Hi, I'm 張嘉軒 ! 

Or simply Jia, in case you don't speak Mandarin Chinese. I want to work at Busuu, for everything I do, I believe in challenging the status quo, in thinking differently. Being a part of an ambitious team that revolutionizes the way we learn languages, is simply my dream come true. During my years in the field of Teaching Chinese to Speakers of Other Languages (TCSOL), I realized the best way for us to tackle the problems while learning the language, is by making the content beautifully designed, easy to use and user-friendly. I just happen to have some wonderful ideas, and a clear vision to make them happen. Please scroll down for my CV, followed by the report especially dedicated to Busuu.

Active practitioner of bungy jumping, paragliding and parachuting (skydiving), which all connected to my deepest fear: heights. As someone who frets at the idea of being in a descending transparent elevator, I pushed myself to face it by practicing extreme sports. By pushing limits, one realizes how amazing life is, and that the sense of freedom lies in the tranquility of mindset itself.

Is revolutionizing the way people learn new languages throughout the world, gaining mutual understanding and eliminating bias and conflicts.

What's Missing?

Compared to Busuu's accomplishments in Indo-European languages, a comprehensive learning system of Mandarin Chinese for non-native speakers remains incomplete.


The use of Pinyin/Zhuyin

As the transitionary tools between utterance and sophisticated ideograms, as well as the "alphabets " for typing,  the introduction of Pinyin or Zhuyin is a must for every learner of Mandarin Chinese. Learners should be given the opportunity to compare the pros and cons of both of the tools, and choose whichever system that suits their needs from the start.


Simplified/Traditional Chinese Characters

  The ideas behind the construct of both characters are fundamentally different, as the former based more on replacement and pronunciation, and the latter more on history and meaning. Apart from it, the diversity of meanings in vocabularies throughout the Chinese-speaking communities ought to be recognized by our learners.


Development in CEFR Alignment 

For adult learners, the provision of C1 & C2 level courses remains absent. It is under these 2 levels that even the proficient users find the most difficulty in the implicit meaning embedded in this language (mostly from intuitive grammar and the background knowledge in culture); For younger learners, offering the Pre-A1 level will help to ease the process according to their early cognitive development.


Mandarin Chinese for Kids

When it comes to language learning, the context provides meaning, purpose, and a natural flow between the interlocutors, even more so for young learners, as they are relatively incapable of dealing with abstract ideas. By situating the material from the children's' angle, a great design of visual effects and highly interactive contents will fulfill the needs of being both educating and entertaining.


Differentiating Intonations  

As one of the greatest features of Mandarin Chinese, the nuance in tonal pronunciation could alter the meaning of a sentence completely in oral conversations. It is necessary to have tonal exercises integrated in every lesson until the level of B2, along with the possible liaisons when particular tones emerge.  


Slowing Easing into Chinese Ideograms

Chinese characters seem to be daunting at first look, and the thought of mastering the everyday 3,500 ideograms more like mission impossible. However, with a systematic method of arrangement, one could start from the basic "200 bricks" (from pictographic, indicative and associative characters), and build up a general comprehension throughout the rest with the lessons.

Why This Matters

Mandarin Chinese is the fastest growing language learning market in the world. In the UK alone, there has been a 40% growth per year since 2002 in middle schools, with numerous establishments listing Mandarin Chinese as one of their compulsory subjects. However, the development in Chinese-e-learning still lingers in an early stage, showing a huge untapped investment potential.

With every 5 people in this world, one of them is an active user of Mandarin Chinese. It has already been estimated to be the next world language after English. With celebrities such as Prince William, Mark Zuckerberg, and Herbert Hoover being able to give speeches with distinguished competency, it only stresses their recognition upon Chinese to be the language of the future.

According to recent financial analysts, by the year of 2020 China is expected to replace the United States in becoming the world's biggest economy. With the initiation of One Belt One Road (or B&R) and agreements in multilateral trade (TPPs), the economic influence will be a force to be reckoned with, as well as those who are equipped with such competitive advantage.

According to the latest report of PNAS, those who speak tonal languages such as Mandarin Chinese use both hemispheres of the brain rather than just the left, gaining access to the areas in charge of music and rhythm via the pitch and tone of the language. It is particularly beneficial towards the early development for younger learners by tapping into their cognition forming process.

Where to Start

The key towards a good design of a language learning app, is to activate the user's ability of self-learning, and to build up the features surrounding that goal. In the case of Mandarin Chinese, here are a few ideas which could result in a total make-over of Busuu:


Oral Abilities First

As Chinese characters are in nature logograms, they don't possess a direct link between pronunciation and production in the writing system, thus posing the greatest hinderance in learning especially for Indo-European speakers. The key of solving this problem is by cultivating the oral abilities first with Pinyin/Zhuyin from the early stage, then gradually introducing the initial "200 bricks" (mentioned earlier) when the learner has already enough vocabularies for everyday needs and a basic grammatical understanding of the language.


A Truly Customized Product

While learners may have different purposes while studying the language, the influence which their mother tongues cast over the learning process should also be taken into consideration. For example, people living in countries within the sinosphere (eg. Japan, Korea, Vietnam) comprehend Mandarin from character recognition, contrary to Indo-European speakers from pronunciation. Under such default, the design and layout of the product should be arranged accordingly based on the learner's abilities, utilizing their advantages instead of working against them.


Word Recognition over Production

According to researches the two abilities are very likely separate processes (especially for non-native speakers), and by mixing the two in materials the learning interest would not only suffer greatly but also not user-friendly. Based on modern-day habits, it is far more important to acquire the ability to be able to choose the right character in typing than the actual hand-writing, therefore in designs there ought to be different requirements as to the actual quantity for both competencies.


Cultural Tips Based on Language

As Mandarin Chinese is heavily embedded with its culture, it is essential to include background knowledge within every lesson to aid further comprehension. For learners in more advanced levels the provision of bite-piece idioms, two-part allegorical sayings, linguistic games, mini-sized historical stories, regional customs would cultivate cultural understandings while helping learners interact with native speakers in daily lives.


Busuu Dictionary

Mandarin as logogram has a very different concept in the construction of dictionaries. Each Chinese word could have its separate meanings while transform completely when paired with others. It is because of such linguistic feature that the Busuu character dictionary of Mandarin Chinese ought to include spelling, meaning, possible combinations, usage in sentences, as to stroke orders (how to hand-write them) and last but not the least, radicals (which category this character belongs to). 


Alignment with Standardized Tests

While learners may not study the language to pass the standardized tests such as HSK and TOCFL, they still hold valuable referential values by providing descriptions of each competency and vocabulary requirements for each level. For those who are in need of future immigration, academic progression, career advancement, or simply self-recognition, Busuu's alignment with large-scale standardized tests will separate itself from others in credibility in the market.

How did I encounter Busuu?

I started learning French about a year and a half ago. Back then, there wasn't a lot of materials to choose from apart from paper-based textbooks and French films/series which were still too difficult for beginners. By using Busuu I was able to accumulate my vocabularies on a daily basis, downloaded contents and study at odd moments. As a fluent speaker of Mandarin and English, I even helped others to correct their errors. Until one day, I was curious and switched to the Mandarin-learning section and discovered the possibility to contribute to your future.
