Why We're Opposed to the Star-Section System



The star-section (fast-track section) system or is currently a trending class stratification and labeling system that sweeps throughout secondary education schools. While I understand much of its rationale which I will elaborate, I humbly disagree with the educational philosophy behind this system because of important points which I will discuss in this editorial. This topic has been in my mind for four years. It is also possible that my reading of the manga Ansatsu Kyoushitsu, under the tutelage of my beloved Koro-sensei, allowed these words to flow.

The star-section system is utilitarianistic in nature. Students who have very high GWA are selected to become classmates in the section known as the star-section, under an accelerated, more challenging pace of lessons. This is, to a degree, worthwhile especially for these students whose grades do really match their intelligence, because they can advance their knowledge and skills even further by facing greater academic challenges and participating in academic contests. This is also beneficial for the school, because the school can easily select their students to represent the school. On the surface, the students in this section are more or less assured of a wonderful future. The school sends best of their teachers to this section in order to teach the “best of the best”. Students are promoted to become more and more conscientious if they want to stay in that section; consequently, they become more grade-conscious. To the so-called primary stakeholders of this system – the school, the teachers and the star-section students and their parents (who may sometimes exert greater influence under the meritocratic-like system of the school), this is a good thing to do on the surface. However, this polarization creates flaws, both to those who merit from this system and the “ordinary” students.

Underneath this lies a fatal assumption. Can we accept that the school intends to maximize the abilities of the “bright” students who “show promise for a great future”, while inadvertently believing that the other students “have limited futures” and therefore must be subject to “normal education”? This is intentional labeling, and that’s a separate point that I will discuss later. Ultimately, star-section system unconsciously features a polarized self-fulfilling prophecy, while those “other” students are doomed to a future with limits. High-GWA students are met with plenty of opportunities that are not open to others. Moreover, it is not given that the students of the “other” sections are unwilling to undertake great challenges. Therefore, it's not a question of willingness or capability. At this point, it is at its root, a means to discriminate against students who do not perform to standards that were initially tailored to a singular type of student or the so-called “ideal student”.

In the first place, the lone-standing GWA is not a reliable indication of an intelligent mind, much less a student who deserves better education or teaching methods simply because he or she “shows promise for a good future”. On the contrary, to a very limited extent, grades do define students commensurate to their effort in studying. There are plenty of other parameters that one should pay attention. Many of the world’s greatest inventors, innovators and revolutionaries are those who never got a high GWA. However, because education treatment among students is polarized by this GWA-determined star-sectioning system, we can also say that those who simply didn’t reach the cutoff are deprived or deviated from a supposedly better standards of education. It is highly probably that these students who are not in the star-section are deprived of teaching methods that would allow them to learn and benefit as much as those in the star-section.

Along the line of consequential thinking, we know that secondary schools offer a limited “diversity” of students. The original paradigm of students randomly distributed among all sections maximizes the limited diversity. However, stratifying, polarizing and labeling students into one exclusive section worsens this limitation. High-GWA students are limited to interacting with fellow grade-conscious or “intelligent” students, and there is a lack of development of communication skills to those who are not as “intelligent” as them. People grow with the variety of personalities from their peers. Being exposed to the different types, personality or attitudes of people around them helps them grow. How can the failing student learn to strive without the high achiever to set the standard? It is highly improbable for the student who fails to see the “high” lives of the overachievers and therefore miraculously generates a drive for good grades. How can you make the arrogant genius communicate with the students who need extra effort to pass their subjects? How can a teacher discipline or teach what is right to a group of arrogant geniuses who are obviously wrong about something when their collective pride is so high up in the heavens?

Just as it was mentioned above, the star-section system categorizes students according to their GWA. Categorizing leads to labeling. Labeling tolerates deviance and ultimately bullying. Not only is communication amongst students limited, the culture of bullying is worsened – not just to fellow students but even to teachers! Teacher-bullying can be a consequence of the pride of the high-GWA students. The high-GWA students can be led into having an inflated sense of ego, thinking that they are better than the others. The high-GWA students can collectively bully the low-GWA students (as seen in many instances not only in the manga Ansatsu Kyoushitsu), and the low-GWA students can smart-shame or define an imaginary, “anti-nerd” exclusivity against the high-GWA students.

