20170123 TRAISI 41190 workshop 2017 ICT Learning Experiences for Teaching Kinematics eduLab@AST

 

email by leongster

Dear colleagues,

We are running a 4 workshop series for “Creating ICT Learning Experiences for Kinematics/Dynamics/Energy”.

Through the 4 sessions, we hope to give you a deep physics learning experience so that you can bring it back to your students.

Unlike usual ICT lessons, the focus of these workshops will be pedagogy, practices of science and network learning.

 

Typically students view

  • kinematics, dynamics, work energy and power as 3 separate topic.
  • physics as a tool for assessment rather than real world application.
  • science as some facts passed down from dead physicist

Through the workshop, we will share how to

  • teach kinematics, dynamics, work energy and power, in a more coherent way
  • teach with real-world context and data
  • teach students understand the nature of science without spending extra curriculum time
 

We will introduce different features of the tracker software and simulations during each lesson, guide you through interactive inquiry activities and group you with people of similar interest so you can continue to grow as part of the ICT Network Learning Community.

The workshop is FREE and presented by Leong Tze Kwang from CPDD, Wee Loo Kang from ETD. We will also be inviting guest from various school who have tried out the tools to share their experience and challenges.

Or if you know teachers who are interested, please forward this to them and invite them to sign up for the courses at Traisi.

Ideally, we will prefer that you come for all 4 sessions but you can still follow if you cannot make it for some of the session.

Look forward to seeing you at the workshop

50+25 min (LK & MY & TK) (Jit Ning) Summary Introduction to Tracker, a video analysis and modeling tool 

  1. Ask Question, example, how to describe the physics of a falling object? and make prediction
  2. Use Model, example, how is position, speed, acceleration, related to time? y, vy, ay, t
  3. Carrying out investigation 
    • OPTION BEST: Use personal handphone, record and send by email to yourself, login to email and download file into the laptop and use Tracker to open it
  4.  to record motion of a falling object and using Tracker mport the video file and to track collect data.
  5. Analyse data, in Tracker analyse the data such as gradient, average, etc that can help you to answer Practice 1 
  6. Using mathematical thinking, using the same data collection, suggest a kinematics model example ????? y = y0 + uy*t+0.5*ay*t^2 
  7. Constructing explanation, discuss with group mates and word the findings. 
  8. Argue from evidence, if you disagree with the views of the group mates, using the data
  9. Communicate information, present the group findings

Step by Step tutorial with screenshots may not be covered completely, will spend more time for teacher to share how to overcome challenges

  1. Ask Question, example, how to describe the physics of a falling object? and make prediction
    • will heavier object fall faster than lighter objects?
    • will object thrown forward falls slower?
    • does object toss up and fall down experience same acceleration?
  2. Use Model, example, how is position, speed, acceleration, related to time? y, vy, ay, t
    • how is the gradient of the position versus time graph changing with time?
    • what is the equation that describe the 
      • position time graph?
      • velocity time graph ? 
      • acceleration time graph?
  3. Carrying out investigation 
    1. OPTION BEST: Use personal handphone, record and send by email to yourself, login to email and download file into the laptop and use Tracker to open it
    2. POOR RESOLUTION: http://www.wikihow.com/Record-from-a-Webcam to record motion of a falling object and using Tracker import the video file and to track collect data.
    3. use existing video available on Tracker itself , Collections | Shared Library | Singapore Tracker Digital Library | 00workshop | 2017Leongster

    4. Install tracker http://physlets.org/tracker/
    5. launch Tracker from the Windows | Start | Tracker | Tracker ,assuming you have already installed it 

    6. The start screen of Tracker looks like this, if prompted to restart Tracker, do so to get the video engine working 

    7. Select File | Import | and choose the video file you made, best if you can copy the video to the Tracker video before importing it. For my personal computer the folder is C:\Users\weelo\Documents\Tracker , but for eduLab computer is could be the D:\Tracker.  

    8. you will perform the same steps on your own video, while i will show the steps on a Digital Library resource of the same phenomena, Ball Drop and double click to download the file with analysis and raw video

    9. the tracker *.trz loads successfully to show the video with the saved analysis 

    10.  Select all the mass and Models and make them visible = false to hide all the existing tracks, to simulate as if you are doing a brand new video 

    11. Step 1 is define clip start and end frame, you have to look at your own video to decide the part which has physics you want to study. Use either the icon on top for clip setting or the 2 black triangles drag to desired time and release the mouse.

    12. Step 2 is calibrate the pixels on the video that tells Tracker the length of the video, for example if i used a one metre ruler, i would key in 1.000 for m 

    13. Step 3 define the world cartesian coordinate system, position the centre (0,0) by dragging the centre cross, do not rotate the axes because we want students to do a simple X and Y axes with no rotation 

    14. Step 4 Create a new Point Mass 
    15. Tracker automatically names the new mass as Mass A or something similar

    16. Hold down the shift key on your keyboard, a new cursor appears, click on the position of the mass you want to track, the end should look like this by default on x axis 

    17. since this motion is on the y direction, select the label x and turn it into y and you should get a scientific representation of position y versus time, t.

    18. remember to save your work regularly, this concludes the data track section.
    19. cool fun stuff you may want to try is to move the video clip to different time to observe the data points. remember to discuss and ask questions.
  4. Analyse data, in Tracker analyse the data such as gradient, average, etc that can help you to answer Practice 1 https://sg.iwant2study.org/ospsg/index.php/145 download falling ball worksheet tracker 4.84.docx
    1. Gradient Analysis.
    2. in any right panel, do a right click on your mouse to invoke options. 

    3. Select the Analyze option, and a pop up window is launched showing exactly the same panel say, it was y vs t 

    4. for gradient, select Measure 

    5. move your mouse cursor to data point of interest, the bottom right corner shows the value for the slope, which is another name for gradient, which is slope = - 2.87 E0 where E means exponential = - 2.87 m/s 

    6. so the tool can be used but it rely on the user-student to decide what is meaningful to analyse as gradient of y vs t graph does have a physical meaning, such as instantaneous velocity which needs a skillful teacher to guide the students to discover.
    7. Average
    8. average is also selectable on the same pop up analyze window 

    9. the average is the same as mean , and here the table shows mean of y = -5.461E-1 = 0.5461 m
    10. typically average of y position isn't very useful as it is just an average of position y during the time duration of analysis, but now go back to the Tracker video and select ay instead of y 

    11. again, right click and choose analyze 

    12. the pop up window for analysis now shows both y and ay, unselect y, to just look at the ay data versus t 

    13. the result of this deselection 

    14. reveals the meaningfulness of such a data analyzed
  5. Using mathematical thinking, using the same data collection, suggest a kinematics model example ????? y = y0 + uy*t+0.5*ay*t^2 
  6. Constructing explanation, discuss with group mates and word the findings. 
  7. Argue from evidence, if you disagree with the views of the group mates, using the data
  8. Communicate information, present the group findings
