There are several methods to remember vocabulary, with varying effectiveness based on the learner's learning style. Here we will detail a few methods to remember words in your target language.
The SRS, or spaced repetition software, method is widely debated. Some find it completely useless, others swear by it. The only way to know if it will work for you is to try. The theory behind space repetition is that the software will bring back a word just as you are about to forget it, and thus reinforce it in your brain. Most SRS programs have a system of rating how well the word was remembered and adjusts the interval for it accordingly. SRS programs are often considered better than flashcards because they focus on learning only rather than drilling into memory.
Some people find learning easier when accompanied by movement. This is part of the theory of the [shadowing] method; that the brain works better while the body is active. There are two main types of this: "general kinesthesis" and "related kinesthesis".
"General kinesthesis" simply means that the body is moving while the student is attempting to learn. This can be accomplished by almost any activity, such as walking, running, riding a bike, or jumping on a pogo stick (not suggested multitasking if one enjoys keeping their blood inside their body). This would probably be most effective with audio as input, which is easier to use when moving than the printed word. However, with certain equipment (such as an exercise bike), print is fine.
"Related kinesthesis" means that the action that the student does is related to the meaning of the word. For example, if one were learning the Spanish word "manejar" (to drive), they may imitate the motions of driving, or actually do so, if they were in a vehicle at the time.
Mnemonics can also help with vocabulary acquisition.
