Evaporation; Condensation – Don’t Get All Misty-Eyed!

I decided to give a quiz of sorts on Monday of this week.  I asked the students to write the word <prejudice> on one side of the paper, and <segregation> on the other.  These are words that we have investigated in the last two weeks.  For each I wanted:

1)  the definition
2)  a word sum
3)  two other word sums showing the base with other affixes
4)  two words with related meanings

I learned much!   The vast majority of the students spelled both words correctly, but the vast majority did not write an accurate word sum for that spelling.  For some of my students the tendency is to divide words by syllables rather than bases and affixes.  This makes for some random word sums as their hypothesis!  Even though they have knowledge about certain prefixes and suffixes, they aren’t applying that yet on an automatic basis.  I’m confident that as the investigations continue, and they talk about why they are making the choices they are making, that this will all come together.

Today we split into four groups.  Two groups investigated <evaporation> ,and two groups investigated <condensation>.  Rather quickly, both groups looking at <evaporation> found the base element to be <vapor>.  We all found out that <e> is from the prefix <ex> which means out.  That really helped with picturing evaporation!  Students used their hands to describe the vapor moving in an outwards direction.

 

 

The suffixes <ise> and <ize> in the matrix for the base <vapor> reminded us of the books we read by Roald Dahl earlier in the year.  As we read we collected spellings that were slightly different than what we were used to.  We remembered the word <realise>, which we knew was a British English spelling rather than what we are used to – American English spelling.

The two groups investigating the word <condensation> approached it quite differently.  The first group began with a pretty accurate word sum hypothesis.  Then they looked up <condensation> and <dense> to find out more.  With prompting they added the meaning of the prefix to their understanding of the base.

The second group was trying all sorts of random letter combinations as part of their word sum hypotheses.  At first it didn’t seem as if they had a plan, meaning a logical order for how to proceed with their investigation.  When I asked if they had looked on their list of proven prefixes to see if anything matched what they were seeing in the word, things began to click.

Curious Minds … apartheid and discrimination

As we continue our study of the Civil Rights Movement, interesting words keep popping up. So far we have looked at prejudice, segregation, and integration. During the research into those words, the words ‘apartheid’ and ‘discrimination’ surfaced. Intrigued, we began with the word ‘apartheid’. We read some information and recognized that there were some parallels to be drawn between the situation in South Africa from the late 1940’s to the 1990’s and the situation in the U.S. prior to the 1960’s. Then we wondered how the words ‘apartheid’ and ‘discrimination’ fit in with the other words (as far as meaning) that we have collected on the topic. It was time to investigate.
Two groups of students investigated the word ‘apartheid’. Here is what they found.

Three groups of students investigated the word ‘discrimination’. It was fascinating to listen to the hypotheses the students started with, and then the reasoning they used to alter them. It’s been pointed out to me by other orthographers that what I see happening while the students investigate and recap that investigation is the really worthwhile part of all this. I believe it.

While watching the following video, I thought of what the three groups found. Tomorrow each group will be asked to consider the following:

1) One of the groups found that ‘dis’ is a prefix and means away from. Can that be proven or disproven?
2) We know that ‘in’ is a prefix. Is it also a suffix? Check on WordSearcher for other words that end with ‘in’.
3) One group believes ‘ate’ and ‘ion’ are both suffixes in this word. Another group believes ‘at’ and ‘ion’ are the suffixes. How can we prove/disprove either of these?
