Random thoughts: Knowledge is hypothesis tested

During my course, I learn about several strategies for pupils to remember vocabulary taught. One that intrigued me is the Frayer model.

In short, it's a model that also highlight examples and non-examples as well as meaning etc for a deeper understanding of a word.

I tried it for both my higher progress and lower progress pupils. I have since discard both.

For the LP, it's straightforward, they can't even understand the meaning, no point going so deep into the concept.

As for the MP, I struggle for a while. The pupils seem bored when I am explaining the model. I think to myself, maybe it's the delivery problem. So I turn it into a game whereby pupils read the table and and take away 1-2 information and get their oppositing team to fill in the right answer. It's a kind of a way of "forced" reading. Reading by itself is quite neutral for "memory", so but playing this game, they did "search reading", then retrieval process and replacing the lost information. This will be followed by a final paper and pen test on the vocab. 

After doing these for 2 chapters and my old way of just "guess the picture" game and bingo game. And looking at the performance of the vocab test, there is no difference. But my older "method" is much faster. 

I am not saying the frayer method is not good. I am saying it has not yet become "knowledge" for me and hence it yet to be useful. It will stay as theory until I can find ways to exact value out of it.

The simple act of connecting a comic to words however work better. I ask my pupils what is the difference between 辩论 and 争辩?silence.

I ask when have we seen the word 辩论?

I say Remember pikachu sitting in circle with other Pokémons deciding whether or no to continue battle in comic strip for chapter 15? Oh oh oh that! Debate! A few hands go up the air. 

Maybe we should not scoff at "simple" theory.

I told my boss my project with my department is about giving feedback. I can tell from her face although she didn't say it is why is it worth "Researching and testing". It is such a basic thing.

Well, buy low sell high also basic lei. 

I have seen so many presentations that is centered around how teachers give feedbacks. No one talk about changing the feedbacks according to circumstances and learning progress of pupils. 

We all heard about how to make money by investment legends. But I have not applied through different market conditions. So, perhaps the theory has yet become knowledge. 

However, there is nothing to scoff at. It's just our intelligence level to apply theory. There is nothing wrong with value investing, neither is there anything wrong with trading and stop loss.
