Strategies of learning a language

I found out an interesting Youtube channel talking about the ways to learn English. The videos and then I watched almost all its the videos which have given gave me a lot of inspiration.

To improve listening skills, the videos indicated that watching movies with subtitles is a the wrong way because our brain chooses to receive information from the subtitles but not the actors’ conversations. Also, movies are too long so we waste a lot of time. Therefore, a good way to improve listening skills is to listen to podcasts because each of them is they are short and we can focus on listening only. We can listen to those dialogues when we are taking the bus or having meals.

To memorize vocabulary, there are some steps to follow. First, we determine the numbers of syllables and repeated letters. Then, we categorise the word as good, bad, or neutral. At last, we create an image. What we are trying to doing is to processing a deep memory so as to increase the ability of word recognition.

These strategies make sense to me so I would like to try them out. Do you think they work or do you have any alternative ways to improve English? Please feel free to leave a comment. Thank you!
