Here are some language learning tips for left-brain learners:
Take advantage of a formal language school program if possible. Your left-brain skills will help you do well and enjoy it.
Do not fear designing and carrying out a personal language learning program. Your left-brain skills are a strength for this.
Use your analytical skills to learn the language.
Break words into their parts and try to identify the rules for putting them together.
Look for similar rules and patterns in the way words go together to form sentences and other language units.
Do not be surprised by your frustration at the chaos, ambiguity, and uncontrolled nature of natural language situations. It will eventually make more sense.
Be careful about expecting too much of yourself. Language learning takes time and does not always yield to an organized and logical approach.
Use your analytical and organizational skills to figure out the important factors of the communication situation. This will help you learn how to respond appropriately.
Be careful you do not shut down and stop trying to understand when you cannot figure out all the parts. At those times, make a conscious effort to relax, to let the language flow over you, and to be content with getting the main ideas.
Take advantage of techniques such as grammatical analysis, drill activities, puzzles, and hypothesis testing.
