What fun is there in making plans, What fun is there in making plans, acquiring discipline in organizing acquiring discipline in organizing thoughts, devoting attention to detail thoughts, devoting attention to detail and learning to be self-critical? “ and learning to be self-critical? “

4. Critical Skills – Analysis – Critical Thinking – Attention to Detail

5. Design Recipe To design a program properly, we must: – Analyze a problem statement, typically expressed as a word problem expressed as a word problem – Express its essence, abstractly and with examples examples –Formulate statements and comments in a precise language precise language –Evaluate and revise the activities in light of checks and tests checks and tests

6. – PAY ATTENTION TO DETAIL – These skills are useful for anybody anybody – All assignments in this course should follow the these should follow the these guidelines guidelines
