Many people, including some here, seem to recommend dictation on improving listening skills, but I wonder if the dictation is any more effective than just listening to the script and writing it in my brain. The reason I don't dictate is it is very difficult in my target language (Mandarin Chinese), as writing one word takes a few seconds (another hurdle is it requires environments such as a desk and pen). But my Chinese listening skills are quite stagnating...
Should I dictate it while listening? Or at least as long as I'm equally concentrating, is it no more effective? The content is usually 30 seconds or something like that. My Chinese is likely A1 or A2 (CEFR scale) on listening, though it would be B2 on reading.
