Becoming Scientists Through Video Analysis by Ning Hwee Tiang

Becoming Scientists Through Video Analysis

Type: Contributed
This sharing highlights how the Tracker Video Analysis and Modeling Tool is used as a pedagogical tool in the effective learning and teaching of kinematics of a falling ball to grade 9 students in a Singapore classroom. Implemented with an inquiry-based approach, lessons facilitated varied opportunities involving students in active learning -- obtain real data, engage in evidence-based discussions, make inferences, and create a model to explain how the physical world works, in their technology-enabled environment. Students improved in sense-making and relating abstract physics concepts to real life. This work stems from a project collaboration (of four schools and education technology department) aim to encourage students to learn while behaving like scientists, aligned with the K12 science education framework. It has afforded teachers professional learning experiences, to be reflective and lead in their teaching practices. Hide description

Model:


The model assumes $ \vec {A} $ and  $ \vec {B} $ are added together to form vector  $ \vec {C} $

$ \vec {A} $  + $ \vec {B} $ =  $ \vec {C} $


In its components of x and y direction

$  A_{x} $  + $  B_{x}  $ =  $ C_{x}  $

$  A_{y} $  + $  B_{y}  $ =  $ C_{y}  $

SparksQ32014_Full.pdf


Sparks Quarter 3, 2014 issue, an Ministry of Education publication call us the sweet sixteen! I did realized there are 3 things that can improve the quality of the message.

User Experience:

  1. But the PDF is hardcoded where the texts and pictures cannot be copied.
  2. in the PDF , the words QS@MOE is not clickable?
  3. the email link does not bring to the correct page http://central.opal.moe.edu.sg/sparks/issues/issue-3-2014, instead it was http://central.opal.moe.edu.sg/sparks/

Solution:

  1. re save the original DOCX as PDF instead of the printing as PDF which could have caused this hardcoding.
  2. same as 1, the hyperlink should work now
  3. edit http://central.opal.moe.edu.sg/sparks/ to be http://central.opal.moe.edu.sg/sparks/issues/issue-3-2014
http://central.opal.moe.edu.sg/central/slot/u1040/issues/2014/SparksQ32014_Full.pdf



Thanks to OPAL highlights for Term 4, 2014!

author of EJS 5: Paco.


Engage:

Vectors are fundamental in the physical sciences. They can be used to represent any quantity that has magnitude, has direction, and which adheres to the rules of vector addition. For example, the weight force 4 N downwards could be represented by the vector $ (A_{x'},A_{y'})$ = (4 cos($ \theta $),4sin($ \theta $)) (in 2 dimensions with the positive x' and y' axis) if the slope is making an angle of ( 90 -$ \theta $) with the x' axes (assume slope surface from left to right downwards) .

Component along the x' and y' direction:

As explained above a vector is often described by a set of vector components that add up to form the given vector. Typically, these components are the projections of the vector on a set of mutually perpendicular reference axes (basis vectors). The vector is said to be decomposed or resolved with respect to that set. For simplicity, let's assume x and y direction as the reference axes, referring to the model above.
the equations for the components are:

 $ A_{x'} = A cos( \theta) $

 $ A_{y'} = A sin( \theta) $

Model:

This model uses the following equations:

Length or Magnitude |A|:

The length or magnitude or norm of the vector a is denoted by |A|.

 $ |A| = \sqrt {( A_{x'}^{2}+A_{y'}^{2})} $


Angle with positive x' axis:

The angle in radian of the vector that makes with the positive x axis is

$ \theta = tan^{-1} (\frac {A_{y'}}{A_{x'}}) $

the conversion to degree is

$ \theta_{degree} = (tan^{-1} (\frac{A_{y'}}{A_{x'}}) )( \frac{180}{\pi}) $

or

$ \theta_{degree} = ( \theta )( \frac{180}{\pi}) $

in the design of the slider values which shows in degree, the equation that converts back from degree to radian is used

$ \theta = ( \theta_{degree} )( \frac{\pi}{180}) $


Attribution:

when i made this model from a fresh ejss, the following works were reference from

  1. lookang, Fu-Kwun http://weelookang.blogspot.sg/2010/06/ejs-open-source-represent-vector.html
  2. Fu-Kwun, lookang  http://weelookang.blogspot.sg/2010/06/ejs-open-source-java-applet-resolving.html
  3. andreu glasmann, wolfgang christian, mario belloni Physlet Physics illustration 3.1. found in the Davidson College Digital Library for Physlets View the Physlet Two-Dimensional Kinematics Illustrations Package

Changes made:


  1. remade everything from lookang, Fu-Kwun http://weelookang.blogspot.sg/2010/06/ejs-open-source-represent-vector.html
  2. re-used some elements from andreu glasmann, wolfgang christian, mario belloni Physlet Physics illustration 3.1. found in the Davidson College Digital Library for Physlets View the Physlet Two-Dimensional Kinematics Illustrations Package to speed up development as per legally allowed by creative commons attribution, sharelike. i esepcially liked the ability to interact with the vector now, thanks to Prof Paco author of EJS 5.
  3. added ability to animate, thanks to idea from https://www.desmos.com/ and http://www.geogebra.org/
  4. added angle thanks to Prof Fu-Kwun guidance on some other works some years back!
  5. added ability to resolve along any perpendicular axes
  6. added ability to remember x' axes values after reset

Area of improvement:


  1. cannot figure out or cannot get the axis x' and y' to be drag-gable
  2. values to be shown on the view instead of the slider field

Example JavaScript Model Ill 3.1: Vector Decomposition written by Andreu Glasmann, Wolfgang Christian, and Mario Belloni


Other Good Model:

    https://www.geogebratube.org/student/m11066
    like: 1. ability to move vectors in screen, 2. values of components shown 5cos (60.16)
    dislike: 1. cannot fine control values example 60.16 instead of exactly 60

Event: MOE Professional Forum on Research and Practice (Poster Presentations)
Date:9 Oct 2014
Time: 0930-1540
Venue: AST Auditorium

Congratulations on the successful completion of your SSTRF projects!

2. The Research Committee and Professional Learning and Growth Committee of the Senior Specialist Council (with support by PDM secretariat) are organising the MOE Professional Forum on Research and Practice. This year, the forum will feature 4 presentation sessions, a panel discussion on professional practice and a poster session (during lunch).

3. Principal Investigators of all SSTRF projects completed in the 2013 cycle are invited to present their findings at the MOE Professional Forum on Research and Practice to be held on 9 Oct 2014, 0930-1540 hr at AST Auditorium. An internal evaluation committee (comprising senior MOE researchers) has reviewed 11 completed SSTRF projects and selected 3 for slide presentation and 8 (including yours) for poster presentation.

4. I would like invite your research team to prepare a poster to be presented at the MOE Professional Forum on Research and Practice. We would also like to invite you and your team members to be present at the poster presentation to explain your projects and to engage the audience. The programme and information on the MOE Professional Forum is given in the attachment.


6. To help in the poster preparation, colleagues from CRO have prepared a Poster Template (see attached) which you could use, if you wish. The poster is of the standard A1 size. My colleague, Kalthom, can help you print the poster if you send us the softcopy before 22nd Sep 2014 (Monday).

7. Please let us know if you and/or research team members will be able to be at MOE Professional Forum on Research and Practice to share your findings with the audience. We think they will learn much from you and I look forward to hearing from you soon.

Thank you very much.
