The Math IA that I had to write this year was about the Gini Coefficient. I had actually thought of this topic when studying Geography as the Gini Coefficient was mentioned in a lesson and really interested me. After doing more research, I found that there was a great deal of math involved in the Gini Coefficient. So I decided it would be a good topic to look into for my IA. The following is the introduction to my IA:
At the beginning of the year, learning calculus really came of great interest to me. Starting with limits, derivatives, and integration, I became quite interested in the expansions and applications of the topic. During my own research and studying ahead in the textbook, I came across integration and the calculation of the area under a curve, which I understood to be the opposite of differentiation, which I had already learned. The varying ways in which the area under a curve can be calculated mechanically, without the function, really interested me. Furthermore, the application of such calculations would prove to be of interest and show links between the subjects I am studying, in particular geography.
The Gini Coefficient is one area of geography in which I had studied earlier in the year. The Gini Coefficient identifies the income inequalities within a specified region, usually a country, and then calculates a coefficient between 0 and 1, to quantify the inequalities. The calculation of the area under a curve is directly linked to the calculation of Gini Coefficient.
This far in math I think that I am doing quite well. I am generally finishing all of my homework in class, but if not I finish it at home. I think that I am keeping a good balance of talking in class and actually doing my work. I am trying to limit my talking in class, but that is probably one more thing that I could improve on.
I think that in Science I am doing pretty well. For the last unit I understood all of the material, but on the test I didn’t do as well as I hoped. All I think that I could do better would be focusing more in class and not socializing as much. I understand most of the material, but I think by listening more I will understand better.
Right now in English we are doing our speeches. I knew what I wanted to do already and I finished my speech very quickly and now I am reviewing it and memorizing it. Overall right now in English I feel I am doing quite well.
In Socials I feel I am doing quite well. For our last project which was making a collage on some one important from the renaissance I received 7 of 8, 8 of 8, and 6 of 8.
These are a few of the classes I would like to comment on for the rest of the classes I am doing well too. Overall I think that this new term has been going quite well right now.
So far this year in math we have covered integers, ratios, fractions, percentages, and are partway through algebra. I think that I had a solid understanding of the first unit this year that included integers, fractions, and ratios. On the test I received a 5 -5 mark. I could solve most of the basic problems, and most of the higher level questions. I was good solving operation with fractions, I could solve division, multiplication, subtraction, and addition problems. I could also solve most integers problems with ease. I had a basic understanding of ratios as well, I found some of the ratios problems a little challenging, but I didn’t have too much trouble.
The second unit was percentages. For the basic percentages problems I was good with solving, but once it got to the higher level problems I had more challenges. I received a 5-4 mark on the test. I think that I had a generally good understanding of the percentages unit although I could improve a little more .
Finally, we are on our last unit before Christmas break, algebra. I think that I am doing well in algebra right now. I understand how to simplify expressions, and create a number trick. We have just done the number trick and I think that I have done pretty well on it.
Overall I think that I have a good understanding of all the math this year, although I can still improve.
I think for my first math test of the year I did pretty well. I got a 5 – 5 mark. this is around the average, or a bit over. I think that my strengths on this test were doing the order of operations questions. I got most of these right, even the more tough ones with more difficult problems. Another one of my strengths is doing the operations with fractions. I did quite well on this part. My weaknesses were on the harder 7 -8 level questions at the end of the test. These questions are unfamiliar questions that are much harder.
