Video tape aided teaching interface with comparison logic - for tape-recorded signals and student responses to questions coordinated by logic circuits

摘要

The video tape carries teaching-learning sequences, questionnaires, interpretations and correction sequences whose starts and finishes are marked by specific signals identifiable by a pulse separator. The tape is held until the student has answered a number of questions by operating a pushbutton keyboard with numbered keys, YES/NO and/or TRUE/FALSE keys, erasure and confirmation keys. A logic function comparator then releases the tape at normal or high speed, identifying specific sequences which are either an interpretation of the answers introduced, or a correction, or the normal sequence of teaching-learning activity. The comparator may be more or less complex according the number of questions and signals envisaged, and a microprocessor may be used.
