HOW DOES CURRENT FLOW? OHM’S LAW

IDevice Icon Important Information

 

This module is a didactic material for the final activity of online training course "Transforming curriculum with remote experimentation: how to integrate it in secondary school classroom" - implementation of remote laboratory in class instruction. The teacher can use it in class instruction based on the needs, as a
(1) whole product using theoretical materials,
(2) part of tests, simulations and remote laboratory (RL) exercises
(3) only the remote laboratory exercises

The learning modules´ remote experiments are provided in the connection with topic theory appointed for building student competence in national curriculum. This allows the teacher to implement the innovative approach without the modification of the curriculum.

Because of the basic principle of the remote laboratory the provided experiments for the remote laboratory could be modified ONLY after discussion with owner of the RL - WebLab-Deusto representative. Please contact:
Javier Garcia-Zubia (zubia@deusto.es).

Learning outcomes addressed by the module

At the end of learning, having successfully implemented all tasks and assignments, learners will be able to:

  • Design real experiments that will confirm the hypotheses; build a practice to work with laboratory materials and equipment; make a progress in terms of practical assembly work skills; take measurements properly; and draw conclusions based on the measurements taken.
  • Examine direct current circuits using terminology, formulas and analytical methods associated with direct current circuits´ concept.
  • Use basic concepts and general information about electricity.
  • Use specific symbols to represent electrical diagrams; comprehensive analyse devices and components involved in technical activity in order to explain how they work, their usage and control.
  • Understand the relationship between direct current, voltage and electrical resistance using the VISIR remote experiment.
  • Using the VISIR carry out a research of the nature of alternating current and RC circuits.
  • Describe the phenomena that can be observed in problems that occur in daily life in terms of relevant identified variables.

Duration: 20 hours include learning hours + time for exercise completion (distribution will depend on the teacher implementation strategy)
