  Outlines: • What isinformatics? • Educational informatics • Applications • Advantages • Disadvantages
• 3.
  Informatics • Informatics isthe study of the structure, behaviour, and interactions of natural and engineered computational systems.
• 4.
  Educational Informatics • Itis a sub-field of informatics. • The primary focus is on the computer applications, systems and networks that support research in and delivering of education.
• 5.
  APPLICATIONS • MOOC • E.g.udacity, coursera, edx, mitopencourseware etc. • Google Classroom • Smartphone Apps • E.g. phrasal verb machine made by Cambridge university press etc.
• 6.
  Advantages: • shared data; •centralized control; • disadvantages of redundancy control; • improved data integrity; • improved data security, and database systems; and, • flexible conceptual design.
• 7.
  Disadvantages • a complexconceptual design process; • the need for multiple external databases; • the need to hire database-related employees; • high DBMS acquisition costs; • a more complex programmer environment; • potentially catastrophic program failures;
