In the era of widespread access to the Internet and mobile applications, more and more people are choosing to learn a foreign language using modern technologies. The COVID-19 pandemic further accelerated this process – many people who had previously learned exclusively in the classroom discovered the potential of online learning. What’s more, companies – especially international ones – are increasingly looking for scalable, easily accessible solutions for their employees around the world. It might seem that educational platforms are the perfect answer to these needs. But can they really replace a teacher?
In this article, we compare three main language learning models:
- Platforms with ready-made educational materials (e.g. Duolingo, Babbel, Rosetta Stone, VOCAbite, Busuu),
- Platforms offering quick on-demand contact with a teacher (e.g. italki, Preply, Verbling),
- Individual learning with a teacher tailored to the student, supported by a language platform – the model implemented at our language school.
- Self-study on platforms – convenience or an illusion of progress?
Platforms such as Duolingo or Rosetta Stone offer users access to a vast database of interactive materials – from vocabulary exercises and grammar to short tests. Their biggest advantage is accessibility – you learn whenever you want, wherever you want, without scheduling lessons with a teacher. Gamification and daily reminders are designed to motivate users to study regularly.
Recently, many platforms have also introduced an additional feature that partially replaces the role of a teacher – a chat function that allows you to talk as if with a teacher, and even assign role-plays to practice language skills in specific contexts (for example, a job interview or a business meeting). Such features are available on platforms like VOCAbite, Preply, italki, and Duolingo.
Advantages:
- low cost or completely free access,
- learning anytime and anywhere,
- interactive learning formats, short “bite-sized” lessons, a micro-learning approach.
Disadvantages:
- lack of personalization – materials are universal and often not suited to the learner’s level or needs,
- mainly passive skills are developed (reading, listening),
- lack of real interaction and speaking practice,
- content can be chaotic and sometimes even incorrect, leading to the learning of wrong forms – as noted by one of our interviewees, a Duolingo user learning Russian.
- Platforms connecting students with teachers – flexibility with limitations
Another model includes platforms such as italki, where you can connect almost instantly with a teacher – a native speaker or a professional instructor. This solution is particularly attractive for those who want to practice speaking in a less formal way than traditional classes.
Advantages:
- a wide selection of teachers and languages,
- the ability to adjust lesson times to your own schedule,
- contact with real-life language and authentic accents.
Disadvantages:
- significant differences in teachers’ competencies – you don’t always work with a professional; often people teaching the language know it well but are not qualified teachers, which may not suit some users,
- lessons are often quite standardized, sometimes prepared centrally by the platform, which limits the ability to tailor materials to the specific needs of an individual student,
- lack of a long-term learning plan and continuity – “on-demand” classes are difficult to organize into a coherent course, especially when they are taken occasionally with different teachers.
It is also worth mentioning hybrid solutions such as the Tandem app, where you can chat with users from around the world – sometimes for free, sometimes for a fee. It’s a great way to “immerse yourself” in the language, but without structure and methodological support, it can quickly lead to frustration.
- Individual learning with a teacher – a personalized path to your goal
At our school, we focus on a model in which a teacher guides the student through the entire learning process – from defining goals, through selecting materials, to regular evaluations. This approach works particularly well in business language learning – where not only linguistic accuracy matters, but also cultural, industry-specific, and functional context.
Advantages:
- a program tailored to the individual needs and goals of the student,
- regular contact with the teacher and ongoing adjustment of pace and content,
- the opportunity to practice active skills – speaking, writing, arguing, participating in discussions, etc.,
- methodological support and feedback that no automated system can provide,
- if lesson work is supported by independent study on a platform, progress is faster and allows for active practice with the teacher during lessons using previously mastered vocabulary or grammar. This is a key feature of the blended learning method.
Disadvantages:
- higher cost compared to apps alone,
- the need to adjust your schedule to the teacher (classes are held online, which increases flexibility).
What do users say?
In our 2022 market research, platform users emphasized that although they were initially enthusiastic about the possibility of learning “in between tasks,” over time they began to miss interaction, structure, and motivation. Automation and repetitive content stop being sufficient when there is a need for real conversation or using the language at work.
Summary – what should you choose?
It all depends on what stage of learning you are at and what your goals are. If you want to learn the basics before a trip and have a lot of internal motivation – an app may work well. However, if you are learning to conduct business meetings, presentations, or negotiations – no automated system can replace an experienced teacher.
It’s also worth remembering that these methods do not have to exclude each other. The ideal solution may combine the flexibility of a platform with the engagement and expertise of a teacher. Platforms are a good solution when, for example, you can devote only one hour per week to lessons with a teacher – in that case, working on a platform allows you to stay in contact with the language outside of classes.
Below is a comparison table of currently popular platforms, along with their advantages and disadvantages.
