Syntax Untangler is an online activity that asks the learner to visually mark up a short primary text in any language, in order to improve small-scale reading skills. Any instructor can easily create and publish their own Syntax Untangler content (go to the Instructor Tools link below).
Syntax Untangler is particularly designed for training language learners to recognize and parse linguistic features. Here are some things you could ask your students to do:
Identify the parts of a separable-prefix verb within a German sentence.
Draw where a syntax structure begins and ends in a short Chinese text.
