The virtual instruments development has led to lessons based on virtual experiments – applications that simulates real-life phenomenon and are specially designed for students use. Many virtual experiments can be obtained free of charge from the Internet, but their use in the classroom involves more than these tools availability. It involves the use of new teaching techniques and training materials. Through a European project, hundreds of teachers of sciences were trained to develop and implement virtual experiments in the classroom. This paper presents some of the expectations of teachers before the start of the training course and their opinion after the class implementation. ER
