, it is possible to make audiovisual media a powerful ally for learning, preventing their potential from being lost to superficiality or inappropriate use.
Final Remarks
The presence of digital audiovisual media in the world of educational technologies opens the door to transformations and disruptions in traditional teaching and learning methods, but this is not a finished scenario. As discussed, these technologies can enrich the school environment, bringing new ways of approaching content and fostering interaction and meaning-making dynamically. However, their use clearly needs to be mediated by conscious and critical teaching practices if they are to contribute effectively to students’ overall development.
Looking ahead, digital audiovisual media are likely to keep expanding, following technological innovation and changes in how we communicate and learn. New tools such as augmented reality, virtual reality and artificial intelligence are already being incorporated into education, offering even richer and more interactive possibilities. These innovations, however, also bring new challenges and responsibilities. We will need teaching practices and educational policies that ensure accessibility, equity and students’ critical development, so that these technologies do not become mere entertainment or perpetuate existing inequalities.
Investing in media and digital education that prepares students not only to consume but also to produce and interpret audiovisual content with critical awareness is an essential condition in today’s educational context. This includes the ability to identify persuasive discourse, understand the effects of images and sounds in building narratives and analyse the ethical and social implications of technology in producing and disseminating information. In other words, audiovisual and digital literacy becomes as important as traditional textual literacy.
Moreover, as audiovisual resources are used more widely in education, the teacher’s role also changes. Teachers become mediators and facilitators of learning, guiding students as they navigate and interpret the vast sea of digital information and creating spaces for dialogue and reflection. This shift requires continuous teacher education, including mastery of new technologies and the development of critical and creative skills to apply them effectively and ethically in education.
From all this, it is clear that the impact of digital audiovisual media can be broad and multifaceted, pointing to an increasingly connected and audiovisual education. Although it poses challenges, its potential to transform teaching is undeniable, provided it is used consciously and directed toward building a truly interactive and inclusive learning space. The way forward requires a balance between enthusiasm for innovation and reflective criticism of its use, always with the aim of an education that forms citizens able to interpret, interact with and actively contribute to the world around them.
