Sharing of teacher growth story by leongster

Thanks to bro for sharing. Let's not just let stories go unhear but be a constant remind to grow as an educator.

Teaching physics today is very different from 10 years ago. Back then, resources were a lot more limited.  Most of the learning is done by pen and paper. The experiential learning was often limited to physical experiments using simple lab equipment. Data loggers were limited in quantity and could only be done during scheduled lab sessions. The setup of the data loggers usually is predesigned and every student will be doing the same experiment designed by the teacher.

Today, teaching is a lot more exciting. There are many tools so readily available. Students are no longer passive receivers of knowledge but active constructivist of concepts. They are able to observe nature, ponder upon what causes the motion and investigate them like a true scientist using video analysis tools.

Take for example, my 9th grade students who use a high speed camera to study the flight of the bird. She could explain the difference in the wing motion between down stroke and up stroke and account for the force generated by the air in relation to the weight. She even study the rate at which the birds flap the wings to generate more forward force to accelerate itself initially during take-off and gradually changing the wing direction since it already has the velocity and only need minimal horizontal force to continue moving at the same velocity but require the same amount of vertical force to overcome its weight. As a teacher, all I taught her was how to use the tool and newton’s 3 laws of motion but she was able to explore beyond what any textbook or website can teach based on her own interest.

The best part about technology is differentiation. Every student was analysing an entirely different video based on their own interest. I have students studying her own gymnastic backflip, her father butterfly strokes, billiard balls collision, Coriolis effect of table tennis balls. What this 9th grader did was what I couldn’t imagine doing even when I was in the university.

In addition to video analysis, I’m now able to design games, simulations to observe phenomenon that was difficult if not impossible to setup.

I think open source physics is the key to moving education forward. Without the video tracker and easy java developed by universities professors for free, physics education would not be able to move at the rate it is currently moving. I would like to thank Lookang, Professor Wolfgang, Paco and Douglas for offering their shoulder so that we can see further.

My Tracker Analysis

excellent video by discovery education
download link1, link2
The motion can be classified into 5 sections

1. falling under gravity and drag force with parachute closed

model: vy = if(t<15,-1.230E-1*t^2+5.454E0*t+1.146E0,0)
in English, it means the parachutist is falling at |vy| = -0.123*t^2+5.454*t+1.146 m/s starting from t = 0 to 15 s


 2. constant velocity with gravity=drag with parachute closed

model: vy = if(t<15,0,if(t<57,55,0))
it means the parachutist is falling at |vy| =57 m/s from t = 15 to 57 s in the video

3.constant deceleration with parachute opening

model: vy = if(t<57,0,if(t<63.5,-5.934E0*t+3.932E2,0))
it means the parachutist is falling at |vy| = - 5.934*t +393 m/s from t = 57 to 63 s in the video

4.  constant deceleration with parachute fully opened

model: vy = if(t<63,0,if(t<71,-1.221E0*t+9.313E1,0))
it means the parachutist is falling at |vy| = - 1.22*t +93.13 m/s from t = 63 to 71 s in the video

5. constant velocity with parachute fully opened

model: vy = if(t<72,0,5.6)
it means the parachutist is falling at |vy| = 5.6  m/s from t = 63 to 71 s in the video

answer is C

From the video by Discovery Channel, it suggests that indeed as Mr Tan post on his blog, the answer for  parachute fully open is actually closer to C, instead of B as stated in Cambridge Marker's Report for the paper.
One up for peer review and open discussion. Thanks to Mr Tan's post!

Creating Electronic Books for Computers and Tablets Using Easy Java/JavaScript Simulations, EjsS Modeling Tool


Loo Kang Lawrence Wee
Ministry of Education, Singapore

Introduction and Theory

This paper shares my 2014 December journey (tools used, design principles derived and modeling pedagogy implemented) when creating electronic books-chapters (epub3 format) for computers and tablets using Easy Java/JavaScript Simulations, (old name EJS, new EjsS) Modeling Tool. The theory underpinning this work grounded on learning by doing through dynamic and interactive simulation-models that can be more easily made sense of instead of the static nature of printed materials.

Concept and Implementation

I have been developing stand alone EJS and more recently EjsS computer models to allow anyone to run them on their Android tablets and iPad. After the Singapore Easy Java/JavaS-cript Simulations, EjsS Modeling Tool workshop organised by Francisco Esquembre and Wolfgang Christian 25-28 November 2014, I started combining related computer models with supporting texts and illustrations into a coherent chapter, a logical next step towards tighter support for teachers and students.
I have since spent 6 months developing prototypes electronic chapters on the topics of Sim-ple Harmonic Motion and Gravity customized for the Singapore-Cambridge General Certifi-cate of Education Advanced Level (A-level).

Objectives and Assessment

I aim to inspire more educators to create interactive and open educational resources for the benefit of all and network with like minded educators to add elements of assessment for learning, such as automated marking in future releases of the electronic books-chapters.

AUTHORS: Lookang Lawrence Wee

OVERALL EVALUATION: 2 (accept)

----------- REVIEW -----------
The topic is of great interest because it points to the immediate future of science textbook publishing.

Although technical aspects are important, I would be particularly interested in learning about the design and pedagogical aspects of this work. What implications has the new media in the way the author writes the narrative and interacts with the embedded simulations?

The author mentions these aspects and I hope he insists on them in his presentation.

TITLE: Creating Electronic Chapters for Computers and Tablets using Easy Java/JavaScript Simulations, EjsS Modeling Tool
AUTHORS: Lookang Lawrence Wee

OVERALL EVALUATION: 2 (accept)

----------- REVIEW -----------
Creating and distributing interactive ePub 3 books is technically challenging and MPTL participants will be interested in learning about the author's experience developing the proof-of-concept eBooks referenced in the abstract. As stated in the abstract, the author has created many interactive simulations for use in Singapore schools and the materials in the author's eBooks are also available on his website in standalone html pages. It would be useful to learn if eBooks distribution is successful and if this new distribution mechanism is being compared to other distribution mechanisms and if the eBooks are being improved based on teacher feedback.

Abstract:

Introduction and Theory

This paper shares my 2014 December journey (tools used, design principles gleaned and modeling pedagogy implemented) when creating electronic books-chapters (epub3 format) for computers and tablets using Easy Java/JavaScript Simulations, (old name EJS, new EjsS) Modeling Tool. The theory is dynamic and interactive nature of physics knowledge can be more easily made sense instead of the static nature of printed materials. The new JavaScript code generating capability of EjsS has made the already widely used Physics education authoring toolkit, even more relevant in today's schools with no shortage of computers and tablets.

Concept and Implementation

I have been developing stand alone EJS thank to Fu-Kwun Hwang's NTNU Java Virtual Lab Forum and more recently EjsS computer models to allow anyone to run them on their Android tablets and iPad. After the Singapore Easy Java/JavaScript Simulations, EjsS Modeling Tool workshop organised by Francisco Esquembre and Wolfgang Christian 25-28 November 2014, I started combining related computer models with supporting texts and illustrations into a coherent chapter, a logical next step towards tighter support for teachers and students.
I have since spent 6 months developing prototypes electronic chapters on the topics of Simple Harmonic Motion and Gravity customized for the Singapore-Cambridge General Certificate of Education Advanced Level (A-level).

Objectives and Assessment

I hope to inspire more educators to create interactive and open educational resources for the benefit of all and network with like minded educators possibly adding elements of assessment for learning, such as automated marking in future releases of the electronic books-chapters.
