With over 1300 lessons in Praxis’s signature format (dialogue, vocabulary, expansion, exercises), we’ve got a lot of lesson data to work with. For over a year now, the Praxis Language tech team has been reworking the system architecture behind the scenes to enable more powerful applications of that data. This week we are releasing ChinesePod’s new Placement Test and Level Test.
Both tests offer the following features:
- Random selection of questions, drawn from the data of over 1300 lessons
- Choice of simplified or traditional characters (defaults to your lesson settings)
- Short, medium, or long test lengths
- Partial saving of the test, just in case you get interrupted (answers are saved when you go to the next page of the test)
- Total breakdown at the end, showing how you did on the different question types, across the different levels
- “Virtual test paper” showing your answers, with the ones you got wrong marked wrong and the correct answers highlighted
- Test results are automatically saved, giving you a history of your progress (for this reason, you must also be a registered user to use the new testing functionality)
Placement Test
The Placement Test replaces ChinesePod’s former Listening Test. The test takes a random sampling of lesson data from all lessons, in even distribution across the various levels, and then presents them in random order. Initially, there are only two sections of the test: multiple choice and dictation.
Dictation is definitely a challenge; there is no partial credit. This means any mistyping of 的, 得, or 地 will get the whole sentence marked wrong. Fortunately, the system will intelligently allow for “tā” in the audio to be entered as “她” (she) or “他” (he), accepting either character. Still, you won’t find this section easy!
Your final percentage will place you approximately in one level range. Adjustment is made for potential correct guesses in the multiple choice section (which is why the “Newbie” result area is the largest), which is partially moderated by the dictation section, where guessing is impossible. Scores are automatically recorded.
Level Test
Similar to the Placement Test in format, the Level Test draws from only one difficulty level. This has a number of applications, such as confirming that you have mastered the content of a certain level, or testing your readiness for the content of a higher level.
Note that because ChinesePod lesson content overlaps to some extent within each level, you need not study every lesson to master most content of that level. (For example, you may be able to score in the high 90’s on the Newbie Level Test after studying fewer than 100 lessons, even though there are more than 300 Newbie lessons in the archive.)
The Future
These tests mark the beginning of ChinesePod’s greater efforts at quantitatively measuring an individual’s progress in Chinese. We hope you’re as excited at the implications these tests represent. These two tests, while useful as they are, represent just the very beginning of what can be done with lesson data. In the future, expect better question types, a more intelligent testing engine, personalized testing data selection, and more…
Threaded Comments on ChinesePod
As promised previously, we have managed to finish the much-anticipated threaded comments feature before the end of 2009. The ChinesePod community has been asking for this feature, and we are pleased to present this big step forward for the community.
First, we have drawn a lot of inspiration from the site Yammer, which does a great job managing a company’s conversations in a Twitter-like interface. The ChinesePod community is no Twitter, however, so ours is a custom solution. The upgrade is actually a small collection of new features:
Please let us know if you have any questions or comments!
And happy New Year! 新年快乐!
UPDATE: Despite extensive testing, the new code to support threaded comments seems to be significantly slowing down lesson page loads. We certainly don’t want the site going down over the holiday, so we’ll be pulling the new feature until early next week. Sorry for the delay!
