The last skill we will talk about is synthesizing. This is a combination of all three of the previous skills — taking notes, paraphrasing and summarizing. You use each one of these skills when you synthesize. Some of them you use more than others, but that’s always true.
When you synthesize, you combine information from several sources to make something new. You will probably take notes from two (or maybe even three) sources. Usually you will write a summary about one of those sources, and then add more information from the other source.
The final synthesis is not a summary, and not a paraphrase. It’s bigger than a summary, and uses too much information to be a summary. It also isn’t a paraphrase, since you’re really starting with a summary and adding to it. The information you add might be a paraphrase, since it’s written in your own words, but the final product is not.
Your final synthesis will be longer than a summary, made of a summary, but using extra stuff. So it’s different.
Here’s how you make one. Here are notes from a reading about ice cream.

Here are some more notes, this time for a lecture on ice cream.

I had vanilla ice cream for breakfast today. |
The first thing we need to do is identify the main source — which we can’t do until we know the question. So you have to take really good notes for both sources, because maybe one will be summarized, but you’ll need details from the other. Always, always, always take good notes.
Next start a summary of the main source. For this example, the question is, “Summarize the reading, adding information from the lecture.” That’s easy. We just start a summary of the reading, and add details from the lecture when they are important. Here’s a start:
Ice cream is a dessert made from milk, sugar and a flavor.
That’s the start of a summary. Now we add details from the lecture.
Ice cream is a dessert made from milk, sugar and a flavor. The most popular flavor is chocolate, which is made from cocoa beans.
That’s part of our synthesis. See how we used details from one source, to explain the other? Let’s keep going.
Ice cream is a dessert made from milk, sugar and a flavor. The most popular flavor is chocolate, which is made from cocoa beans. Vanilla is not as popular as chocolate, but is also made from a bean. Strawberry is made from fruit.
Almost done. There’s only one thing that’s important, and it’s from the main source.
Ice cream is a dessert made from milk, sugar and a flavor. The most popular flavor is chocolate, which is made from cocoa beans. Vanilla is not as popular as chocolate, but is also made from a bean. Strawberry is made from fruit. Ice cream was invented in 1731 by a Finn called “Icey.”
And that’s all there is to it. Your answer is not a summary. It’s not a paraphrase, and it’s a lot more than notes. It’s all of those things combined to make something new.
Some final tips:
- Make sure you identify the main source. As soon as you read (or hear) the question, you will know which one is the most important. Remember to focus on that one.
- Make sure you understand the relationship. Some questions will ask you to compare two sources. Some will just want the information added. Some will ask you to “cast doubt” on a source — for that, you use information from one source to show how the other source is wrong. Read the question carefully and make sure you answer it properly.
- Take really good notes on both sources. Remember: You don’t know which one is important until you hear the question. So take lots of notes on both.
Try some of the practice exercises in the book. There are no time limits and you can try them in any order.
Here’s a snapshot of the whiteboard from Sunday, so you can remember what we talked about.

Good luck!
