Vocabulary learning from the beginning:
Can the DTA evaluate beginner performance?
Immediate feedback is needed for optimal learning conditions. A computer is limited in what it can evaluate. But in a scene under its control, it can give feedback to support vocabulary learning and well up into the more advanced language skills.
The Empty Classroom
Off to learn a language
- We started here:
- Learning the vocabulary with AI. Two major cases. The DTA can provide an intelligent environment
Can DTA evaluate beginner performance?
- The DTA can present interactive scenes to give context for learning concrete vocabulary words,
- It can record and file learner responses.
- It can best support learning if it can evaluate the responses and give immediate feedback.
- Or if it can arrange for others to give the feedback.
- Conveniently, this feedback is only to support learning.
- It does not have to be recorded. It just has to happen. Indirect evaluation.

How the DTA can evaluate vocabulary learning
- For a vocabulary of concrete items:
- Task 1:DTA names an object in text and the learner to clicks on a digital representation of it. The digital object is scripted: it gives its name and a token telling what was clicked..
- Giving the name is immediate feedback to the learner and the token tells the DTA.
- Task 2: Like task 1, except that the name is given in voice. Evaluation is the same.
- Task 3: The DTA presents an object, learner types a name. DTA can test for match. If desired, DTA can apply tests for approximate match.
- Task 4: The DTA presents an object, learner speaks a name. DTA feeds the audio into a speech-to-text engine for the target language and evaluates the result.
Beyond vocabulary learning
- Direct evaluation
- Indirect evaluation (social only)
Assessment of reading comprehension (direct evaluation)
- The task is thoroughly investigated, many tests exist.
- You want comprehension to be the same as for the first language.
- So you assess comprehension in the target language.

- Scholarly articles for reading comprehension evaluation
Oral comprehension (direct evaluation)
- Apprentice level: The DTA gives audio instructions that the learners follow.
- The audio is recorded from native speakers.
- The DTA evaluates the actions as indicating comprehension.
- Journeyman level: Evaluation not available solo.
- Evaluated in conversation with experienced speakers. Indirect evaluation
- Apprentice level: Use a digital writing assistant like Grammarly
- Journeyman level: Indirect evaluation: learner writes instructions to others in target language.
- Direct evaluation by speech-to-text engine. The resulting text can be evaluated.
- Indirect evaluation: learner speaks instructions to others in the target language
- Create circumstances that cause other people to give feedback.
- That only works in the social mode. But language is inherently in the social mode.
