Blogging on Blogging

Today was a good class but I'm even more impressed with what's happening outside of class! I'm really happy about the number of people who took advantage of their spare during period 2 today to get help with homework questions that were troubling them. The best thing I saw during that time was students getting together in small groups, helping each other out and learning from each other. One of the stops I pointed out on the Critical Path to Success was forming a study group. Maybe, for some of you, period 2 is the time and place to do that. What do you think?

We were talking about exactly what sort of post you're supposed to make to get that mark on your test. The kind of post I'd like you to make should have one or more of these characteristics:

  • A reflection on a particular class (like the first paragraph above).

  • A reflective comment on your progress in the course.

  • A comment on something that you've learned that you thought was "cool".

  • A comment about something that you found very hard to understand but now you get it! Describe what sparked that "moment of clarity" and what it felt like.

  • Have you come across something we discussed in class out there in the "real world" or another class? Describe the connection you made.

  • Respond to a Blogging Prompt I posted. (see below)


Your posts do not have to be long. I'm far more interested in the quality of what you write rather than the quantity.

Blogging Prompt
To help us along our blogging journey I've decided that I will also occasionally post a Blogging Prompt. It will be easy to find because I'll always put it under a heading like the one above this paragraph. Feel free to create your own Blogging Prompt for the rest of us if you like. If it's a really good one (i.e. has rich possibilities for blogging) we'll count it as your post. ;-) Here's my first one:

We've learned how to measure angles using both radians and degrees. Blog a brief paragraph identifing ways in which these two types of measurement are similar. Blog a second paragraph outlining the ways in which they are different.


This sort of compare and contrast exercise can be made easier to do using Venn Diagrams. Draw two large overlapping circles. List the similarities in the overlapping section and the differences in the appropriate non-overlapping sections. If you like, you can use this web tool to do it online. If you do blog about this prompt and want to post your diagram we'll talk about how to post pictures sometime in class. ;-)

Happy Blogging!

When we officially had our first class we started talking about why there are 360 degrees in a circle. We also found a new way to write a measurment of an angle, in a circle, with radians. Radians and degrees both correspond to the measurment of an angle from the center of a circle.

Radians is a new term, but we know that a circle is 2pi and half a circle (i.e. 180 degrees) is pi. Radians use proportions and pi. Degrees are a little harder to explain, because the measurement of an angle in a circle is a fraction of the 360 degrees of a circle. There is more that i think that can be added to this compare and cotrast, but im fresh out. Anyone have any other ideas?

Well...I can say that radians and degrees are both use as the unit to measure an angle.

The difference that I can say is that degrees of an angle is the measurement of the arc, divided by the edge of the circle,( sorry guys, I can't find the write word) and then multiplied by 360.While the radians of an angle is the measurement of the arc cut out by the angle, divided by the circle's radius.As of now that's all I can say...

I don't even know if I'm blogging on blogging blog.. But I hope this is the place. Pre cal is going good so far and I hope that it won't get any tougher which is a lie but it's not a crime to dream. I learned a lot of things from Mr. K that I didn't know before about math. Like why we do the things we do and why things the way they are in math. Before his class, I didn't really care or pay attention to why we do things the way we do in math. but now it all fits like a complete puzzle and it's pretty cool to come to a realization. I still hate math though.

I remember the first day this unit started wow I was confused, pi/4 and all these weird and complicated fractional thingys that replace degrees. And the thing that tops it off is that you had to memorize all those values! As the course progressed I started to get a feel for it and everything made sense. I think the part that made things click was not because I learned what to use to solve problems, it was that I knew why it was possible and why things acted the way they did. Basically discovering it from how the first mathamaticians did. So far most things that we learned, I understand. But when we get questions that are kind of different or real life related I get stumped. Another thing that's itching my brain is cot, csc and sec. I know how to get the values but, what are they used for? what's their purpose? are the questions. Well what I really liked so far was the group work, it really helps things click, hearing different opinions and such. I don't know I just like it.
