Why are there always sentences on the front of vocab flashcards?

NativShark teaches Japanese with context from a situation and/or a sentence.

Japanese is a highly contextual language, which means that studying Japanese with no context often leads us learners to make incorrect assumptions about how a given piece of Japanese can be used, and even what it means.

An example

Let’s take a look at the following verb:

掛かける

This verb has 25 meanings according to Jisho.org:

to hang up (e.g. a coat, a picture on the wall); to let hang; to suspend (from); to hoist (e.g. sail); to raise (e.g. flag)
to put on (e.g. a blanket); to put on top of; to cover; to lay; to spread
to put on (glasses, etc.); to wear (a necklace, etc.)
to make (a call)
to spend (time, money); to expend; to use
to pour (liquid) onto; to sprinkle (powder or spices) onto; to splash; to throw (e.g. water) onto
to turn on (an engine, radio, etc.); to set (a dial, alarm clock, etc.); to put on (a DVD, song, etc.); to use (a device, implement, etc.)
to cause (someone inconvenience, trouble, etc.); to burden (someone); to impose
to multiply (arithmetic operation)Mathematics, Usually written using kana alone
to secure (e.g. lock)

…I’m going to spare us from the other 15. But feel free to click the link above if you’re curious to see them all.

A test

Let’s say we have a flashcard that only shows a single vocab on the front so we can focus on it in isolation.

Okay, here we go:

Front:

掛ける

Which of the 25 definitions is this one?

☠ ☠ Thinking Space ☠ ☠

☠ ☠ Thinking Space ☠ ☠

☠ ☠ Thinking Space ☠ ☠

☠ ☠ Thinking Space ☠ ☠

☠ ☠ Thinking Space ☠ ☠

☠ ☠ Thinking Space ☠ ☠

☠ ☠ Thinking Space ☠ ☠

Back:

If you guessed anything other than this specific one (number 6), would you say you were wrong?

I wouldn’t at least. But this is a really good example of why context is so invaluable when studying Japanese.

If we chose to teach per vocab word instead of per usage with context, we would end up with a list of 25 definitions and sentences on how to use them. On a single flashcard. We’d probably all be going crazy

If we did teach them all in different flashcards, we would have no way of knowing which of the 25 definitions this one was because we have no context and indicator of what it means.

That's why we don't mention on this card how you can use this word when you "hang up" your coat. We teach that elsewhere, in its own appropriate context ^^

The power of context

By having a sentence and the context of the situation on the front of the card, it helps us fully understand when and how a word can be used in a much more realistic situation that we’re more likely to encounter when using Japanese.

Even if it’s a one-word sentence we run into in real life, there’s still the context of the situation we’re in that helps us figure out what the other person is saying.

This is different from an isolated vocab flashcard, which just teaches words in a vacuum until you see the back, making half of the flashcard unhelpful and quizzing you on something that you would never experience when out using the language.

For example, if you’re eating dinner with your friend and you get 唐揚[からあ]げ, you or your friend could pick up the lemon and hold it over the 唐揚[からあ]げ and say, “かける？”

You would know that they’re referring to squeezing lemon on the 唐揚[からあ]げ, not locking up their house like definition 10 means because of the context.
