German Physicist Launches, an Advanced Online Vocabulary Building Tool for Language Learners

Frustrated with the inability of traditional flashcard-style, language-learning tools to support his desire to learn Japanese over a lifetime, German physicist Dr. Marc Busch launches, an advanced online learning support portal.

The way Dr. Marc Busch tells it, there has been for far too long a gaping hole in the tools that exist to help people learn languages and build vocabulary., Dr. Busch's brainchild and newly launched online language learning support portal, fills that hole. The newly launched portal allows language learners, classmates, teachers, families and friends to study content individually or collaboratively by forming online study groups; by creating, importing and sharing word and data lists online; and by monitoring the learning progress over time. members pay as they study, in three-month increments, allowing for even very long gaps in study as so often happens in life. also addresses several critical issues common with traditional flashcard-style learning tools.

"There are two major issues people run into when using flashcard-type tools to help them learn a language," says Dr. Busch. "First, flashcards alone can not account for the unique learning history of each word--the cards can not 'know' whether it took you a long time to learn the word because it was difficult for you, or whether you learned it was easy for you and quickly learned. Second, flashcards do not account for our tendency to forget over time. If you come back to your flashcard box system after not studying for an entire year, like I did when I was studying Japanese, you will find that the box represents your learning from a year ago, when you last studied. It does not truly represent what has been going on in your mind.", leveraging computer power and a sophisticated algorithm, resolves those issues. The system considers how a learner learns each flashcard item, the passage of time and a learner's tendency to forget. "In Comprehencia, your flashcards are always in motion," explains Dr. Busch. "The total word pool changes every second based on how you learned each word or item and how long it has been since you last studied. reflects and adapts to the changes in your mind, even when you are not studying."

According to Dr. Busch, it is Comprehencia's ability to store and reflect a learner's whole learning history over time--even over a lifetime--that sets his language learning portal apart. "I believe that anyone who has ever spent time learning a language only to have to start over again from scratch after a lengthy pause will appreciate what Comprehencia offers," he explains. "Use it for a year--take a break--and when you come back you will not have to start again from scratch. Comprehencia lets you continue your learning over the whole of your life."

About Comprehencia

Dr. Marc Busch has spent the last few years working in industrial research and has headed up a number of international projects in the fields of molecular imaging and computer visualisation. In his spare time, Busch enjoys learning all about Japan and the Japanese language. His own frustrating experience with the many Leitner-type flash card programs gave him the impetus to start Comprehencia in August 2007. The object of the program was to develop an algorithm which can realistically model the state of knowledge of the learner even after fairly long learning breaks. The result of this research is the online portal, where learners all over the world can use this algorithm for their own language studies.
