This document outlines principles for evaluating computer-assisted language learning (CALL) materials and tasks. It discusses five key principles:
1. CALL evaluation is dependent on specific contexts and situations, rather than providing definitive judgments of effectiveness.
2. CALL should be evaluated through both judgmental analysis of software/tasks and empirical analysis of learner performance.
3. Evaluation criteria should be based on theories and research findings about instructed second language acquisition.
4. Criteria must be applied considering the purpose of the CALL task.
5. Language learning potential should be the central criterion in CALL evaluation.
The document also provides examples of criteria for CALL task quality and questions to guide both judgmental and empirical
