Similar to how stealth materials were developed to reduce the radar wave energy returning from an aircraft, here we explore a low-cost laboratory demonstration that uses similar principles to prevent detection of an object by an ultrasonic sensor. This demonstration setup can be used as a starting point to encourage students to explore the surface…

The damped harmonic oscillator physics problem is a standard oscillation problem in calculus physics for pre-engineering students in a community college. The use of alternative linear algebra eigenvalue stability method is consistent with the upper engineering courses using control theory. The external force and friction damping would become the…

Asensor of the type BMP180, together with Arduino, is used to easily measure atmospheric pressure and temperature at schools. The open source Arduino microcontroller board presents countless teaching applications in science and engineering projects. It allows students to implant their creativity into a friendly environment and take ownership of…

I have long incorporated physics simulations in my physics teaching, and truly appreciate those who have made their simulations available to the public. I often would think of an idea for a simulation I would love to be able to use, but with no real programming background I did not know how I could make my own. That was the case until I discovered…

Over the past two years, the AAPT/ComPADRE staff and the Open Source Physics group have published the second edition of "Physlet Physics" and "Physlet Quantum Physics," delivered as interactive web pages on AAPT/ComPADRE and as free eBooks available through iTunes and Google Play. These two websites, and their associated books,…

Aim/Purpose: This paper presented the framework for the integration of digital technologies in education, implemented in InTecEdu Program, developed by Remote Experimentation Laboratory (RExLab), Federal University of Santa Catarina (UFSC), Brazil. Background: The main objective of the model presented is to arouse interest in science and…

The distribution of the education quality in Indonesia is relatively uneven. This affects the quality of secondary school graduates. On the other hand, the national growth of Information Communication Technology usage in Indonesia is very high, including the use of mobile technology. This is an opportunity for the application of OER (Open…

This article reports on the use of Tracker as a pedagogical tool in the effective learning and teaching of projectile motion in physics. When a computer model building learning process is supported and driven by video analysis data, this free Open Source Physics tool can provide opportunities for students to engage in active enquiry-based…

This study describes the possibility and advantages of utilizing simple computer codes to complement the teaching techniques for high school physics. The authors have begun working on a collection of open source programs which allow students to compare the results and graphics from classroom exercises with the correct solutions and further more to…
