Using genuine learner performance data for the
assessment of language ability
As web-based and web-enhanced computer technology provides more widely available tools for language learning and teaching, existing technologies such as screen capturing applications should be used for continuous performance assessment. The strategic use of computerized data gathering capabilities can more accurately inform second language teachers, testers, and researchers.

What we know
• Feedback– Nagata, 1993 (intelligent feedback)– Liou, 1993 (drawing attention to errors)– Cardelle & Corno, 1981 (effects on second
language learning of variations in written feedback on homework assignments)
– More recent examples dealing with feedback all on handout
What we know
• Modification of input– Plass, Chun, Mayer, and Leutner (1998) – Chun and Plass (1996) – White (1998)
– Move refs to handout
So, we know that …
• Feedback is important (particularly constructive negative feedback)
• Opportunities for input modification can enhance language learning
What we do
• Example of a non-native speaker arriving at a university in the U.S.– English Placement Test (EPT) Placement into writing class
• Diagnostic Test• 3-5 essays• Vocabulary assignment• Journal assignment• In-class tasks
Tests Evaluation Feedback to students Input Modification
EPT Holistic None You have to take English
101
None
“Diagnostic” Holistic NoneYou have to stay in this
course
None
Class work
3-5 essays, maybe a research paper
Holistic, possibly rubrics In-class, peer editing, draft comments,
Possible
Vocabulary assignment Quantitative and qualitative Some Varies, possible
Journal assignment Holistic, Some, primarily comments on content
None
In-class tasks Varied Some Possible, use of online resources and activities
What we should/could do
• How can we inform students, teachers, and researchers?
CALL is ideally suited for:– Providing opportunities for input
modification– Providing automated, performance-related
feedback– Tracking student performance
Input modification opportunities
• Implementation easier with computer technology – LCTL– Example with overlib.js– Example with Flash (D. Russell) – Example of access to concordancers (and
more): Tom Cobb’s Compleat Lexical Tutor (screenshot)
Placement essay project
• Essay
• Mark-up
• Feedback
• End product: database of student essays, marked up, accessible and searchable by grammatical problem
Access to placement essay project
• Students will be able to search by grammatical problems and native language and will have the opportunity to – look at the error – the suggested solutions– suggested sites to address the problem
Tracking possibilities
• Wishful thinking? 1 2
• Two sample report cards
• Camtasia example
• Software (DynEd)
