I'm new to programming, and I always have a so call difficulty, that is, I always tend to forget the thing (syntax, rules, name, definition or anyting) of a programming language I've learnt. And I personally do feel that the way I learn it is wrong. Here is my method. Everyday I will spend approximately 1 or 2 hours on a programming e-book. I just follow the syllabus and teaching inside the books, of course I have try to code myself, alter the code inside the book, and did the exercises available. But everytime right after I finish a chapter and advanced myself to third or fourth chapter, I will forgot something I learnt in the first chapter. Is it the method I use wrong? Does learning through reading and coding not enough? Do I need to everytime make a small note (mind map for example) of things I've learnt by hand writing? Or do I sometime need to try coding using a pencil and a book, but not a computer?
