Math Internal Assessment Reflection

Mind Map

Before I start writing my draft, I started to brainstorm about the topic of my Internal Assessment. I first started with a big topic, such as science, sports and shopping. Then I started to extend my ideas based on that topic, and linked them with possible maths of those extended topics. However, my mind map was too general and simple to narrow my thought and come up with an appropriate topic for my Internal Assessment. I started to think what I am really interested in and what I was always curious about. Then I came up with the topic ‘food’, and extended my idea with ‘fast food’. As soon as I came up with a specific topic, it got lot more easy for me to make a research question and therefore an overall clear topic for my Internal Assessment.

Criterion A: Communication

In my draft, I have clearly outlined an introduction that mentioned my aim and the reason of my investigation. Some things that I should be aware is that I should make the key words in bold and define clearly. In addition, I should be more specific with the terms that people might not know, such as franchise form of a business.

Criterion B: Mathematical presentation

For appropriate mathematical languages, I should show clear notations, and make sure that all the variables are defined. In the process of typing mathematical notations, I could use MathType and my GDC. This is an use of technology. Again, my key terms, such as average,  should be defined clearly. In addition, as I use tables to summarize the results from my experiments, I should make sure that my tables are labelled and organized appropriately that the readers can understand the information on the table.

Criterion C: Personal engagement

Personal engagement on my Internal Assessment is that my investigation is fully based on my interest and curiosity. I should think and work independently and think creatively. Considering historical and global perspectives is also very important for my personal engagement. I should consider when Korea first accepted fast food restaurants and how Korean food culture changed based on fast foods. I can expand this by connecting with fast food consumption of Koreans, organizing by histograms and statistics tables. I could further explore and research about this on the Internet.

Criterion D: Reflection

I should consider all the limitations of my experiments, such as lack of trials to conclude in general which chain has the fastest speed of service. Also my conclusion can link with the extensions of the change of Korean food culture, and how this could relate to the consumption of fast food.

Criterion E: Use of mathematics

I have only considered calculating the average of speed of service, however I should consider much more use of mathematics that commensurate with the level of the course, such as standard deviation. I need to make sure that I define clearly and label appropriate notations for this. Use of mathematics in statistics unit will be mostly used throughout my Internal Assessment.

Biology Article Reflection

1.) What does a synthetic type of DNA mean for the scientific community?

The creation of the first “semi-synthetic” micro-organism is considered to the scientific community as the first step towards creating new microbial life-forms with novel industrial or medical properties resulting from a potentially massive expansion of genetic information. The DNA of the new semi-synthetic microbe has a pair of extra base pairs, denoted by X and Y. It pair up together just like the other original base pairs (A,T,C,G) and are fully integrated into the rest of the DNA’s genetic code.

2.) How might having a fifth and sixth nucleotide base affect the future of drug delivery systems?

When the E. coli bacterium replicate the X and Y bases are fed up. If X and Y bases are lacking, the microbial cells revert back to the natural genetic code. In order to fill in the X and Y bases, synthetic chemicals called d5SICS and dNaM, that do not exist in nature, should be used. This would encourage the future drug delivery systems to create such chemicals. Such systems might be able to earn lots of money by these chemicals.

Chemistry of Life Unit Exam Reflection

Overall, I did not do quite well on the unit test of Chemistry of Life. There are some questions that I lost points by silly mistake, such as changing the order of the answer or reading the wrong thing on the graph. There are also some questions that I lost points by lack of knowledge of the concept. Question number 5 requires me to explain how the light-independent reactions of photosynthesis rely on light-dependent reactions, and for this question I only got 3 out 8 marks. This is because I did not have full understanding of the concept of photosynthesis. I tried to write what I know as much, however there was a limitation of my answer. In addition, question number 10 asks to describe the significance of water to living organisms, and I only got 3 out of 6 marks. As the full score is 6, I thought it was 2 marks per 1 type of significance. So I wrote down 3 significances of water, which I thought will make 6 marks in total. However, I realized that there are other more significances that could be mentioned, and therefore I only gained half point in total. Moreover, for the multiple choice questions, I realized I did some silly mistakes again, and also had lack of knowledge. After going over with my test, I realized that I should be more prepared for the test so that I could answer fully all the questions. Specifically, I should more review the concepts of water and photosynthesis and re-assess on these.  Also I should pay specific attention to the mark scheme and make sure that I do not make any silly mistakes in the future.

