Ejs Open Source Collision Carts Model with AJC and RVHS

Ejs Open Source Collision Carts Model with AJC and RVHS
Ejs open source java applet 1D collision carts Elastic and Inelastic Collision Java Applet by lookang, based on a original model by written by Francisco Esquembre found in Ejs itself as an example.

Scaling

AJC and RVHS is going to lead the implementation with the others schools


of course with inputs from RVHS, SRJC, YJC, IJC and AJC.

This is the research design by AJC.


Quantitative Study
Hypothesis:
The use of computer model (collision carts) in the learning of momentum may improve students’ understanding through (1) multiple representational visualizations and (2) guided inquiry pedagogy*
Independent variable:
  1. Use of teacher created EJS computer model in learning of momentum, newton's first law with pedagogical features that enhance multiple representations and guided inquiry learning
Dependent variable:
  1. Students’ understanding deepened that probably may be measured through
    1. (short term gains) Interviews, surveys, students’ worksheet
    2. (longer term transfer of performance gains) such as
                                                               i.     ?? Post test 2 Tier MCQ (15 qns) *Open ended qns for 2nd Tier (right after lecture)
                                                             ii.      ??Common Test (may not have)
                                                            iii.      ?? Academic performance  in summative exam (may not have)



Qualitative study
General Question: How has the use of computer model (collision carts)  helps you in understanding the concepts of momentum, energies newton's first law?
Specific Questions:
  1. How has computer model (collision carts)  helped in you in understanding the concept of momentum, energies newton's first law?
  2. What learning features do you feel deepen learning in the computer model (collision carts)?
  3. How can computer model (collision carts)  be improved to help you understand the principle of momentum, energies newton's first law?