Ultimately, education is still best done under the original system, and the school should promulgate the right mindset to education especially to its students – diversity, intellectual humility and communication, simply because life is more than just GWA. In life, we get to meet many people who can never be in the same level as us. In life, teachers are more than just secretaries or “grade accountants”; they teach, introduce ideas and shape the future through their students! Consequently, the education system should be geared towards those rationales (including the need of higher salary for teachers, and the need of free education)!

The following part is not entirely relevant to the main article, but can probably explain why I wrote this article.

Koro-sensei made me think about educational philosophies.

I may not be able to address the errors in educational philosophies of categorizing students in tertiary education institutions, but they need to be checked. There are questions that are yet to be answered and have their answers justified, such as “Why is there a tinge of prejudice when we hear that somebody studied or is currently studying in prestigious schools such as Ivy League schools, MIT, Harvard, UP, Ateneo, etc.?”

Personally, I’ve been deprived of “advanced math education” in high school because I simply “wasn’t qualified”. The ones who got in didn’t even take entrance exams, but it’s ultimately okay since they joined several math contests unlike me. I have nothing against them. Meanwhile, I did take an entrance exam, and I got a score less than 50%. In other words, I failed. However, I was so sure that my answers were correct, and so I even discussed and justified my solutions with my math teacher who agreed with my solutions. In the end, I still didn’t get in, and so therefore I had to forge my own path by joining Mathematics Trainer’s Guild (MTG) and winning contests by myself. Honestly speaking, it isn’t right to say that I was representing my school when I joined those contests. I only represent Kumon, MTG, my parents, myself and my beloved teachers who taught me math.

Viruses ARE Living

Viruses ARE living things.

"After analysing the folds in 5,080 organisms and 3,460 viruses, the researchers found that viruses and modern cells share 442 protein folds, and only 66 are virus-specific. But those 66 are unlike anything seen in cells, which contradicts the hypothesis that viruses simply took all their genetic materials from cells.

This information allowed them to build a rough tree of life, which showed that viruses share a common ancestor with modern cells, but are more ancient.

"Viruses originated from multiple ancient cells ... and co-existed with the ancestors of modern cells," the researchers write in Science Advances."

TEDxUPM - 10/2015

Michael Green. April Cuenca. Dr. Raquel Fortun. Jerrold Tarog. Ebe Dancel.

I attended a TEDxUPM talk. With the more diversified topics and disciplines yet presenting a unified theme, this outside-the-classroom experience is irreplaceable. The speakers (including the TED videos presented) were as follows:

1. Video: What the Social Progress Index can reveal about your country by Michael Green: It IS POSSIBLE (contrary to what pessimists say) for the world to be a better place when, according to Michael Green, all countries strive for economic growth and at the same time eliminate poverty. This can increase our Social Progress Index from a mediocre score so somewhere around 61+. However, in order to reach UN's Global Goal of 75, we have to do things differently - not through the conventional business transaction.

2. CEO and Founder of FlipTrip.PH - April Cuenca: Go from your point A (your status quo) to point B (your destination). We should be willing to find places in the Philippines to travel. Tourism is something very important to the livelihood as well as social development of the local communities.

3. First Woman Forensic Pathologist in the Philippines - Dr. Raquel Fortun: The state of Philippine Trial courts ranges from the well-decorated Makati Trial Court (with genuine wooden material) to the lackluster (with broken chairs) ones. As a forensic pathologist, she is qualified by the trial judge as an expert witness (contrast to the ordinary and professional witness), who is reliable in terms of hypothetical crime scenarios. She has taken the relatively recent Laude's case.

4. Director of Heneral Luna - Jerrold Tarog: Heneral Luna, apparently, is his ninth film. He was originally a music major who without much difficulty shifted to film making. Why is this so? "Music is film and film is music to me." (Tarog, 2015) There is color (timbre), story structure (such as three-act and sonata structures), fugue, motifs (and visual motifs) and beauty in editing. Movies have a beautiful way of amplifying emotions along with music using the beat rhythm (composed of upbeats and downbeats), such as adding new instruments into the "music scene" in every downbeat (1 in 1, 2, 3, 4).

5. Gerson Abesamis, co-founder of Habi Education Lab: The current state of the country, especially in education is having a deficit-based mindset, and this is very dangerous because it does not encourage good learning. We need to shift from deficit-based mindset to asset-based mindset - which is using whatever we can do - all of them to creatively teach students (such as gamification). Another universal lesson I learned is that "Good intentions alone can be dangerous and can cloud your judgment. You have to think critically."

