GreenwayIntegration of Quality Assurance Issues for Higher Education 4 Factors to Consider when Teaching VAM The information must be interesting, relevant and correct The teacher must be completely committed to VAM Mathematical concepts should be introduced gently QA and Quality Control (QC) are not concepts restricted to analytical measurements
