Discussion and Outlook….

  • The remote experiments will play a decisive role in gaining

interest, motivation and individual involvement in pedagogical process using remote experiments covering various areas of Natural sciences, entering lectures, seminaries, laboratory exercises, project work, examinations and self study, or in general Integrated e- Learning.

Discussion and Outlook….

  • The remote experiments will play a decisive role in gaining

interest, motivation and individual involvement in pedagogical process using remote experiments covering various areas of Natural sciences, entering lectures, seminaries, laboratory exercises, project work, examinations and self study, or in general Integrated e- Learning.

  • The ISES technology of hands on experiments in Natural

sciences is extremely suitable for the computer oriented experiments on both university and secondary school level,

slide-27
SLIDE 27

Discussion and Outlook….

  • We hope to attract young people, used to exploit the

Internet for the casual playing, chatting and communication purposes, for real work with the planned goals and aimed and involved output and to persuade them about the information The ISES technology of hands on experiments in Natural sciences is extremely suitable for the computer oriented experiments on both university and secondary school level.

  • The pedagogical research in using of remote experiments

proved the hypothesis of increased involvement of both students and teachers into pedagogical process.

Conclusion Johan Amos Comenius (1592-1670) „ There is a permanent point at issue of pedagogy, striking the right balance

  • f the teaching content and form,

where the question is to find the way according to which those who teach would teach less, but those who learn would learn more.“
