Hwee Hwee's AFL on System of Marking Homework

My existing method of marking assignment is quite different from Hwee Hwee's new method. I will not give marks for each question, just a tick for correct working or cross for wrong ones. However, for wrong workings, I will give small tick to the line where the working is correct and then circle the next one where the student makes a mistake. In this way, the student is aware exactly what is wrong. Definitely some comments are necessary. I believe the AFL method of marking homework is better method to implement but will involve a little more time to just give marks tagged to each question. Will try to use this method for the next assignment onwards and see how it affects the student and our work.
