I agree with Krashen that these variables are indeed important in learning for it happened to me in one of my subjects in high school. I don’t really like my teacher and I really hate to attend her class because I don’t like the lesson - paired with her monotonous voice and her poor teaching skills that’s why every time we’re going to meet her on that day I just feel terrible. I really have no motivation to study or to listen to her at all because she’s just reading the book and explaining it afterwards when every one
of us can do that. It is like she always comes unprepared or maybe that’s just really her way of teaching. Though I have self confidence in her class because it is just like a self study I still didn’t learn anything because I am always anxious for the class to end. I listened to her lessons but nothing really sticks. My mind can’t really absorb anything and even though I tried so hard to listen the next thing I know, my mind is already wandering somewhere else.
That is why we should take the ‘affective variables’ seriously because if a student have a low motivation, low self esteem and a high anxiety level the students will really have a hard time in learning. Not just the second language but applies to all of the subjects as well.