6. Video: Wapnick, founder of the website Puttylike: Our society is so wrong in making us believe that we have one, ultimate destiny - something we should fulfill in our life by the question "What do you want to be when you grow up?" This is a question that's casually asked to a five-year old and currently an all-night worrying thought for those who are in their career. She asserts that we people who are interested in many, many, different fields SHOULD NOT restrict, narrow ourselves into one! We are MULTIPOTENTIALITES. We have three superpowers: Idea Synthesis, Rapid Learning and Adaptability. There are many well-known, world-changing people who are such (a doctor and violinist, a doctor and programmer, etc.)

7. Lead Guitarist and Vocalist of OPM Band Sugarfree - Ebe Dancel: Music. Music. Music. Music. Music. Music. I cannot describe how much I am touched by his singing.
Fanciful as it may sound, I got a TEDxUPM shirt, lanyard and even the autograph signatures (and photos) with Dr. Fortun and Director Tarog. I am thankful to the organizers for organizing such as awesome event. I look forward to attend more TED talks.






Cancer-driving Enzyme

Scientists finally figure out the structure of a key cancer-driving enzyme

A Immunological Cure for Cancer?

"Researchers in the US have found an antibody that turns cancerous leukaemia cells into natural killer cells - a type of white blood cell that's able to seek out and destroy tumour cells in the body. If it works in humans, it would not only reduce the number of cancer cells in a patient, but could get rid of them altogether.

So far trials in the lab have shown that the converted human leukaemia cells were able to wipe out nearly 15 percent of the cancerous leukaemia cells in just 24 hours.
But instead they stumbled across a rare human antibody that has even more potential: it can actually turn leukaemia cells into cancer killers.

The antibody in question binds to a receptor called TPO - or thrombopoietin - which is found on most acute myeloid leukaemia cells. When the researchers first exposed the leukaemia cells to the antibody, they watched as it turned many of them into harmless immune cells known as dendritic cells."

Fusion of Chinese Words for New Meaning

I attempted to fuse Chinese words into one word for a fuller meaning. The words above are the original words, while the words below are the "synthesized" words. The intended meanings are as follows, from leftmost to rightmost:
1. 笨 means "stupid". I added two 本 (which means books). This word means that you can be extremely stupid even though you know a lot of content from the books.
2. 傻 also means "stupid". I added a 牛 (which means cow). I wrote this word thinking of "baka baka" in Japanese.
3. 痛 means "pain". I added 愛 (which means love). Enough said.
4. 愛 means "love". I added 痛 (which means pain). Enough said.

Erythropoiesis - in a new perspective?

Does this mean that textbooks need to be corrected?

"In a classical view of hematopoiesis, the various blood cell lineages arise via a hierarchical scheme starting with multipotent stem cells that become increasingly restricted in their differentiation potential through oligopotent and then unipotent progenitors. We developed a cell-sorting scheme to resolve myeloid (My), erythroid (Er), and megakaryocytic (Mk) fates from single CD34+ cells and then mapped the progenitor hierarchy across human development. Fetal liver contained large numbers of distinct oligopotent progenitors with intermingled My, Er, and Mk fates. However, few oligopotent progenitor intermediates were present in the adult bone marrow. Instead only two progenitor classes predominate, multipotent and unipotent, with Er-Mk lineages emerging from multipotent cells. The developmental shift to an adult “two-tier” hierarchy challenges current dogma and provides a revised framework to understand normal and disease states of human hematopoiesis." Distinct routes of lineage development reshape the human blood hierarchy across ontogeny

The Library of Babel

According to the video, there's this website called The Library of Babel. (https://libraryofbabel.info/), wherein if you enter any up to 3200-character combination of text (which is composed of the alphabet in lowercase, comma, space and period), the exact permutation will definitely be found.

Technically, this "blurs the line between invention and discovery" because everything is already predetermined. In fact, this very post (excluding other excluded characters) can be found there. How is this possible?

This is not something like "the computer detects what you enter in the search box and then generates something from it". No. The computer uses seed numbers from base-10 and converts them into base-29 and generates every possible combination based on it. Messages For The Future

Artikulo Uno: Heneral Luna

"Early in June, Luna received a message from Aguinaldo asking him to go to Cabanatuan. Luna left his command in Bayambang, Pangasinan and proceeded to Aguinaldo's headquarters, arriving there on June 5. He was angry to see that one of the sentries was a member of the Kawit Company which he had asked Aguinaldo to disband for military insubordination, and on going up to Aguinaldo's office, angrier still to find that Aguinaldo had gone out of town to inspect troops.

