Poster: “Radiation Remote Laboratory” with Two Level Diagnostics

The paper describes the remote experiment “Radiation Remote Laboratory” with two levels diagnostic system, built on ISES - Internet School Experimental System, accessible across the Internet and provided via the system REMLABNET (http://www.remlabnet.eu/). The remote experiment strives to provide the basic knowledge on γ radioactivity and/or γ radiation and its basic application laws, and parameters like its Poisson distribution, intensity dependence on distance from the point source and provides basic ideas about its absorption in various materials. Absorption in Cu on thickness of the Cu material is possible to examine in detail. Besides, this experiment serves to develop the basic knowledge for handling the radioactive materials in education and practice.

Remote diagnostics of remote laboratory — On example of Joule's experiment as a probe into micro world

Real remote laboratory experiment on Joules experimentation has both the historical and pedagogical importance in the building of the bridge between macro and micro world. Dissipative forces and their work as a transformation of the macroscopic mechanical energy into the energy of thermal movement are decisive in the study of mechanical phenomena of real world. The remote experiment should both qualitatively and quantitatively describe the transformation of macroscopic kinetic energy into heat and show the quantities, active in the transformation. The remote experiment represents a new generation of ISES remote experiments. The measureserver is equipped with a new diagnostics block, enabling diagnosis information on remote experiments both for the client and the provider.

Electrochemistry remote experiment - galvanic cell - II

The paper is a free continuation of the paper presented at the REV 2009 conference, where we reported about remote experiment “Electrochemical cell characterization - is it a start of remote experiments in chemistry education?”. As a matter of fact it was meant as a small spur to the chemistry instructors to inspire them to build remote experiments, which are scarce in literature even now after three years. We want to present the continuation to the 2009 talk, showing what may be gained from a chemical remote experiment data, which wealth of information it may bring if properly used. We show how the experiment Electrochemical cell with controlled change of the electrolyte concentration and simultaneous measurement of electromotive force and electrolyte conductivity provides the possibility for the elucidation of the electrolyte conductivity, decision about strong/weak electrolytes, ions mobility and the study of Fermi level of various metals and reaction constant (http://remotelab2.truni.sk ). In the paper we want to use the experience gained in the meantime with the experiment Electrochemical cell and show all the possibility it offers. Paper may serve for inspiration to build, using ISES system, similar experiments for chemistry education.

Faraday's Law via e-experiments as an example of inquiry-based learning

The contribution demonstrates a practical application of the strategy of Integrated e-Learning via hands-on, remote and virtual experiments by means of the prepared interactive teaching tool in the form of a webpage titled “Electromagnetism” (http://e-materialy.net76.net/index.html). It is designed in accordance with the method of inquiry-based learning where the active involvement of the students in the construction of their knowledge plays a decisive role. The paper presents the possibility of the utilization of e-experiments to secondary school physics education. The design and the realization of simple electromagnetic experiments as well as the remote experiment Faradays Law are also introduced (free available on http://remotelab4.truni.sk/faraday.html).
