2D-Ising Model
Conditions of Use:
Read the Fine Print
Rating

The EJS 2D Ising model displays a lattice of spins. You can change the lattice size, temperature, and external magnetic field. You can modify this simulation if you have Ejs installed by right-clicking within the plot and selecting “Open Ejs Model” from the pop-up menu item. The 2D-Ising model was created using the Easy Java Simulations (Ejs) modeling tool. It is distributed as a ready-to-run (compiled) Java archive. Double clicking the ejs_stp_Ising2D.jar file will run the program if Java is installed. Ejs is a part of the Open Source Physics Project and is designed to make it easier to access, modify, and generate computer models. Additional Ejs models are available. They can be found by searching ComPADRE for Open Source Physics, OSP, or Ejs.

3-D Hydrogen Atom Probability Densitites
Conditions of Use:
Remix and Share
Rating

The 3-D Hydrogen Atom Probability Densitites model simulates the probability density of the first few (n = 1, 2, and 3, and associated l and m values) energy eigenstates for the Hydrogen atom (the Coulomb potential). The main window shows the energy level diagram for the solutions to the Coulomb potential in three dimensions. States may be selected either by using the dropdown menu item or by using the energy level diagram and clicking a dark green level, with specific n, l, and m values) which will turn bright green and change the state shown in the 3d visualization window. The probability is shown with a 3d cloud, with higher probability shown as a darker sphere. The simulation uses either simple 3D or Java 3D (if installed) to render the view the probability densities. If Java 3D is not installed, the simulation defaults to simple 3D using Java. The 3-D Hydrogen Atom Probability Densitites model was created using the Easy Java Simulations (EJS) modeling tool. It is distributed as a ready-to-run (compiled) Java archive. Double clicking the ejs_qm_hydrogen3d.jar file will run the program if Java is installed.

Talk FC06 in the "Computational and Online Tools for Teaching Physics" session highlights the Open Source Physics (OSP) community of educators that engage, enable and empower teachers as learners so that we create DIY technology tools-simulation for inquiry learning. We learn through Web 2 online collaborative means to develop simulations together with reputable physicists through the open source digital library. By examining the open source codes of the simulation through the Easy Java Simulation (EJS) toolkit, we are able make sense of the physics from the computational models created by practicing physicists. We will share newer (2010-present) simulations that we have remixed from existing library of simulations models into suitable learning environments for inquiry of physics. We hope other teachers would find these simulations useful and remix them that suit their own context and contribute back to benefit all humankind, becoming citizens for the world.

This activity lets you program your 'robot' (a willing friend) to pick up and dispose of some 'toxic waste' using as few commands as possible. Learners create command cards (Turn Left, Right, Forward 1, etc.), mark out a simulation area on the floor, and try to get the "robot" to dispose of something that serves as "toxic waste" into something that serves as a "containment vessel" - in as few steps as possible. Strategy, predication and cooperation are all part of this activity.

In this activity, learners will listen to as many radio stations as possible to discover that AM radio signals can travel many hundreds of miles at night. Learners log the call signs, locations, and quality of the transmissions on a data table. This resource includes information about how AM radio transmissions differ at day and night, the ionosphere, the history of call letters, and NOAA Weather Radio. Note: this activity must be completed during the evening or early in the morning before sunrise and learners must have access to an AM radio.

Accelerating Geophysics Simulation using CUDA
Conditions of Use:
Read the Fine Print
Rating

CitcomS, a finite element code that models convection in the Earth's mantle, is used by many computational geophysicists to study the Earth's interior. In order to allow faster experiments and greater simulation capability, there is a push to increase the performance of the code to allow more computations to complete in the same amount of time. To accomplish this we leverage the massively parallel capabilities of graphics processors (GPUs), specifically those using NVIDIA's CUDA framework. We translated existing functions to run in parallel on the GPU, starting with the functions where the most computing time is spent. Running on NVIDIA Tesla GPUs, initial results show an average speedup of 1.8 that stays constant with increasing problem sizes and scales with increasing numbers of MPI processes. As more of the CitcomS code is successfully translated to CUDA, and as newer general purpose GPU frameworks like Fermi are released, we should continue to see further speedups in the future.

Adding It Up: Helping Children Learn Mathematics
Conditions of Use:
Read the Fine Print
Rating

This 440-page report explores how students in pre-K through grade 8 learn mathematics, with a focus on number and operations, and recommends how teaching, curricula, and teacher education should change to improve mathematics learning. (A 39-page summary, Helping Children Learn Mathematics, is catalogued separately.) The authors identify five interdependent components of mathematical proficiency and describe how students develop this proficiency. The report presents a portrait of mathematics learning: research findings on what children know about numbers before they arrive in pre-K and the implications for instruction; details on the processes by which students acquire mathematical proficiency; what is known from research about teaching for mathematics proficiency and developing proficiency in teaching. Visitors to this website may read the full text online, download a copy (pdf), or purchase a hard copy.