Biology Unit Reflection (Chemistry of Life)

For few months, we’ve went through Chemistry of Life unit. We went through lots of concepts: Water, Macromolecules, DNA & RNA, Transcription/Translation, Enzymes, Respiration, and Photosynthesis. Throughout these concepts, I found Transcription/Translation and Respiration most challenging and hard to understand. Understanding and visualizing how these processes work inside our body and plants was challenging. Especially I have not much confidence in chemistry, so I had a hard time memorizing chemistry vocabularies and equations.

Whenever I had trouble studying this unit, especially Transcription/Translation and Respiration part, I mainly used the Internet and the review guide. I searched for accurate diagrams and descriptions on the Internet and read carefully through the review guide. The review guide was really helpful as the things I need to know were well organized. In addition, I got a lot of help from my classmates. Whenever I had a question, I asked to my classmates and they were able to solve my question and help me with whatever I didn’t understand. Unlike the descriptions from the Internet or the review guide, descriptions from my peers were much easier to understand and effective.

Studying through this unit, I realized that I am relatively weak at visualizing biological processes that occur inside our bodies or plants. In order to fully understand the concept, I need to visualize it in my head or on the paper, however I lacked this ability and had a hard time understanding it. I feel I should more practice interpreting descriptions into diagrams in the future.

Article Reflection

A. Initial Thoughts:  Agree/Disagree? Why? List various points from both perspectives with specific reasons to back up your claim.

B.  IF you forget the language of mathematics and how to apply specific formulas, what does the article suggest happens to your knowledge?

C.  Answer: “When Will I Ever Use This Again in My Life?” Do you study math just to learn mathematics?  How does math class expand your horizons?  Why would this be important?  What does this mean to you personally and how would it affect your life?


I personally agree in some extent with this article. I agree that hard work is essential to improve my math skills, or perhaps in every other subjects. I also usually thought that I’m just not a math person, and was not really confident with math. However  I work hard, I get to understand the topic much more easily and get to have more interest on the subject. This eventually led me to gain more confidence and higher scores. However, I do not fully agree with the fact that hard work is always positive. The writer of the article considers Japanese, Korean and Chinese education effective, but as a Korean, I don’t really agree with this. It is true that Koreans study hard, but perhaps way too hard. They are rather ‘forced’ to work hard by their parents and teachers. Almost every high school students in Korea stay at school until 10pm, doing extra study. Otherwise, they go to private academies and take classes until late at night. Even though they come back home they still need to study and sleep only about 3 to 4 hours in average. They consider studying at school is not enough. Of course, this leads them to get higher grades, but the stress they gain is much more significant. As a Korean, I get a great amount of stress, and so do my Korean friends. We have no other extra time to enjoy any hobbies or sports. We are just forced to work tremendous amount of time. This kind of education could be seen positively as hard work, but as myself being one of those students, this education is negatively considered. There are many students who even think about suicide due to the stress they gain from studying. This is really a serious problem.

As we learn maths, we go through numerous amount of equations and mathematical symbols. Students get freaked out by seeing those equations and symbols, defining themselves as not a math person and just don’t even bother trying to solve the question. However, it is natural to not know an equation or a symbol. There are lots of various math equations, and it is impossible to know them all right away. Even a math professor has to think about it for a while when they see an equation. I feel that math is based on my mental attitude, not the genetic ability. If you set your mind that you are not a math person at all in the first place, it is totally impossible to improve maths skills, despite how much you put effort to. On the other hand, if you set your mind that your math skills are based on how you do, you get to work hard and feel much more confident than those who fail to think this way.

When will I ever use this again in my life? It would be a lie if I say I had never asked this question. I usually considered myself as not a math person, and had really small amount of confidence. This made me to be more afraid of math and avoid anything related with math. However as I continuously study math and reflect myself by reading this article, I start to get the idea of the relationship between mathematics and critical thinking. As I interpret and solve math questions, I get to think critically and expand my thoughts. Of course, I won’t be using all the math equations in my daily life of future, but I am sure this ability to think will help me in the future, despite what field I work in.

Biology Enzyme Reaction Rate Reflection

For several weeks before the CNY break, we covered the enzyme section. We learned what exactly enzyme is, and how it works with the substrate. Moreover, we learned the effects of temperature, pH and substrate concentration on enzyme activity. To learn this, we did a simple experiment in class using computer. We used a system that shows how enzyme activates when the temperature,pH or substrate concentration is changed. This activity really helped my studying of this section. It clearly showed how enzymes work in particular situations. Also, by organizing the results in tables and graphs, I was able to fully understand the effects. In addition, I  learned this section by Click4Biology. Click4Biology has every information I need to know precisely and is organized very well.