While he was arguing heatedly with Buencamino, he heard a shot and rushing down to investigate the disturbance was met by members of the Kawit Company who then stabbed him with bolos and fired at him until he died. He received about forty wounds. The next day, he was buried with full military honors on Aguinaldo's orders, but the Kawit company assassins were neither questioned nor punished." - from The Philippines, a Past Revisited by Renato Constantino, p. 223

HENERAL LUNA

Thoughts of UP Manila Chorale's Talindaw

1. I learned that "Sieg" in German means "Victory" in English. Indeed "Sieg Jesus" means Christ is our Victory.

2. I was able to completely visualize the suffering of Christ through the vocal glissandos in the song "Eli! Eli!" The image was something like "Christ inundated with exhaustion and suffering". The immense depth of every repetition of "Eli! Eli!" still reverberates through my mind.

3. Until now, I'm still trying to completely contemplate and get a grasp of "De Profundis!". Profundity means "depth", and the lyrics are lifted from Psalm 130. In their song there were continuous, constant, low-note repetitions of "De Profundis!" while the other lyrics were done in a chaotic-domino-effect fashion, along with several other arrangements which I most likely didn't notice. Indeed it is something which I could call "several lamellated layers of depth-filled music".
 

4. Since two songs were dedicated to Torrevieja, I had to search it up. Torrevieja means "Old Tower" and currently it is a municipality in Spain.
 

5. Their rendition of the "Bituin Walang Ningning" is otherworldly.
 

6. I can only remain in utter reverie in their rendition of "Rolling in the Deep". Despite the choreography, stomping, rhythm variations and dramatic sforzandos, they were able to maintain such an immaculate synchronicity.
 

7. Contrary to the programme sheet, they performed additional songs, "Overture" and "Circle of Life" (from Lion King). Overture was really awesome, with its perfect metronome.
 

8. Circle of Life, on the other hand, transcends the very definition of "vividness" and "reveries". They were not only able to maintain a perfect rhythm, but they were also able to integrate animal sounds, meticulous as they are - bird, monkey, etc. Hats off to the amazing soloists who powered up the chorus.

P.S. Maybe it would be even better without the "mic of death".

John Cage - 4'33"

Zipf Mystery

Try reading a body of text (of natural language) and count the frequency of each word. After that, try ranking them in decreasing frequency.

You will notice that that frequency of the second in rank is about half as much as the first, while the third being one-third as much as the first, and so on. (This may become more accurate with a larger sample size, i.e. more word count.) Why is this so?

This phenomenon involves something we call "Zipf's Law".

In any language, any corpus of literature and any set of natural language utterances, the frequency of occurrence of a word is inversely proportional to its rank. For example, "the" is the most commonly used word in the English language. "Be", which ranks second, occurs about half as much as "the". "To", which ranks third, occurs about one-third as much as "the".

According to this video and Wikipedia as well, this kind of distribution or pattern is found in city populations, solar flare intensities, protein sequences, immune receptors, amount of traffic internet websites get, earthquake magnitudes, number of times academic papers are cited, last names, firing patterns of neural networks, ingredients used in cookbooks, number of phone calls people receive, diameter of Moon craters, number of people die in wars, popularity of opening chess moves, even the rate at which we forget, the planets, the elements in the periodic table.

This distribution followed what the video mentions as "Pareto Principle", where 80% of the effects come from the 20% of the causes. This principle is in fact found in our society, wherein 20% of the population owns about 80% of the wealth! Another example from the video is that Microsoft noted that by fixing the top 20% of the most-reported bugs, 80% of the related errors and crashes in a given system would be eliminated. In the business world, 20% of the customers are responsible for 80% of the profits, and 80% of complaints come from 20% of customers.

According to the video, try having a pool of paper clips. Get any two paper clips and link them together. After that, return it back to the pool. Repeat the process. After some time you may notice a disproportionate paper clip chain ranking first relative to the others. This is simply because the first has more chances of being chosen or being applied an effect.

Is not this similar with "The rich get richer, and the poor get poorer." and "The popular ones become more popular." - something like a positive feedback mechanism? The video mentions "Principle of Least Action" and "Preferential Attachment" as possible "mechanisms".

If all natural processes follow Zipf's Law, then is there any hope of getting out of this natural phenomenon, most especially when such phenomenon is bad?
