Simulation of Gas Exchange in the Alveolus and Body Cells



A very simple demonstration but yet giving much impact on the students' understanding and concept construction.


Simulation.


So today, 3 Daisy demonstrates the simulation of the process of gas exchange in the alveolus and body cells.

To view the full-length simulation in youtube, click on the link below:
Simulation of Gas Exchange in the Alveolus

Last year we did the simulation on the school field n its quite tiring n hot.

But this year, hopefully, the video is clearer for sight and sound as it was done in the school hall.

Below is the short video of the simulation:


At the end of this learning session, hopefully, students are able to explain the process of diffusion in the alveolus n blood cell.

or complete the flow map (i-think map) to show the sequence of gas exchange in the alveolus n body cells.

1. Oxygen enter alveolus
2. Process of diffusion in the alveolus
3. Hemoglobin transport oxygen in the  blood capillary to the body cells
4. Process of diffusion in the body cells
5. Hemoglobin transports carbon dioxide to the alveolus.
6. Process of diffusion in the alveolus

This activity is as the enhancement than what the teacher had taught in the classroom which exhibits creativity, communication and collaboration.

Peer Assessment; my Best Practice. Planning, Implement and Assessment Guide for KSSM Science PT3

Chapter 2: Human Respiratory System


Assalamualaikum wbt and have a good day ahead.

The word  'best practice' had been circulating my mind in the past few weeks. I've been thinking of writing about my best practice in the classroom and share it in the blog and get feedback about it.



What is the definition of "Best Practice" in education?

I am still in search of it... I hope YOU can help me with this. From my understanding; Best Practice is something or anything that "works"! as for the teachers, we want to achieve the Learning standard with fruitful results in a manageable time by implementing ACTIVE learning, technology/STEM embedded and adapting 21st-century learning elements such as 4C's. Still, remember 4C's? Communication, collaboration, creativity, and critical thinking.

"Teachers give students opportunities to become problem solvers who take responsibility for their own thinking"

.................................................................................

There are many examples of Best Practice in the classroom. For now, I want to share my best practice for peer assessment.

1. Planning

Plan early. You don't enter the class and suddenly had this in mind. It must be planned properly by setting up the next activity while students are completing the current one. This makes for a smooth and speedy transition from one activity to the next.

2. Implementation

    (i)    Giving instruction

- Design the end goals and end product first (Backward planning)


- Give a room for clear instruction on the task that you had planned before the class.
A handout would be sufficient.

 Example of instruction

- To design a model, give some examples and ideas of their end product/outcome.
A rubric would be sufficient.

Example of Rubric

    (ii)   Sufficient time

Give ample time for the students to discuss in group, plan for the activities, writing the report and plan for the way they choose to present their report of the task.

    (iii)  Continuous assistance and progress report

For the KSSM students,  whether they are in Form 1, Form2 or Form 3, in my opinion, it is best for the teacher to observe the students' progress on the task that had been given. Give continuous assistance and support.


3. PEER ASSESSMENT

Let them present in the class.

(i) If the task is an individual task, let them present in a group where each of the group members would give marks/grades based on the rubric prepared by the teacher.

(Rubric for an individual task usually is more simple/easy/uncomplicated)

(ii) If the task is a group task and the class has 6 groups of four students (total number of students in class = 24), then give every group the rubrics and they will evaluate the other groups' end products with the rubric.

(Rubric for a group task usually is more complex; which they have more objectives to be achieved)


This will be the atmosphere in the classroom:







Teachers, you will be surprised when doing this activity you find the most creative students come from the lower achievement class, whereas the need-to-do-again model comes from the higher achievement class.



a good example 🎕
a good bad example 😀