I personally like how we learn in class- how we learn individually and ask questions to Mr.McElroy whenever we need help. I think activities like the experiment of enzyme activity are really helpful for my learning.

Biology Semester 1 Reflection

In semester 1, I’ve learned Cells, Chemistry of life and Genetics. In Cells, I learned the differences between eukaryotic and prokaryotic cells and cell division. In Chemistry of life I learned chemical elements and about DNA. In Genetics I learned about DNA mutations. I think I learned everything that I want to learn. I’ve wanted to learn more about DNA as I haven’t had a chance to learn further about DNA, but fortunately I got to learn in semester 1. Among the things I’ve learned in semester 1, DNA mutations part was most interesting to me. It was interesting to learn about how the sequence of the DNA strand changes as mutation occurs.

Throughout the semester, I best learned by summarizing the things I’ve learned in notes. I used the site Click4Biology for taking notes. Using this site was very helpful. It organized everything clearly what I need to know. In addition, as I write notes on my notebook, I got to understand better and memorize the things I wrote.

In class we’ve done several group activities as well as individual activities. I personally prefer group activities to individual activities as group activities are more helpful. When I have something that I don’t understand, I could ask to my group members and get help from them. In addition, I get to work relatively harder than when it is in individual, because it makes me feel that if I don’t do well my group members will be affected and get a bad result.

Chinese Semester 1 Reflection

Clear & Effective communication- oral

P. I didn’t quite achieved to share ideas and communicate fluently with my classmates

Appropriate language usage

E. I achieved to make appropriate sentences using the words in dictation.

Language and idea analysis

P. When I analyze reading passages, I have lots of words I don’t recognize and I feel I need to practice more in solving questions based on reading passages. I had quite a hard time analyzing and understanding what each paragraph was about. I just had the rough idea of the passage by guessing from the words I know.

Idea organization- written assignment, paper 2, IO

P. I organized my ideas well in order to write my Written Assignment, however this process took quite a long time.

Written and listening analysis- paper 1, listening

P. In class we watched some movies and I had quite a hard time understanding as my listening skill wasn’t excellent. I am confident in listening something short and simple, but not in listening long and complicated things.

Math Reflection 2 (Semester 1)

In semester 1 I’ve taken 4 Individual Unit Assessment in total, and my scores average percentage was about 92%. However, on my Final Reassessment Opportunity I got a percentage of about 70%. My score dropped significantly. Because the Final Reassessment Opportunity requires me to be assessed on 4 whole units all together, I felt less confident than taking the Individual Unit Assessment. I forgot some parts in the previous units, which I was very confident before, and even though I reviewed before the test, I wasn’t able to solve the problems. In addition, the problems that I had trouble were only about 2 questions, but those 2 questions’ points were very high, so I had to lose huge points by just few questions. That had a huge impact on my whole score. From semester 1 final reassessment, I learned that I should review past units more frequently so that I don’t lose focus and forget previous things I’ve learned.

My goal for semester 1 was to manage time well. I planned to do the practice questions on the day I’ve took class so that I don’t forget the things I’ve learned that day. I was successful in achieving this goal and this really helped me when I took the individual unit assessment. As the individual unit assessment was about the things I’ve learned recently, it was able to take the test quite confidently. However as I sum up all the things that I’ve learned in semester 1, I got to be confused and forgot lots of things.

My new goal for semester 2 is to maintain my scores from individual unit assessment and the scores of the final reassessment that I will take in semester 2. In order to achieve this, I should consistently review the things I’ve learned. If I did the odd numbers of the practice questions in the individual unit, I should solve the even numbers the night before the final reassessment. In addition, I should make a clear note that summarizes all the things I’ve learned in the past and review this whenever I have spare time, and especially the day before the final reassessment. This way, I would not forget what I’ve learned. As IB course is a 2 year course, I should practice to review the things I’ve learned in the past and make sure I understood it all.

English essay reflection

So far, I have completed the 2nd draft of the essay on the topic of “Social Networks Online are inhibiting students’ academic success, which is very important for their future.” As I went through the comments that Ms. Cho wrote on my essay, I realized that I didn’t provide sufficient evidence to my ideas and didn’t challenge my thoughts enough. I just stated a quote from someone, for example a student who uses Facebook, and didn’t explain enough why this quote supports my argument. I realized that just because one student thought that way doesn’t mean that every student thought the same way. Instead I could have used statistics that show the exact ratio of students who thought in a particular way. In addition, in the essay I have made some simple grammar mistakes, especially matching the singular and plural nouns. I frequently mixed singular and plural nouns together, which is grammatically incorrect. In the future I should be aware not to make the same mistakes.
