I learned to use Dr.Racket to arrange pictures and numbers, do calculation and present change of numbers by vivid picture from lectures and projects. To be honest, I have no previous experience in programming, so almost everything I learned in this course was new to me. The most attractive part for me is "big bang". By programming, I can make pictures move as the way I designed. In addition, I can figure out how a picture is combined by colour dots. Last but not he least, I was introduced the development of computer and the Internet. I briefly heard about computers were much more expensive and slower back in just one decade, but I never thought about if I was born in fifty years ago, how my life would be like without having a computer. In this course, I witnessed the improvement in design and technology for computers from lecture notes, and actually felt the changes. Now I start being interested in computer programming and decide to take CSC108 in next semester.
For this course, I find that quizzes are not hard since they are directly from the video that we are supposed to watch. However, I felt it's challenging when I was doing projects, especially project 2. I knew what should I get, but I failed to write the expression at first. It took me about three hours to finish that project.
To sum up, I really enjoy this course and find programming is interesting.
