4 Major Advantages of Japanese Education System

One of the best thing of studying M.Ed. is that you will learn Comparative Education. That is because you will learn and compare the education systems of countries around the world.

Interesting examples are the South African and Papuan colourful (but messy) education, Dutch sex education, American carefree schools, and our own vernacular primary schools.

And of course, the much admired Japanese education system.

To be fair, I would like to share with you both the advantages & disadvantages of Japanese education culture.

We start with the 4 major advantages first:

1. It's all about the effort you put...

2. Learning is more than just the books...

3. Instill cooperation, not competition...

4. Sense of class togetherness...

Compare with our own education culture in Malaysia that made us so different from the Japanese by the general assumptions below:

1) Most of us think that we are 'born clever' instead on focusing on hard work. 
2) We learn for the sake of exam. Hence, we learnt passively from the books.
3) Our schools use ranking system to instill competition. 
4) We compete with each other to get 'first prize' in schools.
5) We prefer to 'success alone' (berjaya sorang-sorang) instead of teaching our friends
6) We prefer to tease (ejek) our friends instead of correcting them in a constructive manner.
7) We have our own minigroup (klik dalam kelas) instead of befriending all classmates. 

In the next post, we shall learn the disadvantages of Japanese education...

Soalan KBAT/HOTS - Food Intake by Teenagers

Q: Diagram above shows a pair of teenage siblings going out for lunch. 

a. Describe 2 nutrients required by both adolescents. Provide your answers with suitable reasons & 2 food examples for each nutrient.

b. Describe 3 nutrients required more by the male adolescent. Provide your answers with suitable reasons & 2 food examples for each nutrient.

c. Describe 3 nutrients required more by the female adolescent. Provide your answers with suitable reasons & 2 food examples for each nutrient.

Answers Outline:

a. Since teenagers are having rapid (exponential) growth due to puberty, both of them require more carbohydrate & proteins.

b. Teenage boy is generally more active than the girls. So, he requires more nutrients involve with body metabolism, bones, & muscles.

c. Teenage girls are generally more aware of their appearance such as acne formation. Also, they have to deal with 'red light'. So, she requires more nutrients involved with skin, menstrual cycle & red blood cells.

I used the table form is used due to its systematic outline. But you can write in essay form if you wish. Just provide 3 paragraphs (for each answer).

Clarifying the Terms Synapsis & Bivalent

In Meiosis 1, one of the confusing terms would be these two. Here is the simple diagram to clarify them all:

Synapsis is the process of pairing the homologous chromosomes (same chromosomes, different sources). Memorizing tips: Synapsis = Searching for each other

Bivalent (or tetrad) is the pair of homologous chromosomes. Memorizing tips: Bivalent = Bersama Selamanya / Best couple ever

Now you know :-)


Soalan KBAT/HOTS - Flight or Fight Responses

Today we discuss the Fight-or-Flight question & answer outline:

Q: A person encounters a potentially dangerous wild animal in the forest. Describe the changes occurring in the person's body that trigger the Fight-or-Flight responses.

This question is pretty wide in scope. So, we need to include the stimulus-response outline, as shown below:

Here is a cool note to memorize all 6 (or 7) responses. Good luck! :-)

Print this & stick it to your study wall.

Mother's Day Special : Full Notes Motor Neurone

From the previous post, we know that then function of motor neurone (efferent neurone) is to transmist impulse from CNS to effectors. Now, we shall go detail about this nerve cell. Here are your two things you should know:

1) You should know the labels...

Yup, together with the direction of impulse (shown with red breaking arrow)

2) You should know the labels' functions...

Speaking of nodes of Ranvier (NOR), diagram below shows how it works:
The impulse seems to 'jump' across the NOR to gain the speed.

Finally, we just realized a special relationship between the myelin sheath & the axon. Here is how I put it :-)
