3rd Meeting Java Sims


I think our project is progressing well and it is time again to share our collective understanding to benefit the communities within and outside this project.

Below is the draft agenda for your edits for a meaningful meeting.

Date: 27th april 2012
Time: 1500-1730
Venue: Yishun JC
Room: Conference Room Meeting room 1
Possible Guests:  I took the liberty to invite them to understand the good work that we are doing. They may or may not come
1.       Charles Chew, AST
2.       Barnabas Tan, Huang Kexin, Joy Tan , CPDD


Agenda:
1.       Sharing of past research on lesson packages with focus on,
a.       current state of the lesson package
b.      research insights, evidence data, student artifacts
c.       research paper for conference or journal if any planned

Ai phing and alysious goh will attend the WCPE representing the team's work.


•         AJC
Alysious will implement collision cart soon.
Ee-peow has begin to collect survey data using the google form with his enhancement fields like gender etc.

Tat leong Rvhs shared his class used the emi applet and the model is improved and data waiting for analysis.

•         IJC

Soo Kok shared the data with 4% higher post test score using interactive engagement lesson 12% (N=53) using ejs ripple tank model than demonstration 8% (N=59) based on a equivalent grouping based on equal pre test score.
Interesting facts include:
Hake gain formula used
Analysis and finding consistent with hake paper
initial finding based on un-equivalent grouping suggests 0.2% in favour of interactive engagement using ejs ripple tank model.

YJC shared using ripple tank level wide implementation using a blended demo plus hands on using model.

Teachers are encouraged to get more students to complete the survey.

•         SRJC

Chew ling shared her classes used the emi model
Joshua shared his colleague are skeptical of improved learning gains in terms of test scores.
One way of look at this is learning is based on experience, without experience, learning is not deepen and we argue for deep learning as oppose to surface 'learning' for exams smart.


•         YJC

Jimmy share the gravity models will be implemented on term 3.
2 as labs
2 In tutorial as experiential activities.

•         RVHS

Ai phing shared Rvhs findings and teacher interview.
The lesson package is suitable for after lecture, testing more on concepts and application.

•         ETD



o   share using excel spread sheet to analyze data requested by IJC

Our abstract is:
We are teachers who have benefited from the Open Source Physics (Brown, 2011; Christian, 2010; Esquembre, 2010) community's work and we would like to share some of the computer models and lesson packages that we have designed and implemented in five schools in the grade 11 to 12 classes.
In a ground up teacher leadership (MOE, 2010) approach, we came together to learn together, advancing the professionalism of physics educators and improve students' learning experiences through suitable blended of real equipment and computer models. We will share computer models that we have remixed from existing library of computer models into suitable learning environments for inquiry of physics customized (Wee & Mak, 2009) for the Advanced Level Physics.
We hope other teachers would find these computer models useful and remix them that suit their own context and contribute back, design better learning activities and share back, to benefit all humankind, becoming citizens for the world.
This is an eduLab (Wee, 2010) project funded by the National Research Fund (NRF) Singapore and Ministry of Education (MOE) Singapore.

Newton's Law of Cooling
The Newton's Law of Cooling model computes the temperature of an object of mass M as it is heated by a flame and heated or cooled by the surrounding medium. The model assumes that the temperature T within the object is uniform.  This lumped system approximation is valid if the rate of thermal energy transfer within the object is faster than the rate of thermal energy transfer at the surface. 


Newton assumed that the rate of thermal energy transfer at the object's surface is proportional to the surface area and to the temperature difference between the object and the surrounding medium.

dQ/dt = h*A(T-T0)

where h is the heat transfer coefficient and A is the area of the object.  Combing Newton's law of cooling with the definition of specific heat C and assuming that the specific heat is constant gives

dT/dt = - [h*A/(M*C)]*(T-T0)


Users can select the mass of the object and the material and the model computes the surface area assuming a cubic shape. The model plots the object's temperature as a function of time as the user heats and cools the object.  A data-tool button on the temperature graph allows users fit the data to analytic functions.
 
Note:  A typical (rough) heat transfer coefficient h for still air and iron is 6 W/(K m^2) and 400 W/(K m^2) for still water and iron. The Newton's Law of Cooling model assumes h=400 for all materials.  The actual value of h depends on many parameters including the material, the fluid velocity, the fluid viscosity and the condition of the object's surface.

You can examine and modify a compiled EJS model if you run the model (double click on the model's jar file), right-click within a plot, and select "Open EJS Model" from the pop-up menu.  You must, of course, have EJS installed on your computer.  Information about EJS is available at:

I can be more entertaining if I can do this, than to talk boringly about theories and trends.
This demo can achieve student-centric curriculum re-design because students become scientist and modelers of theories, rather than passive recipients of knowledge


version 1
Title: implementing e-learning with open source physics computer models.

version 2
Title: Exploring the Process of Scaling up with Open Content.
Abstract: Educational resource plays a key role in allowing teachers to design e-learning environment, but open content (Johnson, Levine, Smith, & Stone, 2009; Johnson et al., 2010) to quality educational resource is still not a norm. Some of the challenges faced by teachers in schools include 1) copyright infringement & ease of access and 2) ability to remix resources & lack of time, knowledge and skills, are some of the barriers for teachers to use e-resources. This can be examined from a 1) Sustainable & Spread and 2) Shift of ownership and Evolution and Depth, dimensions of scaling (Dede, 2006). Case studies in Education Technology Division of MOE Singapore will be shared as innovative diffusion examples, using the 5 dimensions of scaling as framework to examine the sharing of e-resources. Examples used will be drawn from research projects lead by the speaker and they are:
  • 14 Physics Demonstration videos on YouTube, collaboration with NUS Physics
  • 8 Computer models and Tracker (Brown, 2007) in NRF2011-eduLab001 Java Simulation Design for Teaching and Learning project, funded by National Research Fund (NRF) & MOE, collaboration with Open Source Physics (Brown, 2011; Christian, 2010; Esquembre, 2010; Hwang, 2010) researchers all over the world.
The views expressed are the speaker own and does not in any way represent the organizations.
